IntroductionAlthough critically ill children may be at risk from developing deep venous thrombosis (DVT), data on its incidence and effectiveness of thromboprophylaxis are lacking.ObjectiveTo describe the use of thromboprophylaxis in critically ill children in Spain and Portugal, and to compare the results with international data.Material And MethodsSecondary analysis of the multinational study PROTRACT, carried out in 59 PICUs from 7 developed countries (4 from Portugal and 6 in Spain). Data were collected from patients less than 18 years old, who did not receive therapeutic thromboprophylaxis.ResultsA total of 308 patients in Spanish and Portuguese (Iberian) PICUS were compared with 2176 admitted to international PICUs. Risk factors such as femoral vein (P=.01), jugular vein central catheter (P<.001), cancer (P=.03), and sepsis (P<.001), were more frequent in Iberian PICUs. The percentage of patients with pharmacological thromboprophylaxis was similar in both groups (15.3% vs. 12.0%). Low molecular weight heparin was used more frequently in Iberian patients (P<.001). In treated children, prior history of thrombosis (P=.02), femoral vein catheter (P<.001), cancer (P=.02) and cranial trauma or craniectomy (P=.006), were more frequent in Iberian PICUs. Mechanical thromboprophylaxis was used in only 6.8% of candidates in Iberian PICUs, compared with 23.8% in the international PICUs (P<.001).ConclusionsDespite the presence of risk factors for DVT in many patients, thromboprophylaxis is rarely prescribed, with low molecular weight heparin being the most used drug. Passive thromboprophylaxis use is anecdotal. There should be a consensus on guidelines of thromboprophylaxis in critically ill children.Copyright © 2014 Asociación Española de Pediatría.
