[Robert R. Macintosh and Spain: a productive relationship].

Through his visit to Spain in 1946, Robert R. Macintosh exercised considerable influence on the introduction and development of modern anesthesia in this country. This paper reviews the technical advances Mackintosh introduced and considers how his visit was one of the most important factors in unleashing the development of the profession here. Also reviewed are the other visits Mackintosh made in the course of his career. Those trips were less important, with the exception of a 1937 visit that inspired the design of the Oxford vaporizer, a technical concept based on simplicity, safety and the anesthesiologist's experience.

[A new toy: upswing in curare use in Spanish anesthesia].

The introduction of curare for general anesthesia by Harold Griffith in 1942 was one of the most important moments in the development of anesthesiology. However, several years passed before curare came to be used in Spain. We review the early application of curare and the role played by Robert Macintosh, Professor of Anaesthesia at Oxford, in introducing the drug to Spain.

[Anesthetic management of a patient with dystrophic ampullar epidermolysis].

We report the clinical case of a 56 years old male suffering dystrophic ampullar epidermolysis. He underwent brachial plexus blockade to remove a right hand tumor. The patient presented bilateral pseudosyndactylia, flexion retraction of the left hand, and erosive lesions in the inferior extremities, forearm, and trunk interfered monitorization and venous catheterization. Cutaneous friction or trauma should be carefully avoided since in this patient might produce detachment of the epidermis and subsequent ampullar formation. Cutaneous electrodes without adhesive components, padded sphygmomanometers, ear pulsimeter, and venous catheter sutured to the skin were used during monitorization. Anesthetic management of patients with dystrophic ampullar epidermolysis should consider careful airway manipulation, reduction of mucocutaneous contacts, prevention of pressure or friction skin trauma, appropriate electrolyte and plasma volume reposition, and use of nonadhesive material. To avoid airway manipulation regional anesthesia should be considered in patients with ampullar epidermolysis. We recommend regional anesthesia with ketamine.

[Tracheal injury during transhiatal esophagectomy without thoracotomy. Anesthesiologic management].

A patient with carcinoma of the lower third of esophagus suffered an extensive tracheal tear during transhiatal esophagectomy without thoracotomy, with severe impairment of ventilatory and hemodynamic status. A right thoracotomy was required for the repair of the tracheal lesion, which extended to the origin of left bronchus. During the maneuvers for bronchial intubation, the hypoxia worsened and cardiac arrest caused by ventricular fibrillation appeared. The arrhythmia was reverted. Operative mortality of transhiatal esophagectomy without thoracotomy is 8%. Pneumothorax is the most common operative complication. Tracheal laceration is reported in 1% of cases; usually it is not severe and is easily treated, although it can have significant severity and result in death as in the present case. After the operation, the patient persisted hemodynamically unstable, developing a new gasometric deterioration and bilateral pleural effusion, with impairment of coagulation. The patient died 39 hours after operation. The anesthetic management of peroperative tracheal tear is reviewed.
