Accuracy of pH strip testing and pH liquid testing versus standard pH meter of gastric contents in critically ill patients: a diagnostic accuracy study.

ABSTRACT:

Objective

The utilisation of pH level measurements from gastric contents may indicate the preferred tip position of a nasogastric tube or monitor the efficacy of stress ulcer prophylaxis in critically ill patients. We aimed to determine the accuracy of pH strip (pHS) tests and pH liquid (pHL) tests compared with the standard pH meter (pHM).

Design

Diagnostic accuracy study.

Setting

Gastric contents from medically critically ill patients.

Participants

In total, 113 gastric samples were collected from 27 critically ill patients.

Outcome measure

The level of pH measured by pHM, pHS and pHL.

Results

The pH values measured by pHM, pHS and pHL were 5.83 (IQR 5.12-6.61), 5.50 (IQR 5.00-6.00) and 5.75 (IQR 5.25-6.25), respectively. The pHS test showed gre
