Background and Objective: Shivering is one of the common problems during spinal anesthesia and may lead to numerous complications. Shivering may reduce oxygen supply to the pregnant mother or increase the amount of oxygen consumption, which leads to significant decrease in arterial oxygen and dangerous side effects in the fetus.
Materials and Methods: In an interventional double blinded clinical trial, a total of 100 ASA I and II pregnant women were enrolled. Patients were randomly assigned into two groups. Inter-vention group or G group (n=50) received 3 mg intravenous granisetron immediately after spinal anesthesia. Control group (n=50) received 3 ml intravenous normal saline immediately after spinal anesthesia. Then, patients were categorized in 5 degrees from zero to 4 scores in terms of shivering rate during and after surgery and compared between two groups.
Results: there were no significant differences between intervention and control groups in terms of demographic data (age, weight, duration of anesthesia, duration of surgery and central temper-ature (P>0.05). There was a significant difference between intervention and control groups in terms of shivering frequency (P=0.001).
Discussion and Conclusion: The results showed that intravenous granisetron decreased shiver-ing in parturients undergoing caesarean section with spinal anesthesia.
