Area of Science:

  • Hepatobiliary Surgery
  • Surgical Complications
  • Pharmacology

Background:

  • Partial right hepatic lobectomy is a surgical procedure for liver cancer.
  • Metastatic colon adenocarcinoma to the liver is a common indication for hepatic resection.
  • Post-operative care in the surgical intensive care unit is critical for patient monitoring.

Observation:

  • A patient developed severe hypotension, bradycardia, and asystole six hours post-partial right hepatic lobectomy.
  • Initial differential diagnoses included acute myocardial infarction, surgical site hemorrhage, and pulmonary embolism.
  • These common post-surgical complications were systematically ruled out.

Findings:

  • The patient's critical condition was not attributable to typical surgical complications.
  • An allergic reaction to vitamin K was identified as the probable cause of the adverse event.
  • Potential side effects and risks associated with vitamin K administration were discussed.

Implications:

  • Highlights the importance of considering rare drug reactions in post-operative care.
  • Suggests vigilance for adverse events following vitamin K administration in surgical patients.
  • Emphasizes the need for thorough differential diagnosis in critical post-operative scenarios.
