[Management of pediatric airway--anatomy, physiology and new developments in clinical practice].

Due to the special features of paediatric anatomy and physiology, the expected and unexpected difficult paediatric airway is one of the major challenges to every anaesthesiologist, paediatrician and emergency physician. During the last years, some new devices have been made available to improve airway management in children and infants, and several studies have advanced our understanding of the risks and benefits of our clinical practice. Certain risk factors for airway related problems during anaesthesia in children having a "cold" have been identified, and there are new aspects of the controversy concerning the use of cuffed endotracheal tube (ETT) in children. New video assisted systems have been introduced for the management of the difficult airway in paediatric patients, and new applications for well-known devices have been suggested, e.g. the laryngeal mask airway (LMA) serving as guidance for fibreoptic intubation. Recent studies have also demonstrated specific problems with the LMA in infants, as well as possible advantages of a new prototype LMA for children, similar to the ProSeal. Furthermore, the following review presents data about the use of the Cuffed Oropharyngeal Airway (COPA) and the Laryngeal Tube (LT) in paediatric patients.

Congenital defects of respiratory system among the children hospitalized in the clinic in years 1983-1989.

Congenital defects of respiratory system in children constitute a small percentage of all innate defects. In 1983-1989 in the Clinic Pulmonology and Allergology Medical School in Warsaw hospitalized 2522 children. Authors recognized the congenital defects of respiratory system in 29 cases. The opinions of authors only a complex diagnostic examinations makes it possible in most of the cases to rapidly correct diagnosis and choose proper treatment.

[Bronchoscopy and bronchography in newborn infants and infants].

In 20 years (1965 to 1984) 428 infants (604 investigations) in the first year of life were bronchoscoped in our hospital; 109 out of them were newborns (119 investigations). Bronchographies were performed in 94 infants including 2 newborns. In the last 10 years the number of investigations decreased. Most frequent indications of bronchoscopies were stridor, aspiration and atelectasis. The usefulness of bronchological investigations in patients with oesophago-tracheal fistula, tracheal stenosis following long time intubation and bronchopulmonary dysplasia is pointed out. The diagnostic bronchoalveolar lavage can be recommended for newborns and infants too.

Measurements of tracheobronchial clearance in patients with immotile-cilia syndrome and its value in differential diagnosis.

Tracheobronchial clearance was studied in twenty patients who fulfilled suggested criteria of the immotile-cilia syndrome and in eight other patients suspected of suffering from the syndrome, but who did not fulfill the criteria. Clearance was studied using 6 micrometers teflon aerosol particles tagged with 99mTc and external measurement of the radioactivity. The criteria were based on combinations of a typical history of bronchitis, rhinitis and sinusitis since childhood, hereditary data, situs inversus, sperm immotility and characteristic defects of respiratory tract cilia and sperm tails. All patients who fulfilled the criteria had an extremely slow, probably no, tracheobronchial mucociliary clearance, whereas all those who did not fulfill the criteria had some clearance. Evidently the diagnosis immotile-cilia syndrome can be obtained without clearance measurements in typical cases, but such measurements are of value in atypical cases, especially for excluding the syndrome.
