Introduction: In newborns delivered by cesarean section, there is less chest compression and little amount of fluid is drained by gravity, which temporarily reduces thoracoabdominal mobility.
Objetive: The objective of this study is to evaluate the impact of the type of delivery on newborns Thoracoabdominal Mobility.
Methods: This is a cross-sectional study with newborns of gestational age between 37 and 41 weeks, of both sexes, with up to 72 hours of life, breathing in ambient air and born by normal delivery or cesarean section. The Thoracoabdominal Mobility was evaluated by videogrammetry using MATLAB Software and considered, in metric units (cm2), as the difference between the highest and lowest thoracoabdominal expansibility for each respiratory cycle.
Results: Twenty-six infants were included, 11 were male and 50% were born by cesarean section. The mean gestational age was 39 ± 0,9 and 28 ± 18 hours of life. The mobility, difference between greater and lesser expansion, of the thoracic area in vaginal and cesarean delivery was 6 ± 3 cm2 and 7 ± 5 cm2 and the abdominal area was 29 ± 22 cm2 and 21 ± 14 cm2, respectively. This difference was not statistically significant between the two types of delivery for the thoracic area, but was statistically different for the abdominal area (p= 0.01). And the higher the respiratory rate, the lower the abdominal mobility (r= -0.57, p= 0.02).
Conclusion: The data indicate that the type of delivery seems to influence abdominal mobility and respiratory rate. In the studied sample, newborns with cesarean section presented lower abdominal mobility.
