Comparison between different epidural analgesia modalities for labor. REVISTA ESPANOLA DE ANESTESIOLOGIA Y REANIMACION 2019; 66:417-424. [PMID: 31138442 DOI: 10.1016/j.redar.2019.03.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Revised: 02/28/2019] [Accepted: 03/04/2019] [Indexed: 06/09/2023]
Abstract
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.

Exploring standardisation, monitoring and training of medical devices in assisted vaginal birth studies: protocol for a systematic review. BMJ Open 2019; 9:e028300. [PMID: 30987994 PMCID: PMC6500334 DOI: 10.1136/bmjopen-2018-028300] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 03/04/2019] [Accepted: 03/05/2019] [Indexed: 11/03/2022] Open
Abstract
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.

Effects of induction of labor prior to post-term in low-risk pregnancies: a systematic review. JBI DATABASE OF SYSTEMATIC REVIEWS AND IMPLEMENTATION REPORTS 2019; 17:170-208. [PMID: 30299344 PMCID: PMC6382053 DOI: 10.11124/jbisrir-2017-003587] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/30/2022]
Abstract
OBJECTIVE The objective of this review was to identify, assess and synthesize the best available evidence on the effects of induction prior to post-term on the mother and fetus. Maternal and fetal outcomes after routine labor induction in low-risk pregnancies at 41+0 to 41+6 gestational weeks (prior to post-term) were compared to routine labor induction at 42+0 to 42+6 gestational weeks (post-term). INTRODUCTION Induction of labor when a pregnancy exceeds 14 days past the estimated due date has long been used as an intervention to prevent adverse fetal and maternal outcomes. Over the last decade, clinical procedures have changed in many countries towards earlier induction. A shift towards earlier inductions may lead to 15-20% more inductions. Given the fact that induction as an intervention can cause harm to both mother and child, it is essential to ensure that the benefits of the change in clinical practice outweigh the harms. INCLUSION CRITERIA This review included studies with participants with expected low-risk deliveries, where both fetus and mother were considered healthy at inclusion and with no known risks besides the potential risk of the ongoing pregnancy. Included studies evaluated induction at 41+1-6 gestational weeks compared to 42+1-6 gestational weeks. Randomized control trials (n = 2), quasi-experimental trials (n = 2), and cohort studies (n = 3) were included. The primary outcomes of interest were cesarean section, instrumental vaginal delivery, low Apgar score (≤ 7/5 min.), and low pH (< 7.10). Secondary outcomes included additional indicators of fetal or maternal wellbeing related to prolonged pregnancy or induction. METHODS The following information sources were searched for published and unpublished studies: PubMed, CINAHL, Embase, Scopus, Swemed+, POPLINE; Cochrane, TRIP; Current Controlled Trials; Web of Science, and, for gray literature: MedNar; Google Scholar, ProQuest Nursing & Allied Health Source, and guidelines from the Royal College of Obstetricians and Gynaecologists, and American College of Obstetricians and Gynecologists, according to the published protocol. In addition, OpenGrey and guidelines from the National Institute for Health and Care Excellence, World Health Organization, and Society of Obstetricians and Gynaecologists of Canada were sought. Included papers were assessed by all three reviewers independently using the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI). The standardized data extraction tool from JBI SUMARI was used. Data were pooled in a statistical meta-analysis model using RevMan 5, when the criteria for meta-analysis were met. Non-pooled results were presented separately. RESULTS Induction at 41+0-6 gestational weeks compared to 42+0-6 gestational weeks was found to be associated with an increased risk of overall cesarean section (relative risk [RR] = 1.11, 95% confidence interval [CI] 1.09-1.14), cesarean section due to failure to progress (RR = 1.43, 95% CI 1.01-2.01), chorioamnionitis (RR = 1.13, 95% CI 1.05-1.21), labor dystocia (RR = 1.29, 95% CI 1.22-1.37), precipitate labor (RR = 2.75, 95% CI 1.45-5.2), uterine rupture (RR = 1.97, 95% CI 1.54-2.52), pH < 7.10 (RR = 1.9, 95% CI 1.48-2.43), and a decreased risk of oligohydramnios (RR = 0.4, 95% CI 0.24-0.67) and meconium stained amniotic fluid (RR = 0.82, 95% CI 0.75-0.91). Data lacked statistical power to draw conclusions on perinatal death. No differences were seen for postpartum hemorrhage, shoulder dystocia, meconium aspiration, 5-minute Apgar score < 7, or admission to neonatal intensive care unit. A policy of awaiting spontaneous onset of labor until 42+0-6 gestational weeks showed, that approximately 70% went into spontaneous labor. CONCLUSIONS Induction prior to post-term was associated with few beneficial outcomes and several adverse outcomes. This draws attention to possible iatrogenic effects affecting large numbers of low-risk women in contemporary maternity care. According to the World Health Organization, expected benefits from a medical intervention must outweigh potential harms. Hence, our results do not support the widespread use of routine induction prior to post-term (41+0-6 gestational weeks).

[PMID: 30412787 DOI: 10.1016/j.jogoh.2018.10.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 10/26/2018] [Accepted: 10/31/2018] [Indexed: 11/19/2022]
Abstract
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.

Abstract
OBJECTIVES The aim of this review was to agree on a definition of the obstetric anal sphincter injuries (OASIS), to determine the prevalence and risk factors. METHODS A comprehensive review of the literature on the obstetric anal sphincter injuries (OASIS), establishment of levels of evidence (NP), and grades of recommendation according to the methodology of the recommendations for clinical practice. RESULTS To classify obstetric anal sphincter injuries (OASIS), we have used the WHO-RCOG classification, which lists 4 degrees of severity. To designate obstetric anal sphincter injuries, we have used the acronym OASIS, rather than the standard French terms of "complete perineum" and "complicated complete perineum". OASIS with only isolated involvement of the EAS (3a and 3b) appears to have a better functional prognosis than OASIS affecting the IAS or the anorectal mucosa (3c and 4) (LE3). The prevalence of women with ano-rectal symptoms increases with the severity of the OASIS (LE3). In the long term, 35-60% of women who had an OASIS have anal or fecal incontinence (LE3). The prevalence of an OASI in the general population is between 0.25 to 6%. The prevalence of OASIS in primiparous women is between 1.4 and 16% and thus, should be considered more important than among the multiparous women (0.4 to 2.7%). In women with a history of previous OASIS, the risk of occurrence is higher and varies between 5.1 and 10.7% following childbirth. The priority in this context remains the training of childbirth professionals (midwives and obstetricians) to detect these injuries in the delivery room, immediately after the birth. The training and awareness of these practitioners of OASIS diagnosis improves its detection in the delivery room (LE2). Professional experience is associated with better detection of OASIS (LE3) (4). Continuing professional education of obstetrics professionals in the diagnosis and repair of OASIS must be encouraged (Grade C). In the case of second-degree perineal tear, the use of ultrasound in the delivery room improves the diagnosis of OASIS (LE2). Ultrasound decreases the prevalence of symptoms of severe anal incontinence at 1 year (LE2). The diagnosis of OASIS is improved by the use of endo-anal ultrasonography in post-partum (72h-6weeks) (LE2). The principal factors associated with OASIS are nulliparity and instrumental (vaginal operative) delivery; the others are advanced maternal age, history of OASIS, macrosomia, midline episiotomy, posterior cephalic positions, and long labour (LE2). The presence of a perianal lesion (perianal fissure, or anorectal or rectovaginal fistula) is associated with an increased risk of 4th degree lacerations (LE3). Crohn's disease without perianal involvement is not associated with an excess risk of OASIS (LE3). For women with type III genital mutilation, deinfibulation before delivery is associated with a reduction in the risk of OASIS (LE3); in this situation, deinfibulation is recommended before delivery (grade C). CONCLUSION It is necessary to use a consensus definition of the OASIS to be able to better detect and treat them.

Level of partograph utilization and its associated factors among obstetric caregivers at public health facilities in East Gojam Zone, Northwest Ethiopia. PLoS One 2018; 13:e0200479. [PMID: 30001358 PMCID: PMC6042737 DOI: 10.1371/journal.pone.0200479] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Accepted: 06/27/2018] [Indexed: 11/18/2022] Open
Abstract
Introduction The discrepancy regarding maternal mortality continues to be a health concern between developing and developed countries. The majority of global maternal deaths occur in developing countries, specifically, in the sub-Sahara African region which alone accounts for more than half of these deaths. It has been indicated that utilization of the partograph was significantly associated with improved maternal and neonatal outcomes of labour and that is why the World Health Organization recommends the universal use of the tool during labour. Therefore, this study has assessed the level of partograph use and its associated factors among obstetric caregivers in East Gojam Zone, Northwest Ethiopia. Methods A health facility based cross-sectional study was conducted among randomly selected obstetric caregivers in Northwest Ethiopia. The data were collected using a self-administered questionnaire and a clinical observation checklist. The data were entered into Epidata version 3.1, and cleaned and analyzed using SPSS version 24.0 statistical software. Result About three quarters, or 198 (72.53%), of the obstetric caregivers, had attained diploma level of education. However, 153 (56.04%) of the obstetric caregivers had what was considered to be good knowledge about the partograph, but utilization of the tool was slightly lower than their level of knowledge, 147 (53.85%). Utilization of the partograph was significantly higher among obstetric caregivers holding a Bachelor of Science degree and above, than Diploma holders (AOR (95% C.I) 2.07 (1.15–3.75)) and the use was higher among those who were regularly working in the delivery ward compared to those regularly working in the Adult Outpatient Department (AOR (95% C.I): 2.25 (1.07–4.72)). Moreover, caregivers who had a good knowledge about the partograph and who had received on the job training in obstetric care were also more likely to use the partograph during labour and delivery (AOR (95% C.I): 1.79 (1.05–3.06) and 4.85 (2.63–8.96)) respectively. Conclusion The results of this study revealed that although more than half of obstetric caregivers had a good knowledge of the partograph, the actual utilization of the tool was slightly lower than the knowledge they had. Therefore, in this study, we suggest that providing on the job obstetric care training for obstetric caregivers, about the partograph in particular, would improve partograph utilization.

Abstract
BACKGROUND The ePartogram is a tablet-based application developed to improve care for women in labor by addressing documented challenges in partograph use. The application is designed to provide real-time decision support, improve data entry, and increase access to information for appropriate labor management. This study's primary objective was to evaluate the feasibility and acceptability of ePartogram use in resource-constrained clinical settings. METHODS The ePartogram was introduced at three facilities in Zanzibar, Tanzania. Following 3 days of training, skilled birth attendants (SBAs) were observed for 2 weeks using the ePartogram to monitor laboring women. During each observed shift, data collectors used a structured observation form to document SBA comfort, confidence, and ability to use the ePartogram. Results were analyzed by shift. Short interviews, conducted with SBAs (n = 82) after each of their first five ePartogram-monitored labors, detected differences over time. After the observation period, in-depth interviews were conducted (n = 15). A thematic analysis of interview transcripts was completed. RESULTS Observations of 23 SBAs using the ePartogram to monitor 103 women over 84 shifts showed that the majority of SBAs (87-91%) completed each of four fundamental ePartogram tasks-registering a client, entering first and subsequent measurements, and navigating between screens-with ease or increasing ease on their first shift; this increased to 100% by the fifth shift. Nearly all SBAs (93%) demonstrated confidence and all SBAs demonstrated comfort in using the ePartogram by the fifth shift. SBAs expressed positive impressions of the ePartogram and found it efficient and easy to use, beginning with first client use. SBAs noted the helpfulness of auditory reminders (indicating that measurements were due) and visual alerts (signaling abnormal measurements). SBAs expressed confidence in their ability to interpret and act on these reminders and alerts. CONCLUSIONS It is feasible and acceptable for SBAs to use the ePartogram to support labor management and care. With structured training and support during initial use, SBAs quickly became competent and confident in ePartogram use. Qualitative findings revealed that SBAs felt the ePartogram improved timeliness of care and supported decision-making. These findings point to the ePartogram's potential to improve quality of care in resource-constrained labor and delivery settings.

Abstract
The Food and Drug Administration (FDA or we) is classifying the pressure wedge for the reduction of cesarean delivery into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the pressure wedge for the reduction of cesarean delivery's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens.

Abstract
PURPOSE To report a case series of neonatal ophthalmic trauma induced by forceps-assisted vaginal delivery. METHODS Retrospective, non-comparative case series focusing on presentation and long-term outcomes. RESULTS Eleven cases of ophthalmic injury secondary to forceps delivery (7 male, 4 female) from October 1997 to July 2014 are presented. Eight cases were born at a single center from January 2006 to July 2014, a rate of 1 case per 413 forceps-assisted deliveries. Follow-up ranged from 2 months to 17 years. Three cases had self-limiting eyelid bruising only. There was one case each of vitreous hemorrhage and hyphema, which resolved spontaneously. There were two cases of oculomotor nerve palsy associated with intracranial hemorrhage, both requiring surgical ptosis repair at 3 and 5 weeks old, respectively. There was one case of facial nerve palsy. Four cases sustained corneal trauma, manifesting as corneal edema in three cases at birth. The fourth of these cases presented at age 4.5 years with corneal scarring and amblyopia. Resulting astigmatism in these four cases ranged from 3.5 to 7.5 diopters and best-corrected visual acuity ranged from 6/12 to 6/36 Snellen at last follow-up. CONCLUSIONS Although rare, ophthalmic trauma secondary to forceps-assisted delivery can result in a wide spectrum of anatomical injuries, which may be self-limiting or cause significant long-term visual impairment. The authors recommend awareness among obstetricians and pediatricians of these injuries, and referral to the ophthalmologist of any newborn delivered by forceps with evidence of compressive trauma such as scalp or eyelid bruising to rule out the presence of more serious ophthalmic trauma.

Abstract
In primitive cultures, women chose to give birth in upright positions such as squatting or sitting, because these positions stimulate a physiological birth. In this way, in order to make easier the delivery support tools such as birthing chair (BC) are discovered. Later, with the medicalization of childbirth, the lithotomy position was introduced as standard practice, with the aim of promoting comfort to the birth attendant. Currently, this position is still prevalent in the hospital environment. The World Health Organization recommendations, stresses the importance of providing impartial information on birthing positions to women, so that she will decide how to give birth without professional influence as a limiting factor in maternal posture. The aim of this review is to make known the utility of the BC, the advantages and disadvantages associated with it, to make it an available resource in vertical childbirth. The BC is a low rise seat horseshoe shaped stable and sturdy structure, and sitting in the chair women acquire squatting position, considered the most natural. The BC is considered a useful tool for childbirth upright. Giving birth using the BC seems to be protective against episiotomies and Kristeller maneuver, provides comfort and empowerment of women and helps them to have a more positive birth experience.

Abstract
PURPOSE The decline in the use of forceps in operative deliveries over the last two decades raises questions about teaching hospitals' ability to provide trainees with adequate experience in the use of forceps. The authors examined (1) the number of operative deliveries performed in teaching and nonteaching hospitals, and (2) whether teaching hospitals performed a sufficient number of forceps deliveries for physicians to acquire and maintain competence. METHOD The authors used State Inpatient Data from nine states to identify all women hospitalized for childbirth in 2008. They divided hospitals into three categories: major teaching, minor teaching, and nonteaching. They calculated delivery volumes (total operative, cesarean, vacuum, forceps, two or more methods) for each hospital and compared data across hospital categories. RESULTS The sample included 1,344,305 childbirths in 835 hospitals. The mean cesarean volumes for major teaching, minor teaching, and nonteaching hospitals were 969.8, 757.8, and 406.9. The mean vacuum volumes were 301.0, 304.2, and 190.4, and the mean forceps volumes were 25.2, 15.3, and 8.9. In 2008, 31 hospitals (3.7% of all hospitals) performed no vacuum extractions, and 320 (38.3%) performed no forceps deliveries. In 2008, 13 (23%) major teaching and 44 (44%) minor teaching hospitals performed five or fewer forceps deliveries. CONCLUSIONS Low forceps delivery volumes may preclude many trainees from acquiring adequate experience and proficiency. These findings highlighted broader challenges, faced by many specialties, in ensuring that trainees and practicing physicians acquire and maintain competence in infrequently performed, highly technical procedures.

Abstract
Caesarean section rates are rising across Europe, and concerns exist that increases are not clinically indicated. Societal, cultural and health system factors have been identified as influential. Former communist (transition) countries have experienced radical changes in these potential determinants, and we, therefore, hypothesized they may exhibit differing trends to non-transition countries. By analysing data from the WHO Europe Health for All Database, we find transition countries had a relatively low caesarean section rate in 2000 but have since experienced more rapid increases than other countries (average annual percentage change 7.9 vs. 2.4).

Abstract
BACKGROUND The use of fetal destructive instruments found in curio cabinets may be unfathomable; however, these instruments continue to have a role in select cases. CASE A 30-year-old multigravida at 40 weeks' gestation had 3 prior normal vaginal deliveries in Africa followed by a cesarean delivery with a complicated postoperative course in the United States. She was intent on having a vaginal delivery, despite repeated recommendations for surgery due to nonreassuring fetal status. After fetal demise and subsequent arrest of labor, vaginal cephalocentesis and fetal extraction were used to achieve delivery. CONCLUSION Fetal destructive procedures, such as the one described here, have a role in modern obstetrics in select cases. In addition, despite an unfortunate fetal outcome, respect for patient autonomy is paramount and is consistent with the recommendations of the American Congress of Obstetricians and Gynecologists.

Abstract
This paper presents 35 years of history of operative vaginal delivery at the Port Moresby General Hospital (PMGH). From the early 1970s when Dr. G.C. Bird was appointed as Head of Obstetrics at PMGH, vacuum extraction has been the preferred method of assisted vaginal delivery. In the early 1970s, Dr Bird began to experiment with more effective configurations of the then standard metal Malmstrom vacuum extraction cup: the Bird anterior cup was introduced in 1973 and the posterior cup in 1974. These modifications to the vacuum extractor cup allowed for more effective placement of the cup on the flexion point on the fetal head thereby facilitating more successful vacuum-assisted delivery. Between 1977 and 2010 there were a total of 11,458 vacuum extractions (average rate 3.9%) performed, with an average failure rate of 2.5%. During the same period there were 565 vaginal forceps deliveries (rate 0.2%), 11,550 caesarean sections (rate 3.9%) and 182 symphysiotomies (all for failed vacuum extraction procedures) performed. Over the period trends that are noted include a slowly rising caesarean section rate from 2% in the 1970s to nearly 5% in the current decade. Over the same period the assisted vaginal delivery rate has dropped from 10-15% in the 1970s to 3-4% since 2000. The combined fresh stillbirth and early neonatal mortality rate for infants > or = 1.5 kg and > or = 2.5 kg for the period was 11.3/1000 and 9.5/1000 respectively, and compares to a combined fresh stillbirth and early neonatal mortality rate of 8.7/1000 for assisted vaginal delivery.

Abstract
The Food and Drug Administration (FDA) is classifying the hemorrhoid prevention pressure wedge into class II (special controls). The special controls will apply to the device in order to provide a reasonable assurance of safety and effectiveness of the device. A hemorrhoid prevention pressure wedge provides support to the perianal region during the labor and delivery process.

No reduction in instrumental vaginal births and no increased risk for adverse perineal outcome in nulliparous women giving birth on a birth seat: results of a Swedish randomized controlled trial. BMC Pregnancy Childbirth 2011; 11:22. [PMID: 21435238 PMCID: PMC3071335 DOI: 10.1186/1471-2393-11-22] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2010] [Accepted: 03/24/2011] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The WHO advises against recumbent or supine position for longer periods during labour and birth and states that caregivers should encourage and support the woman to take the position in which she feels most comfortable. It has been suggested that upright positions may improve childbirth outcomes and reduce the risk for instrumental delivery; however RCTs of interventions to encourage upright positions are scarce. The aim of this study was to test, by means of a randomized controlled trial, the hypothesis that the use of a birthing seat during the second stage of labor, for healthy nulliparous women, decreases the number of instrumentally assisted births and may thus counterbalance any increase in perineal trauma and blood loss. METHODS A randomized controlled trial in Sweden where 1002 women were randomized to birth on a birth seat (experimental group) or birth in any other position (control group). Data were collected between November 2006 and July 2009. The primary outcome measurement was the number of instrumental deliveries. Secondary outcome measurements included perineal lacerations, perineal edema, maternal blood loss and hemoglobin. Analysis was by intention to treat. RESULTS The main findings of this study were that birth on the birth seat did not reduce the number of instrumental vaginal births, there was an increase in blood loss between 500 ml and 1000 ml in women who gave birth on the seat but no increase in bleeding over 1000 ml and no increase in perineal lacerations or perineal edema. CONCLUSIONS The birth seat did not reduce the number of instrumental vaginal births. The study confirmed an increased blood loss 500 ml - 1000 ml but not over 1000 ml for women giving birth on the seat. Giving birth on a birth seat caused no adverse consequences for perineal outcomes and may even be protective against episiotomies.

Abstract
OBJECTIVE To determine whether training traditional birth attendants to manage several common perinatal conditions could reduce neonatal mortality in the setting of a resource poor country with limited access to healthcare. DESIGN Prospective, cluster randomised and controlled effectiveness study. SETTING Lufwanyama, an agrarian, poorly developed district located in the Copperbelt province, Zambia. All births carried out by study birth attendants occurred at mothers' homes, in rural village settings. PARTICIPANTS 127 traditional birth attendants and mothers and their newborns (3559 infants delivered regardless of vital status) from Lufwanyama district. INTERVENTIONS Using an unblinded design, birth attendants were cluster randomised to intervention or control groups. The intervention had two components: training in a modified version of the neonatal resuscitation protocol, and single dose amoxicillin coupled with facilitated referral of infants to a health centre. Control birth attendants continued their existing standard of care (basic obstetric skills and use of clean delivery kits). MAIN OUTCOME MEASURES The primary outcome was the proportion of liveborn infants who died by day 28 after birth, with rate ratios statistically adjusted for clustering. Secondary outcomes were mortality at different time points; and comparison of causes of death based on verbal autopsy data. RESULTS Among 3497 deliveries with reliable information, mortality at day 28 after birth was 45% lower among liveborn infants delivered by intervention birth attendants than control birth attendants (rate ratio 0.55, 95% confidence interval 0.33 to 0.90). The greatest reductions in mortality were in the first 24 hours after birth: 7.8 deaths per 1000 live births for infants delivered by intervention birth attendants compared with 19.9 per 1000 for infants delivered by control birth attendants (0.40, 0.19 to 0.83). Deaths due to birth asphyxia were reduced by 63% among infants delivered by intervention birth attendants (0.37, 0.17 to 0.81) and by 81% within the first two days after birth (0.19, 0.07 to 0.52). Stillbirths and deaths from serious infection occurred at similar rates in both groups. CONCLUSIONS Training traditional birth attendants to manage common perinatal conditions significantly reduced neonatal mortality in a rural African setting. This approach has high potential to be applied to similar settings with dispersed rural populations. Trial registration Clinicaltrials.gov NCT00518856.

Abstract
BACKGROUND Instrumental or assisted vaginal birth is commonly used to expedite birth for the benefit of either mother or baby or both. It is sometimes associated with significant complications for both mother and baby. The choice of instrument may be influenced by clinical circumstances, operator choice and availability of specific instruments. OBJECTIVES To evaluate different instruments in terms of achieving a vaginal birth and avoiding significant morbidity for mother and baby. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2010). SELECTION CRITERIA Randomised controlled trials of assisted vaginal delivery using different instruments. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality, extracted the data, and checked them for accuracy. MAIN RESULTS We included 32 studies (6597 women) in this review. Forceps were less likely than the ventouse to fail to achieve a vaginal birth with the allocated instrument (risk ratio (RR) 0.65, 95% confidence interval (CI) 0.45 to 0.94). However, with forceps there was a trend to more caesarean sections, and significantly more third- or fourth-degree tears (with or without episiotomy), vaginal trauma, use of general anaesthesia, and flatus incontinence or altered continence. Facial injury was more likely with forceps (RR 5.10, 95% CI 1.12 to 23.25). Using a random-effects model because of heterogeneity between studies, there was a trend towards fewer cases of cephalhaematoma with forceps (average RR 0.64, 95% CI 0.37 to 1.11).Among different types of ventouse, the metal cup was more likely to result in a successful vaginal birth than the soft cup, with more cases of scalp injury and cephalhaematoma. The hand-held ventouse was associated with more failures than the metal ventouse, and a trend to fewer than the soft ventouse.Overall forceps or the metal cup appear to be most effective at achieving a vaginal birth, but with increased risk of maternal trauma with forceps and neonatal trauma with the metal cup. AUTHORS' CONCLUSIONS There is a recognised place for forceps and all types of ventouse in clinical practice. The role of operator training with any choice of instrument must be emphasised. The increasing risks of failed delivery with the chosen instrument from forceps to metal cup to hand-held to soft cup vacuum, and trade-offs between risks of maternal and neonatal trauma identified in this review need to be considered when choosing an instrument.

Abstract
This cross-sectional cohort study explored the impact of the use of clean delivery-kit (CDK) on morbidity due to newborn umbilical cord and maternal puerperal infections. Kits were distributed from primary-care facilities, and birth attendants received training on kit-use. A nurse visited 334 women during the first week postpartum to administer a structured questionnaire and conduct a physical examination of the neonate and the mother. Results of bivariate analysis showed that neonates of mothers who used a CDK were less likely to develop cord infection (p = 0.025), and mothers who used a CDK were less likely to develop puerperal sepsis (p = 0.024). Results of multiple logistic regression analysis showed an independent association between decreased cord infection and kit-use [odds ratio (OR) = 0.42, 95% confidence interval (CI) 0.18-0.97, p = 0.041)]. Mothers who used a CDK also had considerably lower rates of puerperal infection (OR = 0.11, 95% CI 0.01-1.06), although the statistical strength of the association was of borderline significance (p = 0.057). The use of CDK was associated with reductions in umbilical cord and puerperal infections.

Abstract
Operative vaginal delivery has been maligned since the days of W.J. Little with the word "forceps" becoming nearly synonymous with "Birth Injury" and "Cerebral Palsy." However in his presentation to the Obstetrical Society of London in 1861, Little's emphasis was on difficult labors being the culprit in subsequent disabilities in the offspring. Instrumented deliveries in that era were the end result of a long, obstructed labor performed for maternal benefit and to avoid a destructive procedure to the fetus thus allowing a chance at life. If there had been a normal progress in labor, operative assistance for delivery would not have been needed. Thus, was it the instrument or the obstructed labor that led to fetal injury? In this article, we will review what injuries to the fetus and the mother can be directly attributable to the instrument. We will explore the processes of labor, conduct of labor management, and concurrent fetal factors that can modulate the occurrence of birth trauma. Evidence regarding inexperience and improper use as contributing to injury will also be explored.

Abstract
OBJECTIVE To compare the efficacy of transcervical Foley catheter alone (Foley) to transcervical Foley catheter with extraamniotic saline infusion for labor induction and cervical ripening in women with an unfavorable cervix. METHODS This was a multicenter, randomized, controlled trial of women presenting for labor induction with a singleton, cephalic fetus, intact membranes, and unfavorable cervix (Bishop score 6 or less). Eligible women were randomly assigned to receive either Foley catheter alone or Foley catheter with extraamniotic saline infusion. All women received concurrent oxytocin administration. The primary study outcome was the induction-to-delivery interval. Secondary outcomes included cesarean delivery, maternal infectious outcomes, and immediate neonatal outcomes. Analysis was by intent to treat. RESULTS One hundred eighty-eight women met eligibility criteria and were randomly assigned (Foley plus extraamniotic saline infusion, n=97; Foley, n=91). Baseline demographic characteristics, including parity, gestational age, and Bishop score were similar between the study groups. The median induction-to-delivery interval in the extraamniotic saline infusion arm (12.6 hours, interquartile range 9.3-18.8 hours) was similar to that in the Foley arm (13.4 hours, interquartile range 9.6-17.5 hours) (P=. 70). The proportion of women delivered by 24 hours was comparable between groups (delivery 24 hours, extraamniotic saline infusion 89.7%, Foley 87.9%, P=.70), as was the rate of cesarean delivery (Foley 18.7%, extraamniotic saline infusion 27.8%, P=.14). No significant differences were noted between the study groups with respect to rate of chorioamnionitis, endometritis, or immediate birth outcomes. CONCLUSION In women with an unfavorable cervix, the addition of extraamniotic saline infusion to a transcervical Foley catheter does not improve efficacy for labor induction.

Comparing mechanical fetal response during descent, crowning, and restitution among deliveries with and without shoulder dystocia. Am J Obstet Gynecol 2007; 196:539.e1-5.

Abstract
OBJECTIVE Previous computer simulations of shoulder dystocia (SD) explored the effect of SD itself on the mechanical response of the fetus. Our objective was to perform a mechanical simulation study to explore the variations in fetal response during routine, unilateral SD (USD), and bilateral SD (BSD) deliveries. STUDY DESIGN Using a biofidelic birthing simulator, we performed 30 experiments mimicking passage of the fetus through the pelvis. For routine deliveries, we engaged the fetal head and allowed it to progress through cardinal movements using typical uterine contraction forces. Deliveries stopped when the head restituted externally to left occiput anterior (LOA) position. The identical procedure was repeated for USD deliveries, except we obstructed the anterior shoulder on the symphysis pubis; for BSD, the posterior shoulder was also impacted on the sacral promontory. For each delivery we continuously measured head rotation, brachial plexus (BP) stretch and neck extension, selecting peak values for analysis. Maximum rotation, BP stretch, and extension were compared among groups using analysis of variance, with P < .05 considered significant. RESULTS Among routine, USD, and BSD deliveries, mean peak BP stretch varied between 10% and 21%, rotation varied between 70 degrees and 77 degrees, and extension varied between 6% and 18%. Greatest stretch occurred in the posterior BP during descent in non-SD deliveries, whereas anterior BP stretch, rotation, and extension were similar among the 3 types of deliveries. CONCLUSION Quantifiable mechanical response occurs in routine and SD deliveries. Posterior BP stretch is significantly longer for routine deliveries than either USD or BSD deliveries. By itself, shoulder dystocia does not pose additional risk of brachial plexus stretch over routine deliveries.

Abstract
A study was carried out in Misungwi and Kwimba Districts, Tanzania to determine the effectiveness of clean delivery kits in preventing cord infection and puerperal sepsis and to provide qualitative information on community acceptability, correct use, and appropriateness of the kits. This study involved pregnant women aged 18-45 years old. In the delivery kit intervention population, the Maternal and Child Health Aide (MCHA) assigned to the health facility provided pregnant mothers with a clean delivery kit on their first antenatal visit. She explained how to use each of the kit components, with the aid of pictorial instructions included in the kit. The pregnant mothers were asked to convey the information to whoever assisted them during delivery. The MCHA also gave them health education based on the principles of the "six cleans" recognized by WHO (i.e., clean hands, clean perineum, clean delivery surface, clean cord cutting and tying instruments, clean cutting surface). Women received the clean delivery kit free of charge in accordance with the randomised stepped-wedge design schedule. During the first week following delivery, the Village Health Workers (VHWs) from both the intervention and control groups made two visits to the households of mothers who had delivered. They administered questionnaire about delivery to mother and birth attendant. During the two scheduled postpartum visits, those who were suspected to have puerperal sepsis or cord infection of the baby were referred to the health facility clinician for confirmation. Results indicated that use of clean delivery kit had a positive effect on reducing both cord infection and puerperal sepsis. The use of a clean home delivery kit coupled with an educational intervention about the "six cleans" had a significant effect on reducing the incidence of cord infection and puerperal sepsis among women enrolled in the study. In low resource settings where home birth is common and clean delivery supplies are scarce, disposable kits can be made available through health clinics, markets, pharmacies or other channels to help reduce rates of infection.

Abstract
OBJECTIVE The purpose of this study was to create a new instrument for the training of doctors in the use of forceps and to compare the trajectories of forceps blades between junior and senior obstetricians. STUDY DESIGN We equipped a simulator and forceps with spatial location sensors. The head of the fetus was in an occipitoanterior location, at a "+5" station. Forceps blade trajectories were analyzed subjectively with the 3-dimensional spatial graph and objectively based on 3 points of special interest. Each obstetrician performed 4 forceps blades placements. We compared the trajectories of junior and senior obstetricians. RESULTS For senior operators, spatial dispersion was "excellent," "very good," or "good" in 92% of cases, whereas this was the case for only 38% of junior doctors (92% vs 38%; P < .001). CONCLUSION A new instrument has been designed to demonstrate the trajectory of forceps blades during application in a simulator. The instrument captures the difference in experience between senior and junior clinicians.

Complementary methods in obstetrics are related to humanization of delivery and woman's decision on the mode of delivery in normal labor. The methods include various birthing positions, aids such as delivery chair, birthing wheel, etc., and water delivery. Results of recent studies comparing these methods with classic delivery in supine position are presented. The advantages of these alternative methods of delivery include shorter duration of delivery, reduced need of labor induction, lower use of analgesics, and women's acceptance of these methods of delivery with the same level of maternal and neonatal safety as in classic delivery. All these advantages apply to water delivery providing the prerequisities, contraindications and measures of surveillance are strictly met.

Abstract
Anal incontinence (AI) is a significant problem that causes social and hygienic inconvenience. The true prevalence of AI is difficult to estimate due to inconsistencies in research methods, but larger studies suggest a rate of 2-6% for incontinence to stool. There is a significant association between sonographically detected anal sphincter defects and symptoms of AI. The intrapartum factors most consistently associated with a higher risk of AI include: forceps delivery, third or fourth degree tears, and length of the second stage of labor. Fetal weight of > 4,000 g is also associated with AI. Repair of the sphincter can be performed in either an overlapping or an end-to-end fashion, with similar results for both methods. The role of cesarean delivery for the prevention of AI remains unclear, and further study should be devoted to this question.

Abstract
OBJECTIVE To determine the prevalence of fecal incontinence after childbirth and to identify the risk factors. METHODS This was a prospective observational study with a consecutive inclusion of 525 women who delivered over a three months period. Women were questioned about their fecal continence four days and six weeks after delivery. RESULTS The incidence of fecal incontinence four days and six weeks after childbirth was respectively 8.8% and 3.3%. The risk factors for fecal incontinence at 4 days after childbirth were instrumental delivery by forceps (adjusted odds ratio 8.64, 95% confidence interval 3.55-21.0, p < 0.001) and unassisted delivery at home (adjusted OR 8.06, 95% CI 1.30-50.0, p = 0.025). Independent risk factors for the presence of fecal incontinence 6 weeks later were: instrumental forceps delivery (adjusted OR 10.8, 95% CI 2.82-41.3, p = 0.001), unassisted delivery at home (adjusted OR 50.0, 95% CI 3.09-802, p = 0.006), bi-parietal diameter of the newborn > 93 mm (adjusted OR 4.56, 95% CI 1.46-14.1, p = 0.009) and maternal age >30 years (adjusted OR 4.60, 95% CI 1.11-19.1, p = 0.036). CONCLUSION Fecal incontinence is common after childbirth and its prevalence is predominantly associated with instrumental delivery, unassisted delivery at home, bi-parietal diameter of the newborn and maternal age.

Risk factors for obstetrical anal sphincter lacerations. Int Urogynecol J 2005; 16:304-7.

Abstract
The objective of this study was to identify the rate of anal sphincter lacerations in a large population-based database and analyze risk factors associated with this condition. Data were obtained from Pennsylvania Healthcare Cost Containment Council (PHC4) regarding all cases of obstetrical third and fourth degree perineal lacerations that occurred during a 2-year period from January 1990 to December 1991. Modifiable risk factors associated with this condition were analyzed, specifically episiotomy, forceps-assisted vaginal delivery, forceps with episiotomy, vacuum-assisted vaginal delivery, and vacuum with episiotomy. There were a total of 168,337 deliveries in 1990 and 165,051 deliveries in 1991 in Pennsylvania. Twenty-two percent (n = 74,881) of the deliveries were by cesarean section and were excluded from analysis. Among the remaining 258,507 deliveries, there were 18,888 (7.3%) third and fourth degree lacerations. Instrumental vaginal delivery, particularly with use of episiotomy, increased the risk of laceration significantly [forceps odds ratio (OR): 3.84, forceps with episiotomy OR: 3.89, vacuum OR: 2.58, vacuum with episiotomy OR: 2.93]. Episiotomy on the whole was associated with a threefold increase in the risk of sphincter tears. However, episiotomy in the absence of instrumental delivery seems to be protective with an OR of 0.9 [95% confidence interval (CI): 0.88-0.93]. Instrumental vaginal delivery, particularly forceps delivery, appears to be an important risk factor for anal sphincter tears. The risk previously attributed to episiotomy is probably due to its association with instrumental vaginal delivery. Forceps delivery is associated with higher occurrence of anal sphincter injury compared to vacuum delivery.

Abstract
OBJECTIVE This is a descriptive study that tested the maximum traction residents could apply to forceps during simulations. Visual feedback was then used to reinforce an optimal range of traction, and the ability of residents to reproduce this pull when blinded was assessed. METHODS Fifty-five residents participated in 6 pulling exercises using an isometric strength testing unit with a real-time computer printout of the force applied. Maximum traction was determined for male and female residents in standing and sitting positions. Visual feedback was then used to estimate whether residents could be trained to reproduce an optimal force range of 30-45 pounds. Data were analyzed using a repeated measures analysis of variance. RESULTS When asked to produce a maximum pull, male residents could generate significantly more force than females in the standing and sitting positions (P < .001). In general, all residents of both sexes generated more traction in the sitting position than in the standing position. The mean maximum traction produced by men in the standing and sitting positions was 69.5 and 85.8 pounds, respectively. For women, the mean maximum force generated was 45.5 pounds in the standing position and 61.3 pounds in the sitting position. Residents could easily reproduce an appropriate force in the short term after training by computer-assisted visual feedback. CONCLUSION Motor learning tasks using visual feedback can be useful in training practitioners to produce appropriate traction forces during obstetric forceps deliveries. Residents of both sexes, but especially men, can generate traction forces exceeding the recommended limit. Unless tempered by training, forces generated from the sitting position in particular can often exceed the preferred range. LEVEL OF EVIDENCE II-3.
