Abstract

|
Pain control methods after closed thoracostomy in spontaneous pneumothorax patients were used by analgesics, physical therapy, intercostal nerve block but effectiveness have not been proved due to various side effect and uncertified therapic effect. In this study, transcutaneous electrical nerve stimulation(TENS) was applied to pain control and it´s effectiveness was observed from immediate closed thoracostomy to post-operative 3 days.
Forty-five closed thoracostomy patients was classified into 3 groups, which are TENS group(n=15), placebo group(n=15) and control group(n=15). The TENS group was treated with TENS unit, the placebo group was treated using the unit without electrical connection, and the control group received analgesic alone. Same analgesic(demerol) intramuscular injection was used in three groups as pain control. Among the 3 groups, there were no statistical significant difference in age, body weight, operation time, lidocaine amounts and vital signs. However pain intensity by visual analogue scale and analgesic requirements were decreased in TENS group as compared with others(P<0.05).
Finally, pain control by TENS after closed thoracostomy was proved to effective pain control method therefore analgesic requirements was decreased.
