Markers of Liver Apoptosis After Anesthesia With Sevoflurane or Propofol

2014-08-27 03:18:27 | BioPortfolio

Summary

Anesthesia may affect the function of vital organs. Liver is one of them. The investigators hypothesis is that intravenous or inhalation anesthesia does not impair liver function as assessed by more elegant tests like markers indicating liver apoptosis. In the present randomized prospective trial female patients scheduled for mastectomy or thyroidectomy will receive inhalation or total intravenous anesthesia and markers for liver dysfunction will be determined.

Description

Female patients undergoing mastectomy or thyroidectomy under sevoflurane or propofol anesthesia will be recruited for the study. The type of anesthesia will be determined in a random way using a computer generated table.

All patients will be preoxygenated for 3 minutes before induction of anesthesia. Patients assigned to the sevoflurane group will receive an inhalation induction with sevoflurane via a primed anesthetic circle system and anesthesia will be maintained with sevoflurane. In the propofol group patients anaesthesia will be induced and maintained with propofol.

Blood samples for liver apoptotic markers will be collected before induction of anesthesia, after skin closure as well as 24 and 48 hours postoperatively.

Blood samples will be centrifuged, stored at -80 degrees Celsius and analyzed for M30 and M60 values with radioimmunoassay technique. SGPT and SGOT levels will also be determined.

Medical and Biotech [MESH] Definitions

An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes. (From Smith and Reynard, Textbook of Pharmacology, 1992, 1st ed, p206). Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.

Rare and often fatal drug complication which affects patients undergoing long-term treatment with high doses of PROPOFOL. It is characterized by METABOLIC ACIDOSIS; HYPERLIPIDEMIA; RHABDOMYOLYSIS; cardiovascular CIRCULATORY COLLAPSE; CARDIAC FAILURE; and KIDNEY FAILURE.

A conserved class of proteins that control APOPTOSIS in both VERTEBRATES and INVERTEBRATES. IAP proteins interact with and inhibit CASPASES, and they function as ANTI-APOPTOTIC PROTEINS. The protein class is defined by an approximately 80-amino acid motif called the baculoviral inhibitor of apoptosis repeat.

Tumor necrosis factor receptor family members that are widely expressed and play a role in regulation of peripheral immune responses and APOPTOSIS. The receptors are specific for TNF-RELATED APOPTOSIS-INDUCING LIGAND and signal via conserved death domains that associate with specific TNF RECEPTOR-ASSOCIATED FACTORS in the CYTOPLASM.

A transmembrane-protein belonging to the TNF family of intercellular signaling proteins. It is a widely expressed ligand that activates APOPTOSIS by binding to TNF-RELATED APOPTOSIS-INDUCING LIGAND RECEPTORS. The membrane-bound form of the protein can be cleaved by specific CYSTEINE ENDOPEPTIDASES to form a soluble ligand form.
