Summary

Lung ultrasound imaging is a promising non-invasive, non-radiant, portable and easy to use tool that as yet to be studied in the intraoperative setting.

in our current study, we are trying to reach the optimum PEEP in laparoscopic bariatric patients to prevent postoperative collapse and atlectasis with simple non-invasive procedure.

Conditions

  • Atelectasis, Postoperative Pulmonary

Interventions

DEVICE

stepwise PEEP

* a PEEP of 4 cmH2O will be used after intubation till 5 minutes after pneumoperitonium, and adjusted in a step wise approach after lung ultrasound by adding 2 cmH2O, repeating ultrasound 5 minutes after every change in peep till no lung collapse is detected by lung ultrasound with a maximal peep of 10 cmH2O, or if hemodynamic instability occurs. * Lung ultrasound examination will be performed at a minimum three times in each patient; the first will be performed 1 min after starting mechanical ventilation of the lungs, 5 minutes after pneumoperitonium, 5 min after every peep increase in stepwise peep group and the last time at the end of the surgery. We define anaesthesia-induced atelectasis to be significant if any region has a consolidation score of ≥ 2.
