Comparative Study[Changes in intraocular pressure during anesthesia with intratracheal intubation or laryngeal mask].
To compare the effects of the laryngeal mask airway (LMA), and the tracheal tube (TT) insertion on intra-ocular pressure (IOP) in eye surgery. ⋯ LMA insertion does not elicit significant haemodynamic or IOP changes. Conversely, the TT increases HR, MAP and IOP. These changes can be deleterious in case of emergency surgery for perforating eye injuries. The LMA can be recommended as an alternative to TT in eye surgery, provided security rules are followed, because of the risk of displacement of LMA during surgery.

[Blood loss from diagnostic laboratory tests performed in intensive care units. Preliminary study].
To assess the volume of blood samples withdrawn for laboratory testing in intensive care unit (ICU) patients and to determine the influence of the resulting blood loss on transfusion requirements in patients staying in the ICU for more than seven days. ⋯ Blood losses from blood withdrawal for laboratory tests are important and in agreement with the results of other reports. It is generally accepted that iatrogenic blood loss of this magnitude can cause anaemia if repeated over a prolonged period. Conversely, our data suggest that blood sampling does not contribute significantly to anaemia and transfusion requirements in patients with a prolonged ICU stay.

Comparative Study[Delay of clinical recovery from paralysis induced by atracurium: comparison between orbicularis oculi and adductor pollicis].
To compare with train-of-four stimulation the delays of the beginning of the spontaneous recovery of the orbicularis oculi and of the adductor pollicis after profound neuromuscular blockade with atracurium. ⋯ The orbicularis oculi should not be monitored alone for assessment of recovery from profound neuromuscular blockade by atracurium, as it predicts poorly the time of the recovery of the adductor pollicis.

Comparative Study[Evaluation of cognitive functions after anesthesia with propofol].
To assess the disturbances and delay of recovery of cognitive functions following propofol anaesthesia, and to evaluate a series of simple cognitive recovery tests. ⋯ Complete recovery can be evaluated by simple cognitive tests, which showed that cognitive functions are impaired over a longer period than psychomotor functions. Oral instructions may therefore not be fully understood by the patient within 3 hours after anaesthesia, emphasizing the importance of written instructions and the essential role played by a well-informed accompanying person.

[Inspiratory aid with facial masks during acute respiratory failure without hypercapnia].
This prospective study assessed, in 10 conscious patients without a history of chronic respiratory disease, the feasibility of mechanical pressure support ventilation with PEEP by face mask for the treatment of acute respiratory failure without hypercapnia. Pressure support level was determined to obtain a VT of 5 to 10 mL.kg-1 and a decrease of respiratory rate of more than 20%. FIO2 and PEEP levels were determined to obtain a SpO2 > 92% and a PaO2 > 70 mmHg. ⋯ The technique was efficient in all patients and tracheal intubation was not required. During face mask ventilation, a significant decrease in respiratory rate and an increase in PaO2 and SaO2 were observed. Pressure support ventilation with PEEP by face mask is an efficient technique for the treatment of acute non hypercapnic respiratory failure in conscious and cooperative patients.
