SUMMARY A method for the predetermination of die safe lengdi of nasotracheal tubes in infants and children is presented. The distance from die nostril to die carina was found to correlate better widi the height than widi die body weight, surface area or age of the patient. The investigation was made by measuring die inserted lengdis of die tubes at extubation and die distance between die tube tip and the carina in radiographs in 200 infants and children. In die statistical analysis, die equation for die regression line was: nostril‐carina distance (cm) = 0.16 × height (cm) + 4.5 (cm), die standard error s̄=± 1.2 cm and die correlation coefficient 0.96 (R2). The importance of predetermination of die tube lengtii in prolonged intubation is emphasized. ZUSAMMENFASSUNG Es wird eine Mediode zur Vorausbestimmung einer Sicherheitslänge nasotrachealer Tuben für Sauglinge und Kinder vorgestellt. Die Korrelation des Abstandes zwischen Nasenloch und Carina war zur Körpergrösse besser als zum Körpergewicht, zur Körperoberfläche oder zum Alter des Patienten. Für diese Untersuchung wurde bei 200 Säuglingen und Kindern der Abstand zwischen Tubusende und Carina im Röntgenbild sowie die Länge des eingeführten Tubusanteiles anlässlich der Extubation gemessen. Für die Regressionslinien wurde in der statistischen Anlyse die nachstehende Gleichung verwendet: Nasenloch‐Carina‐Abstand (in cm) = 0,16 × Körpergrösse (in cm) + 4,5 (cm). Die Standardabweichung s̄ war ± 1,2 cm, der Korrelations‐Koeffizient 0,96 (R2). Auf die Bedeutung der Vorausbestimmung der richtigen Tubuslange für die Langzeitintubation wird nachdrucklich hingewiesen.

causcs practically no discomfort. The "hyalase" helps to rctlucc the resistance of the tissues to the injection of contrast medium, and the spread and absorption of the medium, and consequently the excretion is also thus considerably accelerated. Using this technique, excellent urograms, fully comparable with those obtained with the intravenous method, were made.The method has been tried out in clinical practice during the past year and has proved to be a valuable aid in the examination of kidneys and urinary passages, particularly in infants and young chi Idren.

The study is based on 45 children with chronic bronchitis. Their ages varied between 2 and 15 years, the average being 8 years 6 months. 44 children had diseases of the nose, paranasal sinuses or nasopharynx. Adenotomy was performed on 42 children and 16 of these were helped by this operatioa. In 22 cases intranasal antrostomy was made in the inferior meatus with a good or satisfactory result in 14. The Caldwell-Luc operation, performed on 14 children, had a good or satisfactory effect on both sinusitis and bronchitis in all cases thus treated. 26-722957
