Here's a contrarian view: Neuraxial + GA w/ ETT (0.5 MAC) +/- regional (adductor, PENG, etc.) = great technique.
Benefits:
- neuraxial narcotic = postop pain control, minimal postop narcotics
- neuraxial bupi = intraop pain control, minimal intraop narcotics
- supplemental regional block = post-op pain control, minimal postop narcotics
- paralysis = satisfies surgeon's preference for "optimal operating conditions" aka relaxation
- fast wakeup since not a lot of inhalational on board
- presumably less PONV and POCD due to less inhalational
- no need for jaw thrusts, oral airways, or adjusting malpositioned LMA's
- minimal hemodynamic issues when patient's hydrate and you're running 0.5 MAC
- zero intra-op narcotic use therefore less PONV compared w/ straight GA
- if slow surgeon, no problem because you're already prepared to extend the anesthetic via inhalational or additional LA (if you have an epidural)
Disadvantages:
- More work for the anesthesiologist = no debate there.
- Time = minimal. A well prepared anesthesiologist knows how to parallel process and get this done safely and with rapid efficiency.
---- step 1) spinal/epidural
---- step 2) induction + tube (Have induction drugs and airway ready to go so right when you lay them down. Empirically give a little pre-induction pressor, minimal IV narcotic on induction because the sympathetic drive from ETT stimulation helps maintain BP)
---- step 3) operate
---- step 4) regional drugs and needle and ultrasound ready to go prior to extubation
---- step 5) extubate to mask, continue monitoring EtCO2 while you're doing your. block
---- result: block is usually complete before the gurney even gets to the room, not to mention patient is wide awake by then
- "increased risk" = I call BS on this all day.
---- Airway? We have video laryngoscopes everywhere. Prefer an ETT over an LMA or oral airway any day.
---- Hemodynamics? Dude, don't run a full MAC of gas, obviously.
