Conditions

Cerebral Oxygen Saturation During Spinal Anesthesia for Cesarean Delivery

Keywords

cerebral oximetry, cesarean delivery

Brief summary

The cerebral oxygen saturation is assessed by means of near-infrared spectometry in parturients undergoing cesarean delivery under spinal anesthesia. The investigators hypothesis was that spinal anesthesia does not influence cerebral oxygen saturation.

Design outcomes

Primary

Measure	Time frame	Description
cerebral oxygen saturation of the right frontal lobe	Change from the performing of spinal anesthesia untill 1 minute after delivery	Cerebral oxygen saturation is important as it may affect patient's outcome

Secondary

Measure	Time frame	Description
cerebral oxygen saturation of the left frontal lobe	5, 10, 50 min after spinal,1 minute after delivery	Cerebral oxygen saturation is important for patient's outcome
Thigh oxygen saturation	5, 10, 50 min after spinal, 1 minute after delivery	Thigh oxygen saturation may reflect blood redistribution due to spinal block
Arterial Oxygenation	5, 10, 50 min after spinal, 1 minute after delivery	Changes in arterial oxygenation may reflect blood redistribution due to spinal block

Other

Measure	Time frame	Description
Hemodynamic changes (Changes in Blood Pressure (mmHg) and Heart rate (beats/min)	5, 10, 50 min after spinal, 1 minute after delivery	Hemodynamic changes (changes in Blood Pressure and Heart rate) may reflect blood redistribution due to spinal block
