ABSTRACT

Objective This study aimed to identify risk factors for increased perioperative bleeding in scoliosis surgery. Methods This is a prospective cohort study including 30 patients with idiopathic scoliosis undergoing posterior instrumentation using the pedicle screw system at a university hospital. Results Intraoperative blood losses totaled 798.6 ± 340 mL (24.8% of blood volume). Nine subjects presented massive blood loss. On average, hemoglobin dropped by 3.7 g/dL, and each patient received 1.4 blood bags. Postoperative blood loss was 693.4 ± 331.1 mL, and the total number of days using a drain was 2.7 ± 0.7. Intraoperatively, the following variables showed significant correlations ( p < 0.05) with increased bleeding: age, time from diagnosis to treatment, preoperative Cobb angle, amount of curve correction, number of instrumented and fixated levels, total number of screws, and the number of transfused bags. Postoperatively, the following variables had significant correlations ( p < 0.05): age, preoperative Cobb angle, length of hospital stay, number of blood bags transfused, and number of levels fixated with screws. Conclusion The variables most contributing to blood loss were age, preoperative Cobb angle, number of blood bags transfused, and number of levels fixated with a screw. Therefore, patients may benefit from surgical treatment while younger and presenting a lower Cobb angle, consequently requiring a lower degree of curve correction and lower-density implants.

ABSTRACT

Background: Blood loss estimation in a surgery is made by anesthesiologists by means of visual technique, which is not reliable because it can change depending on the judgement of every person, or his/her work experience, which is why it is considered something subjective. Therefore, the results obtained could lead to make mistakes with the exact amount of bleeding, mismanaging unnecessary hemoderived transfusions or administering unnecessary drugs. Objective: To compare the blood volume and its visual calculation between Anesthesiology residents and anesthesiologists. Material and methods: Prolective cross-sectional study which included 85 Anesthesiology residents and anesthesiologists. Diverse scenarios of bleeding were set, divided into gauze pads, compresses and jars, and each participant was asked to answer the poll. Results: There is no significant difference in the estimate of bleeding between the estimation made by residents and anesthesiologists. Conclusions: The grade of studies or experience is not significant for the exact estimation of bleeding with visual technique.


Introducción: la estimación de sangrado en las cirugías se realiza por medio de la técnica de cálculo visual, que es llevada a cabo por parte del servicio de anestesiología. Se trata de una técnica poco confiable, que puede variar dependiendo del juicio de cada persona y de su experiencia laboral, por lo que es considerada algo subjetivo. Por lo tanto, los datos arrojados hacen que se cometan errores en la cantidad exacta del sangrado y llevan a transfusiones de paquetes globulares o a la administración probablemente innecesaria de medicamentos. Objetivo: comparar la cantidad de un volumen de sangrado determinado y su cálculo visual realizada por residentes de Anestesiología y anestesiólogos. Material y métodos: estudio transversal prolectivo en el cual se incluyeron 85 médicos residentes de Anestesiología y anestesiólogos. Se dispusieron diversos escenarios con sangrado, los cuales se dividieron en gasas, compresas y frascos, y se le pidió a cada médico que contestara la encuesta correspondiente según su criterio. Resultados: de acuerdo con los resultados, no hay diferencia significativa en la estimación realizada del sangrado entre residentes y anestesiólogos para las muestras estudiadas. Conclusiones: el grado de estudios o experiencia no es significativo para la exacta estimación de sangrado con técnica visual.

ABSTRACT

Tranexamic acid (TXA) is one of the measures indicated to reduce bleeding and the need for volume replacement. However, data on risks and benefits are controversial. This study analyzes the effectivity and risks of using tranexamic acid in neurosurgery. We selected articles, published from 1976 to 2019, on the PubMed, EMBASE, Science Direct, and The Cochrane Database using the descriptors: "tranexamic acid," "neurosurgery," "traumatic brain injury," "subdural hemorrhage," "brain aneurysm," and "subarachnoid hemorrhage." TXA can reduce blood loss and the need for blood transfusion in trauma and spinal surgery. Despite the benefits of TXA, moderate-to-high doses are potentially associated with neurological complications (seizures, transient ischemic attack, delirium) in adults and children. In a ruptured intracranial aneurysm, the use of TXA can considerably reduce the risk of rebleeding, but there is weak evidence regarding its influence on mortality reduction. The TXA use in brain surgery does not present benefit. However, this conclusion is limited because there are few studies. TXA in neurosurgeries is a promising method for the maintenance of hemostasis in affected patients, mainly in traumatic brain injury and spinal surgery; nevertheless, there is lack of evidence in brain and vascular surgeries. Many questions remain unanswered, such as how to determine the dosage that triggers the onset of associated complications, or how to adjust the dose for chronic kidney disease patients.

ABSTRACT

Abstract The liver is the most commonly affected solid organ in cases of abdominal trauma. Management of penetrating liver trauma is a challenge for surgeons but with the introduction of the concept of damage control surgery accompanied by significant technological advancements in radiologic imaging and endovascular techniques, the focus on treatment has changed significantly. The use of immediately accessible computed tomography as an integral tool for trauma evaluations for the precise staging of liver trauma has significantly increased the incidence of conservative non-operative management in hemodynamically stable trauma victims with liver injuries. However, complex liver injuries accompanied by hemodynamic instability are still associated with high mortality rates due to ongoing hemorrhage. The aim of this article is to perform an extensive review of the literature and to propose a management algorithm for hemodynamically unstable patients with penetrating liver injury, via an expert consensus. It is important to establish a multidisciplinary approach towards the management of patients with penetrating liver trauma and hemodynamic instability. The appropriate triage of these patients, the early activation of an institutional massive transfusion protocol, and the early control of hemorrhage are essential landmarks in lowering the overall mortality of these severely injured patients. To fear is to fear the unknown, and with the management algorithm proposed in this manuscript, we aim to shed light on the unknown regarding the management of the patient with a severely injured liver.


Resumen El hígado es el órgano solido más comúnmente lesionado en casos de trauma abdominal. El manejo del trauma penetrante hepático es un dilema para los cirujanos. Sin embargo, con la introducción del concepto de la cirugía de control de daños y los avances tecnológicos en imagenología y técnicas endovasculares han permitido que el enfoque del tratamiento cambie. La disponibilidad inmediata de la tomografía computarizada permite estadificar el grado de la lesión e incrementar la posibilidad de un manejo conservador en pacientes hemodinámicamente estables con trauma hepático. El trauma hepático severo que se asocia con inestabilidad hemodinámica tiene una alta mortalidad debido a la hemorragia activa. El objetivo de este artículo es proponer un algoritmo de manejo producto de un consenso de expertos acerca del abordaje de los pacientes hemodinámicamente inestables con trauma hepático penetrante. El manejo debe ser por parte de un equipo multidisciplinario que comienza desde la evaluación inicial de los pacientes, la activación temprana de protocolo de transfusión masiva y el control temprano de la hemorragia, siendo estos aspectos esenciales para disminuir la mortalidad. El miedo a lo desconocido es el dilema quirúrgico donde existen pocas opciones y es imperante decisiones rápidas y oportunas; por esta razón, se propone dar una luz de guía sobre lo desconocido respecto al manejo del paciente con trauma hepático severo.

ABSTRACT

Abstract Objective The aim of the present study is to identify the incidence, predisposing factors and prognostic impact of blood loss in patients with neuromuscular scoliosis submitted to corrective surgery. Methods Retrospective cohort study, including pediatric patients diagnosed with neuromuscular scoliosis undergoing instrumentation and posterior vertebral fusion in a university hospital. Patient characteristics were collected from the hospital information system. Results A total of 39 patients were included in the study. The intraoperative blood losses were 962 ml, representing a loss of 35.63% of the blood volume. In 20 cases, there was a massive blood loss (> 30%) and only 7 patients did not need a transfusion. The group of patients with massive blood loss had a slightly higher age (13.75 versus 13.53 years old), a lower body mass index (BMI) percentile (25 versus 50), and for each decrease of 0.38 in the BMI, intraoperative blood losses increased 1% (p < 0.05). The value of preoperative albumin had influence on the percentage of blood loss, and for each decrease of 0.4 of albumin, blood loss increased 1% (p < 0.05). Conclusions The factors that most contributed to the differences in blood loss were age, BMI, and preoperative albumin value. There was no significant association between Cobb angle, number of fusion levels and duration of surgery. We can conclude that these patients would benefit from preoperative nutritional control.


Resumo Objetivo O objetivo do presente estudo é identificar a incidência, os fatores predisponentes e o impacto prognóstico da perda de sangue em pacientes com escoliose neuromuscular submetidos a cirurgia corretiva. Métodos Estudo de coorte retrospectiva, incluindo pacientes pediátricos com diagnóstico de escoliose neuromuscular submetidos a instrumentação e fusão vertebral posterior em um hospital universitário. As características dos pacientes foram coletadas no sistema de informações do hospital. Resultados Um total de 39 pacientes foram incluídos no estudo. As perdas sanguíneas intraoperatórias foram de 962 mL, representando uma perda de 35,63% do volume sanguíneo; a perda de sangue foi extensa em 20 casos (> 30%) e apenas 7 pacientes não necessitaram de transfusão. O grupo de pacientes com perda maciça de sangue apresentou idade um pouco maior (13,75 versus 13,53 anos) e menor percentil do índice de massa corporal (IMC) (25 versus 50); para cada diminuição de 0,38 no IMC, as perdas sanguíneas intraoperatórias aumentaram 1% (p < 0,05). A concentração pré-operatória de albumina influenciou o percentual de perda de sangue e, para cada diminuição de 0,4 de albumina, a perda de sangue aumentou 1% (p < 0,05). Conclusões Os fatores que mais contribuíram para as diferenças na perda sanguínea foram idade, IMC e concentração pré-operatória de albumina. Não houve associação significativa entre ângulo de Cobb, número de níveis de fusão e duração da cirurgia. Podemos concluir que esses pacientes se beneficiariam do controle nutricional pré-operatório.

ABSTRACT

ABSTRACT Objective: to estimate the incidence of red blood cell concentrate orders in elective femur fracture repair surgeries and to identify predictors for hemotranfusion. Method: retrospective cohort study conducted with 271 patients submitted to femur fracture repair surgery between July 2013 and July 2016. Surgical and transfusion data were obtained from patient charts and the Transfusion Management System. Association between sociodemographic and clinical variables related to the surgical procedure and the occurrence of red blood cell concentrate transfusion was analyzed using descriptive statistics, the chi-squared test, relative risk, and odds ratio. Multivariate analysis was performed using binomial logistic regression. Results: the incidence of blood orders for patients undergoing femur fracture repair surgery was 87%. Ninety-one (33.6%) patients received red blood cell concentrate transfusions. Even though placing blood orders is recommended, given the possibility of intra- or postoperative transfusions, only 52 (47.2%) blood transfusions occurred in the preoperative period. The variables female sex, low preoperative hemoglobin levels and procedure lasting longer than 120 minutes presented statistical significance (p<0.05) and were considered predictors for hemototransfusion. Conclusion: Perioperative nursing must be aware of the importance of blood orders for all patients undergoing femur fracture repair surgery, including in the preoperative period, with special attention to patients who are female, previously anemic and submitted to long-lasting procedures.


RESUMEN Objetivo: estimar la incidencia de solicitud de reserva de concentrado de hematíes en cirugías electivas de corrección de fractura de fémur, e identificar los predictores para práctica de hemotransfusión. Método: Estudio de cohorte retrospectivo realizado con 271 pacientes sometidos a cirugía de corrección de fractura de fémur, entre julio de 2013 y julio de 2016. Datos quirúrgicos y de transfusiones obtenidos del análisis de historias clínicas y del Sistema de Gestión Transfusional. Se utilizó estadística descriptiva, test de chi-cuadrado, riesgo relativo y razón de oportunidades para analizar la asociación de variables sociodemográficas y clínicas referentes al procedimiento quirúrgico con transfusión de concentrado de hematíes. Para el análisis multivariado se utilizó regresión logística binomial. Resultados: la incidencia de solicitud de reserva para pacientes sometidos a cirugía de corrección de fractura de fémur resultó ser del 87,0%. y 91 (33,6) pacientes foram transfundidos con concentrado de hematíes. A pesar de la recomendación para solicitar reserva, considerando la posibilidad de transfusión intra o postoperatoria, 52 (47,2%) transfusiones se efectuaron en período preoperatorio. Existió significatividad estadística (p<0,05) para las variables: 5sexo femenino, bajos niveles de hemoglobina preoperatoria y duración del procedimiento superior a 120 minutos, considerados como predictores de la hemotransfusión. Conclusión: Resulta esencial que la enfermería perioperatoria tenga conocimiento de la importancia de la reserva sanguínea para todos los pacientes sometidos al tratamiento quirúrgico de la fractura de fémur, incluso en el preoperatorio, estando pendientes de los pacientes femeninos, con anemia previa y sometidos a procedimientos de larga duración.


RESUMO Objetivo: estimar a incidência da solicitação de reserva de concentrado de hemácias em cirurgias eletivas de correção de fratura de fêmur, e identificar os preditores para a ocorrência da hemotransfusão. Método: estudo de coorte retrospectivo realizado com 271 pacientes submetidos à cirurgia de correção de fratura de fêmur, no período de julho de 2013 a julho de 2016. Os dados cirúrgicos e transfusionais foram obtidos a partir da análise dos prontuários e do Sistema de Gestão Transfusional. Utilizou-se a estatística descritiva e, teste qui-quadrado, risco relativo, razão de chances para analisar a associação de variáveis sociodemográficas e clínicas, referentes ao procedimento cirúrgico, com a hemotransfusão de concentrado de hemácias. Para a análise multivariada utilizou-se a regressão logística binomial. Resultados: a incidência de solicitação de reserva para os pacientes submetidos à cirurgia de correção de fratura de fêmur foi de 87,0% e 91 (33,6%) pacientes foram transfundidos com concentrado de hemácias. Apesar da recomendação de solicitar reserva, tendo em vista a possibilidade de transfusão no intra ou pós-operatório, 52 (47,2%) transfusões ocorreram no período pré-operatório. Houve significância estatística (p<0,05) para as variáveis sexo feminino, nível baixo de hemoglobina pré-operatória e duração do procedimento superior a 120 minutos, considerados como preditores para a hemotransfusão. Conclusão: é fundamental que a enfermagem perioperatória tenha o conhecimento da importância da reserva sanguínea para todos os pacientes submetidos ao tratamento cirúrgico da fratura de fêmur, inclusive no pré-operatório, atentando para os pacientes do sexo feminino, previamente anêmicos e submetidos aos procedimentos de longa duração.

ABSTRACT

OBJECTIVE: This study aimed to investigate drain use in a controlled population of patients with hip osteoarthritis undergoing primary total hip arthroplasty. METHODS: This prospective controlled trial evaluated 93 patients randomized into two groups: a group that received drains and a group that did not. The patients who were randomized to the drain group used a 3.2 mm drain placed under the fascia that was kept in place for 24 h. Postoperative evaluations were performed after 24 h and then three, six, and 12 weeks after total hip arthroplasty. The primary outcome was perioperative blood loss in both groups 24 h after total hip arthroplasty. The other parameters that were evaluated included mid-thigh circumference, the rate of blood transfusion, hematocrit, inflammatory serum levels, and the Harris Hip Score. RESULTS: The clinical and laboratory data revealed no differences between the study groups with respect to blood loss and need for blood transfusion, duration of hospital stay, reoperation rate, complications, inflammatory serum markers, and the Harris Hip Score. Patients without closed suction drainage reported higher pain levels after 24 h (VAS score 1 vs. 2, p < 0.01). CONCLUSION: Similar clinical and laboratory outcomes were found in both cohorts.


OBJETIVO: Investigar o uso de drenos em uma população controlada de pacientes com osteoartrose do quadril submetidos a artroplastia total de quadril primária. MÉTODOS: Este estudo prospectivo controlado avaliou 93 pacientes randomizados em dois grupos: um grupo no qual se usou drenos e um grupo no qual não se usou drenos. Os pacientes que foram randomizados para o grupo com drenos utilizaram dreno de 3,2 mm, colocado sob a fáscia, e mantido no local por 24 horas. As avaliações pós-operatórias foram realizadas após 24 horas e três, seis e 12 semanas após a artroplastia total de quadril. O desfecho primário foi perda sanguínea perioperatória em ambos os grupos 24 horas após a artroplastia total de quadril. Os demais parâmetros avaliados foram circunferência do meio da coxa, taxa de transfusão de sangue, hematócrito, níveis séricos inflamatórios e Harris Hip Score. RESULTADOS: Os dados clínicos e laboratoriais não indicaram diferenças entre os grupos de estudo quanto à perda de sangue e necessidade de transfusão de sangue, tempo de internação hospitalar, taxa de reoperação, complicações, marcadores séricos inflamatórios e Harris Hip Score. Os pacientes que não usaram drenos de sucção fechada relataram maiores níveis de dor após 24 horas (EVA 1 vs. 2, p < 0,01). CONCLUSÃO: Encontramos resultados clínicos e laboratoriais semelhantes em ambas as coortes.

ABSTRACT

OBJECTIVES: To evaluate bleeding and the estimated blood loss in patients who underwent total knee replacement (TKR) with different closed suction drains (3.2-mm and 4.8-mm gauge). METHODS: This was a randomized controlled trial with 22 patients who underwent TKR and were divided into two groups: Group I, with 11 patients in whom the 3.2-mm suction drain was used, and Group II, with 11 patients in whom the 4.8-mm suction drain was used. The hematocrit was measured after 24, 48 and 72 h after surgery in order to calculate the estimated blood loss. The drained volume was measured 3, 6, 12, 24, and 48 h after TKR, and thereafter both groups were compared. RESULTS: Regarding the hematocrit, there were no differences between groups in measured periods (24, 48, and 72 h after surgery). The total bleeding measured at the suction drains within 48 h was higher in Group II, with a statistically significant difference (p = 0.005); in the first 24 h, there was major bleeding in Group II (mean 893 mL), with a significant difference (p = 0.004). Between 24 and 48 h, there was no statistically significant difference in both groups (p = 0.710). The total estimated bleeding was higher in Group I, with mean of 463 mL, versus 409 mL in Group II, with no statistical significance (p = 0.394). CONCLUSIONS: Bleeding was higher in the group that used the 4.8 mm gauge suction drain, with no differences in hematocrit and estimated blood loss.

ABSTRACT

PURPOSE: To determine the predictive factors for postoperative urinary incontinence (UI) following holmium laser enucleation of the prostate (HoLEP) during the initial learning period. PATIENTS AND METHODS: We evaluated 127 patients with benign prostatic hyperplasia who underwent HoLEP between January 2011 and December 2013. We recorded clinical variables, including blood loss, serum prostate-specific antigen levels, and the presence or absence of UI. Blood loss was estimated as a decline in postoperative hemoglobina levels. The predictive factors for postoperative UI were determined using a multivariable logistic regression analysis. RESULTS: Postoperative UI occurred in 31 patients (24.4%), but it cured in 29 patients (93.5%) after a mean duration of 12 weeks. Enucleation time >100 min (p=0.043) and blood loss >2.5g/dL (p=0.032) were identified as significant and independent risk factors for postoperative UI. CONCLUSIONS: Longer enucleation time and increased blood loss were independent predictors of postoperative UI in patients who underwent HoLEP during the initial learning period. Surgeons in training should take care to perform speedy enucleation maneuver with hemostasis.

ABSTRACT

Antecedentes: La gonartrosis es una patología degenerativa que limita de forma importante la funcionalidad de una persona. Se recurre al manejo quirúrgico cuando el paciente presenta una limitación funcional importante así como dolor intenso. La artroplastía de rodilla es una de las cirugías con mejores resultados funcionales en pacientes con esta patología, pero dentro de sus limitaciones está la posibilidad de un sangrado importante y, por consiguiente, la necesidad de hemotransfundir al paciente. El objetivo de este estudio fue evaluar la necesidad de hemotransfundir a los pacientes operados de artroplastía de rodilla que utilizaron recuperador sanguíneo en el postoperatorio y las diferencias entre los costos del recuperador sanguíneo y la transfusión clásica. Métodos: Estudio retrospectivo, transversal y retrolectivo de 300 expedientes de pacientes operados en el Hospital Ángeles de Querétaro de artroplastía de rodilla que utilizaron recuperador sanguíneo que requirieron hemotransfusión alogénica entre Octubre 2001 y Junio 2013. Resultados: De las 246 rodillas operadas, solamente tres requirieron hemotransfusión alogénica. Ninguna complicación/infección con el uso de recuperador sanguíneo. La edad promedio de los pacientes fue de 67.1 ± 9.78 años con un predominio femenino siendo éstos 141 (60.5%) en comparación con 92 (39.5%) masculinos. La sangre recolectada vía recuperador sanguíneo varió de 150 a 1,225 ml con un promedio de 318 ± 100.6 ml, la cual fue retransfundida a cada paciente. Conclusiones: El uso de recapturador sanguíneo en pacientes postoperados de artroplastía de rodilla disminuye de forma importante la necesidad de hemotransfusión alogénica.


Backgound: Gonarthrosis is a degenerative condition that importantly limits an individual's performance. Surgical treatment is used in patients with important functional limitation and severe pain. Knee arthroplasty is one of the surgeries with the best functional results in patients with this condition. However, its limitations include the risk of heavy bleeding and the resulting need for blood transfusion. The objective of this study was to assess the need for blood transfusion in patients undergoing knee arthroplasy in whom the cell saver was used postoperatively and find out the cost differences between the cell saver and standard blood transfusion. Methods: Retrospective, cross-sectional, retrolective trial including 300 records of patients who underwent knee arthroplasty at Hospital Ángeles Querétaro that included the use of the cell saver and allogeneic blood transfusion from October 2001 to June 2013. Results: Only 3 of the 246 operated knees required allogeneic blood transfusion. There were no complications/infections resulting from the use of the cell saver. Mean age of patients was 67.1 ± 9.78 years; females were predominant, as they were 141 (60.5%), compared to 92 (39.5%) males. The blood collected with the cell saver ranged from 150 to 1,225 ml with a mean of 318 ± 100.6 ml and was retransfused to each patient. Conclusions: Cell saver use in patients subjected to knee arthroplasty importantly decreases the need for allogeneic blood transfusion.

ABSTRACT

OBJECTIVE: Compare blood loss in 40 patients underwent to unilateral total knee replacement with the release of ischemia before and after skin closure and compressive dressing. METHODS: in a prospective randomized study, in 40 patients underwent to total knee replacement, dividing then into two groups: group A in which the ischemia was released before skin closure, allowing bleeding control and group B where the ischemia was released after skin suture and pressure dressing. We compared the results of laboratory tests of serum hemoglobin before surgery and 48 hours postoperatively, the blood volume contained in vacuum suction drain and the transfusions that was necessary. RESULTS: As a result, the post operative serum hemoglobin levels had a mean decrease of 3.57 g/dL in group A and 4.24 g/dL in group B with an average of 0.67g/dL difference between them, statistically insignificant.The observed mean drainage, in the vacuum drain, were 705 mL in group A and 700 mL in group B. The 5ml difference between medians was considered statistically insignificant. The number of patients who received transfusions was four patients in both groups and all received two units of red blood cells. CONCLUSION: the post operative serum hemoglobin levels, as well as the need of blood transfusion, in the patient underwent to total knee replacement, where the ischemia was released before wound closure, has no statistical effect in comparison with patients where the sutures and bandages were done after the ischemia release. Level of Evidence IB - Individual randomized controlled trial with narrow confidence interval. .


OBJETIVO: Avaliar comparativamente a perda sanguínea em pacientes submetidos à artroplastia total do joelho, com liberação da isquemia antes e após suturas e curativo compressivo. MÉTODOS: Fez-se um estudo prospectivo randomizado em 40 pacientes submetidos à artroplastia total do joelho divididos em dois grupos. No primeiro grupo a isquemia foi liberada antes do fechamento da ferida operatória, o que permitiu o controle do sangramento. No segundo a isquemia foi liberada após suturas e curativo compressivo. Foram comparados os resultados dos níveis de hemoglobina sérica antes da cirurgia e em 48 horas do pós-operatório, o volume sanguíneo contido no dreno de sucção a vácuo nesse período e a quantidade de transfusões de sangue que foram necessárias. RESULTADOS: Os níveis de hemoglobina pós-operatória tiveram uma diminuição média de 3,57g∕dL no grupo A e de 4,24g∕dL no grupo B, consideradas estatisticamente insignificantes (p = 0,23). Quatro pacientes nos dois grupos receberam duas unidades de concentrado de hemácias, sendo a diferença entre as médias drenado foram considerados estatisticamente insignificantes, para os grupos estudados. CONCLUSÃO: A concentração de hemoglobina sérica pós-operatória, bem como a necessidade de hemoderivados, nos pacientes submetidos à artroplastia total do joelho, na qual a liberação da isquemia foi deflagrada antes do fechamento da ferida operatória, não tem significância estatística quando comparada com a dos pacientes em que essa liberação foi feita após suturas e cultivado. Nivel de evidencia IB - Ensaio clínico controlado e rendomizado com intervalo de confiança estreito. .

ABSTRACT

OBJETIVO: Avaliar a perda sanguínea em pacientes submetidos à artroplastia total cimentada do joelho com e sem soltura trans-operatória do torniquete pneumático para a hemostasia. MÉTODOS: Foram estudados 72 pacientes submetidos à artroplastia total, num total de 80 joelhos, divididos em dois grupos: Grupo 1 onde se manteve o torniquete pneumático até a sutura e curativo da ferida operatória, e Grupo 2 onde foi realizada a soltura do torniquete pneumático após a cimentação da prótese, com realização de hemostasia direta, antes da sutura e curativo. Os pacientes foram avaliados quanto ao sangramento pelo dreno de sucção e à contagem de hemoglobina e hematócrito, considerando os intervalos de duas, 24 e 48 horas de pós-operatório. RESULTADOS: Não houve diferença significante entre os dois grupos quanto ao sangramento pós-operatório e decréscimo dos parâmetros hematimétricos. Somente um paciente do Grupo 2 necessitou transfusão de concentrado de hemáceas no pós-operatório. CONCLUSÃO: O sangramento pós-operatório na ATJ mostrou-se igual com e sem a soltura do torniquete pneumático para a realização da hemostasia.


OBJECTIVE: To evaluate blood loss in patients submitted to cemented total knee arthroplasty with and without perioperative tourniquet release for hemostasis. METHODS: Seventy-two patients (eighty knees) were submitted to total knee arthroplasty, allocated into two groups: in Group 1, in which the pneumatic tourniquet was maintained until suture and dressing of the operated wound, and Group 2, in which the pneumatic tourniquet was released intraoperatively after cementing the prosthesis, with direct hemostasis, before the suture and dressing. The patients were evaluated for blood loss by the suction drain, and hemoglobin and hematocrit counts, at intervals of 2, 24 and 48 hours in the postoperative period tube. RESULTS: There was no significant difference between the groups in terms of postoperative blood loss or decrease in hemoglobin and hematocrit parameters. Only one patient, from Group 2, required a blood transfusion in the postoperative period. CONCLUSION: Postoperative blood loss in TKA was similar with and without perioperative release of the pneumatic tourniquet for hemostasis.

ABSTRACT

OBJECTIVE: The objective of this review was to systematically analyze the trials on the effectiveness of perioperative warming in surgical patients. METHODS: A systematic review of the literature was undertaken. Clinical trials on perioperative warming were selected according to specific criteria and analyzed to generate summative data expressed as standardized mean difference (SMD). RESULTS: Twenty-five studies encompassing 3,599 patients in various surgical disciplines were retrieved from the electronic databases. Nineteen randomized trials on 1785 patients qualified for this review. The no-warming group developed statistically significant hypothermia. In the fixed effect model, the warming group had significantly less pain and lower incidence of wound infection, compared with the no-warming group. In the random effect model, the warming group was also associated with lower risk of post-anesthetic shivering. Both in the random and the fixed effect models, the warming group was associated with significantly less blood loss. However, there was significant heterogeneity among the trials. CONCLUSION: Perioperative warming of surgical patients is effective in reducing postoperative wound pain, wound infection and shivering. Systemic warming of the surgical patient is also associated with less perioperative blood loss through preventing hypothermia-induced coagulopathy. Perioperative warming may be given routinely to all patients of various surgical disciplines in order to counteract the consequences of hypothermia.


OBJETIVO: O objetivo desta revisão é analisar sistematicamente os ensaios sobre a eficácia do aquecimento perioperatório em pacientes cirúrgicos. MÉTODOS: Uma revisão sistemática da literatura foi realizada. Ensaios clínicos sobre aquecimento perioperatório foram selecionados segundo critérios específicos e analisados para gerar dados sumativo expresso na diferença média padronizada (standardized mean difference, SMD). RESULTADOS: Vinte e cinco estudos englobando 3.599 pacientes de várias disciplinas de cirurgia foram obtidos a partir de bases de dados eletrônicas. Dezenove ensaios aleatórios em 1.785 pacientes qualificados para esta revisão. Nenhum grupo de aquecimento desenvolveu estatisticamente significativa hipotermia. No modelo de efeito fixo, grupo de aquecimento tiveram significativamente menos dor e menor incidência de infecção na ferida quando comparado com o grupo de não-aquecimento. No modelo de efeito aleatório, grupo de aquecimento também foi associado a um menor risco de tremores pós-anestesia. Em ambos os modelos de efeitos fixos e aleatórios, o aquecimento foi significativamente associado com menor perda de sangue. No entanto, houve significativa heterogeneidade entre os ensaios. CONCLUSÃO: O aquecimento perioperatório de pacientes cirúrgicos é eficaz na redução da dor pós-operatória ferida, infecção ferida, e tremores. O aquecimento sistêmico do paciente cirúrgico também está associado com menor perda de sangue no perioperatório prevenindo hipotermia e induzindo coagulopatia. O aquecimento perioperatório pode ser administrado rotineiramente a todos os pacientes cirúrgicos de diversas disciplinas, a fim de neutralizar as consequências da hipotermia.
