Randomized Controlled Trial
Experience of anesthesiologists with percutaneous nonangiographic venous access.
To compare percutaneous nonangiographic insertion of a venous access device with a standard surgical cutdown insertion technique. ⋯ The simplified, percutaneous, nonangiographic technique is as effective as the traditional venous cutdown technique and can be safely done by surgeons as well as by experienced physicians who are not surgeons.

Clinical Trial
How often should we perform arterial blood gas analysis during thoracoscopic surgery?
To continuously measure arterial blood gases (ABGs), to calculate the percentage of anticipated changes over time, and to develop recommendations for sampling frequencies of arterial blood gases in patients undergoing thoracoscopic surgery. ⋯ Current standards to monitor arterial blood gases are not sufficient to detect and prevent hypoxemic events during thoracoscopic surgery with one-lung ventilation. Intermittent arterial blood gas analyses must be performed more frequently, up to every 10 minutes, to detect changes of 20% in arterial partial pressure of oxygen.

Case Reports
Soft palate perforation during orotracheal intubation facilitated by the GlideScope videolaryngoscope.
We report a case in which a videolaryngoscope was used to facilitate endotracheal intubation in a patient with a large exophytic mass involving the right supraglottis. After intubation, it was noted that the soft palate had been perforated by the styletted endotracheal tube. The defect closed spontaneously postoperatively within 9 days.

Randomized Controlled Trial
The analgesic efficacy of preoperative versus postoperative lornoxicam in varicocele repair.
To determine whether intravenous injection of lornoxicam 30 minutes before skin incision provides better pain relief after varicocelectomy than postoperative administration of lornoxicam. ⋯ Intravenous lornoxicam administered before surgery has a better analgesic effect for varicocelectomy than when administered postoperatively.

Randomized Controlled Trial
Clinical analgesic efficacy and side effects of dexmedetomidine in the early postoperative period after arthroscopic knee surgery.
To determine the analgesic efficacy of dexmedetomidine in the early postoperative period. ⋯ Dexmedetomidine provides a modest analgesic effect after knee arthroscopy, but the side effects of this drug, such as hypertension and bradycardia, may restrict the use of large bolus doses.
