Title: The application of sufentanil combined with low-dose bupivacaine for spinal anesthesia in elderly patients
Abstract: Objective To investigate the effect of spinal anesthesia with different doses of sufentanil combined with low-dose bupivacaine in elderly patients. Methods Sixty patients undergoing abdominal or leg surgery were randomly divided into three groups with 20 cases each, all patients were received spinal anesthesia. Group Ⅰ:0.5% bupivacaine 7.5 mg+sufentanil 5 μg; group Ⅱ: 0.5% bupivacaine 7.5 mg + sufentanil 2.5 μg; group Ⅲ: 0.5% bupivacaine 10 mg. The onset time of sensory and motor block, the upper sensory block level, post-operative analgesia, the degree of motor block, hemodynamics and side effects were recorded. Results In groupⅠand Ⅱ the hemodynamics were more stable, the time of regression motor block were faster and nausea and dizziness were lower than that in group Ⅲ(P0.05). In groupⅠ the onset time of sensory block, reaching to the T10 dermatomes of time were shorter, and post-operative analgesia was longer than in groups Ⅱ, Ⅲ (P0.05).Conclusion Sufentanil combined with low-dose bupivacaine for spinal anesthesia in elderly patients can provide adequate sensory and motor block without hemodynamic instability.
