Objective: The aim of this study was to evaluate the heart and respiration rates, mean arterial pressure, temperature and peripheral oxygen saturation of low-weight preterm newborns, before and after the application of kangaroo mother care. Method: Twenty--two healthy low-weight preterm newborns of both sexes were studied. None of them had neurological, cardiac and/or respiratory deficiencies. Assessments were made after the newborn had been left in an ordinary cot for 30 minutes and after 30 minutes of kangaroo mother care, on three consecutive days. For these evaluations, a heart monitor with a device for non-invasively measuring mean arterial pressure, a sensor for pulse oximetry, a thermometer and a chronometer were utilized. Results: There were no significant changes in mean arterial pressure (p> 0.05) or heart rate (p> 0.05) after applying kangaroo mother care. However, there were significant increases in axillary temperature (p< 0.05) and peripheral oxygen saturation (p< 0.05), and a significant decrease in respiration rate (p< 0.05). Conclusion: Kangaroo mother care promotes improvement in body temperature, increased peripheral oxygen saturation (thus improving tissue oxygenation), and decreased respiration rate (thus providing greater respiratory comfort for the newborns). This suggests that kangaroo mother care contributes towards beneficial alterations in the low-weight newborns' vital signs.

© Revista Brasileira de FisioterapiaStudy on pulmonary volumes and thoracoabdominal mobility in morbidly obese women undergoing bariatric surgery, treated with two different physical therapy methods ), before surgery and 15 and 30 days after surgery. The candidates were evaluated with regard to measurements of inspiratory reserve volume (IRV), expiratory reserve volume (ERV), inspiratory capacity (IC) and thoracoabdominal mobility, by means of spirometry and cirtometry, respectively. CRP consisted of diaphragmatic respiratory exercises, deep fractionated inspiration and respiratory exercises associated with upper limb movement. One set of 10 repetitions of each exercise was carried out twice daily while hospitalized. For TEDS, two electrodes were placed on the parasternal region, next to the xiphoid process, and another two between the sixth and seventh intercostal spaces, bilaterally on the anterior axillary lines. Friedman's test was used to compare repeated measures within groups, and the Mann-Whitney test for comparisons between groups. P values <0.05 were taken to be statistically significant. Results: The IRV, ERV and thoracoabdominal mobility measurements increased significantly in the CRP+TEDS group. In contrast, the IC measurements decreased significantly both in the CRP and in the CRP+TEDS groups. Conclusion: The obese women who underwent bariatric surgery and received postoperative CRP+TEDS presented greater gains in some of the pulmonary volumes and improvements in the amplitude of respiratory movements.
