Anaesthesia for the obese patient

Beware of:

‘Apple’ fat distribution (central obesity)

Metabolic syndrome (3 of central obesity, hyper-tension, cholesterol, sugars, lipids)

 

Tips:

Pre-op: STOPBANG >5 = high risk of disordered breathing/OSA

AR: Consider test dose of 50mcg fentanyl pre-induction for sensitivity for opioids

RSI: No evidence

Drug dosing: Ideally use LBW. Practically IBW + few kg. For all drugs except suxamethonium and neostigmine

Position: Reverse trendelenburg with pillow under shoulders for tragus above sternum, rather than break in the bed

Extubation: consider NPA with lidocaine

Post-op: avoid ‘tying’ to the bed e.g. with a-line, infusions

Tips:
Give IM atropine with IM sux
In obese O2 consumption is significantly greater during SV rather than IPPV
Epidural blood patch recommend 20ml
Dural puncture: inject 20ml normal saline down intrathecal catheter
NSAIDs may affect  platelets and clot strength of EBP
In difficult airway consider nasendoscopy.
AFOI topicalise. Reduce secretions by suction catheter or Yanker (also tests topicalisation)
Legal position: Prudent doctor  -> prudent patient
Coding Рappropriately Рgets the organisation appropriate money
Quality measures – e.g. length of stay
How to add value ? Outcome or quality / cost
In a report, if used a guideline say so
Detail discussions with patients, including apologies
