Biography Historical Article[Nitrous oxide in dental anesthesia: facts about its introduction in Spain].
After a free period of twenty years the interest for using nitrous oxide in suppressing pain related to dental surgery has increased since the end of the sixties of the last century. In this work we present the result of our investigations on the person who must be considered the introducer of this technique in Spain: José Meifrén Alfares, odontologist at Barcelona.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study of radial and cubital arterial catheterization].
In this prospective study we evaluated catheterization of the cubital artery as an alternative to cannulation of the radial artery. Seventy six surgical patients were randomly allocated into two groups of 38 patients according to the intention to catheterize the cubital or the radial artery. ⋯ The qualification of the technician, the arterial blood pressure and the anatomic characteristics of the forearm did not influence the results. We conclude that whenever the cubital arterial pulse is appropriately perceived, catheterization of this artery is a good alternative to radial catheterization.

[Intrinsic PEEP as a ventilation complication after pneumonectomy].
We report the case of a female patient who developed a clinical picture characterized by hemodynamic deterioration, bradycardia and asystole due to pulmonary hyperinsufflation (documented by X-ray examination) during the immediate postoperative phase of a right pneumonectomy. Occlusion of the respiratory limb of the respirator was followed by a positive pressure at the end of the respiration (PEEP) suggesting the presence of an intrinsic PEEP independent of the respirator. Application of a PEEP to the respirator induced a radiologic improvement. The mechanisms by which an intrinsic PEEP may develop are discussed.

Case Reports[Intracardiac knotting of a Swan-Ganz catheter. Detection using intraoperative trans-esophageal echocardiography].
Transoesophageal echocardiography is a new technique that allows continuous and noninvasive assessment of cardiac function during surgery. More recently this technique is being used to detect the presence of external objects into the cardiac cavities. We report a case of Swan-Ganz catheter knotting confirmed by this echocardiography technique. ⋯ During extracorporeal circulation the catheter was withdrawn through a right auriculotomy. Monitoring with a Swan-Ganz catheter, as other invasive monitoring techniques, is followed by a certain degree of complications which should be avoided by a careful manipulation. Echocardiography is a valuable diagnostic procedure to identify the position of monitoring catheters into the cardiac cavities.

Comparative Study Clinical Trial Controlled Clinical Trial[Effect of an intravenous nitroglycerin bolus on the hemodynamic impact of laryngoscopy and intubation].
The aim of this study was to evaluate the effectiveness of intravenous administration of a single dose of nitroglycerin in lessening the hemodynamic effects induced during laryngoscopy and tracheal intubation. In an initial subset of 8 patients we verified that the hemodynamic changes after an intravenous dose of 2, 5, or 10 micrograms/kg of nitroglycerin were comparable. The study included 30 patients with a good clinical condition who were anesthetized with fentanyl, thiopental sodium and succinylcholine. ⋯ Increase in diastolic blood pressure was also lower in nitroglycerin treated patients but this difference was only present during laryngoscopy. There were no significant heart rate differences among the two groups of patients. It is concluded that a single intravenous dose of 2 micrograms/kg of nitroglycerin was able to lessen the increase in blood pressure induced by laryngoscopy and tracheal intubation without deleterious effects.
