Anesthetic potential of the essential oils of Lippia alba and Lippia origanoides in Tambaqui juveniles/Potencial anestesico do oleo essencial de Lippia Alba e Lippia origanoides em juvenis de Tambaqui

The aim of this study was to investigate the anesthetic effect of the essential oils (EOs) of Lippia alba (citral and linalool chemotypes, EOLA-C and EOLA-L respectively) and Lippia origanoides (chemotype carvacrol, EOLO-Ca) on tambaqui (Colossoma macropomum) juveniles. The tested concentrations of...

Zusammenfassung:The aim of this study was to investigate the anesthetic effect of the essential oils (EOs) of Lippia alba (citral and linalool chemotypes, EOLA-C and EOLA-L respectively) and Lippia origanoides (chemotype carvacrol, EOLO-Ca) on tambaqui (Colossoma macropomum) juveniles. The tested concentrations of the L. alba and L. origanoides EOs were: 25, 50, 100, and 200 [micro]L/L. Time required to reach the stages of sedation, deep anesthesia, and recovery, as well as ventilatory frequency, were monitored for each EO concentration. The results indicated that all EO concentrations tested induced tambaqui anesthesia and that the ventilatory frequency was altered by the EOs. L. origanoides showed the shortest time to induce sedation and anesthesia, but had long recovery times. L. alba EO (citral 100 [micro]L/L and linalool 200 [micro]L/L) can be used to efficiently anaesthetise tambaqui juveniles with an efficient recovery. Key words: anaesthesia, carvacrol, citral, linalool, ventilatory frequency. O objetivo deste estudo foi investigar o efeito anestesico dos oleos essenciais (EOs) de Lippia alba (quimiotipos citral e linalool--EOLA-C e EOLA-L respectivamente) e Lippia origanoides (quimiotipo carvacrol- EOLO-Ca) em juvenis de tambaqui (Colossoma macropomum). As concentracoes testadas dos EOs de L. alba e L. origanoides foram: 25, 50, 100 ou 200 [micro]L/L. O tempo para atingir os estagios de sedacao, anestesia profunda, recuperacao e frequencia ventilatoria foram monitorados em cada concentracao de EO. Os resultados indicam que todas as concentracoes testadas dos OE induziram a anestesia do tambaqui e que a frequencia ventilatoria foi alterada pelos EOs. L. origanoides mostrou o tempo mais rapido para induzir sedacao e anestesia, mas os tempos de recuperacao foram longos. EO L. alba (citral 100 [micro]L/L e linalol 200 [micro]L/L) pode ser utilizado como anestesico em juvenis de tambaqui, pela eficiencia em anestesiar e recuperar. Palavras-chave: anestesia, carvacrol, citral, linalool, frequencia ventilatoria.
