Comparison of postoperative adverse reactions among three groups
| Control (n = 30) | PN‐Dex (n = 31) | i.v.‐Dex (n = 30) | p value | |||
|---|---|---|---|---|---|---|
| p a | p b | p c | ||||
| PONV (%) | 10 (33.3) | 2 (6.5)* | 1 (3.3) # | 0.01 | <0.01 | 0.99 |
| Respiratory depression (%) | 1 (3.3) | 0 (0) | 2 (6.7) | 0.49 | >0.99 | 0.24 |
| Urinary retention (%) | 0 (0) | 1 (3.2) | 2 (6.7) | >0.99 | 0.49 | 0.61 |
| Persistent nerve palsy (%) | 0 (0) | 0 (0) | 0 (0) | >0.99 | >0.99 | >0.99 |
Note: p a, PN‐Dex group vs. control group; p b, i.v.‐Dex group vs. control group; p c, PN‐Dex group vs. i.v.‐Dex group.
Abbreviations: Dex, dexamethasone; PN, perineural; PONV, postoperative nausea and vomiting.
*
The comparison between PN‐Dex group and control group was statistically significant (p < 0.05).
#
The comparison between the i.v.‐Dex group and the control group was statistically significant. (p < 0.05).
