Any	Airway adjunct in situ	1:1

● ABCDE Framework — Systematic Post-Operative Assessment

Perform a full ABCDE assessment within 5 minutes of PACU arrival and repeat every 15 minutes minimum in Phase 1 (or more frequently if unstable). Document each parameter with time stamp.

Airway

Is the airway patent? Look, listen, feel for air movement. Is an ETT or LMA still in situ?

Patent, self-ventilating: observe and monitor — position supine or lateral recovery
Partial obstruction (snoring, stridor): jaw thrust, chin lift; insert oral airway (Guedel) or nasopharyngeal airway
Lateral recovery position if sedated and airway not protected — reduces aspiration risk
Deteriorating airway: call anaesthetist immediately — consider re-intubation
Check for residual LMA in situ — do NOT remove until patient is awake and opening mouth on command

Breathing

Respiratory rate: normal 12–20 bpm; <8 = opioid toxicity alert; >24 = distress/pain/hypoxia
SpO2: target ≥95% (or per individual prescription); <92% requires urgent intervention
Chest rise: symmetrical? Asymmetry may indicate pneumothorax (post-thoracic/neck surgery)
Breath sounds: auscultate bilaterally — wheeze (bronchospasm), stridor (laryngospasm/subglottic oedema), silence (obstruction)
Supplemental O2: apply per protocol; wean guided by SpO2 as patient wakes
ETCO2: if available, confirms ventilation; rising EtCO2 = hypoventilation

Circulation

BP: compare to pre-op baseline; hypotension >20% below baseline requires assessment
HR: tachycardia (pain, hypovolaemia, fever, atropine effect); bradycardia (opioids, beta-blockers, vagal, high spinal)
Peripheral perfusion: capillary refill time (<2 sec), colour, temperature of extremities
IV access: patent, positioned correctly, no extravasation, correct rate of infusion
IV medications: confirm current infusions match post-op orders — vasopressors, insulin, heparin
ECG rhythm: review trace — atrial fibrillation common post-cardiac/thoracic surgery

Disability (Neurological Status)

AVPU: Alert / Voice / Pain / Unresponsive — initial rapid assessment
Ramsay Sedation Scale: 1=anxious; 2=cooperative (target); 3=responds to commands; 4=responds briskly to stimuli; 5=sluggish; 6=no response — target 2–3 in PACU
Response to commands: squeeze my hand, open your eyes, stick out tongue
Pupils: bilateral, equal, reactive — pinpoint = opioid toxicity; unequal = neurological concern
Pain score: NRS 0–10 on awakening; CPOT if unable to self-report
Block height (if spinal/epidural): dermatomal level using ice or cold spray; document regression

Exposure

Wound dressing: intact, no strike-through; mark borders of any saturation to track progression
Drain output: document type (redivac, chest, pelvic), volume, colour (frank blood vs serous) — >100ml/hr from surgical drain = alert surgeon
Urinary catheter: urine output ≥0.5ml/kg/hr; haematuria; catheter patency
Temperature: core temperature via tympanic or oesophageal probe; <36°C = hypothermia — initiate Bair Hugger immediately
Pressure areas: check sacrum, heels — prolonged theatre time increases risk; reposition as tolerated
NGT: patent, position confirmed, free drainage

● Temperature Management

        Hypothermia (<36°C) is the most common finding on PACU arrival. Caused by theatre environment, open body cavities, cold IV fluids, vasodilation from anaesthetic agents.
      

Consequences of Hypothermia

Impaired coagulation — increased bleeding
Delayed drug metabolism — prolonged sedation
Shivering — increased O2 demand (up to 500%)
Patient discomfort and anxiety
Prolonged PACU stay
Increased surgical site infection risk

Warming Actions

Forced-air warming blanket (Bair Hugger) — apply immediately if <36°C
Warm IV fluids via fluid warmer
Increase ambient temperature if possible
Additional warm blankets over extremities
Reassess temperature every 30 min until ≥36.5°C
Treat shivering: meperidine 12.5–25mg IV if ordered

● Consciousness Assessment Tools

Ramsay Sedation Scale

Score	Description	Target
1	Anxious, agitated, restless
2	Cooperative, oriented, tranquil	✓
3	Responds to commands only	✓
4	Brisk response to light glabellar tap
5	Sluggish response to stimuli
6	No response	⚠

CPOT (Critical Care Pain Observation Tool)

For sedated or ventilated patients unable to self-report pain — assesses: facial expression (0–2), body movements (0–2), muscle tension (0–2), compliance with ventilator / vocalisation (0–2). Score ≥3 indicates pain requiring treatment.

    Any deterioration: call for help early. Do not manage PACU emergencies alone. Activate the code blue / anaesthetic emergency team if patient is deteriorating and not responding to initial interventions.
  

▲ Airway Obstruction

Trigger: Snoring, stridor, paradoxical breathing, absent air movement, SpO2 falling

Jaw thrust + chin lift — displace mandible anteriorly to lift tongue off posterior pharynx
Insert nasopharyngeal airway (NPA) — better tolerated in semi-conscious patient (size 6–7 for adults)
Insert Guedel oral airway if unconscious and no gag reflex
Position: lateral recovery position — prevents tongue falling back, reduces aspiration risk
Apply 100% O2 via non-rebreather mask 15L/min
Call anaesthetist urgently — consider LMA or re-intubation if not improving
Suction oropharynx if secretions or blood visible

      Common cause in PACU: residual neuromuscular blockade — check TOF ratio, consider sugammadex if suspected.
    

▲ Laryngospasm

Trigger: High-pitched stridor or complete silence with chest wall movement, SpO2 rapidly falling, patient distressed

Call for help immediately — one nurse stays with patient
Remove any airway stimulant (secretions, blood, suction catheter)
Apply tight CPAP via face mask with 100% O2 — jaw thrust with bilateral hand technique (Larson's manoeuvre)
Partial spasm: CPAP + suction + reassurance usually resolves
Complete spasm / SpO2 <90%: IV suxamethonium 0.5–1mg/kg — call anaesthetist for intubation
Prepare for emergency intubation — laryngoscope + ETT + syringe of suxamethonium drawn up
IV propofol 0.5mg/kg can break partial spasm if IV access available and anaesthetist present

Suxamethonium (succinylcholine)

Adult: 1mg/kg IV for complete laryngospasm. Paediatric: 2mg/kg IV or 4mg/kg IM if no IV access. Have atropine ready (bradycardia risk in paediatrics).

▶ Respiratory Depression — Opioid-Induced

Trigger: RR <8 bpm, SpO2 <92%, pinpoint pupils, excessive sedation (Ramsay 5–6), difficult to rouse

Stimulate patient verbally and physically — pain is reversal of opioid effect
Apply 100% O2 via non-rebreather mask 15L/min
Assist ventilation with BVM if RR <6 or SpO2 not recovering
Prepare naloxone — draw up 400mcg in 10ml normal saline = 40mcg/ml
Give naloxone 40–80mcg IV every 2–3 minutes titrating to RR >10 and adequate consciousness
Do NOT give full 400mcg bolus — causes acute pain, vomiting, hypertension, pulmonary oedema
Naloxone duration shorter than opioids — monitor closely for re-sedation, repeat doses as needed
If PCA in situ — STOP PCA until reassessed

Naloxone (Narcan)

Titrated IV: 40mcg every 2–3 min. IM route if no IV: 400mcg. Infusion: 2/3 of effective reversal dose per hour if re-sedation anticipated. Paediatric: 10mcg/kg IV.

▶ Hypotension (SBP <90 mmHg or >20% below baseline)

Trigger: Low BP, tachycardia, pallor, cold clammy skin, falling urine output, drain with excessive output

Assess: haemorrhagic vs vasodilatory vs cardiogenic cause
Elevate legs (Trendelenburg if not contraindicated) — passive leg raise as fluid challenge test
IV fluid bolus: 250–500ml crystalloid (NaCl 0.9% or Hartmann's) over 15 minutes
Check surgical drain — >100ml/hr frank blood = notify surgeon urgently
Check epidural/spinal level — sympathectomy causes vasodilation — vasopressor (ephedrine 3–6mg IV bolus)
Vasopressor options: ephedrine 6mg IV bolus or phenylephrine 100mcg IV (if HR adequate)
Review all anaesthetic agents — prolonged spinal block, residual volatile agents
If not responding to fluids + vasopressors: escalate to ICU — consider inotrope

      Catastrophic haemorrhage: large-bore IV access x2, crossmatch, urgent surgical review, activate massive transfusion protocol if indicated.
    

▶ Hypertension (SBP >160 or >20% above baseline)

Trigger: Elevated BP, may be accompanied by agitation, pain, headache, tachycardia

Identify and treat the cause first — pain (most common), urinary retention (distended bladder), agitation
Ensure adequate analgesia — treat pain before antihypertensives
Check for urinary retention — catheterise if bladder distended
If pain excluded and BP persists >180 systolic: notify anaesthetist
Antihypertensives: labetalol 5–10mg IV increments (combined alpha/beta), or hydralazine 5–10mg IV
Hypertensive emergency (BP >200 + symptoms): GTN infusion, urgent medical review

▶ PONV — Post-Operative Nausea & Vomiting

Trigger: Nausea, retching, vomiting — highest risk: female, non-smoker, history of PONV/motion sickness, opioid analgesia, volatile anaesthesia

Position patient lateral — critical if sedated (aspiration risk with reduced protective reflexes)
Suction oropharynx if vomiting occurred — ensure airway is clear
Oxygen via mask — hypoxia worsens nausea
Ondansetron 4mg IV slowly — first-line 5-HT3 antagonist
Metoclopramide 10mg IV if ondansetron insufficient (avoid in Parkinson's patients)
Dexamethasone 4–8mg IV if prescribed (often given intraoperatively prophylactically)
Cyclizine 50mg IV/IM — alternative antihistamine antiemetic
Avoid sudden movements and maintain hydration

      Aspiration risk: If patient vomits with reduced consciousness — position lateral, suction, high-flow O2. Notify anaesthetist. Consider chest X-ray. Monitor for aspiration pneumonitis (tachypnoea, fever, falling SpO2).
    

▶ Emergence Agitation / Delirium

Trigger: Confused, combative, disoriented patient — pulling at lines, thrashing — common post desflurane/sevoflurane, paediatrics, elderly

Ensure patient safety — padded side rails, prevent line dislodgement, staff at bedside
Rule out treatable causes: hypoxia (SpO2), hypoglycaemia (BGL), urinary retention, pain, hypothermia
Reorient: speak calmly, tell patient they are in the recovery room, surgery is finished
Familiar cues: nurse speaking patient's preferred language, family voice if allowed
Treat pain — agitation often represents undertreated pain
If persistent and distressing: small dose IV midazolam 0.5–1mg (with anaesthetic review)

● Pain Assessment in PACU

Numerical Rating Scale (NRS)

Ask patient to rate pain 0–10 where 0 = no pain, 10 = worst imaginable pain.

0–3: Mild — monitor 4–6: Moderate — treat 7–10: Severe — urgent

CPOT for Sedated Patients

Domain	0	1	2
Facial expression	Relaxed	Tense	Grimacing
Body movements	No movement	Protection	Restlessness
Muscle tension	Relaxed	Tense/rigid	Very rigid
Vocalisation	No sound	Moaning	Crying/screaming

CPOT ≥3 indicates significant pain — treat and reassess within 30 minutes.

● Multimodal Analgesia Principles

Multimodal analgesia combines drugs with different mechanisms to reduce opioid requirements and side effects. Standard PACU multimodal regimen:

IV Paracetamol 1g over 15 min QDS — baseline non-opioid
IV Ketorolac 15–30mg QDS (if renal function OK, not in elderly >65, avoid in renal impairment, GI risk, post cardiac surgery)
IV Opioid titration — morphine or fentanyl per protocol
Regional anaesthesia top-up — epidural, spinal, nerve block
PCA initiation — patient-controlled analgesia for appropriate patients
Oral analgesia — begin when tolerating oral (diclofenac 50mg TDS, tramadol)

● IV Opioid Titration Protocol — Morphine

      Nurse-administered IV opioid titration is a core PACU skill. Requires: prescription, monitoring, trained nurse, suction and naloxone immediately available.
    

Standard Adult Protocol

Confirm prescription and allergies
Baseline: RR, SpO2, sedation score, NRS
Morphine 2–3mg IV over 2 min
Wait 5 minutes — reassess NRS and sedation
If NRS ≥4 AND Ramsay ≤3 AND RR ≥10: repeat
Continue titrating until NRS <4 or maximum dose reached
Document each dose, time, pain score, sedation, SpO2, RR
Transition to PCA when patient alert and comfortable

Withhold Opioid If:

          RR <10 bpm
SpO2 <94% on supplemental O2
Ramsay sedation score ≥4
Systolic BP <90 mmHg
Excessive sedation — unable to maintain own airway

        

Fentanyl Alternative

Fentanyl 25–50mcg IV boluses (faster onset, shorter duration) — preferred in renal impairment, elderly, or when rapid effect needed. Duration 30–60 min vs morphine 3–4 hours.

● PCA — Patient-Controlled Analgesia

Initiation in PACU

Patient must be awake, cooperative, understand concept
Demonstrate use before initiating
Standard morphine PCA: 1mg bolus / 5 min lockout / 4-hour limit 20mg
Connect to dedicated IV port — do NOT co-infuse with other fluids
Label PCA syringe clearly
Document start time, concentration, lockout, limit

PCA Monitoring

RR and sedation score hourly minimum
SpO2 continuous in PACU, hourly on ward
Document attempts vs deliveries every 4 hours
If excessive attempts with poor pain control: review prescription, consider background infusion
Only patient to press PCA button — educate family not to press

● Regional Anaesthesia Assessment

Epidural Assessment

Sensory level: ice cube / cold spray test — ask patient to compare cold sensation on chest vs abdomen vs legs; document highest level blocked
Motor block: Bromage scale — 0=full movement, 1=cannot flex hip, 2=cannot flex knee, 3=cannot flex ankle; document bilaterally
BP: sympathetic blockade causes vasodilation — monitor closely, treat hypotension with fluids then vasopressor
Epidural site inspection: dressing intact, no leakage, no haematoma
Check epidural infusion pump: rate, drug concentration, remaining volume

Spinal — Regression Monitoring

Document time of spinal injection and peak block height
Monitor regression of sensory block every 30 min
Patient may not mobilise until bilateral leg movement returns fully (Bromage 0 bilaterally)
Bladder care: urinary retention common with spinal — catheterise if not voided and bladder distended

● Breakthrough Pain Management Escalation

NRS Score	Action	Escalation
0–3	Regular multimodal analgesia, reassess in 1 hour	None required
4–6	IV opioid bolus per protocol + reassess in 30 min	Notify if no improvement after 2 doses
7–10	Urgent IV opioid titration, consider regional top-up if epidural in situ	Notify surgeon/anaesthetist; consider ketamine 0.1–0.2mg/kg IV sub-dissociative
Any with adverse effects	Withhold opioid, treat adverse effect (PONV, sedation, respiratory depression)	Review analgesic plan with anaesthetist

● PADSS — Phase 2 / Day Surgery Discharge

Post-Anaesthetic Discharge Scoring System — for day case / ambulatory discharge home. Each domain 0–2; must score 9/10.

Vital signs: within 20% of pre-op baseline
Ambulation: steady gait, no dizziness, at pre-op level
Nausea/vomiting: minimal, controlled with oral antiemetics
Pain: minimal, controlled with oral analgesics
Surgical bleeding: minimal, no dressing change required

Additional Day Case Discharge Requirements

Responsible adult escort arranged
Private transport (no driving for 24 hours)
Written post-op instructions in patient's language
Emergency contact number provided
Oral intake tolerated (not mandatory for all procedures)
Voided urine (especially post-spinal or pelvic surgery)

● Special Patient Groups in PACU

Obese Patient / OSA

Position: 30° head-up (reverse Trendelenburg) — improves FRC, reduces airway collapse
High risk of upper airway obstruction — tongue and soft tissue obstruction worsened supine
SpO2 monitoring mandatory — may desaturate rapidly
CPAP equipment at bedside — initiate if repeated desaturation or known OSA with home CPAP
Avoid over-sedation — do not give benzodiazepines without anaesthetic review
Opioids with caution — consider multimodal with maximum non-opioid component
Prone to GORD — avoid flat positioning; head of bed elevated

Elderly Patient (65+)

POCD risk (Post-Operative Cognitive Dysfunction) — confusion common
Reorient frequently — lights on, clock visible, familiar faces
Avoid unnecessary sedation; NSAIDs require renal function check
Higher risk of hypothermia — aggressive warming
Pressure area vigilance — skin fragility

Paediatric PACU

Parental presence evidence-based — reduces emergence agitation, distress — standard in GCC paediatric centres
Distraction during emergence: favourite toy, video, familiar music
Sugar soother (oral sucrose) — neonates and infants for minor discomfort
Weight-based drug dosing — verify weight before any medication
Paediatric normal vital sign ranges differ — use age-appropriate reference charts
Stridor post-extubation: nebulised adrenaline 1:1000 0.5ml/kg (max 5ml) + dexamethasone

Obstetric / High-Risk

Epidural LA toxicity (LAST) — circumoral tingling, tinnitus, metallic taste, seizures → Intralipid 20% protocol
Intralipid 20% must be immediately available in PACU where epidurals in situ
Post-spinal headache (PDPH) — monitor and document, lie flat, hydrate, analgesia, caffeine; blood patch if severe
Post-caesarean: uterine tone, lochia, BP (post-spinal hypotension risk)

● GCC Surgical Volumes & PACU Capacity

GCC countries — particularly Saudi Arabia, UAE, Kuwait, Qatar — operate large tertiary hospitals with 10–20+ operating theatres running extended hours including evenings and weekends. PACU capacity and staffing must match this throughput.

Extended Hours Challenges

Evening and night PACU lists — reduced consultant cover; PACU nurses must be confident to manage independently within scope
Surgeon leaves theatre before PACU stabilisation complete — escalation pathways must be clear
High patient turnover — documentation discipline critical
Simultaneous admissions from multiple theatres — staffing ratio vigilance

Ramadan Considerations

        Some GCC centres reduce elective surgical lists during Ramadan due to fasting-related anaesthetic considerations. Emergency lists continue unchanged. Iftar timing can affect scheduling of afternoon lists. Pre-op fasting confirmation requires cultural sensitivity — confirm NPO status directly and non-judgementally.
      

● GCC PACU Nursing Workforce

PACU nursing is one of the most specialised clinical areas. GCC hospitals recruit PACU-experienced nurses internationally due to regional shortage.

Common Source Countries

United Kingdom Australia / NZ Philippines India South Africa USA / Canada

Professional Certifications Valued

CPAN — Certified Post Anaesthesia Nurse (ABPANC, USA)
CAPA — Certified Ambulatory Perianesthesia Nurse (ABPANC, USA)
ASPAN standards widely used as PACU practice framework
UK RCOA / Anaesthesia Associates endorsement
Prometric/DataFlow registration required for GCC licensing

● High Obesity Prevalence in GCC Surgical Patients

GCC countries have among the highest rates of obesity and type 2 diabetes globally. This significantly impacts PACU management.

Implications for PACU Nursing

OSA in undiagnosed patients — many GCC patients have undiagnosed obstructive sleep apnoea; maintain high index of suspicion
Larger body habitus complicates positioning, pressure area care, IV access
Longer anaesthetic emergence — increased volume of distribution for lipophilic agents
Bariatric patients: 30° head-up positioning is non-negotiable; manual handling requirements
CPAP equipment should be standard in PACU — not just available on request

Glucose Monitoring — Diabetic Patients

        Monitor blood glucose every 30–60 minutes in PACU for all known diabetic patients and patients on insulin infusions. Surgical stress response and perioperative fasting create significant glycaemic instability. Target glucose 6–10 mmol/L (108–180 mg/dL) per institutional protocol.
      

● Cultural Aspects of PACU Care in GCC

Family Presence & Communication

Families in GCC expect immediate updates post-surgery — long waits without information cause significant distress
Families often congregate outside PACU in large numbers — designated family liaison nurse or coordinator is best practice
Some families insist on entering PACU — policies vary by institution; explain restrictions respectfully
Communicate via a single family spokesperson to reduce repeated queries
Gender preferences: female patients may prefer same-gender nursing where possible
Inform family of expected PACU stay duration proactively

Language & Pain Assessment

        NRS pain scale works across language barriers — use hand signals, show patient the 0–10 scale on a card. Arabic numerals are widely understood. Visual analogue scales (VAS) and faces pain scale useful for patients with limited English. Always have translator access — avoid using family as pain interpreters when possible.
      

● Hajj Season Surgical Surge — Saudi Arabia

During the annual Hajj season, the Kingdom of Saudi Arabia — particularly Makkah, Madinah, and Jeddah — experiences a massive surge in population (2–3 million pilgrims). This creates unique challenges for PACU nursing in regional hospitals.

Emergency Surgical Surge

Mass casualty events (crowd crush, heat stroke, trauma) can require simultaneous activation of multiple theatres
PACU capacity may be overwhelmed — surge protocols activate overflow areas
International pilgrims with unknown medical history, multiple languages
Limited family contacts available for consent / information
Higher rates of neglected pathology presenting urgently

PACU Surge Preparedness

Pre-Hajj staff deployment planning — additional PACU nurses rostered
Elective lists may be reduced or suspended in affected cities
Escalation criteria reviewed and drilled before season
Translation resources available — Arabic, Urdu, Malay, Indonesian, English minimum
Blood bank liaison — cross-match turnaround critical

      PACU nurses working in Makkah/Madinah/Jeddah or Mina hospitals during Hajj season should receive specific surge orientation and will be working in one of the most demanding PACU environments in the world.
