[Continuous positive pressure respiration by nasal route (n-CPAP) as a preferred treatment method in various types of acute respiratory insufficiency in newborn infants].

The process of adaptation for extrauterine life can be easily disturbed by respiratory insufficiency. The surfactant deficiency as well as anatomical and physiological immaturity of a newborn can be considered as etiological factors in some diseases, such as respiratory distress syndrome (RDS), transient tachypnoea (TT) syndrome, segmental atelectasis or pneumonia complicated by atelectasis. The widespread used method of treatment is based on mechanical increase of difference between alveolar and atmospheric pressure. So-called constant distending pressure (CDP) increases functional residual capacity (FRC), keeps alveoli open and finally increases oxygenation of arterial blood. During 3 years period continuous positive airway pressure by nasal route (n-CPAP) was used as only one method in 26 newborns. The newborns were treated because of RDS (15 cases) and pneumonia with atelectasis (11 cases). n-CPAP was starting with pressure 8 cm H2O (0.8 kPa) and FIO2 0.5, if atelectasis with severe dyspnea, hypoxia and forced hyperventilation were found. This method was very well tolerated. 22 newborns treated for 2-7 days--survived, 4 small-for-date babies--died. The most common cause of death was septicaemia complicated by disseminated intravascular coagulation. The moderate hyperbilirubinemia, oliguria with tissue oedema was observed in many cases. The light nostril decubitus were only complications. No pneumothorax was detected. We found n-CPAP as a simple, safe method in treatment of atelectasis in newborns.

[General anesthesia in infants].

It is generally accepted, that the progress in surgical treatment of congenital malformation is closely related to the progress in highly-specialised methods of newborn anaesthesia. The safe methods of anaesthesia have to be adapted to anatomical and physiological peculiarities of the earliest days of life as well as to different reaction to drugs and anaesthetics. The preoperative preparation in newborns used to be often very short, because most of the problems of the neonatal period are emergency surgical interventions and there is no time for treatment even of the serious disturbances of basic physiological functions. The purpose of this study was to estimate methods of general anaesthesia in newborns, which have been introduced in the Anaesthesiology Department of the National Research Institute of Mother and Child. The main element of these methods was general anaesthesia with muscle relaxants and controlled ventilation as a routine. The estimation was based on general analysis of 10 years practice when these methods of anaesthesia were used. During this time 515 anaesthesias to 408 both-sex newborns were given (Tab. I, Fig. 1). 85% of anaesthetized newborns were operated because of congenital malformations (Tab. I); 46% of operations were performed during their first week of life, 21% were operated in first 24 hours of life, mostly as an emergency (Fig. 3). 10% of operations were performed is prematures (body weight below 2500 g) (Fig. 4). The "routine" anaesthesia was given in 82% cases. Awake intubation in unpremedicated newborns was performed. Anaesthesia was maintained with nitrous oxide-oxygen mixture (1:1 or 2:1). D-tubocurarine in 95% of cases was used. The initial dose 0,5 with matures and 0,25 mg with premature babies was used. If necessary supplementary doses were given. During anaesthesia, intermittent positive pressure ventilation (IPPV) with frequency at least 60/min. was used. During this ventilation, hyperventilation and positive end-expiratory pressure (PEEP) were obtained. Precordial stetoscope and thermometer probe was used as a routine. In some special cases eCG, end-expired CO2 (capnography), pletysmography were also recorded; blood gas analyses were checked. All intra- and postoperative complications as well as postoperative mortality have been analysed in details. During 3,3% of operations some complications had been observed. The total incidence of early psotoeprative complications was 20%. In this group the most frequent were respiratory complications (16,1%). Serious disturbances in pulmonary gas exchange during operation and early postoperative period were not found.(ABSTRACT TRUNCATED AT 400 WORDS)
