Title: A comparison of different intravertebral anesthetic techniques in elderly patients undergoing lower extremity surgery
Abstract: Objective To evaluate the efficacy and safety of different intravertebral anesthetic techniques in elderly patients undergoing lower extremity surgery. Methods Sixty ASA Ⅰ~Ⅲ patients ages 65~80yr undergoing lower extremity surgery were assigned to receive continuous epidural anesthesia (CEA group,n=20), combined spinal-epidural anesthesia (CSEA group, n=20), or continuous spinal anesthesia (CSA group,n=20). The anesthetic plane was under the level of T9. MAP, HR, and SpO2 at baseline value, the lowest level following anesthesia, 30 min after anesthesia, 60 min after anesthesia, and completion of anesthesia were measured in the three groups. The anesthetic efficacy and adverse events were recorded. Results As compared with the baseline, MAP decreased significantly within 30 min of anesthesia in all the groups(P 0.05) and its level was obviously lower in the patients receiving CSEA or CEA than in those receiving CSA(P 0.05). There were no differences in HR and SpO2 among all the groups. CSEA was similar with CSA in the onset of action, duration of blockade, and Bromage score and both of them were superior to CEA. More complications and adverse events occurred in the patients receiving CEA or CSEA than in those receiving CSA. Conclusions CSA is similar with CSEA in the anesthetic efficacy and has fewer adverse events than CSEA and CEA, which is more suitable for elderly patients.
