Randomized Controlled Trial Clinical TrialReinforcement of spinal anesthesia by epidural injection of saline: a comparison of hyperbaric and isobaric tetracaine.
An epidural injection of saline was reported to extend spinal anesthesia because of a volume effect. The aim of this study was to evaluate the influence of the baricity of spinal local anesthetics upon the extension of spinal anesthesia by epidural injection of saline. ⋯ In this study, 8 ml of epidural saline extended spinal analgesia. However, there was no difference between the augmenting effect in isobaric and hyperbaric spinal anesthesia. We conclude that the reinforcement of spinal anesthesia by epidural injection of saline is not affected by the baricity of the spinal anesthetic solution used.

Randomized Controlled Trial Clinical TrialNicardipine versus lidocaine for attenuating the cardiovascular response to endotracheal intubation.
The aim of this study was to compare the efficacy of nicardipine and lidocaine in attenuation of cardiovascular responses to endotracheal intubation. ⋯ Nicardipine can be used as an alternative to lidocaine in attenuation of cardiovascular response to tracheal intubation in patients without ischemic heart disease.
