Stroke Volume Variations and Pulse Pressure Variations Undergoing Artificial Pneumothorax Surgery
Conditions: Artificial; Complications, Heart
Sex: All
Ages: 18 Years – 65 Years
Healthy volunteers: 1
Phase: NA
Enrollment: 6
Sponsor: Chinese PLA General Hospital
Location: China
Summary
Stroke volume variation (SVV) and pulse pressure variation (PPV) have been thought to be sensitive predictors of fluid responsiveness in mechanically ventilated participants.
In this paper, the investigators reported a special group of people to use SVV and PPV during their operation.
The maintenance of hemodynamic stability and the critical organ perfusion is crucial to the treatment for patients with artificial Pneumothorax during esophageal surgery, because artificial pneumothorax causes incomplete ventilation of one lung.
In addition, artificial pneumothorax may seriously affect theparticipant's heart and lung function, brings more challenges to the intraoperative anesthetic management, expecially in volume management.
Little information is available about the accuracy of SVV and PPV to predict fluid responsiveness in participants with artificial Pneumothorax during esophageal surgery.
It is unclear whether it will affect the accuracy of SVV and PPV, and whether it will cause the change of their threshold values.
The investigators will discuss it in the passage and the investigators will give an preliminary mechanism to explain the results.
