Propofol is a versatile drug that functions as both an anesthetic and sedative. It is typically administered intravenously and is effective in both the induction and maintenance stages of anesthesia. In intensive care units, propofol often replaces benzodiazepines for extended sedation. The drug's effects vary depending on the dosage, but it has a short duration of action.
A notable characteristic of propofol is its ability to decrease intracranial pressure and cerebral oxygen consumption. It also possesses anti-convulsant properties. These features make it a favorable choice for patients with head injuries. Both children and adults have specific guidelines for using propofol, including appropriate dosages.
Exceeding the recommended dosage of the drug can cause hypotension, apnea, and cardiac arrhythmias. 'Propofol infusion syndrome' or PRIS is the term used to describe when two or more
...adverse effects occur. Although PRIS is rare, it can be fatal if not promptly detected. Many healthcare providers are unaware of this potential consequence of propofol. Nurses taking care of patients receiving propofol infusion must be alert and observant in recognizing these signs early on.
It is vital to continuously monitor electrocardiography, saturations, and blood pressure for early detection of this fatal condition. In addition, nurses need to have a comprehensive understanding of proper dosages, accurate infusion mixing techniques, and precise delivery rates to prevent overdosing. The administration of propofol should not exceed 50 ug/kg/min for reducing intracranial pressures and should be limited to a maximum duration of 48 hours. Regular monitoring of laboratory values and pH levels is crucial as well. Clinical indications of adverse reactions to propofol include cardiovascular collapse, metabolic acidosis, rhabdomyolysis, hyperlipemia, an
hypertriglyceridemia.
