AbstractWe investigated the abilities of pulse pressure variation (PPV) and stroke volume variation (SVV) to predict fluid responsiveness during robot-assisted laparoscopic prostatectomy, requiring pneumoperitoneum and the Trendelenburg position. In 42 patients without cardiopulmonary disease, PPV and SVV were measured before and after administration of 500 ml colloid under pneumoperitoneum combined with the steep Trendelenburg position (35°). Fluid responsiveness was defined as a ≥15% increase in stroke volume after the fluid loading measured using transoesophageal echocardiography. Of the 42 included patients, 22 were responders and 20 were non-responders. A PPV of ≥9.5% identified responders with a sensitivity of 77.3% and a specificity of 90.0%, and a SVV of ≥9.5% also identified responders with a sensitivity of 77.3% and a specificity of 75.0%. The area under receiver operating characteristic curves for PPV and SVV were 0.87 (P <0.001) and 0.81 (P=0.001), respectively. The findings suggest that both PPV and SVV could be useful predictors of fluid responsiveness in patients without cardiopulmonary disease undergoing robotic laparoscopic surgery with pneumoperitoneum in the Trendelenberg position.
