Hyperbaric oxygen therapy (HBOT) has been proved as an important tool in healing of CO poisoning, necrosis, ischemic wounds, inflammatory diseases or brain injuries. Reactive oxygen species (ROS) play a key role in healing potential of HBOT however potential side effects must be taken into account. Equally important is also duration of HBOT. We can conclude, that despite several decades of HBOT...

Inhaled nitric oxide (NO) is occasionally used to treat hypoxemia for patients with acute respiratory distress syndrome (ARDS) in the intensive care unit (ICU). However, it is controversial whether or not to maintain inhalation of NO during general anesthesia because of complications, such as nitrogen dioxide (NO(2)) production, methemoglobinemia, and inhibition of platelet aggregation. In this...

Context Periodontal surgical procedures produce varying degree of stress in all patients. Nitrous oxide-oxygen inhalation sedation is very effective for adult patients with mild-to-moderate anxiety due to dental procedures and needle phobia. Aim The present study was designed to perform periodontal surgical procedures under nitrous oxide-oxygen inhalation sedation and assess whether this tech...

BACKGROUND AND PURPOSE Tracer studies have demonstrated that 100% oxygen inhalation causes a small cerebral blood flow (CBF) decrease. This study was performed to determine whether arterial spin-labeling (ASL), a noninvasive MR imaging technique, could image these changes with clinically reasonable imaging durations. MATERIALS AND METHODS Continuous ASL imaging was performed in 7 healthy subj...

In mothers nursed in a semi-recumbent position, arterial oxygen tension was measured at the beginning and END OF AN an intermittent period of inhalation, Lasting for six contractions, during the first stage of labour. Ten mothers had methoxyflurane 0.35 per cent and air, followed by methoxyflurane 0.35 per cent with approximately 50 per cent oxygen. Another 10 mothers had 50 per cent nitrous ox...

although delivering of oxygen to patients seems to be easy, but this procedure can include some risks. in this article, we try to show you how this procedure can perform in a safe manner.   have you ever worked in a medical-surgical ward, or emergency department, or also in intensive care unit?   perhaps you ever have the care of patients who have need for supplemental oxygen. oxygen therapy is...

The effect of oxygen inhalation at atmospheric pressure and Naftidrofuryl infusion (N) on the TCpO2 is shown. At the central control site--5 cm below the midclavicular line--oxygen inhalation produced a significant increase in TCpO2, whereas there was no change after Naftidrofuryl infusion. At the 10 cm below-knee site, there were significant rises after oxygen inhalation alone, Naftidrofuryl a...

Iloprost inhalation has recently emerged as an alternative therapy for severe primary pulmonary hypertension. In the studies documenting the effect of iloprost inhalation therapy, hemodynamic variables have been measured invasively. We have followed a patient with primary pulmonary hypertension receiving iloprost inhalation therapy for 5 years using echocardiography to monitor changes in pulmon...

PURPOSE The purpose of this study was to determine the influence of 40% nitrous oxide/60% oxygen inhalation with scavenging on the behavioral and physiological parameters during routine pediatric dental procedures. METHODS Twenty-two subjects, aged 60-116 months, were randomized into a double blind, cross-over study design and administered alternately either 40% nitrous oxide/60% oxygen or 10...
