Abstract
Background: Arterial hypoxaemia is the commonest complication, since respiratory depressant drugs are used for premedication, and the airway
is also partially occluded by the bronchoscope. The study is therefore designed to nd out the changes in arterial oxygen tension during FOB along
with effect on central hemodynamics, electrocardiographically.
Objectives:
· To nd out the changes in arterial oxygen tension during FOB.
· To study the effects of beroptic bronchoscopy on central hemodynamics, electrocardiographically.
Methods: 100 patients aged 20 years and above undergoing FOB were evaluated for the arterial oxygen tension and cardiac rhythm changes at
KNCH, Jodhpur.
Results: All patients developed a fall in PaO2 following FOB which was highly signicant but hypoxaemia was noted only in 18 cases. There was a
uniform rise in heart rate in all the patients after FOB which was statistically signicant. There was slight sinus tachycardia in most of the cases
although E.C.G. indicated no major arrhythmias. There was no signicant change in pH level. Mean of SBP and mean of DBP was statistically
signicant.
Conclusion: All patients showed a decline in arterial PaO2 after FOB which was highly signicant. There was slight sinus tachycardia in most of
cases. FOB itself does not endanger the patients with any signicant or serious complications.
