title: Comparison of the effects of desflurane and sevoflurane on the expression of platelet surface glycoproteins in unstimulated and adenosine diphosphate-induced platelets in vitro.
abstract: OBJECTIVE
  To compare the effects of one minimum alveolar concentration (MAC) desflurane and sevoflurane on the expression of CD42b (glycoprotein [GP] Ib), CD41 (GPIIb), CD61 (GPIIIa), CD62P (P-selectin), and CD63 in both unstimulated and adenosine diphosphate (ADP)-stimulated platelets in vitro.
  
  
  METHODS
  University laboratory.
  
  
  METHODS
  15 healthy volunteers.
  
  
  METHODS
  Platelet-rich plasma was obtained and divided into three groups: platelet-rich plasma exposed to air (group 1); air plus one MAC desflurane (6% vol; group 2), and air plus one MAC sevoflurane (2% vol; group 3), for 40 minutes. Percentage of antigen-positive cells (%(+)) mean channel fluorescence (MCF(Sigma)), and index of platelet activation for positive platelets (IPA(+)) as expression markers for GPIb, GPIIb, GPIIIa, P-selectin, and CD63, were measured.
  
  
  RESULTS
  In unstimulated platelets, expression markers for GPIIb and GPIIIa were significantly lower in groups 2 and 3 than group 1 (P < 0.001). P-selectin expression markers were significantly higher in group 2 than in group 1 or group 3 (P < 0.016). CD63 expression markers were significantly lower in group 3 than group 1 (P < 0.016). In ADP-stimulated platelets, expression markers for all glycoproteins were significantly higher in all groups.
  
  
  CONCLUSIONS
  Neither one MAC desflurane nor sevoflurane showed any significant change in ADP-stimulated platelets compared with the control group.
