Venous Air Embolism in Cesarean Delivery, Especially Placental Previa
Overview
Effects of placenta previa on incidence and severity of venous air embolism in patients during cesarean delivery
Study Type
- Study Type: Observational
- Study Design
- Time Perspective: Prospective
- Study Primary Completion Date: September 2009
Interventions
- Procedure: cesarean delivery
Arms, Groups and Cohorts
- placental previa
Clinical Trial Outcome Measures
Primary Measures
- read sonography records during the surgery
- Time Frame: After 1 or 2 weeks of surgery
- Three sono views will be recorded rapidly for later interpretation of the stage of air embolism. The midesophageal (ME) 4-chamber view will be continuously monitored during surgery and videotaped. When a bubble is detected in the right atrium (RA), the probe will be turned to the right side and the angle was adjusted to the ME bicaval view to confirm its entrance from the inferior vena cava. Then, the angle will be rapidly re-adjusted to view the ME right ventricle (RV) inflow-outflow view to confirm the extent of air embolism through the right ventricular outflow tract (RVOT).
