Abstract

Objectives: To evaluate the shivering preventive effect and other unwanted effects of ketamine 0.2 mg/kg intravenous injection after spinal anesthesia for lower limb surgery.


Subjects and methods: Prospective clinical study on 30 cases with indications for lower limb surgery under spinal anesthesia with a mixture hyperbaric bupivacaine 0.5% 6-10mg and fentanyl 20mcg. Immediately after spinal anesthesia, patients were injected with ketamine 0.2 mg/kg intravenously to prevent shivering


Results: The rate of shivering during surgery was 10%, of which grade 2 shivering was 6.6% and grade 3 shivering was 3.3%. The postoperative shivering rate was 3.3% and was grade 2 shivering. During surgery, the rates of hallucination, nausea vomiting, bradycardia, tachycardia, hypotension, hypertension, headache, itching, dizziness, sedation with OAAS4  were 26.7%; 6.6%; 3.3%; 36.7%; 3.3%; 73.3%; 3.3%; 3.3%; 6.6%; 26.7%; respectively. After surgery, the rates of nausea vomiting, headache, itching were 9.9%; 6.6%; 3.3%, respectively.


Conclusion: Intravenous injection of ketamine 0.2mg/kg is effective in preventing shivering after spinal anesthesia for lower limb surgery with transient, easy-to-manage unwanted effects.
