STOP-BANG — OSA screening
Pre-op OSA risk + post-op opioid-monitoring decision
Mnemonic device
STOP-BANG (each = 1 point; ≥3 high risk; ≥5 very-high)
Mapping
S — Snoring
Loud snoring (heard through closed door)
T — Tired
Daytime fatigue / falling asleep during the day
O — Observed apnea
Witnessed apneas during sleep
P — Pressure
Hypertension (treated or untreated)
B — BMI
>35 kg/m²
A — Age
>50 years
N — Neck circumference
>40 cm (>17 in male, >16 in female)
G — Gender
Male
Clinical note: STOP-BANG ≥3 → prepare for difficult ventilation + difficult airway; ≥5 → very-high OSA risk → minimize opioid, multimodal pain plan, extended PACU + monitored bed, regional alternative if available. Avoid full-reversal of NMB without TOF >0.9.
