Flashcards
IV anesthesia
IV anesthesia
A type of anesthesia administered intravenously, commonly used for induction due to its rapid and smooth onset.
Thiopental Sodium
Thiopental Sodium
A barbiturate used for anesthesia, known for its fast onset of coma within 30 seconds and long half-life.
Ketamine
Ketamine
An anesthetic agent that increases blood pressure and heart rate, making it suitable for shocked patients, and is also a bronchodilator ideal for asthma patients.
Propofol

Study Notes
IV Anesthesia Overview
- IV anesthetics are commonly used for induction due to rapid onset.
- Inhalational anesthetics are typically used for maintenance, allowing minute-by-minute control.
- Consciousness returns during IV anesthesia due to drug redistribution from brain to blood/tissue.
Thiopental Sodium
- Yellowish powder with a bitter taste and faint garlic smell.
- Induces coma within 30 seconds of administration.
- Long half-life, unsuitable for prolonged use due to potential accumulation and barbiturate coma.
- Used to treat status epilepticus because of its potent anticonvulsant properties.
Ketamine
- A potent analgesic.
- Unique anesthetic that elevates blood pressure and heart rate, useful for shocked patients.
- Causes salivation, needing anticholinergic premedication.
- Commonly used in pediatric anesthesia.
- Acts as a bronchodilator, suitable for status asthmaticus patients.
Propofol
- Rapid onset and recovery with minimal side effects.
- Preferred for day-care procedures like breast biopsies.
- A potent cardiopulmonary depressant, potentially leading to more frequent and prolonged apnea.
Complications of IV Anesthetics
Intra-arterial Injection
- Can cause crystal formation in capillaries.
- Treatment: 5 ml procaine (local anesthetic) and 40 ml papaverine (vasodilator).
Perivenous Injection/Extravasation
- Occurs when IV line breaks, releasing drug into surrounding tissue.
- Symptoms: Blanching, pain, tissue necrosis.
- Treatment: Hyaluronidase (breaks down the drug).
