This is important because many drugs can cause an anion-gap metabolic acidosis (see Table 2), which can lead to further instability. This may not happen if there has been any head injury , aspiration or any other organ damage. Coma can result from therapeutic drugs as well as recreational drugs and drug abuse. Coma may be due to direct toxic effect of drugs on the brain or indirect effect due to disturbances of other systems. Young males appear to be particularly susceptible to developing neuroleptic malignant syndrome, and other predisposing factors include dehydration, preexisting cognitive dysfunction, and high doses of higher potency neuroleptics (eg, haloperidol), especially when given as an intramuscular injection.

Drug overdoses can be accidental or intentional. The pupils are typically small but reactive and dilate widely in response to a narcotic antagonist (eg, naloxone). The first of these to appear are often headache, fatigue, nausea, and concentration difficulties. Distribution of benzodiazepines in the brain and their enhancement of GABA activity at specific sites accounts for the clinical features of benzodiazepine-induced coma to a large extent. A case of fulminant hepatitis after administration of abiraterone acetate [Article in Japanese]. Endocrine disorders may alter the mental state, including hypothyroidism and hypocortisolemia. Without the oxygen and sugars it needs to function, the brain is unable to deliver the electrical signals needed to maintain breathing and organ function. What Else Makes Rapid Detox a Risky Gamble?

Handling drug overdoses in the hospital setting - Today's Hospitalist Other syndromes such as serotonin syndrome, neuroleptic malignant syndrome, and propofol infusion syndrome that may be characterized by drug-induced coma are not discussed in detail. Dexmedetomidine is notable for its ability to provide sedation without risk of respiratory depression (unlike other commonly used sedatives such as propofol, fentanyl, and midazolam) and can provide cooperative or semi-arousable sedation.Similar to clonidine, it is an agonist of alpha 2 -adrenergic receptors in certain parts of the brain.

Neuroleptic malignant syndrome manifests as high fever, severe muscle rigidity, and autonomic dysfunction. Response by recovery after intravenous glucose indicates hypoglycemic coma, response to naloxone usually indicates opiate drug overdose, and response to flumazenil indicates benzodiazepine overdose. In most instances, hypoxia improves with mask oxygen ventilation only, but noninvasive positive-pressure ventilation (NIPPV) and endotracheal intubation may be required. Other considerations include vitamin B12 and niacin deficiency. 3525 Del Mar Heights Rd, Ste 304San Diego, CA 92130-2122.

A coma can result from the direct toxic effect of drugs on the brain or indirect effect due to disturbances of other systems, an article in the journal Neurology MedLink explained. After 3 weeks of comatose state. Complete blood count, blood chemistry, liver function studies, ammonia level, and an arterial blood gas. Endozepines, the ligands for benzodiazepine recognition sites on GABAA receptors in the CNS, are elevated. Let's take a deeper look into this. Drug-induced coma should be differentiated from coma due to structural lesions of the brain and metabolic encephalopathies. Lacroix C, Kheloufi F, Montastruc F, Bennis Y, Pizzoglio V, Micallef J.

Several drugs, therapeutic as well as recreational, can produce a comatose state, either as a desired effect of their administration (eg, anesthetic medications) or due to inappropriate administration, overdose, toxic side effects, or idiopathic reaction. What is the survival rate of someone in a coma after an overdose? Acetaminophen level is often not included in standard toxicology screens, but if this drug is suspected based on the history, it should be specifically requested. Pulmonary edema. This may occur secondary to herniation from mass effect, acute hydrocephalus with blockage of the ventricular system, or as an effect of a remote tumor, such as with a paraneoplastic syndrome. Patients are often hyporeflexive and, with larger doses, brainstem or cranial nerve dysfunction can occur. This resembles barbiturate coma, but pupils are often unequal and nonreactive. Severe hallucinations, seizures, and cardiac rhythm disturbances can occur. For example, benzodiazepines and opiates commonly cause respiratory suppression; amphetamines and cocaine cause hypertension, tachydysrhythmias, and myocardial infarction; and tricyclic antidepressants (TCA) may cause conduction block. On a positive note, he is no longer abusing drugs or alcohol. Ethanol alcohol use is commonly complicated by combined overdose with other recreational drugs. Patients develop a decreased level of consciousness and sometimes become comatose. Intubation and hyperventilation may aid in this process. Clinical manifestations of methanol ingestion include optic neuropathy, abdominal pain, and impairment of consciousness, which may result in coma. The patient made a full recovery with normalization of laboratory values. Low serum carnitine levels may predispose patients to impairment of consciousness when treated with valproic acid. The Rhabdomyolysis was a direct result of the muscle damage from laying on a hard surface for hours. Education in schools, by public awareness campaigns, and by parents is instrumental in decreasing illicit drug use in teenagers and young adults.
