Post-Anesthesia Care Unit Operations

PACU Standards & Setup - Recovery HQ Setup

• Purpose: Immediate post-anesthesia observation, stabilization, management of complications.
• Location: Ideally near ORs; facilitates rapid transfer & staff access.
• Essential Setup:
  • Monitoring: ECG, NIBP, SpO₂, temperature; EtCO₂ (if indicated).
  • Airway: Oxygen, suction, intubation equipment.
  • Emergency: Defibrillator, code cart with drugs.
• Staffing: Trained nurses; typically 1:1 (unstable) or 1:2 (stable) patient ratio.

⭐ Aldrete score is a key tool for assessing PACU discharge readiness (target ≥9).

Patient Admission & Assessment - Check-In Champs

• Handover (OT → PACU): Key info exchange.
  • Patient ID, procedure, anesthesia type.
  • Intraop: blood loss, fluids, issues.
  • Analgesia, NPO.
  • 📌 Mnemonic: Use SBAR/I-PASS for structured handover.
• Initial Assessment (ABCDE):
  • Airway: Patency, airway adjuncts?
  • Breathing: Rate, SpO₂, auscultation.
  • Circulation: HR, BP, IV access.
  • Disability: LOC (Aldrete), pupils.
  • Exposure: Temp, site, drains.
• Monitoring: ECG, SpO₂, NIBP (q5-15min), pain score.

⭐ The Aldrete score is a key tool for PACU discharge readiness; a score of ≥9 is typically needed.

PACU Monitoring - Vigilance Masters

• Core Vitals (Continuous/Frequent):
  • ECG: Arrhythmia, ischemia detection.
  • SpO₂: Target >94% (unless chronic lung disease).
  • NIBP: q5-15 min; assess for hypo/hypertension.
  • Respiratory Rate & Pattern: Observe for adequacy.
  • Temperature: Prevent hypothermia (<36°C).
• Additional Monitoring:
  • Pain Score: Assess and manage.
  • Level of Consciousness: e.g., Aldrete Score.
  • Urine Output: If catheterized, >0.5 mL/kg/hr.

⭐ Continuous pulse oximetry (SpO₂) is mandatory for all patients in PACU to detect hypoxemia early; it's often considered the "fifth vital sign" in this setting.

PACU Discharge Criteria - Gate Keepers

• Aldrete Score: Assesses readiness. Target: >9 (or pre-op baseline).
  • 📌 Mnemonic: A CROP (Activity, Circulation, Respiration, Oxygen saturation, Consciousness). Each scored 0, 1, or 2.
• Other Key Criteria:
  • Stable vitals (≥30 mins).
  • Pain controlled (VAS <4).
  • Nausea/vomiting minimal.
  • No active bleeding; surgical site satisfactory.
  • Return of reflexes (if regional anesthesia).

⭐ Modified Aldrete Score, incorporating SpO2, requires ≥9 for safe discharge from PACU Phase I.

High‑Yield Points - ⚡ Biggest Takeaways

• Aldrete Score (≥9) is key for PACU discharge, assessing activity, respiration, circulation, consciousness, SpO2.
• Manage PONV with prophylaxis; risk factors include female, non-smoker, history, postoperative opioids.
• Treat hypothermia (<36°C) to prevent shivering, ↑O2 demand, and impaired coagulation.
• Prioritize multimodal pain management and regular assessment for optimal patient comfort.
• Vigilantly monitor for airway obstruction and hypoxemia, ensuring adequate oxygenation.
• Investigate delayed emergence for causes like hypoglycemia or residual drug effects.
