Depolarizing Blockers: Pharmocokinetics01:19

Depolarizing Blockers: Pharmocokinetics

723
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions

1.2K
Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.
Although all competitive neuromuscular blockers are designed...

Depolarizing Blockers: Mechanism of Action01:28

Depolarizing Blockers: Mechanism of Action

3.5K
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because...

General Anesthesia: Overview01:24

General Anesthesia: Overview

1.0K
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

997
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Antiarrhythmic Drugs: Class I Agents as Sodium Channel Blockers

4.2K
Class I antiarrhythmic drugs are used to treat various types of arrhythmias or irregular heart rhythms. These drugs block the sodium (Na+) channels in the cardiac cells, thereby affecting the movement of electrical impulses across the heart. Class I antiarrhythmic drugs are divided into three subgroups: Class IA, Class IB, and Class IC, each with distinct mechanisms of action and effects on the heart.
Class 1A Antiarrhythmic Drugs: These drugs work by moderately blocking sodium channels,...

Summary

A healthy military member with undiagnosed congenital complete heart block experienced a cardiac emergency during anesthesia for a routine surgery. This case underscores the critical need for thorough preoperative screening for heart conditions.

Area of Science:

  • Cardiology
  • Anesthesiology
  • Military Medicine

Background:

  • Congenital complete heart block is a rare condition affecting heart rhythm.
  • Active duty military personnel undergo regular health assessments.
  • Septorhinoplasty is a common surgical procedure.

Purpose of the Study:

  • To report a case of anesthetic complication in a patient with undiagnosed congenital complete heart block.
  • To emphasize the importance of comprehensive preoperative evaluation.
  • To highlight anesthetic risks in patients with congenital heart rhythm disease.

Main Methods:

  • Case report of a 25-year-old female active duty military member.
  • Review of the perioperative anesthetic management.
  • Analysis of the patient's cardiac event during anesthesia induction.

Main Results:

  • The patient presented for septorhinoplasty with a history of congenital complete heart block, which was not disclosed preoperatively.
  • During anesthesia induction, she developed severe bradycardia and near asystole, requiring resuscitation.
  • The electrocardiogram was unavailable prior to the event.

Conclusions:

  • Undiagnosed congenital heart rhythm disease poses significant anesthetic risks.
  • Thorough preoperative screening, including electrocardiogram review, is crucial for identifying at-risk patients.
  • Prompt recognition and management are vital for adverse cardiac events during anesthesia.
