Objective    To investigate the role of 64-slice helical CT in treatment of multiple trauma.     Methods    A retrospective study was carried out on 284 cases of multiple trauma including 232 males and 52 females (with average age of 34.5 years) admitted from January 2006 to October 2007 in our hospital. Injury sites and injury frequency were distributed at head and neck in 54 cases/times

face in 35

thoracic region in 125

abdomen in 112

pelvis and extremities in 104 and body surface in 254. Of all

103 cases/times were combined with shock. Their traumatic condition evaluated by injury severity score (ISS) was 10 to 54 points

mean 16.3 points. Of all

37 cases were sent for operation directly because of severe injury

the other 247 cases were examined with 64-slice helical CT within 3 h after admission.     Results    Mean time of 64-slice helical CT scanning was 8.4 min. Misdiagnosis happened in 21 cases. Emergency operation was done in 154 cases

of which 74 cases received operation via free channel. A total of 130 cases were treated non-surgically. Of all

272 cases (95.8％) survived but 12 (4.2％) died.     Conclusion    Application of 64-slice helical CT in early treatment of multiple trauma is helpful for shortening preoperative time and improving early definite diagnosis and management.
