Results presented as mean ± standard deviation, as median (25th to 75th quartiles) or as number of patients (%). AIS, Abbreviated Injury Scale; Al, aliphatic polyurethane; Ar, aromatic polyurethane; GSC, Glasgow Coma Score; ICHT, intracranial hypertension; ISS, Injury Severity Score; SAPS II, Simplified Acute Physiologic Score II on ICU admission; SCVC, subclavian central venous catheter.
