Abstract:ObjectiveTo explore the risk factors of complications after emergency orthopaedic surgery.MethodsThe clinical data of 228 patients undergoing emergency orthopaedic surgery in Nanjing Drum Tower Hospital from July 2017 to July 2019 were retrospectively analyzed.The demographic data,preoperative concurrent diseases,anesthesia mode,operation type,operation time,infusion volume,blood loss,adverse events during operation and complications after surgery were collected.Univariate analysis was applied to explore the relationship between these clinical indicators and postoperative complications,and multivariate logistic regression model was used to analyze the risk factors of postoperative complications.ResultsIn 24 patients (10.5%) with major complications after operation,incision-related complications,respiratory complications and cardiovascular complications accounted for 37.5%,29.2% and 20.8%,respectively. Multivariate logistic regression model showed that age(OR=1.983,95%CI：1.754-2.112,P<0.01),American Society of Anesthesiologists (ASA) level (OR=1.597,95%CI:1.005-2.208,P<0.01) and intraoperative hypotension (OR=2.306,95%CI:1.514-3.070,P<0.01) were the independent risk factors for postoperative complications.ConclusionsAge,ASA level and intraoperative hypotension can be used as early warning [JP2]indicators for post-operative complications in patients receiving emergency orthopaedic surgery.Hemodynamic stability should be maintained as far as possible for anesthesia management in patients,to reduce the risk of post-operative complications.
