[Anesthesia experiences on laparoscopic nephrectomy with da Vinci S robotics]

Area of Science:

• Urology
• Anesthesiology
• Robotic Surgery

Background:

• Laparoscopic nephrectomy with robotic assistance is increasingly utilized.
• Understanding anesthesia implications is crucial for patient safety.

Purpose of the Study:

• To summarize clinical anesthesia experiences in patients undergoing robotic laparoscopic nephrectomy.
• To analyze anesthesia parameters and their impact on physiological status.

Main Methods:

• Retrospective analysis of anesthesia data from 20 patients.
• Data collected included anesthesia time, operation time, and CO2 pneumoperitoneum duration.
• Recorded physiological parameters: PaCO2, PETCO2, pH, and peak airway pressure.

Main Results:

• Anesthesia and operation times were (220±14) min and (187±11) min, respectively.
• CO2 pneumoperitoneum duration averaged (180±13) min.
• Significant increases in PaCO2, PETCO2, and peak airway pressure were observed post-pneumoperitoneum.
• A significant decrease in pH was noted 2.5 hours post-operation.

Conclusions:

• Hemodynamics remained stable throughout the procedure.
• Prolonged CO2 pneumoperitoneum is a key factor in robotic laparoscopic nephrectomy.
• Increased airway resistance and acid-base disturbances are significant anesthesia considerations.
