In a healthy adult undergoing an uncomplicated craniotomy, when is discharge typically expected and what are the criteria and postoperative management recommendations?

Expected Discharge After Craniotomy

For healthy adults undergoing uncomplicated craniotomy for tumor resection, same-day discharge is feasible and safe in carefully selected patients, with a 90.6% success rate and low readmission rates. 1

Discharge Timing Based on Procedure Type

Same-Day Discharge (Elective Tumor Craniotomy)

• Same-day discharge can be achieved in approximately 88-91% of appropriately selected patients undergoing craniotomy for supratentorial tumor resection 2, 1
• Success rates are higher with awake craniotomy compared to general anesthesia, though both approaches are viable 1
• Readmission within 24 hours occurs in only 1-2% of same-day discharge patients 2, 1

Extended ICU Stay (Decompressive Craniectomy)

• All patients undergoing decompressive craniectomy for stroke require ICU admission immediately postoperatively, with typical ICU stays of several days 3
• A substantial proportion require tracheostomy and gastrostomy for initial postoperative management 4, 3
• These patients face prolonged recovery with monitoring for wound dehiscence, hydrocephalus development, and need for ventriculoperitoneal shunt placement 3

Criteria for Same-Day Discharge

Patient Selection Factors (Predictive of Successful Early Discharge)

• Good preoperative functional status with high Karnofsky Performance Scale scores and low modified Rankin Scale scores 5
• Male gender and younger age are independent predictors 5
• Low modified frailty index score (frailty negatively predicts early discharge) 5
• Absence of significant comorbidities (patients with ≥2 comorbidities have higher readmission rates) 6

Surgical Factors Favoring Early Discharge

• Supratentorial location (not infratentorial/posterior fossa) 5, 1
• Right-sided lesions 5
• Smaller tumor size 5
• Awake craniotomy technique 5, 1
• Absence of cerebrospinal fluid drain placement 5

Mandatory Discharge Criteria (Must Meet ALL)

• No new neurological deficits postoperatively 1
• No seizure activity 1
• Adequate pain control without excessive headache 1
• Controlled postoperative nausea and vomiting (PONV affects 47-50% of craniotomy patients and is a common cause of failed discharge) 3, 1
• Stable vital signs and neurological examination 1
• Appropriate social support at home 1

Postoperative Management Recommendations

Immediate Postoperative Monitoring

• Manage PONV with multimodal antiemetic regimen using medications that do not impair neurological examination (ondansetron plus dexamethasone are most effective) 7, 3
• Monitor for signs of intracranial hemorrhage, cerebral edema, or hydrocephalus as causes of altered mental status 3
• Distinguish expected postoperative sedation effects from pathologic causes 3

Complications Requiring Extended Stay

• New neurological deficit (most common reason for failed discharge, occurring in 28/59 failed discharges) 1
• Seizures (second most common reason) 1
• Uncontrolled PONV 1
• Excessive headache requiring IV analgesia 1
• Social factors preventing safe home discharge 1

Benefits of Early Discharge

Clinical Outcomes

• Lower rates of hospital-acquired complications including deep venous thrombosis/pulmonary embolism (4.4% vs 0% in POD1 discharge) 5
• Lower urinary tract infection rates (2.7% vs 0% in POD1 discharge) 5
• Decreased nosocomial infection risk overall 8, 5
• Lower 30-day readmission rates in early discharge patients (likely reflecting better baseline health) 5

Healthcare System Benefits

• Decreased hospital costs 8
• Fewer case cancellations 8
• High patient satisfaction 8

Common Pitfalls and Caveats

Critical Distinctions

• Do not apply same-day discharge protocols to decompressive craniectomy patients, who universally require ICU-level care 3
• High-volume centers (above 75th percentile for procedural volume) have lower 90-day readmission rates, suggesting institutional experience matters 6
• Insurance type affects readmission risk (Medicaid and Medicare patients have higher readmission rates than privately insured) 6

Optimization Strategies

• Implement Enhanced Recovery After Surgery (ERAS) protocols to facilitate safe early discharge 1
• Ensure multidisciplinary involvement (surgeons, anesthesiologists, nurses, allied health professionals) for program success 1
• Future optimization should focus on improved analgesia and PONV prevention to increase success rates 1

Contraindications to Early Discharge

• Infratentorial/posterior fossa procedures 5
• Placement of CSF drains 5
• Poor baseline functional status 5
• Significant frailty or multiple comorbidities 5, 6
• Lack of adequate home support 1
