Change of cardiac output (L/min) after spinal block

研究概览

简要总结

Spinal block leads to the reduction of systemic vascular resistance (SVR) which may effect the cardiac output. Ngan Kee et al. has showed that spina block with 0.5% hyperbaric bupivacaine for Cesarean section combined with intravenous infusion norepinephrine had higher cardiac output than those who received phenylephrine

研究组 & 干预措施

Isobaric Marcaine

Experimental

Isobaric Marcaine 2.2 mL for spinal block

Change of cardiac output (L/min) after spinal block

时间窗: 5 minutes after spinal block

The investigators will measure cardiac output using non-invasive methods (USCOM) before spinal block and 5 minutes after spinal block.

次要结局

  • Total dose of vasopressor(2 hours)
  • Number of patients who experience systolic blood pressure < 25% of preoperative measurement(2 hours)
