In which of these disorders is cardiopulmonary bypass required during lung transplantation?
Select Your Answer:
Patients with pulmonary hypertension are unable to tolerate clamping of the pulmonary artery and may show signs of right ventricular failure.
Also, if there is any evidence of pulmonary edema, cardiopulmonary bypass should be initiated.
However, the one major problem with the use of cardiopulmonary bypass is the potential for bleeding. Thus, after the anastomosis of the lung have been completed, it is mandatory to check the site several times before closure. Complete hemostasis is mandatory.
There are many advantages to using cardiopulmonary bypass during lung transplantation. The field of surgery can be clean and bloodless, and one can perform a precise anastomosis. Some surgeons elect to use partial cardiopulmonary bypass just to decompress the right ventricle.
