Q

Roller Pumps:

3) Cons:
- Increased shear damage to RBCs,
- potential to delivery entrained air,
- risk of overpressurization (rupture of tubing)

3) place RUE SpO2, start PPV (start with RA, titrate supplemental O2 as needed), consider EKG
-if HR remains <100, or unable to attain goal SpO2 with PPV
4) Intubate, titrate FiO2 to goal SpO2
-If HR remains <100, or drops <60 at any time
5) Start chest compressions, intubate if not already done, and establish venous access (umbillical vein catheter or IO)
-If HR remains <60
6) IV epi (10mcg/kg) or tracheal epi (100mcg/kg), treat hypovolemia with NS or type O- blood, consider pneumothorax

48
Q

Factors affecting rate of inhalational induction? (3 +2)

A

1) Alveolar ventilation: as alveolar minute ventilation increases, rate of induction increases
2) Gradient partial pressure of inhalational agent: higher/larger gradient partial pressure = higher concentration of gas with each inhalation = more rapid induction
3) Blood:gas coefficient (Inverse relationship: lower blood:gas coefficient = less gas dissolved in blood = less gradient between inspired and alveolar concentrations = faster induction

4) Right to left shunt slows inhalational induction (can speed IV induction)
**Left to right shunt has minimal effects

51
Q

What is the difference between alpha-stat and pH-stat strategies?

A

Different strategies for managing CO2 in the hypothermic patient (bypass, etc.)

  • Alpha-stat: Does NOT add CO2 to the circuit/patient. Allows pH and PCO2 to change with hypothermia (PCO2 decreases, pH increases, blood flow to brain decreases).
    *Maintains electrochemical neutrality
  • pH-stat adds CO2 to the oxygenator/circuit, with goal to maintain PaCO2 at 40 mmHg and pH at 7.40. (This maintains blood flow to brain)
52
Q

Alpha-stat vs. pH-stat:
Which strategy is better in adults?
Why?

A

Alpha-stat is recommended for adults undergoing MODERATE hypothermia –> leads to improved neurologic outcomes.
- Primary mechanism of brain injury in adults is embolic events, so improved cerebral blood flow a/w pH-stat may be more harmful for adults.

*For adults undergoing DEEP hypothermia, best strategy is unknown

53
Q

Alpha-stat vs. pH-stat:
Which strategy is better in pediatrics?
Why?

A

pH stat is preferred in children.
It provides superior brain protection
- Primary mechanism of neurologic injury in peds is thought to be related to ischemia, so increased cerebral blood flow a/w pH strategy helps to reduce risk of ischemia.

A
  1. maintain preload and forward systemic flow
  2. judiciously reduce afterload (to encourage forward flow)
  3. Maintain HR in the high-normal range (80-100BPM) - decreases time for regurg to occur

68
Q

Anesthetic goals for patients with mitral regurgitation due to mitral valve prolapse (MVP)? (5)

A

General: avoid reducing preload, avoid LV emptying, which can worsen prolapse and MR

  1. Avoid sympathetic activation (catecholamines increase HR and contractility)
  2. Maintain SVR
  3. Maintain Preload
  4. Avoid increased myocardial contractility (which causes more LV emptying)
  5. Avoid tachycardia (need more time for adequate LV filling)
69
Q

Omphalocele vs. Gastroschisis:

How are they similar? (3)

A
  • Both congenital disorders
  • Both more likely in Males
  • Characterized by abdominal wall defects that allow for EXTERNAL HERNIATION OF ABDOMINAL CONTENTS
70
Q

Omphalocele vs. Gastroschisis:

How are they Different? (4)

A
  1. Omphalocele occurs at base of umbilicus, gastroschisis usually occurs LATERAL to the umbilicus
  2. Omphalocele has membranous covering around abdominal contents, gastroschisis has no membranous covering, so contents are exposed to environment and have increase risk of infection and loss of fluid
  3. Omphalocele usually involved functioning bowels, gastroscisis usually involves inflammed, non-functional bowel
  4. Omphalocele is associated with congenital anomalies (esp. cardiac, diaphragmatic hernia, trisomy 21, etc.), gastroscisis is less likely to be associated with congenital anomalies.

Q

Aspiration:

3) what are other changes that can develop? (4)
4) how long should you monitor someone with aspiration?

A

1) a chemical pneumonitis characterized by hypoxemia, bronchospasm, and atelectasis
2) earliest change is intrapulmonary shunting
3) other changes include pulm edema, pulm hypertension, and hypercapnea and hypoxia.
4) monitor for 24-48 hours

90
Q

Treatment steps for aspiration? (9)

A
  1. Head down position
  2. Add air to cuff if ETT or trached
  3. Suction
  4. Ventilate with 100% O2 as needed
  5. bronch to remove particulate material/collect sample of tracheal aspirate for cultures
  6. Apply PEEP (after suctioning so you don’t force aspirate further down lungs)
  7. Insert OG/NG to suction stomach
  8. Order baseline CXR and ABG
  9. Monitor for 24-48 hours for development of symptoms
  • NO evidence for prophylactic antibiotics or steroids
