In the use of 8% lidocaine pump spray as a lubricant on the Trachlight wand, its print mark was found to have dissolved. We therefore studied this dissolving effect on the print mark with three different types of lubricant (2% lidocaine jelly, 8% lidocaine pump spray and glycerin). ⋯ The manufacturer recommends that any topical anesthetics or other active ingredients should not be contained in a lubricant used on the Trachlight wand. We conclude that lidocaine pump spray should not be used as a lubricant on the Trachlight wand.

Randomized Controlled Trial Comparative Study Clinical Trial
[Assessment of preoperative anxiety in patients entering the operating room on foot using state-trait anxiety inventory].
The purpose of this prospective study was to assess the effect of walking into the operating room on preoperative anxiety level. Sixty non-premedicated patients scheduled for elective surgery were randomly divided into two groups based on how they were transported into the operating room. ⋯ STAI values were not increased in the operating room as compared to the day before surgery for either group and did not differ between groups, though they showed a high level of anxiety throughout the preoperative period. We conclude that walking into the operating room has no significant influence on preoperative anxiety level.

Cardiology consultations are often requested preoperatively for patients with cardiovascular problems. However, there are frequently differences in the evaluation of preoperative cardiac risks among cardiologists, surgeons and anesthesiologists. ⋯ The survey indicates a lack of interaction with anesthesiologists and insufficient information on the surgical procedures and anesthesia for cardiologists to assess compromising cardiac risks. In addition, many cardiologists suggested that exercise tolerance required for surgical procedures should be 7 METs or more for surgical patients.

An epidural catheter must be placed in epidural space correctly to give sufficient epidural anesthesia for patients. Recently, as a technique to confirm the catheter placement, electrical stimulation of epidural nerve using an inserted epidural catheter was introduced. This study was conducted to evaluate the reliability of this simple technique in 13 patients. ⋯ X-ray examinations revealed that the tip of catheter placed at the vertebral level corresponded with the spinal segmental level where muscle movement occurred. Our study demonstrates that nerve stimulation can be a reliable method to confirm epidural catheter placement. Our results also suggest that the position of catheter tip can be estimated easily using this technique.

Bispectral index (BIS) is a processed EEG parameter for assessment of hypnotic effects of anesthetics. We studied whether BIS monitoring can improve recovery from propofol anesthesia and decrease the total amount of propofol needed. Forty-six patients without hypertension and obesity were studied. ⋯ There were no significant differences in the incidence of intraoperative responses between the two groups. BIS monitoring decreased the total amount of propofol and led to immediate recovery after propofol anesthesia. These findings indicate that the use of BIS monitoring may be useful in controlling the infusion rate of propofol during surgery.
