Abstract
Objective To observe and compare the anesthetic effects of small-dose and low-concentration ropivacaine hydrochloride and bupivacaine in spinal subarachnoid block (lumbar anesthesia) for mixed hemorrhoid surgeries. Methods Sixty patients who would be undergone mixed hemorrhoid surgeries in our hospital from July to December 2014,in ASAⅠ to II were evenly divided into two groups by random number table.Each group was carried out lumbar anesthesia through interspace between L3 and L4.In groupⅠ,0.25% ropivacaine hydrochloride in 7.5 mg was applied, while in group II,0.25% bupivacaine in 7.5 mg was adopted.The sensory block (by acupuncture),intraoperative rectal stretch reflex,the number of surgical patients evaluating relaxation of anal tube at the beginning of surgery,duration of anal tube relaxation,and recovery rate of anal contraction at the end of surgery was observed between two groups re-spectively. Results The level of sensory block in group Ⅰ was lower than that in group II,with a statistical difference (P<0.05).The reflectance of intraoperative rectal stretch in group Ⅰ was higher in comparison with that in group II, with a statistical difference (P<0.05).There was no statistical difference in satisfaction of anal tube relaxation at the be-ginning of surgery between two groups(P>0.05).The recovery time of anal contraction in group Ⅰ was(45±6) min,higher than that in groupII. Conclusion Both 0.25% ropivacaine hydrochloride in 7.5 mg and the same dose and concentra-tion of bupivacaine in spinal subarachnoid block for mixed hemorrhoid surgeries obtain favorable effects,and the former one used for spinal subarachnoid block can facilitate mixed hemorrhoid surgery,which is worthy of promotion.关键词
