Obesity, deconditioning, nephrectomy

58 yo F with renal mass → renal clear cell carcinoma and increasing in size 

Background 

  1. Goitre → T3/4 normal and TSH suppressed. 
  2. OSA – CPAP
  3. AF o SVT/rAF post induction previously 
  4. HFpEF 

Issues: 

  • Physical deconditioning
    • BMI 46 
    • Mobilises with wheelchair 
  • Current smoker 
  • Complicated perioperative course – Breast WLE 2023. Poor wound healing post excision and infection. Required re-intubation and ICU post-operatively 
  • Multiple visits to perioperative clinic – decision not to proceed to surgery made by 2 senior anaesthetists based on significant co-morbidities.
    • Recent Cystoscopy and RPG/lithotripsy for renal calculus – uneventful surgery
    • Request for surgery re-submitted 

Discussion 

Perioperative Optimisation 

  • Minimal changes so far with lifestyle modification – obesity, smoking 
  • Recommendation not to proceed is not preclusive 
  • Patient has been extensively counselled on perioperative risk and wishes to proceed. 
  • Issue now is optimisation and prevention of post-operative complications – biggest risk PPC 
  • Risk factors should be re-addressed with the new incentive of a surgery date
    • Weight loss – consider addition of GLP-1 analogue 
    • Smoking cessation – coaching previously offered, consider Champix? 
    • Prehabiliation 

Plan: 

  • Metabolic clinic referral 
  • Prehabilitation 
  • Post op disposition: CPAP, HDU – do not start without HDU bed confirmed given previous extubation failure.
