Resumo Justificativa e objetivos O número de cirurgias laparoscópicas feitas tem aumentado a cada ano e, na maioria dos casos, o método com pneumoperitônio é o escolhido. Uma opção é o método de elevação da parede abdominal. Este estudo foi feito para avaliar as alterações da capacidade residual funcional durante o procedimento de elevação da parede abdominal. Métodos De janeiro a abril de 2013, 20 pacientes foram submetidos à colecistectomia laparoscópica em uma única instituição. Todos foram anestesiados com propofol, remifentanil e rocurônio. A CRF foi medida automaticamente com o Engström Carestation antes da elevação da parede abdominal e, novamente, 15 minutos após o início do procedimento. Resultados Após elevar a parede abdominal, um aumento significativo foi observado nos valores da capacidade residual funcional (antes da elevação da parede abdominal: 1,48 × 103 mL: após a elevação da parede abdominal: 1,64 × 103 mL) ( p <0,0001). Não houve complicações, como dessaturação, em nenhum paciente durante este estudo. Conclusões A cirurgia laparoscópica com elevador da parede abdominal pode ser apropriada para pacientes com fatores de risco como obesidade e doenças respiratórias. Background and objectives The number of laparoscopic surgeries performed is increasing every year and in most cases the pneumoperitoneum method is used. One alternative is the abdominal wall lifting method and this study was undertaken to evaluate changes of functional residual capacity during the abdominal wall lift procedure. Methods From January to April 2013, 20 patients underwent laparoscopic cholecystectomy at a single institution. All patients were anesthetized using propofol, remifentanil and rocuronium. FRC was measured automatically by Engstrom Carestation before the abdominal wall lift and again 15 minutes after the start of the procedure. Results After abdominal wall lift, there was a significant increase in functional residual capacity values (before abdominal wall lift 1.48 × 10 3 mL, after abdominal wall lift 1.64 × 10 3 mL) ( p < 0.0001). No complications such as desaturation were observed in any patient during this study. Conclusions Laparoscopic surgery with abdominal wall lift may be appropriate for patients who have risk factors such as obesity and respiratory disease. [ABSTRACT FROM AUTHOR]
