Summary
Severe intraoperative lactic acidosis during thoracoscopic surgery can be rare but serious. Thiamine administration successfully lowered lactate levels, suggesting thiamine deficiency as a potential contributing factor in this case.
Area of Science:
- Anesthesiology
- Critical Care Medicine
- Oncology
Background:
- Lactic acidosis is a common cause of metabolic acidosis in hospitalized patients.
- Severe intraoperative lactic acidosis (>8 mmol/L) during thoracoscopic surgery is rare, associated with poor prognosis.
- Elevated lactate typically improves with restored tissue perfusion.
