Developing an instrument to support oral care in the elderly

GERODONTOLOGY, Issue 1 2003
Yasunori Sumi
Abstract Background: The dramatic increase in the number of dependent elderly in developed countries has created a great need for their improved oral care. However, optimal oral care by caregivers is not possible because of time constraints, difficulty involved in brushing other individuals' teeth, lack of co-operation, and the lack of perceived need. Therefore, the development of an effective instrument simplifying and supporting oral care to relieve the strain on caregivers is a matter of some urgency. Purpose: In order to clean the mouths of elderly dependent patients, we have developed a new oral care support instrument (an electric toothbrush in combination with an antibacterial-agent supply and suction system). The purpose of the present study was to develop and evaluate a new oral care support instrument. Methods: a) Plaque removal study: The plaque- removing ability of this new instrument in 70 outpatients was compared with the Plak Control D9011 (Braun Gillette Japan Inc.) as a control by means of the Turesky modification of the Quigley and Hein plaque index, b) Clinical study: The subjects were 10 dependent elderly who received oral care using the new oral care support instrument for two weeks. The plaque and gingival indices were used for clinical evaluations. Results: a) Plaque removal study: Brushing with the new oral care support instrument removed significantly more plaque than with the Plak Control D9011. b) Clinical study: The new oral care support instrument allows a more effective removal of dental plaque and shows a significant improvement in the gingival indices in dependent elderly. Conclusion: It is concluded that the new oral care support instrument is effective and can be recommended for oral care in the dependent elderly. [source]

Drag reduction by flow separation control on a car after body

INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 11 2009
Mathieu Rouméas
Abstract New development constraints prompted by new pollutant emissions and fuel consumption standards (Corporate Average Economy Fuel) require that automobile manufacturers develop new flow control devices capable of reducing the aerodynamic drag of motor vehicles. The solutions envisaged must have a negligible impact on the vehicle geometry. In this context, flow control by continuous suction is seen as a promising alternative. The control configurations identified during a previous 2D numerical analysis are adapted for this purpose and are tested on a 3D geometry. A local suction system located on the upper part of the rear window is capable of eliminating the rear window separation on simplified fastback car geometry. Aerodynamic drag reductions close to 17% have been obtained. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Closed suctioning system: Critical analysis for its use

JAPAN JOURNAL OF NURSING SCIENCE, Issue 1 2010
Nahoko HARADA
Abstract Aim:, To determine the efficacy and effectiveness of the closed suctioning system. Method:, Literature review articles were accessed from the following databases: PubMed, EMBASE, CINAHL, and Cochrane Library. The literature review criteria included: all publication styles except meta-analysis, participants that were ,18 years, written in English, and published between 1973 and 2008. Results:, This literature review revealed that the efficacy and effectiveness of the closed suctioning system remains to be demonstrated. The device manufacturers' studies focused on cost reduction, cross-contamination, and preservation of the oxygen saturation of patients during endotracheal suctioning; however, the clinical studies focused on the use of closed suctioning systems to prevent ventilator-associated pneumonia. The reviewed studies had small sample sizes with heterogeneous demographics and non-randomized controls. Recent studies suggest that closed suctioning systems are no better than open suctioning systems in terms of mortality, morbidity, or the cost-benefit ratio. A few studies did indicate that the closed suctioning system might reduce the loss of lung volume and oxygen desaturation. Conclusion:, The studies reviewed in this article suggest that the evidence on the efficacy and effectiveness of closed suctioning systems is inconclusive. Only limited populations will benefit clinically from the use of this device. There is a need for further studies with randomized controlled trials to explore the use of closed suction systems and to update current clinical practise guidelines. [source]

A Scandinavian survey of drug administration through inhalation, suctioning and recruitment maneuvers in mechanically ventilated patients

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2009
C. GRIVANS
Background: The aim was to describe current practices for drug administration through inhalation, endotracheal suctioning and lung recruitment maneuvers in mechanically ventilated patients in Scandinavian intensive care units (ICUs). Methods: We invited 161 ICUs to participate in a web-based survey regarding (1) their routine standards and (2) current treatment of ventilated patients during the past 24 h. In order to characterize the patients, the lowest PaO2 with the corresponding highest FiO2, and the highest PaO2 with the corresponding lowest FiO2 during the 24-h study period were recorded. Results: Eighty-seven ICUs answered and reported 186 patients. Positive end-expiratory pressure (PEEP) levels (cmH2O) were 5,9 in 65% and >10 in 31% of the patients. Forty percent of the patients had heated humidification and 50% received inhalation of drugs. Endotracheal suctioning was performed >7 times during the study period in 40% of the patients, of which 23% had closed suction systems. Twenty percent of the patients underwent recruitment maneuvers. The most common recruitment maneuver was to increase PEEP and gradually increase the inspiratory pressure. Twenty-six percent of the calculated PaO2/FiO2 ratios varied >13 kPa for the same patient. Conclusion: Frequent use of drug administration through inhalation and endotracheal suctioning predispose to derecruitment of the lungs, possibly resulting in the large variations in PaO2/FiO2 ratios observed during the 24-h study period. Recruitment maneuvers were performed only in one-fifth of the patients during the day of the survey. [source]
