The analgesic effect of ultrasound guided fascia iliaca compartment block on postural changes in patients with the femoral neck fracture

Abstract

Objective To observe the analgesic effect of ultrasound guided fascia iliaca compartment block on postural changes in patients with the femoral neck fracture. Methods From January 2017 to November 2017, 60 patients with femoral neck fracture of American Society of Anesthesiologists(ASA) anesthesia grade Ⅱ-Ⅲ undergoing elective surgery in the Hospital of Yanqing District were selected, and they were divided into the ultrasound guided fascia iliaca compartment block group(F group) and the intravenous dezocine analgesia group(D group) according to the random number table, with 30 cases in each group.The F group received ultrasound guided fascia iliaca compartment block with 30 mL 0.45% ropivacaine mesylate, 30 min before entering the operating room.The D group received intravenous injection of dezocine 0.1 mg/kg, 10 min before entering the operating room.The VAS scores were recorded at entered the operating room(T1), overing the bed (T2), the position for intraspinal anesthesia(T3), and the occurrence of adverse reactions were observed. Results The VAS scores of the F group at T1, T2, T3 were lower than those of the D group[(2.07±0.52)points vs.(2.90±0.80)points, t=4.77, (2.80±0.61)points vs.(3.83±0.59)points, t=6.66, (3.83±0.65)points vs.(5.27±0.58)points, t=9.01], the differences were statistically significant(all P=0.00). There were no complications such as puncture site hematoma and local anesthetic toxicity in the F group.There were 8 dizziness patients (26.67%) and 4 nausea patients (13.33%) in the D group. Conclusion The analgesic effect of ultrasound guided fascia iliaca compartment block relative to intravenous drug on postural changes in patients with the femoral neck fracture is more obvious and has less adverse reactions, and it is suitable for clinical use.
