Abstract:
Objective To investigate the incidence and risk factors of intraoperative deep venous thrombosis (DVT) in patients with multiple injuries.Methods A retrospective analysis was conducted of the 183 patients with multiple injuries who had been admitted to the Department of Orthopaedics and Trauma,Xi'an Honghui Hospital from January 2016 to November 2017.They were 117 males and 66 females,aged from 16 to 84 years (average,47.3 years).Craniocerebral injuries occurred in 16 cases,chest injuries in 24 cases,spinal injuries in 9 cases,pelvic acetabular fractures in 64 cases,upper limb fractures in 40 cases,and lower limb fractures in 145 cases.Venous ultrasonography of bilateral lower limbs was performed preoperatively and postoperatively to detect incidence of DVT.The patients were divided into a DVT group and a non-DVT group.The 2 groups were compared in terms of gender,age,interval from injury to surgery,D-dimer levels upon admission and discharge,operation time,intraoperative blood transfusion,injury severity scoring (ISS) and type of injury.After single-factor analysis was used to screen risk factors,multivariate logistic regression analysis was used to determine the main independent risk factors.Results The incidence of lower limb DVT in patients with multiple injuries was 42.08％ (77/183).Of the 77 DVT patients,12 had proximal thrombosis (6.56％) and 65 distal thrombosis (35.52％).Multivariate logistic regression analysis showed that age of ＞ 60 years,operative time for ≥2 hours,and presence of spinal injury were independent risk factors for DVT in patients with multiple injuries (P ＜ 0.05).Conclusions The incidence of lower limb DVT can be high in patients with multiple injuries.An age of ＞ 60 years,operation time for ≥2 hours and presence of spinal injury are independent risk factors for DVT in these patients.
