[Comparison of a combination of fentanyl and alfentanil with propofol in brief surgery].

We studied 96 patients undergoing short gynecological procedures. Anaesthesia has been induced with fentanyl 1.5 micrograms/kg (45 patients) or alfentanil micrograms /kg (51 patients) and a hypnotic dose of propofol, and maintained with 70% N2O via facial mask. We observed a better and more rapid control of surgical analgesia with alfentanil, and an earlier recovery of postoperative psychophysical functions. Post-induction apnea has been more frequent and prolonged in the alfentanil group, but no difference in the time necessary to recover an adequate ventilation has been observed between the two groups. Alfentanil anaesthesia determined a more marked intraoperative bradycardia. By virtue of the speed of onset and the short duration of action, alfentanil is a suitable anaesthetic agent for short surgical procedures, particularly in day-stay patients.

[Muscular rigidity caused by alfentanil: prevention].

We studied three groups of 30 patients each, undergoing minor orthopaedic surgery, anaesthetized with alfentanil (30 micrograms/kg bolus followed by an infusion of 0.3 micrograms/kg/min), thiopental 3 mg/kg and 70% N2O via facial mask. Patients in group I were treated, three minutes before induction, with vecuronium 0.02 mg/kg i.v., while those in group II were premedicated with diazepam 0.15 mg/kg i.m. 30-45 minutes before induction. Group III served as control. Muscular rigidity was evaluated clinically with a subjective score based on a scale of 0 (no rigidity) to 3 (severe rigidity). Diazepam did not give significant protection from muscular rigidity. Vecuronium administration did not significantly reduced the number of patients who became rigid, but significantly decreased the incidence of severe rigidity (p less than 0.005), the mean rigidity score (p less than 0.05) and the incidence of rigidity at the induction of anaesthesia (p less than 0.0005). We also observed a progressively increasing incidence of rigidity with increasing age (not significantly) and body weight (p less than 0.05 total rigidity, p less than 0.01 severe rigidity).

[Anesthesia for shoulder surgery. Comparison of anesthesiologic problems and technics].

We evaluated the ability of general, regional (interscalene block) and balanced anaesthesia (interscalene block supplemented by general anaesthesia) to manage the problems of shoulder surgery. Our results show that general anaesthesia is not adequate. Interscalene block provides intra and postoperative analgesia, allows an early realization of the postoperative rehabilitation programme and quickens the recovery of shoulder function. Therefore, interscalene block should routinely be performed. The positions of patient and surgeons cause the main disadvantages of anaesthesia with interscalene block alone, ad the control of airway of sedated patients is difficult and performing general anaesthesia in case of insufficient analgesia may be troublesome. Balanced anaesthesia, as compared to regional block alone, allows a safer control of respiration and an easier control of surgical analgesia.
