Hyperthermia by hot pack prevents sharp pain and skin symptom at IFN injection intramuscularly

Abstract

Forty-four patients with chronic hepatitis C who took an IFN treatment were included in this study. An injection part was warmed by hot pack before and after intramuscular injection. Hyperthermia by hot pack decreased the cases that appealed for sharp pain from 63% to 32% (p<0.01), and was effective for prevention of sharp pain and of a skin symptom. This result suggests that hyperthermia by hot pack is effective means for patients forced to intramuscular injection for a long term.
