1. 1 Obstetrical Pearls Acer_user
2. 2 OB Emergencies Postpartum Hemorrhage
Ecclampsia
Non Reassuring FHR/ Distress
Shoulder Dystocia
Uterine inversion
Placental Abruption
Breech
Ruptured uterus
3. 3 Postpartum Hemorrhage Causes- Retained placenta, lacerations, Atony, Infection
Identify the cause if able
Empty clots and placenta from uterus
Start second line large bore IV
If lacerations repair them( may need general anesthesia in some)
4. 4 Management of PP hemorrhage Pitocin 10-40 units per liter of IV fluid (antidiuretic effect, Hypotension if given IV push, it can be given IM)
Methergine 0.2mg IM (not to be given IV can cause severe hypertension)
Prostaglandin E2 supp 20mg rectally
5. 5 Management of PP Hemorrhage Prostaglandin F2 alpha 250 micrograms IM (Hemabate)
Cytotec 200-400 micrograms
D&C
Uterine packing
Hypogastric artery ligation
Hysterectomy
Replace clotting factors with FFP 1 units for every 4 of PRBC
6. 6 Ecclampsia The occurrence of convulsions in a patient that meets the criteria for preeclampsia and no other neurologic reason for seizure
HTN, Proteinuria, edema
Incidence 1/700-1/1000 pregnancies
1/3 of seizures occur PP
7. 7 Ecclampsia Treatment Best treatment is prophylaxis with MgSO4
MgSO4 bolus 4-6grams run at 1-3grams/hr
If still seizing after initial bolus rebolus with 4 grams
If no IV access MgSO4 10grams IM
8. 8 Ecclampsia Treatment If already on MgSO4 check level and bolus
Sodium Amobarbital 250mg IV slowly (may need to intubate)
Last resort Diazapam 5-10mg slow IV or Phenytoin but needs to be on cardiac monitor
Both can severely sedate mom and baby
9. 9 Non Reassuring FHR/ Fetal distress Over diagnosed
Normal fetal heart rate with an episode of bradycardia usually can undergo intrauterine resuscitation ( make sure no tetanic contractions)
Poor tracing with episode of bradycardia is much more serious
10. 10 Non Reassuring FHR Persistent late decelerations
Loss of variability
Tachycardia
Deep or Severe variable decelerations
No response the fetal scalp stimulation
11. 11 Intrauterine resuscitation IV fluid bolus
Reposition the patient
If hypotensive give ephedrine
Stop Oxytocin
+/- Brethine SQ
Check cervix
O2 with rebreather mask
Fetal scalp electrode
12. 12 Non Reassuring FHR If close to delivery attempt vaginal delivery (faster)
If remote from delivery prepare for Cesarean Section-
13. 13 Shoulder Dystocia Unpredictable event
1%-4% of pregnancies
Risk factors- DM, Macrosomia (poor predictors)
Less than 10% of shoulder dystocias result in permanent brachial plexus injury
14. 14 Management of Shoulder Dystocia No Fundal pressure
McRoberts Maneuver- Flex mothers legs up to abdomen
Suprapubic pressure
Woods Corkscrew Maneuver
Delivery of Posterior shoulder
Zavenelli Maneuver
Always get help!
15. 15 Uterine Inversion Usually iatrogenic occasionally spontaneous
Contributing factors are accretas, excessive traction on the cord
Hypotensive shock out of proportion to blood loss
May be partial or complete inversion
16. 16 Treatment of Uterine inversion Get help
Anesthesiology
If able reinvert the uterus with a hand
Usually leave placenta attached
2 Large bore IV lines with LR, blood if needed
Halothane or MgSO4
17. 17 Treatment of uterine inversion Once reinverted start oxytocin, methergine, prostaglandins, and stop any uterine relaxants
Rare cases laparotomy with combined vaginal replacement
18. 18 Placental abruption Associated incidents- Trauma, HTN, Preeclampsia, eclampsia, cocaine, cigarettes (Recurrence rate 1/18)
Frequency1/85 deliveries
Consumptive coagulopathy can result
PT, PTT, Fibrinogen, FSP, CBC and platelets
19. 19 Management of Placental Abruptions 2 large bore IV
Blood products
Usually Cesarean Section
These can be concealed so have a high index of suspicion
Ultrasound- need a 30% abruption to be seen
Avoid vasodilators
20. 20 Breech Only a true emergency if delivery is immanent
Best if frank or complete breech
Do not apply traction to the body just support the body and allow mother to push
If able keep the head flexed
Suprapubic pressure on occasion
21. 21 Ruptured Uterus Associated conditions- previous uterine surgery, trauma, grand multiparas, Uterine anomolies (very rare in primagravidas)
Signs –abdominal pain,tenderness, shock, vaginal bleeding, Cessation of labor, fetal death
Most case do not occur in labor
22. 22 Ruptured uterus Do not attempt vaginal delivery
Immediate surgery
C/S, hysterotomy, hysterectomy
Type and cross for 6 u PRBC
Rupture may take place with a vaginal delivery
23. 23 Why give antenatal steroids? Decrease incidence or respiratory distress syndrome
Decreased incidence or intraventricular hemorrhage
Decreased neonatal mortality
Decreased neonatal morbidity
24. 24 Who gets Steroids? Patients with preterm labor that threaten to deliver
At least 24 weeks (for PTL) up to 34 weeks
Preterm rupture of membranes 24-32 weeks
Betamethasone 12mg IM q 24 (2 doses)
Dexamethasone 6mg q 12 X 4
25. 25 Down side of antenatal steroid use If chorioamnionitis is present can worsen maternal and fetal conditions
#1 side effect is pulmonary edema (especially if used with tocolytics)
Increases contractions
Elevates blood sugars
Multiple doses have unknown long term effects (1 rescue dose)
26. 26 Preterm Labor Causes Unknown
Infection
Uterine anomolies
Over distension (multiple births, macrosomia, polyhydramnios)
Trauma
Abruption
27. 27 Causes of Preterm Labor Anemia
Hypoxia to the uterus
28. 28 Evaluation of patients with preterm labor History and Physical
Vaginal cultures GC, Chlamydia, BV
Fetal Fibronectin if negative 95% chance of not delivering in the next 14 days. If positive the correlation to delivery is poor
Cervical length less than 2.5cm
29. 29 Evaluation of Patients with preterm labor Limited digital pelvic exams
Tocodynomometer
CBC, UA +/- culture, U/S
30. 30 Treatment for preterm labor No scientific proof anything works
Hydration and bed rest
Treat infections
MgSO4 (4-6gm bolus+ 1-4gm/hr)
Terbutaline 0.25 SQ, 2.5-5mg po
Ritodrine
Indocin (less than 32 weeks)
Nifedipine
31. 31 Review Get help
Any patient can turn into a catastrophe
Try not to panic
Nurses have been through it before
32. 32 L&D orientation If you want to do D&C’s watch the OR schedule
If you are the resident on a case that goes to C/S you are expected to scrub
7:30 morning lecture M-F
Don’t be late
33. 33 Orientation to L&D If you aren’t sure ask!
Be persistent when asking for help
Nurse can be part of your education
Don’t worry about bothering an attending
Don’t be hard to find
Help out
Don’t pass the tough stuff off to the OB/GYN residents
Never lie
