Randomized Controlled Trial Comparative Study Clinical Trial[Clinical and neuropsychologic evaluation of different anesthesia techniques (propofol vs isoflurane) in general surgery].
Different anaesthetic techniques in the perioperative period (induction and maintenance of anesthesia, recovery and 48 postoperative hours) were evaluated in 200 patients undergoing general surgery. After randomization, results from 4 groups, were clinically and statistically compared according to the anesthetic techniques performed (propofol + fentanyl in air/O2; isoflurane + fentanyl in air/O2; propofol + fentanyl in N2O/O2; isoflurane in N2O/O2). The results show that anesthesia without N2O is difficult and fentanyl isn't the ideal analgesic; but no difference was found between the anesthetic techniques in quality of induction and maintenance, speed of recovery and quality of postoperative period.

Case ReportsDouble simultaneous hemodialysis during prolonged cardio-pulmonary resuscitation for hyperkalemic cardiac arrest. Case report.
A 57-year old male uremic patient developed a sudden cardiac arrest due to severe hyperkalemia. The cardiac arrest lasted 135 minutes and was initially unresponsive to conventional therapy. It was successfully treated by prolonged external cardiac massage, assisted ventilation and double simultaneous arteriovenous hemodialysis to rapidly decrease the high potassium level.

[Monitoring of cuff pressure in double-lumen endotracheal tubes during anesthesia for thoracic surgery].
It is well known that cuff overinflation in endotracheal tubes may cause serious damage to the tracheal mucosa. Cuff overinflation is also related to the diffusion of nitrous oxide across the cuff membrane, thus giving way to a progressive volume/pressure increase up to overcoming, critical capillaric perfusion pressure. The kinetics of hi-lo cuff-pressure in single-lumen endotracheal tubes during general anesthesia using nitrous oxide has been well documented. ⋯ In ten of these case, special equipment was used in order to keep the cuff-pressures steady and at the lowest sealing level. The pressure shows the same trend in both cuffs but, depending on the medium calibre of the main left bronchus and the volume/pressure relations of the endobronchial cuffs, the pressure in the latter increases faster. The investigation was performed using an original equipment developed by the authors; such equipment is able not only to monitor the cuff-pressures, but also to maintain them at steady controlled levels (below 20 cm water seal), by means of counterregulating all the volume variations due either to anesthetic requirements, or to the diffusion of nitrous oxide.(ABSTRACT TRUNCATED AT 250 WORDS)

[Automatic fluid control during high-flow continuous hemofiltration: the Equaline system].
To describe the use of an automatic fluid control system, Equaline, during high flux continuous hemofiltration. ⋯ Equaline system was able to maintain intravascular volume in the face of high ultrafiltration rate avoiding clinically important discrepancies between ultrafiltrate formation and fluid replacement. We conclude that PDCVVH management is greatly improved with use of such servo-controlled feedback system.

[Peridural administration of low-dose morphine on demand following major abdominal surgery].
The present report deals with 20 patients undergoing major abdominal surgery, in whom a postoperative antalgic regimen has been administered on demand by means of morphine via lumbar peridural catheter. We injected 3 mg as the first dose after surgery and subsequent 2 mg doses when required. In each patient we controlled regularly for 72 hours the following: respiratory function, antalgic effects and side effects. We concluded that this technique is fit to obtain good analgesia with rare and mild side-effects.
