ABSTRACT

RESUMO Desde a instituição da circulação extracorpórea, há cinco décadas, a lesão cerebral decorrente desse procedimento durante cirurgias cardiovasculares tem sido uma complicação frequente. Não existe uma causa única de lesão cerebral pelo uso de circulação extracorpórea, porém se sabe que acomete cerca de 70% dos pacientes submetidos a esse procedimento. A avaliação da pressão intracraniana é um dos métodos que podem orientar os cuidados com os pacientes submetidos a procedimentos associados com distúrbios neurológicos. Este artigo descreve dois casos de pacientes submetidos à cirurgia cardiovascular com circulação extracorpórea, para os quais os procedimentos de neuroproteção na fase pós-operatória foram guiados pelos achados relacionados ao formato das ondas de pressão intracraniana, obtidos por meio de um método não invasivo de monitoramento.


ABSTRACT Brain injury caused by extracorporeal circulation during cardiovascular surgical procedures has been a recurring complication since the implementation of extracorporeal circulation five decades ago. There is no unique cause of brain injury due to the use of extracorporeal circulation, but it is known that brain injury affects about 70% of patients who undergo this procedure. Intracranial pressure assessment is one method that can guide the management of patients undergoing procedures associated with neurological disturbances. This study describes two cases of patients who underwent cardiovascular surgery with extracorporeal circulation in whom clinical protocols for neuroprotection in the postoperative phase were guided by intracranial pressure waveform findings obtained with a novel noninvasive intracranial pressure monitoring method.

ABSTRACT

ANTECEDENTES: El reemplazo protésico de la válvula tricúspide es un procedimiento infrecuente, con elevada mortalidad y morbilidad operatoria, independientemente de la etiología de la insuficiencia tricuspídea. Persiste aún una discusión respecto al tipo de prótesis a utilizar, mecánica o biológica. OBJETIVO: Analizar nuestros resultados perioperatorios y alejados en el reemplazo valvular tricuspídeo, comparando ambos tipos de prótesis. MÉTODO: Revisión de la Base de Datos de nuestro Servicio de Cirugía Cardiovascular para el periodo enero 1991 - diciembre 2017. Identificados los pacientes con reemplazo valvular tricuspídeo (RVT); se revisaron los protocolos operatorios y los ecocardiogramas. La supervivencia se certificó a través del Registro Civil e Identificación de Chile. RESULTADOS: Se identificaron 83 pacientes con RVT (76% mujeres), los que representaron el 0,7% del total de las cirugías con circulación extracorpórea y el 2,1% de las cirugías valvulares para el periodo en estudio. La edad promedio fue 49±16,5 años. Cuarenta y nueve casos (59%) correspondieron a reoperaciones y otros 49 tuvieron un procedimiento asociado. En 40 pacientes (48%) se utilizó una prótesis mecánica y en 43 (52%) una biológica. La mortalidad operatoria global fue 9,6% (8 pacientes, 4 con una prótesis mecánica y 4 con una biológica). El seguimiento se completó en el 100%, con un promedio de 7,1 años. Veintiocho pacientes fallecieron durante el seguimiento; la principal causa fue insuficiencia cardiaca. Así, la supervivencia a 5 años fue 70,3 ± 5,3% y a 10 años 58 ± 6,3%, sin diferencia significativa entre ambos tipos de prótesis. Siete pacientes se reoperaron durante el seguimiento (5 casos con prótesis biológica y 2 mecánica). CONCLUSIÓN: El RVT continúa siendo un procedimiento infrecuente, con mayor incidencia en mujeres, en la quinta década de la vida. La mayoría de los pacientes presentaba comorbilidad y había tenido cirugía cardiovascular previa. La mitad de estos recibió una prótesis mecánica y la otra, biológica. No hubo diferencias significativas entre ambos tipos de prótesis en cuanto a mortalidad operatoria, supervivencia alejada o reoperación.


BACKGROUND: Tricuspid valve replacement (TVR) is an uncommon surgical procedure, associated with high mortality and morbidity. The use of biological or mechanical prostheses in TVR has advantages and disadvantages and, therefore, there persists a debate regarding the choice of one or other type of prostheses. AIM: To analyze our operative and long-term surgical results, comparing both types of prosthetic valves. METHODS: The Data Base of the Cardiovascular Surgery Service was reviewed for the period between January 1991 and December 2017. 83 patients with TVR were identified, the operative notes and echocardiogram reports were analyzed. Survival was obtained from the Chilean Civil Identification Service. RESULTS: 83 patients (76% women) had TVR. They represented 0.7% of the total cases operated on with extracorporeal circulation and 2.1% of all valve disease cases, for the study period. Mean age was 49±16.5 years. 49 cases (59%) were reoperations and another 49 had an associated procedure. In 40 patients (48%) a mechanical prosthesis was used and in 43 (52%) a biological one was implanted. Operative mortality rate was 9.6% (8 patients, had a mechanical valve and the other 8, a biological one). Follow-up was 100% completed, with an average of 7.1 years. 28 patients died during follow-up; the main cause of death was heart failure. Five-year survival rate was 70.3 ± 5.3% and at 10 years it was 58 ± 6.3%, without significant difference the type of prostheses. Seven patients were re-operated during follow-up (5 cases corresponded to a biological prostheses and 2 to a mechanical one). CONCLUSION: TVR is still an infrequent surgical procedure, more commonly performed in women, on the fifth decade of life. Most patients presented comorbidities and had a previous cardiovascular surgical operation. Half of them received a mechanical prosthesis and half a biological one. There was no significant difference between both types of prostheses related to surgical mortality, long-term survival or reoperation.

ABSTRACT

Objective: to determine the microbiological characteristics of the red blood cells obtained with the cell saver in heart surgery patients on an extra-body circuit. Method: a cross-sectional and descriptive study conducted with 358 patients scheduled for heart surgery where the saver was used. Sociodemographic variables were collected, as well as from the saver and of the microbial identification in the re-infusion bag proceeding from the cell saver. Informed consent performed. Results: of the 170 GRAM+ bacteria isolations, the most frequent species were Staphylococcus epidermidis in 69% (n=138) of the cases and Streptococcus sanguinis with a report of 10% (n=20). Significant differences were found in the Staphylococcus epidermidis strain in patients with a Body Mass Index ≥25 (p=0.002) submitted to valve surgery (p=0.001). Vancomycin was the antimicrobial which resisted the Staphylococcus epidermidis strain with a minimum inhibitory concentration of >16 µg/ml. Conclusion: the microbiological characteristics of the red blood cells obtained after processing autologic blood recovered with the cell saver during heart surgery are of GRAM+ bacterial origin, the most isolated species being Staphylococcus epidermidis. Consequently, in order to reduce the presence of these GRAM+ cocci, an antibiotic should be added to the cell saver reservoir, according to a previously established protocol.


Objetivo: determinar as características microbiológicas dos glóbulos vermelhos obtidos com o "cell saver" em pacientes submetidos à cirurgia cardíaca em circuito extracorpóreo. Método: estudo descritivo transversal com 358 pacientes de cirurgia cardíaca em que o "cell saver" foi utilizado. Foram coletadas variáveis sociodemográficas e identificação microbiana da bolsa de reinfusão do "cell saver". Foi confirmado o Termo de Consentimento. Resultados: das 170 baterias isoladas GRAM+, as mais frequentes foram Staphylococcus epidermidis em 69% (n=138) dos casos e Streptococcus sanguinis com um registro de 10% (n=20). Diferenças significativas foram encontradas na cepa Staphylococcus epidermidis em pacientes com índice de massa corporal ≥25 (p=0,002) submetidos a cirurgia valvular (p=0,001). A vancomicina foi o antimicrobiano resistente à cepa Staphylococcus epidermidis com uma concentração inibitória mínima >16 µg/ml. Conclusão: as características microbiológicas dos glóbulos vermelhos obtidas após o processamento do sangue autólogo recuperado com o "cell saver" em cirurgia cardíaca são de origem bacteriana GRAM+, sendo a espécie mais isolada o Staphylococcus epidermidis. Portanto, para reduzir a presença desses cocos GRAM+, um antibiótico deve ser adicionado ao "cell saver", de acordo com um protocolo previamente estabelecido.

Método: estudio descriptivo transversal con 358 pacientes programados para cirugía cardíaca donde se utilizó el "cell saver". Se recogieron variables sociodemográficas e identificación microbiana de la bolsa de reinfusión procedente del "cell saver". Consentimiento informado realizado. Resultados: de 170 aislamientos de bacterias GRAM+, las especies más frecuentes fueron el Staphylococcus epidermidis en el 69% (n=138) de los casos y el Streptococcus sanguinis con un reporte del 10% (n=20). Se encontraron diferencias significativas en la cepa Staphylococcus epidermidis en pacientes con índice de masa corporal ≥25 (p=0,002) sometidos a cirugía valvular (p=0,001). La vancomicina fue el antimicrobiano resistente a la cepa Staphylococcus epidermidis con una concentración mínima inhibitoria >16 ug/ml. Conclusión: las características microbiológicas de los glóbulos rojos obtenidos tras el procesamiento de sangre autóloga recuperada con el "cell saver" en cirugía cardíaca son de origen bacteriano GRAM+ siendo la especie más aislada el Staphylococcus epidermidis. Por ello, con el fin de reducir la presencia de estos cocos GRAM+ se debería añadir un antibiótico en el reservorio del "cell saver", según un protocolo previamente establecido.

ABSTRACT

Objetivo: Verificar as principais complicações da cirurgia de revascularização do miocárdio (RM) com circulação extracorpórea (CEC) e sua associação com os fatores de risco modificáveis e não modificáveis, diagnósticos de enfermagem, tempo de CEC e carga horária de enfermagem. Método: Coorte retrospectiva por meio da análise de 50 prontuários de pacientes adultos submetidos à RM com CEC, entre 2012 e 2017. Projeto aprovado pelo Comitê de Ética em Pesquisa parecer nº 1969823. Resultados: A amostra foi predominantemente masculina (70%), com idade média de 62,1 anos (desvio padrão ­ DP±9,98). O tempo médio de CEC foi de 124 minutos (DP±0,46). Complicações pós-operatórias ocorreram em 52% dos 50 pacientes analisados, sendo a mais frequente o sangramento (16%). O diagnóstico de enfermagem mais frequente foi risco de infecção (92%). Constatou-se que os cuidados pela equipe de enfermagem foram mais requeridos por pacientes que apresentaram hipotensão (p=0,003) e arritmia (p=0,000) no pós-operatório. Conclusão: O conhecimento das complicações pós-operatórias associadas ao perfil dos pacientes atendidos colabora para a elaboração de planos de cuidados mais adequados

ABSTRACT

Los aneurismas del cayado aórtico representan un desafío, ya que el involucramiento de sus grandes ramas exige una técnica quirúrgica compleja. A partir de la aparición del tratamiento endovascular, una alternativa desarrollada en los últimos años para abordar el cayado aórtico consistió en el tratamiento híbrido de esta patología, mediante la derivación quirúrgica de los vasos del cuello y la posterior exclusión del aneurisma con una endoprótesis. Este método híbrido es conocido con el nombre de debranching, y en forma simplificada consiste en realizar, sin circulación extracorpórea, una serie de puentes entre la aorta ascendente y el tronco braquiocefálico, la arteria carótida izquierda y eventualmente la arteria subclavia izquierda, para permitir avanzar una endoprótesis que cubra toda la luz del aneurisma. Se describe la técnica quirúrgica del debranching híbrido tipo I, sin el auxilio de la circulación extracorpórea e implante anterógrado de la endoprótesis, para los aneurismas del cayado aórtico.


Aortic arch aneurysms represent a major challenge as the involvement of the supra-aortic vessels demands a complex surgical technique. Since the advent of endovascular aortic repair, hybrid treatment of aortic arch disease has emerged in recent years. The procedure consists of surgical bypass of the supra-aortic vessels followed by exclusion of the aneurysm with an endograft. This hybrid method is known as debranching and, briefly, consists in performing bypasses between the ascending aorta and the brachiocephalic artery, the left carotid artery and possibly the left subclavian artery without cardiopulmonary bypass, in order to advance an endograft to cover the entire lumen of the aneurysm. The aim of this paper is to describe the surgical technique of type I hybrid debranching without cardiopulmonary bypass and antegrade endograft delivery to treat aortic arch aneurysms.

ABSTRACT

Abstract Introduction: The true influence of the low mean arterial pressure (low MAP) during coronary artery bypass grafting (CABG) on the development of postoperative cognitive deficit (POCD) remains controversial. We aimed to perform a meta-analysis and meta-regression to determine the effect of low MAP on POCD, as well as moderator variables between low MAP and POCD. Methods: The Web of Science, PubMed database, Scopus and the Cochrane Library database (up to June 2018) were searched and retrieved articles systematically reviewed. Only randomized controlled trials (RCTs) comparing maintenance of low MAP (<80 mmHg) and high MAP (>80 mmHg) during cardiopulmonary bypass (CPB) were included in our final review. Statistical analysis of the risk ratio (RR) and corresponding 95% confidence interval (CI) was used to report the overall effect. The overall effect and meta-regression analysis were done using Mantel-Haenszel risk ratio (MHRR) and the corresponding 95% confidence interval (CI). Results: A total of 731 patients in three RCTs were included in this study. POCD occurred in 6.4% of all cases. Maintenance of low MAP did not reduce the occurrence of POCD (MHRR 1.012 [95% CI 0.277-3.688]; Z=0.018; P=0.986; I2=66%). Shorter CPB time reduced the occurrence of POCD regardless of group assignment (MH log risk ratio -0.519 [95% CI -0.949 - -0.089]; Z= -2.367; P=0.017). Conclusion: POCD is a common event among CABG patients. The neuroprotective effect of low MAP on POCD was attenuated by the prolonged CPB time.

ABSTRACT

Background Robot-assisted minimally invasive heart surgery is an effective alternative when compared with classical approaches. It has a low mortality and postoperative complications and its long-term durability is comparable with conventional techniques. Aim: To report short- and long-term results with the use of a robot-assisted transthoracic approach. Patients and Methods: Review of patients undergoing heart surgery between 2015 and 2019 using a robot assisted minimally invasive technique in a single center. We analyzed demographic characteristics, surgical and early ultrasound results. Results: Thirteen procedures were reviewed, nine mitral valve repairs (MVR) in patients aged 61 ± 21 years (seven males) and four atrial septal defect (ASD) closures in patients aged from 24 to 52 years (three men). For MVR, the average extracorporeal circulation and myocardial ischemia times were 120 ± 20.9 and 89 ± 21 minutes, respectively. The median hospitalization was four days. Two cases of MVR had postoperative complications. There was no mortality. All cases showed improvement in their symptoms. Ultrasound findings showed no postoperative mitral insufficiency except in one case. Conclusions: We report very good results in both complex mitral repair and CIA closure, comparable to centers with high standards in minimally invasive robot-assisted heart surgery.

Se realizó técnica de Propensity Score Matching para identificar grupos de pacientes similares y comparar resultados entre ambas técnicas. RECSULTADOS: Mortalidad operatoria en 1,0% en el grupo sin CEC y 2,1% en el grupo con CEC (p = 0,411). En seguimiento alejado: Supervivencia a 1, 3 y 5 años de 97,4%, 95,3% y 92,2% respectivamente sin CEC vs 97,9%, 96,3% y 92,7% respectivamente con CEC (p = 0,824). Mayor-Adverse-Cardiac-and-Cerebrovascular-Events (MACCE) 28 (17,3%) sin CEC vs 26 (16,0%) (p = 0,71). Infarto agudo al miocardio (IAM) 3 (1,9%) sin CEC vs 6 (3,7%) (p = 0,33), accidente vascular encefálico (AVE) 6 (3,7%) sin CEC vs 3 (1,9%) (p = 0,3) y reintervención 4 (2,5%) sin CEC vs 3 (1,9%) (p = 0,703). Recurrencia de angina 9 (5,6%) sin CEC vs 10 (6,2%) (p = 0,813). CONCLUSIONES: En nuestra serie de paciente ambas técnicas fueron comparables en resultados inmediatos y alejados.


INTRODUCTION: Coronary artery bypass grafting (CABG) without extracorporeal circulation (off pump) is a technical alternative to conventional surgery. There is ongoing controversy about its benefits, safety and results. AIM: To describe immediate and late results of off pump CABG and compare it with conventional surgery. MATERIALS AND METHOD: Descriptive-analytic, study with review of surgical protocols, clinical charts, civil registry for survival and telephonic follow up of patient who underwent CABG in our center between January 2006 and December 2008. In total 658 isolated CABG cases, 466 (70.8%) on pump and 192 (29.2%) off pump. A Propensity Score Matching was used to match off pump CABG patients with those undergoing On Pump CABG. RESULTS: Mortality was 1.0% in off pump and 2.1% in on pump patients (p = 0.411). At follow up: 1.3 and 5 year survival was 97.4%, 95.3% and 92.2% respectively in off pump patients and 97.9%, 96.3% and 92.7% respectively in On Pump patients (p = 0.824). Mayor-adverse-Cardiac-and-Cerebrovascular-events (MACCE) in 28 (17.3%) off pump vs 26 (16.0%) (p = 0.71) on pump, myocardial infarction in 3 (1.9%) off pump vs 6 (3.7%) on pump (p = 0.33), stroke in 6 (3.7%) off pump vs 3 (1.9%) on pump (p = 0.3) and coronary reintervention in 4 (2.5%) off pump vs 3 (1.9%) on pump patients (p = 0.703). Recurrence of angina in 9 (5.6%) off pump vs 10 (6.2%). CONCLUSIONS: In our experience both techniques had similar results.

To describe the presence of short stature among children undergoing cardiac surgery for CHDs. Population and methods. Retrospective study. Children undergoing cardiac surgery with cardiopulmonary bypass pump between 2009 and 2013 were included. Preterm infants, carriers of genetic syndromes or other disease with nutritional compromise were excluded. Demographic data, type of CHD, admission surgery and anthropometric assessment using the WHO standards were studied. Short stature was defined as lenght/height for age Z score < -2 standard deviations, by sex. Results. A total of 640 children were studied; 361 (56.4 %) were boys; median age: 8 months (IQR: 1.9; 34.6); 66 children underwent > 1 surgery; 27 of them (40.9 %) had hypoplasia of the left ventricle. There were 358 (55.9 %) infants with cyanotic CHDs, 196 (30.6 %) with univentricular physiology. The median HAZ was -0.9 (IQR: -1.9; -0.1); 135 (21.1 %) had a short stature, 11 % of newborn infants and 24.1 % of older than one month old. A higher frequency of short stature was observed in 4 out of 6 children who underwent complete repair of the atrioventricular canal, in 15 out of 39 infants with repair of tetralogy of Fallot, in 8 out of 25 infants with hypoplasia of the left ventricle subjected to Glenn procedure, and in 34 out of 103 with closure of the ventricular septal defect. No association or statistically significant difference was found between short stature and cyanosis or univentricular physiology. Conclusions. There is a high frequency of short stature among children with CHDs, with differences according to the type of CHD and cardiac surgery performed.

ABSTRACT

Objetivos: Describir los resultados actuales en cirugía cardiovascular de pacientes portadores de cardiopatía congénita (CC) intervenidos con circulación extracorpórea (CEC) en menores de un año de vida. Métodos: Se incluyeron todos los pacientes operados de cirugía cardiovascular (CCV) en el Hospital de Pediatría Juan P. Garrahan en el periodo comprendido 2004-2017. Se analizaron los resultados actuales en términos de morbi-mortalidad de neonatos y lactantes menores de 1 año que requirieron cirugía precoz. Se excluyeron todos los pacientes operados que no requirieron cirugía con CEC y aquellos operados que ingresaron al Área de Neonatología. El análisis de mortalidad fue realizado por riesgo estratificado con la escala de RACHS-1. Los datos se obtuvieron de la base de datos de la Unidad de Recuperación Cardiovascular (UCI 35). Resultados: El número anual de pacientes intervenidos en cirugía cardiovascular ha presentado un incremento persistente desde sus comienzos. En el año 2004 se registraron 448 casos y a partir del año 2014, en forma persistente, los pacientes intervenidos superan las 500 cirugías anuales de cardiopatías. A inicios del 2004 el 75% de las cirugías totales eran con CEC, mostrando un ascenso significativo que alcanzo el 89% durante los últimos años. Los menores de 1 años representan más del 50% de las cirugías y en promedio un 15% son neonatos. También se evidenció un importante incremento de cirugías en cardiopatías más complejas, pero se mantuvo un número estable para aquellas cirugías de complejidad intermedia. En la escala RACHS-1, el 55% de las intervenciones correspondieron a un score >3 y más del 10% para categorías 5-6. La mortalidad global fue entre 5- 6% de las cirugías realizadas, y un 15% para la cirugía neonatal. El 10% de los fallecidos eran portadores de síndromes genéticos o presentaban asociación con otras malformaciones mayores. Conclusiones: Es notorio el incremento anual en frecuencia de patologías de mayor severidad que son enfrentadas en forma precoz logrando modificar la historia natural de las cardiopatías complejas. Aumenta el riesgo de morbimortalidad en CC asociadas a síndrome genético y condición clínica desfavorable pre quirúrgica. La intervención quirúrgica correctora precoz mejoraría los resultados en término de crecimiento y desarrollo del niño portador de CC (AU)


Objectives: To describe the current results in cardiovascular surgery of patients with congenital heart defects (CHD) who underwent extracorporeal membrane oxygenation (ECMO) support at less than one year of life. Methods: All patients who underwent cardiovascular surgery (CVS) at the Juan P. Garrahan Pediatric Hospital between 2004 and 2017 were included. Current results regarding morbidity and mortality in neonates and infants under 1 year who required early surgery were analyzed. Patients who did not require ECMO postoperatively and those admitted to the neonatal intensive care unit were excluded. Mortality analysis was performed stratified by risk using the RACHS-1 scale. Data were obtained from the Cardiovascular Recovery Unit (ICU 35) database. Results: The annual number of patients undergoing cardiovascular surgery has steadily increased since its beginning. In 2004, 448 cases were reported and as of 2014, yearly more than 500 patients undergo heart surgery. At the beginning of 2004, 75% of all surgeries were with ECMO, significantly increasing to 89% over the last few years. Children under 1 years of age account for more than 50% of surgeries and around 15% are neonates. A significant increase in surgeries in more complex heart disease was also evident, but a stable number was maintained for those surgeries of intermediate complexity. On the RACHS-1 scale, 55% of the interventions were score >3 and more than 10% were scores 5-6. Overall mortality was between 5-6% of all surgeries performed, and 15% for neonatal surgery. Of the children who died, 10% were carriers of genetic syndromes or had other major malformations. Conclusions: There was a remarkable yearly increase in frequency of more severe conditions that are managed early, modifying the natural history of complex heart disease. In CHD associated with a genetic syndrome and an unfavorable pre-surgical clinical condition the risk of morbidity and mortality is increased. Early surgical intervention may improve outcomes in terms of the growth and development of the child with CHD (AU)

ABSTRACT

ABSTRACT BACKGROUND: The pleural drain insertion site after coronary artery bypass graft (CABG) surgery may alter lung function, especially respiratory muscle strength. The main objective of this study was to compare the effectiveness and safety of use of the left lateral intercostal region versus the subxiphoid position for pleural drainage during elective CABG surgery using extracorporeal circulation (ECC). DESIGN AND SETTING: Randomized trial conducted in a tertiary-level hospital in Porto Alegre, Brazil. METHODS: 48 patients were assigned to group 1 (pleural drain in the left lateral intercostal region) or group 2 (pleural drain in the subxiphoid position). Respiratory muscle strength was measured in terms of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP), in cmH2O, by means of manovacuometry preoperatively, 24 and 72 hours after drain removal and before discharge from hospital. Painand dyspnea scales, presence of infections, pleural effusion and atelectasis, duration of drain use, drainage volumes and surgical reinterventions were also evaluated. RESULTS: After adjustments, there were no significant differences between the groups at the end of the study (before discharge), in predicted percentages either for MIP (delta group 1: -17.21% versus delta group 2: -22.26%; P = 0.09) or for MEP (delta group 1: -9.38% versus delta group 2: -13.13%; P = 0.17). Therewere no differences between the groups in relation to other outcomes. CONCLUSION: There was no difference in maximal respiratory pressures in relation to the pleural drain insertion site among patients who underwent CABG surgery using ECC. TRIAL REGISTRATION: ReBEc V1111.1159.4447.

ABSTRACT

Fundamentos: A ventilação mecânica (VM) e a circulação extracorpórea (CEC) estão associadas a um declínio da mecânica pulmonar que pode impactar as trocas gasosas. Objetivo: Avaliar o impacto da mecânica pulmonar sobre a duração da VM e trocas gasosas no pós-operatório de cirurgia cardíaca. Métodos: Estudo de coorte realizado com pacientes submetidos a cirurgia cardíaca. Todos os pacientes foram submetidos a avaliação da mecânica pulmonar (complacência estática e resistência das vias aéreas) e gasometria arterial assim que admitidos à unidade de terapia intensiva (UTI) e foram acompanhados até o momento da extubação e, em seguida, até a alta hospitalar. Para correlacionar as variáveis preditoras com o desfecho, foi utilizado o teste de Pearson. Valores de p < 0,05 foram considerados significativos. Resultados: O estudo incluiu 50 pacientes (46 mulheres, 52%), com idade média de 57,5 ± 13,5 anos. A duração da VM foi de 7,7 ± 3,0 horas, a complacência estática foi de 35,5 ± 9,1 cm H2O, a resistência foi de 6,0 ± 2,3 cm H2O, a duração média de estadia na UTI foi de 2,9 ± 1,1 dias e o índice de oxigenação foi de 228,0 ± 33,4 mmHg. Não houve uma correlação significativa entre a duração da VM e a complacência estática (p = 0,73), porém houve uma forte correlação entre a complacência estática e as trocas gasosas (r = 0,8, p < 0,001). Conclusão: A mecânica pulmonar apresenta forte correlação com as trocas gasosas e fraca correlação com a duração da VM no pós-operatório de cirurgia cardíaca


Background: Mechanical ventilation (MV) and extracorporeal circulation (ECC) are associated with a decline in pulmonary mechanics that may affect gas exchange. Objective: To evaluate the impact of pulmonary mechanics on MV duration and gas exchange in the postoperative period of cardiac surgery. Methods: This was a cohort study in patients undergoing cardiac surgery. All patients underwent evaluation of pulmonary mechanics (static compliance and airway resistance) and arterial blood gas analysis upon admission to the intensive care unit (ICU) and were followed up until extubation and hospital discharge. Results: The study included 50 patients (46 women, 52%) with a mean age of 57.5 ± 13.5 years. The MV duration was 7.7 ± 3.0 hours, static compliance was 35.5 ± 9.1 cm H2O, resistance was 6.0 ± 2.3 cm H2O, mean length of ICU stay was 2.9 ± 1.1 days, and oxygenation index was 228.0 ± 33.4 mmHg. No significant correlation was found between MV duration and static compliance (p = 0.73), but a strong correlation was found between static compliance and gas exchange (r = 0.8 and p < 0.001). Conclusion: Pulmonary mechanics have a strong correlation with gas exchange and a weak correlation with MV duration after cardiac surgery

ABSTRACT

Abstract Objective: To compare the perioperative incidence rates of hemolysis and inflammatory response in patients undergoing coronary artery bypass grafting with the two main types of cardiopulmonary bypass, centrifugal and roller pumps, and establish correlations among hemolytic and inflammatory changes. Methods: This was a prospective, randomized trial of 60 patients assigned to either roller pump (G1, n=30) or centrifugal pump (G2, n=30) bypass. Markers of hemolysis (serum haptoglobin, lactate dehydrogenase [LDH]) and inflammation (interleukin [IL]1ß, IL-6, and TNF-α) were measured and analyzed. Results: There was no significant between-group difference in the variables of interest. In G1, there was a positive association with IL-6 and TNF-α (P<0.01 and P<0.05, respectively). In G2, there was a positive association with LDH in the postoperative period (P<0.5). At 24h post-cardiopulmonary bypass, there were positive associations between LDH and IL-1ß (P<0.05), LDH and TNF-α (P<0.01), haptoglobin and TNF-α (P<0.05), and LDH and TNF-α (P<0.01) in G1, and between LDH and IL-6 (P<0.01), LDH and TNF-α (P<0.01), and LDH and IL-6 (P<0.01) in G2. Conclusion: There were no significant between-group differences in markers of hemolysis or inflammation. IL-6 and TNF-α were positively associated with duration of cardiopulmonary bypass in G1, while LDH was positively associated with duration of cardiopulmonary bypass in G2. The rate of significant associations between markers of hemolysis and inflammation was higher in the roller pump group (G1). Registration number: ReBEC (RBR-92b9dg).
