ABSTRACT
BACKGROUND:
For patients sustaining major trauma, preinjury warfarin use may make adequate haemostasis difficult. This study aimed to determine whether preinjury warfarin would result in more haemostatic interventions (transarterial embolization [TAE] or surgeries) and a higher failure rate of nonoperative management for blunt hepatic, splenic or renal injuries.METHODS:
This was a retrospective cohort study from the Taiwan National Health Insurance Research Database (NHIRD) from 2003 to 2015. Patients with hepatic, splenic or renal injuries were identified. The primary outcome measurement was the need for invasive procedures to stop bleeding. One-to-two propensity score matching (PSM) was used to minimize selection bias.RESULTS:
A total of 37,837 patients were enrolled in the study, and 156 (0.41%) had preinjury warfarin use. With proper 12 PSM, patients who received warfarin preinjury were found to require more haemostatic interventions (39.9% vs. 29.1%, p=0.016). The differences between the two study groups were that patients with preinjury warfarin required more TAE than the controls (16.3% vs 8.2%, p = 0.009). No significant increases were found in the need for surgeries (exploratory laparotomy (5.2% vs 3.6%, p = 0.380), hepatorrhaphy (9.2% vs 7.2%, p = 0.447), splenectomy (13.1% vs 13.7%, p = 0.846) or nephrectomy (2.0% vs 0.7%, p = 0.229)). Seven out of 25 patients (28.0%) in the warfarin group required further operations after TAE, which was not significantly different from that in the nonwarfarin group (four out of 25 patients, 16.0%, p = 0.306)CONCLUSION:
Preinjury warfarin increases the need for TAE but not surgeries. With proper haemostasis with TAE and resuscitation, nonoperative management can still be applied to patients with preinjury warfarin sustaining blunt hepatic, splenic or renal injuries. Patients with preinjury warfarin had a higher risk for surgery after TAE.Palabras clave
