Plasma glucose concentrations during liver transplantation.

Area of Science:

• Transplantation Surgery
• Endocrinology
• Anesthesiology

Background:

• Orthotopic liver transplantation is a complex procedure with significant physiological demands.
• Intraoperative glucose metabolism can be altered during major surgical interventions.

Purpose of the Study:

• To investigate intraoperative plasma glucose concentrations in patients undergoing orthotopic liver transplantation.
• To identify patterns and potential causes of glucose level fluctuations during different phases of the procedure.

Main Methods:

• Retrospective review of intraoperative plasma glucose levels in 100 liver transplant recipients.
• Analysis of glucose concentrations during preanhepatic (Phase I), anhepatic (Phase II), and reperfusion (Phase III) phases.
• Correlation analysis between administered glucose from blood products and plasma glucose changes.

Main Results:

• Plasma glucose significantly increased from 110 +/- 46 mg/dl to 204 +/- 60 mg/dl during the preanhepatic phase (P < 0.05).
• No significant glucose changes occurred during the anhepatic phase.
• Plasma glucose significantly increased from 201 +/- 56 mg/dl to 384 +/- 72 mg/dl during reperfusion (P < 0.05).
• No correlation found between glucose in blood products and plasma glucose levels.
• No instances of hypoglycemia were observed; a trend towards hyperglycemia was noted in all patients.

Conclusions:

• Hyperglycemia is a consistent finding during orthotopic liver transplantation, particularly in the preanhepatic and reperfusion phases.
• The glucose in blood products does not appear to be the primary driver of intraoperative hyperglycemia.
• Close monitoring of glucose levels is essential during liver transplantation to manage potential hyperglycemia.
