Surgical Apgar Score (SAS)
10-point score at the end of general or vascular surgery predicting major complications and death within 30 days, from estimated blood loss, lowest mean arterial pressure and lowest heart rate. Lower score = higher risk. Developed in adults.
Score interpretation
SAS 9–10 — about 4–5 % major complications or death within 30 days (Gawande 2007; Regenbogen 2009)
→ Routine post-operative monitoring; standard ward care appropriate; ERAS (Enhanced Recovery After Surgery) pathway if applicable; standard analgesia; reassess if clinical deterioration
SAS 7–8 — intermediate risk, lower than scores ≤ 6
→ Ward-based post-operative monitoring; ensure adequate fluid resuscitation; observe for complications (haemorrhage, infection, AKI, respiratory); escalate if NEWS2 rising; standard enhanced recovery pathway; GP follow-up arranged
SAS 5–6 — intermediate risk, higher than scores ≥ 7
→ Level 1 or HDU monitoring recommended postoperatively; fluid balance charting; regular NEWS2 assessments; early senior review if deteriorating; ensure IV access maintained; thromboprophylaxis; nutritional support; surgical review at 24 and 48 hours
SAS 0–4 — about 56–59 % major complications or death within 30 days (Gawande 2007; Regenbogen 2009)
→ Consider HDU/ICU-level monitoring; optimise haemodynamics and fluid balance; senior surgical, anaesthetic and critical care review; low threshold to investigate complications
