Back to the Basics! | Fetal Heart Tracing | Anesthesia | Stages of Labor | Labor Augmentation |
---|---|---|---|---|
FIRST!!
She states she has been having regular contractions every 5 minutes and some blood tinged mucous. In the office last week she was 2 cm. You check her cervix and she is now 4 cm, 50%, soft, anterior, -2 station.
What stage is she in? |
110-160
minimum of 2 minutes in any 10 min segment
What is defined as a normal fetal heart rate?
How is baseline determined on EFM? |
parental agents, epidural, spinal, general, pudendal blocks
Types of anesthesia available
|
Onset of labor (regular painful ctx q3-5min) to complete dilation. Latent phase - up to 4cm - Active phase - 4cm to complete.
Define the first stage of labor?
What are the 2 phases? |
E1, 25mcg PV q 4hrs (ususally ~6doses), onset of 30 minutes, no no in VBAC!
MISOPROSTOL
What type of prostaglandin is it? What is the dosing? How fast does it work? |
5 or less
A Bishops score of ____ suggests that labor is unlikely to start without an induction.
|
absent: undetectable
minimal:5 or less moderate: 6-25 marked: >25
Define Absent/Minimal/Moderate/Marked variability
|
Demerol 25-50mg IV q1-2hr
Demerol 50-100mg IM q2-4hr Morphine 2-5mg IV or 10mg IM q4hr Phenergan 25mg IV
parental agents for labor pain
|
nulliparous = >20hrs
multip = >14hrs
What is considered a PROLONGED latent phase?
|
E2, 10mg, usually ~12hrs, per manufacturer: not to start Pit for 6hrs after removal
CERVIDIL
What type of prostaglandin is it? What is the dosing? How long does it stay in? |
RESUSITATE! position change, oxygen to increase maternal-fetal O2 gradient, IVF bolus to corrent hypotension, discontinue PIT, SVE
You review a pts strip and notice late decelerations, what do you do?
|
early: head compression, mirrors ctx and onset to nadir >/=30sec, common in active labor 4-7cm
late: gradual decrease with onset to nadir >/=30sec, nadir after peak of ctx variable: abrupt decrease, drop 15bts for 15sec but no more than 2 minutes
Define early, late, variable deceleration
|
epidural routine if plt >100,000
contraindicated if less than 50,000
anesthesia and thrombocytopenia
|
1.2cm/hr for nulliparous
1.5 cm/hr for multiparous PROTRACTION DISORDER
What is the rate of cervical dilation in the active phase of labor for nullip vs multip?
What is the diagnosis if cervical change is less? |
E2
PREPIDIL
|
Engagement, descent, flexion, internal rotation, extension, external rotation, expulsion
What are the Cardinal movements?
|
baseline110-160
variability: moderate late/variables: absent early: present or absent
define a Cat 1 tracing
|
therapeutic Lovenox stop >24hrs
prophylactic Lovenox stop >12hrs heparin :6hrs
anesthesia and anticoagulation
|
complete dilation to delivery of infant
nullip: <3hr with epidural, <2hr multip: <2hr with epidural, <1hr without
Define the 2nd stage of labor? How long should it take for nullip vs multip with and without an epidural?
|
Cook catheter, laminaria
Options for mechanical dilation
|
1500
In what year was the first successful cesarean section (with mother and baby both surviving)
|
absent variability in the setting of recurrent lates, variables or bradycardia OR sinusoidal pattern
define a Cat 3 tracing
|
post-dural puncture headache - IVF, caffeine, blood pathch (inject 20-30cc of the pts own blood into the epidural space)
what is the most common pp complaint following epidural anesthesia
|
delivery of placenta, <30minutes
cord lengthening, gush of blood, fundal rebound
Define the 3rd stage of labor?
Signs of cord separation? |
