Abstract:
We report a case of suspected liver dysfunction after general anesthesia with sevoflurane. A 30 day old male infant underwent inguinal herniorrhaphy under sevoflurane anesthesia (sevoflurane concentration: 1.3-1.5% with 50% oxygen and nitrous oxide). Two days after the operation, he developed frequent vomiting, anorexia and fever. GOT, GPT and LDH values were 242 Ku, 326 Ku and 901 Wu, respectively and peaked at 520 Ku, 709 Ku and 1000 Wu 12-16 days after the operation. Clinical symptoms and the laboratory data became normal within 2 months. The antibody titers of EB-virus, cytomegalo-virus and HA-virus were all within normal ranges and HBs antigen was negative. There were no blood transfusion or antibiotics administration before the onset, and no epidemic of hepatitis around him. His mother had no history of hepatitis during her pregnancy. Lymphocyte stimulation test for indication of sevoflurane allergy was also negative. From these evidences, toxic (not allergic) liver dysfunction due to exposure to sevoflurane was considered to be the most probable diagnosis.
Insights
This case study highlights potential toxic liver dysfunction in an infant following sevoflurane anesthesia. Elevated liver enzymes normalized within two months, suggesting a non-allergic, sevoflurane-induced hepatotoxicity.
Area of Science:
- Anesthesiology
- Pediatric Hepatology
- Toxicology
Background:
- Sevoflurane is a widely used inhalational anesthetic in pediatric surgery.
- Liver dysfunction is a rare but serious complication associated with general anesthesia.
- Distinguishing between allergic and toxic reactions to anesthetic agents is crucial for patient management.
Observation:
- A 30-day-old male infant developed symptoms of liver dysfunction, including vomiting and anorexia, two days post-inguinal herniorrhaphy under sevoflurane anesthesia.
- Significant elevations in liver enzymes (GOT, GPT, LDH) were observed, peaking 12-16 days after surgery.
- Viral hepatitis markers, blood transfusions, and antibiotic use were ruled out as causes.
Findings:
- The infant's clinical symptoms and laboratory values indicating liver dysfunction gradually resolved within two months.
- A lymphocyte stimulation test for sevoflurane allergy was negative.
- The pattern of liver enzyme elevation and clinical course suggested a toxic, rather than allergic, reaction to sevoflurane.
Implications:
- This case suggests that sevoflurane can cause direct toxic liver injury in infants, independent of an allergic mechanism.
- Further investigation into the mechanisms of sevoflurane-induced hepatotoxicity is warranted.
- Clinicians should consider sevoflurane toxicity in the differential diagnosis of unexplained liver dysfunction in pediatric patients post-anesthesia.
