Postoperative Respiratory Impairment Is a Real Risk for Our Patients: The Intensivist’s Perspective

Table 1

Respiratory risk stratification scoring systems [20, 22, 25].

STOP-BANG Questionnaire [22]	Use	Screen/stratify risk of OSA
	Components	Snoring	BMI > 35 kg/m^2
		Tiredness	Age > 50 years
		Observed apnea	Neck circumference (large size)
		High blood pressure	Gender (male)
	Interpretation	0–2: low risk
		3-4: intermediate risk
		5–8: high risk
SPORC (Score for the Prediction of Postoperative Respiratory Complications [25])	Use	Risk stratification for development of postextubation respiratory failure requiring reintubation
	Components	ASA score ≥ 3	3 points
		Emergency procedure	3 points
		High-risk service	2 points
		Congestive heart failure	2 points
		Chronic pulmonary disease	1 point
	Interpretation	0 points	Reintubation probability 0.1%
		3 points	Reintubation probability 0.5%
		5 points	Reintubation probability 1.5%
		7 points	Reintubation probability 4.2%
		9 points	Reintubation probability 11.2%
ARISCAT (Assess Respiratory Risk in Surgical Patients in Catalonia [20])	Use	Risk stratification for the development of postoperative pulmonary complications
	Components	Age
		≤50 years	0 points
		51–80 years	3 points
		>80 years	16 points
		Preoperative oxygen saturation
		≥96%	0 points
		91–95%	8 points
		≤90%	24 points
		Other clinical risk factors
		Respiratory infection (in prior month)	17 points
		Preoperative hemoglobin ≤10 g/dL	11 points
		Emergency surgery	8 points
		Surgical incision
		Upper abdominal	15 points
		Intrathoracic	24 points
		Duration of surgery
		<2 hours	0 points
		2–3 hours	16 points
		>3 hours	23 points
	Interpretation	<26 points: low risk
		26–44 points: moderate risk
		≥45 points: high risk
