Effect of TAP Block on Ventilatory Function Following Abdominal Surgery (KTAP)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified October 2012 by Mathieu RAUX, Pierre and Marie Curie University.

Abdominal surgery impairs ventilation. Postoperative pain accounts for this impairment. Regional analgesia is known to reduce pain, thus to limit ventilatory impairment. The investigators hypothesized bilateral continuous transverse abdominal plan block would reduce ventilatory impairment following abdominal surgery.

Condition Intervention Phase
Laparotomy Procedure: Regional analgesia infusion Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Assessment of the Ventilatory Effects of Transverse Abdominal Plan Regional Analgesia Following Abdominal Surgery.
