Insights
Propofol-related infusion syndrome (PRIS) can cause severe metabolic acidosis and hemodynamic instability in critically ill patients. This review examines PRIS presentation, mechanisms, and management strategies.
Area of Science:
- Critical Care Medicine
- Pharmacology
- Pediatric Intensive Care
Background:
- Continuous propofol infusion is widely used for sedation and anesthesia in critically ill patients.
- Propofol-related infusion syndrome (PRIS) has been increasingly reported in both adult and pediatric populations.
- PRIS is associated with severe metabolic acidosis, hemodynamic instability, and arrhythmias.
Purpose of the Study:
- To review the existing literature on propofol-related infusion syndrome (PRIS).
- To describe the clinical presentation, proposed mechanisms, and potential management of PRIS.
- To address the ongoing debate regarding propofol's role in PRIS development.
Main Methods:
- Comprehensive literature search for studies reporting on PRIS.
- Analysis of clinical characteristics, patient demographics, and outcomes.
- Review of proposed pathophysiological mechanisms and treatment strategies.
Main Results:
- PRIS is characterized by metabolic acidosis, hemodynamic instability, and bradyarrhythmias, often refractory to treatment.
- The syndrome can occur with or without hepatomegaly, rhabdomyolysis, or lipemia.
- At least 20 deaths in pediatric patients have been attributed to PRIS.
Conclusions:
- PRIS is a serious complication of continuous propofol infusion in critically ill patients.
- Understanding the clinical features and mechanisms is crucial for timely diagnosis and management.
- Further research is needed to elucidate the exact relationship between propofol and PRIS and to develop effective preventative strategies.
Abstract:
Over the past two decades numerous reports have described the development of a propofol-related infusion syndrome (PRIS) in critically ill adult and pediatric patients who received continuous infusion propofol for anesthesia or sedation. The syndrome is generally characterized by progressive metabolic acidosis, hemodynamic instability and bradyarrhythmias that are refractory to aggressive pharmacological treatments. PRIS may occur with or without the presence of hepatomegaly, rhabdomyolysis or lipemia. To date, the medical literature contains accounts of 20 deaths in critically ill pediatric patients who developed features consistent with PRIS. These reports have generated considerable discussion and debate regarding the relationship, if any, between propofol and a constellation of clinical symptoms and features that have been attributed to its use in critically ill pediatric patients. This paper reviews the literature concerning PRIS, its clinical presentation, proposed mechanisms for the syndrome, and potential management should the syndrome occur.
