Energy expenditure in normal labor.
The energy expenditure in 23 healthy parturient women during spontaneous labor was assessed by continuous measurement of their O2 consumption and CO2 production. Due to the intermittent character of uterine contractions, normal labor and delivery did not impose high energy demands on the parturient, whereas a prolonged labor and delivery in which energy input was high led to maternal metabolic disturbances.
