Efficacy of N-butylscopolamine and sodium dipirone associated to ketoprofen for postoperative pain relief of patients submitted to two different laparoscopic sterilization techniques.

BACKGROUND AND OBJECTIVES Laparoscopic sterilization (LS) is one of the most painful procedures and pain severity varies with the selected technique, being more severe when tubes are occluded with rings. Patients submitted to LS refer PO colic pain and N-butylscopolamine and sodium dipirone, for their anti-spasmodic and analgesic properties, associated to ketoprofen with anti-inflammatory properties, may be the option for pain prevention and relief. This study aimed at evaluating the efficacy of N-butylscopolamine and sodium dipirone associated to ketoprofen to prevent PO pain in patients submitted to LS by two different techniques - diathermy and tubal ring. METHODS Participated in this study 50 patients, physical status ASA I and II, aged 23 to 47 years. Patients were randomly distributed in two groups: G1 - tubal ring; G2 - diathermy. All patients received intravenous N-butylscopolamine (20 mg) and sodium dipirone (2500 mg) and ketoprofen (100 mg) immediately before anesthetic induction. Pain was evaluated by verbal numeric scale varying from 0 to 10, being 0 no pain and 10 the worst possible pain, every 10 minutes in the first PACU hour and 1, 2, 3 and 4 hours after PACU discharge. Pain above 3 was treated with intravenous tramadol (100 mg). Pain was evaluated without knowing the group to which the patient belonged. Student's t, Mann-Whitney and Friedman tests were used for statistical analysis. RESULTS Both groups were similar in age, weight, height and length of surgery and anesthesia. G1 patients had higher pain scores as compared to G2, in all studied moments. Statistically significant values were: 80% of G1 and 16% of G2 patients needed tramadol at some point of the study. CONCLUSIONS N-butylscopolamine and sodium dipirone associated to ketoprofen are a postoperative analgesic alternative when sterilization is performed through diathermy technique.
