The objective of this study was to investigate serum adenosine deaminase (ADA) activity as a marker of T lymphocyte activation and parameters of oxidative stress and antioxidant defence in hyperemesis gravidarum (HG). Serum ADA activity, malondialdehyde (MDA), catalase (CAT) and glutathione peroxidase (GPx) levels were investigated in 40 pregnant women with the HG and 40 with healthy pregnancies, in a descriptive study. Although serum ADA and CAT were measured to be higher in HG group, the difference was not significant. Serum MDA and GPx levels were significantly elevated in women with HG when compared with those without HG. The significance of changes in lipid peroxidation and T-cell activation in the pathogenesis of HG and whether this is a cause or a compensatory reaction to HG requires further investigations with larger multicentre trials.

In this study we aimed to explore the effects of epidural analgesia achieved by a combination of low-dose bupivacaine and fentanyl infused through an epidural catheter on mother, foetus and labour process in nulliparous at-term pregnant women during vaginal delivery. This study was designed in a prospective, randomised controlled manner. Epidural analgesia was achieved in 50 nulliparous women. Fifty nulliparous women did not undergo epidural analgesia procedure. The duration of the first stage of labour was significantly shortened, while the second stage was significantly lengthened in pregnant women who underwent epidural analgesia (p < 0.05). In conclusion, starting epidural analgesia application during the active phase of the first stage of labour may shorten the duration of the first stage compared with the group of nulliparous women not undergoing epidural analgesia. The factor that has an impact on this may be the addition of fentanyl to bupivacaine used for epidural analgesia. [ABSTRACT FROM AUTHOR]
