RESUMEN
Importance: Establishing stable breathing is a key event for preterm infants after birth. Delivery of pressure-stable continuous positive airway pressure and avoiding face mask use could be of importance in the delivery room. Objective: To determine whether using a new respiratory support system with low imposed work of breathing and short binasal prongs decreases delivery room intubations or death compared with a standard T-piece system with a face mask. Design, Setting, and Participants: In this unblinded randomized clinical trial, mothers threatening preterm delivery before week 28 of gestation were screened. A total of 365 mothers were enrolled, and 250 infants were randomized before birth and 246 liveborn infants were treated. The trial was conducted in 7 neonatal intensive care units in 5 European countries from March 2016 to May 2020. The follow-up period was 72 hours after intervention. Interventions: Infants were randomized to either the new respiratory support system with short binasal prongs (n = 124 infants) or the standard T-piece system with face mask (n = 122 infants). The intervention was providing continuous positive airway pressure for 10 to 30 minutes and positive pressure ventilation, if needed, with the randomized system. Main Outcomes and Measures: The primary outcome was delivery room intubation or death within 30 minutes of birth. Secondary outcomes included respiratory and safety variables. Results: Of 246 liveborn infants treated, the mean (SD) gestational age was 25.9 (1.3) weeks, and 127 (51.6%) were female. A total of 41 infants (33.1%) receiving the new respiratory support system were intubated or died in the delivery room compared with 55 infants (45.1%) receiving standard care. The adjusted odds ratio was statistically significant after adjusting for stratification variables (adjusted odds ratio, 0.53; 95% CI, 0.30-0.94; P = .03). No significant differences were seen in secondary outcomes or safety variables. Conclusions and Relevance: In this study, using the new respiratory support system reduced delivery room intubation in extremely preterm infants. Stabilizing preterm infants with a system that has low imposed work of breathing and binasal prongs as interface is safe and feasible. Trial Registration: ClinicalTrials.gov Identifier: NCT02563717.

BACKGROUND: Women's attitudes towards obstetric forceps likely contribute to declining use and opportunities for residency training, but formal documentation of women's attitudes towards obstetric forceps is currently limited. A clearer understanding should help guide our attempts to preserve its use in modern obstetrics and to improve residency training. Our objective is to document women's attitudes towards obstetric forceps and the influence basic demographic variables have on those attitudes. METHODS: A cross sectional study was performed. We developed a one-time anonymous structured 5-question survey that was given to all women with low-risk pregnancies presenting to our medical center for prenatal care between October 2018-December 2018. The questionnaire asked for the woman's self-reported age, race, education level and insurance type. The five questions were as follows: (1) Do you think forceps should be used to deliver babies, (2) Is forceps safe for the baby, (3) Is forceps safe for the mother, (4) Do you think forceps can help to lower the cesarean section rate, (5) Do you think physicians in training should learn to place forceps on a real patient. We calculated means and proportions for the responses according to the overall group and various subgroups. Statistical analysis included Kruskall-Wallis or Mann-Whitney tests as appropriate. Results were also adjusted by regression using a Generalized Linear Model. Power calculation showed sample size of 384 was required. RESULTS: A total of 499 women returned the questionnaire. Response rate was 56.8% (499/878). The findings suggest that women's perceptions towards forceps are generally negative. Women with white ethnicity, college education or higher and private insurance did have more favorable views than their counterparts, but the majority still had unfavorable views. Age was not shown to have a significant effect on maternal attitude. CONCLUSION: Women's views towards forceps use in the University of Kansas Medical Center are negative and may be contributing to the decline of its use. Improving women's perceptions of forceps would require multiple different strategies rather than a single focused easily-implemented message. If forceps training continues, such training will rely on a minority of women who will accept forceps use in childbirth.

INTRODUCTION: Women undergoing instrumental delivery are known to be at higher risk of urinary retention, which can lead to long-term complications such as voiding dysfunction. Nulliparous women undergo a pronounced and sudden change in the perineum due to stretching during delivery, which may add to the perineal trauma from an episiotomy, increasing the risk of urinary retention. We aim to study the incidence and risk factors associated with postpartum urinary retention in women undergoing instrumental delivery. MATERIAL AND METHODS: Pregnant women who had an instrumental delivery after 37 weeks of gestation at JIPMER, Puducherry, India, between January 2017 and June 2017 were included in the study. Postpartum urinary retention was defined as the inability to void spontaneously or ultrasonographic documentation of post-void residual volume of >150 mL, 6 hours after delivery. Demographic factors, clinical profile and follow-up of these patients were noted. Multivariate logistic regression analysis was performed to assess the risk factors associated with urinary retention and was presented as adjusted odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Postpartum urinary retention was noted in 124 (20.6%) women undergoing instrumental delivery. Overt and covert urinary retention occurred in 2.3% and 18.3%, respectively. After adjusting for other risk factors, nulliparity (adjusted OR = 4.05, 95% CI 2.02-8.12 compared with multiparity) and prolonged second stage (OR = 3.96, 95% CI 1.53-10.25) compared with suspected fetal compromise as an indication for instrumental delivery was associated with increased risk of postpartum urinary retention. Interaction was noted between parity and episiotomy on the occurrence of postpartum urinary retention (P = .010). Among nulliparous women, those with episiotomy (adjusted OR = 6.10, 95% CI 2.65-14.04) have higher odds of developing postpartum urinary retention compared with those without episiotomy. CONCLUSIONS: Approximately one of five (20.6%) women undergoing instrumental delivery developed postpartum urinary retention. Among women undergoing instrumental delivery, episiotomy increased the chances of developing postpartum retention in nulliparous but not multiparous women. Prolonged second stage as an indication for instrumental delivery also increased the chances of retention. Future studies are needed to define the cutoff for diagnosis and to evaluate the long-term effects of covert postpartum urinary retention, as well to study the effect of episiotomy on development of postpartum urinary retention in women undergoing instrumental delivery.

BACKGROUND: Manual perineal protection (MPP) is an intrapartum intervention suggested to protect perineal integrity during childbirth. Proper execution of MPP is complex and evaluation of its true contribution is difficult in the clinical setting because of the large number of obstetric variables, some of which are hardly quantifiable. In this study we aimed to gather initial data on the forces executed by the accoucheur's thumb, index and middle fingers during MPP at the time of fetal head expulsion, quantify the duration of the intervention and investigate the timely interaction of the different components of MPP. METHODS: Two bespoke right-handed measurement gloves (MG), with built in sensors, were designed and produced. The MG allowed the electronic real-time measurement of applied forces during MPP and transferred this data wirelessly to an integrated computer system. Sterile gloves were worn over the MG when used at the time of birth. The study was undertaken between January and December 2019. Singleton, term pregnant women having their first vaginal birth who provided a valid written consent were enrolled into this prospective pilot study. All deliveries were undertaken by one of two obstetricians experienced in MPP. RESULTS: Twenty women were enrolled. The mean duration of execution of MPP during the last contraction was 13.6 s. In 20% it lasted < 5 s. The overall mean values of the average and maximum forces of the thumb, index and middle fingers were 26.7 N; 25.5 N; 20.2 N and 34.3 N; 32.6 N; and 27.6 N respectively. The onset of fingers and thumb activity was simultaneous in 13 cases (65%), while in seven (35%) deliveries the middle finger's force activity was initiated later. CONCLUSIONS: MPP during fetal head expulsion happens over a short period of time. In the majority of cases the thumb and fingers actions started simultaneously. There were differences in the duration of application and the forces executed by the fingers and thumb between the two practitioners, however this was only significant for thumb measurements. The results obtained will aid in improving further MPP modeling studies to optimize the technique.

OBJECTIVE: Our aim was to describe risk factors associated with 34DPT in operative and non-operative vaginal deliveries, over a five-year period. STUDY DESIGN: This was a retrospective cohort study including 39,227 vaginal deliveries from 2013 to 2017 in a single French University Hospital. Annual characteristics of the analyzed population were recorded. Univariate logistic regression was used to evaluate the association between these characteristics and 34DPT. Multivariate analysis was used to identify combinations of risk factors associated with instrumental delivery. RESULTS: The rate of perineal tears was constantly rising but rate of 34DPT was stable, ranging between 0.8 and 1.4% over the study period. Cesarean section rate was stable between 18.8% and 19.6%. Rate of diabetes, preeclampsia and obesity (BMI < 40) was increasing and episiotomy rate decreasing (from 19.8% to 11.8%). Operative deliveries rate remained stable between 11 and 12.8%. Multivariate regression showed that gestational age over 39 weeks (aOR 1.18, 95% CI [1.02; 1.35]), birth weight over 3500 g (aOR 1.62, 95% CI [1.05; 2.49]) were associated with 34DPT in patients without operative vaginal deliveries but not episiotomy. Gestational age (aOR 1.71, 95% CI [1.18; 2.47]), episiotomy (aOR 0.55, 95% CI [0.38; 0.79]) and diabetes (aOR 1.73, 95% CI [1.15; 2.61]) were associated with 34DPT among patients with operative vaginal deliveries. CONCLUSION: In a tertiary medical center model with low cesarean section rate, factors associated with 34DPT were different among patients with or without operative vaginal delivery. The question of the protective effect of mediolateral episiotomy against 34DPT in case of operative delivery deserves further investigations.

The purpose of this document is: 1) to help obstetrician-gynecologists better understand the U.S. Food and Drug Administration's regulatory process for the marketing of medical devices; 2) to educate obstetrician-gynecologists on the importance of understanding available evidence on the safety, efficacy, and indications for devices in clinical practice; 3) to encourage obstetrician-gynecologists to report safety events associated with medical devices; and 4) to provide guidance on what to consider when adopting new medical devices. The decision to incorporate new technology in a patient's care may be complex. Some medical devices are marketed for gynecologic conditions but may have unclear indications for use or unclear safety and efficacy profiles, or both. Patients often have questions about treatments and procedures involving devices, especially if a device has received media attention; therefore, a basic understanding of how devices are regulated and what type of data are or are not required before a device is brought to market is important for patient care. When adopting a new medical device, obstetrician-gynecologists should achieve proper training and should understand the evidence on safety and effectiveness and the indications for the device's use. Obstetrician-gynecologists and other health care providers should be aware of the U.S. Food and Drug Administration's Manufacturer and User Facility Device Experience database and, ideally, should become familiar with the adverse event report form and report serious adverse events that may be associated with a medical device, use errors, product quality issues, and therapeutic failures.

BACKGROUND: Birth positions may influence the risk of tears in the genital tract during birth. Birth positions are widely studied yet knowledge on genital tract tears following birth on a birth seat is inconclusive. AIM: The objective of this study was to describe the proportion of genital tract tears in women who gave birth on a birth seat compared to women who did not. METHOD: An observational cohort study based on birth information collected prospectively. In total 10 629 live, singleton, non-instrumental births in cephalic presentation were studied. RESULTS: Fewer women who gave birth on a birth seat experienced an overall intact genital tract compared to women who gave birth in any other position. Women who gave birth on a birth seat were less likely to have an episiotomy performed. Women who gave birth vaginally on a birth seat after a previous caesarean section may have an increased risk for sustaining a sphincter tear. DISCUSSION: It is important to be aware of the decreased chance of an overall intact genital tract area when giving birth on a birth seat. Furthermore, there is a possibly increased risk of sphincter tear in women having a vaginal birth after caesarean. It is required and of importance to provide pregnant women with evidence-based information on factors associated with genital tract tears including birth positions.

Poor infection control practices during childbirth are recognised as a critical factor leading to life-threatening maternal and newborn sepsis. Therefore, this paper assesses the effectiveness of clean birth kits (CBKs) to ensure a safe birthing environment. We searched PubMed, Cochrane Library and CINAHL, as well as Google Scholar, to identify both qualitative and quantitative studies on CBKs published in English up to November 2018. Studies were included if the pregnant women or women giving birth intended to use or used a CBK. The methodological quality of included papers was assessed. A total of 37 studies, 26 quantitative and 11 qualitative studies, were included. Quantitative studies showed a positive impact of CBKs on reducing the incidence of puerperal sepsis and neonatal tetanus. The review also identified CBK use to be associated with a reduction in perinatal, neonatal and young infant mortality. Qualitative studies suggested that a lack of awareness of the importance of CBKs and clean delivery practices, unavailability of CBKs and financial constraints to purchase CBKs were the potential barriers. CBKs appear to be a promising strategy to reduce maternal and neonatal morbidity and mortality. However, the current evidence is limited and further large-scale trials are required.

OBJECTIVE: The aim of our study was to evaluate the safety and the benefits of manual rotation in the management of Occiput-posterior positions in 2019. METHODS: A systematic review of literature was performed using the MEDLINE and COCHRANE LIBRARY databases, in order to identify articles concerning maternal and neonatal outcomes after a manual rotation, through January 2019. Information on study characteristics (review, author, year of publication), population, objectives and main neonatal and maternal outcomes were extracted. RESULTS: A total of 51 articles were identified and 12 articles were selected for the systematic review. The rate of successful manual rotation were about 47 to 90%. There were more success if systematic manual rotation, multiparity, engagement, spontaneous labour and maternal age<35. The 2nd stage of labour was shorter after an attempt of manual rotation. The randomised controlled trials did not find any statistical difference concerning operative deliveries or neonatal and maternal outcomes. CONCLUSION: The manual rotation is an obstetrical manoeuvre which must be regulated and only practiced by trained operators. Currently, the state of science is not sufficient to recommend the manual rotation as a systematic practice in 2019.

INTRODUCTION: In recent years new modalities of epidural analgesia maintenance (EA) have been introduced. OBJECTIVE: The objective of this study is to compare different modalities of EA maintenance for childbirth relating the time of expulsive and dilatation, motor blockade and delivery instrumentation (caesarean section, sucker, forceps, eutocic delivery or non-instrumented delivery). MATERIAL AND METHODS: Patients admitted for labor in the University Hospital Nuestra Señora de Candelaria between January 2013 and December 2015 were included. Independent modalities of EA, continuous infusion (CI), continuous infusion plus analgesia patient controlled epidural analgesia were determined as independent variables (CI+PCEA) and intermittent programmed epidural boluses plus patient controlled epidural analgesia (PIEB+PCEA). RESULTS: There are no differences in expulsive time or dilation. There is a difference in the type of instrumentation, caesarean section, sucker, forceps, eutocic delivery or non-instrumented delivery (P>.05), with the percentage of eutocic deliveries in PIEB+PCEA of 66 versus 60 in CI and 65 in CI+PCEA. The percentage of caesarean sections was 23 in CI, in CI+PCEA and PIEB+PCEA of 17. CI increases by 27% the possibility of instrumented deliveries respect to PIEB+PCEA, there is no difference between CI+PCEA and PIEB+PCEA. The motor blockade at 60 and 90minutes reaches lower values with PIEB+PCEA with an average of 0 and a range of 0-1, compared to CI+PCEA 0 (0-4). Satisfaction with CI+PCEA ranges from 2-10 and with PIEB+PCEA 0-10. CONCLUSION: It is possible to say that PIEB+PCEA is associated with higher frequency of non-instrumented deliveries. The possibility of instrumented deliveries increases with CI versus PIEB+PCEA. There is less motor block with PIEB+PCEA than with CI+PCEA. There are no differences in time of dilatation, expulsion, or patient satisfaction.

INTRODUCTION: Assisted vaginal birth (AVB) can markedly improve maternal and neonatal outcomes arising from complications in the second stage of labour. Historically, both forceps and ventouse devices have been used to assist birth; however, they are not without risk and are associated with complications, such as cephalohaematoma, retinal haemorrhage and perineal trauma. As new devices are developed to overcome the limitations of existing techniques, it is necessary to establish their efficacy and effectiveness within randomised controlled trials (RCTs). A major challenge of evaluating complex interventions (ie, invasive procedures/devices used to assist vaginal birth) is ensuring they are delivered as intended. It can be difficult to standardise intervention delivery and monitor fidelity, and account for the varying expertise of clinicians (accoucher expertise). This paper describes the protocol for a systematic review aiming to investigate the reporting of device standardisation, monitoring and training in trials evaluating complex interventions, using AVB as a case study. METHODS AND ANALYSIS: Relevant keywords and subject headings will be used to conduct a comprehensive search of MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index of Nursing and Allied Health Literature and ClinicalTrials.gov, for RCTs and pilot/feasibility studies evaluating AVB. Abstracts will be screened and full-text articles of eligible studies reviewed for inclusion. Information relating to the following categories will be extracted: standardisation of device use (ie, descriptions of operative steps, including mandatory/flexible parameters), monitoring of intervention delivery (ie, intervention fidelity, confirming that an intervention is delivered as intended) and accoucher expertise (ie, entry criteria for participation, training programmes and previous experience with the device). Risk of bias of included studies will be assessed. ETHICS AND DISSEMINATION: Ethical approval is not required because primary data will not be collected. Findings will be disseminated by publishing in a peer-reviewed journal and presentations at relevant conferences.

INTRODUCTION: Forceps delivery is associated with a high rate of levator ani muscle (LAM) trauma (avulsion) at 35%-65% whereas data on avulsion rates after vacuum delivery vary greatly. Nevertheless, a common characteristic of all previous studies carried out to evaluate the association between instrumental deliveries (forceps and vacuum) and LAM avulsion, is the fact that characteristics of the instrumentation have not been described or evaluated. The objective of this study is to compare the rate of LAM avulsion between forceps and vacuum deliveries according to the characteristics of the instrumentation. MATERIAL AND METHODS: Prospective, observational study, including 263 nulliparous women, who underwent an instrumental delivery with either Malmström vacuum or Kielland forceps. The characteristics of the instrumentation, position (anterior position and other position) and height of the fetal head at the moment of instrumentation (low instrumentation [vertex at +2 station] and mid-instrumentation [head is involved but leading part above +2 station]) were assessed. Evaluation of LAM avulsion was performed at 6 months postpartum by three-/four-dimensional transperineal ultrasound. Using the multi-view mode, a complete avulsion was diagnosed when the abnormal muscle insertion was identified in all three central slices, that is, in the plane of minimal hiatal dimensions and the 2.5-mm and 5.0-mm slices cranial to this one. To detect a 30% or 15% difference in the LAM injury rate, with 80% power and 5% α-error, we needed, respectively 42 and 99 women per study group. RESULTS: In all, 263 nulliparous individuals have been evaluated (162 vacuum deliveries, 101 forceps deliveries). Instrumentation in an occipito-anterior position was more frequent in vacuum deliveries (75.3% vs 56.4%, P = .002), whereas other positions were more frequent in the forceps deliveries group (24.7% vs 43.6%). No statistically significant differences were noted regarding the height of the fetal head at the moment of instrumentation. No statistically significant differences were found in the presence of LAM avulsion (41.4% vs 38.6%) between vacuum and forceps deliveries. The univariate analysis of the crude odds ratio was 1.17, 95% CI 0.67-1.98, P = .70 for the avulsion of the LAM and the multivariate of the adjusted OR 0.90, 95% CI; 0.53-1.55, P = .71. CONCLUSIONS: We consider that, in our population, LAM avulsion rate should not be a factor taken into account when choosing the type of instrumentation (Malmström vacuum or Kielland forceps) in an operative delivery.

OBJECTIVES: This study analyzed the changes of vaginal forceps delivery rate in Jiading Maternal and Child Health Hospital in the past 10 years in order to provide theoretical reference for reducing the rate of cesarean section and solving cephalic dystocia. MATERIAL AND METHODS: The basic information, delivery means and vaginal forceps indication of 78,811 parturients who gave birth in our hospital between January 1, 2009 to December 31, 2018 were analyzed retrospectively, and statistical analysis was carried out by analysis of variance and Chi-square test. RESULTS: In the past 10 years, there was a significant difference in the rate of vaginal forceps use among different years (p < 0. 05). With 2014 as the turning point, the rate of forceps use increased the fastest, from 0.7% in 2013 to 3.3% in 2016. The main indications of forceps increased use in our hospital from high to low were fetal distress, abnormal occipital position, prolongation of the second stage of labor and shortening of the second stage of labor. And there was significant difference among different years (p < 0.000). Although there was no significant difference among the years of labor forceps use in patients with prolonged second stage of labor and abnormal occipital position (p > 0.05), the proportion of forceps delivery in the second stage of labor was gradually decreased with 2014 as the dividing line. Although there was significant difference among the patients who shortened the second stage of labor (X2 = 23,886, p < 0.01), it ranked fourth all the time. CONCLUSIONS: In the past 10 years, the rate of forceps use has been on the rise. With the implementation of the new stage of labor and painless delivery in 2014, vaginal forceps have become the main means to solve the problem of cephalic dystocia.

OBJECTIVE: to explore and describe the use of the partogram in private hospitals in South Africa. DESIGN: an explanatory mixed method design. In-depth interviews were conducted with the midwives and midwife specialists to explicate the significance of the initial quantitative questionnaires. SETTING: a private maternity hospital in Gauteng Province, South Africa. PARTICIPANTS: 11 midwives and 3 advanced midwives working in the labour unit of the private maternity hospital. FINDINGS: although all the midwives and midwife specialists knew the purpose of the partogram, where to find the recommendations on the use of the partogram and the signs of true labour, not all were sure when the partogram had to be completed and who is accountable for plotting the findings. Fetal heart rate monitoring during the active phase of labour remains a concern. KEY CONCLUSION: the findings revealed that the midwives understood the importance of the partogram but are not using it within the parameters for which it was intended. The obstetricians intervened during labour with no or little use of the partogram. IMPLICATIONS FOR PRACTICE: the study identified the knowledge strengths and deficits of midwives working in a private hospital on partogram use that would benefit from training interventions and professional development. Evidence suggests a culture where the partogram is not central to care as obstetricians are not using the partogram. The purpose of the partogram in the private sector needs to be reviewed.

Introduction: To determine whether intrapartum translabial ultrasound (ITU) is useful for the prediction of levator ani muscle (LAM) avulsions in instrumental deliveries (vacuum and forceps). Materials and methods: Prospective, observational study, including (1/2016 - 5/2016) 77 nulliparous women, with singleton pregnancies of ≥37 weeks of gestation and with cephalic presentation, who required vacuum or forceps instrumentation to complete the delivery. The ITU parameters evaluated were Angle of Progression (AoP), Progression Distance (PD), Head Direction (HD), and Midline Angle (MLA), both at rest and with maternal push. Evaluation of LAM avulsion was performed at 6 months postpartum with 3-4D transperineal ultrasound. Complete avulsion was defined as an abnormal insertion of LAM in the lower pubic branch identified in all three central slices. Results: Data from 48 nulliparous women were finally included in the study (34 vacuum and 14 forceps). We observed no difference in obstetric parameters between the two study groups (group with avulsion of LAM -14 cases, 29.2% - and group without avulsion of LAM -34 cases, 70.8%). The "LAM avulsion group" had an AoP and a PD of 136.7 ± 22.4 and 43.5 ± 15.6, respectively, versus 141.6 ± 21.3 and 47.2 ± 16.8 recorded in the group without avulsion (NS), respectively. We obtained a ROC curve for AoP and PD with a push of 0.66 (95% CI, 0.28-1.00) and 0.57 (95% CI, 0.39-0.75), respectively. Conclusions: ITU is not a useful technique to predict the occurrence of LAM avulsion in instrumental deliveries with vacuum or forceps.

Objective: To verify the relationship between the time of clamping of the umbilical cord and the development of neonatal jaundice, the dosage of bilirubin and the need for phototherapy. Methods: Cross-sectional, retrospective study with 398 parturients at normal risk (single term gestation, no complications during gestation or delivery, birth weight between 2500 and 4499 g). The population was divided into three groups regarding the time of cord clamping: <1 min(117, 29.4%), between 1 and 3 min(228, 57.3%) and >3 min(53, 13.3%). Sociodemographic, clinical and obstetric characteristics, birth and delivery data, and maternal and perinatal outcomes were evaluated. Pearson's chi-square test, Fisher's exact test and the Kruskal-Wallis test were used for comparison between the groups. Statistical significance was considered p < .05. Results: The groups were similar in the development of jaundice (p = .370), bilirubin dosage (p = .342) and need for phototherapy (p = .515). Late clamping was more prevalent in vaginal deliveries when compared to cesarean sections (1-3 min: 64 versus 21.4%, >3 min: 16.6 versus 1%) (p < .001). There was no difference in other maternal or perinatal variables. Conclusion: The clamping time of the umbilical cord showed no association with jaundice, bilirubin dosage, or phototherapy needs in neonates at normal risk. The adoption of late clamping was more prevalent in vaginal deliveries.

Objectives Vital to implementation of the World Health Organization (WHO) Safe Childbirth Checklist (SCC), designed to improve delivery of 28 essential birth practices (EBPs), is the availability of safe birth supplies: 22 EBPs on the SCC require one or more supplies. Mapping availability of these supplies can determine the scope of shortages and need for supply chain strengthening. Methods A cross-sectional survey on the availability of functional and/or unexpired supplies was assessed in 284 public-sector facilities in 38 districts in Uttar Pradesh, India. The twenty-three supplies were categorized into three non-mutually exclusive groups: maternal (8), newborn (9), and infection control (6). Proportions and mean number of supplies available were calculated; means were compared across facility types using t-tests and across districts using a one-way ANOVA. Log-linear regression was used to evaluate facility characteristics associated with supply availability. Results Across 284 sites, an average of 16.9 (73.5%) of 23 basic childbirth supplies were available: 63.4% of maternal supplies, 79.1% of newborn supplies, and 78.7% of infection control supplies. No facility had all 23 supplies available and only 8.5% had all four medicines assessed. Significant variability was observed by facility type and district. In the linear model, facility type and distance from district hospital were significant predictors of higher supply availability. Conclusions for Practice In Uttar Pradesh, more remote sites, and primary and community health centers, were at higher risk of supply shortages. Supply chain management must be improved for facility-based delivery and quality of care initiatives to reduce maternal and neonatal harm.

INTRODUCTION: The aim of this study was to pilot Relaxbirth® (Relaxbirth®, Ltd., Helsinki, Finland), an investigational device designed to facilitate upright positioning intrapartum. The objective was to 1) compare birth outcomes with and without the use of Relaxbirth®, and 2) assess device usability. METHODS AND MATERIALS: Study design: prospective product use and retrospective case control study at one perinatal center in Ohio. INCLUSION CRITERIA: ≥18 years old, <300 lbs. women with a low-risk, term gestation of a singleton, vertex fetus, and vaginal birth between January 2013 to June 2016. Participants who used the Relaxbirth® device intrapartum (RB group) were retrospectively case-matched to controls (CON group) according to age, race, insurance, gravida/parity, gestational age and labor type. Birth outcomes (primary outcome) were compared between groups. Providers and women who used Relaxbirth® assessed usability of the device with the Modified System Usability Scale Tool (secondary outcome). RESULTS: Of the n = 60 included in the final analysis, RB women (n = 30) pushed for a shorter average duration compared to CON women (n = 30) [34 min (±48) versus 60 min (±63), p = 0.023]. RB women did not experience more adverse birth outcomes including: longer second stage duration, operative vaginal delivery, malpresentation, perineal laceration/episiotomy, higher blood loss, or low Apgars. Usability survey results were favorable (Total Average Scores: providers 74.1; RB 83.6). CONCLUSION: Clinical experience with the Relaxbirth® device was positive at this pilot site. The device was associated with favorable birth outcomes and usability, suggesting potential as a safe and novel adjunct to promote intrapartum choices, upright positioning and maternal satisfaction.
