[Relationship between mixed venous saturation and cardiac index, hemoglobin and oxygen consumption in aortic surgery].
Mixed venous oxygen saturation (SvO2) depends mainly on four variables: cardiac index (CI), hemoglobin concentration (Hb), arterial oxygen saturation (SpO2) and oxygen consumption (VO2). Our aim was to study the correlation between each of these variables and SvO2 during abdominal aortic surgery, a situation which is of special interest because of associated hemodynamic and metabolic variations and the high risk of cardiovascular events. ⋯ Monitoring SvO2 in patients undergoing aortic surgery is useful for detecting potentially prejudicial variations in cardiac output or hemoglobin concentration.

Case Reports[The incidence of intraoperative conciousness in emergency surgery and its possible relation to the post-traumatic stress syndrome. Presentation of three cases].
Intraoperative awakening and recall of specific events is a rare complication (0.2 to 1.3%) of surgery. The possibility of developing serious psychiatric complications, such as posttraumatic stress disorder (PTSD) makes the prevention and detection of intraoperative awareness a subject of special interest. We describe our experience with three patients in whom awareness was detected during emergency surgery under general anesthesia. ⋯ Efforts to decrease the incidence of episodes of intraoperative awakening with specific recall must be based on clinical observation and exhaustive monitoring of the patient, including anesthetic gases, given that no ideal method of monitoring depth of anesthesia exists. Cases should be detected in the first few days after surgery by means of a specific test. Likewise, possible causes for the episode should be explained to the patient, who should be followed for six months so that early diagnosis of PTSD or other psychiatric complications can be made.

[Books on anesthesiology and resuscitation published in Spain. An approach to their study].
Few authors have examined the publication of medical books. Our aim was to analyze the nature of books published in Spain on anesthesiology and recovery. ⋯ Spanish publication of books on anesthesiology and recovery has increased in recent years. Most books are translations usually from English. Spanish ISBN agency data, although it has limitations, can be useful for locating books published in Spain on anesthesiology and recovery. It would be useful to introduce keywords into the ISBN data base so that books on specific subjects could be classified and retrieved.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of lidocaine and urapidil for prevention of hemodynamic response to tracheal intubation in patients in general good health].
To compare the efficacy of endovenous administration of 0.5 mg/kg-1 of urapidil to 1 mg/kg-1 of lidocaine for attenuating hemodynamic response to laryngoscopy and tracheal intubation. ⋯ In healthy ASA I and II patients with normal blood pressure, a dose of 1 mg/kg-1 of lidocaine provided better protection against the hemodynamic response to laryngoscopy and tracheal intubation than does 0.5 mg/kg-1 of urapidil.

Clinical Trial[Obstetrical anesthesia in 15 women with myasthenia gravis].
To report our experience in managing anesthesia during obstetric delivery of women with myasthenia gravis (MG) and to review the anesthetic technique of choice for vaginal or cesarean delivery in such cases. ⋯ Continuous lumbar epidural anesthesia is the technique of choice for vaginal as well as cesarean deliveries. The combination of opioids and local anesthetics is considered particularly beneficial for patients, as it allows the motor blockade to be decreased. General anesthesia is only indicated when there is bulbar involvement. Short-acting non depolarizing agents, among them atracurium Besilate, are the muscle relaxants of choice. Succinylcholine is contraindicated. Thanks to current optimization of anesthetic and recovery techniques and administration of non depolarizing muscle relaxants with neuromuscular monitoring, the prognosis for pregnant MG patients has improved considerably.
