Randomized Controlled Trial Clinical TrialHemodynamic and catecholamine responses during tracheal intubation using a lightwand device (Trachlight) in elderly patients with hypertension.
Tracheal intubation using a lightwand device (Trachlight) should minimize hemodynamic change by avoiding direct-vision laryngoscopy. We evaluated hemodynamic and catecholamine responses during tracheal intubation using a Trachlight in elderly patients with hypertension. ⋯ A lightwand has no advantage over a laryngoscope in terms of hemodynamic and plasma catecholamine responses to tracheal intubation in elderly patients with hypertension, despite a shorter intubation time.

Randomized Controlled Trial Clinical TrialReduction of potential respiratory pathogens by oral hygienic treatment in patients undergoing endotracheal anesthesia.
This study was conducted to evaluate the usefulness of mechanical and chemical prophylactic oral cleansing treatments for reducing potential respiratory pathogens existing in the oral cavity. ⋯ The combination of mechanical and chemical oral cleansing resulted in a significant reduction of potential respiratory pathogens in the oral cavity.

Randomized Controlled Trial Clinical TrialHemodynamic and bispectral index responses to tracheal intubation during isoflurane or sevoflurane anesthesia.
The effects of volatile anesthetics on change in the bispectral index (BIS) due to tracheal intubation are unclear. We investigated hemodynamic and BIS responses to intubation during isoflurane or sevoflurane anesthesia. ⋯ Anesthesia with 2 MAC of isoflurane and sevoflurane was effective to suppress the change in BIS due to intubation but was not sufficient to prevent changes in hemodynamic responses.

Randomized Controlled Trial Comparative Study Clinical TrialTemperature and humidity of the Dräger Cato anesthetic machine circuit.
The Dräger Cato anesthetic machine (Dräger, Lübeck, Germany) effectively humidifies and warms anesthetic gases, because it has a built-in hotplate to heat the breathing system, and expired gas passes through the CO2 absorbent three times during one breath. In the present study, we measured the temperature and absolute humidity (AH) of the anesthetic circuit in the Dräger Cato machine with and without heat moisture exchangers (HME), and compared them with those in another anesthetic machine, the Aestiva/5 (Datex-Ohmeda, Helsinki, Finland). ⋯ The present study indicates that the Dräger Cato machine was more effective in warming and humidifying respiratory gas than the Aestiva/5, and that Aestiva/5 without HME does not reach the optimal temperature and humidity ranges, even if minimal flow anesthesia (0.51 x min(-1)) is performed.
