GALLO, Rubneide Barreto Silva et al. Level of cervical dilatation and request for regional analgesia by pregnant women with intact and ruptured chorioamniotic membrane. Rev. dor [online]. 2012, vol.13, n.1, pp. 30-34. ISSN 1806-0013. http://dx.doi.org/10.1590/S1806-00132012000100006.
BACKGROUND AND OBJECTIVES: Several factors change pain intensity during parturition, such as parity, chorioamniotic membranes rupture, cervical dilatation, in addition to cultural and environmental influences. So, this study aimed at checking the number of regional analgesia requests and the level of cervical dilatation at analgesia request by parturients with intact chorioamniotic membranes and those with chorioamniorrhexis. METHOD: This is a descriptive and retrospective study which analyzed 208 medical charts of primiparous parturients, 129 with intact chorioamniotic membranes and 79 with chorioamniorrhexis, assisted by the Women Health Center of Ribeirão Preto, SP, from November 2008 to May 2009. Mann-Whitney and Chi-square tests were used for statistical analysis with significance level p < 0.05 and 95% confidence interval. RESULTS: Regional analgesia was requested by 87.9% of the parturients selected for this research. Mean cervical dilatation for intact membrane patients was 6.26 ± 1.67 cm and for those with chorioamniorrhexis it was 6.11 ± 1.75 cm, without significant difference between groups (p = 0.12). With regard to the type of analgesia there has been predominance of double block, without significant differences between groups (p = 0.84). CONCLUSION: Most parturients have requested double block regional analgesia with mean cervical dilatation of 6 cm, with no difference between intact and ruptured chorioamniotic membranes.
