Preemptive analgesia application in acute appendicitis

BACKGROUND: Preemptive analgesia with infiltration of anesthetics into surgical wounds before the incision has been shown to be effective in various elective surgeries. Although this application can decrease the postoperative pain, it is not known whether it is effective in surgery with acute pain or not. AIMS: In this study, we evaluated whether the preincisional local anesthetic application will decrease the postoperative pain in patients undergoing appendectomy for acute appendicitis. MATERIALS AND METHODS: Forty consecutive patients admitted to the Emergency Department with a tentative diagnosis of acute appendicitis were randomly divided into two groups. In Group 1, 1% prilocaine and 0.25% bupivacaine was injected to the planned incision site cutaneously, subcutaneously, and under the fascia of the external oblique muscle. The patients in Group 2 received the same volume of saline to the same anatomical sites. Initially, 1 mg/kg meperidine was administered intramuscularly to both groups for postoperative analgesia. If needed further, meperidine 0.5 mg/kg was administered intramuscularly. Postoperative pain was assed by visual analog scale during the first 24 hours. The analgesic needed and the doses required were recorded. STATISTICAL ANALYSES: All data were stored using SPSS 11.0 for Windows. Wilcoxon test and two independent samples T-test was used as the non-parametric test. RESULTS AND CONCLUSIONS: No statistically significant difference was found between the two groups' pain score, the number of patients who needed analgesic, and the amount and the number of doses administered. In conclusion, we think that preincisional local anesthetic infiltration does not help to decrease the need for postoperative analgesic use in patients with acute pain, and this may be related with previous central sensitization

The Efficiency and Duration of the Analgesic Effects of Musical Therapy on Postoperative Pain

OBJECTIVES: The aim of this study was first to find out the effect of music therapy on postoperative analgesia and second to determine the duration of its effect. METHODS: Seventy patients who were undergoing elective cesarean delivery were enrolled. The patients were randomly allocated into two groups as follows: In Group 1, patients listened to music through a headphone for one hour after surgery, while in Group 2, patients did not listen to any music during the same period. In the postanesthesia care unit, patients were connected to a Patient Controlled Analgesia (PCA) device. The PCA device (tramadol 3 mg/ml) was set to deliver a bolus of 20 mg, with a lockout interval of 15 min and 4-hour maximal dose of 150 mg. Postoperative pain was assessed with a visual analog scale (VAS) and consumption of tramadol was recorded at 4, 8, 12, 16, 20 and 24 hours. RESULTS: There was a significant decrease in Group 1 with respect to PCA delivery frequency at the 4th hour postoperatively (p\u3c0.05). Concerning the postoperative tramadol consumption, values measured at the 4th hour were significantly lower in Group 1 (p\u3c0.05). The total amount of tramadol consumption and additional analgesic use in the postoperative 24 hours were again lower in Group 1 when compared with Group 2 (p\u3c0.05). All VAS values were lower in Group 1 when compared with Group 2 (p\u3c0.05). CONCLUSION: We suggest that music therapy given after surgery decreases postoperative pain in the first 24 hours and the analgesic consumption during the first four hours

Effects of the menstrual cycle on injection pain due to rocuronium

WOS: 000325732900009PubMed: 23965205Study Objective: To investigate the effect of the menstrual cycle on rocuronium injection pain. Design: Prospective, randomized, double-blinded study. Setting: Academic medical center. Patients: 80 ASA physical status 1 and 2 women scheduled for elective surgery with general anesthesia. Measurements: Patients were divided into two groups according to their time in the menstrual cycle. Forty patients at days 8 to 12 of the menstrual cycle were considered to be at the follicular phase (Group F), and 40 patients at days 20 to 24 of the menstrual cycle were considered to be at the luteal phase (Group L).Withdrawal movements were recorded. Main Results: Overall frequency of withdrawal movements was significantly higher in Group L than Group F (P < 0.001). The mean withdrawal movement score was 1.77 +/- 0.76 in Group L and 0.52 +/- 0.67 in Group F. Conclusion: Menstrual cycle phases affect the severity of rocuronium injection pain. Women exhibit greater pain sensitivity from rocuronium injection in the luteal phase than the follicular phase. (c) 2013 Elsevier Inc. All rights reserved
