Comparative Study
[Effects of laryngeal mask airway on circulation and on incidence of postoperative sore throat and hoarseness].
We studied the effects of laryngeal mask airway (LM) insertion on circulation and on the incidence of postoperative sore throat or hoarseness as compared with tracheal intubation in 50 pediatric patients. LM insertion caused less change of heart rate and systolic blood pressure than tracheal intubation. The incidence of postoperative sore throat and hoarseness was less in the patient of LM group. We conclude that LM is useful in pediatric anesthesia when less circulatory changes are desirable or when the postoperative sore throat or hoarseness is to be avoided.

There is nowadays virtually no contraindication to anaesthesia for even small, sick neonates provided that adequate resuscitation is first carried out. Furthermore, apart from severe trauma and airway difficulties, very few paediatric surgical emergencies require immediate intervention. Most emergencies can be treated within a few hours, preferably when the full facilities of the hospital are available.

We wished to identify patients able to recall intraoperative events after general anaesthesia involving cardiopulmonary bypass (CPB). A balanced anaesthetic technique consisting of benzodiazepines, low dose fentanyl (15.9 +/- 8.5 micrograms.kg-1) and a volatile agent was employed. Perioperative recall was sought utilizing a structured interview on the fourth or fifth postoperative day. ⋯ The incidence of recall in patients undergoing cardiac surgery was less in our group than previously reported. It is, however, higher than the 0.2% incidence recently reported in patients undergoing non-cardiac surgery. This is probably due to patient characteristics and intraoperative factors which make it difficult to avoid periods of relatively light anaesthesia during cardiac surgery.

Review[The role of general or regional anesthesia in the etiology of cognitive disorders in elderly subjects. Literature review].
In the eighties and nineties, eighteen papers were published concerning the influence of general or regional anaesthesia on mental function of elderly patients. In both groups mental changes can be found in the immediate post-operative period, but not on the long term. Analysis of these studies shows a relation between postoperative mental changes and, for example, high doses of drugs, a low preoperative level of mental performance or other factors, associated with personality and environment of the patient.
