To observe the implementation effect of standardized pain management in perioperative period of total knee arthroplasty.

A total of 152 patients who underwent total knee arthroplasty were enrolled by prospective collection in the Zhongshan Hospital affiliated to Dalian University from August 2016 to December 2017. Random digital table method was used. Patients were randomly divided into the routine nursing group and the pain management group. Routine care was given to the routine care group. The pain management group used perioperative standardized pain management. The KSS scores, pain scores, first time to go to the hospital and hospital stay, postoperative knee flexion≥90° and nursing satisfaction were compared between the two groups.

On the 7th postoperative day, the KSS score (89±6), pain score (4.4±1.6), the first ground time (22±4) and hospitalization time (7.3±2.6) in pain management group were all significantly lower than that of the conventional nursing group [KSS score was (85±6), pain score was (7.4±2.5), the first ground time was (35±5), hospitalization time was (15.7±6.9)], the differences were statistically significant (t=30.541, P=0.009; t=12.541, P<0.001; t=13.059, P<0.001; t=7.022, P<0.001). The satisfaction rate of nursing in the pain management group (94.7%) was significantly higher than the routine nursing group (78.9%), the difference was statistically significant (χ²=10.894, P<0.05).

The standardized pain management has a significant effect in the perioperative period of total knee arthroplasty. It can effectively improve the quality of life of patients, improve the prognosis of patients and promote the recovery of patients. It is worthy of clinical application and promotion.
