Post‑operative Recovery Timeline After Open Appendectomy in an Indian Tertiary Care Setting

As a consultant surgeon with over two decades of experience in tertiary hospitals across India, I have witnessed the nuanced recovery patterns that patients exhibit after an open appendectomy. While the procedure itself is considered a routine abdominal operation, its postoperative course can vary significantly based on patient factors (age, comorbidities), intra‑operative findings (perforation, abscess), and institutional protocols. This article outlines a detailed, day‑by‑day recovery timeline, integrating evidence‑based medicine with the practical realities of Indian healthcare. It also lists the typical medications, laboratory investigations, and key milestones that a surgeon, anesthesiologist, nursing team, and patient’s family should monitor to ensure optimal outcomes.

Pre‑operative Baseline (Day –1 to Day 0)

• Baseline investigations: CBC with differential, ESR/CRP, serum electrolytes, renal function tests (BUN/Creatinine), liver enzymes (SGOT/SGPT), coagulation profile (INR/PTT), blood group & cross‑match. In patients >60 yrs or with diabetes, an HbA1c is also checked.
• Imaging: Routine abdominal ultrasound; CT abdomen with contrast is reserved for complicated cases (perforation, abscess).
• Pre‑operative antibiotics: Cefuroxime 1 g IV + metronidazole 500 mg IV, administered within 60 min of incision.
• Consent & education: Discuss risks (bleeding, infection, ileus), benefits, and postoperative care plans. Provide a written booklet in the patient’s preferred language.

Intra‑operative Phase (Day 0)

• Procedure: Classical open appendectomy via a 6–8 cm mid‑line or right lower quadrant incision. In cases of perforation, peritoneal lavage with 1 L warm saline and placement of a closed suction drain if necessary.
• Anesthesia: General anesthesia with a balanced technique (sevoflurane + opioid). In high‑risk patients, regional block (e.g., caudal epidural) may be added for analgesia.
• Intra‑operative monitoring: ECG, NIBP, pulse oximetry, capnography. Keep the patient warm with active warming devices to reduce hypothermia.

Immediate Post‑operative Period (Day 0 – Day 1)

• ICU/Recovery: Most patients are shifted to the ward after 2–3 h of recovery. Vital signs recorded every 15 min for the first hour, then hourly.
• Analgesia: Intravenous morphine 2 mg q4h PRN (max 10 mg/day) + paracetamol 1 g q6h PRN. For patients with renal impairment, switch to tramadol 50 mg q8h.
• Antibiotics: Continue cefuroxime 1 g IV q8h + metronidazole 500 mg IV q8h for 48 h. If intra‑operative contamination was significant, extend to 5–7 days.
• Early mobilization: Ambulate with assistance after 6 h of surgery to prevent venous thromboembolism (VTE). Apply graduated compression stockings.
• Diet: Clear liquids 6 h post‑op. Transition to semi‑solid diet by Day 1 if bowel sounds are present.
• Laboratory monitoring: CBC 6 h post‑op to assess for occult bleeding. CRP and ESR on Day 2 to gauge inflammatory response.

Day 1 – Day 3: Early Recovery

• Wound care: Inspect incision for erythema, drainage, or dehiscence. Clean with sterile saline; apply a non‑adhesive dressing.
• Analgesia transition: Shift to oral analgesics (tramadol 50 mg q6h PRN + paracetamol 1 g q8h). Add NSAIDs (ibuprofen 400 mg q6h) if no contraindication.
• Antibiotic regimen: Switch to oral amoxicillin‑clavulanate 625 mg q8h for a total of 5–7 days, depending on intra‑operative contamination.
• Diet progression: Advance to regular diet by Day 2 if bowel sounds are normal. Encourage high‑fiber foods to prevent constipation.
• Mobility: Walk 20–30 min twice daily. Encourage deep breathing exercises and incentive spirometry to prevent atelectasis.
• Lab checks: CBC, electrolytes, CRP on Day 2. If CRP >10 mg/dL or WBC >15,000/µL, investigate for infection.

Day 3 – Day 7: Intermediate Recovery

• Wound assessment: Incision should be clean, with minimal erythema. If drainage persists >48 h, consider culture and adjust antibiotics.
• Analgesia: Taper opioids; maintain NSAIDs and paracetamol. If pain persists >3 /10, evaluate for neuropathic component (gabapentin 300 mg q12h PRN).
• Antibiotics: Discontinue if no signs of infection and CRP trending down. If abscess suspected, obtain CT scan.
• Diet: Full diet; monitor stool frequency. Administer lactulose 10 mL orally if constipation.
• Mobility & rehabilitation: Introduce light resistance exercises (leg lifts, ankle pumps). Continue ambulation 30–45 min thrice daily.
• Lab monitoring: CBC, electrolytes on Day 5. ESR on Day 7 to confirm inflammatory resolution.

Day 7 – Day 14: Late Recovery & Discharge Planning

• Discharge criteria:
1. No fever >38 °C for 24 h.
2. WBC <10,000/µL and CRP <5 mg/dL.
3. Normal incision healing (no drainage, mild erythema only).
4. Patient tolerates regular diet and ambulates independently.
• Discharge medications:
1. Oral analgesic: tramadol 50 mg q6h PRN.
2. Antibiotic: amoxicillin‑clavulanate 625 mg q8h for remaining days if indicated.
3. Prophylactic anticoagulant: low‑molecular‑weight heparin (enoxaparin) 40 mg SC daily for 7 days if VTE risk high.
4. Prokinetic: metoclopramide 10 mg q8h PRN for delayed gastric emptying.
• Follow‑up: 7–10 days post‑op for wound inspection, CBC, ESR. If any abnormality persists, repeat imaging.

Potential Complications & Early Detection

• Infection (superficial or deep): Monitor for erythema, warmth, purulent drainage. Use wound cultures to guide antibiotics.
• Abscess formation: Persistent fever >48 h, localized abdominal pain. CT abdomen with contrast is diagnostic.
• Intestinal obstruction (post‑operative ileus): Abdominal distension, vomiting. Manage conservatively with nasogastric decompression and fluid resuscitation.
• Bleeding: Drop in hemoglobin >2 g/dL, tachycardia. Re‑explore if hemodynamic instability.
• Venous thromboembolism: Swelling, pain in lower limbs. Doppler ultrasound if suspected.

Success Rates & Outcomes in India

The overall success rate for open appendectomy in Indian tertiary hospitals exceeds 95 %. Mortality is <0.5 % when performed electively and <2 % in perforated cases. The average length of stay is 4–5 days for uncomplicated cases and extends to 7–10 days for complicated presentations.

Key Take‑away Points

• Early mobilization and adequate analgesia are critical for preventing complications.
• Antibiotic stewardship: tailor duration based on intra‑operative findings and inflammatory markers.
• Patient education: empower families with signs of infection and when to seek immediate care.
• Follow‑up: ensure wound inspection and laboratory monitoring to detect late complications.

Adhering to this structured timeline, coupled with vigilant monitoring for complications, ensures that patients undergoing open appendectomy in India experience safe and efficient recovery.
