Randomized Controlled Trial Comparative Study Clinical Trial[Gynecologic laparoscopy with or without curare].
To assess physiological changes and operating conditions during general anaesthesia with or without neuromuscular blockade in patients undergoing gynaecologic laparoscopy. ⋯ Neuromuscular blockade influences neither most of the clinical haemodynamic and respiratory changes induced by pneumoperitoneum for gynaecologic laparoscopy not the operating conditions.

Comparative Study Clinical Trial Controlled Clinical Trial
[Evaluation of the usefulness of the laryngeal mask for general anesthesia in eye microsurgery--preliminary results].
This prospective study was designed to compare intraocular pressure changes and haemodynamic response to insertion of either a laryngeal mask or an orotracheal tube during general anaesthesia for cataract surgery. ⋯ The results show that using LMA in microsurgery during general anaesthesia is more advantageous and safer for patients in comparison with tracheal intubation.

Animal studies show that airway receptors responsible for eliciting respiratory protective reflexes are not uniformly distributed in the airways. Based on this information, it is possible that the protective reflex responses to airway irritation in humans may vary, depending on the site of stimulation. The purpose of this study is to examine whether the protective reflex responses evoked from the larynx are different from those evoked from the lower airways and to see how change in depth of anesthesia modifies the protective reflex responses evoked from individual sites. ⋯ The respiratory reflex responses evoked by injection of water vary, depending on the site of stimulation. The incidence of various reflex responses was not affected by the changing depth of anesthesia. The sensitivity to airway irritation seems to be greater at the larynx and trachea than at the more peripheral airways.

Mental status changes were assessed and compared in 172 general surgical and orthopedic patients and 190 nonsurgical patients, all aged 55 and over, during a 10-month period. Assessments included a structured psychosocial questionnaire and standardized tests of cognition, affect, and function. The relationship of surgery, type of surgery, age, gender, and postoperative delirium to long-term postoperative decline was evaluated. ⋯ Hierarchical multiple regression analyses assessed the unique contributions of demographic and surgical variables to cognitive, affective, and functional change. None of the independent variables tested made a significant contribution to changes from baseline to long-term follow-up. The findings may be due to the physical and psychological health of this sample, and replication of this work in more impaired populations may be productive.

As a result of more offensive therapeutic measures and the given abilities of modern medicine and the increasing number of geriatric patients who are characterized by multimorbidity, more perioperative complications, in particular those of cardiac origin, can be expected. As in any other medical discipline, the safety of anaesthesiological care of the patient very much depends on the individual professional qualification and competence of the physician. For the field of anaesthesiology it can be concluded that it is necessary to tackle the specific problems of this risk group in order to reduce the rate of complications to a minimum. ⋯ Three main symptoms--increasing oxygen uptake (as a product of pain or shivering), hypoventilation and hypoxaemia--should be avoided in the postoperative period. Therefore, respiratory insufficiency should be diagnosed without fail by respiratory monitoring. If required, artificial ventilation must be continued, with particular attention being given to circulatory effects during artificial ventilation and weaning from the ventilator.
