简要总结
This experimental study aims to verify the influence of the oral hygiene performance with chlorhexidine digluconate 0.12% in the development of VAP in children. The data collection begun in April, 2005 during the performance of the masters degree course dissertation entitled "Clinical study about the effect of the oral hygiene with chlorhexidine digluconate 0.12% in the oropharynx colonization of children in intensive care", being performed in a PICU of nine beds in a university hospital in the city of São Paulo, after approval of the Research Ethics Committee of the institution. The study is composed by three types of variables: Independent variable, dependent variables, and complementary variables. The categorical variables will be analyzed in accordance with the Person's Chi-Square test of or Fisher's exact test. The numerics will be submitted to the analysis of variance ANOVA or Kruskall Wallis. For variables with heterogeneous distribution between the groups, the multivariate analysis will be applied to the evaluation of the influence in the determination of the development risk of the dependent variable. The rejection level will be fixed in 0.05 of the nullity hypothesis.
详细描述
Recent progress in identification of oral microorganisms has shown that the oropharynx can be a site of origin for dissemination of pathogenic organisms to distant body sites, such as the lungs. THe aims of the study were to compare the oropharyngeal microbiological profile, VAP incidence, duration of mechanical ventilation, and length of stay in the intensive care unit of children receiving mechanical ventilation who had pharmacological or nonpharmacological oral care.
A randomized and controlled study has been performed in a pediatric intensive unit in São Paulo, Brazil. The children are randomly assigned to an experimental group that received oral care with use of 0.12% chlorhexidine digluconate or a control group that received oral care without an antiseptic. Oropharyngeal and tracheal secretions were collected and cultured on days 0, 2, and 4, and at discharge.

研究组 & 干预措施
0.12% Chlorhexidie Digluconate
Oral care included use of an oral gel containing chlorhexidine digluconate 0.12% as an active ingredient (chlorhexidine digluconate 0.12%; methylcellulose gel 2.12%, 25 g; gooseberry syrup, 4 drops; menthol solution 50%,3 drops; and distilled water, to 30 g).The gel is applied on a toothbrush, and the teeth are cleaned in quadrants; all teeth surfaces are cleaned (vestibular,lingual, occlusal, and incisal). After each quadrant was cleaned, 10 mL of water (dispensed via a syringe) is used to rinse the quadrant and continual aspiration is used to remove all the gel and debris. After all the teeth are cleaned, the ventral surface of the tongue is brushed with posteriorto- anterior movements.
干预措施: 0.12% Chlorhexidine Digluconate (Drug)
Toothbrushing
This group received the same oral care that experimental group with the use of a similarly formulated gel without the antiseptic agent.The gel is applied on a toothbrush, and the teeth are cleaned in quadrants; all teeth surfaces are cleaned (vestibular, lingual, occlusal, and incisal). After each quadrant is cleaned, 10 mL of water (dispensed via a syringe) is used to rinse the quadrant and continual aspiration is used to remove all the gel and debris. After all the teeth are cleaned, the ventral surface of the tongue is brushed with posteriorto-anterior movements.
干预措施: Toothbrushing (Other)
