-
Classifying a Woman's Pregnancy Hx
- G - Gravida - total # of Pregnancies
- P - Para - # of babies Born at 20 or > weeks
- TPAL or FPAL
-
Intrapartum - period during which labor & deliver take place
- The Nurse collects ASSESSMENT DATA
- The Cervic will AFFACE within an hour - TRUE LABOR
-
Onset of Labor
- Contractions begins with Irregular uterine - more INTENSE DURING WALKING - - starts on back & radiate to the front
- Rupture of Membranes - when did it ruptures
- CHECK V/S & FETAL HR
- Rupture > 24 hrs before delivery ->infection
-
Assessment of Amniotic Fluid
- Nitrazine Paper
- BLUE - amniotic fluid
- YELLOW - URINE
- Fernlike - when amniotic fluid is placed on a glass - IT LOOK LIKE FERN IN MICROSPCOPE
-
Five Factors affecting Labor & Birth
- Passenger - the Fetus & the placenta
- Fetal Flexion - chin flexed to chest
- Fetal Extension - chin extended away from chest
- OCCIPUT - back of the head enters first
- Station 0 - at the level of Imaginary line - OF THE ISCHIAL SPINES
- - 5 - above / +5 below
- The Cervix must DILATE & EFFACE - sign of true labor - cervix change
- Involuntary urge to PUSH & VOLUNTARY bearing down - increase RECTAL PRESSURE
- Effacement - thinning of the Cervix
- Dilation - opening of the softened cervix
- AVOID SUPINE -> Hypotension & Fetal Hypoxia - if Complain of Dizziness put on side
-
Vaginal Examination
- Cervical Dilation & Effacement - check Position of Baby
- Membranes - Intact or Ruptured - IF BAG OF WATER RUPTURED OR INTACT
-
Mechanism of Labor
- Engagement - Usually Biparietal (largest) diamenter of the Fetal Head ->ISCHIAL SPINES (referred to as station 0
- Descent, Flexion, Internal Rotation, Extension, Restitution & External Rotation, Expulsion --> CARDINAL MOVEMENTS OF LABOR
-
Uterine Contractions - during each contraction, the muscle fibers of the uterus tighten - THE ONSET OF TIGHTENING TO RELAXATION
- Assessment of Uterine Contractions
- Frequency, Duration & Intensity - INTERNAL
- Frequency & Duration - EXTERNAL
-
LABOR
- 4 Stages of Labor
- Stage 1 -
- Latent - 0-3 cm
- Active- 3-7 cm
- Transitional - 7-10 cm (shortest most difficult) - irritable withdrawn vomiting
- Stage 2 - Expulsion - Baby Born
- Stage 3 - Placental - Placenta Out
- Stage 4 - Recovery
- Latent Phase - Nx Considerations - Leopold's Maneuvers - POSITION & PRESENTATION
- Transition -
- Cervix @ 8-10 cm complete dilation
- Mother is Tired restless irritable - FEEL WITHDRAWN - RESISTANT TO TOUCH
- Shortest most difficult part of Labor - FOR TRANSITION
- Nx Consideration - OBSERVE for PERINEAL BULGING/CROWNING
- 2nd Stage of Labor
- URGE TO BEAR DOWN - BEARING DOWN REFLEX - begins with full dilation & ends with Birth ->10 cm- B
- 3rd Stage of Labor
- Begins with delivery of the Infant & ends with delivery of the Placenta
- Duration 5-30 minutes
- Schultze Presentation - shiny surfaces - BABY SIDE
- Duncan Presentation - dull surfaces - MOM SIDE
- Nx Consideration - Placental separtion --> CORD IS LENGTHENING --> UMBILICAL CORD APPEARS TO LENGTHEN AS PLACENTA DESCENDS
- 4th Stage of Labor
- Nx Considerations - Massaging the Uterine Fundus and/or BOGGY UTERUS TX: MASSAGE FUNDUS
- Encourage voiding to prevent bladder distention or DEVIATION TO THE SIDE - BLADDER UTERINE ATONY - SOFT BOGGY UTERUS
- LEOPOLD MANEUVER - Identify Presenting Part of Position of the BOdy
- Presenting part over lies the Pelvic Inlet
- NORMAL FETAL HEART TONE - 110 - 160
Fetal Scalp Electrode (FSE) an Internal Fetal Heart Monitor & Intrauterine Pressure Catheter (IUPC) an internal Contraction monitor --> MEMBRANES MUST BE RUPTURED
-
Pain Management During Labor & Delivery - Supine Position only with wedge under client's hips to tilt the uterus - PUT ON SIDE TO PREVENT MATERNAL HYPOTENSION & FETAL HYPOXIA
-
Epidural Block - May cause HYPOTENSION, FETAL BRADYCARDIA, INABILITY TO FEEL URGE TO VOID, ADMINISTER IV FLUIDS TO OFFSET HYPOTENSION (select all)
-
FHR Pattern & Contraction Monitoring
- Continous External Fetal Monitoring - DOES NOT MEASURE THE INTENSITY of Contraction
- Continous Internal Fetal Monitoring - Measures FREQUENCY DURATION & INTENSITY --> MEMBRANES MUST RUPTURE , CERVIX OPEN 2-3 CBM
- Indications for use of IExternal & Internal Fetal Monitoring -->PREVIOUS STILL BIRTH - is the indication for the needs of Electronic Fetal Monitor
- Fetal Assessment during Labor
- Decrease in Fetal Heart Rate are compression of - Fetal Head, Umbilical Cord, Uterine Myometrial Vessels
- BASELINE FETAL HEART RATE - 110-160 BPM
- Fetal Bradycardia may result from - FETAL HYPOXIA - TURN TO SIDE INCREASE O2
- Fetal Heart Rate Variability
- The Baseline rate should vary 10-15 beats over a period of 1 minute
- Short Term Variability (BEAT TO BEAT) --> SINGLE MOST RELIABLE INDICATOR OF FETAL WELL BEINGDecreased variability may occur in the ff situations - HYPOXIA & ACIDOSIS <7.2 ACIDOSISPeriodic/NonPeriodic HR changes --> Accelerations (IHR) Decelerations (DHR) Late & Prolonged
- Early Decelerations - PRODUCES MIRROR IMAGE - COINCIDES TO CONTRACTION
- Late Deceleration -
begins after the Onset of the peak or Middle of Contraction
- NX Criteria if an Ominous Pattern Occurs: STOP ANY OXYTOCIN/PITOSSIN, STOP LABOR, INCREASE IV FLUIDS
-
INTERPRETING FHR DATA
- Variability of 10-15 beats above or below FHR baseline is acceptable
- Early Decelerations (coincide) occur at the same time as the contraction
-
THERAPEUTIC PROCEDURES TO ASSIST WITH LABOR & DELIVERY
- AMNIOTOMY - artificial rupture of the Amniotic Membranes (AROM) -->
- ALWAYS CHECK INCREASE OF CORD PROLAPSE
- MONITOR FOR LATE DECEL & FETAL BRADYCARDIA
- RISK FOR PROLAPSE OF UMBILICAL CORD
-
THERAPEUTIC PROCEDURES TO ASSIST WITH LABOR & DELIVERY
- INDUCTION OF LABOR -
- Administration of IV Oxytocin/Pitocin - (MONITOR I/O CAUSES H20 INTOXICATION
- MEDICATIONS TO INDUCE LABOR
- Prostaglandins
- Intravenous Oxytocin/Pitocin -->
- Contractions - STRONGER, > PAINFUL, ABRUPT PEAK
- Monitor:
WATER INTOXICATION & HTN (CHECK I/O) May cause uterine Hyperstimulation & serious uterine tetany (TETANY -> FETAL HYPOXIA
- INDICATIONS for the Use of Episiotomy - SHOULDER DYSTOCIA - NOT A ROUTINE, NOT ALWAYS DONE & THEY ARE INVASIVE
- Indications & Risk Factors for C-BIRTH
- CPD - Cephalopelvic Disproportion
- ACTIVE GENITAL HERPES
-
PRETERM MEDICATIONS - GIVEN TO STOP LABOR
RITODRINE (Yutopar) TOCOLYTIC given IV - STOPS PRETERM LABOR & PREVENT SEIZURES
-
COMPLICATIONS OF LABOR & BIRTH
- Prolapsed Umbilical Cord
- Using Sterile Gloved hand insert 2 fingers into vagina & apply to the fetal presinting part to elevate it off the cord - GET PRESSURE OF CORD, TO RELIEF THE PRESSURE OF THE CORD
- Amniotic Fluid Embolism
- DIC is also associated with Internal Fetal Demise (Death) in Utero - THERAPEUTIC ABORTION
- Fetal Distress
- Activity Fetal Blood pH <7.2 - ACIDOSIS
