Application of Ultrasound-guided Nerve Blockade Combined with General Anesthesia in Lower Limb Fracture Surgery / 医学研究杂志

ABSTRACT

Objective To explore the application of ultrasound-guided femoral and sciatic nerve blocks combined with general anesthesia in lower limb fracture surgery.Methods Sixty four patients who received orthopaedics surgerywere randomly divided into two groups including combined group(n =32),control group (n =32).Control group was given general anesthesia alone,combined group was givengeneral anesthesia combined with ultrasound-guided femoral and sciatic nerve blocks.The intraoperative hemodynamic state at different time,anesthetic dosage,and agitation after waking upbetween two groups were compared.Results Compared with T1 moment,HR and MAP at T2 moment in both groups were significantly decreased (P ＜ 0.05),while all these indicators at T3-T5 moment had no significant difference compared with the T1 moment in combined group (P ＞ 0.05),while the difference was significant in control group (P ＜ 0.05).Compared with control group,combined group had less intraoperative propofoland fentanyl dosage during the surgery,shorter awakening timeand extubation time,and the difference had statistical significance (P ＜ 0.05).The incidence of agitation after waking up and degree of agitation was significantly decreased in combined group than that in control group (P ＜ 0.05).Conclusion Ultrasound-guided nerve blockade combined with general anesthesia for lower limb fracture surgery,canmaintain the stability of intraoperative hemodynamics,reduce the dosage of analgesic drugs,and promote early awakening and extubation.
