Determination of succinylcholine in tissues by TLC, GC/NPD, and GC/MS
Journal of Analytical Toxicology
|September 1, 1983
Summary
Succinylcholine is difficult to detect due to rapid breakdown in blood. However, this study shows that analyzing animal tissues can reveal unchanged succinylcholine using chromatography.
Area of Science:
- Pharmacology
- Analytical Chemistry
- Toxicology
Background:
- Succinylcholine is rapidly hydrolyzed by plasma pseudocholinesterase, making it an elusive analyte.
- Tissue acetylcholinesterase exhibits limited activity against succinylcholine, suggesting potential for detection in tissues.
Purpose of the Study:
- To describe and validate chromatographic techniques for analyzing succinylcholine in human tissues.
- To overcome the analytical challenges posed by succinylcholine's rapid hydrolysis.
Main Methods:
- Thin-layer chromatography (TLC)
- Gas chromatography with nitrogen-phosphorus detection (GC/NPD)
- Gas chromatography-mass spectrometry (GC/MS)
- Validation using tissues from succinylcholine-treated rats.
Main Results:
- Demonstrated the applicability of TLC, GC/NPD, and GC/MS for succinylcholine analysis in tissues.
- Successfully validated these chromatographic methods using animal models.
Conclusions:
- Chromatographic analysis of tissues offers a viable approach to detect unchanged succinylcholine.
- These methods provide a means to analyze succinylcholine in human tissues, overcoming plasma stability issues.
