Case ReportsBilateral tension pneumothoraces following jet ventilation via an airway exchange catheter.
We report a case involving a 55-year-old man who had a recent resection of tracheal carcinoma and tracheal reanastomosis. He subsequently developed tracheomalacia and anastomotic dehiscence requiring airway stenting via an armored endotracheal tube (ETT). Placement of the armored ETT was technically difficult. ⋯ The patient was quickly recovered, stabilized, and later discharged after a prolonged intensive care unit (ICU) course. We review the recommendations for jet ventilation via airway exchange catheters, common problems during this technique, and potential methods for avoiding these problems. The risk of barotrauma and pneumothoraces during jet ventilation via an airway exchange catheter should be kept in mind.

Comparative StudyEarly neuropsychological dysfunction in elderly high-risk patients after on-pump and off-pump coronary bypass surgery.
Advanced age is associated with systemic atherosclerosis and is a risk factor for neurological dysfunction after coronary artery bypass grafting (CABG). However, few studies have investigated early neurological dysfunction after off-pump CABG in elderly patients. ⋯ Off-pump CABG reduced postoperative NP dysfunction in elderly patients with severe systemic atherosclerosis compared to on-pump CABG.

Randomized Controlled TrialThe use of droperidol decreases postoperative nausea and vomiting after gynecological laparoscopy.
We evaluated whether or not routine prophylaxis with 2.5 mg of droperidol would efficiently prevent postoperative nausea and vomiting (PONV). Fifty-two patients scheduled for elective gynecological laparoscopic surgery were eligible for this study. Anesthesia was induced using propofol, fentanyl, and vecuronium, and maintained with sevoflurane in nitrous oxide, fentanyl, and vecuronium. ⋯ Episodes of nausea and vomiting and the need for metoclopramide in group 1 were lower than in group 2, though the total fentanyl dose in group 1 was higher than in group 2. There were no differences in the need for analgesics between the groups. The use of 2.5 mg droperidol safely decreased PONV after gynecological laparoscopy.

The skin-traction method increases the cross-sectional area of the internal jugular vein by increasing its anteroposterior diameter.
We developed a novel "skin-traction method" in which the puncture point of the skin over the internal jugular vein (IJV) is stretched upward with several pieces of surgical tape in the cephalad and caudad directions to facilitate cannulation of the IJV. We investigated whether this method increases the cross-sectional area of the IJV. ⋯ This method significantly increased the cross-sectional area of the RIJV by increasing the anteroposterior diameter of the RIJV. Even in the flat position, this method was almost as efficacious as the Trendelenburg position. This method thus appears to facilitate IJV cannulation.
