background pain management with the use of sedatives and analgesics has several advantages and few complications or side effects. objectives in this study, we planned to evaluate the effects of pain control on oxygen saturation independent of other factors, such previous cardio-pulmonary conditions or respiratory rate. patients and methods sixty-seven adult patients with direct trauma to extrem...

1. Oxycodone hydrochloride (0.1 mg kg-1) was given by intravenous bolus to 18 children after ophthalmic surgery. Plasma was sampled for up to 8 h. Blood pressure, heart rate, peripheral arteriolar oxygen saturation, end-tidal carbon dioxide and halothane concentrations and ventilatory rate were also recorded. 2. Mean (+/- s.d.) values of drug clearance and volume of distribution (Vss) were 15.2...

abstract background: stressors in the intensive care unit (icu) impair patients’ comfort, excite the stress response, and increase oxygen consumption in their body. non‑medical interventions are recommended by several studies as a treatment to improve comfort in the icu patients. sensory stimulation is one of the most important interventions. since arterial blood oxygen saturation is an importa...

These experiments were done to investigate the effects of light and darkness on the oxygenation of the retina in anesthetized cats. Measurements were made with double-barreled oxygen microelectrodes capable of recording both oxygen tension (PO2) and local voltages. Diffuse white illumination presented to a dark-adapted retina led to an increase in PO2 of up to 30 mmHg in the outer half of the r...

Interest in the causes and characteristics of chronic obstructive pulmonary disease (COPD) and its clinical manifestations has grown in the last 10 years. The range of clinical symptoms and other specific characteristics of COPD patients has led it be considered more as a syndrome than a disease, and many investigators have been motivated to define new phenotypes that reflect the particular fea...

background: desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. the aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. methods: this interventional ...
