Abstract
BACKGROUND:
Post-procedural pain control after uterine artery embolization (UAE) of urethral leiomyomata remains a major problem.
METHODS:
This double-blind, randomized study tested the possibility to obtain a quicker onset of analgesia by using effect-compartment controlled remifentanil patient-controlled analgesia (remifentanil TCI-PCA) than by using i.v. morphine PCA. Both systems were connected to an i.v. catheter. Active drug or matching placebo administration was activated by a single push-button. Pain was assessed using a numerical rating scale (NRS) from 0 to 10.
RESULTS:
NRS values were lower in the remifentanil group (with a possible difference from two to seven points on the scale) during the initial 4 h post-embolization. After the fourth hour, the NRS values were identical between the groups. No major respiratory or haemodynamic side-effect was observed.
CONCLUSIONS:
Remifentanil PCA-TCI with a slow and progressive adapted algorithm without any associated premedication or co-medication is feasible in young healthy women undergoing UAE.
