Application of femoral nerve block combined with modified swelling anesthesia in high ligation and stripping of great saphenous vein.

Background: To analyze and explore the clinical efficacy of ultrasound guided femoral nerve block combined with modified swelling anesthetic solution in high ligation and stripping of the great saphenous vein. Methods: 90 patients with varicose great saphenous vein of lower limbs undergoing high ligation and stripping of great saphenous vein were randomly divided into group A (femoral nerve block combined with modified swelling anesthesia), group B (simple swelling anesthesia) and group C (epidural anesthesia), with 30 patients in each group. The serum CRP level, operation duration, intraoperative blood loss, postoperative hospitalization time, total hospitalization cost, postoperative VAS score, preoperative and postoperative VCSS score, intraoperative mean arterial pressure and heart rate, postoperative related complications, and patients, satisfaction with diagnosis and treatment were compared among the three groups. Results: There was no significant difference in operation duration, intraoperative blood loss, postoperative complications, and preoperative and postoperative VCSS scores among the three groups ( Conclusions: Ultrasound guided femoral nerve block combined with modified swelling anesthetic solution applied in high ligation and stripping of the great saphenous vein can significantly improve postoperative inflammatory stress reaction of patients, effectively ensure the safety and reliability of surgical progress, help to improve analgesia effect and accelerate physical rehabilitation, and has short hospitalization time, low medical cost, and high satisfaction of patients' diagnosis and treatment, which is worthy of widespread clinical promotion and reference.
