RESUMEN

The measurement of transcutaneous PtcO2 in eight normal adults prove a comparable efficacy of 50 l.min-1 O2 through facial "small mask" (61.5 kPa; 463 mmHg) and 20 l.min-1 O2 through head tent (65.1 kPa; 490 mmHg). First procedure, inexpensive, is very simple to use.

RESUMEN

When tracheal intubation is conducted with traditional laryngoscope PtcO2 fall during the first minute after intubation; when continuous O2 supplied laryngoscope (Laryng O2) is used PtcO2 rise; the difference is statistically significant (p less than 0.001) either the subjects are in curarisation apnea or in spontaneous ventilation. With traditional laryngoscope, the fall is faster with spontaneous ventilation conditions than during curarisation apnea. Likewise in normal conscient subject the same fall is faster (p less than 0.001) during first minute of posthyperoxic spontaneous quiet ventilation than the first minute of voluntary hypocapnic apnea induced by hyperventilation during the same hyperoxia. Such results have to be taken into account for the indications of tracheal intubation technical means if hypoxic conditions are to be suspected, particularly for infants and subjects with cardio-respiratory failure.

RESUMEN

To suppress the risk inherent in laryngeal microsurgery performed with a CO2 laser beam, the authors suggest to use a reinforced silicone endotracheal tube, the cuff of which is protected by a silicone plus aluminium powder shield. The resistance of silicone to fire is augmented during laser shots by a nitrogen flow on the upper side of the shield at the rates of 2 l/min in patients breathing air and 30 l/min in patients give oxygen.

RESUMEN

The authors relate their experience of 61 inhalation anesthesia of children from 5 months to 15 years years old. Head-tent is usually employed for intensive care as a method to administrate pure oxygen. Children are often afraid of the face-mask and tolerate head-tent easier. Three different protocols were studied: Nitrous oxide and oxygen mixture at different level (50 p. cent oxygen, 50 p. cent nitrous-oxide; or 30 p. cent oxygen, 70 p. cent nitrous oxide). The authors also used halothan in the inhalated mixture. The rebreathing level of CO2 in the head-tent according to the gas flow was measured. No incident, nor accident are related. This new anesthetic apparatus is easy to use, well accepted by children.

RESUMEN

Using a spectrometer for the study of exhaled gases and a monitor of transcutaneous oxygen pressure, our purpose has been to quantify our ideas about physiological apneas in the conscious voluntary adults. We compared the apneas, concerning the duration and the induced fall of peripheric oxygen pressure, after normoventilations in air and in oxygen, then after hyperventilations in air and in oxygen. These experiences confirm the tiny interest of previous normoventilation in oxygen compared with in air, the danger of hypoxemia by previous hyperventilation in air and the possibility of prolonged but safe apnea after hyperventilations in oxygen, that we can advocate in the induction of anaesthesia for some circumstances.

RESUMEN

The authors relate their experience of 61 rectal anesthesias with ketamine (10 mg/kg) and diazepam (0.25-0.5 mg/kg). Rectal anesthesia is well accepted by children who are afraid of percutaneous injection. When ketamine is used alone, they obtained only 76 p. cent good result. When diazepam is associated, good results arise to 95 p. cent. Diazepam added to ketamine allows surface surgery during 10 to 15 minutes.
