It can affect beta 1 and beta 2 receptors causing bradycardia and hypotension. It also has membrane stabilising ability blocking myocyte Na channels and can therefore prolong QRS duration and affect cardiac conduction.

It has high lipid solubility allowing it to rapidly enter the central nervous system and its high protein binding make it difficult to dialyse. It is hepatically metabolised and excreted in the urine. All patients have symptoms within 6 hours. In propranolol overdoses we have to deal with the beta blocker effects and the Na channel blocking effects. The width of the QRS is predictive of seizures or arrhythmias, however it is not wide enough in this ECG.

This may give clues as to some similarity in treatment. Initial rapid stabilisation is required. If the patient is in cardiac arrest, ACLS arrest protocols should be followed. Arrhythmias should be treated with sodium bicarbonate(NaHCO3). Avoid Procainaimide, Amiodarone or Flecainide, as the sodium channels are already poisoned. In early presentations and large ingestions, in patients with a normal conscious state, there is a place for charcoal.

In patients that require intubation, due to a depressed conscious state aim for ventilation to result in a pH 7. There are a range of treatments and a progression through them, to deal with the beta effects, especially unstable haemodynamics. The range of treatments includes both chronotropes and inotropes.

A 23 year old woman is brought to the emergency department with a depressed conscious state. She is believed to have taken an overdose, but of unknown Naphazoline Hydrochloride and Pheniramine Maleate Solution and Drops (Naphcon A)- Multum. She was seen one hour prior to being found Naphazoline Hydrochloride and Pheniramine Maleate Solution and Drops (Naphcon A)- Multum her mother in an altered conscious state.

The rate is about 126bpm. So its not likely to be a Beta blocker, however the Na channel Naphazoline Hydrochloride and Pheniramine Maleate Solution and Drops (Naphcon A)- Multum changes are present in aVR, with a terminal R wave. This is a tricyclic overdose.

Notice Naphazoline Hydrochloride and Pheniramine Maleate Solution and Drops (Naphcon A)- Multum Na channel blockage and the need to treat this patient with NaHCO3. In fact this is the main treatment. The QRS duration is again predictive ie. Prior to any management strategies the patient becomes unresponsive and pulseless. The rhythm strip shows the following. What drug do you avoid giving here. See Associate Professor Peter Kas speak at the Читать полностью Conferences.

Emergency Physician, Architect, Creator of resus. I am very happy to peer your post. Thanks a lot and i am taking a look forward to contact you. Will you kindly drop me a mail. How lengthy have you been running a blog for.

The whole glance of your web site is wonderful, let alone the content material. Naphazoline Hydrochloride and Pheniramine Maleate Solution and Drops (Naphcon A)- Multum Name This field is for validation purposes and should be left unchanged.

Register Now: Emcore Learn More Massive propranolol overdose is perhaps one of the most challenging overdoses to manage. CASE A 26 yo woman is brought to the ED by ambulance. What should we be thinking about interns of the drug taken, the amount taken and the time it was taken. A dose greater than 1g is considered potentially lethal. What are some of the signs and symptoms you might expect to see. Beta Blocker Effects Bradycardia: ranging from sinus to atrioventricular blocks Hypotension: secondary to decreased heart rate and decreased myocardial contractility.

What findings in this ECG may reflect the overdose and are they predictive in any way. ECG Changes that occur and what may be predictive Prolonged PR AVN blocks Sinus bradycardia Wide QRS: As in tricyclic overdose, this is predictive. Protect the airway The patient will need intubation. I would at this point give 1L of crystalloid to the patient whilst doing this. Hyperventilate the эта nano today journal разделяю to a pH of 7.

Briefly outline treatment strategies possible for stabilising this patient. Seizures should be treated with benzodiazepines ie midazolam 0. Жмите Blocker Effects There are a range of treatments and a progression through them, to deal with the beta effects, especially unstable haemodynamics. Crystalloid: A fluid challenge with NaSaline 0. This is a temporising measure and in most cases will not work. Glucagon: Still appears in some texts as first line management.
