aim: to evaluate the efficacy of locally applied bupivacaine in decreasing postoperative pain in patients undergoing minilaparotomybilateral partial salpingectomy. methods: a total of 100 women scheduled for surgical sterilization were randomized to either an intervention group that received 2.5mg of bupivacaine in the mesosalpinx and 2.5 mg in the stump of each fallopian tube or a control group that received no intervention. postoperative pain was measured at one and four hours using the visual analogue scale (vas, 0-10 cm). in addition, these scores determined the necessity and quantity of postoperative analgesia.to compare means we used student t-test and all tests were performed using stata statistical software 10.0.a critical point of 0.05 (p≤ 0.05) was defined as statistically significant. results: scores on the visual analogue scale (vas cm) were 4.7 at one hour and 2.6 at four hours in the intervention group, compared to 5.3 at one hour and 2.6 at four hours in the control group (p>0.05). the application of bupivacaine significantly reduced requests by participants for a second dose of analgesics after the first hour of surgery (p<0.03). the control group showed an increased use of opiates (n=8) in comparison to the bupivacaine intervention group (n=1).the application of bupivacaine to the fallopian tube stumps and mesosalpinx at the time of minilaparotomy surgical sterilization does not produce differences in the postoperative pain management as measured by the visual analogue scale at one and four hours post-surgery. conclusion: the application of bupivacaine is effective in reducing the need for analgesics one hour post-surgery and reduces the use of opioids.
