Early versus delayed thromboprophylaxis with LMWH in pelvic-acetabular trauma- a prospective study.

BACKGROUND

Delayed presentation of pelvic-acetabular fractures is a common scenario in developing countries and there is usually a delay of more than 24 h in their presentation.

OBJECTIVES

We aim to comparatively analyse early(<24 h) versus delayed (>24 h) thromboprophylaxis with low molecular weight heparin (LMWH) in prevention of deep venous thrombosis (DVT) in Pelvic Acetabular fractures.

METHODS

Patients of pelvic-acetabular fractures who presented during 1 year of study period were divided into 2 groups after exclusion of patients with contraindications for thromboprophylaxis. Group A included patients who received LMWH prophylaxis within 24 h of injury. Group B included patients who received LMWH prophylaxis after 24 h of injury. All patients underwent CT venography at day 14 and were followed up with doppler ultrasound on 4th and 8th week.

RESULTS

110 patients with pelvic-acetabular fractures were included after exclusion of 61 patients. 4 out of 29 patients in group A (13.8%) and 12 out of 81 patients (14.8%) in group B developed DVT. There was no significant difference in incidence of DVT between Group A and B (P value-0.893).

CONCLUSION

There was no difference between early and delayed thromboprophylaxis with LMWH in pelvic-acetabular trauma.
