Q

Which induction drug stimulates catecholamine release and why is it good?

A

Ketamine it’s good in sepsis because the catecholamines can actually raise blood pressure

Q

what is the other name for nimbex

A

cisastracurium

19
Q

what is the other name for succinylcholine

A

suxmethonium

20
Q

Why use fentanyl for sedation?

A

Fentanyl provides systemic analgesia and enhances the sedative effect of benzodiazepines. When midazolam-only sedation is ineffective, fentanyl can be considered as an adjunct

21
Q

when is fentanyl used

A

Clinically, its most frequent use is as a sedative in intubated patients and in severe cases of pain in patients with renal failure due to its primarily hepatic elimination

22
Q

what does RSI entail

A

Rapid sequence intubation (RSI) is an airway management technique that produces inducing immediate unresponsiveness (induction agent) and muscular relaxation (neuromuscular blocking agent) and is the fastest and most effective means of controlling the emergency airway

23
Q

what are the 9 Ps of RSI

A

PROCESS OF RSI

Remembered as the 9Ps:

Plan
Preparation (drugs, equipment, people, place)
Protect the cervical spine
Positioning (some do this after paralysis and induction)
Preoxygenation
Pretreatment (optional; e.g. atropine, fentanyl and lignocaine)
Paralysis and Induction
Placement with proof
Postintubation management

24
Q

what is SOAPME

A

SOAPME

Suction — at least one working suction, place it between mattress and bed

Oxygen — NRBM and BVM attached to 15 LPM of O2, preferably with nasal prongs for apneic oxygenation

Airways — 7.5 ET tube with stylet fits most adults, 7.0 for smaller females, 8.0 for larger males, test balloon by filling with 10 cc of air with a syringe — Stylet – placed inside ET tube for rigidity, bend it 30 degrees starting at proximal end of cuff (i.e. straight to cuff, then 30 degree bend) — Blade – Mac 3 or 4 for adults – curved blade — Miller 3 or 4 for adults – straight blade — Handle – attach blade and make sure light source works — Backups – ALWAYS have a surgical cric kit available! — have video laryngoscope, LMA and bougie at bedside

Pre-oxygenate – 15 LPM NRBM

Monitoring equipment/Medications — Cardiac monitor, pulse ox, BP cuff opposite arm with IV — Medications drawn up and ready to be given

End Tidal CO2
O2 MARBLES is an altern

25
Q

drawbacks of propofol

A

Drawbacks: hypotension, myocardial depression, reduced cerebral perfusion, pain on injection, variable response, very short acting

26
Q

What is the RSI combos that Dr. Oucha likes ?

A

Rox and Propofol or Sux and Etomodate

27

28
Q

tell me about propofol

A

Diprivan. EXTREMELY SHORT ACTING INDUCTION SEDATIVE
HIGHLY LIPID SOLUBLE AND RAPIDLY PENETRATES THE BLOOD-BRAIN BARRIER.

30
Q

why do we use neuromuscular blocking agents

TO INDUCE MUSCLE RELAXATION, THUS FACILITATING ENDOTRACHEAL INTUBATION.

31
Q

why do we use induction agents

A

FOR SEDATION ,PRIOR TO PARALYSIS, DURING RSI.

32
Q

tell me about lidocaine

A

ANTIDYSRHYTHMIC , CARDIO VASCULAR AGENT
CLASS 1B (RAPID SODIUM CHANNEL BLOCKER, SHORTENS REPOLARIZATION)
CNS AGENT
LOCAL ANESTHETIC
ACTION: SUPRESSES AUTOMATICITY OF ISCHEMIC ECTOPIC FOCI WITHOUT AFFECTING CONDUCTION. THOUGHT TO RAISE THE VENTRICULAR FIBRILLATION THRESHOLD.
USED IN RSI AS AN INDUCTION AGENT TO BLUNT ICP.
CONTRAINDICATIONS: KNOWN HYPERSENSITIVITY, VENTRIULAR ECTOPY IN PRESENCE OF BRADYCARDIA. AND SEVERE CONDUCTION ABNORMALITIES WITHOUT PACEMAKER AVAILABILITY.
DOSE 1.0-1.5 MG/KG IVP 2-3 MIN PRIOR TO RSI
DOSE: IV BOLUS 1.0-1.5 MG/KG OVER 3 MIN , REPEAT DOSE IS GIVEN IN 5-15 LATER AT HALF THE INITIAL DOSE. MAX 3MG/KG
PEDIATRIC DOSE: 0.5-1.0 MG/KG PER BOLUS WITH MAINT INFUSION OF 20-50 MCG/KG/MIN TITRATED TO EFFECT.

33
Q

tell me about atropine

A

AUTONOMIC cns AGENT, ANTICHOLINERGIC (PARASYMPATHOLYTIC) ANTIMUSCARINIC AGENT.

INHIBITS VAGAL TONE
PRIMARILY USED TO REMOVE EXCESS PARASYMPATHETIC TONE, AND TO BLUNT VAGAL TONE IN RSI.

USED IN HOSPICE TO DRY ORAL SECRETIONS ***

SIDE EFFECTS: PALPATATIONS, TACHYCARDIA, DRY MOUTH, DILATED PUPIS AND POSSIBLE ANXIETY.

DOSAGE: FOR SIGNIFICANT CARDOVASCULAR INSTABILITY 0.5-1.0 MG IVP q3-5 MIN (MAX DOSE 3 MG)

IF GIVEN ToO SLOW OR Too SMALL OF a DOSE CAN CAUSE PARADOXICAL SLOWING OF HEART RATE.**
