The Efficacy Of Ginger And Doxedetomidine In Reducing Postoperative Nausea And Vomiting In Patients Undergoing Abdominal Hysterectomy.

BACKGROUND: Nausea and vomiting are the most common complaints of patients after any general anesthesia, which are often accompanied by postoperative pain. Previous studies showed that ginger and dexmedmoidine can reduce postoperative nausea and vomiting. Therefore, the effectiveness of ginger was compared with dexmedmoidine for prevention of postoperative nausea and vomiting. METHODS: This randomized clinical trial study was performed on 92 patients who had abdominal hysterectomy in a double-blind evaluation. In this study, 92 patients were randomly divided into two equal groups of dexmedmotidine and ginger. In the ginger group, 1 gr of ginger was given orally before and after the anesthesia and in the second group, 25 mg of dexmedmotidine was slowly injected before surgery. Finally, after the operation, the questionnaire was completed for patients and the data obtained from the questionnaires were analyzed by SPSS19 software. RESULTS: There was a significant difference between the two groups of dexmodetomidine and ginger in terms of scorpion vomiting in recovery and 2 hours after operation. Vomiting scores were significantly lower in the ginger group than dexmodetomidine group (P = .02 and P = .03). However, no significant difference was defined between the two groups 4 hours after operation, and the scoring was reported to be zero in both groups. Moreover, a decreased level of nausea was observed in the ginger group as compared to the of dexmedetomidine group. CONCLUSION: Both dexmedmotidine and ginger are effective in reducing postoperative nausea and vomiting. But the effect of ginger is greater than that of dexmodetomidine.

Comparison of intradermal Dexmedmotidine and subcutaneous Ketamine for post-surgical pain management in patients with abdominal hysterectomy.

Hysterectomy after cesarean section is the second most commonly used surgery for women in the United States. One of the most common problem after hysterectomy is pain. We decided to compare the effects of dexmedmotidine or ketamine on pain in patients by a double blind randomized clinical trial on 126 female candidates for abdominal hysterectomy in three groups of 42 persons referred to Taleghani hospital in Arak. For the first group, 50 micrograms of intradermal dexmedmotidine were injected, while in the second group, patients were injected with 100 mg of subcutaneous ketamine and the third group received 5 cc normal saline. Data were next analyzed by SPSS version 19. The mean age and body mass index of the patients were not significantly different in the three groups. The mean scores of pain during recovery of patients in ketamine, dexmedmotidine and placebo groups were 4.2±0.77, 2.6±0.89 and 1.3±0.87, respectively (p = 0.001). Scores of pain in patients at 4 and 8 hours after surgery showed also significant differences. In conclusion, ketamine and dexmedmotidine significantly reduce the severity of pain, but ketamine has a lower effect.

Comparison of Dexmedetomidine and Fentanyl as an Adjuvant to Lidocaine 5% for Spinal Anesthesia in Women Candidate for Elective Caesarean.

AIM: This study aimed to compare the effect of Dexmedetomidine and fentanyl as an adjuvant to lidocaine 5% in spinal anaesthesia to increase post-operative analgesia among women candidates for elective caesarean. METHODS: Eighty-four pregnant women candidates for caesarian were randomly divided into fentanyl and Dexmedetomidine groups. In the first group, 25 µg fentanyl was added to lidocaine 5% while in the second group, 0.5 µg per kilogram Dexmedetomidine was added to lidocaine 5%. After the operation, a pain score of the patients in recovery and within 4, 12 and 24 hours after the operation, the average length of analgesia and the average amount of the analgesics taken within 24 hours and after the operation were recorded. RESULTS: The average length of postoperative anaesthesia and the average amount of the drug taken within the first 24 hours after the operation in fentanyl group was more than the Dexmedetomidine group (P = 0.01). Shivering in Dexmedetomidine group was more common than what was observed in the fentanyl group (P = 0.001). Higher rates of nausea-vomiting were observed in the fentanyl group (P = 0.001). CONCLUSIONS: Fentanyl results in a longer period of postoperative analgesia and less consumption of drugs after the operation. Fentanyl is recommended in caesarian.

Investigation of Ondansetron, Haloperidol, and Dexmedetomidine Efficacy for Prevention of Postoperative Nausea and Vomiting In Patients with Abdominal Hysterectomy.

AIM: This study was aimed to compare the effects of ondansetron, haloperidol, and dexmedetomidine for reducing postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy. METHODS: This randomised clinical trial study was performed on p.patients who were candidates for abdominal hysterectomy referring to Taleghani hospital in Arak. In this study, 114 patients with abdominal hysterectomy were randomly assigned to three groups (ondansetron, haloperidol, and dexmedetomidine) using the cubull randomisation method. RESULTS: The results revealed a significant difference between the three groups of ondansetron, haloperidol and dexmedetomidine in terms of scorpion vomiting in recovery, 2 and 4 hours after surgery, and vomiting score was significantly lower in the ondansetron group compared with the other two groups (P = 0.04; P = 0.02; P = 0.001). There was a significant difference between the three groups of e ondansetron, haloperidol and dexmedetomidine regarding the mean dose of metoclopramide in mg for 24 hours after surgery. Therefore, the dosage of dexmedetomidine in the ondansetron group was less than the other two groups (P = 0.001). CONCLUSION: these three drugs are effective in reducing PONV in patients undergoing a hysterectomy. However, the effect of ondansetron was found to be more than the other two drugs in reducing PONV.
