RESUMEN
Objective To investigate the standards for management of traumatic intrapulmonary hematoma and hematocele.Methods A retrospective study was conducted on the data of 21 patients with traumatic pulmonary hematoma or hematocele (AIS≥4 points) treated at Chongqing Emergency Medical Center from August 1999 to August 2010.Results The overall mortality was 14％ (3/21)and death causes were respiratory passage hemorrhea and asphyxia.About 67％ of patients ( 14/21 ) were associated with hemoptysis,which lasted for 1-240 days (mean,15.8 days).The duration of hemoptysis due to traumatic intrapulmonary hematoma hematocele was about 3.4 times longer than that due to simple traumatic pneumatocele.The hematoma or cyst disappeared at average 61.6 days,with 3.4 times longer than the disappearance time of intrapulmonary hematoma or hematocele in comparison with that of simple pneumatocele.The size and position of traumatic pulmonary hematoma or pneumatocele influenced the treatment methods,outcomes and prognosis.Conclusions Standardized treatment for traumatic pulmonary hematoma or hematocele is key to improving the cure rate.Early emergency definitive surgery is required for patients with traumatic intrapulmonary hematoma or hematocele greater than 6.0 cm in diameter and for those with pneumatocele greater than 6.0 cm in diameter combined with incapability of keeping breathing due to severe air leakage.
