Preemptive analgesia in patients undergoing infraumbilical laparotomy under spinal anesthesia: A randomized, double-blind, comparative evaluation of varying doses of oral pregabalin

Aim: To assess the efficiency of preemptive analgesia with Ketoprofen 10 mg 2 hours before procedure per os with spinal anesthesia to decrease postoperative pain and the amount of used analgesics.Methods: Patients of our clinic who meet the following inclusion criteria are included: they must be diagnosed with anorectal disease and planned anorectal procedure. After signing the consent all participants are randomly divided into 2 groups: the first one gets a tablet with 10 mg Ketoprofen, the second one gets a tablet containing starch per os 2 hours before surgery (72 participants per arm). Patients of both arms receive spinal anesthesia and undergo open hemorrhoidectomy. Following the procedure the primary and secondary outcomes are evaluated: opioid administration intake, the pain at rest and during defecation, duration and frequency of other analgesics intake, readmission rate, overall quality of life, time from the procedure to returning to work and the complications rate.Discussion: Multimodality pain management has been shown to improve pain control and decrease opioid intake in patients after anorectal surgery in several studies. Gabapentin can be considered as an alternative approach to pain control as NSAIDs have limitative adverse effects. Systemic admission of ketorolac with local anesthetics also showed significant efficacy in patients undergoing anorectal surgery. We hope to prove the efficacy of multimodal analgesia including preemptive one for patients undergoing anorectal procedure that will help to hold postoperative pain level no more than 3-4 points on VAS with minimal consumption of opioid analgesics.

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: Postoperative nausea and vomiting (PONV) is a common complication associated with the use of anesthesia. Several antiemetics are used to reduce the incidence and severity of PONV. The aim of this study is to investigate the role of dexamethasone and ondansetron to treat PONV in patients undergoing cesarean section (c-section) under spinal anesthesia. Methods: This double-blind clinical trial study was performed on patients who were referred to the operating room of Haji Karim Asali Hospital of Khorramabad for elective cesarean section in 2016-17. Upon meeting the inclusion criteria, patients were allotted into two groups (n=60). Group A received 8mg of dexamethasone and group B received 4mg of ondansetron after spinal anesthesia. The Visual Analog Scale (VAS) questionnaire and Depression-Anxiety-Stress Scale (DASS) questionnaire was used for the analysis. Patients with mild to moderate stress, anxiety, and depression were included in the study. Data were analyzed using SPSS 16 software. Results: There was no difference in the demographic data of the two groups. The mean severity of nausea in group A was significantly higher than in group B. The frequency of vomiting in group A was 20 times higher than group B, which was found to be statistically significant, p = 0.018. Concerning the type of delivery with the frequency of nausea, the results showed that the frequency of nausea in group A was 3.24 times higher than group B, however, this difference was not statistically significant, p = 0.106. Conclusion: Based on the results of this study, ondansetron had a significant effect on the alleviation of postoperative nausea and vomiting, as compared to dexamethasone in c-section surgical candidates.
