Case Reports[Anesthesiologic problems in patients with Launois-Bensaude-Madelung disease. Clinical case].
Authors report a Launoise-Bensaude-Madelung disease case, in a 64 year old man, admitted to a Plastic Surgical Department for obesity, dysphonia, dysphagia, dyspnea. Early symptoms appeared 20 years before Hospital admission. Lipomatous tissue occupied nape, mandible, neck and shoulders. ⋯ Tracheal stenosis required many attempts for correct nose-tracheal intubation. Fiberoptic instrument as guide for tracheal tube can be useful for patients with Launoise-Bensaude-Madelung disease, when tracheal intubation is considered difficult or impossible. Knowledge of fiberoptic tracheal intubation techniques is mandatory for anesthesiologists, allowing tracheal intubation in patients with anatomical variations of mouth or upper respiratory airways.

Randomized Controlled Trial Clinical TrialInteractions between mivacurium, rocuronium, and vecuronium during general anesthesia.
This study was designed to examine the interactions between mivacurium and rocuronium or vecuronium when administered during a standardized anesthetic technique. Seventy healthy women undergoing abdominal hysterectomy procedures with a standardized thiopental-sufentanil-desflurane-nitrous oxide anesthetic technique were randomly assigned to one of seven treatment groups (10 patients each). After a tracheal intubating dose of vecuronium 100 micrograms/kg (Groups 1 and 2), rocuronium 600 micrograms/kg (Groups 3 and 4), or mivacurium 250 micrograms/kg (Groups 5, 6, and 7), patients received vecuronium, 25 micrograms/kg (Groups 1 and 6), rocuronium 150 micrograms/kg (Groups 3 and 7), or mivacurium 50 micrograms/kg (Groups 2, 4, and 5) for maintenance of neuromuscular blockade. ⋯ The clinical duration of maintenance doses of vecuronium (18 +/- 6 min) and rocuronium (13 +/- 2 min) were significantly shorter after an intubating dose of mivacurium than that after an intubating dose of vecuronium (30 +/- 5 min) or rocuronium (42 +/- 12 min), respectively. These data suggest that with consecutive administration of neuromuscular blocking drugs, the initial duration of action depends more on the kinetics of the first neuromuscular blocking drug than the subsequent drug. Thus, there appears to be no clinical advantage in using mivacurium for maintenance of neuromuscular blockade after initial administration of rocuronium or vecuronium.

Randomized Controlled Trial Clinical TrialRandomized trial of epidural versus general anesthesia: outcomes after primary total knee replacement.
To compare the effects of epidural anesthesia and general anesthesia on early postoperative outcomes after unilateral primary total knee replacement, 262 patients were randomly assigned to receive either epidural or general anesthesia. All patients received a common rehabilitation protocol including a standardized assessment of progress. One hundred eighty-eight patients received a common thromboembolic prophylaxis protocol with postoperative aspirin, and had a standardized surveillance protocol to detect thromboembolic complications. ⋯ Epidural anesthesia is associated with more rapid achievement of postoperative in hospital rehabilitation goals after total knee replacement. A minor reduction in postoperative deep vein thrombosis rate was observed with epidural anesthesia, but this did not reach statistical significance. No difference in early postoperative pulmonary embolism was observed between the 2 types of anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Simulated difficult intubation. Comparison of the gum elastic bougie and the stylet.
A randomised study was carried out to compare the efficacy of the gum elastic bougie and the stylet in a simulated difficult intubation. A laryngoscopic assessment, as described by Cormack and Lehane, was made in 100 patients. A Grade 3 view was then simulated. ⋯ In the Stylet First Group (50 patients) the order was reversed. After two attempts the tube was correctly placed in the trachea in 96% of cases in the Bougie First Group compared to only 66% of cases in the Stylet First Group (p < 0.001). We recommend that a gum elastic bougie should be readily available and that anaesthetists should use it in preference to a stylet whenever a good view of the glottis is not immediately available.

[Effect of oxygen therapy on the postoperative patient under general anesthesia].
Adequate oxygen administration has shown a definite benefit for preventing postoperative patients from hypoxia after weaning. Nosal cannula of 3L/min flow rate may maintain a satisfactory blood gas result. For its easy and effective. It should be recommended as a routine intervention of postoperative oxygen therapy especially for those patient whose respiratory function were normal before surgery.
