Ultrasound Evaluation of Preventive Measures for Postoperative Lung Atelectasis After Surgery

Not Applicable

Recruiting

• Conditions: Pulmonary Atelectasis, Postoperative

• Registration Number: NCT06654778
• Lead Sponsor: Al-Azhar University

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.

Primary Outcome Measures

Name	Time	Method
Lung ultrasound assessment of postoperative pulmonary atelectasis at the end of surgery	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 Outcome Measures

Name	Time	Method
Lung ultrasound assessment	60 minutes after patients arrive to PACU	Lung ultrasound assessment of atelectasis
arterial blood gases	15 minutes after patients arrive to PACU	Pao2, spo2, paco2, pao2/fio2
