چکیده
monary hyperventilation using a closed circuit apparatus designed for this purpose. A highly significant relation was found between oxygen uptake and patient surface area given by the regression equation V2=i6-5 (body weight in kg)213-3.8 ml/min (mean V02= I65 mll minIm2), and between VO2 and body weight given by V°2= 6-74e0076kg+ 4* Values for T02 kg variedfrom Io ml/min per kg to 5 ml/min per kg for a body weight range of 3 to 22 kg. Nitrous oxide uptake decreased with time from induction of anaesthesia given by the highly

The measurement of oxygen uptake in infants with congenital heart disease during general anaesthesia and intermittent positive pressure ventilation.
Oxygen uptake has been measured in congenital heart disease in sedated infants breathing spontaneously via an open circuit (Cayler, Rudolph and Nadas, 1963; Lees, Way and Ross, 1967), and in awake infants by closed circuit (Levison, Delivoria-Papodopoulos and Swyer, 1965). Neither method is suitable during general anaesthesia, the open circuit destroys the characteristics of the T-piece circuit...

متن کاملChanges in heart rate variability during anaesthesia induction using sevoflurane or isoflurane with nitrous oxide.
BACKGROUND The purpose of this study was to compare cardiac sympathetic and parasympathetic balance using heart rate variability (HRV) during induction of anaesthesia between sevoflurane and isoflurane in combination with nitrous oxide. METHODS 40 individuals aged from 30 to 60 years, scheduled for general anaesthesia were equally divided into sevoflurane or isoflurane groups. After 100% oxyg...
متن کاملDifferent Presentation of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery in Adults: Case Reports
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. We report three cases of ALCAPA who survived to adulthood. The first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with ALCAPA using cardiac catheterization and coronary computed tomographic angiography (CTA). The second case was a 30-...
