BACKGROUND Guidelines recommending head of bed (HOB) elevation greater than 30º to prevent ventilator-associated pneumonia conflict with guidelines to prevent pressure ulcers, which recommend HOB elevation less than 30º. OBJECTIVES To examine the feasibility of 45º HOB elevation and describe and compare the occurrence of reflux, aspiration, and pressure ulcer development at 30º and 45º HOB el...

Ficus religiosa is being used in Ayurvedic and Malay traditional medicine for the treatment of various diseases including gastric ulcer. Considering the above claims, the present work was undertaken to validate the anti-ulcer potential of the ethanol extract of leaves of Ficus religiosa against in vivo aspirin induced ulcer and pylorus ligation assays. Gastric ulcers induced in Swiss albino rat...

Endotracheal tube colonization in patients undergoing mechanical ventilation was investigated. In the first part of this prospective study, the airway access tube was examined for the presence of secretions, airway obstruction and bacterial colonization, in cases undergoing extubation or tube change. In the second part of the study, the sequence of oropharyngeal, gastric, respiratory tract and ...

The present study was designed to determine the relationship between changes in gastric function caused by aging and the healing of gastric ulcers. Male Fischer-344 rats (young, 2 months; aged, 24-26 months) were used. Gastric ulcers were induced by luminal application of an acetic acid solution (60%, 0.2 ml, 45 sec). The basal and histamine-stimulated gastric acid secretions in aged animals we...

Introduction: Garlic (Allium Satiyum) is a plant widely used in traditional medicine. Its anti-hypertensive, lipid lowering, oxidative activities, anti-viral, anti-bacterial, anti-fungal properties have been proven. It has a tonic effects on stomach but its effects on gastric secretion is not known. Propose of study: To investigate the effect of garlic extract on basal and pentagastrin stimulat...

Thirty unselected subjects with chronic obstructive pulmonary emphysema were studied. The diagnosis in each instance was substantiated by fluoroscopic observation and evaluation of pulmonary function. Each patient was studied in the fasting state. Intubation was carried out under fluoroscopic control and an indwelling arterial needle was inserted. Continuous gastric suction was applied until su...

Background: Ethno-botanical information shows that Eremomastax speciosa is used in the traditional management of various stomach complaints including gastro-duodenal ulcers. Materials and Methods: In this study, we tested the cytoprotective potential of the whole plant methanol extract (100-200 mg/kg, p.o), against HCl/ethanol, absolute ethanol, cold/restraint stress rats, and pylorus legated r...

Introduction: The effect of esophageal distension (ED) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ED on gastric secretion. The aim of this study was to investigate the effect of ED on gastric acid and pepsin secretion and the mechanism(s) involved. Methods: Male adult Wistar rats (200-240 g) were anesthetized with urethane (1...
