Monitoring Parameters
Determine CV status prior to and during transurethral resection of the prostate (particularly in patients with cardiac disease). Monitoring of fluid and electrolyte levels may be considered.
Action
Description: Glycine is an amino acid and nonelectrolyte. Glycine 1.5% solution in water is nontoxic, nonhaemolytic and nonconductive with a refractive index near to that of water which makes it suitable as a urologic irrigating fluid during electrosurgical procedures. It is sufficient to minimise the risk of intravascular haemolysis that may occur from the absorption of plain water through open prostatic veins during transurethral resection.
Pharmacokinetics:
Metabolism: If systemically absorbed: Primarily metabolised via transamination to serine, and via deamination to ammonia which is usually converted to urea.
Excretion: Via the kidneys (if systemically absorbed).
