简要总结
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.

研究组 & 干预措施
group A
Group A patients received the standard ventilation protocol as follows: volume-controlled ventilation mode, with VT 6 ml/kg of ideal body weight, inspiratory : expiratory ratio 1 : 2, a PEEP of 4 cmH2O, and respiratory rate 10-12 breaths/min that will be adjusted to keep end-tidal carbon dioxide tension (EtCO2) between 35 and 40 mmHg and inspired oxygen fraction of 0.5.
group B
Patients in group B received the standard ventilation protocol with stepwise peep until end of surgery and extubation.
干预措施: stepwise PEEP (Device)
结局指标
主要结局
efficacy of lung ultrasound in optimizing peep
时间窗: intraoperative and early postoperative first 24 hours after recovery from anaesthesia
to evaluate the effect of lung ultrasound in optimizing peep in obese patients undergoing laparoscopic surgeries on the Incidence of intraoperative hypoxia and atlectasis
次要结局
- effect on early postoperative oxygenation(24 hours postoperative)
