Influence factors of debilitating and nutritional risk on complications of primary hip replacement / 中国骨伤

ABSTRACT

OBJECTIVE@#To analyze relationship of debilitating and nutritional risk on complications of primary hip replacement, and risk factors of influence of complications of primary hip replacement.@*METHODS@#Totally 100 patients who underwent hip replacement from January 2019 to January 2021 were retrospectively analyzed, including 36 males and 64 females, aged from 18 to 85 years old with an average of (73.82±4.04) years old. Postoperative frailty status was evaluated by modified frailty index, and nutritional status was evaluated by clinical biochemical indexes and NRS2002 nutritional risk assessment scale. One hundred patients were divided into frailty group and non-frailty group according to modified frailty index, 100 patients were divided into normal nutrition group and nutritional risk group according to nutritional status, and relationship between frailty, nutritional risk and complications after primary hip replacement was analyzed.@*RESULTS@#There were significant differences in age, body mass index (BMI), complications and ASA grade between frailty group and non-frailty group(P<0.05). There were statistically significant differences in age, BMI, complications and ASA grade between normal nutrition group and nutritional risk group (P<0.05). Thirty-five patients occurred at least one postoperative complications, and the incidence of pulmonary infection was the highest, accounting for 34.29% (12/35). The second was urinary infection, accounting for 22.86%(8/35). Univariate Logistic regression analysis showed that age, BMI, ASA grade, complications, frailty and nutritional risk were the risk factors for postoperative complications. Multivariate Logistic regression analysis showed that complications, frailty and nutritional risk were independent factors affecting postoperative complications.@*CONCLUSION@#Patients with comorbidities, frailty and nutritional risk could increase the incidence of complications. Timely assessment and identification of these patients in time, and formulation of targeted intervention measures have great clinical significance.
