Maternal Height and ‘Shoe Size’ as Predictors of Intrapartum Complications in Labor with Occiput Posterior Malposition

Abstract

ABSTRACT:BACKGROUND:Although most women have anormal labour and birth, there are sometimes complication occurring due to multiple factors,occiput posterior postion represent achallenges in diagnosis,labour& intrapartum complication careOBJECTIVE: To evaluate maternal height and shoe size correlates with complications associated with occiput posterior ma position during labor.Type of the study; case controlMETHODS:A total of 45 primigravida women with android pelvis were chosen versus 45 with gynecoid pelvis according to clinical pelvimetry,Their shoe size and height were recorded. In addition women in both groups were scrutinized for occiput posterior and labor complications associated with condition including secondary arrest of dilatation, deep transverse arrest and cesarean for failed assisted vaginal delivery. Labor duration with regard to the first and second stage was also recorded for both groups and linked to shoe size and maternal height.RESULTS:The odd ratio for secondary arrest of dilatation, deep transverse arrest and failed assisted vaginal delivery were significantly higher among women with android pelvis than gynecoid ; 4.8, 5.6 and 4.5, respectively. A significant correlation between shoe sizes, maternal height versus duration of the first and second stage; P Value is P < 0.0001. Cluster analysis showed that women with shoe size between 37 cm to 40 cm are most likely to have intrapartum complication and failed assisted vaginal delivery. The rate of complications was higher in the android group than control gynecoid pelvis. CONCLUSION: Some correlation could be concluded between maternal shoe size and possibility of cesarean section for deep transverse arrest among women with android pelvis. However due to the anthropometric variations among women the results of this study could only be applied to patients covered by AL Yarmook Teaching Hospital including south and west of Baghdad city. Further studies are required to have better understanding of this vital subject.
