Agreement Between Alberta Infant Motor Scale Assessment and Maternal Perception of Motor Development in Full-Term Infants.

Objectives: To verify the agreement between the Alberta Infant Motor Scale assessment and maternal perception of the motor development in full-term infants.

Methods: This is a cross-sectional study involving 161 infants and mothers. Children were assessed with the Alberta Infant Motor Scale (AIMS) for motor developmental classification.

INTRA- AND INTER-RATER RELIABILITY OF A BIOPHOTOGRAMMETRIC ASSESSMENT PROTOCOL FOR PRETERM INFANTS.

Objective: To measure the intra- and inter-rater reliability of a biophotogrammetric assessment protocol for thoracoabdominal motion in preterm infants.

Methods: This is an analytical cross-sectional study. Footage of 40 preterm infants was made in two views (lateral and anterior).

Temporal assessment of neonatal pain after airway aspiration.

Objective: To temporally assess a painful stimulus in premature infants using 3 neonatal pain scales.

Methods: A total of 83 premature infants were observed during airway aspiration by 3 evaluators (E1, E2 and E3) using 3 pain assessment scales (Neonatal Facial Coding System - NFCS; Neonatal Infant Pain Scale - NIPS; and Premature Infant Pain Profile - PIPP) at 5 time points: T1 (before airway aspiration), T2 (during airway aspiration), T3 (1 minute after airway aspiration), T4 (3 minutes after airway aspiration), and T5 (5 minutes after airway aspiration). Light's Kappa (agreement among examiners and among scales at each time point) and the McNemar test (comparison among time points) were used considering p < 0.

NEONATAL PAIN: CHARACTERIZATION OF THE PHYSIOTHERAPIST'S PERCEPTION IN THE NEONATAL INTENSIVE CARE UNIT.

Objective: To describe the perception of physiotherapists in neonatal units regarding pain, the use of measurement scales and strategies that minimize pain.

Methods: Interviews were conducted with physiotherapists in hospitals with neonatal units between 2013 and 2015 in Rio de Janeiro. The questions concerned the knowledge of the feeling of pain, from its recognition to its care or treatment.

On the crucial ventilatory setting adjustment from two- to one-lung ventilation.

Lung mechanics, histology, oxygenation and type-III procollagen (PCIII) mRNA were studied aiming to evaluate the need to readjust ventilatory pattern when going from two- to one-lung ventilation (OLV). Wistar rats were assigned to three groups: the left lung was not ventilated while the right lung received: (1) tidal volume (V(T))=5 ml/kg and positive end-expiratory pressure (PEEP)=2 cm H(2)O (V5P2), (2) V(T)=10 ml/kg and PEEP=2 cm H(2)O (V10P2), and (3) V(T)=5 ml/kg and PEEP=5 cm H(2)O (V5P5). At 1-h ventilation, V5P2 showed hypoxemia, alveolar collapse and impaired lung function.

Lung mechanics and histology during sevoflurane anesthesia in a model of chronic allergic asthma.

Background: There are no studies examining the effects of sevoflurane on a chronically inflamed and remodeled airway, such as that found in asthma. In the present study, we sought to define the respiratory effects of sevoflurane in a model of chronic allergic asthma. For this purpose, pulmonary mechanics were studied and lung morphometry analyzed to determine whether the physiological modifications reflected underlying morphological changes.

Effects of dexmedetomidine on respiratory mechanics and control of breathing in normal rats.

Dexmedetomidine is a highly selective and specific alpha(2)-adrenergic agonist, with sedative, analgesic, and sympatholytic activities. The aim of the present study was to define the effects of DMED in respiratory mechanics in normal rats. In addition, lung morphometry was studied to determine whether the physiological changes reflected underlying morphological changes defining the sites of action of dexmedetomidine.

Lung parenchyma remodeling in a murine model of chronic allergic inflammation.

This study tested the hypotheses that chronic allergic inflammation induces not only bronchial but also lung parenchyma remodeling, and that these histologic changes are associated with concurrent changes in respiratory mechanics. For this purpose, airway and lung parenchyma remodeling were evaluated by quantitative analysis of collagen and elastin, immunohistochemistry (smooth-muscle actin expression, eosinophil, and dendritic cell densities), and electron microscopy. In vivo (airway resistance, viscoelastic pressure, and static elastance) and in vitro (tissue elastance, resistance, and hysteresivity) respiratory mechanics were also analyzed.

Time course of respiratory mechanics and pulmonary structural remodelling in acute lung injury.

The aim of this study was to evaluate the time course of in vivo and in vitro respiratory mechanics and examine whether these parameters could reflect the temporal changes in lung parenchyma remodelling in paraquat (PQ)-induced lung injury. Measurements were done 1, 3 and 8 weeks after the intraperitoneal (i.p.
