Regular evaluation of the pH of aspirated gastric juice is an important part of the routine prevention of the stress ulceration syndrome. This study has examined the use of commercially available pH paper for this purpose. Both clear buffer solutions and samples of gastric aspirate were used to assess the reliability of four products, Merck Universal pH Indicator strips (Art. 9535), Lyphan Universal pH Indicator paper, Whatman Wide Range pH paper and Macherey-Nagel Universal pH paper. The results show that the Merck strips and Lyphan paper are very reliable for measuring gastric aspirate pH and that intensive care nursing staff can make accurate observations when using these papers.
定期评估吸出胃液的pH值是应激性溃疡综合征常规预防的重要组成部分。本研究检验了为此目的使用市售pH试纸的情况。使用清澈缓冲溶液和胃吸出物样本评估了四种产品的可靠性，这四种产品分别是默克通用pH试纸（货号9535）、Lyphan通用pH试纸、Whatman宽范围pH试纸和Macherey-Nagel通用pH试纸。结果表明，默克试纸和Lyphan试纸在测量胃吸出物pH值方面非常可靠，重症监护护理人员在使用这些试纸时能够做出准确的观察。
