Comparative Study
The auditory steady state response during sufentanil anaesthesia.
The auditory steady state response (ASSR) is a sinusoidal evoked potential elicited by rapidly repeated auditory stimuli. The ASSR was recorded in eight patients during high-dose sufentanil anaesthesia for cardiac surgery in order to assess its usefulness as a measure of the level of consciousness. The electroencephalogram (EEG) was recorded for comparison. ⋯ The amplitude increased with early signs of awakening in the Intensive Care Unit. With few exceptions, changes in the simultaneously recorded EEG were similar to those of the ASSR. The ASSR deserves further evaluation as a tool for monitoring level of consciousness during high-dose opioid anaesthesia.

One thousand patients who were anaesthetised between February and April 1990 at University Hospital, Nottingham were interviewed between 20 and 36 hours after their operation. Patients under 16 years of age, those who had undergone obstetric or intracranial surgery, those who were unable to communicate and patients who were discharged from hospital before the postoperative visit were not interviewed. A standard set of questions was used to determine the incidences of recall of events and dreams during the operation. These incidences were 0.2% and 0.9% respectively, considerably lower than reported in previous comparable studies.

Comparative Study
[Regional or general anesthesia in patients with pulmonary risks?].
Such partial functions of the respiratory system as ventilation, gas exchange, bronchomotor tone, respiratory regulation, secretion within the airways, mucociliary clearance, etc., are less impaired by such procedures as peridural or spinal anaesthesia than by general anaesthesia. As a result, it is often concluded that regional anaesthesia should always be used preferentially in the case of patients with a pulmonary risk. ⋯ These are factors that cannot readily be influenced by anaesthesiological measures. For this reason, the pre-operative diagnostic evaluation and preparation, post-operative prophylaxis and treatment, including the components pain elimination, physiotherapy, respiratory therapy, broncholysis and secretolysis, are more important than the anaesthetic procedure itself.

Comparative Study[Relation between foci of chronic oral infection, rheumatic fever and general or local anesthesia].
We make a study about Rheumatic fever diagnostical on boys who need an exeresis of bucals focus, which we make under general or local anaesthesia effects, and we verify the quantity of ASLO descent which depended on type of anaesthesia and the number of sessi that we make.

Randomized Controlled Trial Comparative Study Clinical TrialPrevention of deep vein thrombosis after total hip replacement. The effect of low-molecular-weight heparin with spinal and general anaesthesia.
Enoxaparin, a low-molecular-weight heparin, has been used together with spinal or general anaesthesia in a prospective, randomised study of 188 consecutive elective hip replacements. Bilateral venography was performed on all patients on day 13 after operation. Group I (65 patients) received spinal anaesthesia and no immediate injection of enoxaparin. ⋯ Tolerance was good and the incidence of bleeding low in the three groups. Our results confirm the low rate of DVT in patients operated on under general anaesthesia with the standard procedure of 40 mg of enoxaparin on a once-daily basis started pre-operatively. The 40 mg-dose is also safe and effective in association with spinal anaesthesia if half the dose (20 mg) is injected an hour after the lumbar puncture.
