TLDR
Plasma propofol levels by head space-gas chromatography analysis using solid-phase microextraction saves time, and does not require elimination of interfering substances in the plasma.Abstract:
IMPLICATIONS We measured plasma propofol levels by head space-gas chromatography analysis using solid-phase microextraction. This method saves time, and does not require elimination of interfering substances in the plasma. The coefficient variation was +/-5% to +/-30%. The detection limit was 10 ng/mL.read more

Assessment of propofol concentrations in human breath and blood by means of HS-SPME–GC–MS
TL;DR: Reliable and precise analytical methods such as HS-SPME-GC-MS represent basic requirements if breath analysis is to be set up for non-invasive monitoring of intravenous drugs and control of anesthesia.
Patent
System and method for monitoring health using exhaled breath
TL;DR: In this paper, the authors present a system and methods for monitoring endogenous compound concentration in blood by detecting markers, such as odors, upon exhalation by a patient, wherein such markers are either endogenous compound itself or result from the endogenous compound.
Patent
Method and apparatus for monitoring respiratory gases during anesthesia
TL;DR: In this paper, a method and system is provided for monitoring delivery of anesthesia (inhalational and intravenous) and detecting the depth of anesthesia wherein at least one anesthetic agent is absorbed in patient's bloodstream during the administration of anesthesia.
Patent
Method and apparatus for monitoring intravenous (iv) drug concentration using exhaled breath
TL;DR: In this article, a method and system for detecting the depth of anesthesia wherein at least one anesthetic agent is absorbed in a patient's bloodstream during the administration of anesthesia, which includes sampling the patient's expired breath, analyzing the breath for concentration of at least 1 substance indicative of the anesthetic agents, and determining the effect of the agent based on that concentration.

Pharmacokinetics of propofol (diprivan) in elderly patients
TL;DR: The pharmacokinetics of propofol (2,6 diisopropylphenol) were compared in patients aged 65-80 yr and 12 patients aged 18-35 yr and showed no trend with time after dose.

Propofol concentration monitoring in plasma or whole blood by gas chromatography and high-performance liquid chromatography.
TL;DR: Monitoring of propofol concentrations by the methods of GC and HPLC gives equivalent results, but plasma samples are preferred, but immediate centrifugation is needed.
