Effect of isotonic exercise on cardiovascular parameters in medical students with parental history of hypertension – An institutional study

Background: Hypertension (HTN) is one of the most common and a high-risk factor for cardiovascular disease. Aims and Objectives: This study aims to identify students who are at risk of developing HTN with positive parental history of HTN and to compare the effects of isotonic exercise on cardiovascular parameters among the students with and without positive history of parental HTN. Materials and Methods: A total of 50 students participated in the study out of which 21 students had positive history of parental HTN with at least one parent having history of HTN and 29 students had negative history of parental HTN. Baseline pulse rate (PR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) of the participants were recorded. Then, all the participants performed Harvard step test for 3 min. The SBP, DBP, and PR were measured immediately after stopping the exercise and after 3 min and after 5 min of stopping the exercise. Data were statistically analyzed using unpaired t-test and ANOVA. P < 0.05 was considered statistically significant. Results: PR recorded after 3 min of stopping of exercise was significantly higher in the participants with positive parental history of HTN than the other group. SBP recorded immediately and after 3 min and after 5 min of stopping exercise was significantly higher in the participants with a positive history of parental HTN as compared to the other group. However, no statistically significant difference was observed in DBP between the two groups. Conclusion: Students with positive parental history may have relatively higher risk of developing HTN in future as an exaggerated blood pressure response to exercise was observed in them in this study.

Changes in chloremia, secondary to hydric reanimation during the first 24 hours, increases hospital stay and complications in patients with acute pancreatitis / Cambios en la cloremia secundaria a la reanimación hídrica, en las primeras 24 horas, incrementa la estancia hospitalaria y las complicaciones en los pacientes con pancreatitis aguda

Abstract Acute pancreatitis (AP) requires first-line treatment with intensive fluid resuscitation. Hydroelectrolyte changes secondary to this management could be related to an increase in hospital stay, complications, and mortality. The objective of this study was to correlate the increase in serum chlorine (> 8mEq / L) during the first 24 hours (ISC) with a longer hospital stay, complications and mortality in patients with AP. A total of 110 patients with AP admitted to the emergency room were included. Fluid management and serum chlorine were recorded on admission and after 24 hours; duration of hospital stay, complications and mortality, were also registered. 37 patients had ISC (age 56.4 ± 18.4 years; 51% women), there were no differences in age, sex or type of fluid management with patients without ISC. In bivariate analysis, ISC was associated with severe AP (30% vs 12%, p = 0.02), higher APACHE II score at admission (8 [6-15] vs 6 [4-9] points, p = 0.006), and longer hospital stay (9 [7-12] vs 7 [5-10] days, p = 0.03). The overall mortality and complications rate were 16% and 25%, respectively, with no differences between the groups (24% vs. 12%, p = 0.1 and 35% vs. 19%, p = 0.06). After multivariate adjustment, independent predictors of hospital stay were ISC> 8 mEq / L (p = 0.01) and APACHE II scores at 24 hours (p = 0.02). We conclude that ISC is associated with a longer hospital stay in patients with AP from a second-level hospital care population.

Resumen La pancreatitis aguda (PA) requiere tratamiento de primera línea con reanimación hídrica intensiva. Los cambios hidroelectrolíticos secundarios a este manejo podrían relacionarse a un incremento en la estancia hospitalaria, complicaciones y mortalidad. El objetivo de este estudio fue correlacionar el incremento de cloro sérico (>8mEq/L) en las primeras 24hrs (ICS), con una mayor estancia hospitalaria, complicaciones y mortalidad en pacientes con PA. Se incluyeron 110 pacientes con PA ingresados a urgencias, se registró el manejo hídrico y cloro sérico al ingreso y 24 horas después, la estancia hospitalaria, complicaciones y mortalidad. 37 pacientes tuvieron ICS (edad 56,4 ± 18,4 años; 51% mujeres) no hubo diferencias en edad, sexo o tipo de manejo hídrico en pacientes sin ISC. En el análisis bivariado, el ICS se asoció a PA grave (30% vs 12%, p = 0,02), mayor puntuación APACHE II al ingreso (8 [6-15] vs 6 [4-9] puntos, p = 0,006) y estancia hospitalaria más prolongada (9 [7-12] frente a 7 [5-10] días, p = 0,03). La tasa global de mortalidad y complicaciones fueron del 16% y el 25%, respectivamente, sin diferencias entre grupos (24% vs 12%, p = 0,1 y 35% vs 19%, p = 0,06). Después del ajuste multivariado, los predictores independientes de la estancia hospitalaria fueron ICS> 8 mEq/L (p = 0,01) y las puntuaciones APACHE II a las 24 horas (p = 0,02). Concluimos que el ICS se asocia a mayor estancia hospitalaria en pacientes con PA de una población de segundo nivel de atención hospitalaria.

Delayed onset muscle soreness intensity affects muscular performance / El Dolor muscular de aparición tardía afecta el desempeño muscular

Abstract Background: The study of functional impact of delayed onset muscle soreness has been limited to describe the decline on maximal isometric contraction, but muscular work and time to peak torque has not been examined yet. Purpose: To describe the changes induced by a session of lengthening contractions on muscle performance and delayed onset muscle soreness (DOMS). Methods: A quasi-experimental study was conducted in the Institutional laboratory; Twenty healthy men; mean age 21 SD 0.34 were recruited, all subjects performed 200 lengthening contractions of the quadriceps at 120°/s. Isometric and isokinetic peak torque, muscular work, time to peak torque, DOMS and creatine kinase activity were assessed at baseline, 48 h and 96 h post-exercise. The muscle performance was assessed with an isokinetic dynamometer and DOMS with a visual analog scale (VAS). Results: Relative to baseline, isometric and isokinetic peak torque and muscular work decreased in ~30% at 48 h post-exercise; delayed onset muscle soreness increased ~300%, which remained at 96 h post-exercise. Conclusions: These reflect that the decline in muscular performance is due to the changes in peak torque and muscular work, which has greater implications on muscle function. No changes were detected in time to peak torque. The alterations in muscular performance variables are accompanied by delayed onset muscle soreness which has also a negative impact on force production (29% of the drop on peak torque is explain by soreness intensity).

Resumen Introducción: Los estudios de impacto funcional del dolor muscular de aparición tardía (DMAT) se han limitado a describir la disminución de la contracción isométrica máxima, pero aún no se ha examinado el trabajo muscular y el tiempo del torque máximo. Objetivo: Describir los cambios inducidos por una sesión de ejercicio excéntrico sobre el rendimiento muscular y DMAT. Método: se realizó un estudio cuasi-experimental, los participantes fueron veinte hombres sanos; edad media 21 DE 0,34, todos los sujetos realizaron 200 contracciones excéntricas del cuádriceps a 120°/s. Se evaluó el torque pico isométrico e isocinético, el trabajo muscular, el tiempo hasta el torque máximo, DMAT y la actividad de la creatina quinasa al inicio, 48 h y 96 h después del ejercicio, el rendimiento muscular se evaluó con un dinamómetro isocinético y DOMS con una escala análoga visual (EAV). Resultados: en relación con la línea de base, el torque pico isométrico e isocinético y el trabajo muscular disminuyeron en ~ 30 % a las 48 h post-ejercicio; El dolor muscular de aparición tardía aumentó ~300 %, que permaneció 96 h después del ejercicio. Conclusiones: los resultados reflejan que la disminución del rendimiento muscular se debe a los cambios en el torque pico y trabajo muscular, lo que tiene mayores implicaciones en la función muscular. No se detectaron cambios en el tiempo hasta el torque máximo. Las alteraciones en las variables de rendimiento muscular se acompañan de DMAT que también tiene un impacto negativo en la producción de fuerza (el 29 % de la caída en el torque máximo se explica por la intensidad del dolor).

Early hemodynamic profile after aortic valve replacement - a comparison between three mechanical valves

Abstract Introduction: There are scarce data comparing different mechanical valves in the aortic position. The objective of this study was to compare the early hemodynamic changes after aortic valve replacement between ATS, Bicarbon, and On-X mechanical valves. Methods: We included 99 patients who underwent aortic valve replacement with mechanical valves between 2017 and 2019. Three types of mechanical valves were used, On-X valve (n=45), ATS AP360 (n=32), and Bicarbon (n=22). The mean prosthetic valve gradient was measured postoperatively and after six months. Results: Preoperative data were comparable between groups, and there were no differences in preoperative echocardiographic data. Pre-discharge echocardiography showed no difference between groups in the ejection fraction (P=0.748), end-systolic (P=0.764) and end-diastolic (P=0.723) diameters, left ventricular mass index (P=0.348), aortic prosthetic mean pressure gradient (P=0.454), and indexed aortic prosthetic orifice area (P=0.576). There was no difference in the postoperative aortic prosthetic mean pressure gradient between groups when stratified by valve size. The changes in the aortic prosthetic mean pressure gradient of the intraoperative period, at pre-discharge, and at six months were comparable between the three prostheses (P=0.08). Multivariable regression analysis revealed that female gender (beta coefficient -0.242, P=0.027), body surface area (beta coefficient 0.334, P<0.001), and aortic prosthetic size (beta coefficient -0.547, P<0.001), but not the prosthesis type, were independent predictors of postoperative aortic prosthetic mean pressure gradient. Conclusion: The three bileaflet mechanical aortic prostheses (On-X, Bicarbon, and ATS) provide satisfactory early hemodynamics, which are comparable between the three valve types and among different valve sizes.

Effect of Neuromuscular Joint Facilitation Ankle Joint Pattern on Balance in Healthy Young Men / 中国康复理论与实践

Objective:To compare the effects of neuromuscular joint facilitation (NJF) or isotonic muscle training on dynamic and static balance in healthy young men. Methods:October, 2019, twelve students of Capital Medical University School of Rehabilitation Medicine (aged 20 to 29) were evaluated the balance indexes of single leg standing on stable support with eyes closing and single leg standing on unstable support with eyes opening with BIODEX Balance Tester, and measured 10-meter walking time and Timed 'Up and Go' Test (TUGT) after non-intervention, NJF ankle joint pattern and ankle flexion and extension. Results:The balance indexes, 10-meter walking time and TUGT were the least after NJF (F > 18.941, P < 0.01). Conclusion:NJF ankle joint model can improve the dynamic and static balance ability of human body more effectively than isotonic contraction training alone.

Effects of BTE System Intensive Training on Upper Limbs after Cervical Spinal Cord Injury / 中国康复理论与实践

Objective:To investigate the effect of BTE system intensive training on upper limbs for cervical spinal cord injured patients in various courses. Methods:From June, 2019 to January, 2020, 60 inpatients with traumatic C6-7 spinal cord injury were selected into sub-acute group (one to two months after surgery, n = 15), recovery group (three to six months after surgery, n = 15), stable group (over six months after surgery, n = 15) according to the course of disease, and control group (over six months after surgery, n = 15). The control group received comprehensive rehabilitation, while the other groups received upper limbs intensive training on BTE system in addition, for four weeks. They were assessed with Upper Extremity Motor Score (UEMS) and Functional Independence Measure (FIM), meassured isometric peak torque (IPT) and isotonic extreme muscle endurance (IEE) of bilateral elbow extensors before and after treatment. Results:All the indexes improved after treatment (t > 3.500, P < 0.01), and they were significantly different among the groups (F > 9.257, P < 0.001), in which, it was the most of UEMS and IPT in the sub-acute group, and IEE and FIM in the recovery group. Conclusion:BTE system intensive training is effective on upper limbs after cervical spinal cord injury. Sub-acute patients may improve more in motor function and explosive power, while patients at recovery stage do better in endurance and activities of daily living. Even stable patients can benefit from it somehow.

Analysis of Recruitment Pattern of Related Muscles in Two Types of Active Straight Leg Raise / 中国康复理论与实践

Objective:To compare the rate of recruitment in two types of active straight leg raise (ASLR) and to investigate the activation patterns of the related muscles. Methods:From June to October, 2018, eleven healthy subjects were recruited. Surface electromyography (sEMG) signals of unilateral rectus femoris, bilateral rectus abdominis, internal oblique abdominis, external oblique abdominis and multifidus were recorded in normal ASLR (Action A) and raising leg for ten seconds (Action B). %maximal voluntary isometric contraction (MVIC) of these muscles was processed and analyzed. Results:%MVIC of ipsilateral internal oblique muscle and external oblique muscle were greater than the opposite side (t > 2.549, P < 0.05) in Action A; %MVIC of ipsilateral internal oblique muscle, external oblique muscle and rectus abdominis muscle were greater than the opposite side (t > 2.240, P < 0.05) in Action B; compared with action B, Action A had higher %MVIC of bilateral internal oblique and rectus femoris (t > 3.549, P < 0.05). Conclusion:The activation mode of ipsilateral dominance was shown in both actions, and the different motion control strategies may be adopted by the neuromuscular system in different ASLR.

Usage of Traditional and Complementary Medicine among Dengue Fever Patients in the Northeast Region of Peninsular Malaysia

@#Background: The recent epidemic of dengue fever (DF) in Malaysia was alarming. The treatment of DF remains supportive as there is no anti-viral agent or vaccine available as yet. Traditional and complementary medicine (T&CM) provides an alternative option for the treatment of DF but there is limited evidence with regard to its usage. The aim of this study was to determine the prevalence, types and predictor factors of T&CM usage among DF patients in the northeast region of Peninsular Malaysia. Methodology: This was a cross-sectional study of DF patients in the northeast region of Peninsular Malaysia who had been admitted to a tertiary centre from January 2014 until December 2015. Serologically-confirmed DF patients aged 18 years and above were randomly selected. Phone interviews were conducted to obtain information regarding the use of T&CM during hospitalisation. Notes were made regarding the prevalence and type of T&CM used. Binary logistic regressions were used to identify the predictor factors of T&CM usage. Results: A total of 241 DF patients with a mean age of 36.62 (SD = 14.62) years were included. The estimated prevalence of T&CM usage was 84.6% (95%CI: 80.1%, 89.2%). The most common T&CM used were crab soup (85.3%), papaya leaf extract (64.2%) and isotonic drinks (61.8%). The significant predictors for T&CM usage were age [adjusted odds ratio (AOR) 0.97; 95%CI: 0.94, 0.99], tertiary education (AOR 3.86; 95%CI: 1.21, 12.32) and unemployment (AOR 2.55; 95%CI: 1.02, 6.42). Conclusion: The prevalence of T&CM usage in our population is high. Age, tertiary education and unemployment influence the use of T&CM.

A comparative study of acetated isotonic electrolyte solution, normal saline solution, and lactated ringer’s solution in the initial fluid resuscitation of children 1 month to 18 years old with severe dengue at the Philippine Children’s Medical Center

BACKGROUND@#At PCMC, acetated isotonic electrolyte solution is used in the initial resuscitation in severe dengue patients. However, no local study has comparedacetated isotonic electrolyte solution against normal saline and lactated Ringer’s solutions.@*OBJECTIVE@#This study aims to determine the comparative recovery time to achieve initial and sustained cardiovascular stability in severe dengue patients using acetated isotonic electrolyte solution, normal saline solution, and lactated Ringer’s solution.@*METHODOLOGY@#This is a retrospective cohort study involving 166 severe dengue patients 1 month to 18 years old admitted at the PICU from 2014 to 2016. They were divided into 3 groups based on the initial fluid used: 58 in the AIES group, 58 in the NSS group, and 50 in the LRS group.@*RESULTS@#AIES group had the shortest time to achieve initial and sustained stability among patients without re-shock. Also, AIES group needed less fluid to establish stability and had less re-shock, less use of colloid and inotropes, less blood transfusion,and less need for mechanical ventilation and dialysis. NSS had the most fluid shift to AIES and/or colloid while LRS had the most colloid used. Hyperchloremic metabolic acidosis was mostly seen in the NSS group. The length of ICU stay was almost the same in all groups. There was zero mortality in AIES group as compared to 3 on NSS group and 2 in LRS group.@*CONCLUSION AND RECOMMENDATION@#Acetated isotonic electrolyte solution is more effectivethan normal saline and lactated Ringer’s solutions in initial fluid resuscitation among severe dengue patients. It should be the fluid of choice in the initial resuscitation among severe dengue patients. It is recommended that a randomized control study with more patients be conducted.

Comparación entre hidratación con leche chocolatada descremada y bebida deportiva posterior al ejercicio físico en militares / Comparison between hydration with chocolate skim milk and sports drink after physical exercise in militaries

Introducción: dos factores importantes han sido descritos como contribuyentes en la aparición de fatiga durante el ejercicio físico: la disminución de las reservas de glucógeno muscular y la pérdida de agua con electrolitos a través del sudor, que favorecen la deshidratación. Debido a esto, la reposición de líquidos y electrolitos posterior al ejercicio físico se transforma en la prioridad para restablecer la homeostasis corporal alterada durante el ejercicio físico. Por su composición nutricional, la leche parece ser una buena alternativa natural como bebida rehidratante posterior al ejercicio físico. Objetivo: comparar la efectividad como bebida de rehidratación de la leche descremada chocolatada contra una bebida deportiva artificial en militares, a partir de la hipótesis de que la leche descremada chocolatada tiene iguales o mejores efectos sobre la hidratación post ejercicio, que una bebida deportiva artificial. Método: 30 militares (23,0 ± 3,2 años) se dividieron en 2 grupos: 1) rehidratación con bebida deportiva con 6 pòr ciento de carbohidratos y relación de Na/K 2:1 (grupo ISO). Rehidratación con leche descremada chocolatada (grupo LECHE). Se evaluó la retención de fluidos a través del peso corporal y la gravedad específica de la orina (GEO) antes y después del ejercicio físico y posterior a las 2 horas de rehidratación. Resultados: se encontraron diferencias significativas (p< 0,05) en la retención de fluidos en el grupo LECHE comparado con el grupo ISO. No hubo diferencias significativas entre la GEO de ambos grupos. Conclusión: Los resultados muestran que la rehidratación con leche descremada es más efectiva en la retención de fluidos y recuperación del peso previo al ejercicio que la bebida deportiva(AU)

ntroduction: Two important factors have been described as contributing to the onset of fatigue during physical exercise: Decreased muscle glycogen stores and the loss of water with electrolytes through sweating, favoring dehydration. Because of this, fluid and electrolyte replacement after physical exercise becomes the priority to restore altered body homeostasis during physical exercise. Due to its nutritional composition, milk appears to be a good natural alternative as a rehydration beverage after exercise. Objective: To compare the effectiveness chocolate skim milk as pots-exercise rehydration beverage with an artificial sports drink in the military, based on the hypothesis that chocolate skim milk has equal or better effects on post-exercise hydration than an artificial sports drink. Method: 30 soldiers (23.0 ± 3.2 years) were divided into 2 groups: 1) rehydration with sports drink with 6 percent carbohydrates and ratio of Na / K 2: 1 (ISO group). Rehydration with chocolate skim milk (LECHE group). Fluid retention was assessed through body weight and the specific gravity of urine (GEO) before and after physical exercise and after 2 hours of rehydration. Results: significant differences were found (p < 0.05) in fluid retention in the LECHE group compared to the ISO group. There were no significant differences between the GEO of both groups. Conclusion: The results show that rehydration with skim milk is more effective in fluid retention and weight recovery prior to exercise than sports drink(AU)

Acute effect of different stretching methods on the strength performance in successive series / Efeito agudo de diferentes métodos de alongamento sobre o desempenho da força em séries sucessivas

ABSTRACT There is still no consensus about the use of stretching before strength exercises in successive series. Thus, the aim was to verify the acute effect of two stretching methods on the strength performance in the bench press exercise. Trained subjects performed 3 sets of 8 to10-RM in the bench press immediately after the static stretching (SS), Proprioceptive Neuromuscular Facilitation (PNF) or control condition. There was a significant decrease in repetitions in the second and third series compared to the first for all conditions. There was no significant difference in the number of repetitions or total volume between the conditions with and without stretching. The SS and PNF induced no negative effect on strength performance and can be used prior to this exercise

RESUMO Ainda não há consenso sobre a utilização de alongamentos antes de exercícios de força em séries sucessivas. Sendo assim, o objetivo foi verificar o efeito agudo de dois métodos de alongamento sobre o desempenho da força no exercício supino reto. Indivíduos treinados realizaram 3 séries de 8 a 10-RM no supino reto imediatamente após o alongamento estático (AE), Facilitação Neuromuscular Proprioceptiva (FNP) ou condição controle. Foi encontrada queda significativa das repetições na segunda e terceira séries em comparação à primeira em todas as condições. Não houve diferença significativa no número de repetições ou no volume total entre as condições com e sem alongamento. O AE e a FNP não causaram impacto negativo no desempenho da força, podendo, assim, serem utilizados previamente a esse exercício.

Solução salina versus solução de heparina na perviedade do cateter venoso periférico na terapia venosa intermitente: revisão sistemática / Saline solution versus heparin in the patency of the venous peripheral catheter in the intermittent venous therapy: a systematic review

O uso do cateter venoso periférico intermitente em pacientes hospitalizados pode lhes trazer grandes benefícios, proporcionando maior liberdade com a higiene pessoal, alimentação, deambulação, além melhorias para a equipe de enfermagem com redução das rotinas diárias. No entanto, obstrução do cateter é algo que vem na contramão de uma assistência adequada, causando desconforto para o paciente e aumento do trabalho de enfermagem. Para evitar tal evento e garantir a perviedade do cateter intravascular, deve-se realizar o flushing com solução salina ou solução de heparina, após a administração de medicamentos ou em horários programados de acordo com o protocolo interno das instituições de saúde. Nesse contexto, surge o questionamento de qual é a melhor solução para manter a perviedade do cateter venoso periférico intermitente. Este estudo trata-se de uma revisão sistemática da literatura, com o objetivo de avaliar a efetividade do uso da solução salina comparada à solução de heparina na manutenção da perviedade dos cateteres venosos periféricos. Foi realizada a busca nas bases de dados eletrônicas Cinahl, Cochrane Central, Embase, Lilacs, Pubmed e Web of Science. Das 372 referências identificadas, 12 estudos foram selecionados após a análise de título e resumo para serem lidos na íntegra, sendo que 04 constituíram a amostra final. A extração e análise dos dados foram realizadas por dois revisores independentes e as divergências entre eles foram solucionadas por um terceiro revisor. Os 04 estudos foram publicados no período de 1995 a 2015. Ao todo, foram investigados 975 dispositivos endovenosos mantidos com uma das soluções estudadas em 420 participantes. Os estudos testaram a solução de heparina em dosagens que variaram de 10UI/mL a 100UI/mL versus a solução salina e investigaram as complicações relacionadas ao cateter venoso periférico em uso intermitente, sendo uma delas a obstrução do cateter a qual denominamos como ausência e/ou diminuição da perviedade do cateter venoso, que pode ser evitada com o flushing de forma adequada. As intervenções foram testadas em diferentes populações e não foram concordantes em suas conclusões; dois estudos recomendaram a solução de heparina, um estudo, a solução salina, e um recomenda o uso das duas soluções. Os quatro estudos discutem que as duas soluções são seguras e eficazes para a manutenção da perviedade do cateter venoso periférico. Porém, os autores afirmam que o tamanho da amostra não é suficiente para generalizar os resultados para todos os pacientes hospitalizados. Assim, essa revisão sistemática sugere a necessidade de que novos ensaios clínicos randomizados sejam realizados e que as instituições de saúde devem fomentar as investigações clínicas para validar uma assistência de enfermagem alicerçada em práticas seguras e de qualidade

The using of intermittent peripheral venous catheter in a hospitalized patient can bring to them important benefits, providing more freedom concerning to the personal hygiene, feeding, ambulation, and a lot of another improvements for the nursing team, reducing the daily routines. However, catheter obstruction it is something that disturb an appropriate assistence, provoking discomfort to the patient and increasing the need of job of the nursing team. To avoid this fact and to ensure the patency of the intervascular catheter, must to do the flushing process with saline solution or hepamin, after the application of drugs or in pre established time according to the protocol of procedure of the health institutions. In this regard, it emerges the questioning about what is the best solution to keep the patency of the intermittent peripheral venous catheter. This research is a systematic review about the litetature on this subject, and it aims to evaluate the effectiveness of the using of the saline solution in comparison to the heparin in the maintenance of the patency of the peripheral venous catheter. It has been done a research in the electronic databases Cinahl, Cochrane Central, Embase, Lilacs, Pubmed and Web of Science. An amount of 372 references was identified, but just 12 research were selected after the analysis of their titles and abstracts to be fully read. In the end, 04 of them were picked as definitive samples.The data collect and the anlysis were done by two independent reviewers, and the divergences between them were solved by a third reviewer. The 04 research were publicized in the 1995 to 2015 period. Altogheter, were searched 975 intravenous devices, keeping them with one of the studied solutions in 420 patients. Th estudies tried the heparin in dosages that vary from 10UI/mL to 100UI/mL versus the saline solution and investigated the complications related to the peripheral venous catheter in a intermittent using. One of these complications was the catheter obstruction, wich were designated as lack or the decrease of the patency of the venous catheter, that can be avoided with an appropriate flushing process. The interventions were tried in different populations, and they were not concordant in their conclusions. Two research recommended the heparin, one, the saline solution, and one of them recommend to use both. The four research affirm that the heparin and the saline solution are safety and effective for the maintenance of the patency of the peripheral venous catheter. However, the authors say point out that the quantity of the simple is not enough to to generalize the results regarding to all hospitalized patients. Thus, this systematic review suggest the necessity of new randomized clinical testings. In addition, the health institutions must promote clinical research in order to validate a solid nursing assistance based on safety and appropriated practices

Fluidoterapia para la prevención de hipotensión arterial secundaria a anestesia espinal en operación cesárea: ¿Tenemos todas las respuestas? / Fluid therapy preventing arterial hypotension after spinal anesthesia for cesarean section: do we have all the answers?

Spinal anesthesia is the technique of choice for patients undergoing cesarean section. One of the most common adverse effects of this technique is arterial hypotension, which if severe, can result in serious maternal and fetal injury or death. Different alternatives exist to prevent and treat hypotension associated to spinal anesthesia; one of them is fluid therapy. The objective of this review is to evaluate the currently available evidence for different fluid therapy alternatives and assess their effectiveness. Nowadays, it does not seem advisable to use preload with crystalloids as evidence suggests its ineffectiveness. As for the other three alternatives (preload with colloids, coload with crystalloids and coload with colloids) there is no superiority among them and neither of them seems effective enough to be used as monotherapy. Due to its safety and ease of use, coload with crystalloids associated to alpha agonist vasopressor therapy seems to be the best management strategy. Further studies should aim at the best way to administer fluids in order to optimize vasopressor therapy.

La técnica anestésica de elección para operación cesárea es la anestesia subaracnoídea. Uno de los principales efectos adversos de esta técnica es la hipotensión arterial, que puede llegar a ocasionar graves complicaciones. Existen diversas alternativas para la prevención y manejo de la hipotensión arterial; una de ellas la fluidoterapia. El objetivo de esta revisión es evaluar la evidencia reciente disponible para las distintas alternativas de fluidoterapia y evaluar su efectividad. Actualmente no parece recomendable el utilizar precarga con cristaloides para la prevención de hipotensión arterial. En cuanto a las otras tres alternativas(precarga con coloides, cocarga con cristaloides o cocarga coloides) ninguna parece ser más efectiva que las otras previniendo hipotensión arterial y ninguna sería efectiva como monoterapia. Por su disponibilidad y seguridad de uso, al día de hoy la cocarga con cristaloides asociada a terapia vasopresora alfa agonista parece ser la mejor alternativa. Estudios futuros debieran apuntar a encontrar la forma de infusión que optimize la terapia con vasopresores.

Foi realizada a busca nas bases de dados eletrônicas Cinahl, Cochrane Central, Embase, Lilacs, Pubmed e Web of Science. Das 372 referências identificadas, 12 estudos foram selecionados após a análise de título e resumo para serem lidos na íntegra, sendo que 04 constituíram a amostra final. A extração e análise dos dados foram realizadas por dois revisores independentes e as divergências entre eles foram solucionadas por um terceiro revisor. Os 04 estudos foram publicados no período de 1995 a 2015. Ao todo, foram investigados 975 dispositivos endovenosos mantidos com uma das soluções estudadas em 420 participantes. Os estudos testaram a solução de heparina em dosagens que variaram de 10UI/mL a 100UI/mL versus a solução salina e investigaram as complicações relacionadas ao cateter venoso periférico em uso intermitente, sendo uma delas a obstrução do cateter a qual denominamos como ausência e/ou diminuição da perviedade do cateter venoso, que pode ser evitada com o flushing de forma adequada. As intervenções foram testadas em diferentes populações e não foram concordantes em suas conclusões; dois estudos recomendaram a solução de heparina, um estudo, a solução salina, e um recomenda o uso das duas soluções. Os quatro estudos discutem que as duas soluções são seguras e eficazes para a manutenção da perviedade do cateter venoso periférico. Porém, os autores afirmam que o tamanho da amostra não é suficiente para generalizar os resultados para todos os pacientes hospitalizados. Assim, essa revisão sistemática sugere a necessidade de que novos ensaios clínicos randomizados sejam realizados e que as instituições de saúde devem fomentar as investigações clínicas para validar uma assistência de enfermagem alicerçada em práticas seguras e de qualidade

The using of intermittent peripheral venous catheter in a hospitalized patient can bring to them important benefits, providing more freedom concerning to the personal hygiene, feeding, ambulation, and a lot of another improvements for the nursing team, reducing the daily routines. However, catheter obstruction it is something that disturb an appropriate assistence, provoking discomfort to the patient and increasing the need of job of the nursing team. To avoid this fact and to ensure the patency of the intervascular catheter, must to do the flushing process with saline solution or hepamin, after the application of drugs or in pre established time according to the protocol of procedure of the health institutions. In this regard, it emerges the questioning about what is the best solution to keep the patency of the intermittent peripheral venous catheter. This research is a systematic review about the litetature on this subject, and it aims to evaluate the effectiveness of the using of the saline solution in comparison to the heparin in the maintenance of the patency of the peripheral venous catheter. It has been done a research in the electronic databases Cinahl, Cochrane Central, Embase, Lilacs, Pubmed and Web of Science. An amount of 372 references was identified, but just 12 research were selected after the analysis of their titles and abstracts to be fully read. In the end, 04 of them were picked as definitive samples.The data collect and the anlysis were done by two independent reviewers, and the divergences between them were solved by a third reviewer. The 04 research were publicized in the 1995 to 2015 period. Altogheter, were searched 975 intravenous devices, keeping them with one of the studied solutions in 420 patients. Th estudies tried the heparin in dosages that vary from 10UI/mL to 100UI/mL versus the saline solution and investigated the complications related to the peripheral venous catheter in a intermittent using. One of these complications was the catheter obstruction, wich were designated as lack or the decrease of the patency of the venous catheter, that can be avoided with an appropriate flushing process. The interventions were tried in different populations, and they were not concordant in their conclusions. Two research recommended the heparin, one, the saline solution, and one of them recommend to use both. The four research affirm that the heparin and the saline solution are safety and effective for the maintenance of the patency of the peripheral venous catheter. However, the authors say point out that the quantity of the simple is not enough to to generalize the results regarding to all hospitalized patients. Thus, this systematic review suggest the necessity of new randomized clinical testings. In addition, the health institutions must promote clinical research in order to validate a solid nursing assistance based on safety and appropriated practices

Cristaloides balanceados para ressuscitação do choque séptico / Balanced crystalloids for septic shock resuscitation

RESUMO A administração de fluidos em tempo adequado é crucial para a manutenção da perfusão tissular nos pacientes com choque séptico. Entretanto, a questão da escolha do fluido a ser utilizado para ressuscitação no choque séptico ainda é um assunto em debate. É crescente o corpo de evidência que sugere que o tipo, a quantidade e o momento da administração de fluidos durante a evolução da sepse podem afetar os desfechos do paciente. Os cristaloides têm sido recomendados como fluidos a serem administrados em primeira linha na ressuscitação do choque. No entanto, à luz da natureza inconclusiva da literatura disponível, não se podem fazer recomendações definitivas quanto à solução cristaloide mais apropriada. A ressuscitação de pacientes críticos sépticos e não sépticos com cristaloides não balanceados, principalmente a solução salina a 0,9%, tem sido associada a uma maior incidência de desordens do equilíbrio ácido-base e a distúrbios eletrolíticos, além de poder se associar à maior incidência de lesão renal aguda, à maior necessidade de terapia de substituição renal e à mortalidade. Foi proposto o uso de soluções cristaloides balanceadas como uma alternativa às soluções de cristaloides não balanceados, para mitigar seus efeitos deletérios. Entretanto, a segurança e a eficácia dos cristaloides balanceados para ressuscitação do choque séptico necessitam ser mais bem exploradas em estudos clínicos bem delineados, randomizados e controlados, multicêntricos e pragmáticos.

ABSTRACT Timely fluid administration is crucial to maintain tissue perfusion in septic shock patients. However, the question concerning which fluid should be used for septic shock resuscitation remains a matter of debate. A growing body of evidence suggests that the type, amount and timing of fluid administration during the course of sepsis may affect patient outcomes. Crystalloids have been recommended as the first-line fluids for septic shock resuscitation. Nevertheless, given the inconclusive nature of the available literature, no definitive recommendations about the most appropriate crystalloid solution can be made. Resuscitation of septic and non-septic critically ill patients with unbalanced crystalloids, mainly 0.9% saline, has been associated with a higher incidence of acid-base balance and electrolyte disorders and might be associated with a higher incidence of acute kidney injury. This can result in greater demand for renal replacement therapy and increased mortality. Balanced crystalloids have been proposed as an alternative to unbalanced solutions in order to mitigate their detrimental effects. Nevertheless, the safety and effectiveness of balanced crystalloids for septic shock resuscitation need to be further addressed in a well-designed, multicenter, pragmatic, randomized controlled trial.

Effects of intracutaneous injections of sterile water in patients with acute low back pain: a randomized, controlled, clinical trial

Intracutaneous sterile water injection (ISWI) is used for relief of low back pain during labor, acute attacks of urolithiasis, chronic neck and shoulder pain following whiplash injuries, and chronic myofascial pain syndrome. We conducted a randomized, double-blinded, placebo-controlled trial to evaluate the effect of ISWI for relief of acute low back pain (aLBP). A total of 68 patients (41 females and 27 males) between 18 and 55 years old experiencing aLBP with moderate to severe pain (scores ≥5 on an 11-point visual analogue scale [VAS]) were recruited and randomly assigned to receive either ISWIs (n=34) or intracutaneous isotonic saline injections (placebo treatment; n=34). The primary outcome was improvement in pain intensity using the VAS at 10, 45, and 90 min and 1 day after treatment. The secondary outcome was functional improvement, which was assessed using the Patient-Specific Functional Scale (PSFS) 1 day after treatment. The mean VAS score was significantly lower in the ISWI group than in the control group at 10, 45, and 90 min, and 1 day after injection (P<0.05, t-test). The mean increment in PSFS score of the ISWI group was 2.9±2.2 1 day after treatment, while that in the control group was 0.9±2.2. Our study showed that ISWI was effective for relieving pain and improving function in aLBP patients at short-term follow-up. ISWI might be an alternative treatment for aLBP patients, especially in areas where medications are not available, as well as in specific patients (e.g., those who are pregnant or have asthma), who are unable to receive medications or other forms of analgesia because of side effects.

Calculation of the Residual Blood Volume after Acute, Non-Ongoing Hemorrhage Using Serial Hematocrit Measurements and the Volume of Isotonic Fluid Infused: Theoretical Hypothesis Generating Study

Fluid resuscitation, hemostasis, and transfusion is essential in care of hemorrhagic shock. Although estimation of the residual blood volume is crucial, the standard measuring methods are impractical or unsafe. Vital signs, central venous or pulmonary artery pressures are inaccurate. We hypothesized that the residual blood volume for acute, non-ongoing hemorrhage was calculable using serial hematocrit measurements and the volume of isotonic solution infused. Blood volume is the sum of volumes of red blood cells and plasma. For acute, non-ongoing hemorrhage, red blood cell volume would not change. A certain portion of the isotonic fluid would increase plasma volume. Mathematically, we suggest that the residual blood volume after acute, non-ongoing hemorrhage might be calculated as 0·25N/[(Hct1/Hct2)-1], where Hct1 and Hct2 are the initial and subsequent hematocrits, respectively, and N is the volume of isotonic solution infused. In vivo validation and modification is needed before clinical application of this model.

Comparison of two maintenance electrolyte solutions in children in the postoperative appendectomy period: a randomized, controlled trial / Comparação de duas soluções para manutenção hidroeletrolítica no pós-operatório de apendicectomia em crianças: um estudo controlado e randomizado

ABSTRACT OBJECTIVE: To compare two electrolyte maintenance solutions in the postoperative period in children undergoing appendectomy, in relation to the occurrence of hyponatremia and water retention. METHODS: A randomized clinical study involving 50 pediatric patients undergoing appendectomy, who were randomized to receive 2,000 mL/m2/day of isotonic (Na 150 mEq/L or 0.9% NaCl) or hypotonic (Na 30 mEq/L NaCl or 0.18%) solution. Electrolytes, glucose, urea, and creatinine were measured at baseline, 24 h, and 48 h after surgery. Volume infused, diuresis, weight, and water balance were analyzed. RESULTS: Twenty-four patients had initial hyponatremia; in this group, 13 received hypotonic solution. Seventeen patients remained hyponatremic 48 h after surgery, of whom ten had received hypotonic solution. In both groups, sodium levels increased at 24 h (137.4 ± 2.2 and 137.0 ± 2.7 mmol/L), with no significant difference between them (p = 0.593). Sodium levels 48 h after surgery were 136.6 ± 2.7 and 136.2 ± 2.3 mmol/L in isotonic and hypotonic groups, respectively, with no significant difference. The infused volume and urine output did not differ between groups during the study. The water balance was higher in the period before surgery in patients who received hypotonic solution (p = 0.021). CONCLUSIONS: In the post-appendectomy period, the use of hypotonic solution (30 mEq/L, 0.18%) did not increase the risk of hyponatremia when compared to isotonic saline. The use of isotonic solution (150 mEq/L, 0.9%) did not favor hypernatremia in these patients. Children who received hypotonic solution showed higher cumulative fluid balance in the preoperative period.

RESUMO OBJETIVO: Comparar duas soluções de manutenção hidroeletrolítica no período pós-operatório (PO) de crianças submetidas à apendicectomia quanto à ocorrência de hiponatremia e retenção hídrica. MÉTODOS: Estudo clínico randomizado que envolveu 50 pacientes pediátricos submetidos à apendicectomia, randomizados para receber 2.000 ml/m2/dia de solução isotônica (Na 150 mEq/L ou NaCl 0,9%) ou hipotônica (Na 30mEq/L ou NaCl 0,18%). Eletrólitos, glicose, ureia e creatinina foram mensurados no início do estudo, 24 e 48 horas após a cirurgia. Foram analisados volume infundido, diurese, peso e balanço hídrico. RESULTADOS: Apresentaram hiponatremia inicial 24 pacientes. Desses, 13 receberam solução hipotônica. Dezessete pacientes permaneceram hiponatrêmicas 48 horas após a cirurgia, 10 haviam recebido solução hipotônica. Nos dois grupos os níveis de sódio aumentaram na 24ª hora PO (137,4 ± 2,2 e 137,0 ± 2,7) e não houve diferença entre eles (p = 0,593). Níveis de sódio 48 h após a cirurgia foram 136,6 ± 2,7 e 136,2 ± 2,3 no grupo isotônico e hipotônico respectivamente sem diferença significativa. Os volumes infundidos e a diurese não diferiram entre os grupos durante o estudo. O balanço hídrico foi maior no período anterior à cirurgia no grupo de pacientes que receberam solução hipotônica (p = 0,021). CONCLUSÕES: No período pós-apendicectomia, o uso da solução hipotônica não aumentou o risco de hiponatremia quando comparado com uma solução salina isotônica. O uso da solução isotônica não favoreceu a hipernatremia nesses pacientes. Crianças que receberam solução hipotônica apresentaram maior balanço hídrico cumulativo no período pré-operatório.
