1 Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Malte Book Department of Anaesthesiology and Pain Medicine

2 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Vasoplegic syndrome after cardiac surgery Incidence 5% to 25% Levin et al. Circulation. 2009 Oct 27;120(17):1664-71 Hypotension Cardiac output or Systemic vascular resistence Requirement for fluid and vasopressors

4 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Methylene Blue, the magic bullet?

5 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Mode of action Inhibitor of NO Sythase NO scavenger Inhibitor of Guanulate Cyclase, cGMP cGMP mediated vasodilatation Interleukin-1 dependent Superoxide dependent

13 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Korean J Anesthesiol 2012 August 63(2): 142-148 Preoperative Prophylactic Methylene blue before CPB No differences in:MAP, MPAP, CI, PCWP, SVR Need for vasopressor/inotrope Less erythrocyte/platelet concentrates and FFP transfusion in the MB group

14 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Several studies showed potential benefit in the treatment or prevention of vasoplegic syndrome

15 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Indication No standard indication o Prevention of vasoplegic syndrome o Reversal of vasoplegic syndrome Inconsistant definition of vasoplegic syndrome

16 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Timing + dosing No standard timing of administration o Preoperative o Intraoperative o During CPB o Postoperative No standard dosing o 1.5 to 7.0 mg/kg bolus o Continious infusion

17 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Data quality + safety Few RCTs Mainly case reports/case series No phase 1 studies IMA contraction in clinically achieved concentrations Ulusoy et al. J Cardiothorac Vasc Anesth. 2008 Aug;22(4):560-4

18 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Recommendation No routine use of Methylene Blue Application within clinical trials Might be considered as final therapeutic option

19 Malte Book - Methylene Blue: Vasoplegic Syndrome Finally Resolved ? Inselspital, Bern University Hospital, Department of Anaesthesiology and Pain Medicine Alternative Arginin Vasopressin (AVP) o Up to 0.1 U/min o Higher number of RCTs investigated the clinical administration o Vasoplegia due to relative AVP deficiency Colson et al. Critical Care 2011, 15:R255 o Possibly causal therapy
