Overview
Brief Summary
the aim of this prospective randomized blinded clinical study will be to assess the ultrasound evaluation of different preventive measures of post operative lung atelectasis in abdominal surgeries; these measures include ventilation and fluid measures
Detailed Description
ultrasound evaluation for application of different preventive measures of post operative lung atelectasis, including positive end-expiratory pressure, lung recruitment maneuvers, and restrictive fluid management.

Outcomes
Primary Outcomes
Lung ultrasound assessment of postoperative pulmonary atelectasis at the end of surgery
Time Frame: at the end of surgery before emergence from GA.
Lung ultrasound assessment of postoperative pulmonary atelectasis at the end of surgery. The Lung Ultrasound Score (LUS): the key points based on ultrasound findings: I. 0 points: (N) Normal aeration (presence of lung sliding with A-lines or \<2 separate B-lines). II. 1 point: (B1) Moderate loss of lung aeration (≥3 well-defined B lines). III. 2 points: (B2) Severe loss of lung aeration (coalescing B-lines). IV. 3 points: (C) Complete loss of lung aeration (pulmonary consolidations). Total Score: points will be distributed according to the worst ultrasound pattern observed: N = 0, B1 lines = 1, B2 lines = 2, C = 3. The LUS score ranging between 0 and 36 was calculated as the sum of points.
Secondary Outcomes
- Lung ultrasound assessment(60 minutes after patients arrive to PACU)
- arterial blood gases(15 minutes after patients arrive to PACU)
