Q

What is the initial fluid bolus for treating shock?

A

20 ml/kg

Reassess after for need for repeat bolus

25
Why should blood glucose be monitored in critically ill children? Who is at greatest risk for hypoglycemia during shock?
Hypoglycemia is common during critical illness and can result in brain damage if untreated Infants, children with chronic illness at greatest risk for hypoglycemia during critical illness
26
Ddx of symptomatic bradycardia
HR < 60 with sx and signs of shock, respiratory distress or altered mental status Ddx - hypoxia - acidosis - hyper kalmia - hypothermia - heart block (AV block) - drugs and toxins (ccbs, opioids, digoxin, organophosphates )
27
Ddx of symptomatic bradycardia
HR < 60 and shock, respiratory distress, altered mental status Ddx - hypoxia - acidosis - hyperkalemia - hypothermia - heart block AV block - toxins/drugs - head trauma
28
How do you classify tachyarrhythmias?
1. Narrow complex - sinus tach - SVT - atrial flutter 2. Wide complex - VT
29
List some common and uncommon causes of sinus tachycardia
Common: exercise, pain, fever, anxiety, tissue hypoxia, hypovolemia (hemorrhage and non-hemorrhagic), shock, injury, toxins, poisons, drugs Uncommon causes: cardiac tamponade, tension pneumothorax, thromboembolism
30
What is the presentation of SVT in infants?
Usually goes unnoticed for long period of times so these kids often presents with sx/signs of congestive heart failure -irritability, poor feeding, increased work of breathing
31
What are the signs and symptoms of SVT in older kids?
- palpitations - SOB - chest pain - dizziness - light-headedness - syncope
32
What is the compressions: breaths ratio for 1 person CPR? 2 person CPR?
1 person: 30 compressions 2 breaths. (if in the field ok to just o compressions) 2 person: 15:2 (or if adolescent 30:2)
33
What are to meds you can give for symptomatic bradycardia?
1. Epi | 2. Atropine
34
What is the dose of epi to give IV/IO during a resuscitation? How long between doses? Max # of doses?
0.01 mg/kg or 0.1 ml/kg 1:10,000 concentration epi Give q3-5 mins No max # of doses really
35
What is a shockable rhythm?
Vfi. Or vtach
36
How many Jules of shock for defibrillation?
Initial: 2 j/kg Subsequent: 4 j/kg
37
What is PEA?
Electrical activity on the monitor but no pulse (so heart is not pumping)
38
What are the hallmarks of cardiac arrest?
1. Child unresponsive 2. Not breathing or only gasping 3. No pulse
39
What is the goal compression rate?
100 per min
40
What is different about rescue breathing when the patient is intubated?
1 breath per 6-8 seconds when compressions person is in recoil from a compression No longer the synchronized 15:2
41
What do you do if you find an unresponsive child?
1. Check for breathing 2. Check for pulses If no to both, shout for help, start CPR, give O2 and attach defibrillator
42
Initial rhythm on defibrillator is asystole. What do you do?
Start CPR (2 min) IV/iO access Epi q3-5 min Consider et intubation After 2 min recheck rhythm. Shock if vtach or vfib. Otherwise 2 more min CPR
43
What are the "Hs and Ts"
=reversible causes of cardiac arrest. H's: hypoxia, hypovolemia, hyperkalemia, hypoglycemia, hydrogen ions, hypothermia T's: toxins, trauma, tension pneumo, tamponade, thrombosis (PE or coronary)
44
What are the first 3 things to evaluate in a kid when you walk in the room?
1. Consciousness/mental status 2. Breathing 3. Color If yes to all 3 -> start primary evaluation If unresponsive/altered and not breathing -> shout for help and start CPR
45
What do you check on primary assessment?
1. Airway (speaking or crying, look for chest or belly movement, listen for breath sounds) 2. Breathing (RR, work of breathing, air movement, lung and airway sounds, O2 sat) 3. Circulation (HR, central pulses, peripheral pulses, cap refill, skin color and temp, BP) 4. Disability (level of consciousness, pupils, GCS) 5. Exposure (temp, bleeding, rashes)
46
What are some simple measures to open/maintain upper airway
1. Head tilt chin lift | 2. Suctioning (bulb or deep)
47
What can happen sometimes after you deep suction a kid?
Bonchospasm
48
When do you consider supplemental O2?
- if O2 sat < 94% on RA | - if O2sat < 90% on 100% O2, consider additional interventions
49
What is the AVPU scale?
Assesses responsiveness of child 1. Alert 2. Voice-responds only to voice 3. Pain-responds only to painful stimulus 4. Unresponsive
50
What do you do on secondary assessment?
1. Focused history (SAMPLE) 2. Focused physical exam Consider lab tests
51
What is your history on secondary assessment? (hint:sample)
``` S: signs and sx A: allergies M:medications P: past medical Hx L: last meal E: events ```
52
When do you do the primary assessment?
After initial assessment/look at the patient where you've determined they are responsive and breathing
53
What is cushings triad?
Hypertension Bradycardia Irregular breathing or apnea
54
How do you determine if you have adequate ventilation with PPV?
``` Visible chest rise with each breath O2 sat Exhaled CO2 HR BP Distal air entry Improvement in color ```
55
You think the child is not adequately ventilated (ie no chest rise). What are some things to troubleshoot?
1. Reposition the head (chin lift) 2. Verify mask size and good seal 3. Suction airway if needed 4. Check O2 source 5. Check ventilation bag and mask
56
Name 3 vagal maneuvers to try for compensated SVT
1. Bear down/blow through a straw 2. If less than 1year, rectal stim 3. Suction
57
Name 2 treatments for uncompensated SVT
Uncompensated= abnormal mental status, perfusion 1. Synchronized cardio version 2. Adenosine 0.1 ml/kg
58
Name 4 things to consider when not good chest rise or breath sounds after intubation.
DOPE D=displacement, check right side tube and right distance O= obstruction, mucus plug try suction P= pneumothorax E= equipment, seal, o2 hooked up,
59
How do you choose the right ET tube size?
Age+16/4 If less than 1 year, choose size 0
