Abstract
Introduction: Pain relief has been received the highest level of medical attempts continuously but still many patients suffer from it. Narcotics' side-effects have led investigators to apply other techniques for controling acute postoperative pain to reduce narcotics requirements. Recently, some concepts have been presented implying that Metoclopramide does have analgesic effects and this led us to conduct the present study in order to determine Metoclopramide's effect on alleviating pain after cesarean section. Materials and Methods: In this clinical trial, 80 patients who were candidates of elective cesarean section were studied in two groups. 10 minutes before the cesarean section's ending time, the control group was given 25 mg Pethidine accompanied by 10 mg Metoclopramide and control group 25 mg Pethidine and distilled water. Then when patients were conscious after cesarean section, for a period of 6 hours received after-care for their vital signs and side-effects of prescribed drugs. Their pain score (VAS) and nausea rate was measured and if necessary, Pethidine was injected with certain dose. Injection time for first dose of Pethidine and its required amount were recorded in a checklist within first 6 hours after cesarean section. Data was analyzed using ANOVA and T tests. Results: Prescription of Metoclopramide inhaunced analgesic effect of narcotics and a meaningful decrease was found in pain score (p=0.002) and nausea rate (p<0.005). Injection time for the first dose of Pethidine was also prolonged in the group who received Metoclopramide compared to control group (p=0.019) and an obvious decrease was occurred in received Pethidine's amount within the first hours after cesarean section (p<0.005). Drugs side-effects were not found in patients. Conclusion: The results indicate that use of Metoclopramide accompanied by Pethidine in ending time of cesarean section, does have considerable effects in controlling acute pain after surgery and increasing analgesic effect of narcotic drugs. Therefore, use of Metoclopramide as a proper supplement drug with low side-effects is recommended.

Abstract
Background: Postoperative shivering is a common problem with multiple complications. This study was compared effect of low doses of Ketamine with Pethidine for controlling postoperative shivering. Methods and Materials: This clinical trial was done on 189 elective cesarean section with ASA class I or II who had postoperative shivering. Patients with grade 2 or higher were divided in three groups and were injected 0.3mg/kg Ketamine and 0.5mg/kg Pethidine intravenously. In 5th and 10th minutes after injection, they were investigated for shivering intensity. Results: After 5 minute of injection drugs rate and intensity of shivering in Pethedine group was less than ketamine group. Ketamine with 0.5 mg/kg was more effective than 0.3mg/kg dose of it and Ketamine(p=0.041). In group with 0.5mg/kg dose of Ketamine, rate and intensity of postoperative shivering was more reduce than group with 0.3mg/kg of it in recovery(p=0/007). In Pethedine group rate and intersity of shivering was more reduce then 0.5mg/kg dose of Ketamine(p<0/001). This demonstrated that Pethedine is more effective than Ketamine. Conclusion: Although 0.5mg/kg dose of Ketamine has considerable effect on control of shivering but Pethedine is still a better choice for this side effect.
