OBJECTIVE. To evaluate the effect of oral hygiene with 0.12% chlorhexidine gluconate on the incidence of nosocomial pneumonia and ventilator-associated pneumonia (VAP) in children undergoing cardiac surgery. DESIGN. Prospective, randomized, double-blind, placebo-controlled trial. SETTING. Pediatric intensive care unit (PICU) at a tertiary care hospital. patients. One hundred sixty children undergoing surgery for congenital heart disease, randomized into 2 groups: chlorhexidine (n = 87) and control (n = 73). INTERVENTIONS. Oral hygiene with 0.12% chlorhexidine gluconate or placebo preoperatively and twice a day postoperatively until PICU discharge or death. RESULTS. Patients in experimental and control groups had similar ages (median, 12.2 vs 10.8 months; P =. 72) and risk adjustment for congenital heart surgery 1 score distribution (66% in category 1 or 2 in both groups; P =. 17). The incidence of nosocomial pneumonia was 29.8% versus 24.6% (Pp. 46) and the incidence of VAP was 18.3% versus 15% (Pp. 57) in the chlorhexidine and the control group, respectively. There was no difference in intubation time (P =. 34), need for reintubation (P =. 37), time interval between hospitalization and nosocomial pneumonia diagnosis (P =. 63), time interval between surgery and nosocomial pneumonia diagnosis (P =. 10), and time on antibiotics (P =. 77) and vasoactive drugs (P =. 16) between groups. Median length of PICU stay (3 vs 4 days; P =. 53), median length of hospital stay (12 vs 11 days; P =. 67), and 28-day mortality (5.7% vs 6.8%; P =. 77) were also similar in the chlorhexidine and the control group. CONCLUSIONS. Oral hygiene with 0.12% chlorhexidine gluconate did not reduce the incidence of nosocomial pneumonia and VAP in children undergoing cardiac surgery.

Objective: This study assessed the percentage of the amount of dentifrice loaded onto the toothbrush that is ingested by children, taking into account age, the amount of dentifrice used during toothbrushing, and the dentifrice flavor. Methods: The sample consisted of 155 children of both genders attending public kindergartens and schools in Bauru, Brazil, divided into 5 groups (n = 30-32) of children aged 2, 3, 4, 5 and 6 years old. The dentifrices used were Sorriso(TM) (1219 ppm F, peppermint-flavored) and Tandy(TM) (959 ppm F, tutti-frutti-flavored). The assessment of fluoride intake from dentifrices was carried out six times for each child, using 0.3, 0.6, and 1.2 g of each dentifrice, following a random, crossover distribution. Brushing was performed by the children or their parents/caregivers according to the home habits and under the observation of the examiner. Fluoride present in the expectorant and on toothbrush was analyzed with an ion-specific electrode after HMDS-facilitated diffusion. Fluoride ingestion was indirectly derived. Results were analyzed by 3-way repeated-measures anova and Tukey`s tests (P < 0.05) using the percent dentifrice ingested as response variable. Results: Age and percent dentifrice ingested for both dentifrices, and the three amounts used were inversely related (P < 0.0001). Percent dentifrice ingested was significantly higher after the use of Tandy(TM) under all conditions of the study when compared with Sorriso(TM) (P < 0.0001). Significant differences were observed when brushing with 0.3 g when compared with 1.2 g, for both dentifrices tested (P < 0.05). Conclusions: The results indicate that all variables tested must be considered in preventive measures aiming to reduce the amount of fluoride ingested by young children.
