Local Anaesthetics Combined with Vasoconstrictors in Controlled Hypertensive Patients Undergoing Dental Procedures: Systematic Review and Meta-Analysis / Uso de Anestésicos Locales con Vasoconstrictor en Pacientes con Hipertensión Controlada Durante la Atención Odontológica: Una Revisión Sistemática y Metaanálisis

The aim of this systematic review is to assess the safety of local anaesthetics (LA) combined with vasoconstrictors (VC) for patients with controlled hypertension undergoing dental procedures. A comprehensive search strategy were used to identify all relevant randomized controlled trials (RCTs) that evaluated the effect of LA combined with VC. All searches covered the period from 1990 to February 2021. We performed a meta-analysis using random-effect models and assessed overall certainty in evidence using GRADE approach. Our search strategy yielded 1262 references. Finally, seven randomised trials were included, but only three were included in the meta-analysis. The use of LA with VC may result in little to no difference in the heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP), but the certainty of the evidence was assessed as low. Death, stroke, acute myocardial infarction, need for hospitalization, pain and bleeding were not reported by the included studies. The hemodynamic changes using VC do not imply an increased risk of occurrence of adverse cardiovascular events. The use of VC could even be recommendable considering their multiple advantages.

El objetivo de esta revisión sistemática es evaluar la seguridad del uso de anestésicos locales (AL) combinados con vasoconstrictor (VC) en pacientes con hipertensión controlada durante procedimientos dentales. Se realizó una estrategia de búsqueda para identificar todos los estudios clínicos aleatorizados (ECA) relevantes que evaluaban el efecto del AL combinado con VC. Todos los estudios fueron del periodo entre 1990 a febrero del 2021. Se realizó un meta-análisis usando modelos de efecto aleatorizado y una revisión de la certeza de la evidencia usando el método GRADE. Nuestra estrategia de búsqueda arrojó 1262 referencias. Finalmente, siete estudios clínicos aleatorizados fueron incluidos, de los cuales tres fueron incluidos en el meta-análisis. El uso de AL con VC produce una pequeña a ninguna diferencia en el pulso cardiaco, presión sistólica y diastólica, pero la certeza de la evidencia fue baja. Muerte, infarto agudo al miocardio, accidente cerebrovascular, necesidad de hospitalización, dolor y hemorragia no fueron reportados en los estudios incluidos. Los cambios hemodinámicos en el uso de VC no implican un aumento de riesgo de ocurrencia de efectos adversos cardiovasculares. El uso de VC puede ser recomendable considerando sus múltiples ventajas.

Retrospective study on the use of epinephrine in patients with drug-induced anaphylactic shock in Chongqing from 2015 to 2022 / 中国药房

OBJECTIVE To evaluate the rationality of epinephrine in the treatment of drug-induced anaphylactic shock， and to provide a reference for further standardizing the treatment measures of anaphylactic shock. METHODS According to the relevant data of the reports of severe adverse drug reaction （ADR） of drug-induced anaphylactic shock provided by Chongqing ADR Monitoring Center from 2015 to 2022， the selection of treatment drugs， and the application of epinephrine in anaphylactic shock were analyzed retrospectively； the clinical outcomes of anaphylactic shock with different epinephrine administration methods were investigated. RESULTS A total of 1 415 cases of severe ADR related to drug-induced anaphylactic shock were reported， with a male-to-female ratio of 1.04∶1； the drugs that caused allergic shock mainly included anti-infective drugs （47.92%）， TCM injections （9.12%）； the patients who suffered from drug-induced anaphylactic shock within 10 min after medication accounted for 43.96%； 97.24% of patients were cured or improved， and 2.76% of patients died or did not been improved. Among 1 415 patients， 63.39% of patients were treated with epinephrine， and the patients who preferred epinephrine treatment accounted for 53.14%； the intramuscular injection， subcutaneous injection， intravenous injection and intravenous drip accounted for 33.78%， 30.32%， 25.75% and 1.23%， respectively. The initial dose range of epinephrine was 0.01-10 mg， and the most frequent single dose was 1 mg （44.70%）. Excessive single doses of intramuscular injection， subcutaneous injection and intravenous injection accounted for 51.03% （148 cases）， 53.13% （136 cases） and 91.47% （193 cases） respectively， and the risk of overdose in intravenous injection was higher （P＜0.05）. The patients receiving initial treatment with epinephrine had a higher improvement rate/cure rate than those who did not use epinephrine （98.14% vs. 96.23%， P＝0.029）； the patients who preferred epinephrine had a higher improvement rate/cure rate than those who did not preferred epinephrine （98.14% vs. 95.17%， P＝0.031）； the improvement rate/cure rate of patients receiving intramuscular injection of epinephrine was higher than those without intramuscular injection （99.01% vs. 96.69%， P＝0.038）. CONCLUSIONS There are some unreasonable phenomena in the treatment of drug-induced anaphylactic shock， such as inappropriate selection of drugs， insufficient use of epinephrine， delay of administration， inappropriate route of administration and excessive single dose.

Favorable Safety Experience of Local Dental Anesthesia in ICD Recipients with Cardiac Channelopathies

Abstract Background Dental anesthetic management in implantable cardioverter defibrillator (ICD) recipients with cardiac channelopathies (CCh) can be challenging due to the potential risk of life-threatening arrhythmias and appropriate ICD therapies during procedural time. Objectives The present study assessed the hypothesis that the use of local dental anesthesia with 2% lidocaine with 1:100,000 epinephrine or without a vasoconstrictor can be safe in selected ICD and CCh patients, not resulting in life-threatening events (LTE). Methods Restorative dental treatment under local dental anesthesia was made in two sessions, with a wash-out period of 7 days (cross-over trial), conducting with a 28h - Holter monitoring, and 12-lead electrocardiography, digital sphygmomanometry, and anxiety scale assessments in 3 time periods. Statistical analysis carried out the paired Student's t test and the Wilcoxon signed-rank test. In all cases, a significance level of 5% was adopted. All patients were in stable condition with no recent events before dental care. Results Twenty-four consecutive procedures were performed in 12 patients (9 women, 3 men) with CCh and ICD: 7 (58.3%) had long QT syndrome (LQTS), 4 (33.3%) Brugada syndrome (BrS), and 1 (8.3%) Catecholaminergic polymorphic ventricular tachycardia (CPVT). Holter analysis showed no increased heart rate (HR) or sustained arrhythmias. Blood pressure (BP), electrocardiographic changes and anxiety measurement showed no statistically significant differences. No LTE occurred during dental treatment, regardless of the type of anesthesia. Conclusion Lidocaine administration, with or without epinephrine, can be safely used in selected CCh-ICD patients without LTE. These preliminary findings need to be confirmed in a larger population with ICD and CCh.

A prospective, comparative study of the analgesic effect between the WALANT technique and local anesthesia associated with sedation for hand surgery

Purpose: The primary objective of this study was to compare the WALANT (wide awake, local anesthesia, no tourniquet) technique with local anesthesia associated with sedation in relation to pain intensity for minor hand surgical procedures. The secondary objective was to evaluate the need for analgesic complementation. Methods: A prospective, randomized, comparative, and clinical study was carried out. The sample size in each group was determined after statistical evaluation of the results of a pilot project. The participants were allocated to one of two groups; those in group 1 were submitted to the WALANT technique, and those in group 2, to local anesthesia associated with sedation, for elective surgery. The surgical procedures were carpal tunnel syndrome, De Quervain's tenosynovitis, synovial cyst, finger cyst, and trigger finger. Pain intensity, need for complementation and evolution to complex regional pain syndrome were evaluated. Results: There was no difference between groups in pain intensity after WALANT and need for intraoperative complementation. There was no significant difference in the amount of opioid applied postoperatively between the groups. There was no difference between groups regarding comfort during surgery. There was no difference in adverse effects and complications between the groups. Hematoma was the most frequent adverse event. No severe adverse events were observed. Conclusions: The WALANT technique promoted an analgesic effect similar to that of local anesthesia associated with sedation, without increasing adverse effects.

Avaliação dos padrões cardiovasculares e da concentração sérica de catecolaminas em pacientes submetidos à exodontias por via alveolar, sob anestesia local com epinefrina: um ensaio clínico controlado, cego e randomizado / Assessment of cardiovascular patterns and serum catecholamine concentration in patients undergoing alveolar extraction under local anesthesia with epinephrine: a controlled, blind and randomized clinical trial

Objetivos: Um ensaio clínico controlado, cego e randomizado foi desenvolvido para avaliar os efeitos cardiovasculares em pacientes saudáveis e com hipertensão submetidos à exodontia por via alveolar utilizando lidocaína com epinefrina 1:100.000. Materiais e métodos: Vinte pacientes foram divididos em grupos experimental (GE ­ pacientes hipertensos) e controle (GC ­ pacientes normotensos). As variáveis analisadas foram a frequência cardíaca (FC), saturação de oxigênio (SO2), pressão arterial sistólica e diastólica (PAsis e PAdias), concentração sérica de catecolaminas (dopamina, epinefrina e norepinefrina), extrassístoles ventriculares e supraventriculares (ESV e ESSV respectivamente) e depressão do segmento do ST. Os dados foram colhidos em três momentos distintos: inicial, transoperatório (trans) e final. Amostras de sangue foram coletadas para a mensuração das catecolaminas, e um aparelho de Holter foi utilizado para coleta de dados do eletrocardiograma incluindo um período de avaliação de 24 horas pós-operatório. Foram utilizados o teste de Mann-Whitney para identificar diferenças entre os grupos e o teste de Friedman com o pós-teste de Wilcoxon ajustado para a avaliação intragrupos das amostras repetidas. Resultados: O GE apresentou menor SO2 no momento inicial (p = 0,001) enquanto a PAsis apresentou diferença estatística para os três momentos de avaliação com o GE apresentando os maiores valores. As ESV foram maiores para o GE no período de avaliação pós-operatória de 24 horas (p = 0,041). As ESSV e as catecolaminas séricas foram similares nos dois grupos. A análise intragrupo revelou diferença significativa na avaliação da PAsis para o GE com o período trans operatório apresentando os maiores valores. Já avaliação das extrassístoles demonstrou que o período pós-operatório de 24 horas teve a maioria dos eventos sendo que apenas o GC não apresentou diferença significativa para a variável ESV durante esse período (p = 0,112). Não houve depressão do segmento ST para nenhum dos grupos, ou seja, a isquemia do miocárdio não foi observada durante o estudo. Conclusões: As exodontias por via alveolar, com o uso de ALVC com epinefrina podem ser realizadas de forma segura em pacientes hipertensos. A pressão arterial sistêmica deve ser monitorada durante todo o procedimento, sobretudo nos pacientes hipertensos, devido à tendência de aumento da pressão arterial nesses pacientes. Já o nível sérico de catecolaminas não sofre alteração nas condições estudadas assim como o uso de ALVC parecem não influenciar os padrões cardiovasculares nesse tipo de cirurgia (AU).

Objectives: A blind, randomized controlled clinical trial was developed to evaluate the cardiovascular effects of local anesthetics with vasoconstrictors (LAVC) containing epinephrine in healthy and hypertensive patients undergoing teeth extraction with lidocaine 2% with epinephrine 1:100.000. Materials and methods: 20 patients were divided into control (CG ­ normotensive patients) and experimental groups (EG ­ hypertensive patients). The variables analyzed were heart rate (HR), oxygen saturation (O2S), systolic and diastolic blood pressure (sysBP and diasBP), serum catecholamines concentration (dopamine, epinephrine, and norepinephrine), ventricular and supraventricular extrasystoles (VES and SVES respectively), and ST segment depression. Data was obtained in three different moments (initial, trans and final). Blood samples were taken to measure the catecholamines and a Holter device was used to measure data from the electrocardiogram including a 24-hour postoperative evaluation period. The Mann-Whitney test was used to identify differences between the two groups and the Friedman test with the adjusted Wilcoxon post-test were used for intragroup evaluation for repeated measures. Results: The EG presented a lower O2S in the initial period (p = 0,001) while the sysBP showed a statistical difference for the three evaluation periods with the EG presenting the highest values. The VES where higher for the EG during the 24-hour postoperative evaluation period (p = 0,041). The SVES and the serum catecholamines showed were similar between the groups. The intragroup analysis revealed significant statistical difference for the sysBP in the EG with the trans period presenting the highest measurements. The extrasystoles evaluation showed that the 24- hour postoperative period presented most events with only the CG not presenting statistical difference for the variable VES during this period (p = 0,112). No ST segment depression was noticed for both groups, ie, Myocardial ischemia was not observed. Conclusions: Teeth extraction with LAVC containing epinephrine can be safely executed in hypertensive patients. Blood pressure should be monitored during the entire procedure, especially in hypertensive patients due to a tendency to high blood pressure within these patients. Serum catecholamines concentration levels are not altered in the conditions seen in this study and the use of LAVC seem not to influence cardiovascular changes in this type of surgery (AU).

El auge y la caída del mito de la epinefrina en la mano / The Rise and Fall of the Epinephrine Myth in the Hand

La posibilidad de operar a los pacientes con afecciones de la mano bajo anestesia local con la lidocaína y la epinefrina usando la técnica WALANT provocó una revolución en la cirugía de la mano, que facilitó la vida de los pacientes y disminuyó los costos de los servicios hospitalarios. Es necesario que los cirujanos conozcan la técnica y la historia de esta técnica. El objetivo fue identificar los orígenes del auge y la caída del mito y del dogma de la prohibición de la adrenalina en los bloqueos anestésicos de los dedos. Se realizó un análisis crítico de los principales textos de los artículos y los libros sobre el uso de la epinefrina en la anestesia de los dedos. La creación del mito de prohibir el uso de la epinefrina en los bloqueos anestésicos de los dedos se produjo debido a la mala interpretación de los informes de los casos de necrosis ocurridos que, en realidad, no fueron causados por la epinefrina. Ese mito influyó en la aparición de un dogma. La historia del uso de la epinefrina en los bloqueos de los dedos anestésicos demuestra que las interpretaciones superficiales y erróneas de las complicaciones clínicas publicadas como informes de casos pueden generar mitos y dogmas. Solo la ciencia puede prevenir y destruir tales mitos y dogmas médicos(AU)

The possibility of operating patients with hand conditions under local anesthesia, with lidocaine and epinephrine, using WALANT technique caused a revolution in hand surgery, which made life easier for patients and lowered the costs of hospital services. Surgeons need to be aware of the possibilities and history of WALANT technique. The objective was to identify the origins of the rise and fall of the myth and dogma of the prohibition of adrenaline in anesthetic finger blocks. A critical analysis of the main texts of the articles and books on the use of epinephrine in finger anesthesia was carried out. The conception of the myth of banning the use of epinephrine in anesthetic finger blocks occurred due to misinterpretation of reports of necrosis occurring, which were not actually caused by epinephrine. That myth influenced the appearance of a dogma. The history of the use of epinephrine in anesthetic finger blocks demonstrates that superficial and misleading interpretations of clinical complications published as case reports can breed myth and dogma. Only science can prevent and destroy such medical myths and dogmas(AU)

Dysregulation in the secretion of the stress-related catecholamines in oral cancer patients: predictors and prognostic value / Desregulação da secreção das catecolaminas relacionadas ao estresse em pacientes com câncer de boca: valor preditivo e prognóstico

Introdução: Pacientes com câncer podem apresentar uma hiperativação do Sistema Nervoso Simpático (SNS). Como consequência, uma desregulação na secreção das catecolaminas relacionadas ao estresse norepinefrina (NE) e epinefrina (EPI) têm sido implicadas na progressão de alguns tipos de tumores malignos. No entanto, a associação entre os níveis sistêmicos das catecolaminas e o prognóstico do câncer, bem como seus fatores preditores são pobremente conhecidos. Pacientes e métodos: O presente estudo investigou os níveis plasmáticos de NE e EPI em 168 pacientes com carcinoma espinocelular (CEC) de boca, 70 pacientes com leucoplasia bucal e 54 voluntários saudáveis; bem como sua associação com variáveis demográficas, clínicopatológicas, biocomportamentais e psicológicas nos pacientes oncológicos. Os níveis plasmáticos de NE e EPI foram medidos por cromatografia líquida de alta eficiência com detecção eletroquímica (CLAE-ED) e o estado psicológico de humor foi avaliado pela Escala de Humor de Brunel (BRUMS). Análise de Kaplan-Meier e regressão de Cox foram usadas para investigar as associações entre os níveis de NE e EPI e a sobrevida global e específica após 5 anos de follow-up em 82 pacientes com câncer de boca. Os níveis sistêmicos das catecolaminas também foram avaliados em 32 pacientes após o tratamento da doença e comparados com os níveis pré-tratamento. Resultados: As concentrações plasmáticas de NE e EPI foram significativamente maiores em pacientes com CEC de boca em comparação aos pacientes com leucoplasia bucal (p< 0,0001 e p=0,024, respectivamente). Os pacientes com CEC de boca também apresentaram níveis plasmáticos de NE mais elevados do que os voluntários saudáveis (p= 0,0002). As concentrações plasmáticas de NE nos pacientes com leucoplasia bucal foram menores do que os voluntários saudáveis (p= 0,032). Análises de regressão múltipla mostraram que níveis aumentados de NE foram significativamente associados com uma sensação de "sentir-se sem energia", um descritor medido pelo BRUMS (OR= 2,9; p= 0,023). Baixa escolaridade e ocorrência de comorbidades com maior severidade foram independentemente associados a altos níveis de EPI (OR= 4,0; p= 0,004 e OR= 7,2; p= 0,005; respectivamente). Além disso, a presença de um estado de humor de raiva e "não estar em alerta" foram associados a altos níveis plasmáticos de EPI (OR= 2,6; p= 0,039 e OR= 3,2; p= 0,010, respectivamente). Os resultados mostraram que os pacientes com CEC de boca não casados e que tinham pior renda familiar foram preditivos para menor sobrevida global dos pacientes com CEC de boca (p< 0,05). Estágio clínico avançado foi associado à diminuição da sobrevida global (HR= 5,2; p= 0,000) e específica do câncer (HR= 4,2; p= 0,000). A análise de regressão de Cox também evidenciou que níveis sistêmicos aumentados tanto de NE como de EPI foram associados à menor sobrevida global (HR= 3,4; p= 0,002 e HR= 2,8; p=0,006, respectivamente). Os pacientes com CEC de boca apresentaram níveis plasmático de NE mais baixos após o tratamento do câncer em comparação com a fase pré-tratamento (p= 0,0008). Conclusão: Os resultados do presente estudo mostram que pacientes com câncer de boca podem apresentar níveis sistêmicos elevados das catecolaminas norepinefrina e epinefrina, e que esta desregulação hormonal associada com fatores clinicopatológicos e psicológicos é preditiva para pior sobrevida global(AU)

Introduction: Cancer patients may have a hyperactivation of the Sympathetic Nervous System (SNS). Therefore, dysregulation in the secretion of the stress-related catecholamines norepinephrine (NE) and epinephrine (EPI) have been implicated in the progression of some types of cancer. However, the association between systemic levels of catecholamines and cancer prognosis, as well as its predictors, are poorly understood. Patients and methods: The present study investigated the plasma NE and EPI levels in 168 patients with oral squamous cell carcinoma (OSCC), 70 patients with oral leukoplakia and 54 healthy volunteers; as well as its association with demographic, clinicopathological, biobehavioral and psychological variables in cancer patients. Plasma NE and EPI levels were measured by high performance liquid chromatography with electrochemical detection (HPLC-ED) and psychological mood states was assessed by the Brunel Mood Scale (BRUMS). Kaplan-Meier analysis and Cox regression were used to investigate associations between the systemic levels of catecholamines and overall and specific survival after 5 years of follow-up in 82 patients with oral cancer. Systemic levels of catecholamines were also evaluated in 32 patients after oral cancer treatment and were compared with pre-treatment levels. Results: Plasma NE and EPI concentrations were significantly higher in patients with oral SCC compared to patients with oral leukoplakia (p<. 0001 and p=.024, respectively). Patients with oral SCC also displayed higher plasma NE levels than healthy volunteers (p=.0002). Patients with oral leukoplakia had lower plasma NE levels than healthy volunteers (p=.032). Multiple regression analyzes showed that increased NE levels were associated with a feeling of "no energy", a descriptor measured by BRUMS (OR= 2.9; p= .023). Low education and the occurrence of severe comorbidities were independently associated with high levels of EPI (OR= 4.0; p= .004 and OR= 7.2; p= .005; respectively). Furthermore, the presence of an angry mood state and denial of "being on alert" were associated with high EPI levels (OR= 2.6; p= .039 and OR= 3.2; p= .010, respectively). The results showed that nonmarried oral SCC patients and those who had a lower family income had lower overall survival in patients with oral SCC (p< 0.05). Advanced clinical stage was associated with decreased overall (HR=5.2; p=.000) and cancer-specific (HR=4.2; p=.000) survival. Cox regression analysis also showed that increased levels of both NE and EPI were associated with worse overall survival (HR=3.4; p=.002 and HR=2.8; p=.006, respectively). Patients with oral SCC had lower plasma NE levels after cancer treatment compared to the pre-treatment period (p=.0008). Conclusion: The results of the present study reveal that patients with oral cancer may have high systemic levels of the catecholamines norepinephrine and epinephrine, and that this hormonal dysregulation is associated with clinicopathological and psychological factors and predictive for worse overall survival(AU)

Efficacy of epinephrine in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis: a meta-analysis / 中华消化内镜杂志

Objective:To systematically evaluate the efficacy of epinephrine in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP).Methods:Randomized controlled trials (RCTs) on epinephrine for preventing PEP from inception to October 10, 2020 were searched in databases including PubMed, Embase, The Cochrane Library, Web of Science, VIP Information Network, China National Knowledge Infrastructure,WanFang Data,and clinical trial registration platforms including ClinicalTrials.gov,WHO International Clinical Trial Registration Platform. Literature was screened independently by two reviewers, data were extracted and the risk of bias of included studies were assessed. The meta-analysis was performed by RevMan 5.3.Results:A total of 410 papers were retrieved and 8 RCTs involving 4 208 patients were included. The results of meta-analysis showed that compared with the saline group, the epinephrine could reduce the incidence of PEP ( RR=0.29,95% CI:0.16-0.50, P<0.001). There were no significant differences in the therapeutic effect between group epinephrine and group indomethacin ( RR=0.17,95% CI:0.02-1.39, P=0.100) or group indomethacin combined with epinephrine and group indomethacin ( RR=1.15,95% CI:0.61-2.16, P=0.670). Conclusion:Local spraying of epinephrine on the duodenal papilla can reduce the incidence of PEP compared with normal saline. But the epinephrine or combination of indomethacin and epinephrine fails to reveal any benefit over indomethacin alone in preventing PEP.

Concerns children with anaphylaxis in China: Implementing China Children′s Anaphylaxis Emergency Action Plan / 中华实用儿科临床杂志

The prevalence of anaphylaxis, which is underdiagnosed and undertreated, has been increasing recently.It was reported that about one fourth of anaphylaxis patients were children and there were some critical gaps in the initial treatment of anaphylaxis, including epinephrine use, when compared to the guidelines.Since most of anaphylaxis cases happen outside of medical institutions, and could recur unexpectedly, it is important for children with anaphylaxis to get long-term management.In order to improve management of anaphylaxis, a written China Children′s Anaphylaxis Emergency Action Plan (CCAEAP) is developed.It is a tool for children and parents/caregiver to recognize the symptoms and signs of anaphylaxis as early as possible and take proper action immediately, including using a predefined dose of intramuscular epinephrine and accessing to emergency department.

HPLC assay of epinephrine sulfonate in epinephrine injection / 药学学报

An HPLC method was established for the assay of epinephrine sulfonate (impurity F) in epinephrine injection. The determination was performed on an AQUASIL C18 (100 mm × 4.6 mm, 3 μm) column with a gradient elution system, and the mobile phase was consisted of monopotassium phosphate solution (mobile phase A) and acetonitrile (mobile phase B). The injection volume was 40 μL. The detection wavelength was at 210 nm and the column temperature was 25 ℃. The total analytical time was 40 min. The results showed that the standard cure of epinephrine sulfonate (impurity F) between peak area and concentration exhibited good linear relationship within the ranges of 0.520-12.480 μg·mL-1 and the R2 = 0.999 8. The average recovery rate was 103.04% and the RSD was 2.00%. The limit concentration of detection was 0.104 μg·mL-1 and the limit concentration of quantitation was 0.520 μg·mL-1. The method could be applied to the determination of epinephrine sulfonate in epinephrine injection with high accuracy and precision, as well as good sensitivity. It could also enhance the quality standards of epinephrine-related products.

Catecholamines production by kidney tissue and mesangial cell culture is differentially modulated by diabetes / A produção de catecolaminas pelo tecido renal e a cultura de células mesangiais é modulada diferencialmente pelo diabetes

Abstract Introduction: According to the International Diabetes Federation, the number of people with diabetes mellitus may reach 700 million in 2045. Catecholamines are involved in the regulation of several kidney functions. This study investigates the effects of hyperglycemia on catecholamines' metabolism in kidney tissue from control, diabetic, and insulin-treated diabetic rats, both in vivo and in vitro. Methods: Male Wistar-Hannover rats were randomized into: control, diabetic, and insulin-treated diabetic groups. Diabetes was induced by a single injection of streptozotocin, and diabetic treated group also received insulin. After 60 days, blood and kidney tissue from all groups were collected for catecholamines' quantification and mesangial cells culture. Results: diabetic rats had lower body weight, hyperglycemia, and increase water intake and diuresis. Additionally, diabetes promoted a sharp decrease in creatinine clearance compared to control group. Regarding the whole kidney extracts, both diabetic groups (treated and non-treated) had significant reduction in norepinephrine concentration. In mesangial cell culture, catecholamines' concentration were lower in the culture medium than in the intracellular compartment for all groups. Norepinephrine, epinephrine, and dopamine medium levels were increased in the diabetic group. Conclusion: The major finding of the present study was that 8 weeks of diabetes induction altered the kidney catecholaminergic system in a very specific manner, once the production of catecholamines in the excised kidney tissue from diabetic rats was differentially modulated as compared with the production and secretion by cultured mesangial cells.

Resumo Introdução: Segundo a Federação Internacional de Diabetes, o número de pessoas com diabetes mellitus pode chegar a 700 milhões em 2045. As catecolaminas estão envolvidas na regulação de várias funções renais. Este estudo investiga os efeitos da hiperglicemia no metabolismo das catecolaminas no tecido renal de ratos controle, diabéticos e diabéticos tratados com insulina, tanto in vivo como in vitro. Métodos: Os ratos Wistar-Hannover machos foram randomizados em: grupos controle, diabéticos e diabéticos tratados com insulina. O diabetes foi induzido por uma única injeção de estreptozotocina, e o grupo diabético tratado também recebeu insulina. Após 60 dias, sangue e tecido renal dos grupos foram coletados para quantificação de catecolaminas e cultura de células mesangiais. Resultados: ratos diabéticos apresentaram peso corporal mais baixo, hiperglicemia, e aumento da ingestão de água e diurese. Ademais, o diabetes promoveu uma redução acentuada na depuração de creatinina comparado com o grupo controle. Quanto aos extratos de rim total, ambos os grupos diabéticos (tratados/não tratados) tiveram redução significativa na concentração de noradrenalina. Na cultura de células mesangiais, a concentração de catecolaminas foi menor no meio de cultura do que no compartimento intracelular para todos os grupos. Níveis médios de noradrenalina, adrenalina e dopamina estavam aumentados no grupo diabético. Conclusão: O principal achado deste estudo foi que 8 semanas de indução de diabetes alteraram o sistema catecolaminérgico renal de maneira muito específica, já que a produção de catecolaminas no tecido renal excisado de ratos diabéticos foi modulada diferencialmente comparada com produção e secreção por células mesangiais cultivadas.

Anafilaxia no primeiro ano de vida: como diagnosticar / Anaphylaxis in the first year of life: how to diagnose

A anafilaxia é uma reação alérgica mais grave e potencialmente fatal. Apresenta-se quase sempre com manifestações cutâneas, acompanhadas por acometimento dos sistemas respiratório, gastrointestinal, nervoso e cardiovascular. Indivíduos de todas as faixas etárias podem manifestar anafilaxia, e seu diagnóstico no primeiro ano de vida é difícil por ser o lactente incapaz de expressar de modo claro as sensações vividas durante o episódio agudo. Nessa faixa etária os alimentos são os agentes desencadeantes mais envolvidos, embora medicamentos e veneno de himenópteros também o sejam. Em pacientes submetidos a várias cirurgias e procedimentos médicos a alergia ao látex pode ocorrer. A adrenalina intramuscular é a primeira linha de tratamento da anafilaxia na fase inicial, mas continua sendo subutilizada. Além disso, medidas de suporte, tais como decúbito supino, reposição de fluidos, vias aéreas pérvias e oxigenação, devem ser instituídas. Após a alta, o paciente deve ser encaminhado à avaliação e seguimento por especialista visando à identificação do agente desencadeante, assim como educar responsáveis/cuidadores destes pacientes sobre a prevenção de novos episódios. É importante que esse paciente tenha consigo algum tipo de identificação que o aponte como tendo tido episódio de anafilaxia, sobretudo se tiver sido recorrente. A oferta de um plano escrito de como proceder diante de um novo episódio é fundamental.

Anaphylaxis is a serious and potentially fatal allergic reaction. Most frequently, it features cutaneous manifestations accompanied by involvement of the respiratory, gastrointestinal, nervous, and/or cardiovascular systems. Individuals of all age groups may present with anaphylaxis, and its diagnosis in the first year of life is difficult because the infant is unable to clearly express the sensations experienced during the acute episode. In this age group, foods are the most common triggering agents, together with medications and Hymenoptera venom. In patients undergoing multiple surgeries and medical procedures, latex allergy may occur. Intramuscular epinephrine is the first line of treatment for early anaphylaxis, but it remains underutilized. In addition, supportive measures such as supine decubitus, fluid replacement, patent airways, and oxygenation should be instituted. After discharge, the patient should be referred for evaluation and follow-up by a specialist, with the purpose of identifying the triggering agent as well as educating the caregivers of these patients about the prevention of new episodes. This patient should always carry some type of identification that indicates that he/she has had any episode of anaphylaxis, especially if it has been recurrent. Providing a written plan of how to proceed in the face of a new episode is essential.

Cirugía de mano con anestesia local con técnica WALANT. Experiencia con una serie de casos / Hand surgery with local anesthesia with WALANT technique. Experience with a cases series

Resumen Introducción: Los procedimientos en cirugía de mano requieren el uso de torniquete para evitar el sangrado y, generalmente, utilizan sedación por anestesiología para controlar el dolor e incomodidad del torniquete. Hace una década se viene usando en cirugía de mano anestesia local sin torniquete ni sedación, como una opción segura y eficiente para las intervenciones quirúrgicas; esta técnica es conocida como WALANT (en inglés). El objetivo del trabajo es evaluar una serie prospectiva de pacientes intervenidos con técnica de WALANT en cirugía de mano. Métodos: Es una serie de casos que caracteriza el desempeño de una técnica anestésica local para procedimientos en cirugía de mano sin sedación y sin torniquete. Se evaluaron tiempo de cirugía, dolor intra- y posoperatorio y nivel de satisfacción. Este trabajo es aceptado por el comité de ética. Resultados: Se operaron 96 pacientes, 73 fueron cirugías de partes blandas y 23 de partes óseas. 92 pacientes (96 %) refirieron estar satisfechos y sin dolor posoperatorio. En 4 casos fue necesaria sedación intraoperatoria. Ningún paciente requirió torniquete. No fue necesario usar volúmenes mayores a 40 ml, sin embargo, estos varían según el tipo de intervención. Conclusiones: Este estudio muestra que la técnica funciona muy bien, y es de gran utilidad en cirugías de tendones, donde se requiere que el paciente esté despierto para evaluar el funcionamiento intraoperatorio. Los costos de cirugía son más baratos y es una técnica reproducible, con un desempeño satisfactorio.

Abstract Introduction: Procedures in hand surgery require tourniquet use to control bleeding and generally sedation by anesthesiology to manage the pain and discomfort of the tourniquet. A decade ago, local anesthesia without tourniquet or sedation was used in hand surgery as a safe and efficient option for surgical interventions, known as WALANT (Wide Awake Local Anesthesia with No Tournique) technique. The aim of the study is to evaluate a prospective series of patients who have undergone surgery with the WALANT technique in hand surgery. Methods: Consecutive series of cases that show the performance of a local anesthetic technique for procedures in hand surgery without sedation and without tourniquet. Surgery time, intra and postoperative pain and satisfaction level were evaluated. This study was accepted by the ethics committee. Results: Ninety-six patients underwent surgery, seventy-three were soft tissue surgery and twenty-three bone surgery. Ninety-two patients (96%) reported being satisfied and without postoperative pain. In four cases, intraoperative sedation was necessary. No patient required a tourniquet. It was not necessary to use volumes greater than 40 ml; however, these vary according to the type of intervention. Conclusions: This study shows that the technique works very well and is very useful in tendon surgeries, where the patient is required to be awake to evaluate intraoperative functioning. Surgery costs are cheaper, and it is a reproducible technique with satisfactory performance.

Application of epinephrine saline rinsing solution in hemostasis of cleft palate repair / 中华医学美学美容杂志

Objective:To investigate the hemostatic effect of epinephrine saline rinse solution in cleft palate repair.Methods:A total of 100 children who underwent cleft palate repair in the operating room of the Second Affiliated Hospital of Shantou University Medical College from 2018 to 2020 were selected, Among them, 51 were males and 49 females, aged from 6 months to 12 years, with an average (2.5±2.49) years. The patients were divided into two groups according to whether to use epinephrine saline flushing fluid: in group A, 43 cases were treated with adrenaline saline irrigation solution to wash the incision during the operation; gauze soaked in rinse solution was used to fill the oral cavity before endotracheal intubation and extubation after operation; in B group of 57 cases, no intraoperative rinses were used. The intraoperative blood loss and operation duration were compared between the two groups.Results:Intraoperative use in group A after adrenaline saline rinses showed that the intraoperative blood loss of children (16.23±4.88) ml was significantly lower than that of group B (19.26±4.13) ml. The duration of operation in group A (109.79±40.27) min was significantly shorter than that in group B (137.16±50.47) min, The difference was statistically significant ( t=2.92, P<0.05). Conclusions:The incision is rinsed with epinephrine saline solution during cleft palate repair. In addition, before endotracheal intubation and extubation after operation, gauze soaked in rinsing solution is used to fill the oral cavity, which could significantly reduce the amount of bleeding and shorten the operation time.

Terapia endoscópica combinada en hemorragia diverticular de colon / Combined endoscopic therapy for colonic diverticular bleeding

La hemorragia diverticular es la causa más frecuente de hemorragia digestiva baja. La hemorragia es abrupta, indolora, abundante. La mayoría de los divertículos que sangran se localizan en el lado derecho, este sangrado se autolimita hasta en un 80% de los casos. Cuando no se autolimita su manejo puede llegar a ser complejo. El manejo de estos sangrados, pueden variar desde conservador, endoscópico, arteriografía más embolización y el quirúrgico. Entre las alternativas de manejo endoscópico, tenemos la terapia de inyección, la térmica, hemoclips, ligadura con banda. El presente caso es de un paciente con hemorragia diverticular en el que se realizó terapia endoscopica combinada, infiltración de adrenalina, aplicación indirecta de hemoclips y aplicación tópica de ácido tranexámico que es un antifibrinolítico.

Diverticular bleeding is the most common cause of lower GI bleeding. The bleeding is most often abrupt, painless and abundant. Most of the bleeding diverticula are located on the right side of the colon, this bleeding is self-limited in up to 80% of cases. When it is not, it could turn into a difficult situation to manage. The management of these bleeds can vary from conservative to an endoscopic, arteriography plus embolization and surgical. Among the endoscopic management alternatives, we have injection therapy, thermal therapy, hemoclips, band ligation. The present case is about a patient with diverticular bleeding who underwent combined endoscopic therapy, adrenaline infiltration, indirect application of hemoclips, and topical application of tranexamic acid, which is an antifibrinolytic.

RESUMEN Objetivo: Analizar la evolución clínica de niños con shock séptico refractario a volumen tratados inicialmente con dopamina o adrenalina. Métodos: Estudio de cohorte retrospectivo con ámbito en un servicio de urgencias pediátrico de un hospital de tercer nivel. Población: niños ingresados con shock séptico refractario a volumen. Se comparó la evolución clínica entre 2 grupos: Grupo Dopamina y Grupo Adrenalina. Las variables de interés fueron: uso de ventilación mecánica invasiva, días de inotrópicos, estancia hospitalaria, estancia en cuidados intensivos y mortalidad. Para variables numéricas y categóricas utilizamos medidas de tendencia central y para comparación las pruebas de U Mann Whitney y χ2 test. Resultados: Incluimos 118 pacientes. El 58,5% recibió dopamina y 41,5% adrenalina. El uso de ventilación mecánica invasiva fue 38,8% para adrenalina versus 40,6% para dopamina (p = 0,84) con una mediana de 4 días para adrenalina y 5,5 para dopamina (p = 0,104). La mediana para días de inotrópicos fue de 2 días para ambos grupos (p = 0,714). La mediana de estancia hospitalaria fue de 11 para adrenalina y 13 para dopamina (p = 0,554) y de estancia en cuidados intensivos se registró una mediana de 4 días (0 - 81 días) siendo igual en ambos grupos (p = 0,748). La mortalidad fue de 5% para el Grupo Adrenalina versus 9% para el Grupo Dopamina (p = 0,64). Conclusiones: En nuestro centro, no observamos diferencias en uso de ventilación mecánica invasiva y tiempo de inotrópicos, estancia hospitalaria y cuidados intensivos y mortalidad entre niños ingresados al servicio de urgencias pediátrico con diagnóstico de shock séptico refractario a volumen tratados inicialmente con dopamina o adrenalina.

Abstract Objective: To analyze the clinical outcome of children with fluid-refractory septic shock initially treated with dopamine or epinephrine. Methods: A retrospective cohort study was conducted at a pediatric emergency department of a tertiary hospital. Population: children admitted because of fluid-refractory septic shock. Clinical outcome was compared between two groups: Dopamine and Epinephrine. Variables evaluated were use of invasive mechanical ventilation, days of inotropic therapy, length of hospital stay, intensive care stay, and mortality. For numerical and categorical variables, we used measures of central tendency. They were compared by the Mann-Whitney U-test and the (2 test. Results: We included 118 patients. A total of 58.5% received dopamine and 41.5% received epinephrine. The rate of invasive mechanical ventilation was 38.8% for epinephrine versus 40.6% for dopamine (p = 0.84), with a median of 4 days for the Epinephrine Group and 5.5 for the Dopamine Group (p = 0.104). Median time of inotropic therapy was 2 days for both groups (p = 0.714). Median hospital stay was 11 and 13 days for the Epinephrine and Dopamine groups, respectively (p = 0.554), and median stay in intensive care was 4 days (0 - 81 days) in both groups (p = 0.748). Mortality was 5% for the Epinephrine Group versus 9% for the Dopamine Group (p = 0.64). Conclusions: At our center, no differences in use of invasive mechanical ventilation, time of inotropic therapy, length of hospital stay, length of intensive care unit stay, or mortality were observed in children admitted to the pediatric emergency department with a diagnosis of fluid-refractory septic shock initially treated with dopamine versus epinephrine.
