Clinical Decision Support

Interactive Perioperative Risk Calculators

Evidence-based risk stratification instruments validated for pre-anaesthesia clinics and surgical risk estimation. Select any calculator below to calculate instant scores and clinical recommendations.

Clinical Tool Notice: Intended for board-certified anaesthesiologists and surgical teams. Non-physician website visitors should refer to attending medical practitioners.

Validated Decision Support

Revised Cardiac Risk Index (RCRI / Lee's Score)

Estimates risk of Major Adverse Cardiac Events (MACE: MI, Cardiac Arrest, Complete Heart Block, Death)

AHA / ESC Class I Standard

Check all clinical risk predictors that apply to this patient:

High-Risk Surgery Intraperitoneal, intrathoracic, or suprainguinal vascular surgery

History of Ischaemic Heart Disease Prior MI, positive stress test, angina, nitrate therapy, prior PCI/CABG

History of Congestive Heart Failure Prior CHF episode, pulmonary edema, PND, S3 gallop, or elevated BNP

History of Cerebrovascular Disease Prior transient ischemic attack (TIA) or stroke / CVA

Diabetes Mellitus on Insulin Preoperative insulin therapy required for glycaemic control

Preoperative Serum Creatinine > 2.0 mg/dL Or baseline estimated GFR < 30 mL/min/1.73m²

Calculated Score & Risk Class

Score: 0 · RCRI Class I (Low Risk)

Estimated 30-Day Major Cardiac Complication Rate: 3.9% (Can proceed to elective surgery without routine cardiac stress testing if functional capacity ≥ 4 METs).

ARISCAT Postoperative Pulmonary Complications Score

Predicts in-hospital respiratory failure, pneumonia, atelectasis, and pleural effusion

Respiratory SIG Standard

Patient Age

Preoperative SpO2 on Room Air

Surgical Incision Site

Duration of Surgery

Respiratory Infection in Last 1 Month (+17 pts) Preoperative Anemia (Hb ≤ 10 g/dL) (+11 pts) Emergency Procedure (+8 pts)

Pulmonary Risk Stratification

Score: 0 · Low Pulmonary Risk

Estimated Postoperative Pulmonary Complication Rate: 1.6%. Standard incentive spirometry and early ambulation recommended.

Caprini Venous Thromboembolism (VTE) Risk Model

Determines indication for mechanical vs pharmacological thromboprophylaxis

Chest 2026 Guidelines

Major Open Surgery (> 45 Mins) (+2 pts) Or laparoscopic procedure exceeding 45 minutes

Active Malignancy / Cancer (+2 pts) Current or receiving chemotherapy within 6 months

Personal History of DVT / PE (+3 pts) Prior documented deep vein thrombosis or pulmonary embolism

Elective Major Lower Extremity Arthroplasty (+5 pts) Total Hip, Total Knee, or Hip Fracture fixation

Caprini Score & Recommended Prophylaxis

Score: 0 · Very Low Risk

Early ambulation only. Pharmacological prophylaxis not routinely indicated unless risk profile changes.

OCTOBER 2026 DIGEST · NEJM / LANCET SELECTION Critique by: Dr. V. Narayana & Dr. S. Rao

Restrictive vs Liberal Vasopressors in Noncardiac Surgery (REVAS Trial)

Structured PICO Appraisal: In 2,500 adult patients with coronary disease undergoing non-cardiac surgery, targeting MAP > 75 mmHg with early continuous norepinephrine infusion reduced myocardial injury by 18% compared to reactive bolus phenylephrine without increasing tachyarrhythmias (RR 0.82; 95% CI 0.71–0.94; P = 0.004).

SOPPA Clinical Bottom Line: Continuous low-dose peripheral noradrenaline targeting physiological baseline MAP is superior to permissive hypotension and intermittent bolus rescue.
