PURPOSE: @entity358 ( @entity358 ) remains a major factor in morbidity and @entity204 in severely injured @entity1 , especially those in specific high-risk groups. PEs have been documented to occur despite routine @entity1150 prophylaxis. The purpose of this study was to evaluate the safety and efficacy of prophylactic Greenfield filter (PGF) placement in @entity1 who have @entity1230 with known high-risk injuries for @entity358 . METHODS: From January 1992 to June 1994, PGF were prospectively placed in 108 @entity1 who had an injury severity score greater than 9 and met one of the following criteria: (1) severe @entity542 with prolonged ventilator dependence, (2) severe @entity542 with multiple @entity174 , (3) @entity1566 with or without @entity912 , (4) major abdominal or pelvic penetrating @entity1317 , (5) pelvic @entity174 with @entity174 . These @entity1 were compared with 216 @entity1 , historically matched for age, sex, mechanism of @entity130 severity score, and days in the intensive care unit. Data analysis was done with chi-squared and Student's t testing. RESULT: There were no statistical differences between the PGF and control group with regard to age (35.9 +/- 1.5 vs 38.3 +/- 1.4), sex (male 76% vs 75.5%), days in the intensive care unit (21.2 +/- 1.4 vs 18.1 +/- 1.5), ISS (28.0 +/- 1.0 vs 25.4 +/- 0.8) and mechanism of injury (blunt 85% vs 81%). None of the @entity1 in the PGF group had a @entity358 . In the control group, however, 13 @entity1 had a @entity358 , nine of which were fatal. These differences were statistically significant for both @entity358 (p < 0.009) and @entity358 -related @entity204 (p < 0.03). The overall mortality rate was reduced in the PGF group (18 of 108, 16%) versus the control group (47 of 216, 22%); however, this did not achieve statistical significance. CONCLUSION: PGF insertion in selected @entity1 at high risk who had @entity130 effectively prevented both fatal and nonfatal @entity358 . The lower incidence of fatal @entity358 in the PGF group may have contributed to a reduction in the overall mortality rate. @entity1 who have @entity130 with high risk for @entity358 should be considered for PGF placement.
