![]() ![]() Both of these are considered as benchmark top models in their respective technologies. All samples were analyzed on the ABL555 blood gas analyzer and the Dade Dimension RxL Max, both located in the central laboratory. Blood samples were collected simultaneously for ABG and AA for electrolyte analysis. The study period started in August 2005 and ended in May 2006. Paired blood samples from 200 consecutive adult patients admitted to the Medical ICU of Apollo Hospitals were included in the study. The study was designed to be an observational study of a consecutive cohort of patients admitted to the ICU. The study was approved by the ethics committee of Apollo Hospitals, Hyderabad, India. ![]() The arterial blood gas (ABG) machines and AA differ in several aspects as listed in Table 1. Electrolytes are also measured during arterial blood gas analysis, but are traditionally rarely trusted for clinical decision-making because of the dearth of published research about the same. The operational cost of iSTAT and other similar equipment is a major deterrent to their utilization in developing systems of health care. Point-of-care testing for electrolytes is available from specialized equipment such as the iSTAT or Stat Profile Critical Care Xpress analyzers. Quick decisions that need to be made depending on electrolyte values hence are often made either blindly or are delayed. Typically, a turnaround time of about 15 min is noted on average in acute care laboratories of most tertiary care hospitals for the above. Routinely, all electrolytes are measured from serum by the auto-analyzers (AA) available in central laboratories of hospitals however, this is time-consuming. ![]() Įlectrolyte values are conventionally measured for all critical patients who present to the emergency department, for patients receiving fluid therapy, and for patients admitted to intensive care units (ICU). Point-of-care testing enables clinicians to initiate appropriate treatment for emergent conditions, thereby benefitting the patient both clinically and economically. ![]()
