پروپوفول

Propofol is a powerful anesthetic agent commonly used in medical settings to induce and maintain sedation and anesthesia. It is a clear, colorless liquid that is administered intravenously. Propofol is known for its rapid onset and short duration of action, making it a preferred choice for various surgical and diagnostic procedures. It?s called 'milk of anesthesia' because its lipid emulsion gives it a milky look, which is a result of its lipid emulsion formulation.

Uses of Propofol

• Induction and Maintenance of Anesthesia: It is widely used in surgeries to help patients remain unconscious and pain-free.
• آرام بخش برای رویه ها: Propofol is often used for sedation during procedures like endoscopy or dental surgery.
• Intensive Care Unit (ICU) Sedation: It is used to sedate patients who require mechanical ventilation or are undergoing critical care.
• وضعیت صرع: Propofol may be used in refractory (treatment-resistant) cases under close supervision in intensive care by neurology or anesthesiology specialists.

How Does Propofol Work

Propofol works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter in the brain that inhibits nerve activity. By increasing GABA's effects, Propofol helps to calm the brain and induce a state of sedation or unconsciousness. This mechanism allows for quick recovery after the medication is stopped, making it ideal for outpatient procedures.

مقدار و نحوه مصرف

بزرگسالان:

The typical dosage for induction of anesthesia is 1.5?2.5 mg/kg administered intravenously (IV). For maintenance, a continuous infusion of 4?12 mg/kg/hour may be used.

کودکان:

For children, the induction dose is usually 2-3 mg/kg, and maintenance can be adjusted based on the child's response and procedure.

Propofol is administered via intravenous injection or continuous infusion. It is not available in tablet form.

Propofol must only be administered by trained healthcare professionals in a monitored setting due to risks like respiratory depression and low blood pressure (hypotension). Vital signs are closely watched during and after use.
