Abstract

BACKGROUND
Nefopam is used to improve postoperative hypothermia in the field of plastic and aesthetic surgery. However, there is a paucity of data about its adverse hemodynamic effects and safety. We therefore assessed its adverse hemodynamic effects in patients undergoing plastic and aesthetic surgery.
METHODS
We conducted a single-center retrospective study of 148 patients, in whom we measured hemodynamic parameters using sphygmomanometry (systolic blood pressure [SBP], diastolic blood pressure [DBP], arterial blood pressure [ABP], and heart rate [HR]). Moreover, we also assessed myocardial oxygen demand using the rate pressure product (RPP).
RESULTS
The patients included 96 men and 52 women, with a mean age of 34.7±8.5 years. There were no significant differences in SBP, DBP, ABP, HR, or RPP before and after nefopam administration (P>0.05). However, a significant difference was found in the number of the patients with an HR of >100 beats per minute or with an RPP of >12 U before and after nefopam administration (P=0.001).
CONCLUSIONS
Surgeons should consider the possibility of tachycardia and increased blood pressure in the management of postoperative hypothermia in patients with cardiac arrhythmia, ischemic heart disease, or essential hypertension. Nonetheless, further prospective, large-scale, multi-center, randomized, controlled studies are warranted to confirm our results.
