Induction and maintenance of general anesthesia

GOOD choice for RAPID induction in patient in precarious hemodynamic balance; perhaps especially one with ischemic heart disease, with or without intracranial pathology; or perhaps whenever hemodynamic stability is most important.

  • Rapid-sequence induction-intubation for intracranial bleed in patient with angina (will need some narcotic or other agent to blunt response to intubation).
  • IV sedation vs general anesthesia for short peripheral procedure on patient with mod-severe cardiomyopathy (e.g. cardioversion)

  • Induction 0.2 - 0.4 mg/kg (less after pre-med) IV
  • Rectal induction (peds) 6.5 mg/kg -> hypnosis in 4 min (stable hemodynamics, rapid recovery)
  • Maintenance:
    • Need 300 - 500 ng/ml plasma level
    • Note: "TECHNIC OF TENS":
        10x10 = 100 ug/kg/min for 10 mins then
        10 ug/kg/min and D/C 10 mins before awake
        (LOC usually occurs in 10x10 = 100 secs)
        Expect: hemodynamic stability, adequate spontaneous ventilation, less pain, myoclonus, phlebitis
