T48.1X2

Clinical Causes: Intentional overdose as an act of self-harm or suicide attempt Misuse or abuse of neuromuscular blocking agents for non-medical purposes Accidental ingestion, although less common, especially in settings where these drugs are accessible Lack of proper storage and control of medications containing skeletal muscle relaxants

Key Symptoms: Muscle paralysis progressing from the extremities inward Difficulty breathing or respiratory failure due to paralysis of respiratory muscles Weakness or loss of muscle strength Loss of consciousness in severe cases Hypotension or low blood pressure Bradycardia or irregular heartbeat Possible complete paralysis leading to loss of consciousness and coma

Diagnosis Path: Reviewing the patient’s medical history and any known or suspected ingestion of neuromuscular blocking agents Physical examination focusing on muscle strength and airway patency Blood tests to identify the presence of the drug or its metabolites Monitoring respiratory function and neurological status Electromyography (EMG) studies to evaluate muscle activity, if necessary

Treatment Protocols: Secure airway and ensure adequate ventilation, often requiring mechanical ventilation in severe cases Administration of specific antidotes is generally not available for neuromuscular blocking agents; treatment is primarily supportive Use of medications like cholinesterase inhibitors may be considered in some cases to reverse certain types of paralysis, but their effectiveness varies Continuous monitoring of vital signs and respiratory function Detoxification procedures such as activated charcoal may be administered if the ingestion was recent Supportive care for cardiovascular stability, including fluids and medications as needed Psychological or psychiatric intervention following medical stabilization, especially in cases of intentional self-harm
