[Trials of propanidid in anesthesia for bronchial endoscopy in infants and children].

This study reports a series of 48 bronchial endoscopies performed in children aged between 3 months and 16 years using Propanidide as sole anaesthetic agent. Individual variations were large. Repeated examinations showed that this type of anaesthetic had only moderate effects upon haemodynamic parameters. Disturbances in pH and PCO2 in arterial blood measured five, fifteen, twenty five and thirty five minutes after induction were less than with anaesthesia by inhalation of halothane. The quality of recovery of such that examinations could be performed on an ambulatory basis. Intravenous administration has the advantage of separating the anaesthetic from the endobronchial examination.

[Neonatal consequences of cesarean section on the presumably healthy infant].

The authors studied the effects on the child of 196 caesarian sections performed in the absence of foetal distress. The following were noted for each child: the time before the first cry, the Apgar score, pH and the need or not for resuscitation techniques. Each feature was studied in terms of different factors: foetal, obstetric, anaesthetic and surgical. The conclusions were as follows: caesarian section, which remains the best means of preventing obstetric trauma, has its own direct complications which are linked to the conditions in which the operation takes place. These can be reduced to a minimum or even completely suppressed if the caesarian section is performed under ideal conditions: few or no depressant drugs before the operation (the use of diazepam for induction should be abandoned); inclined position of 15 degrees, even of the mother has never suffered from utero-caval syndrome and if possible on a heated mattress; extraction of the infant between the 5th and 15th minutes; finally, and above all, prior labour is desirable whenever obstetric conditions permit.

[Reye's syndrome. Report of two cases (author's transl)].

Two cases of Reye's syndrome aged 11 and 13 are reported, confirmed by hepatic biopsy. The favorable outcome observed in the second case seems to be more related with supportive therapy than exsanguinotransfusion and peritoneal dialysis. The physiopathology of this syndrome is not quite clear, but probably in relation with a diffuse mitochondrial insult. Early diagnosis and supportive therapy are important for a favorable outcome.

Cardiac catheterization by percutaneous femoral venous approach in infants weighing less than 5 kg: observations in 97 cases.

The technique of cardiac catheterization after percutaneous introduction of a catheter can now be accomplished in neonates thanks to the refinement of the equipment and to the physicians' experience. In 100 catheterizations performed in infants of less than 5 kg, the new technique was utilized 97 times. Thanks to the utilization of introducers it permits Rashkind atrioseptostomy. Its main advantage is the preservation of venous integrity and this allows repeat investigations through the same route.

Transposition of the great arteries. New technique for anatomical correction.

We describe a new technique for the correction of transposition of the great arteries by "detransposition". An aortopulmonary window is created and a patch placed over this and the coronary ostia so that the coronary arteries arisen from the new aorta. Thus, direct surgery on the coronary arteries is avoided with all the complications which may result from this in neonates and infants. A 4.2 kg infant, with transposition and ventricular septal defect, was successfully operated on using this technique. We discuss the indications for this type of operation and conclude that, until we have more experience, it should be used only in children with a left ventricular pressure at least half systemic.

[Caustic lesions of the esophagus in the child].

On the basis of a study involving 21 children treated over a 10 year period, the authors describe a method for the management of a child following the ingestion of a caustic fluid: emergency oesophagoscopy to determine the extent and nature on the lesions, in severe forms, alimentation gastrostomy, which would seem to be preferable to parenteral alimentation, is carried out, on the 21st day, a new endoscopic and radiological assessment, permitting distinction between those cases which are cured and those progressing to stenosis. In this latter group, the choice is made between dilatations and oesophagoplasty on the basis on the lesions present and the development of complications during dilatation.

[Trial droperidol premedication in infants and children].

Droperidol premedication for children (0.3 to 0.5 mg/kg) was compared with pentobarbital and Dolosal--promethazine). Results are analyzed using criteria proposed by Burken and Nisbet. Droperidol compared very favourably with the order drugs. However a decrease in efficacy was noted with infants and neuw-born children, even with higher doses. The possible incidence it hypertonic seizures renders this drug unsuitable for ambulatory surgery.

[Cholestatic icterus during parenteral feeding in the newborn ano infants].

The authors observed six cases of cholestatis jaundice occuring during parenteral alimentation in the newborn and the infant. In 4 cases, local factors (duodenal atresia, necrosing enteritis of prematurity) or general factors (mucoviscidosis) probably played an essential role. In two cases, the parenteral alimentation seemed to be a main factor, but in one case with excessive and imbalanced supplies of amino acids. Three patients survived, with regression of the jaundice in 15 days to three weeks following the interruption of parenteral alimentation.

[PAH clearance measurement without urine samples in the newborn infant with respiratory distress].

PAH clearance was carried out in 12 newborns, hospitalized in the infantile resuscitation unit for respiratory distress. 6 of these children weighed less than 2.5 kg, 4 had hyaline membrane disease, 6 had either amniotic abnormalities or transitory tachypnea, 2 were surgical patients: one right diaphragmatic hernia, one post-operative respiratory complication after intervention for neonatal occlusion. In 9 cases the newborn was under controled artificial ventilation associated with PEEP at 5 to 7 cm of water. In all of the cases, the hemodynamic, metabolic and blood gas conditions were normal. A control series of 11 newnorn was carried out in a pediatric unit, the clearance was done without urine samples, the rough value of the figures found varied from 5.5 ml per minute to 30 ml per minute in the respiratory distress series and 16 to 62 ml per minute in the control series. The analysis of these results in rendered difficult by the juxtaposition of several factors: Choice of a reference criterion: body surface area, PAH space, patient's weight theoretical weight of the kidneys. The factor of prematurity. The problem of the date of the investigation in comparison with the date of birth.

[Intrathoracic gas effusions of iatrogenic origin in neonatal reanimation].

Intra-thoracic gaseous collections, pneumodiastinum and pneumothorax, have become more common since the use of positive expiratory pressure, either with spontaneous ventilation or in association with artificial ventilation. In our experience, the occurence rate of such collections has increased from 7 p. 100 in 1970 to 19 p. 100 in 1974, related to the use of continuous positive pressure of long duration in the treatment of idiopathic respiratory distress or hyaline membrane disease. These gaseous collections were initially associated with a high mortality (50 p. 100) which is now practically nil. Improved knowledge of the clinical and radiological signs and the insertion of thoracic drains in the presence of the slightest doubt represent the explanation of this reduced mortality.
