Conditions

Laparotomy

Brief summary

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.
