问题 单项选择题

患者男,锅炉房工人,在锅炉爆炸事故后来院。患者明显呼吸困难,咯血,咳白色泡沫痰,血压偏低,神志淡漠。对此病人,急诊处理下列正确的是()

A.即刻予以大量补液

B.吸氧、积极对症处理,密切观察、抗感染

C.予以加压辅助呼吸

D.即刻术前准备,争取手术探查

E.没有开放性损伤,无法抗感染治疗

答案

参考答案:B

解析:考虑患者诊断为肺爆震伤,其病理生理改变为肺挫伤,肺毛细血管出血,小支气管和肺泡破裂,肺组织广泛性渗出而产生肺水肿。为避免肺水肿应控制补液量,同时由于小支气管、肺泡和肺血管沟通的存在,加压辅助呼吸容易引起气栓。患者通常不能耐受麻醉和手术创伤,为手术禁忌证。通常以吸氧、保持呼吸道通畅、抗感染、静养、对症处理等治疗为主。
