[Analysis of risk factors of multiple fractures of limbs complicated with pleural effusion].

OBJECTIVE

To explore the risk factors of limb fracture complicated with pleural effusion, and to provide reference for the prevention of pleural effusion.

METHODS

From January 2010 to December 2019, 137 patients with multiple limb fractures were treated surgically, including 102 males and 35 females, aged 16 to 92(48.34±15.85) years. Multiple limb fractures were defined as more than two limb fractures in the whole body, so the selected patients had complete clinical, impact and laboratory examination data before operation, including preoperative chest CT, gender, age, body mass index(BMI), hematocrit(HCT), American Society of Anesthesiologists(ASA), injury severity score (ISS), smoking history of operation, history of diabetes, history of hypertension, admission to operation time, fracture site, platelet count, albumin, C-reactive protein and D-dimer. Whether the patient was complicated with pleural effusion, calculate the amount of pleural effusion were recorded, and the relevant risk factors were statistically analyzed.

RESULTS

All limb fractures received surgical treatment. The incision healed well after operation, and there were no complications such as wound infection, acute lung injury or acute respiratory distress syndrome. Multivariate regression analysis showed that ISS higher than 16(P=0.000), smoking history(P=0.001) and rib fracture(P=0.000) were the risk factors of multiple limb fractures complicated with pleural effusion. Multivariate linear regression analysis showed that smoking history, ISS and rib fracture were the risk factors for the increase of pleural effusion in multiple limb fractures.

CONCLUSION

Multiple fractures of limbs combined with pleural effusion are related to ISS, smoking history and rib fracture;the amount of pleural effusion was related to smoking history, ISS and rib fracture. Patients with multiple fractures with ISS greater than 16, smoking history or rib fracture should be vigilant and intervene as soon as possible to reduce the risk of pleural effusion.
