Pressure Support Ventilation During Laparoscopic and Abdominal Robotic Surgery.

April 25, 2023 updated by: Valerii Subbotin, Moscow Clinical Scientific Center
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.

Study Overview

Detailed 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.

The QoR-40 incorporates five dimensions of health: patient support, comfort, emotions, physical independence, and pain; each item is graded on a five-point Likert scale.

QoR-40 scores range from 40 (extremely poor quality of recovery) to 200 (excellent quality of recovery).
