Pulmonary function in advanced uncomplicated singleton and twin pregnancy.

Siddiqui AH, Tauheed N, Ahmad A, Mohsin Z - J Bras Pneumol (2014 May-Jun)

Bottom Line: Respiratory function was assessed in 50 women with twin pregnancies and in 50 women with singleton pregnancies (during the third trimester in both groups), as well as in 50 non-pregnant women.We found no significant differences between women with twin pregnancies and those with singleton pregnancies, in terms of respiratory function.Despite its higher physiological demands, twin pregnancy does not appear to impair respiratory function to any greater degree than does singleton pregnancy.

ABSTRACT

Objective: Pregnancy brings about significant changes in respiratory function, as evidenced by alterations in lung volumes and capacities, which are attributable to the mechanical impediment caused by the growing foetus. This study was undertaken in order to identify changes in respiratory function during normal pregnancy and to determine whether such changes are more pronounced in twin pregnancy than in singleton pregnancy.

Methods: Respiratory function was assessed in 50 women with twin pregnancies and in 50 women with singleton pregnancies (during the third trimester in both groups), as well as in 50 non-pregnant women. We measured the following pulmonary function test parameters: FVC; FEV1; PEF rate; FEV1/FVC ratio; FEF25-75%; and maximal voluntary ventilation.

Results: All respiratory parameters except the FEV1/FVC ratio were found to be lower in the pregnant women than in the non-pregnant women. We found no significant differences between women with twin pregnancies and those with singleton pregnancies, in terms of respiratory function.

Conclusions: Despite its higher physiological demands, twin pregnancy does not appear to impair respiratory function to any greater degree than does singleton pregnancy.

f02: Comparação dos parâmetros de função pulmonar entre os três gruposavaliados.

Mentions: No presente estudo, os valores para todos os parâmetros dos TFP foram menores entreas mulheres grávidas (ambos os grupos) do que entre as mulheres não grávidas (Tabela 3). As comparações entre vários pares degrupos (Tabela 4) mostraram que todos osparâmetros dos TFP, exceto a relação VEF1/CVF e a VVM, foramsignificativamente menores para as mulheres grávidas (gestação gemelar ou única) doque para as mulheres não grávidas. Os valores da VVM também foram menores entre asmulheres grávidas, embora a diferença não tenha sido significativa. Como se podeobservar na Figura 1, não houve diferençassignificativas na função pulmonar entre o grupo de mulheres com gestação gemelar e ogrupo de mulheres com gestação única.
