Abstract:
Anesthesia can have a significant impact on Peak expiratory flow rate (PEFR) due to several factors that leads to partial airway blockage and restriction air flow making it harder to exhale forcefully. A sample size of 150 study participants was taken, among which 75 subjects were undergone general anesthesia and 75 subjects undergone regional anesthesia. We categorize the participants into 2 groups, where group 1 receives general anesthesia and group 2 receives regional anesthesia. The subjects were selected based on inclusion and exclusion criteria. PEFR (336.02 ± 52.35) and Respiratory rate (16.07 ± 2.42) were found to be drastically reduced in post-operative when compared to pre-operative which was statistically significant (P<0.05). Therefore, it is observed that PEFR is significantly reduced in patients receiving general anesthesia during post-operative period where there is no much change in regional anesthesia.
