EFFECT OF WOUND INFILTRATION WITH 0.25% BUPIVACAIN VIA CATHETER ON POST OPERATIVE PAIN AFTER CESAREAN SECTION
Abstract
Introduction: The control of postoperative pain after cesarean section is one of the problems which is always in physicians mind. Unsuccessfulness in the pain management is not only psychologically unpleasant but also in causes post operative complications. Also due to the need of early ambulation of these patients, enough analgesia is needed post operatively. The most common pain relieving method postoperatively is the use of systemic narcotics and/or NSAlD's, which have their own side effects. In the field of postoperative analgesia many researches by using one dose infiltration of Bupivacaine in operation field is done. But as far as there is contra version in the effectiveness of this method. Methods: we decided to research the effect of repeated infiltration of Bupivacaine in incisional side via catheter in cesarean section from 77/7/1 till 77/12/31 in Isfahan Beheshti Hospital. And the analgesic effect of Bupivacaine infiltration on horizontal incision of cesarean section is studied, and compared with the control group which give a intramuscular declofenac as an analgesic. The amount of the severity of pain is measured via VAS method every 6 hours post operatively, and the consumption amount of narcotics and the average percentage of vital signs variations were measured and recorded. The analysis of the data was done by using Hest and Chi-square test. Results: the pain severity in 12, 18 & 24 hours post operatively was lower in studied group than control group. These differences were statistically meaningful. The mean percentage of the changes of systolic blood pressure for 24 hours in comparison with its base was also lower in studied group, this difference was also statistically meaningful, too. Discussion: The results show that the local infiltration of Bupivacain is effective in reducing post operative pain and the analgesic requirement. So using this method can be a suitable replacement of systemic analgesic drugs with less side effects.
