Plain English Summary
Background and study aims
The area of the study is an emergency department, with patients presenting to emergency with acute/severe illnesses for example: chest pain (heart attacks), breathing difficulty (lung infections), stoppage of heart (cardiac arrest), brain strokes, poisoning are a few examples.
This study aims to determine whether a handheld arterial blood gas analyser (ABG), which produces results more quickly and is therefore beneficial to an emergency department, is as accurate as the central lab autoanalyzer at measuring sodium (Na+) and Potassium (K+) electrolytes.
Who can participate?
Adults aged above 18 years presenting to the emergency department
What does the study involve?
Eligible participants are treated as per the normal protocols of treatment, this study does not alter their treatment, routine care, hospital stay or outcome in terms of life or death of the participant, as it is just an observational study. Participants have blood samples taken and measured using a handheld arterial blood gas analyser and the central lab autoanalyzer.
What are the possible benefits and risks of participating?
There are no direct benefits or risks for participants in the study.
Where is the study run from?
NH Multispecialty Hospital (India)
When is the study starting and how long is it expected to run for?
April 2016 to November 2017

Study hypothesis
The null hypothesis states that there is no significant difference between electrolytes measured (sodium and potassium) using a handheld arterial blood gas analyzer (ABG) compared to the central lab autoanalyzer.

Intervention
This prospective observational study with a sample size of 200 study is conducted in NH-Multispecialty Hospital, Bangalore, India, in the emergency department. 200 consecutive patients with paired (2) samples of Arterial (1) and Venous (1) blood are included.
The study period is 1 year. The values of sodium (Na+) and potassium (K+) are measured using both a handheld arterial blood gas analyzer (ABG) and the central lab autoanalyzer, and compared using the paired t-test using R software. All results are expressed in mean +/- standard deviation.
