Table II.
Comparison of the first exhaust time and the incidence of adverse reactions after surgery between the two groups.
| Variables | Group A (n=158) | Group B (n=140) | t/χ2 test | P-value |
|---|---|---|---|---|
| First exhaust time (h) | 32.53±5.54 | 37.51±6.46 | 7.10 | <0.001 |
| Adverse reactions incidence (%) | 16 (10.13) | 28 (20) | 5.75 | 0.02 |
| Hypotension | 2 (1.27) | 9 (6.43) | 5.57 | 0.02 |
| Pruritus | 3 (1.90) | 13 (9.29) | 7.08 | <0.001 |
| Hypertension | 8 (5.06) | 17 (12.14) | 4.84 | 0.03 |
| Nausea and vomiting | 2 (1.27) | 8 (5.71) | 4.53 | 0.03 |
| Lethargy | 0 (0.00) | 0 (0.00) |
Independent samples t-test was used to analyze the first exhaust time and Chi-square test was used to compare the incidence of adverse reactions. The first exhaust time and the incidence of adverse reactions in group A were significantly lower than those in group B (P<0.05).
