This study objectives were to measure the sound pressure levels found in the pediatric intensive care unit in a federal institution of Rio de Janeiro; to verify differences in noise levels during the morning and afternoon; to confront the sound pressure levels found against acceptable levels according to national and international noise organizations; to count the quantity of alarms triggered by each type of medical care equipment selected (multiparameter monitor, mechanical ventilator and infusion pump); to verify the relevance in the scientific world about pediatric intensive care unit noise through bibliometrics and to address the trinomial care technology - noise - implications on care. It’s an observational, exploratory, quantitative study, organized in three steps: Parameter collection and decibel meter calibration - data were based on the study by Salú, et al (2015) ; Data collection: 40 hours of discontinued observation (8am to 16pm) on different days for a period two months using two decibel meters; Data processing: An Excel spreadsheet was created for the database and data analysis was performed with the help of Microsoft Office Excel 2010 and Program R, organized into graphs and tables. 61% of the alarms corresponded to the mechanical ventilator; Bed E had the lowest standard deviation (SD = 2.945) and the highest median (69.5dBA). Even by removing the E bed from the analysis, there is a significant difference (p <0.001) between sound pressure levels. The median of the afternoon (28.2dBA); and morning (26.1dBA). Mechanical fan and monitor generated higher sounds; the pediatric intensive care unit has considerably exceeded that recommended by national and international noise organizations; afternoon generated higher sounds than morning.

Background NP (NP) especially YAP (ventilator-associated pneu-monia) is the most common infection in intensive care unit, whichcorrelates with the increasing of morbidity and mortality. Thereare some risk factors for development ofNP, the most importantone is duration of mechanical ventilator and reintubation.Objective To determine the correlation between NP and use ofmechanical ventilator in pediatric intensive care unit (PICU).Methods A matched case control study was conducted at Dr.Sardjito Hospital on all patients admitted to the PICU from2004 until 2006. Case group was defined as all patients who hadNP; age and sex matched control group included all patients notdiagnosed as NP. Statistical analysis was done by using chi-squareand t-tests as appropriate. Logistic regression analysis was doneto determine the role of risk factors.Results One-hundred and forty-one patients were included inthis study. The incidence of NP was 25. 7%. There was associa-tion between using mechanical ventilator (OR 1.08; 95%CI 1.07;8.20, P=0.036) and duration of using mechanical ventilator morethan four days (OR 1.75, 95%CI 1.87;18.02) with developmentof NP. There was a significant difference in event free survival ofNP between those using mechanical ventilator group and thosenot using mechanical ventilator group (P<O.OOl).Conclusion There is an association between the use of mechani-cal ventilator and duration of use of mechanical ventilator morethan four days with the development of NP
