T-cell lymphoma is the fastest growing non-Hodgkin's lymphoma occurring in children. Its clinical presentation is frequently abrupt, and total tumor mass can double every few days. ⋯ What information do we need, and how recent should it be? This case shows that recent diagnostic imaging studies not showing the presence of a mediastinal lymphoma can be misleading. It provides a strong warning to all anesthesiogists involved in ambulatory anesthesia.

The dorso-radial aspect of the wrist and hand is a common location for intravenous (IV) cannulation prior to anesthesia. The sensory branch of the radial nerve lies superficially in this area, and it can be injured during routine insertion of IV catheters. In this case, the nerve was lacerated during insertion and a painful neuroma developed after elective surgery and anesthesia. Knowledge of this complication may help with its recognition and treatment.

Randomized Controlled Trial Comparative Study Clinical Trial
Hemodynamic effects during induction, laryngoscopy, and intubation with eltanolone (5 beta-pregnanolone) or propofol. A study in ASA I and II patients.
To evaluate the cardiovascular changes following induction of anesthesia, laryngoscopy, and intubation in patients receiving a bolus dose of either eltanolone or propofol. ⋯ Patients receiving either eltanolone or propofol showed similar cardiovascular changes to induction of anesthesia, although there were greater increases in arterial pressure and HR in those patients receiving eltanolone.

Randomized Controlled Trial Comparative Study Clinical Trial
Study of the optimal duration of preoxygenation in children.
To determine the optimal length of preoxygenation in children. ⋯ 2 minutes of preoxygenation in children can provide the maximum benefit of denitrogenation and achieve 2 minutes of safe apea. 95% and 99% confidence intervals were 69 to 100 and 59 to 100, respectively. Succinylcholine had only a slight effect on the safe apneic period.

In the last decade, anesthesiologists have become increasingly involved in administering regional eye blocks, while providing care for patients undergoing ophthalmic surgery. This article describes the two major approaches to regional eye block, namely retrobulbar and peribulbar, with special consideration given to relevant orbital anatomy and technical guidelines. Potential complications, ocular and systemic, with their risk factors, are reviewed. Anesthesiologists wishing to acquire skill in administering safe regional blockade are encouraged to familiarize themselves with regional anatomy and specific guidelines suggested herein.
