Comparative analysis of analgesic effect of iliac fascial block with vertical and horizontal inguinal approach for total hip arthroplasty.

OBJECTIVE

To compare and analyze the analgesic effect of iliac fascial block with vertical and horizontal inguinal approach after total hip arthroplasty.

METHODS

78 patients who admitted to our hospital and underwent unilateral total hip replacement from January 2019 to June 2020 were enrolled and randomly divided into Group A (n=40) and Group B (n=38). 30 min before surgery, the group A received ultrasound-guided iliac fascial block by vertical inguinal approach, and group B underwent ultrasound-guided iliac fascial block with horizontal inguinal approach. Both groups received patient-controlled intravenous analgesia (PCA) postoperatively. Subsequently, the postoperative VAS scores, the cumulative postoperative PCA dosage of Sufentanil, the occurrence of postoperative adverse reactions, and the overall satisfaction scores of patients with anesthesia 24 h after surgery were compared accordingly.

RESULTS

The VAS score of Group A at 4 h, 8 h, 12 h, 24 h after surgery was remarkably lower than that of Group-B (). The cumulative Sufentanil dosage of PCA in Group A was substantially less than that in Group B (). The incidence of adverse reactions between the two groups of patients was statistically insignificant (). The satisfaction degree with anesthesia 24 h after surgery in Group A was notably higher than that in Group B ().

CONCLUSION

Compared with the horizontal inguinal approach, patients received iliac fascial block by vertical inguinal approach can achieve better postoperative analgesic effect for hip replacement. It helps to reduce Sufentanil dosage and improve the patient's satisfaction with analgesia, and thus safe for clinical application.
