Abstract
Background: Analyzed report of Arterial Blood Gas is indicated in almost all patients admitted through emergency department (ED). ABG measurements are widely used in hospitals now a day. Its use is particularly confined in ICU as monitor due to lack of test of accuracy and availability of simple method of analysis, Management if started after correlating the clinical diagnosis with that of ABG diagnosis, mortality is reduced and discharge is improved.
Method: Prospective randomized controlled trial had been done over 136 patients of ED. Allocation ratio was 1:1. One group was managed in the background of analyzed ABG measurements and the control group was managed according to the traditional method. The ABG measurements were analyzed according to “rkdas Indian 2017 method of ABG interpretation”. The primary and secondary outcomes were assessed statistically. Patients and outcome access were blinded.
Result: The percentage of death in the study group is significantly less than the control group (p-value 0.22) with 95% confidence interval (3.08 – 17.52). The percentage of discharge is significantly more in study group than control group (p-value 0.036) with 95% confidence interval (50.25 -73.35).
Conclusion: Management in the background of interpreted ABG decreases the mortality and improves the number of discharge.
