Comparative study between intrathecal fentanyl and meperidine to decrease shivering during surgery and cesarean delivery under spinal anesthesia

ABSTRACT

Shivering associated with spinal and epidural anesthesia is common, occurring in up to 56.7% of patients. Shivering is uncomfortable for the patient and interferes with monitoring of electrocardiogram, blood pressure, and oxygen saturation. Those effects are particularly troublesome in the obstetrical population. The aim of this work is to determine whether meperidine [0.2mg/Kg],added to a bupivacaine, decrease the incidence an intensity of shivering during spinal anesthesia. Sixty patients were enrolled in this study, scheduled for non emergent surgery under spinal anesthesia. Patients were randomly devided into three groups group I consisted of 20 cases with spinal anesthesia of hyperbaric bupivacaine [0.5%, 12.5 mg, fentanyl 50 ug], group II consisted of 20 cases with spinal anesthesia meperidine was added [0.2mg/kg], group III consisted of 20 cases with spinal anesthesia, with an equivalent volume of normal saline, in CS Apgar score was recorded at 1, 5 and 10 minutes. The Results Indicated that the incidence of shivering was less in meperidine group there was 5 of 20 versus 15 Of 20 in fentanyl group and 19 of 20 in control group, with P value <0.02. There was no difference between groups as regard Apgar score. It was concluded that intrathecal use of meperidine [0.2mg/kg] reduces the incidence and intensity for shivering associated with interathecal anesthesia
