A dose of a short-acting tocolytic (terbutaline 0.25 mg sc) may help some women. The success rate is about 50 to 75%. The success rate is about 50 to 75%. How to do External Cephalic Version Cases of intrapartal fetal distress from any cause sustain further hypoxia during uterine contractions due to the concomitant reduction in uterine blood flow during uterine activity. Intrauterine resuscitation consists of applying specific measures with the aim of increasing oxygen delivery to the placenta and umbilical blood flow, in order to reverse hypoxia and acidosis. Intrauterine resuscitation may be used as part of the obstetric management of labour, while preparing for caesarean delivery for fetal distress, or at the time of establishment of regional analgesia during labour in the compromised fetus. The principles may also be applied during inter-hospital transfers of sick or labouring parturients. A randomized study on the effect of terbutaline on fetal distress was carried out in 20 patients who showed evidence of ominous fetal heart rate patterns and fetal scalp blood pH values of 7.25. Intrapartum Intra-uterine resuscitation (IUR) Episodes of intrapartum CTG abnormalities, including prolonged bradycardia, may be associated with fetal hypoxia, which if prolonged may lead to neurological sequelae. •Terbutaline •O2 by face mask •Delivery. Intrauterine Fetal Resuscitation •Ascertain and direct interventions based upon underlying pathophysiology •Maximize maternal cardiac output •Increase oxygen content in the blood •Relieve umbilical cord compression. Fetal Oxygenation CO2 O2 CO2 O2 CO2 O2 • Fetal pO2 much lower • Fetal pCO2 much higher • Blood flow regulates pO2 and. Terbutaline, a selective beta-2 adrenergic receptor stimulator, has been used to decrease myometrial activity and improve uteroplacental blood flow in 15 patients with acute intrapartum fetal distress. In all cases electronic monitoring gave evidence of partial or total fetal recovery after therapy terbutaline 0.25 mg subcutaneous (0.5 ml from a 1ml ampoule). alternatively for immediate action GTN sublingual spray, 2 puffs initially, repeat after 1 minute until contractions stop, maximum 3 doses •. Terbutaline, a selective beta-2 adrenergic receptor stimulator, has been used to decrease myometrial activity and improve uteroplacental blood flow in 15 patients with acute intrapartum fetal distress.
