Operative vaginal deliveries and their impact on maternal and neonatal outcomes - prospective analysis.

OBJECTIVE: Evaluation of maternal and neonatal outcomes in operative vaginal deliveries in prospective study analysis. DESIGN: Prospective case-control study analysis. SETTING: Prospective analysis of 292 operative vaginal deliveries (VEX, forceps) for the period June 2016 - August 2017 from overall 6056 vaginal deliveries. Type and frequency of maternal and neonatal trauma occurence was observed in connection with using vacuum-assisted delivery and forceps delivery, mainly the cephalohematomas and their complications. Collected data were statistically analysed. RESULTS: In the reported period from overall 6056 deliveries there were 216 vacuumextractions (3.6%) and 72 forceps deliveries (1.2%) performed. Both methods were used in four patients (VEX and forceps). The most frequent trauma in newborns were cephalohematomas. Remarkable cephalohematoma, requiring further observation has occured in 40 newborns (18.5%) after vacuum-assisted delivery and in 5 newborns (6.9%), (p = 0,017) after forceps delivery. Consequential punction of cephalohematoma occured only after vacuumextraction delivery and in 6 newborns (15.0 %). The third degree perineal rupture occured after vacuumextraction in 20 patients (9.3%) and after forceps delivery in 12 patients (16.7%), (p = 0,091). The fourth degree perineal rupture occured only after vacuumextraction and in 1 case (0.5%). CONCLUSION: The vacuumextraction compared with forceps is more likely to be associated with the statistically significant incidence of cephalohematomas and their further treatment. Forceps deliveries compared with vacuumextraction are more likely to be associated with the maternal perineal trauma, but the diference was not statistically significant.

Uterine rupture during pregnancy and delivery: risk factors, symptoms and maternal and neonatal outcomes - restrospective cohort.

OBJECTIVE: To analyze cases of uterine rupture during pregnancy and delivery. To report risk factors, maternal and neonatal outcomes. DESIGN: Restrospective cohort study. SETTING: Department of Obstetrics and Gynecology, Masaryk University, University Hospital Brno. METHODS: This study used data from medical records of 36 195 labours between 2011-2016 in the Department of Obstetrics and Gynecology Masaryk University Hospital Brno. We identified all cases of complete and incomplete uterine rupture diagnosed during pregnancy, delivery and puerperium. We analyzed risk factors, symptoms and signs and maternal and neonatal outcomes. RESULTS: We identified 15 uterine ruptures. Three cases occurred during pregnancy in absence of labour, ten cases in association with delivery, one case during puerperium and one case of uterine rupture was associated with induction of abortion in the 2nd trimester. Eight patients had a previous cesarean section. Other uterine surgery was reported in history of four cases, including myomectomy, perforation of uterine fundus during hysteroscopy, curretage. Three patients had unscarred uterus. Most of the cases presented with abnormal fetal heart rate tracing, abdominal pain, vaginal bleeding and hypotension. There were two perinatal deaths associated with uterine rupture and perinatal asphyxia was observed in five infants. No mother died in association with uterine rupture. Estimated blood loss higher than 1000 ml occurred in 11 cases. Three patients underwent hysterectomy. CONCLUSION: Overall prevalence of uterine rupture during pregnancy and delivery was 0,04%, in women with previous cesarean section was 0.2%, in women with unscarred uterus was 0.08. Suspicious fetal heart rate tracing and acute abdominal pain are the most common symptoms. Adverse neonatal outcomes were identified in seven cases.

[External cephalic version after 36th week of gestationAnalysis of women´s perspective]. / Zevní obrat plodu z polohy podélné koncem pánevním po 36. týdnu gravidity Analýza subjektivního hodnocení rodicek.

OBJECTIVE: Evaluation of opinions and subjective feelings of patients who have undergone an external cephalic version of a fetus in breech presentation after the 36th week of pregnancy. DESIGN: Observational analytic cohort study. SETTING: Department of Obstetrics and Gynecology, Masaryk University, University Hospital Brno. MATERIALS AND METHODS: We collected opinions and subjective evaluation from pregnant women who underwent an attempt of external cephalic version at the department of Gynecology and Obstetrics, Masaryk University in Brno in the period from 1st January 2015 to 31st December 2016 through a questionnaire. The questionnaire contained a total of 10 dichotomous, sampling, enumeration and scale questions. Questions were focused on the source and type of information on external cephalic version, expectations of the patients, evaluation of pain and feelings during the procedure and the overall impression. We also evaluated the differences between answers from patients after a successful and an unsuccessful version. RESULTS: In reported period 205 pregnant women underwent an attempt of external cephalic version. Procedure was successful in 105 (51.2%) cases of which 81 (77.1%) subsequently gave birth vaginally, 24 (22.9%) delivered by caesarean section, 10 (9.5%) out of all patients delivered in other hospitals. The total number of fully completed questionnaires was 187 (after a successful version 98 and 89 after an unsuccessful version). The most common source of information about the procedure was given to the patients from their gynecologists (40.5%) and doctors at the ambulance in the hospital where the patients are sent before delivery by their gynecologists (27.9%). Most mothers received mostly positive information (70.5%) - increased likelihood of vaginal delivery, high success rate, low risk to mother and child. Attitude of the gynecologists on the external cephalic version was positive in 52.6% and they recommended it. 14.4% of the patients had no fear before the procedure, 61% patients were nervous and 23% had fear. For 30.5% of the respondents was the version worse than expected. 33.7% of the patients expected that the procedure would be worse and for 35.8% of the women the procedure fulfilled their expectations. 42.2% of all patients rated the pain level on a scale from 0 (no pain) to 10 (maximum pain) in the range of 4-6 points, 28.9% evaluated the pain under 4 points and 28.9% over 6 points. Among other unpleasant feelings associated with external cephalic version were most frequently mentioned: nausea (15.9%), fear (39.8%), distress (7.5%). One-third of respondents, however, experienced no negative feelings (33.8%). 80.2% of the patients did not have any problems after the version. Out of all respondents 89.3% would undergo the procedure again and recommend it to others. Overall satisfaction rating on a scale from 0 (completely dissatisfied) to 5 (very satisfied) was 89.8% in the range from 4 to 5. When comparing the answers of patients after an external cephalic version there was no significant difference depending on the success of the version. CONCLUSION: The results show that the main source of information is given to the patients by their gynecologists and doctors in the hospital who recommend the procedure and significantly affect the attitude of patients towards external cephalic version. Fear and nervousness of the mothers is usually unfounded, most of the women evaluate the procedure positively and would recommend it to another pregnant women even in case of an unsuccessful attempt. Pain during the procedure is for most women bearable and in the overall ranking does not mean a significant problem.

[External cephalic version of breech fetus after 36 weeks of gestation - evaluation of efectiveness and complications]. / Obrat plodu zevními hmaty z polohy podélné koncem pánevním po 36. týdnu gravidity - hodnocení úspesnosti a komplikací.

OBJECTIVE: Evaluation of success rate and the safety of external cephalic version after 36 weeks of gestation. DESIGN: Retrospective analysis. SETTING: Department of Obstetrics and Gynecology, Masaryk University, University Hospital Brno. METHODS: A retrospective analysis of external cephalic version attempts performed on a group of 638 singleton breech pregnancies after 36 weeks gestation in the years 2003-2016 at the Department of Gynecology and Obstetrics, Masaryk University, Brno. The effectiveness, number and type of complications, mode of delivery and perinatal result were observed. RESULTS: The effectiveness of external cephalic version from breech to head presentation was 47.8% (305 cases). After a successful external cephalic version 238 patients (78.0%) gave birth vaginally. After unsuccessful cephalic version 130 patients (39.0%) gave birth vaginally. The number of serious complications did not exceed 0,9% and did not affect perinatal outcomes. External cephalic version-related emergency cesarean deliveries occurred in 6 cases (2 placental abruption, 4 abnormal cardiotocography). The fetal outcome was good in all these cases. The death of the fetus in connection with the external version has not occurred in our file. Spontaneous discharge of amniotic fluid within 24 hours after procedure occurred in 5 cases (0.8%). The spontaneous onset of labor within 24 hours of procedure occurred in 5 cases (0.8%). The pH value of a. umbilicalis < 7.00 occurred in 2 cases in the group with a successful external version and in the group with unsuccessful external version in 9 cases. The Apgar score in the 5th minute < 5 was both in the successful and unsuccessful group in 1 case. CONCLUSION: The external cephalic version of the fetus in the case of breech presentation after the 36th week of pregnancy is an effective and safe alternative for women who have a fear of the vaginal breech delivery. Performing the external cephalic version can reduce the rate of elective caesarean sections due to breech presentation at term.

[Current status and recommendations for intrapartum monitoring of fetal heart rate]. / Soucasné moznosti a doporucení pro intrapartální monitorování ozev plodu.

UNLABELLED: Monitoring of fetal heart rate is one of the basic components of obstetrical care, in which the cardiotocography remains the gold standard and screening method in early diagnosis of fetal hypoxia, even after introduction of other selective methods of intrauterine monitoring of fetal well-being. The review article is divided into several parts: pathophysiology of fetal oxygenation, fetal heart rate and changes of fetal hemodynamics, and rules for fetal heart rate auscultation. The main principles of cardiotocographic monitoring and evaluation of ante- and intrapartrum recordings according to the FIGO criteria from 1986 and evaluation of intrapartum recordings according to the 2015 FIGO recommendations are mentioned. At the end a comparative table of 1986 FIGO and 2015 FIGO criteria is presented. DESIGN: Review.

[Specific placental complications of monochorionic diamniotic twins born after 24 weeks of pregnancies - restrospective analysis]. / Specifické placentární komplikace u monochoriálních biamniálních dvojcat porozených po 24. týdnu gravidity - retrospektivní analýza.

OBJECTIVE: Purpose of this study was to determine the frequency of occurence of specific complications of monochorionic diamniotic twins born after 24 weeks of pregnancies and the effect of these complications on perinatal morbidity and mortality. TYPE OF STUDY: Restrospective analysis. SETTING: Dpt. of Obstetrics and Gynecology Masaryk University and University Hospital Brno. METHODOLOGY: A retrospective analysis of 175 monochorionic diamniotic pregnancies (mo-bi), which were terminated after the 24th week of pregnancy at the Department of Obstetrics and Gynecology Masaryk University and University Hospital Brno between the years 2008-2013. The specific complications such as twin-to-twin syndrome (TTTs), twin anemia polycytemia sequens (TAPS), selective intrauterine growth restriction (sIUGR), twin-arterial revers perfusion sequence (TRAP), single intrauterine fetal death (IUFD), placental insufficiency with both twins were identified using prenatal ultrasound examinations, perinatal results and the result of pathological anatomical examinations. Perinatal morbidity, neonatal mortality and neurological development were evaluated. The numbers of late detections of specific complications were observed. RESULTS: Specific complications in our group were identified in 50 pregnancies (28.6%). TTTs was diagnosed most often, by 18 pregnancies (10.3%), next most frequent diagnosis were sIUGR (9.7%) and TAPS (3.4%). The placental insufficiency with both twins complicated 2.6% pregnancies. 10 children had abnormal neurological development. Pregnancies with late detection had the worst perinatal results. No acute TTTs during delivery was detected. CONCLUSION: Specific placental complication reached 29.7% in our file. The most frequent complication was TTTs (10.3%) and selective growth restriction (9.7%). Pregnancies with late diagnosis of these complications had the worst results. The prenatal care by monochorial biamnial pregnancies should be at specialized centres from the 16th week of pregnancy every two weeks.

[The influence of breach position of the second twinon perinatal outcomes in vaginal births of bichorial - biamniotic twins after 33rd week of gravidity]. / Vliv naléhání druhého dvojcete koncem pánevním na perinatální výsledky pri vaginálním vedení porodu bichoriálních biamniálních dvojcat po 33. týdnu gravidity.

OBJECTIVE: The objective is to evaluate whether a breach presentation of the second twin has an influence on the perinatal results in vaginal births of bichorial-biamniotic twins after 33rd week of pregnancy. DESIGN: Retrospective analysis. SETTING: Department of Obstetrics and Gynecology, Masaryk University and University Hospital Brno. SAMPLE AND METHODS: The current study is a retrospective analysis of 695 vaginal births of bichorial-biamniotic twins after 33rd week of pregnancy. All births were conducted at the Department of Obstetrics and Gynecology, Masaryk University and University Hospital Brno during the span of 2004-2013. The sample was divided into2 groups. Group A consisted of 550 births of both twins in vertex presentation, group B consisted of 145 births in which the second twin happened to be in the breach presentation. The factors that have been evaluated include the percentage of births finished vaginally, perinatal results (pH a. umbilicalis below 7.0 and Apgar score in the 5th minute below 5) and early neonatal mortality and morbidity. Data from both groups have been compared with the use of Fishers exact test. RESULTS: For the group A, 81.3% of births were finished vaginally, as opposed to 85.5% in group B. Acute Caesarean sections conducted on the second twin consisted 4% (22 cases) in group A and 3.4% (5 cases) in group B. No significant difference has been found between the two groups in both perinatal results (p = 0.6 for pH from a. umbilicalis below 7.0 and p = 0.7 for Apgar score in the 5th minute below 5; both two-tailed) and in the frequency of early neonatal mortality and morbidity. In total,5 neonatal deaths have occured in 28 days after birth, out of which 2 have occured in group A and 3 in group B. CONCLUSION: It was concluded that breach presentation of the second twin does not influence perinatal results in vaginal births of bichorial-biamniotic twins. KEYWORDS: bichorial-biamniotic twins, vaginal birth, breach presentation, perinatal mortality, perinatal morbidity.

[Vaginal breech delivery after 36 week of pregnancy in a selected group of pregnancy - analysis of perinatal results in years 2008-2011]. / Vaginální vedení porodu koncem pánevním po ukonceném 36. týdnu gravidity u selektované skupiny tehotenství - analýza perinatálních výsledku let 2008-2011.

OBJECTIVE: To determine intrapartum mortality, neonatal mortality and serious neonatal morbidity in selected group of planed vaginal breech deliveries after 36 week of pregnancy. Compare vaginal breech deliveries with primary cesarean deliveries.Designe: Retrospective study. SETTINGS: Department of Obstetrics and Gynaecology, Masaryk University, University Hospital Brno; Department of neonatology, University Hospital Brno; Faculty of Economics and Management, University of Defence in Brno. METHODS: Retrospective analysis of 1013 births of singleton pregnancies with breech position of the fetus after 36 completed week of pregnancy at University Hospital Brno in the years 2008-2011. Vaginal delivery was planed for 430 women (42.4%). Elective caesarean section was performed in 583 women (57.6%). An assessment of intrapartum and neonatal mortality and serious neonatal morbidity and incidence of umbilical artery pH < 7.00. We also evaluated non-serious neonatal morbidity. RESULTS in the group of vaginal breech deliveries, including births completed by acute caesarean section, were compared with results in the group of elective caesarean sections. RESULTS: In the group of 430 women with planned vaginal breech delivery, 347 delivered vaginally (80.7%), by acute caesarean section 83 women (19.3%). In the group of planned vaginal births, including births completed by acute caesarean section, pH < 7.00 in umbilical artery occurred in 9 cases (2.1%). In the group of elective caesarean deliveries pH < 7.00 does not occurred. Death of the fetus during labor or before 28 day after birth does not occurred. A statistically significant difference in the incidence of serious neonatal morbidity between the group of planned vaginal births and births by elective caesarean section was found in Apgar score in 5th minute < 5 (2 versus 0), peripheral nerve injury persisting at discharge (2 versus 0) and admission to the neonatal intensive care unit for longer than 24 hours (2 versus 10). When comparing all cases of serious neonatal morbidity between the two groups, the difference was not statistically significant (1.2% versus 1.9%, NS). CONCLUSION: When strict criteria are met during selection of women appropriate for vaginal breech delivery and during labor, planned vaginal breech delivery at term is save option. The incidence of severe neonatal morbidity when compared with elective caesarean section is not increased. KEYWORDS: breech presentation, vaginal delivery, caesarean section, neonatal morbidity, neonatal mortality.

[Incarcerated uterus in pregnancy - pitfalls of diagnosis, clinical course and therapy: two case reports]. / Inkarcerace delohy v gravidite - úskalí diagnostiky, klinického prubehu a terapie: dve kazuistiky.

OBJECTIVE: Analysis of two cases of incarcerated uterus during pregnancy. DESIGN: Two case reports. SETTING: Department of Gynecology and Obstetrics, Masaryk University, University Hospital Brno. METHODS AND RESULTS: In two cases of incarcerated uterus, which were resolved on Department of Gynaecology and Obstetrics, University Hospital Brno is shown a different clinical course, leading to the detection and solutions at different gestational weeks. The first case was detected in 31st week of pregnancy and was characterized by nearly asymptomatic course in a pregnant woman with a scar in the lower uterine segment after a previous caesarean section. The delivery was scheduled for the end of the 36th week of pregnancy by iterative caesarean section. The second case was detected on the 27th week of pregnancy due to significant subjective difficulties of pregnant woman that impressed as acute event of abdomen. Despite all attempts at conservative therapy was necessary to terminate the pregnancy by caesarean section at 28 week of pregnancy due to the high risk of uterine rupture. CONCLUSION: Incarcerated uterus is a rare complication of pregnancy. Diagnostics complains varied clinical picture of the nonspecific subjective difficulties. Missed diagnosis can lead to a number of serious obstetric complications. In case of failure of conservative therapy and progression of difficulties is necessary to think about the real risk of uterine rupture. Before performing a caesarean section is essential knowledge of the mutual position of the lower uterine segment, urinary bladder and cervix.

[Vaginal birth after previous caesarian section--outcomes analysis 2007-2010]. / Vedení porodu po predchozím císarském rezu, analýza výsledku z let 2007-2010.

OBJECTIVE: Analysis of births after previous caesarean section (SC) at Department of Obstetrics and Gynaecology, Masaryk University, Brno. Determination of successful vaginal deliveries after previous SC (complete vaginal birth) and the factors that influence success. Risk identification and determination of the frequency of complications. Comparison of vaginal births after previous SC (VBAC) with elective repeat caesarean section (ERCS). MATERIALS AND METHODS: Retrospective analysis of 24,342 births, which were conducted in 2007-2010 at Department of Obstetrics and Gynaecology, Masaryk University, Brno. For the reporting period a total of 1391 pregnant women with a history of caesarean section gave birth (100.0%). The distribution of births after previous caesarean section into 2 groups according to a method of delivery. Trying to line vaginal birth (VBAC) with 986 mothers (70.9%). Elective repeat caesarean section (ERCS) was performed in 405 mothers (29.1%). Analysis and comparison of results in both groups. RESULTS: The overall success of VBAC (complete vaginal births after previous SC) in our group reached 80.8%. When evaluating the success of the subgroups was the strongest positive predictive factor the onset of spontaneous contractile activity (89.5% success rate) and vaginal delivery in history (88.2% success rate). The most significant negative predictive factor was a history of previous caesarean birth because of failure mechanism of birth (success rate 72.0%). The most common complication in both groups VBAC and ERCS group was blood loss (5.1% versus 2.0%, p = 0.045). Detection of dehiscence at the previous uterotomy (0.4% versus 0.5%, NS). In our group has been reported no case of uterine rupture. The frequency of postpartum hysterectomy was comparable in both groups (0.3% versus 0.5%, NS). In both groups, VBAC and ERCS was reported one case of bladder lesion, as surgical complications during the acute or planned caesarean section. No maternal or fetal death in relation to birth in our cohort occurred. CONCLUSION: Vaginal birth after previous caesarean section is a safe way of delivery in selected groups of mothers. An essential requirement is careful monitoring during labor to the exclusion of excessive uterine activity and protracted labor.

[Role of ST-analysis of fetal ECG in intrapartal fetus monitoring with presumed growth retardation]. / Význam ST-analýzy fetálního EKG pri intrapartálním monitorování plodu s predpokládanou rustovou retardací.

OBJECTIVE: Evaluation of the role of ST analysis of fetus ECG for early detection of developing acute hypoxia in the course of delivery of fetuses with presumed growth retardation. A comparison with present way of intrapartal fetus monitoring. Impact on the number of surgical births for indications of threatening fetus hypoxia. Influence of the method on perinatal results and postnatal adaptation of the newborns. TYPE OF STUDY: A prospective study. SETTING: Gynecology-Obstetrics Clinic, Masaryk University and Teaching Hospital Brno. METHOD: Forty seven women with a growth retardation of the fetus diagnosed before delivery who gave birth in the Teaching Hospital in Brno during 2003-2005 and intrapartal ST analysis of fetus ECG was subsequently used, were enrolled into this prospective study (group A). The control group consisted of 87 deliveries taking place in the same period of time and concerning women with fetuses suffering from growth retardation and monitored by standard methods (group B). The standard methods included cardiotocography (CTG), supplemented with pulse oximetry (IFPO) if needed. The diagnosis of intrauterine fetus growth retardation was established on the basis of the results of repeated prepartal ultrasound fetus biometry with estimation of the mass, which corresponded to a group below 10 percentile for the given gestational age. The numbers of vaginal deliveries and surgically treated delivery due to threatening fetus hypoxia (Cesarean section, forceps delivery) were recorded. The authors evaluated postpartal pH from umbilical artery, independently for the group of values of pH < 7.00, the group of pH 7.00-0.10 and pH 7.10 or more. The values of Apgar score were evaluated for the first, fifth and tenth minute, respectively. The neonatologist followed the duration of stay of the newborn at the Newborn Intensive Care Unit, the Intermediate Care Unit, total duration of hospitalization, the occurrence of sepsis in the early newbotn period, the occurrence of hyperbilirubinemia, and the conclusion of neurological examination. All the results were evaluated statistically by the chi2 test, Kruskal-Wallis test or the Anova method. RESULTS: There was no statistically significantly difference in the number of delivery ended by surgery for threatening fetus hypoxia (p = 0.856) or the detection rate of intrapartal hypoxia according to pH values of umbilical blood divided into the three groups (p = 0.657, p = 0.958, p = 0.730, respectively). The values of Apgar score differed in favor of the group A significantly only in the first minute at the level of 5% opf significance (p = 0.018). The values of Apgar score in the fifth and tenth minute did not show any significant difference (P = 0301 and p = 0313, respectively). There was no statistically significant difference in neonatological results between the group A and B. CONCLUSION: The use of ST analysis of fetal ECG in the course of delivery of fetuses with presumed intrauterine growth retardation did not show any significant difference from the presently used methods (CTG supplemented with IFPO if needed). In using the method there was not any effect on the number of surgically treated deliveries for indications of threatening acute fetus hypoxia or perinatal results and postnatal adaptation of the newborns.

[ST analysis of fetal ECG in premature deliveries during 30th-36th week of pregnancy]. / ST analýza fetálního EKG u predcasných porodu ve 30.-36. týdnu tehotenství.

OBJECTIVE: To determine the possibilities of ST analysis of fetal ECG (STAN) in premature deliveries between 30th to 36th week of pregnancy. To compare the results of a group of premature deliveries monitored by ST analysis with a control group of premature deliveries monitored by means of cardiotocography (CTG) and intrapartum fetal pulse oxymetry (IFPO). TYPE OF STUDY: A prospective study. SETTING: Department of Gynecology-Obstetrics, Masaryk University and Faculty Hospital Brno. METHODS: The authors evaluated 39 women with premature delivery between 30th and 36th week of pregnancy from a total cohort of 239 high-risk pregnant women, who had been monitored by means of ST analysis of fetal ECG. The control group included 229 pregnant women who gave birth between 30th and 36th week of pregnancy under the monitoring with CTG and IFPO. The allocation into individual groups was at random order. The authors evaluated the duration and way of termination of delivery, pH in arterial umbilical blood, Apgar score in the first, fifth and tenth minute, total duration of hospitalization, necessity and duration of stay at the Neonatologic Intensive Care Unit, Intermediatry Intensive Care Unit, the presence of sepsis, hyperbilirubinemia and neurological state of the newborn. The statistical analysis was performed by means of the Fisher's exact test, Kruskal-Wallis test, chi2 test and the parametric test Anova. RESULTS: Almost none of the observed parameters in both categories of premature deliveries (STAN vs. CTG+IFPO) exhibited a statistically significant difference except a mild neurological affection of the newborn. In the group of premature deliveries monitored by ST analysis there are only 33.3% of newborns with signs of light neurological damage as compared with the control group, where 56.3% subjects were so affected (p<0.01). CONCLUSION: It has become obvious that the ST analysis of fetal ECG in premature deliveries between 30th and 36th week of pregnancy provides the same results as the so far used monitoring by CTG and IFPO. In the group of premature deliveries monitored by the ST analysis, there were significantly less frequent neurological disturbances.
