Recent studies have questioned the use of histamine (H2) receptor antagonist in stress ulcer prophylaxis because of an increased incidence of nosocomial pneumonia and subsequent death.
This prospective randomized study compared prophylaxis with cimetidine vs sucralfate.
Medical/surgical intensive care unit in Springfield, Mass.
One hundred fourteen patients were enrolled.
Cimetidine, administered as a primed continuous infusion using a 300-mg bolus followed by 37.5 mg/h, was compared with sucralfate, administered via nasogastric tube, at a dosage of 1 g every 6 hours suspended in 20 mL of sterile water.
End points of the study included nosocomial pneumonia, gastrointestinal hemorrhage, and death.
Fifty-six patients were randomized to receive cimetidine and their rate of pneumonia was 12.5%; upper gastrointestinal hemorrhage, 3.6%; and mortality, 33.9%. Fifty-eight patients were given sucralfate, and their rate of pneumonia was 13.8%; upper gastrointestinal hemorrhage, 3.4%; and mortality, 37.9%. There were no significant differences between these study end points. In patients who had pneumonia, 80% of isolates were aerobic gram-negative bacilli.
These observations suggest that the rate of nosocomial pneumonia is not increased in patients in the intensive care unit who receive prophylaxis with cimetidine to prevent stress ulcer bleeding.
近期研究对组胺(H2)受体拮抗剂用于应激性溃疡预防提出质疑,因其会增加医院获得性肺炎及随后死亡的发生率。
这项前瞻性随机研究比较了西咪替丁与硫糖铝的预防效果。
马萨诸塞州斯普林菲尔德的内科/外科重症监护病房。
纳入114例患者。
将西咪替丁以首剂负荷量300mg静脉推注,随后以37.5mg/h持续输注的方式给药,与通过鼻胃管给予硫糖铝进行比较,硫糖铝剂量为每6小时1g,溶于20mL无菌水中。
研究终点包括医院获得性肺炎、胃肠道出血和死亡。
56例患者随机接受西咪替丁治疗,其肺炎发生率为12.5%;上消化道出血发生率为3.6%;死亡率为33.9%。58例患者给予硫糖铝治疗,其肺炎发生率为13.8%;上消化道出血发生率为3.4%;死亡率为37.9%。这些研究终点之间无显著差异。在发生肺炎的患者中,80%的分离菌为需氧革兰氏阴性杆菌。
这些观察结果表明,在重症监护病房接受西咪替丁预防应激性溃疡出血的患者中,医院获得性肺炎的发生率并未增加。
