Planned Procedure
Elective Total Hip Arthroplasty (right side)

Past Medical History
Hypertension well-controlled on medication, Type 2 Diabetes Mellitus managed with diet and metformin (HbA1c 6.8%), osteoarthritis affecting multiple joints, and a history of well-controlled anxiety. No known cardiovascular disease, respiratory disease, or renal impairment.
Previous Anaesthetic History
Previous uncomplicated anaesthetic for laparoscopic cholecystectomy 5 years ago. No reported airway difficulties, postoperative complications, or PONV.
Medications
Lisinopril 10mg OD, Metformin 500mg BD, Atorvastatin 20mg OD, Paracetamol 1g QDS PRN. No anticoagulants, antiplatelets, steroids, or biologics.
Allergies
Penicillin (rash)
Airway Assessment
Mallampati Class II, good mouth opening (>3 fingerbreadths), intact dentition, thyromental distance >6cm, full neck mobility, good jaw protrusion.
Cardiorespiratory Review
No reported chest pain, dyspnoea, orthopnoea, or syncope. Good exercise tolerance (can walk 2 flights of stairs without stopping). No wheeze or history of sleep apnoea.
Investigations
Full Blood Count: WNL. Urea & Electrolytes: WNL. Liver Function Tests: WNL. ECG: Sinus rhythm, no ischaemic changes. HbA1c: 6.8%.
Peri-Operative Risk Assessment
ASA Physical Status II. Peri-operative risk is low. Main drivers of risk are well-controlled hypertension and Type 2 Diabetes. Using the Revised Cardiac Risk Index (RCRI), the patient has 0 risk factors, indicating a low risk of major cardiac events. SORT score also indicates a low risk for elective hip arthroplasty in this demographic. Estimated peri-operative mortality risk is <1%, and significant morbidity risk (e.g., major cardiac events, stroke) is also low (1-5%).
Optimisation Required
No further investigations or specialist referrals are immediately required. Continue current medications. Advised to take usual morning medications with a small sip of water on the day of surgery, excluding Metformin which should be omitted on the morning of surgery.
Postoperative Care
Anticipated ward-based care with standard enhanced recovery pathway. No anticipated HDU/ICU requirements.
Final Impression
Low peri-operative risk. Patient is suitable for elective total hip arthroplasty from an anaesthetic perspective following routine pre-operative preparation.
