Overview
Brief Summary
This prospective randomized comparative study, to assess post-operative lung atelectasis by comparing calculated lung score using ultrasound between pediatric patients intubated with LMA (laryngeal mask airway) under volume versus pressure controlled modes of ventilation.
Detailed Description
The initial US scanning will be done prior to the induction of anesthesia. Induction of anesthesia using 4% sevoflurane. Adequate size LMA will be inserted after adequate depth of anesthesia adjusted. Group A (n=25): will receive pressure-controlled ventilation (PCV). Group B (n=25): will receive volume-controlled ventilation (VCV). US scanning and Arterial blood gases at the following: * T1(After maintenance of anesthesia). * T2 (One minute after applying groin bandage and before extubation). * T3 (10 minutes after extubation and resumption of adequate regular breathing). * T4 (30 min post extubation).

Outcomes
Primary Outcomes
Post operative incidence of Lung atelectasis immediate post-removal of LMA.
Time Frame: immediated post removal of LMA
calculate lung score using lung ultrasound
Secondary Outcomes
- Correlation between lung score and PaO2 /FiO2 ratio(From the preoperative period (T0) to 30 minutes post-extubation)
