[Anesthesiological provision of patients with tachyarrhythmias during radio-frequency ablations].

The paper presents the results of anesthesia in 55 patients aged 18 to 70 years during radio-frequency ablation for different types of tachycardias.

[Reaction of the sympathoadrenal system in young children with congenital heart defects during cardiopulmonary bypass surgery]. / Reaktsiia simpatoadrenalovoi sistemy u detei rannego vozrasta s vrozhdennymi porokami serdtsa, operirovannykh v usloviiakh iskusstvennogo krovoobrashcheniia.

Reactions of the sympathoadrenal system were studied during surgical interventions in children aged 1.5-3 years with congenital heart disease operated under conditions of artificial circulation and hypothermia. The state of the sympathoadrenal system was different in uneventful and complicated course of the operation, which may indicate a different efficiency of the neurovegetative blocking and antistress protection from surgical trauma.

[Initial experience in the correction of the tetralogy of Fallot in infants using an approach through the right atrium and the pulmonary artery]. / Pervyi opyt korrektsii tetrady Fallo u detei rannego vozrasta dostupom cherez pravoe predserdtsie i legochnuiu arteriiu.

Radical correction of Fallot's tetralogy by means of an approach through the right atrium and pulmonary artery without ventriculotomy (10 patients) or with minimal ventriculotomy (23 patients) was carried out in children whose ages ranged from 13 to 50 months and body weight from 7.9 to 15 kg. Lethality was 12%. The death of 3 patients was not connected with the peculiarities of the surgical tactics, the death of the fourth patient was due to insufficient experience in development of the surgical techniques of the first operations. The operative techniques applied are described in detail and the possibility of adequate correction of Fallot's tetralogy by it is proved principally. The late-term operative results are good in 10 patients. The first results of the suggested method of surgical correction of the anomaly are claimed by the authors to be promising, which allows them to continue its further elaboration.

[Acid-base state and the electrolyte balance of young infants in the immediate postoperative period after radical correction of an interventricular septal defect under artificial circulation]. / Kislotno-shchelochnoe sostoianie i élektrolitnyi balans u detei rannego vozrasta posle radikal'noi korrektsii defekta mezhzheludochkovoi peregorodki v usloviiakh iskusstvennogo krovoobrashcheniia v blizhaishem posleoperatsionnom periode.

Acid-base equilibrium and electrolyte balance were studied in 80 infants in the immediate postoperative period after surgery for ventricular septal defect under conditions of extracorporeal circulation. Decompensated metabolic alkalosis was the most characteristic disorder of acid-base equillibrium in patients with an uncomplicated postoperative period, whereas decompensated respiratory alkalosis and metabolic acidosis were characteristic of patients with compensated and decompensated forms of cardiac insufficiency. Plasma hypokaliemia and hypochloremia attended by intracellular retention of sodium were typical disorders of the electrolyte balance in all forms of changes in the acid-base equilibrium.
