Brief Summary
- Full term pregnant female patients presented for elective C.S for single viable fetus will be included in this study.
- Before anesthesia, the patient will be attached to a monitor of: ECG , heart rate, non invasive blood pressure, pulse taximeter applied on the index finger of the limb not attached to the blood pressure cuff, pulse oximetry and plethysmographic variability index (PVI) and perfusion index (PI) will be taken by (Massimo radical 7, Massimo corp. USA). Measures will be recorded every 5 minutes preoperative.
- Patients with PVI \<15 will be excluded from the study.
- Patients with PVI \> 15 are started on intravenous infusion of warm ringer lactate solution via suitable pore intravenous cannula to reach target of PVI \<15 or a total 1 liter of ringer lactate.
- The patients in which the PVI is corrected by fluid to level below 15 will be Group (C) or corrected group. Patients in which intravenous fluid administration did not result any change in PVI or changed but still higher than 15 will be Group (NC) or non corrected group. After preoperative preparation patient is shifted to operating theater, with all monitors applied. She will receive spinal block at lumbar 3-4 space with hyperbaric bupivacaine 8 mg plus 25 mic fentanyl. After giving anesthesia and positioning for surgery with a left lateral tilt of 15 degrees,

Conditions
Outcome Measures
Primary Outcomes (1)
The incidence of post-spinal anesthesia hypotension
The decrease in the mean arterial pressure below 65 mmHg or below 80% of the baseline value.
Through out the whole intraoperative period
Secondary Outcomes (1)
The consumption of vasopressors
Through out the whole intraoperative period
Study Arms (2)
Corrected group
The patients in which the PVI will corrected by fluid to level below 15
Uncorrected group
Patients in which intravenous fluid administration didn't result any change in PVI or changed but still higher than 15
Interventions
The patients will receive spinal block at lumbar 3-4 space with hyperbaric bupivacaine 8 mg plus 25 mic fentanyl. After giving anesthesia and positioning for surgery with a left lateral tilt of 15 degrees, supplemental oxygen at rate of 4 liter/minute is applied.
