Description : Check out this medical titled "Managing Intoxication and Overdose" by Tonina Harvey.

This medical talks about Intoxication and Overdose and their management.

Intoxication and overdose are both conditions that occur when someone consumes too much of a substance, such as alcohol, drugs, or medication. Intoxication refers to the state of being under the influence of a substance, while overdose is when the amount of the substance consumed exceeds the bodys ability to process it.

Intoxication can be mild or severe depending on the amount and type of substance consumed. Mild intoxication may result in slurred speech, impaired judgment, and slower reaction times. Severe intoxication can lead to unconsciousness, respiratory depression, and even death.

Overdose occurs when the bodys ability to process a substance is overwhelmed, leading to toxic levels in the bloodstream. The symptoms of an overdose can vary depending on the substance, but may include nausea, vomiting, seizures, respiratory failure, and cardiac arrest.

Treatment for intoxication and overdose may involve supportive care such as oxygen therapy and monitoring of vital signs, as well as medication to manage symptoms and prevent further complications. In some cases, emergency medical attention may be necessary to prevent long-term damage or death.

It is important to seek medical attention immediately if you suspect someone has consumed too much of a substance, as prompt treatment can be lifesaving. Additionally, it is important to practice responsible substance use and avoid consuming more than the recommended amount of any substance.

Intoxication
Slide 5-

Other conditions can mimic intoxication Infection Respiratory disease, hypoxia Head injury (e.g. subdural haematoma) Acute psychosis Cerebrovascular accident (CVA or stroke) or transient ischaemic attack (TIA) Diabetes, hypo or hyper glycaemia Epilepsy, postictal confusion Drug toxicity (e.g. phenytoin, digoxin) Meningitis Alcohol and/or benzodiazepine withdrawal Wernicke’s encephalopathy
Slide 6-

Managing a Deteriorating Patient Attain accurate history, if possible Monitor Vital Signs: Temp Pulse BP Respiratory rate Oxygen saturation regularly as outlined by local policy Unconscious patients – ensure basic life support and that resuscitation equipment is readily available Escalate to Medical Officer if patient deteriorates or you have concerns
Slide 7-

A person who has had a potentially lethal overdose must be assessed immediately.
Slide 8-

General Principles for Management of Intoxication Treat any patient presenting as incoherent, disoriented or drowsy as having a head injury until proven otherwise Risk factors for accidental overdose include: history of overdose frequent use and higher levels of dependence use following period of abstinence (due to a reduced level of tolerance) mixing drugs / alcohol and regular poly substance use

Signs & Symptoms of Intoxication and Overdose
Slide 14-

Alcohol INTOXICATION Passing out or blackouts; stupor or coma; cold and clammy skin; lowered body temperature; lowered blood pressure; Slow and noisy respiration; accelerated heart rate or bradycardia; strong smell of alcohol; positive breath alcohol reading. OVERDOSE Alcohol intoxication is a potentially lethal condition. The majority of overdoses are due to polydrug toxicity involving the concomitant consumption of other CNS depressants Death is usually due to respiratory depression or inhalation of vomitus. Each person has a different tolerance to alcohol – on average, the lethal blood alcohol concentration is 0.45-0.5%.

Alcohol - Management
Slide 16-

Opioids Heroin / Morphine / Codeine / Oxycodone /Hydrocodone/ Fentanyl / Tramadol / Methadone INTOXICATION Reduced sensitivity to pain, euphoria or negative mood, dizziness or faintness. Decreased level of consciousness (from drowsiness to coma) slow respiration, bradycardia pinpoint' pupils muscle twitching cyanosis hypotension pulmonary oedema and hypothermia may also be present. OVERDOSE Aspiration pneumonia is the most serious condition frequently seen in heroin overdose. Opioids have emetic and cough suppressant properties, which, combined with a decreased level of consciousness can increase the likelihood of aspiration. Death is usually due to respiratory failure, although cardiac arrest may occur secondary to myocardial oxygen deprivation

Opioids - Management
Slide 18-

BenzodiazepinesDiazepam/ Alprazolam / Lorazepam/ Clonazepam/Flunitrazepam/Clobazam/ Nitrazepam / TemazepamZolpidem / Zopiclone - known as Z Drugs INTOXICATION Benzodiazepines have anxiolytic, sedative, hypnotic, muscle relaxant and anti-epileptic effects. Unwanted effects include: depression confusion feelings of isolation or euphoria impaired thinking and memory loss headache, drowsiness, sleepiness and fatigue, dry mouth, slurred speech or stuttering double or blurred vision impaired coordination dizziness and tremors nausea and loss of appetite diarrhoea or constipation OVERDOSE CNS depression (over-sedation or sleep) is the most common finding after overdose. Respiratory depression may also occur, but is more common with concurrent use with alcohol, opioids In high doses, patients may manifest coma, respiratory depression, hypotension, bradycardia, hypothermia, and rhabdomyolysis.

Benzodiazepines - Management
Slide 20-

Psychostimulants“Ritalin” / “Concerta” / Dexamphetamine/ Lis dexamphetamine / Cocaine / Amphetamine/ Methamphetamine and MDMA “Ecstasy” INTOXICATION Euphoria, increased sense of wellbeing, increased energy, more confidence or over-confidence, improved cognitive and psychomotor performance, suppression of appetite and reduced sleep. OVERDOSE Increased heart rate and respiration, nausea and vomiting, dilated pupils, hot and cold flushes, sweating, headaches, pallor, jaw clenching, paranoia, anxiousness, panic attacks, difficulty sleeping, moodiness, irritability and agitation. Secondary complications can involve the kidneys, skeletal muscles and gastrointestinal system. The most common causes of death related to amphetamine toxicity are arrhythmia, hyperthermia and intracerebral haemorrhage.

Psychostimulants -Management
Slide 22-

HallucinogensLysergic acid diethylamide (LSD) / phencyclidine (PCP, Angel dust)/psilocybin (magic mushrooms) and dimethyl tryptamine (DMT). INTOXICATION Euphoria and wellbeing, dilation of pupils, seeing and hearing things that aren’t there (hallucinations), confusion and trouble concentrating, depersonalisation, derealisation, headaches, nausea, fast or irregular heartbeat, increased body temperature, breathing quickly, vomiting, facial flushes, sweating and chills. Psychiatric disturbances such as prolonged psychosis, depression, personality disruption and post-hallucinogen perceptual disorder have been attributed to prolonged use. OVERDOSE Many patients intoxicated with hallucinogens are awake, aware that their symptoms are drug-induced, and able to provide a history of recreational hallucinogen use. Seizure and rhabdomyolysis have been reported in extreme cases. Severe injury or death (e.g. from drowning) more commonly occur as a result of impaired judgment and warped sense of distance, time and reality while intoxicated.
Slide 23-

Hallucinogens -Management Uncomplicated intoxication may only require observation and supportive care Monitoring in a quiet environment until symptoms subside. Symptoms of intoxications are self-limited and not usually severe a conservative approach is preferred unless there is evidence of severe toxicity (e.g. hyperthermia and severe agitation). Benzodiazepines are first-line therapy for acute agitation and dysphoria. If psychotic symptoms persist (e.g. after agitation subsides), neuroleptics such as haloperidol may be titrated with careful monitoring.

CannabisHerbal Cannabis ( Marijuana) / Cannabis resin( Hashish) / Cannabis oil (Hashish oil) / Cannabis products - Nabiximols INTOXICATION Complications associated with inhalation of cannabis include acute exacerbations and poor symptom control in patients with: asthma; chest pain, subcutaneous emphysemas caused by deep inhalation with breath holding and rarely, angina and myocardial infarction. OVERDOSE Signs of cannabis intoxication in adolescents and adults may include: tachycardia; increased blood pressure or orthostatic hypotension increased respiratory rate conjunctival injection (red eye) dry mouth increased appetite Nystagmus ataxia and slurred speech.
Slide 25-

Cannabis -Management Recreational cannabis intake to achieve psychoactive effects can often result in adverse effects because there is no clear indication of doses that achieve symptoms desired by the user and noxious effects. Monitoring vital signs Asymptomatic treatment as effects of cannabis also vary between people and may even be different for the same person at different times.

Reflection Questions What are the illnesses or injuries that can mimic intoxication? What is the key principle for managing anyone who is disorientated, drowsy or confused? How would you recognize if a patient was progressing from intoxication to overdose? What are the core elements of care when providing support to an intoxicated person? What are your local protocols for management of intoxication & overdose? Where might you locate these?
