The relationships between uterine incision to delivery interval (U-DI) and neonatal umbilical blood acid-base status and Apgar scores at 1-minute were studied in 130 healthy parturients undergoing elective cesarean section under epidural anesthesia. U-DI was correlated with umbilical venous (UV) and umbilical arterial (UA) pH, PCO2 and PO2, and was also correlated with 1-minute Apgar scores. U-DI of more than 150 sec was associated with significantly higher UVPCO2, UAPCO2, lower UVpH, UApH, UVPO2, and UAPO2. The only two newborns with low 1-minute Apgar scores (6 and 3) in the present study both had prolonged U-DI (> 150 sec) and inhaled amniotic fluid just before the delivery. It is concluded that U-DI of more than 150 sec has considerable influence on the neonatal status.

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
