However, the respective efficacy of these techniques has not been concluded. Sconzo et al. indicated that endotracheal tube (ETT) cuff might serve as a reservoir for local anesthetic. Alkalizing and warming are two techniques frequently used to increase in the proportion of uncharged drugs available. Matias indicated that alkalization could prompt a 63-fold increase of the rate of diffusion of lidocaine across the ETT cuff. Huang et al. also observed that alkalization together with warming could achieve a 118-fold increase further. However, the in vivo effects of ETT-cuff lidocaine have not been studied. | lld:pubmed |
