Is There Still a Place for Forceps Delivery in Modern Obstetrics?

BACKGROUND: Nowadays, we are witnessing a decrease of vaginal instrumental deliveries and continuous increase of caesarean section rate. However, proper identification of possibility of execution, indications for instrumental delivery and their skilful use may improve the broadly understood maternal and neonatal outcomes. The aim of this study is to present prevalence, risk factors, indications and outcomes of forceps deliveries among the patients at Department of Perinatology, Lodz. MATERIAL AND METHODS: A retrospective study was conducted at the Department of Perinatology, Medical University of Lodz. The study included forceps deliveries carried out between January 2019 and December 2022. Total number of 147 cases were analysed in terms of indications for forceps delivery and maternal and neonatal outcomes such as vaginal - or cervical - laceration, postpartum haemorrhage, perineal tear, newborn injuries, Apgar score, umbilical cord blood gas analysis, NICU admission and cranial ultrasound scans. RESULTS: The prevalence of forceps delivery was 2.2%. The most common indication for forceps delivery was foetal distress (81.6%). Among mothers, the most frequent complication was vaginal laceration (40.1%). Third-and fourth-degree perineal tears were not noted. Regarding neonatal outcomes, Apgar score ≥ 8 after 1st and 5th minute of life received accordingly 91.2% and 98% of newborns. Only 8.8% experienced severe birth injuries (subperiosteal haematoma, clavicle fracture). CONCLUSIONS: Although foetal distress is the most common indication for forceps delivery, the vast majority of newborns were born in good condition and did not require admission to NICU. Taking into consideration high efficacy and low risk of neonatal and maternal complications, forceps should remain in modern obstetrics.

Serum S100B Protein Concentrations in SGA/FGR newborns.

OBJECTIVES: Fetal growth restriction is associated with chronic fetal hypoxia, poor perinatal outcome and increased perinatal mortality. There are no reliable methods to detect cell damage in the central nervous system (CNS) in these patients. The findings of increased an acidic calcium-binding protein (S100B) concentration in biological fluids of infants after brain injury have supported the use of S100B as a biochemical marker of CNS damage. The purpose of the study was to assess blood S100B concentrations in small for gestational age (SGA) and appropriate for gestational age (AGA) newborns and to evaluate the usefulness of S100B for early detection of hypoxia. MATERIAL AND METHODS: The investigation was carried out between November 2011 and April 2014. Serum S100B protein level was assessed in cord blood collected from newborns after birth. Medical records of mothers of neonates studied were reviewed for pregnancy induced hypertension (PIH), preeclampsia, maternal smoking during pregnancy and abnormalities in umbilical artery (UA) Doppler ultrasound examination. RESULTS: The study was carried out in 88 SGA neonates and 80 AGA neonates. The median value of S100B protein concentration in the SGA study group was significantly higher than in AGA controls (p < 0.001). Cord blood serum S100B concentration in SGA neonates with prenatal normal UA Doppler ultrasound findings (n = 32) did not differ from that SGA neonates with abnormal prenatal UA Doppler findings (n = 25) (p = 0.74), but was significantly higher than in AGA newborns (p < 0.001). CONCLUSIONS: Elevated S100B protein levels in cord blood collected from SGA newborns may be helpful in detecting infants at higher risk of postnatal neurologic disturbances at an early stage.

Therapeutic hypothermia in asphyxiated newborns: selective head cooling vs. whole body cooling - comparison of short term outcomes.

OBJECTIVES: Therapeutic hypothermia TH became broadly used in the management of the asphyxiated newborns. Although two cooling methods are used, so far the superiority of none of them has been established. The purpose of the study is to compare two cooling methods: selective head cooling (SHC) and whole body cooling (WBC) MATERIAL AND METHODS: We conducted a prospective observational study in newborns with HIE. The patients received one of methods: SHC or WBC. The eligibility criteria were similar to previous studies. Stability of cardio-respiratory parameters and short term outcomes were analyzed. RESULTS: 78 neonates with hypoxic-ischemic encephalopathy due to perinatal asphyxia were involved in this study. The SHC group consisted of 51 newborns, the WBC group consisted of 27 patients. Both study groups had similar baseline characteristics and condition at birth. There were no significant differences in hospital course, neurological status and adverse effects associated with cooling procedure between groups. Analyzing the rate of thrombocytopenia and the number of transfusions of blood components no statistically significant differences were found between the groups. CONCLUSIONS: Results of our study indicate that two compared methods of TH despite varied target core temperature ranges do not differ significantly according to clinical course and risk of adverse events. Further observations are conducted and we look forward to the results of the long neurodevelopmental care.

Bronchopulmonary dysplasia in very and extremely low birth weight infants - analysis of selected risk factors.

AIM: The aim of the study was to analyze the role of specific risk factors affecting the development and clinical course of BPD in infants born before 32 weeks of gestation with a birth weight ≤ 1500g. MATERIALS AND METHODS: The study included 222 infants born and hospitalized at the Department of Neonatology, Polish Mother's Memorial Hospital-Research Institute. At their 28-th day of life, the patients were divided into two groups: with and without BPD. The grade of BPD severity was determined at 36 weeks of postmenstrual age. RESULTS: BPD was diagnosed in 117 (52.7%) of infants, 65 (55,6%) of them developed its mild, 29 (24,8%) moderate and 23 (19,7%) severe form. Infants with BPD had significantly lower gestational age than those without BPD: 27.0 weeks (IQR 26.0-28.3 weeks) vs. 30.0 weeks (IQR 29.3-31.0 weeks), and lower birth weight: 900g (IQR 740.0-1050.0g) vs. 1290g (IQR 1100.0-1370.0g). A significantly lower gestational age R=-0.70, p < 0.0001 and birth weight R=-0.66, p<0.0001 were observed in correspondence with the increase of BPD severity. In BPD group there were 72 (61.5%) male infants, whereas in that without BPD 54 (51.4%) of them, p=0.1290. In the group with mild form of BPD, there were 29 (44.6%) males, with moderate 23 (79.3%) and severe 20 (87.0%), p=0.0002. A statistically significant difference was found for: respiratory distress syndrome 116 (99.2%) vs. 83 (79.1%), p<0.0001, congenital infection 70 (59.8%) vs. 40 (38.1%), p=0.0012, patent ductus arteriosus 61 (52.1) vs. 28 (26.7), p=0.0001, complete prenatal steroid therapy 77 (65.8%) vs. 85 (81.0%), p=0.0112 and Apgar score of 1 min., p<0.0001 and 5 min., p<0.0001. In the group with BPD significantly more frequent were: intraventricular hemorrhage 87 (74.4%) vs. 37 (35.2%), p<0.0001, periventricular leukomalacia 11 (9.4%) vs. 0 (0.0%) p=0.0009 and retinopathy of prematurity 47 (40.2%) vs. 6 (5.7%), p<0.0001. No statistical significance was found for: premature rupture of membranes, the route of delivery, Ureaplasma spp. infection and necrotizing enterocolitis. Independent factors affecting the risk of BPD are: gestational age (OR 0.3213, p<0.0001), birth weight (OR 0.9968, p=0.0036), and respiratory distress syndrome (OR 3.9388; p=0.0142). CONCLUSIONS: Lower gestational age, low birth weight, respiratory distress syndrome, Apgar score, congenital infection, lack of prenatal steroid therapy, patent ductus arteriosus and male gender are the risk factors for the development of BPD.

Difficulties in prenatal diagnosis of tumour in the fetal sacrococcygeal area.

Prenatal ultrasound at the 20th week of gestation revealed a 3-cm tumour in the sacrococcygeal area. Initially, a sacrococcygeal teratoma was suspected on the basis of fetal ultrasonography, which revealed normal heart anatomy and an increasing tumour mass. The diagnosis was then changed to fetus in fetu or teratoma. Prenatal magnetic resonance imaging at the 34th week of pregnancy confirmed the ultrasound diagnosis. No other anomalies were found. Elective caesarean section was performed at term. The care team included a paediatric surgeon, obstetricians, neonatologists, midwives, and an anesthesiologist. A female newborn was delivered in good condition. The tumour was resected in the operating room and mature teratoma was established by histopathological evaluation. Surprisingly, agenesis of the right forearm was revealed which had not been detected prenatally, despite many examinations (both in our hospital and earlier at a primary care obstetrician office).

Nutritional therapy in paediatric intensive care units: a consensus statement of the Section of Paediatric Anaesthesia and Intensive Therapy the Polish Society of Anaesthesiology and Intensive Therapy, Polish Society of Neonatology and Polish Society for.

Providing nutritional therapy via the gastrointestinal tract in patients in paediatric intensive care units (PICUs) is an effective method for delivering energy and other nutrients. In the event of contraindications to using this method, it is necessary to commence parenteral nutrition. In the present study, methods for nutritional treatments in critically ill children are presented, depending on the clinical situation.

[The first application of therapeutic hypothermia in Poland--selective head cooling (Cool-Cap) with whole-body moderate hypothermia in a newborn with features of hypoxic ischemic encephalopathy]. / Pierwsze zastosowanie hipotermii leczniczej w Polsce--selektywne chlodzenie glowy (Cool-Cap) z umiarkowana hipotermia ciala u noworodka z cechami encefalopatii niedokrwienno-niedotlenieniowej.

The authors present the first application of therapeutic hypothermia in a newborn in Poland. The female newborn, born with severe asphyxia, was transported to a referral perinatal center where the method of brain cooling was possible. Severe hypoxic ischemic encephalopathy was confirmed by an integrated EEG. During the cooling procedure (which lasted 72 hours), no important side effects were noticed. The neurodevelopmental outcome of the baby assessed during the first 2 years of her life is normal.

[Can we expect decreasing the incidence of patent ductus arteriosus (PDA) in the population of premature neonates who had received antenatal steroid therapy?]. / Czy u wczesniaków poddanych prenatalnej steroidoterapii mozna spodziewac sie ograniczenia czestosci wystepowania przetrwalego przewodu tetniczego (PDA)?

OBJECTIVES: The efficacy of antenatal steroid therapy (ANS--use with the recommendation from 1999; therapy repeated every 7-10 days; dexamethasone was used) on the incidence of RDS in neonates born before 34 weeks of gestation has been well documented in several studies. However, we know very little about the influence of ANS on patent ductus arteriosus (PDA). DESIGN: The purpose of this study was to assess the influence of ANS on the incidence of PDA in neonates born before 35 weeks of gestation. MATERIALS AND METHODS: The analysed population consisted of 425 newborns delivered at Research Institute Polish Mother's Memorial Hospital between 1996-1998. Patients were enrolled in three groups according to mode of ANS: Group I--complete ANS; Group II--partial ANS; Group III--without ANS (reference group, OR = 1). The complete ANS consisted of at least 24 mg of dexamethasone with a first dose given not earlier then 24 hours before delivery. The analysis was based on retrospective evaluation of patient's medical records. PDA was diagnosed during echocardiographic examination or during autopsy. The incidence and risk of significant PDA in enrolled groups were estimated. RESULTS: Use of complete ANS has no influence of the incidence of PDA. In the partial ANS group the risk of PDA (OR 1,89; p = 0,052 vs group III) was increased. Risk of PDA was also higher in patients born before 29 weeks of gestation, especially from the partial ANS group. CONCLUSIONS: The antenatal steroid therapy has influence of the incidence of PDA. We observed higher risk of PDA in the group of neonates born before 29 weeks of gestation and in the partial ANS group.

[Influence of antenatal steroid therapy on newborn nervous system]. / Wplyw steroidoterapii prenatalnej na stan ukladu nerwowego noworodka.

OBJECTIVES: Analysis of the impact of prenatal glucocorticoids on the neurological outcome of a newborn. DESIGN: The authors reviewed the most current reports concerning the influence of antenatal steroid therapy (used to accelerate of fetal lung maturation) on neonates. In the study we discussed the influence of steroid therapy on growth and development of the brain, as well as the occurrence rate of the most common neurological abnormalities, such as: intraventricular haemorrhage and periventricular leukomalacia. MATERIALS AND METHODS: Recent literature review. RESULTS: We believe that use of antenatal corticosteroids remains a major factor in reducing neonatal mortality. Treatment with one course of betamethasone, as we know at the present time, is completely safe for a newborn's nervous system. Many courses of antenatal steroids may decrease fetal brain growth. Antenatal steroid therapy reduced the incidence of intraventricular haemorrhage in preterm infants. Use of betamethasone, but probably not dexamethasone, in antenatal therapy reduced the incidence of periventricular leukomalacia in extremely low weight infants. CONCLUSIONS: According to recent studies regarding probable unfavourable role of dexamethasone in neonatal neurological development we are of opinion that dexamethasone should be replaced by betamethasone in therapy of imminent preterm labour.
