Comparison Of FNB And FICB In Alleviating Pain Of Positioning Patients With Femoral Neck Fractures Before Spinal Anesthesia

Objective: This randomized controlled clinical study compared the effect of femoral nerve block(FNB)and fascia iliaca compartment block(FICB)on pain in patients with femoral neck fractures before spinal anesthesia.Method:Seventy-five patients with unilateral femoral neck fracture and planned partial or total hip replacement were selected.75 patients were randomly assigned to 3groups,25 in each group,namely,the FNB group,the FICB group,and F group.10 min before positioning for spinal anesthesia,patients received analgesia intervation.The FNB group was performed FNB with 15 m L of 0.5%ropivacaine under the guidance of ultrasound,the FICB group was performed FICB with 40 m L of 0.5% ropivacaine under the guidance of ultrasound,the F group patients received intravenous fentanyl 1.5μg/Kg.Patient’s pain were evaluated using a visual analogue scale(VAS)at rest and during hip flexion after admission to the operation room;at 3,5,8,10 min after analgesia intervention;and during positioning for spinal anesthesia.Positioning was attempted after 10 min of analgesia intervention in each group.Time required to perform spinal anesthesia,quality of position,patient satisfaction and adverse reactions were documented.Results: The VAS scores of the three groups decreased significantly after analgesia intervention.Compared with the F group,both the FNB group and the FICB group showed a lower VAS(P<0.05),better quality of position(P<0.05),shorter time to perform spinal anesthesia,higher patient’s satisfaction rates(P<0.05),and less adverse reactions(P<0.05).The average VAS in FNB group were lower than the FICB group at 3 and 5 min after the analgesic intervention(P <0.05),but there were no statistics differences in VAS at 8 and 10 min and during positinging between the two groups(P >0.05).Conclusion: Under the guidance of ultrasound,FNB and FICB produce good analgesic effects,which can significantly reduce the pain caused by positioning patients with femoral neck fractures.Compared with FICB,FNB has a faster onset of pain relief and less local anesthetics.
