Brief summary
The purpose of this study to compare the efficacy of intravenous or intrathecal dexmedetomidine on the incidence of shivering on patients who scheduled spinal anesthesia for elective surgery.
Detailed description
The design of the study includes three study groups done in random order. The groups are as follows: 1) Control group received 15 mg levobupivacaine intrathecally and intravenous 0.9% sodium chloride; 2) Intravenous group received 15 mg levobupivacaine intrathecally and intravenous dexmedetomidine (1mcg/kg/10min, 0.5mcg/kg/h infusion) ; 3) Intrathecal group received 15 mg levobupivacaine + 3 mcg dexmedetomidine intrathecally and intravenous 0.9% sodium chloride. Throughout the study period,shivering scores, tympanic temperature were recorded, heart rate were measured continuously using an electrocardiogram; blood pressure was determined oscillometrically at 5 min intervals at the ankle. In case heart rate decreased by more than 30% of the baseline atropin received and blood pressure decreased 30% of the baseline effedrin received. Side effects (bradycardia, hypotension, hypothermia, nausea and vomiting etc ) were recorded peroperatively in the operating room and postanesthetic care unit.
Interventions
Intrathecal 3ml (15 mg)
Intrathecal 3 microgram (diluted 1/10, 0.3 ml)
Intravenous 1ml/kg/10 minutes and than 0.5 ml/kg/hour infusion in the control and intrathecal groups, intrathecal 0.3 ml in the control and intravenous groups.
