Predosing Chemical Stability of Admixtures of Propofol, Ketamine, Fentanyl, and Remifentanil

Anesth Analg. 2019 Jul;129(1):e13-e15. doi: 10.1213/ANE.0000000000003772.

Abstract

Admixtures of propofol-ketamine, propofol-ketamine-fentanyl, and propofol-ketamine-remifentanil were subjected to various clinically relevant conditions to study their chemical stability. A novel high-performance liquid chromatography-mass spectrometry method revealed no degradation of any compound by incubation at 37°C, constant mixing, or table-top storage for 6- and 24-hour time periods, except variable recovery of both propofol and fentanyl in the admixtures of propofol-ketamine-fentanyl suggesting possible degradation.
