title: [Anesthesia experiences on laparoscopic nephrectomy with da Vinci S robotics].
abstract: OBJECTIVE
  To summarize the clinical anesthesia experiences in 20 patients who underwent laparoscopic nephrectomy with da Vinci S robotics.
  
  
  METHODS
  Anesthesia data of 20 patients from Sichuan Provincial People's Hospital, who underwent laparoscopic nephrectomy with da Vinci S robotics from August 2014 to November 2014, were analyzed and summarized. The anesthesia time, operation time, CO(2) pneumoperitoneum time, PaCO(2) and PETCO(2) were recorded.
  
  
  RESULTS
  All patients were anesthetized and underwent surgery with da Vinci S robotics. The anesthesia time was (220±14) min, the operation time was (187±11) min, and the CO(2) pneumoperitoneum time was (180±13) min. The PaCO(2) and PETCO(2) were significantly elevated at 1.5 h after operation compared with those at the baseline (before pneumoperitoneum) (P<0.05). The pH value was significantly decreased at 2.5 h after operation compared to that at the baseline (P<0.05). The peak airway pressure of inspiration was significantly elevated at 0.5 h after the beginning of pneumoperitoneum compared to that at the baseline (P<0.05).
  
  
  CONCLUSIONS
  The hemodynamics is stable during the laparoscopic nephrectomy with da vinci S robotics. However, the duration of CO(2) pneumoperitoneum is significantly increased compared to that of other surgical procedures, resulting in high airway resistance and acid-base disturbance.
