تأثير تقنية التطويع الرئوي في تحسين الأكسجة الشريانية و زمن التهوية الاصطناعية بعد جراحة القلب المفتوح

Abstract EN

Background & Objective: It's well known that general anesthesia causes lung atelectasis in a different degrees, begins at the induction of anesthesia and persists several hours after the end of the surgery, and in open cardiac surgery there are additional causes of atelectasis, some researchers have shown that Recruitment Maneuver can prevented atelectasis, improved oxygenation post-op and attenuated pulmonary complications after surgery, we aimed in this research to find the benefits of Recruitment Maneuver in coronary artery bypass grafting CABG Methods & Materials: 80 patients undergoing coronary artery bypass surgery were randomized into two groups :RM group Recruitment Maneuver applied by pressure 40 cm water for 10 seconds in the end of surgery and CNT group, PaO2/PaO2 and mechanical ventilation time were evaluated and compared between the groups.

Results: In the first 6 hours after surgery, the oxygenation was better in RM group patients compared to that in the CNT patients (P=0.01), without a significant difference regarding the duration of mechanical ventilation.

Conclusion: Recruitment Maneuver provided better oxygenation in the first 6 hours after open cardiac surgery without improving extubation time.
