Volume Versus Pressure Ventilation on Lung Atelectasis

January 14, 2024 updated by: Dalia Saad Abd-El Kader, Kasr El Aini Hospital

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.

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.

Study Overview

Status

Active, not recruiting

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.
Pressure controlled versus Volume controlled ventilation using LMA
Other Names:
  • Lung Ultrasound
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.
Pressure controlled versus Volume controlled ventilation using LMA
Other Names:
  • Lung Ultrasound
