Four groups were formed after randomization : 1 ) RIPC applied during propofol anesthesia ( RIPCprop , n = 12 ) , 2 ) RIPC applied during sevoflurane anesthesia ( RIPCsevo , n = 12 ) , 3 ) propofol anesthesia without RIPC ( CONTROLprop , n = 12 ) , 4 ) sevoflurane anesthesia without RIPC ( CONTROLsevo , n = 12 ) .
