Effects of warmed carrier fluid on nefopam injection- induced pain

Statement of the Problem
: Nefopam is a non-opioid, non-steroidal analgesic drug with fewer adverse effects than narcotic
analgesics and nonsteroidal anti-inflammatory drugs, and is widely used for postoperative pain control. Because nefopam
sometimes causes side effects such as nausea, vomiting, somnolence, hyperhidrosis and injection-related pain, manufacturers
are advised to infuse it slowly, over duration of 15 minutes. Nevertheless, pain at the injection site is very common. Therefore,
we investigated the effect of warmed carrier fluid on nefopam injection-induced pain.
Methodology &Theoretical Orientation
: A total of 48 patients were randomly selected and allocated to either a control or a
warming group. Warming was performed by diluting 40 mg of nefopam in 100 ml of normal saline heated to 31-32°C using
two fluid warmers. The control group was administered 40 mg of nefopam dissolved in 100 ml of normal saline stored at room
temperature (21-22°C) through the fluid warmers, but the fluid warmers were not activated.
Findings
: The pain intensity was lower in the warming group than in the control group (P<0.001). The pain severity and
tolerance measurements also showed statistically significant differences between groups (P<0.001). In the analysis of vital signs
before and after the injection, the mean blood pressure after the injection differed significantly between the groups (P=0.005),
but the heart rate did not. The incidence of hypertension also showed a significant difference between groups (P=0.017).
Conclusion & Significance
: Use of warmed carrier fluid for nefopam injection decreased injection-induced pain compared to
mildly cool carrier fluid.
