Overview
Cannabis intoxication delirium is a neuropsychiatric syndrome characterized by acute onset of altered mental status, often accompanied by perceptual disturbances, disorganized thinking, and altered consciousness in individuals under the influence of cannabis, particularly high doses of THC. 1Diagnosis
Clinical Presentation: Altered mental status, perceptual disturbances, disorganized thinking, and potential tachycardia 1.
Laboratory Tests: Blood THC levels to confirm recent cannabis use 1.
Electrocardiogram (ECG): Monitor for irregular heart rate patterns, noting higher frequency of tachycardia in THC-positive individuals 1.Management
Supportive Care: Ensure a safe environment, monitoring for vital signs, particularly heart rate irregularity 1.
Hydration and Monitoring: Maintain hydration and continuous monitoring for signs of worsening delirium or cardiovascular instability 1.
Pharmacological Interventions: No specific drug classes or doses mentioned for delirium management in cannabis intoxication 1.Special Populations
Elderly: Increased vulnerability to cardiovascular effects like irregular heart rate; closer monitoring advised 1.
Comorbidities: Presence of cardiovascular conditions may exacerbate tachycardia and irregular heart rhythms; tailored cardiovascular monitoring recommended 1.Key Recommendations
Conduct ECG monitoring in suspected cases of cannabis intoxication to assess for irregular heart rate patterns, particularly tachycardia 1 (Evidence: Moderate).
Confirm diagnosis with blood THC levels to identify recent cannabis use accurately 1 (Evidence: Strong).
Provide supportive care focusing on environmental safety and continuous vital sign monitoring, especially in elderly or those with cardiovascular comorbidities 1 (Evidence: Expert opinion).References
