Abstract

Introduction: The use of Vacuum-assisted Venous Drainage (VAVD) in cardiopulmonary bypass is a standard in many perfusion practices. This scoping review targets the need for all positive and negative effects to be accounted for when using VAVD. A well thought out scoping review is the basis for additional research like a systematic review to be assembled. The goal of this scoping review is to encompass this topic to the best of its ability and supply relevant data in this field.

Methods: This scoping review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The databases were searched from January 1, 2000, to January 1, 2025. Seventeen articles and one grey literature article were derived and labeled as observational studies directly related to the use of VAVD on cardiopulmonary bypass.

Results: All relevant literature presented in this scoping review either highlights a positive or negative effect of VAVD and its use in cardiopulmonary bypass. Two articles found a difference in the overall flow to the patient. Three articles found no evidence in hemodilution being a factor with VAVD. Although, two articles found evidence of hemodilution when certain levels of negative pressure were reached while using VAVD. Three articles found no evidence suggesting that VAVD creates more micro air embolism. Two articles found evidence suggesting less need for blood products while using VAVD.

Conclusion: This scoping review highlights the need for additional studies that encompass the possibility of all positive and negative effects that come with the use of VAVD on cardiopulmonary bypass.
