Application of ultrasound-guided suprainguinal fascia iliaca block combined with general anesthesia with laryngeal mask in elderly patients undergoing surgery for great saphenous varicose veins

Objective To evaluate the application value of ultrasound-guided suprainguinal iliaca fascia block combined with general anesthesia with laryngeal mask in elderly patients undergoing surgery for the great saphenous varicose veins. Methods Sixty elderly patients scheduled for unilateral high ligation and stripping of the great saphenous veins combined with endovenous laser ablation were randomly divided into Group A （general anesthesia with laryngeal mask alone， <i>n = </i>30） and Group B （ultrasound-guided suprainguinal fascia iliaca block combined with general anesthesia with laryngeal mask， <i>n = </i>30）. Intraoperative anesthetic consumption， hemodynamic fluctuations， and laryngeal mask removal time were recorded. Postoperative changes in static and dynamic Visual Analogue Scale （VAS） pain scores， 15-item Quality of Recovery （QoR-15） scores， Mini-Mental State Examination （MMSE） scores， and adverse events were also evaluated. Results The QoR-15 and MMSE scores at postoperative 24 h in Group B were significantly higher than those in Group A （both <i>P &lt; </i>0.05）. The mean arterial pressure （MAP） and heart rate （HR） during skin incision in Group A were significantly higher than those in Group B （both <i>P &lt; </i>0.05）. The static and dynamic VAS pain scores at postoperative 5 min， 30 min， 6 h， and 12 h in Group B were significantly lower compared to those in Group A （all <i>P &lt; </i>0.05）. In Group B， the consumption of propofol and remifentanil was significantly less， and the laryngeal mask removal time was significantly shorter than those in Group A， with statistically significant differences （both <i>P &lt; </i>0.05）. Conclusion Ultrasound-guided suprainguinal fascia iliaca block combined with general anesthesia with laryngeal mask improves postoperative quality of recovery and cognitive function， reduces anesthetic consumption， shortens extubation time， enhances hemodynamic stability and alleviates postoperative pain， thereby promoting rapid recovery.
