Application of ultrasound-guided high fascia iliac compartment block in arthroscopic knee surgery
Objective:To compare the clinical effects of high fascia iliac compartment block and femoral nerve combined with sciatic nerve block in knee arthroscopy.Methods:A total of 44 patients who underwent knee arthroscopy were selected and randomly divided into two groups:high fascia iliac compartment block(group A)and femoral nerve combined with sciat-ic nerve block(group B).The onset time of sensory and motor block,patient satisfaction during the two types of nerve block puncture,the number of effective postoperative analgesic pump press and the dosage of supplementary analgesic drugs were compared between the two groups.Resting visual analogue scale(VAS)and VAS scores of 5-meters walking test after entering the operating room(T0),2 hours after surgery(Ti),6 hours after surgery(T2),12 hours after surgery(T3)and 24 hours after surgery(T4).The muscle strength of the affected quadriceps muscle on T2,T3 and T4 and the occurrence of postoperative adverse events such as nausea,vomiting and dizziness.Results:The onset time of sensory nerve block in group A was significantly shorter than those of patients in group B,and the satisfaction of patients during nerve block puncture in group A was signifi-cantly higher than that in group B(P＜0.05).The resting VAS scores of patients in group A were significantly lower and the quadriceps strength scores were significantly better than those of group B at 6 hours and 12 hours after surgery,while the VAS scores of the 5-meters walking test were significantly lower(P＜0.05)in group A compared with those of group B.The number of postoperative analgesic pump presses and the dosage of remedial analgesic drugs in group A were lower than those in group B,and the first time of getting out of bed was earlier than that in group B(P＜0.05).Conclusion:Compared with the femoral nerve combined with sciatic nerve block composite general anesthesia,ultrasound-guided high fascia iliac compart-ment block composite general anesthesia has a better analgesic effect on patients who underwent knee arthroscopy,which can rapidly block sensory nerves,reduce VAS score,reduce the number of analgesic pump dosages,reduce the amount of anal-gesic drugs,and have a smaller impact on lower limb muscle strength.It can promote the early recovery of patients.
