ACOG Criteria for \_\_\_\_\_\_\_\_\_\_: 1 or 2 previous low-transverse C/S Clinically adequate pelvis No other uterine scars No Hx of uterine rupture Physician immediately available throughout active labor Physician capable of monitoring labor Physician able to perform 911 C/S Anesthesia/personnel available for 911 C/S
TOLAC
ACOG Criteria against attempting \_\_\_\_\_\_\_\_\_\_\_: Prior classical or T-shaped C/S incision Other transfundal surgery Contracted pelvis Medical/Obstetric complication Inability to perform 911 C/S
TOLAC
Risks to Consider but do not Preclude __________:
Multiple previous c/s
Macrosomia
> 40 week gestation
Unknown type of prior uterine incision - unless highly suspicious of previous classical incision, may still be candidates
Twin gestation - may be considered w/otherwise appropriate candidates
Obesity - high BMI alone is not an absolute contraindication
TOLAC
Signs of \_\_\_\_\_\_\_\_\_\_\_: Loss of station Fetal stress - *Bradycardia* Palpable parts in the abdomen Continuous abdominal pain - tends to refer to scapular/ shoulder area Increased vaginal bleeding Hypertonic or fewer contractions Lower amplitude Prolonged, late, or variable decels (Contraction pattern unreliable and often normal) (Can mirror s/s of abruption) Often remarkably little appreciable pain or tenderness
Uterine Rupture
Causes of \_\_\_\_\_\_\_\_\_\_\_\_\_\_: Before delivery: Persistent, intense, spontaneous contraction IOL w/ oxytocin or prostaglandins Intraamniotic installation w/ saline or prostaglandins Perforation by IUPC External trauma External version Uterine overdistention due to hydramnios Multifetal pregnancy During delivery: Internal version of second twin Difficult forceps delivery Breech extraction Fetal anomaly distending lower segment Vigorous uterine pressure during delivery Difficult manual removal of placenta Acquired: Placenta accrete syndromes Gestational trophoblastic neoplasia Adenomyosis Sacculation of entrapped retroverted uterus
