The relationship between Cormic Index and uterine contractions' pattern in the active phase of the first stage of labour.

Uterine contractions are indicators of labour progress. The relationship between anthropometric indices and types of childbirth has been investigated. One of these indices is referred to as the Cormic Index, which provides an estimation of the sitting height and leg length. This cross-sectional study was performed to determine the relationship between the Cormic Index and the uterine contractions' pattern in the active phase of the first stage of labour. The standing and sitting heights of 150 pregnant women were measured to calculate the Cormic Index. Then, two Cardiotocographic traces were recorded during the 3 to 5 and 6 to 8 centimetres' dilations, by which the uterine contractions' pattern were determined. The mean Cormic Index was 51.84 ± 2.62. The results indicated that the Cormic Index had a positive linear correlation with MTIME (frequency of contractions) in the first monitoring episode and SDTIME (regularity of contractions) in the first and the second monitoring episode, which was significant (p < .05). However, there was no significant correlation between the Cormic Index and F:R ratio (shape of contractions) in both monitoring episodes. With the rise of the mother's Cormic Index, the frequency of contractions in the acceleration phase, and also their regularity in the acceleration phase and the phase of the maximum slope, were decreased during the active phase of labour.IMPACT STATEMENTWhat is already known on this subject? Uterine Contraction as an indicator of labour progress enforces cervical dilation. If uterine activity is analysed through electronic methods, one could assess labour outcome through some patterns of the contractions. Anthropometry provides a quick determination of the body proportions. The Cormic Index provides an estimation of the upper and lower body length. Several studies have investigated the relationship between the anthropometric indices and the types of childbirth. Despite the various approaches available, there is no objective means of precisely distinguishing the fact that whether labour can be successful in effecting vaginal delivery or not and diagnosis of dystocia still relies on the trial of labour.What do the results of this study add? The results of this study add to the growing body of research on the progression of labour that Cormic Index has a positive linear correlation with the frequency of contractions in acceleration phase, and with the regularity of contractions in the acceleration phase and the phase of maximum slope.What are the implications of these findings for clinical practice and/or further research? The results can help professionals to evaluate the progress of labour based on the type of uterine contractions in the latent phase or the early active phase of labour using the Cormic Index.

Valsalva retinopathy in pregnancy: a case report.

BACKGROUND: Valsalva retinopathy is a known medical condition which happens after valsalva maneuver. The aim of this study was to report a case of young asian pregnant female presented with acute visual loss due to the valsalva retinopathy, followed by spontaneous visual recovery. CASE PRESENTATION: A case of 23 years-old pregnant Asian female with 31 weeks of gestation presented with history of a sudden decrease in vision in her left eye from seven hours prior to the visit. Based on clinical findings, laboratory test and imaging studies, the diagnosis of Valsalva retinopathy was confirmed. Subsequently, her normal vision was returned during three months with no intervention. CONCLUSION: Pregnancy is a risk factor for Valsalva retinopathy. Valsalva retinopathy generally has a good prognosis. Vision usually returns to normal over a short period of time and requires only observation.

Prenatal and cardiovascular outcome in pregnant patients with dyspnea.

BACKGROUND: Pregnancy is a physiologic phenomenon in women, which leads to significant hemodynamic changes in cardiovascular system. Many patients reach reproductive age due to improvements in diagnosis and treatment of cardiac diseases. Dyspnea is a common complaint in pregnant women and can be a sign to refer patients for an easy and feasible workup such as echocardiography. OBJECTIVES: We aimed to evaluate dyspnea as a common complaint in pregnant women and its prenatal outcome. PATIENTS AND METHODS: Pregnant patients with dyspnea NYHA class > II were included. A thorough physical examination and routine lab tests were performed. Echocardiography was performed to rule out previous cardiac and lung diseases, anemia and thyroid disorders. It was repeated monthly till one month after delivery. Collected data was analyzed after one year. RESULTS: Fifty patients were enrolled with a mean age of 30.49 ± 6.34 years. 58% of them, had NYHA class II, 40% III and 2% IV. Pulmonary rales were diagnosed in 8% and palpitation in 80%, while all had normal lab tests. Mean EF value was 52.26 ± 6.80; 54% had valvular diseases and 12% had pulmonary hypertension. Cesarean section was performed in 26, preeclampsia occurred in 7 and 21 had preterm labor. Three neonates had anomalies and six had an Apgar score below six. Mean birth weight was 2897 ± 540.00 grams. A significant association was found between NYHA Class with valvular disease (P = 0.007) and sys PAP (P = 0.036); however, it had an inverse correlation with LV EF (P = 0.06). CONCLUSIONS: Dyspnea may coincide with cardiac dysfunction and poor prenatal outcome in pregnant patients. In such cases echocardiography is a feasible screening tool.
