Brief Summary

Lung ultrasonography is an easy-to-use, portable, non-invasive, visual, and non-radiative technique that has been widely used in clinical monitoring and diagnosis. Many studies have demonstrated that pulmonary ultrasonography can evaluate the degree of aeration loss and diagnose atelectasis accurately by using a validated semiquantitative score in the perioperative period, and lung ultrasonic imaging can be conducive to confirming the effects of lung recruitment manoeuvres. This clinical trial suggested that the use of ultrasound-guided recruitment maneuver in morbidly obese patients scheduled for laparoscopic bariatric surgery can improve the lung aeration, decrease the incidence of basal lung atelectasis, decrease the incidence of intraoperative\& postoperative oxygen desaturation, and reduce the incidence of post operative pulmonary complications. The aim of this prospective randomized clinical study is to compare the conventional recruitment manoeuvre and ultrasound-guided recruitment manoeuvre in morbidly obese patients scheduled for laparoscopic bariatric surgery.

Outcome Measures

Primary Outcomes (1)

  • the change of Lung Ultrasound Score

    Assessment of the changes in the lung ultrasound score

    2 hours

Secondary Outcomes (2)

  • The incidence of atelectasis

    2 hours

  • The incidence of intra-operative desaturation

    3 hours

Study Arms (2)

Conventional group (group C)

EXPERIMENTAL

Patients will be shifted to 100% Oxygen then; the recruitment maneuver will be performed by manual inflation with a pressure of 30 cmH2O for 30 seconds.

Device: Lung Recruitment Conventional

Ultrasound-guided group (group US)

EXPERIMENTAL

Patients will be shifted to 100% Oxygen then; the recruitment maneuver will be performed under the direct real-time guidance of ultrasound if atelectasis (defined as LUS of ≥ 2 for any of the 12 regions) is present. This will be done by manual inflation with a pressure of 10 cmH2O for 10 seconds, increased 10 cmH2O every 10 seconds until no collapsed areas are visible on the ultrasound, the maximum airway pressure will be limited to 40 cmH2O. This could be repeated if needed.
