The concept of preemptive analgesia, albeit long-standing, has reemerged. Consequently, recent research has focused on testing a variety of drugs preoperatively to prevent the occurrence of postoperative pain, a major factor of morbidity. Amitriptyline is a tricyclic antidepressant used to treat chronic pain. Because amitriptyline acts on pain transmission pathways, it could theoretically be used as an agent for the prevention of postoperative pain. This study evaluated the effectiveness of amitriptyline in preventing pain in patients submitted to hysterectomy, the most commonly performed gynecological surgery. A randomized, double-blind clinical trial was conducted with 145 patients, 72 of these receiving amitriptyline and 73 placebo. All patients were evaluated at 6, 12, 24 and 48 hours after surgery using a visual analog scale (VAS) for pain and algometry to determine the pressure-pain threshold. Statistical analysis was conducted using the chi-square test of association, Student's t-test, and the Mann-Whitney test, with Fisher's exact test being used whenever appropriate. No statistically signicant difference was found between the two groups with respect to pain at any of the time points evaluated, leading to the conclusion that at a dose of 25 mg, amitriptyline is ineffective in preventing postoperative pain in patients submitted to abdominal hysterectomy

Background & Objectives: Gabapentin has been used successfully as a non-opioid analgesic adjuvant for postoperative pain management. We hypothesized that the preoperative use of gabapentin prolonged the analgesic effect of epidural morphine without an increase in adverse effects of morphine. Materials & Methods: In a randomized, double blind study sixty ASA PS I and II patients undergoing abdominal hysterectomy were assigned to receive either placebo or gabapentin 1200mg 1 hour before surgery. Postoperatively, 0.125% bupivacaine with morphine 50 µg per kg body weight was used for epidural analgesia. Vital parameters, time to the first request for analgesic, visual analogue scale scoring for pain at rest and during movement, 24-hour morphine consumption, and side effects were studied.Results: The patients were comparable with respect to age, weight, ASA PS, baseline hemodynamic parameters and duration of surgery. Gabapentin significantly decreased the duration of analgesia compared to placebo (1078.26 min Vs. 303.5 min; P value <0.0001). The VAS scores at rest and during movement at 1, 2, 4, 8, 12, and 24h were significantly lower in gabapentin group. The total amount of morphine consumption in 24 h postoperatively was significantly lower in gabapentin group (1.93mg Vs. 6.30mg; P value <0.0001). The incidence of nausea and pruritus was significantly lower with gabapentin. Conclusion: Oral gabapentin 1200 mg as a premedication decreases the dose requirement of epidural morphine and postoperative pain after total abdominal hysterectomy. It also decreases the pain scores at rest and during movement significantly.
