High-flow nasal cannula oxygenation in comparison with apnoeic oxygenation during foreign body removal by rigid bronchoscopy

Abstract

Introduction: Main aim is to study efficacy of high low nasal cannula oxygenation in comparison with apnoeic oxygenation during foreign body removal by rapid bronchoscopy. Material & Methods: A prospective, blinded, randomized, controlled trial was conducted on subjects planned foreign body removal by a rigid bronchoscope. Patients under Inclusion criteria were selected for the study. Were male and female patients aged between 20 and 40 years. Results: Study was carried out in 100 subjects and divided into two subgroups 50 patients in group A HFNC and 50 patients in group B Apnoeic Oxygenation. The study was carried out in 20 to 40 years. Majority of the patients were in the age group of 31 – 40 years there were 56 % followed by 41 – 50 years there were 31% and 20 – 30 years 13%. Total male were 70 patients and 30 females (p 0.428). There were 36 patients having branchospasm (p 0.512). Study was also carried for monitoring invasive ventilation in two subgroups but in subgroup A among 50 patients 08 patients having invasive ventilation and in group B 14 patient’s (p > 0.520) which is statically in significant.
