Abstract:
Objective:To compare the pain control efficiency of continuous adductor canal block (ACB) and femoral nerve block (FNB) in total knee arthroplasty.Methods:From April to September 2016,patients with severe knee osteoarthritis undergoing primary unilateral total knee arthroplasty (TKA) were prospectively observed,and all the patients were randomized received ultrasound-guided continuous ACB or FNB after surgery.Numeric pain rating scales (NPRS)pain scores in rest and activity 2,6,12,24 and 48 h after surgery were collected,and the preoperative and postoperative quadriceps strength at 24 and 48 h were analyzed.Opioids consumption and anesthesia related adverse effects were also recorded.Results:In the study,40 patients were enrolled,with 20 patients in each group,male ∶female =7 ∶ 33,the age:(63.8 ± 10.1) years,and the body mass index (BMI):(28.5 ± 3.5) kg/ m2.The general conditions were comparable between the two groups.Though the rest pain 2 h after surgery [ACB =0.0(0,6),FNB =3.0(0,5),P=0.004] and activity pain 12 h post operation [ACB =3.0(3,0),FNB =5.5(0,10),P =0.004] were lower in ACB group compared with FNB group,there was no statistical difference in the other pain checking points between the two groups.The quadriceps strength 24 h and 48 h after surgery were (85.3-± 27.6) N and (80.0 ± 30.1) N in ACB group,(69.0 ± 29.4) N and (64.4 ± 32.0) N in FNB group,both of them were declined by time.The exact data were higher in ACB group,however,there was no statistical difference between the two group by repeated measurements variance analysis(F =2.703,P =0.108).Four patients in ACB group and five in FNB acquired additional use of dolantin once (100 mg/per time) within 24 h.And among them,three patients acquired once dolantin in ACB,two in FNB,from 24 to 48 h postoperation.There were five patients who suffered nausea postoperation in ACB group,and one who reported xerostomia.Four patients in FNB had nausea with vomiting,and three experienced xerostomia.Deep vein thrombosis appeared in 2 patients in FNB group,but no one in ACB group.Conclusion:Continuous ACB is not superior in pain control after TKA compared with FNB,and the quadriceps strength could be reserved more by this method,which performed early benefits in fast rehabilitation.
