Effect of childbirth education on the perceptions of childbirth and breastfeeding self-efficacy and the obstetric outcomes of nulliparous women*,**,**.

In this quasi-experimental and prospective study, we aimed to determine the effect of education about childbirth on the perceptions of nulliparous women regarding the experience of childbirth, obstetric outcomes (e.g., type of delivery, use of induction, and instrument-assisted delivery), and breastfeeding self-efficacy. The study population comprised 121 women, of whom 64 and 57 were classified into the education and control groups, respectively. Study data were collected using a participant identification form, the Perception of Birth Scale, Visual Analog Scale, and Breastfeeding Self-Efficacy Scale-Short Form. Compared to the control group, participants in the education group held significantly more positive birth-related perceptions (p = 0.000) and experienced a lower level of pain during delivery (p = 0.016). However, education did not affect the obstetric outcomes. During the first month postpartum, a higher level of breastfeeding self-efficacy was reported by mothers in the education group than by those in the control group. In conclusion, systematic childbirth education positively affected the mothers' perceptions of the childbirth experience and their breastfeeding self-efficacy, but had no effect on the type of delivery or other birth-related obstetric interventions.

Dose-Dependent Anti-Inflammatory Effect of Ketamine in Liver Ischemia-Reperfusion Injury.

Introduction: Hepatic ischemia-reperfusion (I/R) injury is commonly observed in severe sepsis, hemorrhagic shock, liver transplantation, hepatic resection, and major trauma. Ketamine suppresses the production of cytokines, such as IL-6 and TNF-α, via NF-κB inhibition. We investigated the anti-inflammatory effects of ketamine in liver I/R injury. Materials and Methods: Female Wistar-Albino rats (n = 18), weighing 150-200g, were divided into three groups (n = 6 each). Group I underwent reperfusion for 4h following 30 min of ischemia. Group II received 2.5 mg/kg ketamine IM following 30 min of ischemia and 4h of reperfusion and Group III received 10 mg/kg ketamine IM following 30 min of ischemia and 4h of reperfusion. Blood samples were obtained before and after ischemia and reperfusion. MDA, AST, ALT, TNF-α, IL-1ß, IL-6, and NO levels were determined. Liver tissue samples were evaluated histologically. Results: Increased TNF-α, IL-1ß, and IL-6 levels were observed in all groups post-ischemia versus pre-ischemia (p <0.05). The TNF-α, IL-1ß, and IL-6 levels in Group III increased less than they did in Groups I and II (p <0.05). Higher MDA, NO, AST, and ALT levels were found during the ischemia and reperfusion periods compared with during the pre-ischemia period in all groups (p <0.05). The MDA, NO, AST, and ALT levels of rats that received ketamine increased less than did those of Group I (p <0.05). Significantly less injury was observed in the histopathological analysis of livers of rats administered ketamine (p <0.05). Conclusions: Ketamine showed a dose-dependent anti-inflammatory effect in I/R injury in the liver when administered after ischemia.
