Postpartum adaptations and nursing mgmt Flashcards
Puerperium period
-Begins after delivery of placenta and lasts 6 weeks
-Called 4th trimester
-True postpartum period lasts 9-12 months after birth
Maternal physiologic adaptations: reproductive system
-Menstrual cycles returns
-Breastfeeding is not a safe contraceptive
-Uterus returns to prepregnancy size via involution
-Breasts don’t return to prepregnant size
Maternal physiologic adaptations: uterine involution
-Uterus returns to normal size via involution
-By 3 days, fundus lies btwn 2-3 fingerbreadths below umbilicus
-By end of 10 days, fundus can’t be palpated
-If these changes don’t occur, subinvolution occurs (delayed or absent involution)
-Uterine involution occurs d/t complete expulsion of amniotic membranes and placenta at birth, complication-free labor, breast-feeding, early ambulation
-Subinvolution occurs d/t full bladder, anesthesia, overdistention of uterine muscles, close childbirth spacing
Maternal physiologic adaptations: lochia
-Lochia is vaginal discharge that occurs after birth and lasts for 4-8 weeks
-Results from involution
-Lochia rubra: deep-red mixture of mucus, tissue-debris, and blood that occurs 3-4 days after birth
-Lochia serosa: pinkish brown, expelled 3-10 days after, mostly leukocytes, RBCs, and serous fluid
-Lochia alba: creamy white or light brown, 10-14 days after, consists of leukocytes, tissue, fluid content
-At any stage should have a fleshy smell, an offensive odor usually indicates infection such as endometritis
-A danger sign is reappearance of bright-red blood after lochia rubra has stopped
Maternal physiologic adaptations: afterpains
-Uterus contractions prevents hemorrhage from placental site
-Called afterpains
-More common in multiparous and breastfeeding women
-Usually respond to oral analgesics
-Stronger during breastfeeding bc oxytocin released by sucking reflex strengthen contractions
Maternal physiologic adaptations: cervix
-Cervix is partly dilated, bruised, and edematous
-Never regains prepregnant state
-External cervical os is no longer shaped like a cervical but as a jagged slit-like opening (similar to a fish mouth)
Maternal physiologic adaptations: vagina
-Mucosa thickens and rugae returns after hormone production resumes
-Will always remain a bit larger than it had before
-Dryness and coital discomfort (dyspareunia) plague women until menstruation returns
Maternal physiologic adaptations: perineum
-Edematous and bruised
-Muscle tone may not return
-Swollen hemorrhoids
-Encourage women to practice pelvic floor muscle training exercises
-Failure to maintain perineal muscle tone can lead to urinary incontinence later in life
Maternal physiologic adaptations: CV system
-Heart is displaced up and to left during pregnancy
-Output remains high then declines
-Blood volume drops
-Acute decrease in Hct indicates hemorrhage
-Common for temp to be 100.4+ in 24 hrs d/t mild dehydration, slight decrease in BP can occur
-Preeclampsia may occur
Maternal physiologic adaptations: pulse and bp
-Bradycardia, low BP
-Investigate tachycardia and prolonged HTN
-Prolonged decreased BP can suggest infection or hemorrhage
Maternal physiologic adaptations: coagulation
-Cells favor coagulation to reduce blood loss
-Clotting factors increased
-RIsk for thromboembolism
Maternal physiologic adaptations: blood cellular components
-Hgb and Hct slightly decrease
-WBC is elevated
Maternal physiologic adaptations: urinary system
-Bladder tone and size returns
-Anesthesia can make it difficult to feel sensation to void
-Bladder distention can cause uterus to displace from midline to the right –> risk of hemorrhage
-Urinary retention is major cause of uterine atony (allows excessive bleeding)
-Diuresis
Maternal physiologic adaptations: GI system
-Decreased bowel tone and peristalsis
-Stool softener needed
-Most women hungry and thirsty d/t NPO restrictions and energy expended uring labor
Maternal physiologic adaptations: musculoskeletal system
-Return of joint states
-Permanent increase in shoe size
-Hip and joint pain
-Loss in muscle tone and separation of longitudinal muscles (rectus abdominis muscles)
-Separation of rectus abdominis muscles (diastasis recti)
-If rectus muscle tone is not regained thru exercise, support may not be adequate for future pregnancies
Maternal physiologic adaptations: integumentary system
-Linea nigra and melasma fade
-Hair loss
-Striae gravidarum (stretch marks) fade to silvery lines
-Profuse diaphoresis
Maternal physiologic adaptations: respiratory system
-16-24 breaths per min
-SOB and rib aches are resolved
-Resolves within 1-3 weeks
Maternal physiologic adaptations: endocrine system
-Rapid clearance of placenta hormones
-Estrogen low until breastfeeding frequency decreases
-hCG, hPL, and progesterone decline
-Prolactin levels depend if breastfeeding or not (present if yes)
Maternal physiologic adaptations: weight loss
-Lactation not sufficient enough to lose weight
-Rate of weight loss d/t lifestyle factors
Maternal physiologic adaptations: sexual health
-Painful intercourse
-Effects on relationships, mood, and sexual health
Maternal physiologic adaptations: lactation
-Appears 4-5 days after birth
-Estrogen stimulates growth of milk collection system while progesterone stimulates growth of milk production system
-Progesterone triggers secretion of milk
-Oxytocin causes ejection of milk
-Milk production will subside if mother is not breastfeeding
-Breast crawl: infant moves up from abdomen to breast
-Let down reflex: tingling sensation in both breasts before or after breastfeeding
-Engorgement: swelling of breast tissues as precursor to lactation, from infrequent feeding, stand in warm shower or apply warm compresses before feeding, cabbage leaf compresses, breast massage, breast pumping
Maternal physiologic adaptations: suppressing lactation
-Tight, supportive bra 24 hrs daily
-Ice to breasts
-Avoid sexual stimulation
-Avoid exposing breasts to warmth
Maternal physiologic adaptations: ovulation and menstruation
-Estrogen drops significantly at birth
-Progesterone quiets uterus to prevent preterm birth
-Oxytocin stimulates breastfeeding
-Prolactin present in breastfeeding women
-Nonlactating women: menstruation resumes in 7-9 weeks
-Lactating women: menstruation resumes in 3 months
-Ovulation may occur before menstruation, therefor breastfeeding is not contraception unless mother exclusively breastfeeds, has had no period since giving birth, and infant < 6 m
Cultural considerations: balance of hot and cold
-Viet women view postpartum period as cold state (duong) and protect themselves from warmth
-Practices: warm water for hygiene and stimulation of lactation, consuming warm foods, staying indoors
-Chinese women view postpartum period as states that disturb yin and yang
-Practices: physical activity, maintenance of body warmth, certain food consumption
-Many cultures believe loss of blood is hot, postpartum period is cold, and mother must balance that w/ intake of hot foods
-Cold foods such as fruits and veggies should be avoided
-Present in Latin American, African, and Asian cultures
