Anesthetic Goals

Remember the pillars of a balanced anesthetic

  • Amnesia: hypnotic depth
  • Analgesia: response to stimulus
  • Akinesia: surgical field immobility

Your anesthetic plan starts with considering what the surgery and patient require in each of these categories

Hemodynamic Planning Tips

Again, consider what the surgery and patient require, and at what time during the operation, you have those goals

Examples

  • NSGY - often need SBP < 140 to mitigate bleeding intaop and postop
  • CEA - might need SBP > 170 prior to reperfusion to maintain cerebral perfusion through collaterals, and then SBP < 140 after reperfusion
  • Cardiac surgeries on CBP - where CTS will cannulate the aorta, SBP goal ~90 to prevent aortic dissection

Think about goals/targets & what agents you plan to use

  • Rate - beta blockers, anticholinergics, pacemaker
  • Rhythm - pads on to cardiovert if needed
  • Preload - augment with volume, euvolemia, venodilators
  • Afterload - vasopressors
  • Contractility - inotropes
Positioning
  • Proneview, padding, circuit extenders
  • Check arm placement, head/neck alignment
  • Pressure point protection
  • Eye protection for prone cases
