Abstract:Objective To compare the influence of fascia iliaca block (FIB) under ultrasound and intraspinal anesthesia on anesthesia placement position and postoperative analgesia in patients with hip fractures. Methods A total of 83 patients with hip fractures admitted to Wuhu Hospital of Traditional Chinese Medicine from July 2022 to August 2023 were selected and divided into clinical group (41 cases) and control group (42 cases). The clinical group received FIB combined with intraspinal anesthesia, and the control group was given intraspinal anesthesia. Anesthesia effect, perioperative visual analogue scale (VAS) score, fracture recovery Bromage score, dosage of anesthetic drug within 48 h after surgery and occurrence of anesthesia adverse reactions were compared between the two groups. Results The total effective rate of anesthesia in clinical group was 95.12%, which was higher than 78.57% in control group (χ²=4.943, P=0.026). VAS scores in clinical group at the time of changing position and at 6, 12, 24 and 48 h after surgery were lower than those in control group (P＜0.05). The Bromage scores in clinical group at 30 min after analgesia and 12 h to 48 h after surgery were lower than those in control group (P＜0.05). The number of analgesic pump compression and dosage of sufentanil citrate within 48 h in clinical group were significantly lower than those in control group (P＜0.05). There was no significant difference in adverse reactions between the two groups (χ²=0.001, P=0.970). Conclusion FIB has a good analgesia effect during anesthesia placement position and at rest, and it can accelerate the postoperative lower limb muscle strength and hip function recovery, and it is a safe and effective method to relieve pain in patients with hip fractures.
