One of the controversial subjects in anesthesia has been that of the incidence and specificity of neurological sequelae attributable to spinal anesthesia.1Various complications are cited by opponents of the method. These include headache, diplopia, backache, paresthesias in the legs, paralysis or weakness of muscles, usually in the legs, and infection either localized or diffuse in the form of meningitis. Beginning in 1948, a serious attempt was made to follow each patient who received spinal anesthesia at the Hospital of the University of Pennsylvania, not only in the immediate postoperative period but also for periods of six months to a year afterwards. To date, 90% of some 6,000 patients have been successfully contacted in this fashion. Our experience suggests that attention to details of technique will result in a much lower incidence of neurological sequelae than is suggested in the reports cited. The technique of spinal anesthesia can be

In anesthesiology there is a continuing healthy criticism of the agents and techniques used to achieve practical and safe conditions for surgical operations. This criticism arises both from within the ranks of the specialty and from outside. Hardly a drug or method is free of major disadvantages. Recent reports have described what seems to be an increasing incidence of cardiac arrest under anesthesia.1General anesthesia and particularly the employment of multiple agents have been blamed in part for this increased mortality. We hear that ether is not the safe agent it once was thought to be2and that curare may possess an inherent toxicity.3Spinal anesthesia, an anesthetic technique with great advantages for the patient, surgeon, and anesthetist, is relatively free from the criticism of toxicity and the mortality associated with general anesthesia; on the other hand, the great hazard of spinal anesthesia in the minds of

Most physicians can safely administer certain general and local anesthetics if they are willing to acquaint themselves with the principles involved. Knowledge of resuscitation is also essential. Instruction in the preparation of the patient is offered, and the three common anesthetic technics (inhalation, regional, intravenous) are considered here.

Summary The postanesthetic recovery room records of 14,436 patients given general anesthetics have been surveyed to obtain information on the incidence of and etiologic factors in the development of emergence excitement. The incidence of excitement was 5.3 per cent in the entire group. The highest incidences of excitement were correlated with the youth of the patient, the excellence of his health, barbiturate and scopolamine preanesthetic medication, cyclopropane or ether anesthesia, and operative procedures associated with pain or emotional stress. The addition of a narcotic to the preanesthetic medication reduced the occurrence of emergence excitement. The significance of the results of the survey and a suggested regimen of therapy are discussed.
