25
How long is the postpartum phase
Traditionally, 6 weeks
26
Lochia assessment
Color, amount (scant, light, moderate, heavy, excessive), consistency Scant:less than 2.5 cm Light: 2.5-10cm Moderate:more than 10 cm Heavy: one pad saturated within 2 hr Excessive: one pad saturated in 15 min or less, pooling of blood under buttocks
27
Lochia rubra
dar red color, bloody consistency, flesh odor, small clots -transient flow inc during BF(inc oxytocin, inc uterine contraction=inc bleeding) and upon rising -1-3 days post delivery
28
Lochia serosa
Pinkish brown, serosanguinous, small clots and leukocytes -day 4-days after delivery
29
Lochia alba
Yellowish white creamy color, flesh odor, can consist of icons and leukocytes -approx. day 10 up to 8 weeks postpartum
30
Complications of meconium stained amniotic fluid and why does it happen
31
Newborn skin-acrocyanosis
Normal, blue/purple hands and feet
32
Newborn skin- milia
Look like white pimples on face, go away on own-dont pop
33
Newborn skin-Mongolian spots
More common on darker skin, commonly on buttocks
34
Newborn skin-vernix
“Cheesy” coating from the womb
35
Caput vs cephalohematoma
Caput succedaneum does cross suture lines and a cephalohematoma does not -Caput=scalp edema over occiput -Ceph=blood between skull and periosteum, can cause hyperbilirubinemia (inc RBC from bleeding)
36
RDS
respiratory distress syndrome
37
Why RDS happens in newborns
Result of surfactant deficiency with poor gas exchange and ventilatory failure -surfactant=aid to alveoli expansion, keeps form collapsing -atelectasis=inc WOB
38
Risk factors RDS
-Preterm gestation -Perinatal asphyxia(meconium staining, cord prolapse, unchallenged cord) -maternal DM - PROM -maternal use of barbiturates/narcotics -C section w/o labor -hypovolemia -genetics: white males
39
S/S RDS
Tachypnea (>60) Nasal flaring -expiratory grunting -retractions -labored breathing with prolonged expiration -fine crackles -cyanosis
40
Meds given for RDS
Surfactant -<27-30 weeks=intubate and round of surfactant then ideally extubate -resp assess before and after -suction prior -assess endotracheal tube placement(listen RR) -avoid suctioning of endotracheal tube for 1 hr after admin (if ET tube staying in)
41
Actions immediately following birth for mother and infant
Baby is dried off and warmed up, bulb suctioning, stimulate baby to breathe, 1 min and 5 min APGAR scoring -mother delivers placenta, ensure no fragments retained -skin to skin
42
Postpartum hemorrhage medications
Oxytocin, methergine, misoprostol, carboprost
43
PPH-methergine
Uterine stimulant -controls postpartum hemorrhage -assess uterine tone and vaginal bleeding -DO NOT admin to clients with HTN
44
PPH-misoprostol
Cytotec (Also used for cervical ripening-topical) -controls hemorrhage -assess uterine tone and vaginal bleeding -tablets
45
PPH meds-carboprost
Hemabate (makes clients feel nasty) -uterine stimulant Controls hemmorhage -assess uterine tone and vaginal bleeding
46
Postpartum hemorrhage med side effects-Carboprost
Fever, HTN, chills, HA, N/V, diarrhea(most common)
47
Postpartum hemorrhage med side effects-Methergine
HTN, N/V, HA
48
PPH-oxytocin
Uterine stimulant, promotes uterine contractions -assess uterine tone and vaginal bleeding
49
Postpartum hemorrhage med side effects-oxytocin
Water intoxication (lightheadedness, N/V, HA, malaise) -rxns can progress to cerebral edema with seizures, coma, death -hypertonic uterus
50
Postpartum hemorrhage contraindication for meds-methergine
DO NOT ADMIN TO CLIENTS WITH HTN
51
What medication is given to Rh- mothers of Rh+ infants
Rho-gam immunoglobulin
52
How do we determine infant is getting enough input?
Voiding patterns
53
Newborn reflexes
Moro, tonic neck (fencing), stepping/walking, sucking and rooting, swallowing, babinski, pull-to-sit, planar grasp, plantar grasp
54
Moro reflex
“Startle reflex” symmetric abduction and Extension of arms and splayed fingers followed by flextion of limbs, slight tremor may be noted
55
Tonic neck(fencing) reflex
When head turned to side, same side arm and leg extended and opposite limbs flexed into body
56
Babinski reflex
Stroke baby foot from heel to toes on lateral side of foot -big toe dorsiflexes and other toes splay out and “fan”
57
Plantar grasp
Finger on baby’s foot and baby grasps fingers/wraps fingers around
58
Palmar grasp
Finger in baby’s palm and baby wraps fingers around
59
Sucking reflex
Finger on roof of mouth (hard palate) and baby suckles
60
Rooting/latching reflex
Touch lip or cheek and baby turns head to stimulus and attempts to suckle
61
Which reflex assists with latching?
Rooting and sucking
62
SGA
Below 10th percentile Small for gestational age
63
LGA
Large for gestational age Above 90th percentile
64
What do we monitor for in SGA
Respiratory distress, temperature instability, feeding difficulties, hyperbilirubinemia New Ballard score
65
What do we monitor for in LGA
Respiratory distress, temperature instability, feeding difficulties, hyperbilirubinemia -new Ballard score
66
What actions to take for a postpartum hemorrhage
Massage fundus until firm -monitor amount of blood/cots coming out with massage -admin meds -check tone of fundus and position r/t umbilicus
67
Instructions for bulb syringe
“M then N” Suction mouth first then the nose -depress bulb outside of mouth/nose and insert and release to apply suction -squeeze contents out off to the side after before depressing bulb again for reinsertion
68
Ballard score
Assesses neuromuscular and physical maturity, estimation of gestational age by maturity rating
69
What is Ballard score used for
Comparing actual gestational age and the Ballard score= tracking to see if actual neuromuscular and physical maturity is on par for gestational age (are they where they need to be?
70
S/S NB sepsis
71
TORCH
Complex of infection types in newborns
72
TORCH infections
Toxoplasmosis, other infections, rubella, cytomegalovirus, and herpes simplex virus
73
Toxoplasmosis
R/F: consuming raw meat, handling cat feces, manifestations similar to influenza
74
Other infections- TORCH
Hep A and B, HIV, parvovirus, syphilis, mumps, varicella-zoster
75
Rubella-TORCH
Check immunity-pregnant healthcare workers should avoid R/F: contracted through children who have rashes or neonates who are born to pts who had rubella during
76
Cytomegalovirus
Member of herpes virus family R/F: 1. transmitted by droplet from person-person, through semen, cervical and vag secretions, breast milk, urine, blood 2.latent virus can be reactivated and cause disease in utero or during vaginal birth
77
Herpes simplex virus
Anti-viral prophylaxis, if not high fatality R/F: direct contact with oral or genital lesions Transmission to fetus is greatest during vaginal birth w/active lesions
