Abstract:
Objective To assess the anesthetic effect of different concentrations of hyperbaric ropivacaine used in lumbar anesthesia for elderly transurethral prostatic resection. Methods We randomly divided 58 elderly patients who un-derwent transurethral prostatic resection with ASA (American Surgical Association) physical status level Ⅰ-Ⅱ into 2 groups as group A and B, using numeric random table method. Each group includes 29 cases. After being punctured between L3-L4, patients were injected with 0.5%(group A) and 0.75%(group B) hyperbaric ropivacaine (diluted with 10%glucose) to the subarachnoid space in a speed of 0.1-0.3 mL/s and the overall dose was 12.5 mg in each case. Then the extents of sen-sory and motor block were compared between two groups, and their anesthesia effect and adverse reactions were also record-ed. Results Compared with group A, onset time of sensory block in group B was significantly shorter (P＜0.05), while onset time for motor block was of no significant difference;By contrast to group A, acting time of sensory block in group B pro-longed significantly (P＜0.05) while acting time of motor block was of no statistically significant difference(P>0.05);By con-trast to group A, the anesthesia effect of group B was more effective while the adverse reactions of the two groups was of no significant difference (P>0.05). Conclusion 0.75%hyperbaric ropivacaine in lumbar anesthesia for elderly patients un-dergoing transurethral prostatic resection could provide a better anesthesia and analgesia effect than 0.5%hyperbaric ropiva-caine without more significant adverse reactions.
