PULMONARY CHANGES DURING UPPER GASTROINTESTINAL ENDOSCOPY

Objective: To evaluate the pulmonary changes in patients underwent gastrointestinal endoscopy at tertiary care hospital Patients and Methods: The patients underwent upper GI endoscopy were explored, enrolled and recruited in this six months cross sectional study after taking informed consent. The respiratory system examination was performed while before, during and after the SPO2 monitoring was done simultaneously by pulse oximetry. The data saved on pre-designed proforma and analyzed in SPSS 16 while the mean ±SD, frequencies and percentages was calculated. Results: The mean age ± SD for whole population was 53.98±7.96. Of fifty the de-saturation was identified in 22 patients of which mild oxygen desaturation (SPO2 < 95%) in 8 (36.3%) of the patients, moderate oxygen desaturation (SPO2 90- 95%) in 9 (40.9%) and severe desaturation (SPO2 <90%) in 5 (22.7%) patients. The mean ±SD for SPO2 % in male and female population before the procedure was 98.62± 1.21 and 98.85± 1.56 while during the procedure it was 93.42± 1.85 and 93.81± 2.95 whereas after the procedure was 96.98± 2.52 and 98.21± 1.21 respectively. Conclusion: The present revealed transient hypoxic events during endoscopy and did not lead to significant pathology. Thus in elderly subjects and the individuals with co-morbid conditions or in the patients with pre existing lung diseases oxygen saturation should be monitored during the endoscopic procedure.
