在随机试验中的天然猪表面活性剂和合成表面活性剂的疗效进行了比较。在三个新生儿重症监护病房,新生儿呼吸窘迫和228的比例为动脉肺泡氧分压<0.22被随机分配到接受或固尔苏100 mgkg-1或Exosurf新生儿5 ml.kg-1。固尔苏后,吸入氧浓度从15分钟(0.45 + / - 0.22和0.70 + / - 0.22,P = 0.0001),以6小时(0.48 + / - 0.26和0.64 + / - 0.23,P = 0.0001)的平均气道压力较低,为1小时(8.3 + / - 3.2毫米H20和9.4 + / - 3.1毫米H20,P = 0.01)。此后的呼吸参数是相似的。固尔苏和Exosurf的机械通气的持续时间(中位数为6比5天)和持续时间(中位数为5比4 D)补充氧气。在固尔苏,C-反应蛋白值超过40毫克L-1发生在45%(对12%,RR = 3.62,95%CI 2.12-6.17,P = 0.001),白细胞减少症的52%(比28%,RR 1.85, 95%CI 1.31-2.61,P = 0.001)和菌血症,11%(相对于4%; RR 3.17,95%CI 1.05-9.52,P <0.05)。我们得出结论,当抢救治疗固尔苏,除了最初的反应,更有效地与Exosurf相比并无优势。固尔苏可能会增加感染的风险。
