Resumo

Experiência e objetivos: a cistectomia robótica vem rapidamente se tornando parte do repertório cirúrgico de rotina para o tratamento do câncer de próstata. Nosso objetivo foi descrever os desafios respiratórios e hemodinâmicos e as complicações observadas em pacientes de cistectomia robótica. Pacientes: foram prospectivamente recrutados 16 pacientes tratados com cistectomia robótica entre dezembro de 2009 e janeiro de 2011. As medidas de desfecho primário foram monitoração não invasiva, monitoração invasiva e análise de gases sangüíneos feita nas posições supina (T0), Trendelenburg (T1), Trendelenburg + pneumoperitônio (T2), Trendelenburg antes da dessuflação (T3), Trendelenburg depois da dessuflacão (T4) e supina (T5). Resultados: houve diferencas significativas entre T0 - T1 e T0 - T2 com frequências cardíacas mais baixas. O valor médio para a pressão arterial em T1 foi significativamente mais baixo do que em T0. O valor da pressão venosa central foi significativamente mais elevado em T1, T2, T3 e T4 versus T0. Não foi observada diferença significativa no valor de PET-CO2 em qualquer ponto temporal, em comparação com T0. Também não foram notadas diferenças significativas na frequência respiratória em qualquer ponto temporal, em comparação com T0. Os valores médios de ƒ em T3, T4 e T5 foram significativamente mais elevados versus T0. A ventilação minuto média em T4 e T5 foi significativamente mais elevada versus T0. As pressões de platô e de pico médias em T1, T2, T3, T4 e T5 foram significativamente mais elevadas versus T0. Conclusões: embora a maioria dos pacientes geralmente tolere satisfatoriamente a cistectomia robótica e perceba os benefícios, os anestesiologistas devem levar em consideração as mudanças no sistema cardiopulmonar ocorrentes quando os pacientes são colocados na posição de Trendelenburg e ao ser criado um pneumoperitônio.

Abstract

Background and objectives: Robotic cystectomy is rapidly becoming a part of the standard surgical repertoire for the treatment of prostate cancer. Our aim was to describe respiratory and hemodynamic challenges and the complications observed in robotic cystectomy patients. Patients: Sixteen patients who underwent robotic surgery between December 2009 and January 2011 were prospectively enrolled. Main outcome measures were non-invasive monitoring, invasive monitoring and blood gas analysis performed at supine (T0), Trendelenburg (T1), Trendelenburg + pneumoperitoneum (T2), Trendelenburg-before desufflation (T3), Trendelenburg (after desufflation) (T4), and supine (T5) positions. Results: There were significant differences between T0 - T1 and T0 - T2 with lower heart rates. The mean arterial pressure value at T1 was significantly lower than T0. The central venous pressure value was significantly higher at T1, T2, T3, and T4 than at T0. There was no significant difference in the PET-CO2 value at any time point compared with T0. There were no significant differences in respiratory rate at any time point compared with T0. The mean ƒ values at T3, T4, and T5 were significantly higher than T0. The mean minute ventilation at T4 and T5 were significantly higher than at T0. The mean plateau pressures and peak pressures at T1, T2, T3, T4, and T5 were significantly higher than the mean value at T0. Conclusions: Although the majority of patients generally tolerate robotic cystectomy well and appreciate the benefits, anesthesiologists must consider the changes in the cardiopulmonary system that occur when patients are placed in Trendelenburg position, and when pneumoperitoneum is created.
