Key advantages include suitability for home use, flexible scheduling, and reduced cardiovascular burden. Limitations include strict sterile technique requirements to prevent peritonitis and potential long-term loss of intraperitoneal proteins and glucose fluctuations. Indicated for patients with residual renal function (>5%), those wishing to maintain work/study flexibility, and those without significant abdominal surgical history or severe pulmonary disease.

In anesthesia practice, ensuring airway patency and normal respiratory function is of vital importance.
