Introduction. The use of epidural anaesthesia in delivery with the purpose to reduce pain and fear in a pregnant woman has the influence on the physiological status of the woman in childbirth and the course of delivery. From the epidural space of the pregnant woman, one part of free anaesthetic comes in the foetal circulation through the mother's circulation and placenta and connects with the foetal proteins. A lower value of albumins and serum proteins in the foetal circulation give bigger free fraction of anaesthetic which is accumulated in the foetal liver, brain and heart full of blood. Objective. The aim of the study was to examine the influence of epidural anaesthesia on the newborn. Methods. Retrospective study of 6,398 documents of newborns was performed in our Clinic of Gynaecology and Obstetrics 'Narodni front' during 2006. The first group was made of 455 newborns from deliveries with epidural anaesthesia and the second was the control group of 5,943 remaining newborns. In both groups we analysed the following: sex, week of gestation, weight, Apgar score, measure of care and resuscitation, perinatal morbidity and then the obtained results were compared. Results. Most of deliveries were vaginal without obstetric intervention (86.6%). The number of deliveries finished with vacuum extractor (4.6%) was statistically significantly bigger in the group with epidural anaesthesia than in the control group. Most of the newborns in the first group were born on time (96.5%) in 39.0?1.0 week of gestation and with foetal weight 3448?412 grammes. There was no statistical significance in Apgar score between both groups. Epidural anaesthesia does not increase the degree of the newborn's injury. Lower pH of blood was found in the newborns from deliveries with vacuum extractor or operated on (the Ceasarean section). Conclusion. Application of epidural anaesthesia decreases duration of delivery and has no adverse effects on the newborn and hypoxic encephalopathy is lower.

Abstract Background Instrumental deliveries are an unavoidable part of obstetric practice. Dedicated training is needed for each instrument. To identify when a trainee resident can be entrusted with instrumental deliveries by Suzor forceps by studying obstetric anal sphincter injuries. Methods A French retrospective observational study of obstetric anal sphincter injuries due to Suzor forceps deliveries performed by trainee residents was conducted from November 2008 to November 2016 at Limoges University Hospital. Perineal lesion risk factors were studied. Sequential use of a vacuum extractor and then forceps was also analyzed. Results Twenty-one residents performed 1530 instrumental deliveries, which included 1164 (76.1%) using forceps and 89 (5.8%) with sequential use of a vacuum extractor and then forceps. Third and fourth degree perineal tears were diagnosed in 82 patients (6.5%). Residents caused fewer obstetric anal sphincter injuries after 23.82 (+/− 0.8) deliveries by forceps (p = 0.0041), or after 2.36 (+/− 0.7) semesters of obstetrical experience (p = 0.0007). No obese patient (body mass index> 30) presented obstetric anal sphincter injuries (p = 0.0013). There were significantly fewer obstetric anal sphincter injuries after performance of episiotomy (p <  0.0001), and more lesions in the case of the occipito-sacral position (p = 0.028). Analysis of sequential instrumentation did not find any additional associated risk. Conclusion Training in the use of Suzor forceps requires extended mentoring in order to reduce obstetric anal sphincter injuries. A stable level of competence was found after the execution of at least 24 forceps deliveries or after 3 semesters (18 months) of obstetrical experience.
