Clinical Trial: Venous Air Embolism in Cesarean Delivery, Especially Placental Previa

Study Status: Completed
Recruit Status: Completed
Study Type: Observational

Official Title:

Brief Summary: Effects of placenta previa on incidence and severity of venous air embolism in patients during cesarean delivery

Detailed Summary:
Sponsor: Yonsei University

Current Primary Outcome: 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).


Original Primary Outcome: read sonography recorded during the surgery [ Time Frame: after reading sonography ]
