Application effect of femoral nerve block combined with intra-articular anaesthesia in knee arthroscopy
Objective To evaluate the effect and safety of femoral nerve block combined with intra-articular anaesthesia in knee arthroscopy.Methods A total of 120 patients who planned to undergo unilateral knee arthroscopic surgery due to meniscus injury,loose body,or osteoarthritis in Department of Bone and Joint Surgery,Binzhou Medical University Hospital from January to June 2022 were selected.The patients were randomly divided into a femoral nerve block combined with joint cavity infiltration anesthesia group(F/I group)and a combined spinal-epidural anesthesia group(CSEA group),with 60 patients in each group.In the F/I group,there were 32 males and 28 females,aged(38.75±11.35)years.In the CSEA group,there were 25 males and 35 females,aged(37.80±10.85)years.The differences in the number of intraoperative rescue cases,postoperative Visual Analogue Scale(VAS)score,postoperative sensory recovery time,first ambulation time,postoperative complications,hospitalization cost,and length of hospital stay were compared between the two groups.ttest,x2 test,and Fisher exact probability method were used.Results The VAS score of the F/I group 6 h after operation was lower than that of the CSEA group[(2.08±0.61)points vs.(2.54±0.64)points],with a statistically significant difference(t=-2.484,P=0.018).The sensory recovery time of the F/I group was longer than that of the CSEA group[(6.25±0.40)h vs.(3.60±0.31)h],and the first ambulation time was shorter than that of the CESA group[(2.99±1.05)h vs.(8.14± 1.88)h],with statistically significant differences(t=14.095 and-12.263,both P＜0.001).The postoperative complications:the incidence of intraoperative anesthesia in the F/I group was 3.3％(2/60),the incidence of urinary retention was 0,the incidence of lower extremity venous thrombosis was 1.7％(1/60),and the incidence of nausea and vomiting was 3.3％(2/60);in the CSEA group,the incidence of postoperative anesthesia was 0,the incidence of urinary retention was 10.0％(6/60),the incidence of lower extremity venous thrombosis was 5.0％(3/60),and the incidence of nausea and vomiting was 16.7％(10/60);there were statistically significant differences in the incidence of urinary retention and nausea and vomiting between the two groups(both P＜0.05).The length of hospital stay and hospitalization cost in the F/I group were(3.90±0.63)d and(9 612.67±507.15)yuan,and those in the CESA group were(5.27±0.75)d and(11 401.52± 530.01)yuan,with statistically significant differences(t=-8.862 and-15.425,both P＜0.001).Conclusion Femoral nerve block combined with intra-articular infiltration anesthesia in knee arthroscopic surgery can reduce the postoperative complications,shorten the length of hospital stay,reduce the cost of hospitalization,and provide a good anesthetic effect.
