Oxygen Therapy Debate Dear Editor, In response to the article, “Topical Hyperbaric Oxygen and Electrical Stimulation: Exploring Potential Synergy” (Ostomy/Wound Management. 2002;48(11):42-50), by definition, hyperbaric oxygen therapy involves the entire body, increased atmospheric pressure, and the patient breathing 100% oxygen. The increased oxygen pressure and oxygen concentration help wound ...
The effect of clonidine, a central alpha2-adrenoreceptor agonist on reduction of anxiety, producing sedation and attenuation hemodynamic changes, were assessed during thissemi-experimental study in one of the hospitals of Iran medical sciences university in Tehran, 1994. Fifty surgical patients of either sex, 18-60 years of age, with ASA physical status I or II, gave informed consent to ent...
Introduction: Intensive care unit is one of the most stressful wards for patients and it is estimated that 30 to70 percent of patients experience severe physiologic stress during admission. Some of the physiologic responses to stress include increase in metabolic rate with consequent increase in body temperature, increase in cardiac output and contraction power and subsequently increase in bloo...
Background: The Jigsaw technique is a modern method that enables the creation of positive learning environment.In this study, we aim to determine impact on students’ knowledge level regarding arterial blood pressure and their performance skill level. Material Methods: A quasi-experimental design study was conducted 60 first year nursing students atSakarya University. Students in control group r...
Objective- This study aims to determine the efficacy of propofol in grass carp anesthesia and to examine the impact of the drug on electrocardiogram, pH and blood gases in this fish species. Design- Experimental study. Animals- 120 apparently healthy grass carps, weighting between 1-2 kg. Procedure- Fishes were sorted randomly into 12 groups of 10 fish each. Five groups were anesthetized by bat...
To investigate the channels and neurotransmitters in the ventrolateral medulla (VLM) oblongata that are responsible for the maintenance of sympathetic tone and cardio-respiratory reflex regulation. Microinjections of excitant amino acid (glutamate, 100 nl, 100 mM), calcium channel blockers, agonists and antagonists were made throughout the VLM in anaesthetized rats. Arterial blood pressure, sym...
BACKGROUND When obtaining an arterial blood sample via percutaneous puncture, there is a risk of accidentally obtaining venous blood. Conventional methods of confirming arterial blood at the bedside, such as blood color and pulsatile return, can be misleading in patients with low blood pressure or hypoxemia. OBJECTIVE To determine if the arterial sampler filling time can be an accurate indic...
conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...
The role of nucleus tractus solitarius (NTS) in cardiovascular system regulation is controversial. On the other hand, the problem of hypertension in diabetic animals is the subject of many research programs. The aim of present study was to determine whether inactivation of NTS could affect blood pressure and heart rate in diabetic rats. To this end, stereptozotocin induced diabetic rats were an...
