Alcohol consumption, even at high blood alcohol concentrations (BAC), minimally impacts intraocular pressure (IOP) latency. However, BAC levels correlate with reduced body temperature and suggest pontomesodiencephal vulnerability, with brainstem auditory evoked potentials (BAEP) useful for diagnosing coma.

Area of Science:

  • Neuroscience
  • Toxicology
  • Ophthalmology

Context:

  • Investigating the acute effects of alcohol on physiological parameters.
  • Examining blood alcohol concentrations (BAC) ranging from 0.62% to 2.04%.

Purpose:

  • To assess the impact of acute alcohol intoxication on intraocular pressure (IOP) latency.
  • To explore correlations between BAC, body temperature, and brainstem function.
  • To evaluate the utility of brainstem auditory evoked potentials (BAEP) in diagnosing coma.

Summary:

  • Acute alcohol intoxication showed minimal prolongation in intraocular pressure (IOP) latency within standard deviations.
  • A significant correlation was observed between increased BAC and reduced body temperature.
  • Minor alterations in IOP latency suggest potential vulnerability in the pontomesodiencephal region.

  • Brainstem auditory evoked potentials (BAEP) demonstrated suitability for differentiating coma states of various origins.

    • Impact:

    • Highlights a potential neurophysiological vulnerability in the central nervous system under acute alcohol influence.
    • Establishes a link between alcohol intake, hypothermia, and central nervous system effects.
    • Validates BAEP as a diagnostic tool for assessing coma severity and origin.
