Supine Hypotensive Syndrome

supine hypotensive syndrome, cesarean delivery, spinal anesthesia, CSEA
Brief summary
Supine hypotensive syndrome often occurs following spinal anesthesia for cesarean delivery.In our study we base the regulation and drug administration both on the regular monitor and on a novel monitor which reflects upon the hemodynamic changes. Our aim is to observe whether the outcome of SHS patients with anesthesia management based on hemodynamic figures differs from those based on experience.
Interventions
PROCEDURELiDCOrapid
According to the illustration of the patient's hemodynamic figures shown on the LiDCOrapid monitor, we decide on the timing of the vasopressor administration. This group aims to maintain the cardiac output within a baseline range.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Umbilical arterial blood gas PH | 30minutes | The value is tested immediately after the blood sample is achieved after the infant is born. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Discomfort Score | 1day | we explored a scoring system to quantify the SHS symptom scale from 0 to 8, score high means more symptoms of SHS occurred |
| total vasopressor dosage | 30 minutes | total vasopressor given during the time span between the operation began to the baby was delivered |
| Umbilical blood gas lactate | 30minutes | The value is tested immediately after the blood sample is achieved after the infant is born. |
| Time span | 2 hours | the period between the operation began to the baby was delivered |
