LIDOCAINETraditional Indications
Tight Brains
“There is currently no evidence to support the use of intravenous lidocaine as a pretreatment for RSI in patients with head injury and its use should only occur in clinical trials”
Robinson N, Clancy, M. Emergency Medicine Journal 18(6):453-7, 2001
Tight Lungs
“…no study has demonstrated a protective effect of [both intravenous and topical anesthetic agents] in preventing bronchospasm after intubation..”
Maslow et al. Anesthesiology, 93(5): 1198-1204, 2000
OPIOIDS (Fentanyl)
Traditional Indications
1. Blunt hemodynamic response
2. Decrease pain
Adachi et al. Anesthesia & Analgesia. 95(1):233-7, 2002
FENTANYL DOSE
Dose = 3µg/kg* IV slow push
*Beware of hypotension and apnea
ATROPINEStandard practiceGive atropine to:
1. all children less than 8 years old2. prior to second dose of succinylcholine
Dose = 0.01-0.02 mg/kg IVP
Evidence is mounting that questions routine use of atropine
Fastle et al. Pediatr Emerg Care;20(10):651-5, 2004McAuliffe et al. Can J Anaesth; 43(7) 754-5,1996Fleming et al. CJEM. 2005;7(2):114-7
DEFASCICULATING DOSEOne tenth the RSI dose
Traditional Indications
1. Blunt rise in ICP
2. Decrease risk of aspiration
3. Prevent muscular pain
Clancy et al. Emergency Medicine Journal. 18(5):373-5, 2001
Questionable value
“no definitive evidence that SCh caused a rise in ICP”“no studies that investigated the issue of pretreatment with defasciculating doses and their effect on ICP”
And what’s more…
DEFASCICULATING DOSEcan be downright dangerous*
* it may cause premature apnea
PRETREATMENTt – 3 minutes
If you’re going to give these drugs:
…at least give them some time to circulate (3 minutes)

Making non-depolarizing agents FASTER
1. Large Doses
2. Priming Doses
3. Better Induction Agents
}Increase duration
The Choice of Induction Agent
ETOMIDATE – the agent of choice
THIOPENTAL – hypotension
– not the greatest intubating conditions
PROPAFOL – hypotension
– storage, allergy concerns
KETAMINE – not the greatest intubating conditions
– some like it for asthma
– good for penetrating neck trauma
MIDAZOLAM – effective induction doses cause hypotension
– usually underdosed (requires 0.3mg/kg)
– better for conscious sedation
