摘要
Donor management is the key in the complex donation process,since up to 20%of organs of brain death donors(DBD)are lost due to hemodynamic instability.This challenge is made more difficult due to the lack of strong recommendations on therapies for hemodynamic management in DBDs and more importantly to the epidemiologic changes in these donors who are becoming older and with more comorbidities(marginal donors).In the present manuscript we aimed at summarizing the available evidence on therapeutic strategies for hemodynamic management(focusing on vasoactive drugs)and monitoring(therapeutic goals).Evidence on management in elderly DBDs is also summarized.Donor management continues critical care but with different and specific therapeutic goals since the number of donor goals met is related to the number of organs retrieved and transplanted.Careful monitoring of selected parameters(possibly including serial echocardiography)is the clinical tool able to guarantee the achievement and maintaining of therapeutic goals.Despide worldwide differences,norepinephrine is the vasoactive of choice in most countries but,whenever higher doses(>0.2 mcg/kg/min)are needed,a second vasoactive drug(vasopressin)is advisable.Hormonal therapy(desmopressin,corticosteroid and thyroid hormone)are suggested in all DBDs independently of hemodynamic instability.In the single patient,therapeutic regimen(imprimis vasoactive drugs)should be chosen also according to the potential organs retrievable(i.e.heart vs liver and kidneys).
