Summary
Posterior reversible encephalopathy syndrome (PRES) is a rare neurological condition. Anesthesiologists must recognize PRES in patients with delayed emergence from anesthesia to prevent severe disability.
Area of Science:
- Neurology
- Anesthesiology
- Radiology
Background:
- Posterior reversible encephalopathy syndrome (PRES) is a rare neurological and radiological condition.
- PRES typically presents with neurological symptoms and characteristic white matter edema, often reversible with prompt management.
- While associated with hypertension and renal issues, PRES can occur in diverse clinical settings, with limited reports in anesthesiology.
Observation:
- A 46-year-old male developed delayed emergence and post-operative blindness after elective ophthalmic surgery under general anesthesia.
- These symptoms were attributed to the intraoperative onset of Posterior Reversible Encephalopathy Syndrome (PRES).
Findings:
- This case highlights PRES as a potential complication during the perioperative period.
- Delayed recognition and management of PRES can lead to severe, long-term neurological deficits.
Implications:
- Anesthesiologists should maintain a high index of suspicion for PRES in patients with delayed emergence from anesthesia.
- Prompt diagnosis via MRI is crucial for effective management and prevention of permanent neurological damage.

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

104
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
