Abstract:
Objective:To analyze the epidemiological characteristics and influencing factors of venous thrombosis in elderly patients with severe trauma.Methods:A retrospective study was conducted to collect and statistically analyze general information[sex, age, body mass index(BMI)], causes of trauma, injury severity score(ISS), Glasgow coma score(GCS), coagulation function[prothrombin time(PT), international normalized ratio(INR), D-dimer], B-type natriuretic peptide(BNP), liver function(alanine aminotransferase, aspartate aminotransferase), creatinine, Caprini score, surgical approach, immobilization mode, days of hospitalization, and treatment cost.Results:Totally 179 elderly patients with severe trauma were enrolled, including 130 men(72.6%), aged(67.6±6.4)years.The BMI, ISS and GCS scores of elderly patients with severe trauma were(22.9±3.4)kg/m 2, 28.4±10.5 and 10.2±4.6, respectively.The Caprini score was 11.7±4.0.Of these patients, 32(17.9%)had VTE events.Compared with the VTE negative group, the VTE positive group was older( t=-2.214, P=0.028), with a higher Caprini score( t=-2.684, P=0.008)and more lower limb fractures( P=0.008)and pelvic fractures( P=0.001). There were no significant differences in coagulation function, liver function, atrial natriuretic peptide levels, creatinine levels and surgical approaches between the VTE negative group and the VTE positive group(all P<0.05). No significant difference was found in the proportion of patients receiving surgical treatment between the two groups( P=0.563). In the VTE positive group, 18.8% had no fracture, 50.0% had one fracture, and 31.2% had two or more fractures, and the difference was statistically significant compared with the VTE negative group( P=0.029). However, VTE events had no significant effect on the average length of stay and hospitalization costs in elderly trauma patients(all P<0.05). Conclusions:For elderly patients with severe trauma, VTE is more likely to occur with increased age, a high Caprini score, multiple fracture sites and pelvic fracture.In addition, pelvic fracture is an independent risk factor for VTE in very old trauma patients.Attention should be paid to prevention and treatment to achieve steady improvement in the overall prognosis of trauma in these patients.
