BACKGROUND Bacterial mediastinitis is a severe complication after open heart surgery. The infection causes prolonged hospitalization and an increased mortality risk. Observations from orthopaedic surgery showed that the suction catheter used during surgery is commonly contaminated with bacteria. The aim of this study was to describe the prevalence of suction catheter contamination in cardiac su...
Fifty-eight patients with mild to moderately severe acute pancreatitis were randomly allocated to treatment with or without nasogastric suction (27 and 31 patients respectively). Intravenous fluids and pethidine hydrochloride were also given. The two groups were comparable clinically at the start of the study. There were no differences between the two groups in the mean duration of the followin...
Background and Objectives: Some nursing and medicine activities may increase the production of free radicals in patients. Therefore, this study was performed to determine the effect of suction with a tube located inside of the trachea on the amount of oxidative stress indexes in CABG patients. Matrial and Methods: This clinical study was performed on 35 patients which were under coroner vas...
Suction of endotracheal tube in ICU can cause hemodynamic changes. We compare the effect of lidocaine , fentanyl and placebo on reducing hemodynamic changes following suction in ICU patient. Patients were divided into three groups , each containing twenty ...
Introduction: Although suction is an important nursing intervention in neonates under ventilation, it can lead to complications such as pain, respiratory distress, hypoxemia, bronchospasm and hospital infection. The purpose of this study was to determine The relationship between pain score and its effective indices in neonatal endotracheal open suction under ventilator in the neonatal intensive...
An analysis has been performed to study magneto-hydrodynamic MHD squeeze flow between two parallel infinite disks where one disk is impermeable and the other is porous with either suction or injection of the fluid. We investigate the combined effect of inertia, electromagnetic forces, and suction or injection. With the introduction of a similarity transformation, the continuity and momentum equ...
The rate and magnitude of buccal expansion are thought to determine the pattern of water flow and the change in buccal pressure during suction feeding. Feeding events that generate higher flow rates should induce stronger suction pressure and allow predators to draw prey from further away. We tested these expectations by measuring the effects of prey capture kinematics on suction pressure and t...
Suction feeding is central to prey capture in the vast majority of ray-finned fishes and has been well studied from a detailed, mechanistic perspective. Several major trade-offs are thought to have shaped the diversification of suction-feeding morphology and behavior, and have become well established in the literature. We revisited several of these expectations in a study of prey capture morpho...
BACKGROUND The vital issue of protecting the airway and maintaining ventilation in preterm infants makes tracheal suctioning an important procedure. The decision to use closed or open endotracheal suction method depends on the clinical status of infants and the nurses' skills and preferences. OBJECTIVES The current study aimed to compare the two methods based on the perceptions of the nurses ...
OBJECTIVES This study attempted to identify which is the more effective suction system. The objective was to compare open versus closed suction systems according to a systematic review. METHODS A search of scientific literature was conducted in MedLine, LILACS and Cochrane between 1997 and August 2007 using the key words: endotracheal suction and closed suction. Included were articles that co...
