RDS In Neonate Flashcards
What are the signs of respiratory distress?
(Tachypnea + cyanosis)
Grunting, Nasal flaring, Chest retraction
What is the test that is most accurate and fast to differentiate cardiac vs respiratory causes of cyanosis
Hyperoxia test of oxygen more than 150 is respiratory cause
Othe differentiating factor for respiratory causes of cyanosis
History of: preterm, maternal fever, CS, Exam of: crackles, rhonchi, retraction, temp CXR: abnormal chest parynchema ECG: normal ABG: PCO2 increased
In which group of population isi transient tachypnea of the newborn is more common?
Respiratory distress type 2 is common in term, preterm and CS
What are the positive findings of TTN?
Wet lung and tachypnea
How is the outcome of TTN?
Starts 2hrs post delivery and resolves within 24hours
How to treat TTN?
Supportive and could give CPAP but no need for medics
What are the most important signs in tachypnea of the newborn?
- increased lung volume
- fluids filling the transverse fissures
Less:
- pulmonary congestion
- perihilar streaking
- cardiac boarder not clear
In a diabetic mother, which type of RDS is common to occur
RDS type 1
In CS mother, which type of RDS might occur
TTN
What is the cause of RDS 1
Surfactant deficency
How to manage RDS 1
CPAP\ventilaition and then surfactant
Differentiate between lung volume in RDS 1 and 2, and pneumonia
1: decreased lung volume
2: increased lung volume
3: normal lung volume
What are the x-ray findings of RDS1
1- ground glass appearance
2- air bronchogram
3- deecreased lung volume
4-bell shape (no pleural effusion)
In which parynchymal lung disease do we see the cardiac shadow very clear
Meconium aspiration
Pneumonia
What is the X-ray findings in meconium aspiration?
- Lung over inflation
- patchy density cloud like
- cardiac shadow
How to treat meconium aspiration?
Decrease lung pressure and NO
Mechonium aspiration is common in which age?
Post term
What are the pathogens that cause early pneumoina?
Step pneumonia HEmophillus GABHS Ecoli Klebsiell & chlymedia
What is early and late pneumon9oa
Early is less than 7 days
Late is more
In which group of population do we expect pneumonia to cause RDS
Preterm, PROM, maternal fever, term
How to treat pneumonia in neonate
1- AB
2- Vasopressor (dopamine or dobutamine)
3- O2 therapy & ventilator
What are the x-ray finding of pneumonia?
1- pleural effusion
2- see the heart
3- air bronchogrm’
4- granular appearance
What is the most common CDH??
Left side bochdaleck hernia
