Q

Hypoplastic left heart syndrome mgmt and goals of care

A

initial mgmt is aimed ensuring sufficient mixing of oxygenated and deoxygenated blood and optimizing ventricular function via PDA

  1. prostaglandin E1 0.01-0.05mcg/kg/min
  2. avoid supplemental oxygen if able
  3. Consider dobutamine/milirone to reduce SVR
  4. allow a mild resp acidosis and avoid supplemental oxygenation in order to allow SVR BF. Acidosis and hypoxia causes pulmonary vasoconstriction.
  5. the initial goal of therapy is to balance PVR and SVR as BF will always take the course of least resistance.

Q

Hyperbilirubinema pathophysiology and treatments

A

Unconjugated bilirubin is a waste product of hemoglobin breakdown that is taken up by the liver, where its converted to conjugated bilirubin.

Conjugated bilirubin is water-soluble and is excreted into the bile to be cleared from the body.

Bilirubin is a product of heme catabolism. The enzyme heme oxygenase located in all nucleated cells, catalyze the breakdown of heme, resulting in the formation biliverdin. Biliverdin then rapidly converts to Hb.

primary concern would be BIND/karnectus.

  1. use the bilitool to gage treatment threshold
  2. phototherapy
  3. go up on TFI by 20%
  4. exchange transfusion, IVIG.

43
Q

Indications for high-flow oxygen

A

Oxygenation not met by low-flow N/C.
Any elevated WOB without signs of failure.
Respiratory secretions causing increased WOB.

44
Q

How does high flow improve ventilation

A

§ Promotes airway patency
§ Creates nitrogen washout, which improves diffusion of CO2 washout and increases oxygenation diffusion.
§ CO2 elimination is improved with a higher PAO2 because of the displacement of CO2, increasing the gradient between PaCO2 and PACO2, improving diffusion and ultimately elimination. There is less of an effect on CO2 elimination compared to minute ventilation
Reduces sticky secretions/pugs

45

A 
neo = <10kg
peds = 10-20kg
adults = >20kg
46
Q

A

0.35-0.45

47
Q

Normal iTIME for peds

A

0.8

48

A

large spikes in pressure (cough, plugs)

49
Q

The white line, on the Hamilton t1, is always set to 10CMH20 below the high PIP limit, why?

A

because it is the max pressure that the vent will apply in (S)CMV+, which is PRVC

50
Q 
List how thermal regulation is maintained in an incubator in regards to:
conduction
convection
radiation
evaporation
A

○ Conduction – thermal pad matches infants temperature
○ Convection – barrier to air prevents conection loss
○ Radiation – incubator cover prevents sunlight penetration
Evaporation – prevention of heat loss environmental box

51
Q

Indications and why to close a PDA

A

Moderate to large PDA’s
- PDA closure is recommended for patients with moderate to large PDAs associated with symptoms of left-right shunting, clinical evidence of volume overload or reversible pulmonary arterial hypertension.

-Closure results in resolution of symptoms and a decrease in the likelihood of severity of PAH and the development of irreversible pulmonary vascular disease (Esinmenger syndrome)

52
Q

Management of placental abruption complicated by PTL <34 weeks

A

C-Section if unstable.

If stable mom and reassuring fetal status <34 weeks
- PTL = Tocolytics for 48 hours, betamathasone

When the fetus and mother are both stable and there is no evidence of major bleeding/coagulopathy, conservative mgmt with the aim of delivering a more mature fetus.

53
Q

Placental Abruption mgmt of 34-36 weeks.

A

We deliver most patients with acute abruption at 34+0 to 36+6 GA since patient’s remains at risk of maternal or fetal compromise from progressive placental abruption and neonatal morbidity is relative low at this GA

54
Q

Placental abruption at 36w to term mgmt

A

deliver all pregnancies with suspected acute abruptions

55
Q

Eclampsia key principals of management revolve around

A

Prevention of maternal hypoxia and trauma
treatment of severe HTN if present
Prevention of reoccurring seizures
Evaluation of prompt delivery

56
Q

Drug of choice for prevention of recurrent seizures in the setting of Eclampsia

A

Magnesium Sulfate is the anti seizure medication of choice.

Treatment is primarily directed at prevention of recurrent seizures rather than control of the initial seizure since the initial seizure is usually short duration and may occur in a setting where IV access or drugs are not readily available.

57
