Historical Article[The introduction of chloroform anesthesia in Madrid. Notes for studying its history].
Until present, the introduction of chloroform anesthesia in Madrid has not been specifically studied by any author. Therefore, knowledge of the events related to this happening is lacking. We have studied this chapter of our history by analyzing primary documents and articles published at the daily press, political press, and scientific journals of Madrid during 1847 to 1848. ⋯ Based on the present bibliographic material we could establish a chronologic report of all surgical interventions using chloroform that were performed in Madrid. We conclude that albeit surgeons in Madrid were not the first to use chloroform in Spain, they were, however, the ones who most extensively used it. Their contribution was of relevance in the settlement of the new anesthetic agent in Spain.

Comparative Study Clinical Trial Controlled Clinical Trial[Pressure changes in the pneumoballoon of several endotracheal tubes after the administration of nitrous oxide].
We compare the degree of nitrous oxide diffusion in three types of endotracheal tubes available in the market, by means of continuous monitoring of the pressure attained at the pneumoballoon. Among the systems designed to impede or to minimize nitrous oxide diffusion, we have used in this study the so called "rediffusion system". ⋯ We believe that during anesthesia with nitrous oxide the pneumoballoon pressure should be monitored or systems that avoid diffusion of this inhalational agent should be inserted. Our results indicate that endotracheal tubes equiped with "rediffusion system" are effective in impeding diffusion of the inhalational agents.

[Selective right bronchial intubation using tracheal tubes under fibroscopic guidance].
We have evaluated the technique of right bronchial intubation for selective right pulmonary ventilation using one lumen tracheal tubes as an alternative to double lumen tubes. We studied 20 patients ASA II-III with a relatively preserved pulmonary function who were programmed for left thoracotomy. We used Shiley nr. 9 or Mallinckrodt nr. 11 tubes. ⋯ In three patients (15%) blinded placement of the tube was appropriate and in 4 patients (20%) fibroscopic replacement of the tube was required. In the remaining 13 patients (65%) placement of the tracheal tube was considered incorrect: tube rotation in 7 cases, upper placement of the Murphy's hole with respect to the origin of the superior lobar bronchus in 4 cases, and excessive distal placement of Murphy's hole with respect to the superior lobar bronchus in 2 patients. Complications related with the incorrect position of the tube were: leaking of gas into the left bronchium in 5 patients (25%), displacement of the tracheal tube into the main left bronchus requiring withdrawal of the tube to the trachea in one case (5%), hypoxemia (saturation of O2 lower than 90%) in spite of ventilation with FiO2 = 1 in two patients, moderate hypercapnia in three cases, and atelectasis of the right superior lobe during the postoperative phase in three patients (15%).(ABSTRACT TRUNCATED AT 250 WORDS)
