Intra-ocular Pressure and Ventilation

NCT02731404 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 26

No results posted yet for this study

Summary

Background: Positive pressure pneumoperitoneum (PP) may involve adverse pathophysiological changes, including increased intra-thoracic and ocular pressure, when combined with standard ventilation. High frequency jet ventilation (HFJV) was reported to reduce the adverse cardiovascular effects during laparoscopic cholecystectomy.

Aim: To study the effects of HFJV on intra-ocular pressure changes (reflecting intra-cranial pressure) during laparoscopic surgery under PP.

Conditions

  • Pneumoperitoneum

Interventions

PROCEDURE

HFJV ventilation

The investigators used the Perkins tonometer for monitoring intra-ocular pressure. Evaluation of intra-ocular pressure was done before induction of anesthesia, end of induction, during surgery and at the end of surgery.

PROCEDURE

IPPV ventilation

The investigators used the Perkins tonometer for monitoring intra-ocular pressure. Evaluation of intra-ocular pressure was done before induction of anesthesia, end of induction, during surgery and at the end of surgery.
