Normal Delivery
For LU7
Objectives
To outline the conduct of normal labor and delivery
To define personnel requirements
Ideal Situation
How big should OBAS be?
Accurate Diagnosis of Labor
Contractions occur at regular intervals Intervals shorten Intensity increases Discomfort in back and abdomen Cervix dilates Discomfort not stopped by sedation
Transfer of patients
“A woman in true labor is considered unstable for interhospital transfer purposes until the child and placenta are delivered … unless the risks of transfer are outweighed by benefits of treatment at another facility…violation (carries) civil penalties of up to $50,000…” (Williams, 2001)
Electronic Admissions Testing
Non stress test is performed before patient is discharged from admitting of labor unit..
Vaginal examination Not performed if bleeding in excess of
bloody show Amniotic fluid egress examined using
sterile speculum to check for pooling Cervix softness, effacement,
dilatation, position Presenting part Station Pelvimetry
Monitoring in 1st stage
Fetal heart rate every 15 to 30 min (110-170 beats per minute)
Uterine contractions by intervals, duration and intensity
Maternal vital signs at least every 4 hours (hourly for hypertensives)
Vaginal examinations every 2 to 3 hours (hourly if in active phase)
Monitoring during 2nd stage
Fetal heart rate every 15 min for low risk and every 5 min for high risk
Positioning in lithotomy and prepping
Episiotomy Not routine Increases the risk
of tears through the rectum
Done once fetal head bulges through the perineum
Delivery of head Crowning is when
the largest diameter of the fetal head is encircled by the peritoneum
Ritgen’s maneuver Forward pressure
on chin of fetus in direct occiput anterior position once perineum is distended 5 cm or more
Favors extension of head
Delivery of shoulders Head in transverse
position and bisacromial diameter in AP
Sides of head are grasped and gentle traction exerted downward to deliver anterior shoulder from under symphysis pubis
Handling the nuchal cord
Delivery of placenta 4 signs of
separation Globular uterus Gush of blood Uterus rises Lenghtening of cord
Active management of 3rd stage
Oxtyocin drip 5 to 10 units after cord clamping
Methyl ergometrine 0.5 mg IM after placenta is delivered (deferred for hypertensive patients)
Management of 4th stage of labor
Involution of uterus Postpartum hemorrhage >500 cc
assessed (laceration, atony, etc.) Uterine massage and uterotonics
given (including misoprostol)
Repair of episiotomy
Features median vs. mediolateral episiotomy
Assess extent of tears Cervical lacertaion Urethral, periurethral Vaginal side walls Sphincter tears Rectal mucosal tears
Episorraphy Goal is to control
hemorrhage and restore anatomy without excessive suturing
Sutures used are chromic 2-O and vicryl 2-O with big round needle
