The Effect of Different Doses of Ketamine on Reducing Shivering after Eelective Cesarean Section
نویسندگان
چکیده
Introduction: Shivering is a protective reaction. It increases the production of body temperature by muscular contraction. Post-surgery shivering is one of the prevalent side effects of anesthesia. This is usually accompanied with other problems such as oxygen consumption increase, intracranialpressureincrease, and other complications. Hence, this study compared the effect of various doses of ketamine on reducing selective post-cesarean section shivering. Materials and Methods: It was a double-blinded, randomized clinical trial. Thirty pregnant women undergoing selective cesarean section under spinal anesthesia at Motahari Hospital, Jahrom participated in this study. They received ketamine (0.3mg/kg and 0.15mg/kg) in two groups of 15. Data was analyzed by T-test, Mann-Whitney test, and Chi square using SPSS16. The level of significance was considered below 0.05 (P<0.05). Results: Patients’ mean age was 27.18 4.38. Mean operation time was 43 16min in ketamine 0.15mg/kg and 40.67 7min in ketamine 0.3mg/kg. No significant difference was observed in this respect. Regarding shivering intensity, most patients had no shivering. The prevalence of ketamine 0.3mg/kg and 0.15mg/kg shivering intensity was not significant in recovery in 5min, 10min, 15min, 30minm and 45min (P-value>0.05). Conclusion: Ketamine 0.3mg/kg is more effective in controlling shivering and other post-surgery side effects as compared to ketamine 0.15mg/kg.

Background &Aims: Acute postoperative pain control after the cesarean section is important due to the importance of the primary contact between the mother and the infant. Two main groups of opioid and non-opioid analgesics are known for controlling pain after cesarean section. The use of opioids in a dose-dependent manner is accompanied by adverse maternal and neonatal complications. Therefore,...

Background Shivering is a frequent and undesirable complication of spinal anesthesia. It is a physiologic response to increase the body core temperature in an attempt to raise metabolic heat production. However, shivering may trigger myocardial ischemia; increase intraocular and intracranial pressures, increase wound pain, delay wound healing and interfere with pulse rate, blood pressure and el...
