Discharge Criteria: Vitals First - The Stability Check
- Core Vital Signs: Stable & within acceptable limits. 📌 (BP, HR, RR, SpO2, Temp)
- Blood Pressure (BP): Near baseline (e.g., within ±20% of pre-op).
- Heart Rate (HR): 50-120 bpm (stable, patient-dependent).
- Respiratory Rate (RR): 10-24 breaths/min, unlabored.
- SpO2: ≥92-94% on room air (or patient's baseline).
- Temperature: Afebrile (e.g., 36.0°C - 37.5°C).
- Pain Control: Adequately controlled (e.g., VAS ≤ 3-4/10).
- PONV Management: Minimal; no active vomiting in last 30 min.
- Surgical Site Assessment: No active/excessive bleeding or swelling.
⭐ Vital signs should be stable and recorded for at least 30 minutes (often two consecutive sets of readings) prior to discharge from PACU Phase I.

Discharge Criteria: Patient Factors - Awake & Able
- Mobility & Ambulation:
- Patient can ambulate safely, consistent with their pre-procedure baseline.
- Oral Intake:
- Tolerates oral fluids without experiencing significant nausea or vomiting.
- Voiding (Procedure-Dependent):
- Has voided spontaneously, especially important after spinal/epidural anesthesia or relevant surgeries (e.g., urologic, pelvic).
- Cognitive Function:
- Fully oriented (time, place, person).
- Able to understand and retain discharge instructions; judgment is unimpaired.
- Respiratory Status:
- No signs of respiratory depression; maintains stable respiratory rate and oxygen saturation (SpO2).
⭐ Post-Ambulatory Discharge Scoring Systems (PADSS) are commonly used; a score of ≥9 often indicates readiness for discharge.
Discharge Criteria: Scoring & Send-off - The Go/No‑Go
- Scoring for Readiness:
- Modified Aldrete Score: Assesses recovery post-anesthesia.
- 📌 ALDRETE: Activity, Respiration, Circulation, Consciousness, O2 Saturation.
- Threshold for PACU Phase II transfer/readiness: Score ≥9 (out of 10).
- PADSS (Post Anesthetic Discharge Scoring System): Key for home discharge.
- Evaluates: Vital signs, Activity (ambulation), Nausea/Vomiting, Pain, Surgical Bleeding.
- Home readiness: Score ≥9 (out of 10).
- Modified Aldrete Score: Assesses recovery post-anesthesia.
- Final Checks (Go/No-Go):
- Responsible adult escort confirmed.
- Written & verbal discharge instructions given (incl. emergency contact info).
- Pain controlled with oral analgesia.
- Minimal nausea & vomiting.
⭐ Patient must be able to tolerate oral fluids and void (if applicable, e.g., post-spinal or urologic surgery) before discharge, in addition to achieving target PADSS score.
High‑Yield Points - ⚡ Biggest Takeaways
- PADSS (Post Anesthetic Discharge Scoring System) is a key discharge assessment tool.
- Stable vital signs (near baseline) are mandatory.
- Patient must be alert, oriented, or at preoperative mental status.
- Pain and PONV (Postoperative Nausea and Vomiting) must be controlled.
- Ability to ambulate (if appropriate) and tolerate oral fluids is crucial.
- A responsible adult escort and clear discharge instructions are essential.
- Voiding may be required post-spinal or urological procedures.
