Anesthetic Considerations for Patients on Renal Replacement Therapy

Area of Science:

• Nephrology
• Cardiology
• Anesthesiology

Background:

• Increasing prevalence of patients with renal dysfunction requiring renal replacement therapy (RRT) due to aging population and improved therapies.
• Renal dysfunction and RRT significantly impact all perioperative phases, including associated comorbidities and altered physiology.
• Elevated risk of perioperative cardiac morbidity and mortality is a critical concern in this patient group.

Purpose of the Study:

• To highlight the challenges in managing patients with renal dysfunction undergoing surgery.
• To underscore the increased cardiac risks associated with renal dysfunction and RRT in the perioperative setting.
• To identify the need for definitive guidelines for perioperative optimization and management.

Main Methods:

• Review of current literature on perioperative management of patients with renal dysfunction and RRT.
• Analysis of risk factors for cardiac morbidity and mortality in this population.
• Identification of gaps in existing perioperative care guidelines.

Main Results:

• Patients requiring RRT exhibit a significantly higher risk of perioperative cardiac complications.
• Altered physiology and comorbidities associated with renal dysfunction complicate anesthetic and surgical management.
• Lack of established, evidence-based guidelines complicates risk mitigation strategies.

Conclusions:

• Perioperative management of patients with renal dysfunction and RRT presents unique and significant challenges.
• Urgent development of clear guidelines is needed to optimize care and reduce adverse cardiac outcomes.
• Further research is essential to establish best practices for this growing patient population.
