๐ฉบ Peritoneal Dialysis (PD) โ SIMPLE SUMMARY
๐น What PD is - PD is a way to clean the blood using the belly - The peritoneum (belly lining) works as a filter - Special fluid goes in โ pulls waste & water โ comes out ๐ No machine filtering blood directly. ๐น How PD works (easy) 1. Fluid goes into the belly ๐ซ 2. Waste + extra water move into the fluid ๐งช 3. Dirty fluid is drained ๐ฝ Glucose (sugar) in the fluid pulls water out. ๐น PD solution (whatโs inside) - ๐ก Glucose โ pulls fluid - โช Electrolytes (like blood) - โ NO potassium (so potassium leaves the body) - ๐ Buffer (usually lactate) ๐น Types of PD - CAPD โ manual, daytime exchanges - APD โ machine at night while sleeping ๐ โ ๏ธ Complications (important) ๐จ Peritonitis (BIG ONE) - Cloudy fluid โ๏ธ - Belly pain ๐ค - Fever ๐ก๏ธ ๐ Cloudy drainage = emergency โก Seizures โ can PD cause them? ๐ Not directly Seizures happen because of: - Low sodium ๐งโฌ๏ธ (MOST common) - Low calcium - Uremia (toxins) - High glucose from PD fluid ๐ Always think: electrolyte problem โ Why PD is UNCOMMON - Patient must be clean & responsible - High infection risk - Needs daily work by patient - Not good for: Poor hygiene Cognitive problems Hernias Prior abdominal surgery ๐ Many patients canโt manage it safely โ
Why choose PD instead of Hemodialysis (HD) PD advantages - ๐ฉธ More stable blood pressure - โค๏ธ Better for the heart - ๐ Done at home - ๐ No needles or fistula - ๐ง Preserves kidney function longer - ๐ฝ๏ธ Less strict diet Choose PD if patient: - Is stable - Has heart failure - Has poor vascular access - Wants independence - Can follow instructions Choose HD if patient: - Is unstable - Poor hygiene - Canโt self-care - Repeated infections ๐ง ONE-LINE MEMORY (EXAM GOLD) Peritoneal dialysis cleans blood using fluid in the abdomen and is chosen for stable patients who want home dialysis with fewer blood pressure changes.
