Hospital Stay After Appendectomy: Standard vs. Dialysis Patients

Length of stay (LOS) after appendectomy depends on surgical approach, complications, and comorbidities.

Uncomplicated Appendicitis (Laparoscopic)

• Typical LOS: Same-day discharge to 1 night (Enhanced Recovery After Surgery/ERAS protocols).
• Traditional: 1–2 nights.
• Criteria: tolerating PO, pain controlled on oral meds, afebrile, ambulating, voiding.

Complicated Appendicitis (Perforation, Abscess, Peritonitis)

• LOS: 3–7+ days.
• IV antibiotics, possible drains, delayed oral intake, higher complication rate (abscess, ileus, SSI).

Patients on Dialysis (ESRD)

• Baseline Risks: Uremic platelet dysfunction (bleeding), accelerated atherosclerosis, infection susceptibility, volume overload, electrolyte shifts.
• Perioperative Dialysis: Schedule pre-op (day before or morning) to optimize volume/electrolytes; post-op next scheduled session. Avoid heparin if bleeding risk.
• Antibiotic Dosing: Renal-adjusted (e.g., cefazolin, metronidazole, gentamicin levels).
• Analgesia: Avoid NSAIDs; use acetaminophen, cautious opioids, gabapentin (renal dose).
• Expected LOS: +1–3 days vs. non-ESRD for uncomplicated; longer if complicated. Close nephrology/surgery coordination essential.
• Access Protection: Preserve fistula/graft; avoid subclavian lines.

Discharge Criteria (All Patients)

• Oral intake, pain control, bowel function, afebrile, independent ambulation, follow-up arranged.

Individualized planning with anesthesiology, nephrology, and surgery optimizes outcomes for dialysis patients.
