This study evaluated coma scales for drug overdose patients. The Reaction Level Scale (RLS) demonstrated the highest reliability for assessing responsiveness in poisoned patients.

Area of Science:

  • Neurology
  • Toxicology
  • Clinical Assessment

Background:

  • Accurate assessment of neurological function is critical in patients with acute drug overdose.
  • Existing coma scales may require validation for specific patient populations, such as those with toxicological ingestions.
  • Standardized and reliable assessment tools are needed to guide clinical management.

Purpose of the Study:

  • To evaluate the reliability and validity of three coma scales in patients with acute drug overdose.
  • To compare the effectiveness of different painful stimulation techniques for assessing responsiveness.
  • To determine the most suitable coma scale for the neurological evaluation of poisoned patients.

Main Methods:

  • The study included 26 patients diagnosed with acute drug overdose.

  • Three coma scales were assessed for reliability and validity.
  • Six painful stimulation techniques were compared, including sternal rubbing and retromandibular pressure.
  • The Reaction Level Scale (RLS) was identified as the most reliable.

    • Main Results:

    • Sternal rubbing and retromandibular pressure were found to be the most effective painful stimulation techniques.
    • Improper application of stimulation techniques could lead to an underestimation of responsiveness in 4-19% of cases.
    • The Reaction Level Scale (RLS) exhibited the highest reliability among the evaluated scales.

    Conclusions:

    • The Reaction Level Scale (RLS) is a reliable tool for assessing comatose patients with drug overdose.
    • While potentially complex, the RLS and Glasgow Coma Scale are recommended if concomitant brain injury is suspected.
    • The Matthew-Lawson scale is confirmed as reliable for use in poisoned patients.
