Observational Study
Peripheral venous and arterial lactate agreement in septic patients in the Emergency Department: a pilot study.
Lactate measurements are routinely used in sepsis for prognostication and for guiding treatment. Although venous lactate measurements have widely been used, most studies have used arterial lactate (A-LACT). The interchangeability between the measurements is debatable. ⋯ The mean difference between the measurements (venous-arterial) was 0.54 mmol/l, with 95% limits of agreement of -0.11 to 1.18 mmol/l. This pilot study demonstrates the potential use of PV-LACT as a substitute for A-LACT measurement in septic ED patients. However, further definitive investigation is needed to support widespread clinical adoption of peripheral venous lactate.
