目的:探讨迟发性血胸的病因及出现时间,及时治疗,预防并发症,降低病死率。方法:对271例血气胸病人中34例迟发性血胸伤因、机制、出血时间、治疗方法及结果综合分析。结论:①迟发性血胸多于伤后2～21天出现,出现前有诱因。②迟发性血胸多为少量积累、年龄大、耐受性高相对多,有胸外伤及可疑者最好X片随访2～3周。③迟发性血胸出血来源主要是肺挫伤,且肺挫伤和血胸存在着正相关关系。④迟发性血胸在血气胸治疗肺膨胀后仍可再次发生,临床应延迟拔管。⑤迟发性血胸出血量多少不等,治疗以多次反复穿刺为主。
Objective: To explore the etiology and time of delayed hemothorax, timely treatment, prevention of complications, reduce mortality. Methods: Thirty-four patients with hemopneumothorax were studied retrospectively. The causes, mechanism, bleeding time, treatment methods and results were analyzed. Conclusion: ① delayed hemothorax occurred more than 2 to 21 days after injury, before the emergence of incentives. ② more than a small amount of delayed hemothorax accumulation, age, tolerance is relatively high, chest X-ray and suspicious patients were followed up for 2 to 3 weeks. ③ The main source of delayed hemothorax bleeding is pulmonary contusion, and there is a positive correlation between pulmonary contusion and hemothorax. ④ delayed hemothorax in the treatment of pneumothorax may still occur again after lung expansion, clinical should be delayed extubation. Â’¤ delayed hemophagocytic bleeding amount, the treatment repeated repeatedly puncture based.
