Resumo

Contexto: Pacientes com trauma pélvico apresentam elevado risco de trombose venosa profunda, enquanto o início precoce da tromboprofilaxia pode aumentar o risco hemorrágico em indivíduos hemodinamicamente instáveis. O momento ideal para introdução da anticoagulação permanece controverso.

Objetivos: Avaliar se o início tardio da profilaxia farmacológica está associado à ocorrência de trombose venosa profunda em pacientes com trauma pélvico após ajuste para idade e ativação do protocolo de transfusão maciça.

Métodos: Estudo observacional de coorte retrospectiva, conduzido em um centro de trauma de nível I entre janeiro de 2022 e dezembro de 2023, incluiu pacientes adultos com trauma pélvico. A exposição principal foi início da tromboprofilaxia farmacológica em até 48 horas (precoce) versus após 48 horas (tardia). O desfecho primário foi ocorrência de trombose venosa profunda durante a internação. Realizou-se regressão logística multivariada ajustada para idade e ativação do protocolo de transfusão maciça.

Resultados: Analisaram-se 62 pacientes, com idade média de 47,71±19,91 anos, e predominância do sexo masculino (66,1%). A incidência global de trombose venosa profunda foi de 32,3% (n = 20). Na análise bivariada, a incidência foi de 35,3% no grupo de início tardio e 28,6% no grupo de início precoce (p = 0,598). Na análise multivariada, o início precoce não se associou independentemente à ocorrência de trombose venosa profunda (odds ratio 0,65; intervalo de confiança de 95% 0,21-2,00; p = 0,456).

Conclusões: O início tardio da tromboprofilaxia não apresentou associação independente com maior incidência de trombose venosa profunda após ajuste para idade e ativação do protocolo de transfusão maciça.

Abstract

Background: Patients with pelvic trauma are at high risk for deep vein thrombosis (DVT), but early initiation of thromboprophylaxis may increase bleeding risk in hemodynamically unstable individuals. The optimal timing for initiation of anticoagulation remains controversial.

Objectives: To evaluate whether delayed initiation of pharmacologic prophylaxis is associated with a higher incidence of DVT in patients with pelvic trauma, after adjustment for age and activation of the massive transfusion protocol.

Methods: This retrospective observational cohort study was conducted at a Level I trauma center from January 2022 to December 2023. Adult patients with computed tomography–confirmed pelvic trauma who underwent Doppler ultrasonography during hospitalization were included. The primary exposure was initiation of pharmacologic prophylaxis within 48 hours (early) vs. after 48 hours (delayed). The primary outcome was occurrence of DVT during hospitalization. Multivariable logistic regression was conducted, adjusting for age and activation of the massive transfusion protocol.

Results: A total of 62 patients were analyzed, with a mean age of 47.71 ± 19.91 years and predominance of male sex (66.1%). The overall incidence of DVT was 32.3% (n=20). In the bivariate analysis, DVT incidence was 35.3% in the delayed group and 28.6% in the early group (p = 0.598). In the multivariable analysis, early initiation was not independently associated with the occurrence of DVT (OR 0.65; 95% CI 0.21–2.00; p = 0.456).

Conclusions: O início tardio da tromboprofilaxia não apresentou associação independente com maior incidência de trombose venosa profunda após ajuste para idade e ativação do protocolo de transfusão maciça.
