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.

Perioperative smoking causes acute changes in cardiopulmonary function that can have unfavorable implications for patients undergoing anesthesia. These cardiopulmonary effects are carbon monoxide and nicotine mediated changes in oxygen (O2) delivery and myocardial O2 balance. ⋯ Bringing about a decrease in postoperative pulmonary complications requires a much longer period of preoperative abstinence. Because the perioperative period is in many ways an ideal time to abandon the smoking habit permanently, anesthesiologists, in cooperation with other health professionals, can perhaps play a more active role in facilitating this process.

Review Case Reports
Anesthetic management of obstructive sleep apnea patients.
Presented in an illustrative case report and a review of the anesthetic management of obstructive sleep apnea patients. Preoperative evaluation should include a thorough airway evaluation and a comprehensive cardiovascular and pulmonary evaluation. With polysomnography, identification of the severity of sleep apnea can be idenified. ⋯ Opioids and sedatives should be avoided, as should other drugs that have central and sedating effects. Postoperative pain is effectively controlled with acetaminophen and topical anesthetic sprays. Postoperative monitoring for apnea, desaturation, and dysrhythmias is a necessity in sleep apnea patients.

Review Case Reports
Postextubation laryngeal spasm in an unanesthetized patient with Parkinson's disease.
We present a patient with Parkinson's disease who experienced laryngeal spasm after tracheal extubation without having been anesthetized. This patient's trachea was intubated because of respiratory arrest. We postulate that her postextubation laryngospasm was related to Parkinson's disease.
