To determine the sites and rates of the leakage of disposable breathing circuits. ⋯ Most disposable breathing circuits can be used safely for closed-circuit anesthesia, as the leakage volume is too small to be of clinical importance. The variation in the leakage rates stresses the importance of quality control of the connector seals.

To assess the resistance of a new endotracheal tube to penetration and ignition by a carbon dioxide (CO2) laser at a clinically relevant power setting. ⋯ The protective coating of the Xomed Laser-Shield II is laser-resistant, but the unprotected silicone proximal and distal to the cuff is laser-vulnerable and can, under certain conditions, promote a blowtorch phenomenon. This tube would be acceptable for use in oral and pharyngeal laser surgery, but we recommend its use only in well-ventilated areas, out of concern for exposure to the products of the pyrolysis of Teflon, specifically the development of polymer-fume fever.

To define the cardiovascular effects of rectal methohexital in children with normal cardiac function. ⋯ Rectal methohexital induces sleep in healthy pediatric patients with minimal cardiovascular side effects. The primary effects are increased HR and decreased SV.

Much has been written about Canada's health care system as all countries wrestle with rising health costs. Few, however, have attempted to describe the influence of a system of health care on a nonprimary care specialty such as anesthesia. The purpose of this review is to describe the Canadian system, contrast it with that of the United States, and outline the impact that Canadian Medicare has had on anesthetic practice. ⋯ Each provincial medical association is responsible for negotiating the fee schedules with the provinces on behalf of its members. Since these associations must respond to the majority of their members, it has been the perception of specialty groups such as anesthesia that the emphasis of allocations in recent years has been on primary care fields. Anesthetists have therefore found themselves increasingly involved with the collective negotiation process as an unwanted necessity of practice.(ABSTRACT TRUNCATED AT 400 WORDS)

Aneurysmal rupture represents the most common cause of subarachnoid hemorrhage. Approximately two-thirds of persons who experience a subarachnoid hemorrhage will die or become disabled. ⋯ The anesthetic management of these patients is reviewed, emphasizing principles relating to the facilitation of surgery--by optimizing operative conditions and minimizing the risks of intraoperative aneurysmal rupture or the aggravation of neurologic deficits--and to the provision of a smooth, stable recovery. Despite the disappointing overall prognosis following subarachnoid hemorrhage, adherence to these principles can optimize the outcome for those patients who reach the operating room.
