Evaluation of manually operated self-inflating resuscitation bags.
Eight resuscitators were tested, of which five have recently been improved by the manufacturers (Air Shields Ambu, Danish-made Ambu, Pulmonator, Laerdal Resusci II, and Air Viva). One had an addition made to improve its oxygen (O2)-delivering capacity (Hope bag fitted with Blount collar) and two were new, the Air Bird, with and without high O2-concentration delivering system. ⋯ However, some still malfunction, some do not deliver adequate O2 concentrations for hospital use, and there is still a great variability in their performance. In some, freezing at low temperatures or clogging of valves with mucus are special hazards.

Malignant hyperthermia associated with enflurane anesthesia: a case report.
Malignant hyperthermia syndrome associated with various anesthetic agents has been well documented, but none has been reported with enflurane (Ethrane). This particular case is the first involving exposure for the second time to enflurane anesthesia after a six-month interval in which malignant hyperthermia resulted. ⋯ However, with the abnormal production of heat in the soda lime canister with tachycardia, tachypnea, rapidly rising body temperature and hypertonicity of skeletal muscles during anesthesia one should suspect malignant hyperthermia. The treatment of malignant hyperthermia involves cooling procedures, correction of acidosis, use of steroids and procainamide, and acetaminophen to facilitate lowering the body temperature.

Comparative StudyA survey of the practice of anesthesiology in the U.S.--1972.
During the calendar year 1972, 46 hospitals throughout the U. S. A. participated in a survey of their anesthesia practices, using simple criteria from the "Standards of Patient Care in Anesthesiology." Eight "yes-no" questions were asked: 1. ⋯ Did the patient live? Data from 208,868 anesthetic procedures indicated an overall mortality rate of 1.1 percent. Although affirmative responses in excess of 73 percent were noted to each condition of practice, only 50.9 percent of the cases received such a response to all five practice criteria; that is, questions 1, 2, 3, 5, and 7. A sample survey of data indicated a comparatively similar standard of practice between simple and complex operative cases.
