Comparative StudyComparative studies of artificial respiration sets for babies and infants.
In experiments on appropriately modified manikins the action and effectiveness of artificial respiration sets for infants Penlon (British production) and Ambu (Danish production) were compared. The tidal volume, pressure and characteristics of respiratory phases, rebreathing, oxygen concentration, safety systems and their effect on ventilation were assessed. It was found that better ventilation parameters for the needs of resuscitation of newborns and babies can be obtained using the Ambu set, particularly when compliance is lower and bronchial resistance is higher. The Ambu set is simple, easy and safe to use.

Acid-base balance and blood gases changes and "lactate excess" in acute respiratory alkalosis during general anaesthesia.
In 40 young males aged 18-20 years operated on for inguinal hernioplasty acute respiratory alkalosis was obtained in the 45th minute of general anaesthesia. The values of basic acid-base balance parameters, blood gases, pyruvate and lactate levels and "lactate excess" were determined before and after hyperventilation. ⋯ No changes were observed in the oxygenation of capillary blood and the values of "lactate excess" were normal which rules out tissue hypoxia during acute respiratory alkalosis. Passive hyperventilation being a less dangerous alternative of hypoventilation is a frequent occurrence during general anaesthesia and it causes transient respiratory alkalosis.

Case ReportsAnaphylactic shock following althesin. A case report.
The authors present a case of anaphylactic shock in a 9-year-old girl with heamorrhagic rash developing during anaesthesia. Shock was controlled with steroids, antihistamine drugs and dextran. The authors find it important to consider the possibility of the development of intravascular clotting in anaphylactic shock and the necessity of seeking a history of any allergy in patients before althesin anaesthesia.

Case ReportsKetamine anaesthesia for caesarean section in poor-rick patients.
Caesarean section in a poor-risk patient treated intensively before and after operation is described. The operation was carried out when the patient was in diabetic coma with metabolic acidosis, electrolyte disturbances and low arterial blood pressure. Anaesthesia was conducted using ketamine with nitrous oxide and oxygen. Controlled respiration was performed administering fractionated doses of suxzmethonium.

Comparative StudyComparison of controlled respiration by the manual technique and with a respirator during general anaesthesia for abdominal operations.
These studies investigating the difference between controlled respiration performed by manual technique and controlled respiration applied by means of a respirator during general anaesthesia, and assessing the influence of these methods on the immediate post-operative condition of the patient were carried out on 75 patients during abdominal operations. Gasometric tests in arterial blood were performed before premedication, at intervals of 30 min from the beginning of operation, and 10 min. after the removal of the endotracheal tube. Controlled respiration with a respirator is a more favourable method of pulmonary ventilation during general anaesthesia given for a long-lasting surgical operation. ⋯ The best results were obtained using a respirator with inspiratory volume of 10 ml/kg and respiratory frequency 10/min., which ensured normocapnia. It was observed that oxygenation of arterial blood was reduced postoperatively in all patients but the value of PaO2 was the lowest in patients on manual controlled respiration. Disturbances in acid-base balance and oxygenation had an unfavourable effect and delayed the regaining of consciousness.
