Risk factors of perioperative heart failure in elderly patients with femoral neck fracture after hip joint replacement / 中华创伤杂志

ABSTRACT

Objective To investigate the risk factors of perioperative heart failure in the elderly patients with femoral neck fracture treated with hip joint replacement so as to provide relevant clinical reference.Methods A retrospective case control study was conducted to analyze the clinical data of 155 elderly patients with femoral neck fractures who underwent total hip or hemiarthroplasty in Wenzhou Traditional Chinese and Western Medicine Hospital from May 2012 to August 2016.There were 62 males and 93 females,aged (75.6 ± 7.4)years.The patients were divided into heart failure group (26 patients)and non heart failure group (129 patients).Heart failure group included 10 males and 16 females,aged (78.3 ± 8.2)years.There were 52 males and 77 females in the non heart failure group,aged (74.5 ±6.7) years.Information including age,gender,history of hypertension,history of heart diseases,American Society of Anesthesiologists (ASA) physical status classification,duration from injury to surgery,preoperative renal function,perioperative fluid balance,operation method,operation time,postoperative pain score,perioperative blood loss,and constipation were collected.Univariate analysis was firstly performed on the above data,and multivariate logistic regression analysis was conducted on the significant factors generated by the univariate analysis so as to identify independent risk factors for perioperative heart failure.Results According to the univariate analysis,age,history of heart diseases,preoperative renal function,and perioperative fluid balance were statistically different between the two groups (P ＜ 0.05).Multivariate analysis results showed that the independent risk factors of perioperative heart failure included age (OR =5.351,95％ CI 1.459-19.623,P ＜ 0.01),history of heart diseases (OR =5.717,95 ％ CI 2.399-13.624,P ＜ 0.01),preoperative renal function (OR =2.670,95％ CI 1.125-6.336,P ＜ 0.05),perioperative fluid balance (OR =2.980,95％ CI 1.287-6.899,P ＜0.01).Conclusions Age,history of heart diseases,preoperative renal function,and perioperative fluid balance are the risk factors of perioperative heart failure in elderly patients with femoral neck fracture.Therefore,more attention should be paid to these risk factors and corresponding preventative measures should be taken to reduce the incidence of perioperative heart failure.
