Q

if pt comes in with tongue hanging out, drooling, fever, cyanosis what should you do

A

is an emergency pt needs to go to OR immediately; contact ENT and airway will be handled in the OR (most likely tracheotomy)

Q

what are some of the challenges with masking in pediatrics

A
  1. finger placement - easy for finger to move from mandible and into submental triangle –> occlusion 2. larger the tongue the harder to bag 3. you need a seal bc the INH agent is on 4. very challenging with babies

Q

if you are using an OPA on induction, when would be the best time to place it

A

Q

ETT depth for 1 year old

25
ETT depth for 2 year old
12 cm
26
ETT depth for child > 2 years of age
12 + age/2
27
T/F: awake tracheal intubations are common in peds
FALSE
28
size of ETT in pt weighing less than 1 kg 1. cuffed ____________ 2. uncuffed ___________
1. cuffed - N/A 2. uncuffed = 2 - 2.5 mm
29
size of ETT in 1-2.5 kg pt 1. cuffed = __________ 2. uncuffed = ____________
1. cuffed = N/A 2. uncuffed = 2.5 - 3.0
30
size of ETT in neonate - 6 mo old 1. cuffed = ____________ 2. uncuffed = ____________
1. cuffed = 3 2. uncuffed = 3 - 3.5
31
size of ETT in 6 mo - 18 mo old 1. cuffed = _____________ 2. uncuffed = _______________
1. cuffed = 3.5 2. uncuffed = 4
32
size ETT in 18 mo - 2 year old 1. cuffed = ______________ 2. uncuffed = ____________
1. cuffed = 4 2. uncuffed = 4.5
33
formula for size of uncuffed ETT in children > 2 years of age
(age + 16)/4
34
formula for size of cuffed ETT in children > 2 years of age
[(age + 16)/4] - 1/2 size
35
what is the disadvantage of straight laryngoscope blades for peds
they can injure the epiglottis
36
what was the theory behind using uncuffed ETT in children < 8 years of age
had decreased pressure on internal cricoid cartilage, thus caused less mucosal damage and decreased risk of post-extubation croup
37
disadvantages to uncuffed ETT
1. increased risk of repeated DL d/t incorrect sizing --> edema 2. leak --> wase of INH agent 3. changes in surgery dynamic (peritoneal insufflation) may drastically change leak status 4. paralysis can lead to greater relaxation and increased leak
38
all cuffed ETTs in todays time are ____________ volume ___________ pressure
higher; lower
39
what is a risk of prolonged intubation with cuffed ETT, esp in pre-term neonates
acquired subglottic stenosis
40
what is the pathogenesis of acquired subglottic stenosis
there is ischemic injury to lateral wall pressure from ETT --> edema and narrowing of subglottic area
41
advantages to cuffed ETT in peds
1. less DL 2. better seal, which can be changed through the case if needed 3. decreased risk of aspiration
42
typically you would go down __________ size from uncuffed for a cuffed ETT
2-Jan
43
if you have placed a cuffed ETT, and are using N2O for the case, what should you be cautious of?
if long case, N2O can cause the cuff to expand --> so check cuff pressures
44
advantage of LMA
1. frees up providers hands 2. less room pollution 3. can use with vent 4. can pull deep or awake 5. great for children at risk for bronchial airway reactivity
45
why should LMA still be cautioned in children with recent URI
because risk for laryngospasm is still so high
46
what is the estimated blood volume in a preterm infant
100 mL/kg
47
what is the estimated blood volume in a term infant
90 mL/kg
48
what is the estimated blood volume in an infant
80 mL/kg
49
what is the estimated blood volume in school aged child
70-75 mL/kg
50
what is the estimated blood volume in an adult
70 mL/kg
