Figure 2: Mean peak expiratory flow rate (PEFR) at different time interval during the 24-h study period. Bars indicate standard error of mean (SEM). At 8, 12 and 24 hrs postoperatively significant reduction in PEFR was observed compared to baseline only in IVPCA group. *indicate P < 0.05 from the baseline (pair t test), within group comparisons
