Comparative Study[Use of nitrous oxide as a component of general anesthesia monitored by pulse oximetry during one-lung ventilation].
Pulse oximetry was employed to monitor the arterial blood oxygenation during surgery of 300 patients with pulmonary carcinomas. N2O2 anesthesia in 2:1 ratio was administered to all the patients. Change for one-lung ventilation did not lead to changes of SpO2 in 59% of the patients, whereas in 41% of the patients this value reduced below 93%. Change of the gas ratio to 1:1 in 35% of the cases was found sufficient to elevate the SpO2 value to the norm and only in 6% of the patients N2O2 had to be excluded from the anesthesia scheme for the period of one-lung ventilation and artificial ventilation with pure oxygen had to be resorted to.

Comparative Study[Complications and peculiarities of anesthesia in abdominal delivery].
Analysis of the reasons responsible for complications of anesthesia in abdominal delivery has shown that such complications are most frequent before fetus extraction. They are: poorly corrected hypo- or hypertension and tachycardia; damages of major vessels, pleura and lungs upon central vein puncture; severe hypoxia in difficult or abortive intubations with mouth, larynx, pharynx, trachea and esophagus injuries; regurgitation and development of aspiration pneumonia (Mendelson syndrome); toxic and allergic reactions to psychopharmacological, narcotic and local anesthetic agents; signs of laryngobronchiolospasm; complications during suture of the uterus and abdominal cavity when main anesthesia is performed (hypotonic bleeding with the onset of ARDS, hemodynamic disturbances due to microembolism of the pulmonary artery branches upon active contractions of the uterus caused by uterotonics, side effects of myorelaxants); complications in the early postoperative period (prolonged apnea, the onset of acute cardiopulmonary and hepatic failure).

[The effect of a nitroglycerin infusion on the hemodynamics, extravascular lung water and gas exchange in patients with adult respiratory distress syndrome].
Nine patients with adult respiratory distress syndrome, stage III, secondary to diffuse peritonitis have been examined. The patients were subject to pulmonary artery and aorta catheterization. ⋯ Selective hypotension in the pulmonary circulation was performed using an infusion of nitroglycerin solution. Despite differences in the response of patients with ARDS to nitroglycerin, when the drug was injected with optimal positive end-expiratory pressure, it promoted an increase in O2 delivery, normalization of pulmonary hemodynamics and a decrease in extravascular pulmonary water.

[The hemodynamic effects of ketamine anesthesia in children with congenital heart diseases].
One hundred and thirty five children have been examined after surgery for congenital heart valve defects performed under ketamine anesthesia. It has been established that ketamine anesthesia has no considerable effect on the preload and cardiac pump function. ⋯ A spasm in the vessels of the conjunctiva is observed even when small drug doses are used. This may be accounted for by calcium accumulation in the muscular cells, noradrenaline hyperproduction, enhanced sensitivity of sympathomimetic receptors to circulating endogenous catecholamines.

Comparative Study[The importance of the monitoring of free-radical processes in the diagnosis and treatment of septic shock in newborn infants].
The changes in free-radical processes have been studied using peroxide chemiluminescence of the blood sera in patients with meconial-aspiration syndrome on controlled lung ventilation and in the newborns with severe forms of sepsis. Monitoring of free-radical processes may be used for the diagnosis and prediction of septic shock and hemosorption prescription.
