suspected/confirmed cocaine toxicity: non-body packer/stuffer
observation and monitoring
All patients should be monitored in the accident and emergency department, including cardiac monitoring. Chest pain should prompt obtaining a high-sensitivity cardiac troponin level. If myocardial injury is present or suspected, see Non-ST-elevation myocardial infarction or ST-elevation myocardial infarction. Note that the safety of beta-blockers in life-threatening cocaine-related cardiovascular toxicity is controversial, with studies showing both benefit and harm.[23]Lavonas EJ, Akpunonu PD, Arens AM, et al. 2023 American Heart Association focused update on the management of patients with cardiac arrest or life-threatening toxicity due to poisoning: an update to the American Heart Association guidelines for cardiopulmonary resuscitation and emergency cardiovascular care.

sedative
Treatment recommended for ALL patients in selected patient group
Benzodiazepines are the drugs of choice for the management of agitation.[25]Webb A, Angus D C, Finfer S, et al. Oxford textbook of critical care. 2nd ed. Oxford: Oxford University Press; 2016.[37]Lott C, Truhlář A, Alfonzo A, et al. European Resuscitation Council guidelines 2021: cardiac arrest in special circumstances. Resuscitation. 2021 Apr;161:152-219. https://www.resuscitationjournal.com/article/S0300-9572(21)00064-2/fulltext http://www.ncbi.nlm.nih.gov/pubmed/33773826?tool=bestpractice.com If a patient's condition requires rapid sedation and benzodiazepines are not effective (e.g., extreme hyperthermia or dangerous behaviour), an antipsychotic may be given.
Sedation (with a benzodiazepine or an antipsychotic) of an agitated patient may make it easier to perform any necessary investigations and reduces the likelihood of hyperthermia. The principal adverse effect of benzodiazepines is oversedation. This can usually be avoided by judiciously titrating the dose to the patient's symptoms. In the most severe cases of oversedation airway protection may be temporarily necessary.
Antipsychotics (e.g., haloperidol, ziprasidone) are usually second-line because they may cause ECG changes, anticholinergic effects, or proconvulsant effects.[38]Stroup TS, Gray N. Management of common adverse effects of antipsychotic medications. World Psychiatry. 2018 Oct;17(3):341-56. https://pmc.ncbi.nlm.nih.gov/articles/PMC6127750 http://www.ncbi.nlm.nih.gov/pubmed/30192094?tool=bestpractice.com
Ketamine may be considered if rapid sedation is necessary for patient safety, but the potential for laryngospasm and emergence reactions limit its routine use.[39]Cole JB, Moore JC, Nystrom PC, et al. A prospective study of ketamine versus haloperidol for severe prehospital agitation. Clin Toxicol (Phila). 2016 Aug;54(7):556-62. http://www.ncbi.nlm.nih.gov/pubmed/27102743?tool=bestpractice.com

isotonic saline
Treatment recommended for ALL patients in selected patient group
Correct volume depletion with intravenous isotonic saline.
external cooling and sedation
Treatment recommended for ALL patients in selected patient group
Hyperthermia is the most common cause of death associated with cocaine toxicity.
Significant hyperthermia should be treated similarly to heat stroke; promptly with sedation and external cooling.[24]Zimmerman JL. Cocaine intoxication. Crit Care Clin. 2012 Oct;28(4):517-26. http://www.ncbi.nlm.nih.gov/pubmed/22998988?tool=bestpractice.com Cocaine-associated psychomotor agitation with intense physical activity can be approached in a similar way to exertional heat illnesses. The National Athletic Trainers' Association defines a threshold of >40.5°C (>105°F) for increased morbidity and mortality which increase with the length of time body temperature remains above this threshold.[46]Casa DJ, DeMartini JK, Bergeron MF, et al. National Athletic Trainers' Association position statement: exertional heat illnesses. J Athl Train. 2015 Sep;50(9):986-1000. https://meridian.allenpress.com/jat/article/50/9/986/112280/National-Athletic-Trainers-Association-Position http://www.ncbi.nlm.nih.gov/pubmed/26381473?tool=bestpractice.com Ice water immersion produces more rapid cooling than evaporative methods.[47]Armstrong LE, Crago AE, Adams R, et al.

Oxford textbook of critical care. 2nd ed. Oxford: Oxford University Press; 2016. If temperature is >40.5°C (>105°F), external cooling, sedation, and paralysis should be performed regardless of other clinical features.[46]Casa DJ, DeMartini JK, Bergeron MF, et al.

Paralysis should be only performed in conjunction with mechanical ventilation.[49]Catravas JD, Waters IW. Acute cocaine intoxication in the conscious dog: studies on the mechanism of lethality. J Pharmacol Exp Ther. 1981 May;217(2):350-6.
Paralysis should be maintained until life-threatening hyperthermia resolves.

vecuronium: consult specialist for guidance on dose
anti-arrhythmic therapy or defibrillation
Treatment recommended for ALL patients in selected patient group
Cardiac monitoring is indicated in all patients.
Ventricular fibrillation or non-perfusing (pulseless) ventricular tachycardia requires immediate defibrillation.
Wide complex tachycardias are managed with sodium bicarbonate, or lidocaine if sodium bicarbonate is ineffective.[42]Winecoff AP, Hariman RJ, Grawe JJ, et al. Reversal of the electrocardiographic effects of cocaine by lidocaine. Part 1: comparison with sodium bicarbonate and quinidine. Pharmacotherapy. 1994 Nov-Dec;14(6):698-703. http://www.ncbi.nlm.nih.gov/pubmed/7885973?tool=bestpractice.com [43]Parker RB, Perry GY, Horan LG, et al.

J Cardiovasc Pharmacol. 1999 Dec;34(6):864-9. http://www.ncbi.nlm.nih.gov/pubmed/10598131?tool=bestpractice.com
If administration of multiple doses of sodium bicarbonate is necessary, care should be taken to avoid hypernatraemia or volume overload.
Be aware that lidocaine can be proconvulsant.[45]Shih RD, Hollander JE, Burstein JL, et al. Clinical safety of lidocaine in patients with cocaine-associated myocardial infarction. Ann Emerg Med. 1995 Dec;26(6):702-6. http://www.ncbi.nlm.nih.gov/pubmed/7492040?tool=bestpractice.com
Primary options
sodium bicarbonate: 1 mEq/kg intravenous infusion
Secondary options
lidocaine: 1 to 1.5 mg/kg intravenous bolus over 2-3 minutes, followed by 1-4 mg/min intravenous infusion for 12-24 hours after rhythm control achieved
naloxone
Treatment recommended for ALL patients in selected patient group
When cocaine is taken in the presence of an opioid (such as a 'speedball'), the patient should be treated based on the prevailing toxidrome.
For example, if the respiratory rate is decreased and pupils are miotic (elements of the opioid toxidrome), naloxone should be titrated to adequate ventilation.[50]Nelson LS, Olsen D. Chapter 38: opioids. In: Hoffman RS, Nelson LS, Goldfrank LR, et al, eds. Goldfrank's toxicologic emergencies. 9th ed. New York, NY: McGraw-Hill; 2011. If ventilation does not improve following the administration of naloxone, diagnosis of opioid poisoning should be reconsidered.
If sympathomimetic symptoms predominate, benzodiazepines may be needed to control agitation and hyperthermia.
Primary options
naloxone: 0.04 to 2 mg intravenously every 2-3 minutes, maximum 10 mg/total dose
suspected/confirmed cocaine toxicity: body packer/stuffer
observation and monitoring
Patients should be observed until they have normal vital signs and mental status, unless there is potential for ongoing absorption of drug in which case the patients should be observed in a critical care setting until the packets have passed.
Even if body packers are asymptomatic, release of the drugs may be delayed so patients should be observed in accident and emergency department department for 8 hours from the time of suspected ingestion.[29]Royal College of Emergency Medicine. Management of suspected internal drug trafficker (SIDT). Dec 2020 [internet publication]. https://rcem.ac.uk/wp-content/uploads/2021/10/Management_of_Suspected_Internal_Drug_Trafficker_December_2020.pdf Asymptomatic body stuffers can be monitored for up to 6 hours.[24]Zimmerman JL.

bowel irrigation + activated charcoal + cardiac monitoring
Treatment recommended for ALL patients in selected patient group
Administer activated charcoal and perform whole-bowel irrigation to decontaminate the patient.[41]Smollin CG, Hoffman RS. Chapter 75: Cocaine. In: Nelson LS, Howland MA, Lewin NA, et al, eds. Goldfrank's toxicologic emergencies, 11th ed. New York, NY: McGraw-Hill Education; 2019. Although whole-bowel irrigation has not been rigorously evaluated, it may be helpful when used in the absence of contraindications; it should be considered to facilitate passage of the packets for body packers without evidence of bowel obstruction.[29]Royal College of Emergency Medicine. Management of suspected internal drug trafficker (SIDT).

isotonic saline
Treatment recommended for ALL patients in selected patient group

external cooling and sedation
Treatment recommended for ALL patients in selected patient group
Hyperthermia is the most common cause of death associated with cocaine toxicity.
Significant hyperthermia should be treated similarly to heat stroke; promptly with sedation and external cooling.[24]Zimmerman JL. Cocaine intoxication. Crit Care Clin. 2012 Oct;28(4):517-26. http://www.ncbi.nlm.nih.gov/pubmed/22998988?tool=bestpractice.com Cocaine-associated psychomotor agitation with intense physical activity can be approached in a similar way to exertional heat illnesses. The National Athletic Trainers' Association defines a threshold of >40.5°C (105°F) for increased morbidity and mortality which increase with the length of time body temperature remains above this threshold.[46]Casa DJ, DeMartini JK, Bergeron MF, et al.

Oxford textbook of critical care. 2nd ed. Oxford: Oxford University Press; 2016. If temperature is >40.5°C (>105°F), external cooling, sedation, and paralysis should be performed regardless of other clinical features.[47]Armstrong LE, Crago AE, Adams R, et al.

Am J Emerg Med. 1996 Jul;14(4):355-8. http://www.ncbi.nlm.nih.gov/pubmed/8768154?tool=bestpractice.com Paralysis should be only performed in conjunction with mechanical ventilation.[46]Casa DJ, DeMartini JK, Bergeron MF, et al.

vecuronium: consult specialist for guidance on dose
anti-arrhythmic therapy or defibrillation
Treatment recommended for ALL patients in selected patient group
Cardiac monitoring is indicated in all patients.
Ventricular fibrillation or non-perfusing (pulseless) ventricular tachycardia requires immediate defibrillation.
Wide complex tachycardias are managed with sodium bicarbonate, or lidocaine if sodium bicarbonate is ineffective.[42]Winecoff AP, Hariman RJ, Grawe JJ, et al. Reversal of the electrocardiographic effects of cocaine by lidocaine. Part 1: comparison with sodium bicarbonate and quinidine. Pharmacotherapy. 1994 Nov-Dec;14(6):698-703. http://www.ncbi.nlm.nih.gov/pubmed/7885973?tool=bestpractice.com [43]Parker RB, Perry GY, Horan LG, et al.

J Cardiovasc Pharmacol. 1999 Dec;34(6):864-9. http://www.ncbi.nlm.nih.gov/pubmed/10598131?tool=bestpractice.com
If administration of multiple doses of sodium bicarbonate is necessary, care should be taken to avoid hypernatraemia or volume overload.
Be aware that lidocaine can be proconvulsant.[45]Shih RD, Hollander JE, Burstein JL, et al. Clinical safety of lidocaine in patients with cocaine-associated myocardial infarction. Ann Emerg Med. 1995 Dec;26(6):702-6. http://www.ncbi.nlm.nih.gov/pubmed/7492040?tool=bestpractice.com
Primary options
sodium bicarbonate: 1 mEq/kg intravenous infusion
Secondary options
lidocaine: 1 to 1.5 mg/kg intravenous bolus over 2-3 minutes, followed by 1-4 mg/min intravenous infusion for 12-24 hours after rhythm control achieved
naloxone
Treatment recommended for ALL patients in selected patient group
When cocaine is taken in the presence of an opioid (such as a 'speedball'), the patient should be treated based on the prevailing toxidrome.
For example, if the respiratory rate is decreased and pupils are miotic (elements of the opioid toxidrome), naloxone should be titrated to adequate ventilation.[50]Nelson LS, Olsen D. Chapter 38: opioids. In: Hoffman RS, Nelson LS, Goldfrank LR, et al, eds. Goldfrank's toxicologic emergencies. 9th ed. New York, NY: McGraw-Hill; 2011. If ventilation does not improve following the administration of naloxone, diagnosis of opioid poisoning should be reconsidered.
If sympathomimetic symptoms predominate, benzodiazepines may be needed to control agitation and hyperthermia.
Primary options
naloxone: 0.04 to 2 mg intravenously every 2-3 minutes, maximum 10 mg/total dose
