Clinical Trial Summary

This study is a single-center, blind, prospective, randomized, controlled trial of pressure support ventilation (PSVpro) versus pressure control ventilation - volume guaranteed (PCV - VG) during laparoscopic and robotic abdominal surgery.

Description:

The objective of the study to evaluate the possibility and feasibility of using PSVpro during anesthesia during long-term laparoscopic and robot-assisted abdominal operations at different levels of neuromuscular block.

Intervention: We plan to include 100 patients who will undergo elective long (more 2 hours) laparoscopic or abdominal robotic surgery. All patients will be randomly assigned in two groups in ratio 1:1. 1 group- deep neuromuscular block and mandatory ventilation; 2 group- partial neuromuscular block and pressure support ventilation.

Expected Results. PSV may reduce the systemic inflammatory response compared to the mandatory ventilation during laparoscopic and abdominal robotic surgery.
