Summary
Postoperative cognitive dysfunction (POCD) is a complex issue following surgery. Future research should explore sleep, inflammation, pain, and environment
Area of Science:
- Anesthesiology
- Neuroscience
- Gerontology
Background:
- Postoperative cognitive dysfunction (POCD) is a significant concern after major surgery.
- The exact pathophysiology of POCD remains unclear, hindering diagnosis and treatment.
- Inconsistent methodologies and lack of standardized criteria complicate POCD research.
Purpose of the Study:
- To provide an updated review of POCD pathogenesis.
- To focus on perioperative factors influencing POCD.
- To explore the benefits of enhanced recovery after surgery (ERAS) using fast-track protocols.
Main Methods:
- Literature review and synthesis of current research on POCD.
- Analysis of perioperative pathophysiological mechanisms.
- Evaluation of fast-track recovery strategies.
Main Results:
- POCD pathogenesis is multifactorial, involving complex interactions.
- Key contributing factors include postoperative sleep disturbances, inflammatory responses, pain, and environmental influences.
- Enhanced recovery protocols may offer potential benefits in mitigating POCD.
Conclusions:
- Future research must investigate the roles of sleep, inflammation, pain, and environmental factors in POCD.
- Potential prophylactic interventions include minimally invasive surgery, multimodal non-opioid pain management, and modulation of inflammatory and sleep pathways.
