What are the complications of gastric lavage?

Complications of gastric lavage include aspiration pneumonia, charcoal aspiration, laryngospasm, inadvertent tracheal intubation, and respiratory insufficiency [11,12]. Placement of the tube can increase vagal tone and may cause a life-threatening bradydysrhythmia.

What is universal antidote?

Purpose of review For decades, activated charcoal has been used as a ‘universal antidote’ for the majority of poisons because of its ability to prevent the absorption of most toxic agents from the gastrointestinal tract and enhance the elimination of some agents already absorbed.

What are the indications for gastric lavage?

Gastric lavage is indicated for the ingestion of potentially life-threatening substances, such as cyanide, calcium-channel blockers, colchicine, chloroquine, and tricyclic antidepressants. It should never be used in patients with nontoxic ingestions.

Why gastric lavage is rarely performed in patients with toxic ingestion?

In human patients, gastric lavage is not recommended in the routine treatment of poisoned patients because of the lack of evidence that it improves clinical outcome and because of the potential for increased morbidity.

Is gastric lavage done in OP poisoning?

Gastric decontamination should only be done after the patient has been stabilised and treated with oxygen, atropine, and an oxime. Gastric lavage is the most common form of decontamination for organophosphorus poisoning despite the absence of randomised controlled trials to confirm benefit.

What are indications and contraindications for the stomach lavage?

Contraindications to gastric lavage include the following: Ingestion of caustic substances (risk of esophageal perforation) Uncontrolled convulsions, because of the danger of aspiration and injury during the procedure. Ingestion of low-viscosity petroleum distillate products.

What do current researches say about gastric lavage as a management option in poisoning?

We are told that gastric lavage should not be used unless two criteria are met: it should be used within an hour of ingestion of the poison, and the amount of toxin should be substantial. Though these criteria are repeated often in the literature there is no evidence to support either of them.

What will be the first step in treatment of poisoning?

Wipe any vomit away from their mouth and keep their head pointing down, to allow any vomit to escape without them breathing it in or swallowing it. Do not give them anything to eat or drink. If the person is not breathing or their heart has stopped, begin CPR (cardiopulmonary resuscitation) if you know how to.

Can activated charcoal be used in organophosphate poisoning?

As with other types of overdose, activated charcoal fails to make a difference.

When is gastric lavage indicated?

Gastric lavage must be performed soon after ingestion to be at all effective in removing drugs from the stomach. For this reason, many clinicians do not lavage patients who have overdosed if more than 1 hour has elapsed since ingestion. Gastric lavage may result in major morbidity (e.g., esophageal perforation).

What are the 3 types of poison?

In regard to poisoning, chemicals can be divided into three broad groups: agricultural and industrial chemicals, drugs and health care products, and biological poisons—i.e., plant and animal sources.

What is a universal antidote?

What is the antidote of organophosphate?

The definitive treatment for organophosphate poisoning is atropine, which competes with acetylcholine at the muscarinic receptors.

Why is atropine used for organophosphate poisoning?

Atropine is administered intravenously to restore adequate cardiorespiratory function rapidly – a process often termed ‘atropinzation’. It is used to reverse bradycardia and improve systolic blood pressure to greater than 80 mmHg.

What do current researchers say about gastric lavage as a management option in poisoning?

Extensive review of the literature for evidence of effectiveness concluded in 2004 that “Gastric lavage should not be employed routinely, if ever, in the management of poisoned patients” and that “The results of clinical outcome studies in overdose patients are weighed heavily on the side of showing a lack of …

Which medicine is best for poison?

activated charcoal – sometimes used to treat someone who’s been poisoned; the charcoal binds to the poison and stops it being further absorbed into the blood. antidotes – these are substances that either prevent the poison from working or reverse its effects. sedatives – may be given if the person is agitated.
