Abstract

Spinal anesthesia is a common and secure technique used in many lower abdomen procedures. Yet, it may change how the body regulates its temperature, and 57% of shivering attacks during spinal anesthesia have been documented. Aims and objectives: To evaluate the effectiveness of warm IV fluid and tramadol premedication for prevention of post-spinal shivering in below umbilical surgeries. Materials and Methods: One hundred and twenty patients (age 20-60 years and American Society of Anesthesiology Class I and II) undergoing infra umbilical surgeries under spinal anesthesia were studied in a prospective randomized clinical trial at the Department of Anaesthesia, Gandhi Medical College, Bhopal, from June 2022 to Jan 2023 after dividing them in to group Group IV (n=60, received warm IV fluid over 10 min after administration of spinal anesthesia and Group T (n=60, received an injection of tramadol 50 mg IV in 100 ml NS over 10 min after spinal anesthesia). Shivering was graded as : Grade 0: No shivering, Grade 1: One or more of the following: Piloerection, peripheral vasoconstriction, peripheral cyanosis with, but without visible muscle activity, Grade 2: Visible muscle activity confined to one muscle group, Grade 3: Visible muscle activity in more than one muscle group, Grade 4: Gross muscle activity involving the upper part of the body. Results: No significant difference was observed between the two groups in terms of age, sex, weight, height, body mass index (BMI), ASA status, Mallampati score, and duration of surgery. Incidence of different grades of shivering between both the intervention was comparable (p>0.05). No significant difference was observed in mean surface temperature between the two groups throughout surgery (p>0.05). However, numerically the surface temperatures showed a progressively increasing trend in both groups. No hallucinations or nausea/vomiting were observed in any of the study groups. Conclusion: Prophylactic administration of warm IV fluid and tramadol (50 mg dose) effectively controls shivering under spinal anesthesia without any side effects
