问题 单项选择题 A1/A2型题

烧伤休克期的尿量往往减少,以下哪些是正确的。()

A.成人尿量在20~30ml/h情况下,往往提示输液量比较合适

B.成人尿量在30~50ml/h情况下,往往提示输液量比较合适

C.成人尿量在>50ml/h情况下,往往提示输液量比较合适

D.发现尿量减少时,往往需立即使用利尿剂

E.发现尿量减少时,往往已有严重肾功能损害

答案

参考答案:C

解析:

休克期复苏时,成人尿量不宜低于30ml/h,至少应保持30~50ml/h,最好保持在50ml/h以上。发现尿量减少时,一般情况下,往往提示液体输入量不足,首先宜加快输液速度,进一步观察,而不是立即给予利尿剂。在有效循环血量不足的情况下给予利尿剂,往往效果不佳;或者尿量虽短期改善,但休克加重。早期的尿量减少,往往肾功能尚未严重受损,但若不及时处理,持续的肾脏低灌注,可逐渐加重肾功能损害。
