This study, done out of Australia, examined the association between abdominal pain and severity of liver injury in patients presenting after acute acetaminophen overdose.
539 cases were identified where N-acetylcysteine was administered to patients with acetaminophen overdose. The investigators explored parameters including presence of abdominal pain, time post-ingestion, and peak ALT.
Patients less than 8 hours post overdose WITH abdominal pain were as likely to develop hepatotoxicity as those presenting WITHOUT abdominal pain. (OR=1.18 [0.07 to 19.4])
Patients presenting 8 or more hours post overdose WITH abdominal pain were as likely to develop hepatotoxicity as those WITHOUT abdominal pain (OR=1.28 [0.39 to 4.21])
Don't let lack of pain fool you! Just as we all learned in medical school - let your history be your guide!
