The pharmacokinetics of oxytocin as they apply to labor induction

Article Abstract:

Plasma levels of oxytocin may not correlate directly to uterine activity in pregnant women receiving oxytocin induction of labor. Rather, oxytocin levels in plasma may simply indicate the rate of oxytocin intravenous infusion. Researchers sampled blood before and during oxytocin infusion in 10 women undergoing labor induction. Oxytocin concentrations did not correlate with uterine pressure or uterine activity. Oxytocin levels did correspond to the rate of oxytocin infusion. Oxytocin concentrations as found in blood samples should not be used to figure oxytocin infusion rates or dosages. Instead, oxytocin dosing should be considered on an individual basis, accounting for gestational age, number of pregnancies, and cervical dilation.

Operative vaginal delivery - year 2000

Article Abstract:

The classification system developed by the American College of Obstetrics and Gynecology (ACOG) appears to reliably predict the risk to mother and baby during a forceps delivery. This system may also be appropriate for evaluating risk during vacuum extractor deliveries. Researchers highlighted the results of recent studies using the ACOG system. Forceps deliveries done when the baby has not progressed through the birth canal or when the baby is turned more than 45 degrees pose the greatest risk for complications to mother and baby.

The role of forceps rotation in maternal and neonatal injury

Article Abstract:

Rotating a baby 90 degrees or more during childbirth does not appear to increase the risk of injury compared to lesser rotations. A 90 degree rotation is one-fourth of a complete rotation, such as a clock that moves from 12 to 3. Researchers compared neonatal outcome in 113 babies who had been rotated 90 degrees or more and 167 who had been rotated 45 degrees or less. The rate of injury such as skull fracture, subdural hematoma, or cranial nerve injury was about 10% in both groups.
