Abstract:
Objective To evaluate the safety,efficacy and comfort of dexmedetomidine sedation combined with ultrasound-guided ilioinguinal and ilioinguinal nerve block in open inguinal hernia surgery for elderly patients with underlying diseases.Methods 40 elderly patients for open inguinal hernia surgery with underlying diseases were selected and randomly divided into group A and group B.Group A recived simple nerve block,while group B recived dextropyrimidine sedation combined with nerve block.The heart rate (HR),mean arterial pressure (MAP),SpO2,Ramsay sedation score and visual analogue score (VAS) at T0 (entering operating room),T1 (anesthesia puncture),T2 (15 min after anesthesia),T3 (surgical incision),T4 (hernia sac free),T5 (operation ending) in both two groups were recorded,and the intraoperative anesthesia effect were evaluated.The satisfaction rate,incidence of bradycardia,bradycardia and respiratory depression were compared between the two groups;and observed the sufentanil using,lidocaine using and the occurrence of adverse reactions.Results There was no significant difference of SpO2 at each time point between the two groups (P ＞ 0.05);HR,MAP and Ramsay sedation scores at T0 between the two groups had no significant difference (P ＞ 0.05);compared with group A,HR,MAP and Ramsay scores at T1-T5 in group B decreased and Ramsay scores increased,while VAS at T1,T3,T4 and T5 in group B were lower (P ＜ 0.05);in group B,local anesthesia with lidocaine at puncture point,intraoperative sufentanil and body movement were significantly reduced,and the overall satisfaction rate of patients was high (P ＜ 0.05).There were no obvious adverse reactions in both groups.Conclusions Dexmedetomidine sedation combined with ilioinguinal/iliohypogastric nerve block is safe and effective in elderly patients with open hernia surgery combined with basic diseases,and it can improve the comfort of patients during anesthesia puncture and operation more than simple nerve block.
