To define the depth of the thoracic epidural space in the paramedian axis. ⋯ Body weight, body mass index, and anatomical levels determine the paramedian thoracic epidural depth. The greater the patient's weight and the higher the puncture level, the deeper the thoracic epidural space from the body surface.

The aim of this study was to test the hypothesis that the intraoperative pharyngeal temperatures obtained on the perilaryngeal airway (PLA), a novel airway device with a larger pharyngeal cuff (when inflated) than the laryngeal mask airway, are similar to tympanic membrane core temperatures. ⋯ These data suggest that the PLA can be adapted to monitor core temperature reliably.

Randomized Controlled Trial
Effect of catheter site on the agreement of peripheral and central venous pressure measurements in neurosurgical patients.
Previous studies suggest a correlation of central venous pressure (CVP) with peripheral venous pressure (PVP) in different clinical setups. The aim of this study was to investigate the effect of measurement site on PVP and its agreement with CVP in patients undergoing general anesthesia. ⋯ Peripheral venous pressure measurement may be a noninvasive alternative for estimating CVP in patients undergoing elective neurosurgical operations. Measuring PVP from hand dorsum does not interfere with the agreement of CVP and PVP.

To investigate the difference of regional cerebral oxygen saturation (rSo2) decrease in response to the decrease in mean arterial blood pressure (MAP) in young and elderly patients. ⋯ After propofol induction, there was no difference between young and elderly patients in rSo2 decrease in response to the decrease in MAP.

The objective of this study was to evaluate the effectiveness of a modified Macintosh blade for reducing the chances of directly contacting the teeth and providing a satisfactory laryngoscopic view during laryngoscopies by novice laryngoscopists. ⋯ The modified Macintosh blade used in this study proved to be a useful device for training novice laryngoscopists with respect to procedure effectiveness and patient safety.
