Brief summary

Objective: To evaluate and compare the strength of respiratory muscles in women in the immediate postpartum vaginal and cesarean delivery. Methods: This study was conducted in a public maternity the coast of Sao Paulo, with a population of women in immediate postpartum period, the same were separated into two groups: vaginal delivery (VDG) and cesarean delivery (CDG), and evaluated by a form of data collection on the current pregnancy, childbirth and the data manuvacuometria held 24 and 48 hours postpartum. Results: The sample comprised 29 women and 30 VDG in the CDG. The average age was 24.75 (+/- 4.95) in VDG and 24.10 (+/- 4.72) in PDG. In both groups there was a decrease in inspiratory muscle strength (IMS) and expiratory (EMS) in relation to the predicted value in the 1st PP and 2nd PP (VDG / IMS - 1 PP: -44.07 +/- 12.72; 2nd PP: -56.79 +/- 15.54; PDG / IMS - 1 PP: -37.03 +/- 9.54; 2nd PP: -49.13 +/- 14.69 / VDG / EMS - 1st PP: 41.45 +/- 16.52; 2nd PP: 50.35 +/- 21.83; PDG / EMS - 1st PP: 32.93 +/- 5.05; 2nd PP: 37.63 +/- 8.93). When the groups were compared inspiratory muscle strength (IMS) and expiratory (EMS), the VDG maintained higher the CDG, the 1st and 2nd PP PP (PP 1: -44.07 +/- 12.72 vs. -37.03 +/- 9.5; 2nd PP: -56.79 +/- 15.54 vs. -49.13 +/- 14.69 / 1 PP: 41.45 +/- 16.52 versus 32.93 +/- 5.05; 2nd PP: 50.35 +/- 21.83 versus 37.63 +/- 8.93.) Conclusion: Regardless of the type of delivery was significantly lower in respiratory muscle strength in the immediate postpartum period. However, women in post-cesarean delivery had higher drop in inspiratory and expiratory muscle strength compared in women after vaginal delivery.

Interventions

This observational trial was conducted in the maternity of a public hospital in Sao Paulo/Brasil. We evaluated the strength of respiratory muscles, using manovacuometry technique, through maximal respiratory pressures on two occasions, twenty-four and forty-eight hours after delivery. Women in vaginal postpartum period were compared with women in post-cesarean section. In addition, we performed the calculation of the predicted volue for maximal respiratory pressures of all women who participate
