Pulmonary artery perfusion with blood vs no perfusion during cardiopulmonary bypass

Mortality within the longest · adult surgical patients with the need for cardiopulmonary bypass‐dependent heart surgery

It is very uncertain whether pulmonary artery perfusion with blood changes all‐cause mortality within longest compared with no perfusion during cardiopulmonary bypass (very low certainty).

Pulmonary artery perfusion with blood vs no perfusion during cardiopulmonary bypass

Number of participants with pulmonary events within longest · adult surgical patients with the need for cardiopulmonary bypass‐dependent heart surgery

The review found no eligible studies for this question.

Pulmonary artery perfusion with blood vs no perfusion during cardiopulmonary bypass

Participants with ≥ 1SAE within longest · adult surgical patients with the need for cardiopulmonary bypass‐dependent heart surgery

It is very uncertain whether pulmonary artery perfusion with blood changes participants with ≥ 1SAE within longest compared with no perfusion during cardiopulmonary bypass (very low certainty).

Intervention not reported

HIT in people undergoing major surgical procedures · people undergoing surgical procedures and treated with UFH or LMWH for prophylaxis of thrombotic events lasting at least 5 days

The intervention may leads to lower HIT in people undergoing major surgical procedures (low certainty).

Intervention not reported

HIT complicated by venous thromboembolism · people undergoing surgical procedures and treated with UFH or LMWH for prophylaxis of thrombotic events lasting at least 5 days

The intervention may leads to lower HIT complicated by venous thromboembolism (low certainty).

Early discharge vs non‐early discharge

Treatment failure; rehospitalization or adjustment of antimicrobial treatment (or both) in number of episodes · children with cancer

Early discharge showed no clear difference in treatment failure; rehospitalization or adjustment of antimicrobial… compared with non‐early discharge (low certainty).
