Study of Atelectasis by Electrical Impedance Tomography

NCT05713929 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

Last updated 2023-03-15

No results posted yet for this study

Summary

The goal of this interventional study is to learn about the effects of different positions on the occurrence, regional distribution and reversibility of atelectasis by using a PulmoVista 500 monitor (Dräger. 23542 Lübeck), during general anesthesia with mechanical ventilation.

The main questions it aims to answer are:

* The increase in atelectasis after induction of general anesthesia in supine and Trendelenburg position compared with baseline (spontaneous breathing)
* The eventual possibility of reversal of atelectasis caused by general anesthesia and Trendelenburg position by reverse Trendelenburg position and recruitment manœuvre.

Participants will be adult, autonomous and able to express their will, undergoing elective gynecological or urological surgery in the extended Trendelenburg position.

Conditions

  • Gynecologic Surgical Procedures
  • Urologic Surgical Procedures

Interventions

OTHER

Recruitment maneuver (RM)

performance of a recruitment maneuver of 30 cm H20 for 30 seconds and measurement of electrical impedance

OTHER

Reverse Trend (REV TREND)

Place the patient in the reverse trendelenburg position and measuring the electrical impedance after 5 minutes
