Effect of perioperative comprehensive pain nursing intervention for patients' rehabilitation after total knee arthroplasty

Objective To explore the rehabilitation effect of perioperative comprehensive pain nursing intervention for patients after total knee arthroplasty (TKA).Methods Totals of 100 patients who had TKA were randomly divided into the control group and the intervention group,each with 50 cases.The control group received conventional postoperative nursing while the intervention group received comprehensive pain nursing intervention in addition.Two groups' condition of recovery was observed and recorded.Results The pain scores 4,8,12,24,48 and 72 hours after surgery were respectively (3.12 ± 0.13),(2.35 ± 0.92),(2.42 ±1.23),(1.92 ±0.17),(1.65 ±1.17),(1.73 ±0.63) in the intervention group,and (4.80 ±0.30),(6.12 ±1.65),(7.42 ±2.09),(3.70 ±0.22),(3.80 ± 1.67),(3.48 ± 1.67)in the control group.The differences were statistically significant (t =4.72,13.77,14.73,14.09,8.23,7.69,respectively; P ＜ 0.01).The initiative straight-leg raising time and the initiative buckling of knee joint up to 90° time were obviously shorter in the intervention group than in the control group [(14.50 ± 1.90) h vs.(24.73 ± 3.04) h,(3.27 ± 0.73) d vs.(4.10 ± 1.05) d],and the differences were statistically significant (t =24.24,5.75,respectively ; P ＜0.01).The initiative active level of knee joint on discharge was much higher in the intervention group than in the control group [(106.46 ± 11.65) vs.(98.60 ± 11.36) °],and the difference was statistically significant (t =2.57,P ＜ 0.05).The satisfaction on discharge was also significantly higher in the intervention group than in the control group (x2 =63.25,P ＜ 0.01).Conclusions Comprehensive pain nursing intervention can reduce the postoperative pain and increase the comfort of TKA patients.It can also help the patients to do functional exercise as early as possible,promote early rehabilitation,improve nursing quality and improve patients satisfaction.
