Flashcards in pre term infant Deck (33)
1

fluid collection caused by pressure of presenting part of scalp against dilating cervix

caput succedaneum

2

day 2-5 common rash babies get

erythema toxicam

3

definition of pre term?

4

term?

37-42 weeks

5

post term

>42 weeks

6

risk factors?

polyhydramnios, cervical incompitence, drugs, alcohol, smoking, multiple pregnancy, placental abruption, infection, pneumonia, appendicitis, low BMI, low socioeconomic status

7

whats the difference?

get cold faster, don't breathe effectively, fragile lungs, fewer reserves. pulse oximetry often indicated

8

during cord clamping, pause for at least a minute to allow placental transfusion

lugs are more fragile

9

it is important to keep baby warm. heat them in plastic bag under heater

y

10

why is thermal regulation ineffective in pre term?

low BMR, minimal muscular activity, subcutaneous fat insulation negligible. High surface area to mass ratio

11

increased risk of nutritional compromise

limited nutrient reserves, immature metabolic pathways, increased nutrient demands

12

what is gestational correction?

adjusts plot of measurement to account for number of weeks a baby was born early

13

when should this be continued until?

1 year for infants born 32-36 weeks
2 years for infants born less than 32 weeks

14

neonatal sepsis. can be early (mainly due to bacteria acquired before and during delivery) or late onset - acquired after delivery (nosocomial or community sources)

y

15

causitive organisms of neonatal sepsis?

CONS, SA, strep pneumonaie, strep pyogenes, klebsiella, salmonella, pseudomonas, e coli

16

In In In

incubators increase infection

17

hyaline membrane disease. surfactant deficiency and structural immaturity - Respiratory Distress syndrome

2y pathology: alveolar damage, inflammation, formation of exudate from leaky capillaries

18

clinical features of RDS?

tachypnoea, grunting, intercostal recessions, nasal flaring, cyanosis

19

gets worse over?

minutes to hours

20

gradual worsening 2-4 days to..... then gradual improvement

management: maternal steroid and surfactant

21

premature infants at risk of patent ductus arteriosus

duct does not respond to close signals

22

oxygen requirements are high. exacerbates RDS. symptoms of CHF

.

23

interventricular haemorrhage?

form of inter cranial haemorrhage that occurs in pre term infants. begins with bleeding into the germinal matrix

24

risk factors? 2

prematurity and RDS

25

in 80% of cases, GMH leads to an ?

IVH

26

most IVH occur on ?

first day of life

27

preventative measures for IVH

antenatal steroids and prompt resus

28

most common neonatal surgical emergency?

necrotizing entercolitis

29

widespread necrosis in small and large intestine?

necrotising enterocolitis

30

there is a high incidence in?

pre term infants

31

typical presentation?

usually recovering from RDS, lethargy and gastric residuals, bloody stool, temp instability, apnea and bradycardia

32

can get retinopathy of prematurity 6-8 weeks after delivery

antenatal steroids and surfactant replacement has contributed to improved pre term care

33

what do you give to a mother expecting a per term birth to reduce risk of RDS?

surfactant and maternal steroid
