Cerebral and Renal Oxymetry and Anesthetic Techniques in Newborns

Comparison of the Effects of Anesthetic Techniques Used for Cesarean Delivery on Neonatal Cerebral and Renal Oxygenation

Neonatal adaptation to extrauterine life has many physiological changes in neonatal organ systems. These adaptative changes may be affected such as type of delivery and anesthesia management at birth. near infrared spectroscopy (NIRS) is a popular non-invasive method that can be used in newborns thus monitorize tissue oxygenation regularly. In this study we have purposed to compare the effects of general anesthesia versus spinal anesthesia on newborn's cerebral and renal oxygenation in elective cesarean operations

The cases divided into two groups those spinal anesthesia group ( group:1; n:30 ) and general anesthesia group (group:2; n:30). The preoperative and intraoperative mean arterial pressures (MAP), heart rate (HR), arterial oxyhemoglobin saturation (SpO2), intraoperative blood loss values of pregnants and 1st-5th minute APGAR scores, preductal and postductal SpO2, perfusion index, heart rates, body temperature, cerebral and renal regional oxygen saturations of newborns after birth have been recorded.
