Every Mom’s Dream…...
Care is a state in which something does matter ; it is the source of human tenderness
DEFINITION AN UNFORESEEN COMBINATION OF CIRCUMSTANCES OR THE RESULTING STATE THAT CALLS FOR IMMEDIATE ACTION LIFE -OR -DEATH SITUATION INFREQUENT, UNANTICIPATED, UNPREDICTABLE NIGHTMARE
Patient -1 A 38 weeks G4P3 lady presents with ROM and contractions. She is quite distressed and thinks the baby is coming out. You perform a pelvic examination and next to the head you feel a pulsatile cord…
Cord Prolapse Presentation: Cord in front of presenting part before the rupture of membranes Prolapse: Cord in front of presenting part after rupture of membranes
Occult prolapse Cord lying alongside the presenting part
Incidence (Anita pal, Kushgla, Sood 2006) Primigravida 0.45% Multigravida0.66% (Risk ratio 2:3) Cephalic0.3% Frank breech0.9% Complete breech5% Footling10% Shoulder15% Contracted pelvis4-6 times
Prevention Refer to level II care USG for malpresentation and cord presentation Foetal mointoring Avoid ARM in an unengaged head PV exam after ROM
Management Lift presenting part off the cord Instruct NOT to push Position patient Knee chest Trendelenburg Exaggerated position
Knee chest position
Exaggerated sim’s position
Management (cont..) Full bladder (Vago 1970) Vulval pad Replacement of cord Tocolysis (ritodrine) Forceps (Cx fully dilated) Second twin – internal podalic version and breech extraction Stat C-section Occult: Aminoinfusion
Management (cont…) Funic Reduction –Manual replacement of cord into uterus –Cord gently pushed above presenting part while other cord decompression techniques are applied –Rapid vaginal delivery
Fetal Mortality Overall - 50% 1 st stage of labour- 70% 2 nd stage of labour-30% Neonatal death- 4% Perinatal mortality- 20% 5 mins, damage and death.
VASA PRAEVIA Fetal blood vessel lies in front of presenting part Rupture - exsanguination of the fetus
Cause and Management Velamentous insertion Fresh bleeding vaginally with rupture of membranes Management: Signs of fetal distress Stat C.S Send cord blood for Hb estimation
PATIENT -2 Mother is pushing with each contraction and the baby’s head starts to come out. However, with each push, the baby’s head comes out and then retracts back in towards the perineum. You quickly recognize this as the “turtle sign”
Obstructed labour No advancement of presenting part despite strong, uterine contractions Causes: Cephalo-pelvic disproportion Malpresentation - shoulder/brow/persistent mento posterior Deep transverse arrest Pelvic mass Fetal abnormalities - Hydrocephalus, conjoined twins
Signs of obstructed labour Presenting part fails to advance Cervical dilatation slow Formation of retraction ring Early rupture of membranes Formation of elongated sac of forewaters If neglected, dehydration, ketosis Caput succedaneum and moulding urine output decreases fetal distress
Management Careful assessment of progress of labour Correct hydration Internal version Forceps application Stat C.Section
Shoulder Dystocia Incidence: 0.23% to 2.09% Impaction of fetal shoulders in maternal pelvis Head to body delivery time > 60s
Risk factors Maternal Diabetes Mellitus Short stature Macrosomia Post-term Obesity Fetal shoulder circumference 40.9 ± 1.5cm Vs 39.5 ± 1.5 cm
Complications Fetal morbidity: Brachial plexus injury Clavicular fracture Facial nerve paralysis Asphyxia CNS injury complication rate up to 20%
Management Help – obstetrician, pediatrician Episiotomy Legs – elevate (McRoberts) Pressure - suprapubic Enter vagina – Rubin’s and Woods’ screw Roll or Remove posterior arm Zavanelli, Clavicular#, Symphysiotomy
McRoberts Maneuver hyperflexion of maternal hips Increases intrauterine pressure (1,653mmHg - 3,262 mmHg) Increases amplitude of contractions (103mm Hg to 129mm Hg)
All-Fours Maneuver(Gaskin Maneuver) Ina May Gaskin (1976) changes pelvic dimensions in a similar way to McRoberts maneuver apply downward traction to disimpact the posterior shoulder
Suprapubic Pressure direct posterior or oblique suprapubic pressure
Rubin’s Maneuver adduction of the most accessible shoulder moves the fetus into an oblique position and decreases the bisacromial diameter
Woods’ Cork Screw Maneuver Abduct posterior shoulder exerting pressure on anterior surface of posterior shoulder
Deliver posterior arm (Barnum Maneuver) grasp the posterior arm and sweep it across the anterior chest to deliver
Zavanelli Maneuver cephalic replacement via reversal of the cardinal movements of labor
fracture the anterior clavicle by pushing it against the pubic ramus or using a closed pair of scissors Symphysiotomy Clavicular Fracture
Patient - 3 Mother in third stage of labour. Using the controlled cord traction, the midwife tries to deliver the placenta. Unfortunately, notices the descent of uterus instead of placenta.
Uterine Inversion 1/20,000 deliveries Causes: uterine atony (40%) Increase in intra abdominal pressure Fundal attachment of placenta (75%) Short cord Placenta accreta Excessive cord traction
Degrees of uterine inversion 1st - Dimpling of fundus, remains above internal os 2nd - fundus passes through the cervix, but lies inside vagina 3rd - (complete) Endometrium with or without placenta is outside the vulva
Management Uterine relaxant (terbutaline 0.25 mg IV followed by 2 g of MgSO 4 over 10 min) Treat hypovolumeia Without placenta: Repositioning
Management(cont…) With placenta: Do not remove placenta Replace uterus Bimanual compression Hydrostatic pressure (O’Sullivan 1945) Start oxytocin Laparotomy
Patient - 4 A mother in second stage of labour suddenly complains of persistent pain, and bleeding per vagina becomes profuse and the monitor shows decelerations in fetal heart rate.
Uterine Rupture 1/2000 deliveries Types: Complete Incomplete Rupture Vs Dehiscense of C.S scar
Rupture of lower uterine segment
Causes Uterine injury sustained before current pregnancy C.S /hysterotomy/ repaired uterine rupture/ Myomectomy Uterine trauma - curette, sounds Sharp or blunt trauma - accidents, bullets, knives Congenital anomaly
Causes Uterine injury during current pregnancy Before delivery Intense spontaneous contractions Labour stimulation Intra-amnionic instillation Perforation by internal catheter External trauma - sharp or blunt External version Uterine overdistension - multiple pregnancy
Causes (cont…) During delivery: Internal version Difficult forceps delivery Breech extraction Difficult manual removal of placenta Fetal anomaly Acquired: Placenta increta / percreta Retroverted uterus (sacculation)
Diagnosis Prolonged fetal decelerations (70.3%) Bleeding (3.4%) Pain (7.6%) Monitor tracing demonstrating fetal heart rate decelerations, increase in uterine tone, and continuation of uterine contractions in a patient with uterine rupture monitored with an intrauterine pressure catheter.
Management Total Hysterectomy Sub total hysterectomy Simple repair
Patient 5 Mother has just delivered a male baby. You wait for 30 minutes But no signs of placental separation and descent is present. Manual removal fails.
Placenta Accreta Incidence: 1 in 2,562 deliveries Firm adherence of placenta to uterine wall partial or total absence of decidua basalis Placenta increta: Villi invade the myometrium Placenta percreta: Villi penetrate myometrium
Diagnosis and Management Dx in third stage of labour Maternal hemorrhage Treatment: Hysterectomy
Patient 6 A pregnant mother on oxytocin induction suddenly becomes short of breath and tachypneic. Vital signs drop and the patient goes into asystolic arrest.
Amniotic Fluid Embolism Incidence: 1 in 3,500 to 1 in 80,000 Amniotic fluid enters the maternal circulation and reaches pulmonary capillaries Through a tear in amnion and chorion Opening in maternal circulation Increased intrauterine pressure
Amniotic Fluid Embolism
Risk factors Multiparity Large fetus Meconium in amniotic fluid Intrauterine fetal death Precipitate labour Placental abruption Intrauterine catheter Rupture of uterus
Be prepared, except the unexpected and above all, communicate Communicate congruently Careful, sympathetic and optimal communication Avoid medical jargon Psychological support- one member - Touch “Talking through” the process Smile of reassurance Information and support to partners
Fear during labour Worries that infant may die or born with abnormality. Review labour process Provide with frequent progress report Personal availability of nurse Promise postnatal debriefing sessions
