AbstractObjective:To determine the prevalence of deep vein thrombosis (DVT) by surveillance duplex ultrasound in the traumatic spinal cord injury (SCI) population on admission to rehabilitation.Design:Retrospective sequential case series.Setting:Midwest regional, university-based, Commission on Accreditation of Rehabilitation Facilities-accredited acute rehabilitation center.Methods:Charts of all patients with traumatic SCI admitted and discharged from january 1, 1996 through December 31, 1998 were reviewed. Preadmission data were collected on demographics, severity of injury, and DVT prophylaxis information, along with rehabilitation duplex ultrasound results and incidence of thromboembolic events.Results:Ninety-two participants met the inclusion criteria. There were 68 men and 24 women with a mean age on admission of 3 2.4 years. On admission, 45 participants (49%) were classified as tetraplegic and 47 (51%) were classified as paraplegic; 63 (69%) had motor-complete lesions and 29 (31 %) had motor-incomplete lesions. Of all the participants, 8 (8.7%) were found to have DVT on admission to rehabilitation. There were no statistically significant differences among participants with regard to age, sex, level of injury, or completeness of injury, when comparing those participants with DVT on admission, those without DVT on admission, and those with thromboembolic events diagnosed later in their hospitalization. Of the 84 participants who had negative duplex ultrasounds on admission, 4 individuals (4.8%) were found to have DVT and 4 (4.8%) had pulmonary emboli subsequently. In these 84 participants, DVT prophylaxis with low-molecular-weight heparin was found to be more effective than was adjusted-dose heparin in preventing thromboembolic phenomenon.Conclusion:Incidence of DVT remains high despite prophylaxis in traumatic SCI patients. Two thirds of DVT diagnosed in rehabilitation was identified on admission and one third was diagnosed later. Duplex ultrasound is an effective and valuable tool that assists in the diagnosis of asymptomatic DVT in patients with traumatic SCI who are initiating in -patient rehabilitation. |
