ABSTRACT

AbstractObjective:The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting.Methods:A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden) heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11.Results:The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump) as compared to Group 2 (off-pump). But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893), P>0.05 for bilateral pleural effusion (P=0.780)]. Left pleural effusion was encountered to be lower in Group 2 (off-pump). The difference was found to be statistically significant (P<0.05, P=0.006).Conclusion:Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.


ResumoIntrodução:O presente estudo investigou efeito da utilização de bomba em derrame pleural pós-operatório nos casos de pacientes que se submeteram à cirurgia de revascularização miocárdica.Métodos:Um total de 256 pacientes que foram submetidos à cirurgia de revascularização isolada no ambulatório de Cirurgia Cardiovascular foram incluídos no estudo. Máquina coração-pulmão Jostra-Cobe (Modelo 043213 105, VLC 865, Suécia) foi utilizada em cirurgia de revascularização miocárdica com circulação extracorpórea. Cirurgia de revascularização miocárdica sem circulação extracorpórea foi realizada utilizando Octopus e Starfish. Anastomose proximal na aorta, em ambas as técnicas, foi realizada por grampos laterais. Os pacientes receberam alta do hospital entre os dias 6 e 11 de pós-operatório.Resultados:A incidência de derrame pleural à direita pós-operatória e derrame pleural bilateral encontrada foi mais elevada em contagem do Grupo 1 (com circulação extracorpórea) em relação ao Grupo 2 (sem circulação extracorpórea). Mas a diferença não foi estatisticamente significativa [P>0,05 para derrame pleural à direita (P=0,893), P>0,05 para derrame pleural bilateral (P=0,780)]. O derrame pleural esquerdo encontrado foi menor no Grupo 2 (CEC). A diferença foi estatisticamente significativa (P<0,05, P=0,006).Conclusão:Sob a luz destes resultados, pode-se dizer que derrame pleural esquerdo é menos prevalente nos pacientes que foram submetidos à revascularização do miocárdio sem circulação extracorpórea em comparação com os pacientes que foram submetidos à revascularização do miocárdio com circulação extracorpórea.

ABSTRACT

OBJECTIVES: To review the evolution of off-pump coronary artery bypass surgery with particular reference to the anaesthetic and perioperative implications. FINDINGS: After review of the literature regarding coronary artery bypass grafting, the adverse effects of cardiopulmonary bypass on the various systems are discussed The development and the present status of off-pump coronary artery bypass surgery and its anaesthetic implications are reviewed These are discussed under the categories of preoperative, intra-operative and postoperative concerns. In Trinidad and Tobago, various cardiac surgical teams from different parts of the world conduct cardiac surgery. The cardiac anaesthesia team therefore has the unique opportunity of working with several teams who employ different techniques. CONCLUSIONS: Off-pump coronary artery bypass grafting surgery has distinct anaesthetic implications. In Trinidad and Tobago, the majority (85%) of the coronary revascularization surgeries are being done by this technique. Because of the lower cost and improved outcomes, this technique could be recommended to other developing countries of the region.


Objetivos: Examinar la evolución de la cirugía de bypass coronario (revascularización coronaria) sin circulación extracorpórea, con referencia particular a las implicaciones anestésicas y perioperatorias. Hallazgos: Tras examinar la literatura en relación con el bypass coronario con injerto, se discuten los efectos adversos del bypass cardiopulmonar en los distintos sistemas. Se analiza el desarrollo y el estatus presente de la cirugía de bypass coronario sin circulación extracorpórea (“sin bomba”) y sus implicaciones anestésicas. El análisis se realiza bajo las categorías de problemas pre-operatorios, intra-operatorios y post-operatorios. En Trinidad y Tobago, varios equipos de cirugía cardiaca de diferentes partes del mundo llevan a cabo cirugía cardiaca. Por lo tanto, el equipo que tiene a su cargo la anestesia durante las intervenciones quirúrgicas del corazón tiene la oportunidad excepcional de trabajar con varios equipos que emplean diferentes técnicas. Conclusiones: La cirugía de injerto de bypass coronario sin circulación extracorpórea tiene claras implicaciones anestésicas. En Trinidad y Tobago, la mayoría (85%) de las cirugías de revascularización coronaria, se realizan mediante esta técnica. Debido a su bajo costo y al mejoramiento en sus resultados, esta técnica podría recomendarse a los países en desarrollo de la región.
