Volume Versus Pressure Ventilation on Lung Atelectasis
The Effect of Volume Controlled Versus Pressure Ventilation on Anesthesia Induced Lung Atelectasis in Pediatrics Using Laryngeal Mask Airway (LMA )During Cardiac Catheterization. A Prospective Randomized Study.
Study Overview
Status
Conditions
Intervention / Treatment
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).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Group A pressure control ventilation
Inspiratory pressure was adjusted to achieve an expired tidal volume of 7 ml/Kg, respiratory rate was adjusted to achieve an end ETCO2 at 32-35 mmHg, inspiratory to expiratory ratio at 1:2, PEEP at 4 cm H2O and FiO2 at 0.5 providing that the maximum airway pressure was limited to 25 cmH2O.

Experimental: Group B volume control ventilation
VT adjacent to 7 ml/Kg, respiratory rate was adjusted to achieve an end ETCO2 at 32-35 mmHg and I/E at: 1:2 and PEEP at 4 cm H2O and FiO2 at 0.5.
