Spectral parameters may be used to establish significant differences between normal and pathological fetal outcomes based on pH and base deficit
The infant factors that were associated with poor outcome (severe HIE or death) were low Apgar scores at 5 and 10 minutes, need for adrenaline, delay in time to spontaneous respiration, low pH, high base deficit
and low bicarbonate.
Recovery Room--Postoperative Monitoring Level IIB Level III Swann-Ganz - - Central Venous Pressure +/- + Echocardiography - + Vital Signs/EKG + + Urine Output + + Chest X-ray - + Bronchoscopy - + POSTOP LABS: Base Deficit

The values termed "base excess" or "base deficit
" are used to quantify the magnitude of metabolic acidosis during normal stages of labor.
There was a trend towards a significant difference between the groups of survivors and non-survivors when the base deficit
of greater or less than -4 was evaluated (p = 0.057).
The relationship of base deficit
to lactate in porcine hemorrhagic shock and resuscitation.
Arterial blood gas measurement revealed a profound metabolic acidosis, with a pH of 7.06, a serum bicarbonate level of 14.2 mmol/l and a base deficit
of -15.0 mmol/l.
Fetal umbilical cord arterial blood obtained at delivery with evidence of metabolic acidosis (pH less than 7 and base deficit
of 12 mmol/L or more).
