Intrauterine Resuscitation MeasuresLateral Positioning

• Optimize perfusion to uteroplacental unit

IV Fluid Bolus: Based on clinical condition

• Correction of maternal hypotension is essential!!

Oxygen Supplementation :• May optimize maternal oxygenation status and fetal oxygen delivery.

Defined: SBP >160mmHg, or DBP > 100mmHg, acute-onset, & persistent (>15 min)

Severe systolic hypertension--most important predictor of cerebral hemorrhage in OB patients• Goal B/P: Range of 140-160/90-100 mmHg to preserve fetal perfusion!!• Severe hypertension can occur antepartum, intrapartum or post-partum

Delivery Outside Of OB Unit : Now What??• Supplies: OB Kit & Neo Ventilation Device• Place infant on mothers abdomen after birth

• Clamp cord 8-10 inches from baby• Use 2 clamps several inches apart: cut between clamps• Delayed Cord Clamping X 30-60 seconds IF VIGOROUS• Immediate Cord Clamping IF NONVIGOROUS

• Provide basic newborn care• Clear Airway & Optimal Airway Positioning• Dry Thoroughly & Provide Warmth• Continuous assessment of ABC’s• Thermoregulation & Blood Glucose

IF NONVIGOROUS immediate umbilical cord clamping & NRPThermoregulation & Neuroprotection:

Warming mattress, isolation bag, hat, nesting, & head alignment with gentle handling

NRP Guidelines:

Sp02 & ECG, CPAP, PPV, airway & perfusion support, careful fluid administration, glycemic control, early activation of neonatal & transport teams!
