Effects:
CV: elevated BP
Hematology: plasma volume contraction = increase Hct, risk of hypovolemic shock in event of hemorrhage

22
Q

Rx/ Management

Signs: monitor maternal BP and fundal height

  • Another maternal BP w/ NST visit
  • Urine protein w/ each visit - gestational HTN PT
  • Abnormal FH NON-REACTIVE NST = BPP

Rx management for: Preeclampsia w/ No severe features or ONLY gestational HTN
(htn dz of pregnancy)

23
Q

Rx. management

25
Q

Types of opioids: heroin, opium, morphine, fentanyl, oxycodone HCL , hydrocodone, oxymorphone, meperide, propoxyphene

A

Opioid addiction

26
Q

Screening tool example

  • CRAFFT (car, rest, alone, friends, family, trouble)
    1. Begin asks if they had alcohol, pot/hashish, or anything else to get high in past 12 months
    • If say yes to one, ask all from part B
    • If say no to all, only ask the 1st part B question
  1. Have you ever ridden in a CAR driven by someone who was high or had been using drugs or ethod?
    RAFFT
A

Opioid addiction screening told

27
Q

H&P

  1. Seek PN care late in pregnancy
  2. High non-compliance with appointments
  3. Poor wt gain
  4. Seem intoxicated or sedated
  5. Track marks, skin abscess

-Withdrawal syndrome w/ physical dependence
Fetus at risk for IUGR, preterm labor, placental abruption, death

Labs: CBC, STD,HIV, Hep C w Hep B w/ IVDU or high risk exposure, urine drug screen

A

Opioid Addiction h&p

28
Q

Psychosocial intervention
Detox - highly motivated pt, special detox center - perinatal addiction

Detox recommended during 2nd trimester to avoid risk of miscarriage OR after 32 weeks EGA to limit preterm labor risk

A

Opioid addiction rx management

29
Q

Methadone maintenance

  • registered abuse tx specialist
  • substance abuse and mental health services admin
  • -> pn care, family counsel, rehab/dependency , nutrition, psychosocial services

Buprenorphine maintenance

  • physicians office, w PN visits
  • S/L, implant
A

RX management for opioid addiction

30
Q

Interdisciplinary team- all work together

  • Fetal monitoring : NSTs or BPP 4-6 hours after methadone dose
  • -> Methadone decreases baseline FHR, breathing movement and tone

Post partum : refer patient back to treatment center for maintenance therapy counseling, breast feeding encouraged, methadone minimally excreted in breast milk

A

Rx management for opioid addiction

31
Q

NAS: neonatal abstinence syndrome

  • cns/ans hyperactivity, poor feeding/uncoordinated sucking reflex, irritable, high pitch cry
  • sx within 72 hours delivery and may last days to week
A

opioid addiction rx management

32
Q

Jaundice - most common cause is ACUTE VIRAL HEPATITIS
DDX - jaundice = hepatic, obstructive gall bladder or bile duct dz, severe preeclampsia, HELLP syndrome
