4
Q
Volume Expansion DR: Indications

- Subarachnoid - rupture veins subarachnoid space or small leptomeningeal vessels
- Epidural - rupture middle meningeal artery
- IVH
9
Q
ICH: Risk Factors
A
- Instrumentaiton
10
Q
ICH: s/s
A
- Apnea
- Seizures
- Resp depression
- Altered tone
- Decrease LOC
- Increase irritability
11
Q
ICH: MGMT
A
- Common no urgent mgmt DR
- s/s + instrumentation →
- CUS asap
- Definitive study
- CT
- MRI
12
Q
Extracranial Injuries: Types
A
- Caput succedaneum
- Cephalohematoma
- Subgaleal hemorrhage - rupture veins subgaleal space (between skull periosteum and epicranial aponeurosis)
13
Q
Subgaleal Hemorrhage: Patho
A
- Hemorrhage under aponeurosis
- Traction scalp during delivery → shearing or severing emissary veins in subgaleal space
- Extends from orbital ridges to nape of neck
- 20-40% sequestration blood volume pos
14
Q
Subgaleal Hemorrhage: Risk Factors
A
- Instrumentation (esp vacuum)
- Vacuum cup marks
- Over sagittal suture
- <3cm anterior fontanel
- Nulliparity
- APGAR <8 5min
15
Q
Subgaleal Hemorrhage: s/s
A
- Fluctuant swelling
- Crosses suture lines
- Poorly defined edges
- Anteriorly displaced ears
- Pallor
- Hypotonic
16
Q
Subgaleal Hemorrhage: Complicaitons
A
- Mortality 10-15%
- Hypovolemic shock
- Consumptive coagulopathy (esp large bleed)
- Hyperbili
17
Q
Subgaleal Hemorrhage: MGMT
A
- Suspect w s/s (esp w instrument delivery)
- NICU NOT DR mgmt
- VS q1-4hr
- Serial FOC measurements
- Serial hct
- UVC w s/s ongoing blood loss
- Coag studies - rt risk consumptive coagulopathy w large bleeds
- Transfusion PRN coagulopathy
- FFP
- Cryoprecipitate
- Platelets
- Massive subgaleal hemorrhage - pos recombinant activated factor VII
18
Q
Subgaleal Hemorrhage: DX
A
- CUS - rapid assessment
- CT/MRI - definitive f/u
19
Q
Nerve Palsies: Types RT Birth Trauma
A
- Facial nerve palsy
- Brachial plexus palsy
- Phrenic nerve palsy
20
Q
Phrenic Nerve Palsy: Incidence
A
- 1:15,000 live births
- 80% unilateral (esp R side)
21
Q
Phrenic Nerve Palsy: Patho
A
- Phrenic nerve - originates anterior rami C3-C5, descends thorax, innervate diaphragm
- Source motor innervation diaphragm - contract w inspiration, dome shape exhalation
- Extreme lateral flexion and traction neck → injury
22
Q
Phrenic Nerve Palsy: Risk Factors
A
- Shoulder dystocia (hightest risk)
- Macrosoma
- Instrumented
- Vag breech
23
Q
Phrenic Nerve Palsy: Complications
A
- Mortality 10-15%
- Sig respiratory distress
- Diaphragmatic paralysis (esp w brachial plexus injury)
- Low Apgar
24
Q
Diaphragmatic Paralysis: s/s
A
- Paradoxical (see-saw breathing)
- Tachypnea
- Cyanosis soon after delivery
25
Q
Phrenic Nerve Palsy: MGMT
A
- Sig respiratory distress - DR ER
- Consider w acute resp distress birth (esp w shoulder dystocia, brachial plexus injury, other risk factors)
- Plication diaphragm - if cannot wean resp support
