Abstract:
Different effects of thiopental, propofol and sevoflurane on platelets have been reported. Patients undergoing thyroid surgery were anaesthetized with thiopental-fentanyl-sevoflurane (n = 11) or propofol-fentanyl-sevoflurane (n = 9). Platelet aggregation and thromboxane A2 generation were studied at baseline, and at the end of anaesthesia induction and surgery. Dose-response experiments were also performed in vitro with single agents. Thiopental-fentanyl-sevoflurane significantly reduced collagen-induced aggregation by the end of induction, while ADP-induced aggregation and thromboxane generation were unaffected. Propofol-fentanyl-sevoflurane had no effect on platelets. Thiopental dose-dependently inhibited platelets in vitro, while fentanyl or propofol did not. In conclusion, thiopental reduces platelet function both ex vivo and in vitro and propofol might be considered haemostatically safer.
