RESUMEN
Objective To compare the efficacy and side-effects of combined spinal-epidural anesthesia(CSEA)and epidural anesthesia(EA)for ureteroscopic pneumatic lithotripsy.Methods A total of 60 patients with ureteral calculi(ASA gradeⅠ-Ⅱ)were divided into A and B groups randomly(30 in each).CSEA was performed in group A,and EA was carried out in group B.Anesthetic effects and side-effects were observed in both the groups.Results Anesthetic effects were satisfying in both the groups,no patient had headache after the operation.The onset time of anesthesia in group A was shorter than that in group B [(7.2?4.1)min vs(17.4?3.3)min,t=-10.615,P=0.000].The level of motor block of CSEA was stronger than that of EA(?2=40.000,P=0.000).No significant differences were found between the two groups in the number of patients who developed hypotension(6 in group A and 3 in group B,?2=0.523,P=0.470)or shivering(9 in group A and 6 in group B,?2=0.800,P=0.371).Conclusions Both CSEA and EA are applicable to ureteroscopic pneumatic lithotripsy.CSEA is more efficient than EA.
