Background and purpose: Candidates for cataract surgery have high anxiety and worry for various reasons which may cause changes in their hemodynamic parameters. Maintaining hemodynamic stability during anesthesia and surgery is very important. This study aimed at comparing the effects of listening to nature sounds and lavender inhalation on hemodynamic parameters in patients undergoing cataract...

We have compared the effects of inhalation of aerosolized surfactant on experimental acute respiratory distress syndrome. Escherichia coli endotoxin (55 (SD 20) mg kg(-1)) was injected into the tracheas of 36 adult rats anaesthetized and mechanically ventilated with pure oxygen. When the Pa(O(2)) decreased to 11.3 (3.3) kPa, the animals were randomly subjected to inhalation of aerosolized modif...

Respiratory tract injuries caused by inhalation of smoke or chemical products are related to significant morbidity and mortality. While many strategies have been built up to manage cutaneous burn injuries, few logical diagnostic strategies for patients with inhalation injuries exist and almost all treatment is supportive. The goals of initial management are to ensure that the airway allows adeq...

Inhaled nitric oxide (NO), at a concentration of 80 ppm, counters the increase in respiratory resistance (Rrs) induced by methacholine, but fails to prevent a reduction in lung compliance (Crs) in a rabbit model. This study reports the effects of 3, 30 and 300 ppm of inhaled NO. New Zealand White rabbits were intubated and mechanically ventilated with 30% oxygen during neurolept anaesthesia. Me...

Inhalation anesthesia with isoflurane is a well-established and safe method used in small laboratory animals. In most cases oxygen is used as a carrier gas for isoflurane, but room air or mixtures of oxygen with air or nitrous oxide are also being used. Anesthesia is therefore administered using different fractions of inspired oxygen (FiO2), and this may have consequences for the outcome of exp...

OBJECTIVES The present study was carried out to determine whether inhalation of hydrogen (H(2)) gas protects myocardium against ischemia-reperfusion (I/R) injury in swine. DESIGN In anesthetized open-chest swine, myocardial stunning was produced by 12-minute occlusion of left anterior descending coronary artery (LAD) followed by 90-minute reperfusion in the first study. Group A inhaled 100% o...

hypoxemia under certain conditions. However, the relationship between pulmonary anesthetic administration and HPV remains controversial. In conclusion, global effects of inhalation induction with sevoflurane at high concentrations may cause oxygen desaturation in lungs that are normally ventilated with 100% oxygen, potentially resulting in global inhibition of HPV. However, these conditions may...

The ventilatory effects of prolonged oxygen administration were examined in seven dogs during thiopentone anaesthesia. Ventilation, tidal volume (VT), ventilatory rate (f), minute ventilation (VE), inspiratory time (TI), expiratory time (TE), period (Ttot), TI/Ttot and mean inspiratory flow (VT/TI) were measured during the inhalation of room air, after 30 min of oxygen inhalation, and finally a...

Precordial ST-segment mapping was serially applied in the Coronary Care Unit for the study of the effect of oxygen inhalation on the ischemic injury in 17 patients with acute anterior transmural myocardial infarction. A 49-lead ECG system was used. The sum of all ST elevations (ZST) recorded was taken as an index of magnitude of ischemic injury and the number of recording sites showing ST eleva...

The circulatory and metabolic effects of inhalation of oxygen in high concentration were investigated in 50 patients with acute myocardial infarction. The heart rate, arterial blood pressure, cardiac out-put, blood gas tensions, pH, and lactate and pyruvate levels were measured. In general, oxygen inhalation produced a fall in cardiac output and stroke volume and a rise in blood pressure and sy...
