Breech
Malposition of the Occiput
When the fetal occiput lies adjacent to the sacroiliac joint and occupies either the left or right posterior quadrants of the mother's pelvis with the brow directed anteriorly
Causes of malposition of the Occiput
Modern lifestyle and poor posture
Decrease nutrition and lifestyle of the mother affects the fetus
Useofepidural anesthesia
Decrease the tone of the pelvic floor muscle which results in failure of the vertex to rotate = OPP
Android Pelvis
Heart shaped pelvis same with the male pelvis which has a narrow floor pelvis which forces the fetus to take OPP
Assessment of malposition
On inspection: abdomen appears flattened, or slightly depressed, below the umbilicus
On palpation: fetal head is high, the occiput and brow may be felt at the same level at the pelvic inlet, while the fetal back can be palpated out in the flank
On Auscultation: The fetal heart sounds can be heard in the midline just below the umbilicus
Complications of OPP
Early rupture of the membranes
Cord prolapses
Prolonged labor
Premature expulsive effort
Infection
Maternal exhaustion
Interventions for OPP
Communication and support
One-to-one care
General comfort and pain relief
Ambulation and position
Assessment of progress
Effective assessment of maternal and fetal wellbeing
Appropriate and decisive clinical decisions
Appropriate referral when necessary
Accurate and detailed record-keeping
Malpresentations of the Fetus
Refers to the orientation of the fetus and may be diagnosed during pregnancy or in labour. Any presentation other than vertex is termed a malpresentation.
Types of Malpresentations
Breech
Face
Brow
Shoulder
Breech presentation
Fetal buttocks lie lowermost in the maternal uterus and the fetal head occupies the fundus. Longitudinal lie, common before 37th weeks.
Types of Breech presentation
Flexed or complete breech - the fetus sits with the thighs and knees flexed with the feet close to the buttocks
Extended or frank breech - the fetal thighs are flexed, the legs are extended at the knees and lie alongside the trunk, with the feet near the fetal head
Footling presentation - one or both feet present below the fetal buttocks, with hips and knees extended
Causes of Breech presentation
Primigravida
Uterine anomalies
Oligohydramnios
Placental location
Uterine fibroids
Contracted pelvis
Fetal anomalies
Hydrocephalus
Multiple pregnancy
Maternal alcohol or drug abuse
Grand multiparty
Polyhydramnios
Prematurity
Face presentation
Occurs when the head and neck are hyperextended but the limbs flexed, so that the fetus lies in the uterus in a curious S-shaped attitude with the occiput against its shoulder blades and the face directly presenting
Nursing Assessment of Face presentation
The back of the fetus is difficult to outline, and a deep furrow can be palpated between the hard occiput and the fetal back
Fetal heart tones can be heard on the side where the fetal feet are palpated
Brow presentation
The head is midway between flexion and extension
Shoulder presentation
Shoulder presentation occurs as a result of a transverse or an oblique lie
Nursing Assessment of Shoulder presentation
Identify a transverse lie by: inspection and palpation of the abdomen, auscultation of FHTs in the midline of the abdomen, vaginal examination
On palpation, no fetal part is felt in the fundal portion of the uterus or above the symphysis pubis
The head may be palpated on one side and the breech on the other
FHTs are usually auscultated just below the midline of the umbilicus
On vaginal examination, if a presenting part is palpated, it is the ridged thorax or possibly an arm that is compressed against the chest
Women with a transverse lie may report less shortness of breath, pelvic pressure, and urinary frequency than other women because pressure is not exerted on the diaphragm and the bladder
Forceps delivery
Forceps are designed to assist the birth of a fetus by providing traction or by providing the means to rotate the fetal head to an occiput-anterior position
Indicators/Risk Factors for Forceps delivery
Fetal Factors: Second stage of labor fetal distress, Abnormal presentation, Preterm labor to protect fetal head from injuries
Maternal Factors: To shorten the second stage of labor, Ineffective expulsive effort/poor progress, Exhaustion medical disease like cardiac disease
Prepare client and family, Provide psychological support to allay/decrease anxiety, Monitor FHT continuously, Assess mother and infant for complications
Contraindications to Vacuum Extraction
CPD, Nonvertex presentations, Maternal or suspected fetal coagulation defects, known or suspected hydrocephalus, Fetal scalp trauma, Fetal macrosomia, High fetal station, Face or breech presentation, Gestation less than 34 weeks, Incompletely dilated cervix
