[Clinical study of preoperative analgesia for liposuction].

OBJECTIVE
To observe the effect of the preoperative analgesia with Oxycodone/Acetaminophen for liposuction.


METHODS
In the double-blind, placebo-controlled clinical trial, 40 patients undergoing the liposuction were randomly assigned into two groups which were received a single oral dose of Oxycodone/Acetaminophen or calcium gluconate respectively before the operation. The degrees of pain were evaluated by visual analogue scale (VAS) at the beginning and the end of the operation. Adverse effects and the overall satisfaction on analgesic therapy were assessed when operation finished.


RESULTS
The VAS scores of the experimental group were significantly lower than the control group at the beginning and the end of operation (P < 0.05). There were no significant differences between the two groups in side effects (P > 0.05).


CONCLUSIONS
Oxycodone/Acetaminophen could produce preemptive effect. Preoperative oral administration of Oxycodone/ Acetaminophen may provide patients with good analgesia in plastic and cosmetic operation.
