Improving management of first and second stages of labour in low- and middle-income countries.

Labour care must balance aspirations of parents with vigilance for unanticipated calamities. The 'on-site midwife-led primary care birth unit' facilitates this. The World Health Organization have replaced the traditional partograph with the 'Labour Care Guide'. An implementation project in Botswana included the mnemonic COPE: Companion, Oral fluids, Pain relief and Eliminate the supine position. The Parto-Ma project in Tanzania used guidelines, training and support to improve childbirth outcomes. We list labour practices supported by recent evidence, and highlight new developments. Foetal macrosomia increases risk but mistaken diagnosis increases caesarean births. Obstructed labour is a complex clinical diagnosis, and is difficult to predict. For shoulder dystocia prioritise delivery of the posterior shoulder, facilitated if needed by posterior axilla sling traction. 'Extended balloon labour induction' with two or three Foley catheters side by side, may reduce risks associated with uterine stimulants. Bedside ultrasound may facilitate the diagnosis of cephalic malpositions and malpresentations.

Phase separation as a strategy to prevent sulfide-related drawbacks in methanogenesis: performance and energetic aspects.

The establishment of sulfate (SO42-) reduction during methanogenesis may considerably hinder the efficient energetic exploitation of methane, once removing sulfide from biogas is obligate and can be costly. In addition, sulfide generation can negatively impact the performance of methanogens by triggering substrate competition and sulfide inhibition. This study investigated the impacts of removing SO42- during fermentation on the performance of a second-stage methanogenic continuous reactor (R2), comparing the results with those obtained in a single-stage system (R1) fed with SO42--rich wastewater (SO42- of up to 400 mg L-1, COD/SO42- of 3.12-12.50). The organic load (OL) was progressively increased to 5.0 g COD d-1 in both reactors, showing completely discrepant performances. Sulfate-reducing bacteria outperformed methanogens in the consumption for organic matter during the start-up phase (OL = 2.5 g COD d-1) in R1, directing up to 73% of the electron flow to SO42- reduction. An efficient methanogenic activity was established in R1 only after decreasing the OL to 0.625 g COD d-1, after which methanogenesis prevailed by consuming ca. 90% of the removed COD. Nevertheless, high sulfide proportions (up to 3.1%) were measured in biogas. Conversely, methanogenesis was promptly established in R2, resulting in a methane-rich (> 80%) and sulfide-free biogas regardless of the operating condition. From an economic perspective, processing the biogas evolved from R2 would be cheaper, although the techno-economic impacts of managing the sulfur pollution in the fermentative reactor still need to be understood.

The physiology and pharmacology of oxytocin in labor and in the peripartum period.

Oxytocin is a reproductive hormone implicated in the process of parturition and widely used during labor. Oxytocin is produced within the supraoptic nucleus and paraventricular nucleus of the hypothalamus and released from the posterior pituitary lobe into the circulation. Oxytocin is released in pulses with increasing frequency and amplitude in the first and second stages of labor, with a few pulses released in the third stage of labor. During labor, the fetus exerts pressure on the cervix of the uterus, which activates a feedforward reflex-the Ferguson reflex-which releases oxytocin. When myometrial contractions activate sympathetic nerves, it decreases oxytocin release. When oxytocin binds to specific myometrial oxytocin receptors, it induces myometrial contractions. High levels of circulating estrogen at term make the receptors more sensitive. In addition, oxytocin stimulates prostaglandin synthesis and release in the decidua and chorioamniotic membranes by activating a specific type of oxytocin receptor. Prostaglandins contribute to cervical ripening and uterine contractility in labor. The oxytocin system in the brain has been implicated in decreasing maternal levels of fear, pain, and stress, and oxytocin release and function during labor are stimulated by a social support. Moreover, studies suggest, but have not yet proven, that labor may be associated with long-term, behavioral and physiological adaptations in the mother and infant, possibly involving epigenetic modulation of oxytocin production and release and the oxytocin receptor. In addition, infusions of synthetic oxytocin are used to induce and augment labor. Oxytocin may be administered according to different dose regimens at increasing rates from 1 to 3 mIU/min to a maximal rate of 36 mIU/min at 15- to 40-minute intervals. The total amount of synthetic oxytocin given during labor can be 5 to 10 IU, but lower and higher amounts of oxytocin may also be given. High-dose infusions of oxytocin may shorten the duration of labor by up to 2 hours compared with no infusion of oxytocin; however, it does not lower the frequency of cesarean delivery. When synthetic oxytocin is administered, the plasma concentration of oxytocin increases in a dose-dependent way: at infusion rates of 20 to 30 mIU/min, plasma oxytocin concentration increases approximately 2- to 3-fold above the basal level. Synthetic oxytocin administered at recommended dose levels is not likely to cross the placenta or maternal blood-brain barrier. Synthetic oxytocin should be administered with caution as high levels may induce tachystole and uterine overstimulation, with potentially negative consequences for the fetus and possibly the mother. Of note, 5 to 10 IU of synthetic oxytocin is often routinely given as an intravenous or intramuscular bolus administration after delivery to induce uterine contractility, which, in turn, induces uterine separation of the placenta and prevents postpartum hemorrhage. Furthermore, it promotes the expulsion of the placenta.

Duration time of labor progression for pregnant women of vaginal birth after cesarean in Hubei, China.

OBJECTIVE: There have been limited reports on the duration of labor progression in pregnant women undergoing vaginal birth after cesarean (VBAC). This study aimed to investigate the duration of labor progression during VBAC in Hubei, China. METHODS: A total of 359 pregnant women undergoing VBAC were enrolled as the VBAC group, meeting the following criteria: singleton pregnancy, gestational age ≥ 37 weeks, live birth, history of cesarean delivery, and a willingness to attempt a vaginal delivery. At the same time, 359 primiparas successfully undergoing vaginal delivery were randomly enrolled in the control group at a 1:1 ratio. Subsequently, the durations of the first, second, and third stages of labor were comparatively analyzed between the two groups. RESULTS: The duration of the first, second, and total stages of labor in the VBAC group was significantly shorter than that in the control group (p < 0.05). There was no significant difference in the duration of the third stage of labor between the two groups (p > 0.05). The amount of blood loss, the rate of postpartum hemorrhage (PPH), and episiotomy were higher in the VBAC group than in the control group (p < 0.05). The rate of labor analgesia and intrapartum fever in the VBAC group was significantly lower than that in the control group (p < 0.05). CONCLUSION: The duration of labor progression of the first, second, and total stages of VBAC is shorter than that in primiparous women in our observation in China.

Duration of the active first stage of labour and severe perineal lacerations and maternal postpartum complications: a population-based cohort study.

OBJECTIVE: The impact of first stage labour duration on maternal outcomes is sparsely investigated. We aimed to study the association between a longer active first stage and maternal complications in the early postpartum period. DESIGN: A population-based cohort study. SETTING: Regions of Stockholm and Gotland, Sweden, 2008-2020. POPULATION: A cohort of 159 459 term, singleton, vertex pregnancies, stratified by parity groups. METHODS: The exposure was active first stage duration, categorised in percentiles. Poisson regression analysis was performed to estimate the adjusted relative risk (aRR) and the 95% confidence interval (95% CI). To investigate the effect of second stage duration on the outcome, mediation analysis was performed. MAIN OUTCOME MEASURES: Severe perineal lacerations (third or fourth degree), postpartum infection, urinary retention and haematoma in the birth canal or ruptured sutures. RESULTS: The risks of severe perineal laceration, postpartum infection and urinary retention increased with a longer active first stage, both overall and stratified by parity group. The aRR increased with a longer active first stage, using duration of <50th percentile as the reference. In the ≥90th percentile category, the aRR for postpartum infection was 1.64 (95% CI 1.46-1.84) in primiparous women, 2.43 (95% CI 1.98-2.98) in parous women with no previous caesarean delivery (CD) and 2.33 (95% CI 1.65-3.28) in parous women with a previous CD. The proportion mediated by second stage duration was 33.4% to 36.9% for the different outcomes in primiparous women. The risk of haematoma or ruptured sutures did not increased with a longer active first stage. CONCLUSIONS: Increasing active first stage duration is associated with maternal complications in the early postpartum period.

Active pelvic movements on a Swiss ball reduced labour duration, pain, fatigue and anxiety in parturient women: a randomised trial.

QUESTION: How much do active pelvic movements on a Swiss ball during labour affect maternal and neonatal outcomes? METHOD: A randomised trial with concealed allocation, blinded assessors and intention-to-treat analysis. PARTICIPANTS: Two-hundred parturient women. INTERVENTION: The experimental group performed pelvic anteversion and retroversion, lateral pelvic tilts and circular hip movements according to individual obstetric evaluation (foetal station and position, cervical dilatation and the presence of early pushing urge) on a Swiss ball. The control group received usual care. Both groups were permitted to walk and shower. OUTCOME MEASURES: The primary outcome was the duration of the first stage of labour. The secondary outcomes were the duration of the second stage of labour, pain intensity, delivery mode, medication use, local swelling, fatigue, anxiety, satisfaction and neonatal outcomes. RESULTS: The experimental intervention reduced the duration of labour by 179 minutes (95% CI 146 to 213) in stage one and 19 minutes (95% CI 13 to 25) in stage two. It decreased pain by approximately 2 points (95% CI 2 to 2) on a 0-to-10 scale at 30, 60 and 90 minutes. It reduced the risk of a caesarean section (ARR 0.14, 95% CI 0.03 to 0.25; NNT 7, 95% CI 4 to 32) and vulvar swelling (ARR 0.11, 95% CI 0.03 to 0.19; NNT 9, 95% CI 5 to 31). It reduced fatigue by 18 points (95% CI 16 to 21) on a 15-to-75-point scale and anxiety by 9 points (95% CI 8 to 11) on an 18-to-72-point scale. Other effects were negligible or unclear. CONCLUSION: Active pelvic movements on a Swiss ball during labour reduced the duration of labour, pain intensity, and maternal fatigue and anxiety; they also lowered the risk of caesarean section and vulvar swelling. Several effects exceeded the smallest worthwhile effect. REGISTRATION: NCT04124835.

Effect of medication therapy management on discharged patient with Ulcerative Colitis with initial stage biotherapy: a randomized study

Purpose: The aim of this study was to explore the effects of medication therapy management in improving perception, medication adherence, and disease control in UC patients with first-stage of biotherapy. Subjects and Methods: A total of 120 patients with UC who received first-stage biotherapy participated in this study. The patients were divided into MTM group and CFU group. Both groups received three times follow-up, which were carried out at first, third, and sixth discharged month, Group A was followed with the MTM method, and Group B received conventional follow-up. MDRKT was used to assess patient perception, adherence to treatment was assessed by MMSA-8, and we also explored disease control and patient satisfaction. Results: A total of 116 patients completed the survey, the MTM group showed a significant improvement in perception, 84.2% of patients can correctly handle ADEs and 82.5% of patients knew what to do when they leak medication, 87.8% of patients in the MTM group had better adherence than 71.2% in the CPU group (P<0.05). The evaluation of disease control showed that 56.1% of patients in the Group A were in remission which was significantly higher than 32.2% in the Group B (P<0.05). Furthermore, the result of the questionnaire survey showed that perception, ADE, self-management, anxiety, and satisfaction were better in the MTM group than in the CPU group (P<0.05). Conclusion: The MTM group was effective in improving medication adherence, perception, and satisfaction in the patient with ulcerative colitis treated with first-stage biotherapy, and the disease control significantly improved (AU)

Long Cephalomedullary Nails Can Be a Cheap and Effective Interval Revision Prosthesis in Infected Hip Replacements That Require Proximal Femoral Replacement: A Small Case Series.

Hip prosthetic joint infection management is complex and expensive, especially in severe bone loss. Reducing the price of interval prosthesis when performing staged revision could minimize costs without compromising outcomes. We present 2 similar techniques developed independently that use an antibiotic-coated cephalomedullary nail with a total hip arthroplasty bearing (head and cemented acetabular component) attached to it as an interval proximal femoral replacement prosthesis. Using this technique, the femoral implant cost was reduced up to 10-fold. All patients have recovered well with resolution of infection and functional recovery similar to patients undergoing proximal femoral replacement. In one case, the lag screw (femoral neck) fractured at 5 months prompting the second-stage revision. This complication should be considered when deciding the timing of second-stage revisions in these cases.

Retrospective analysis of the application of percutaneous electrical nerve stimulation and meta-analysis.

After the stimulation of neurodermis, in the first stage, the relevant literature of each stage can be obtained through the relevant computer detection method. At the same time, also to the relevant database and scientific network research, and the influence of TENS tight comparison, the investigation is two years, using a series of score evaluation into the quality of the literature, in the process of inclusion if a certain funnel diagram analysis, the analysis results will be expressed according to the forest diagram, can get the final results in the review of many types of research, and then according to different types of research, delete the content of duplicate related reading topics. After reading the full text, if the content meets the inclusion criteria, it will show no significant difference between the effect of the control group and the pain effect of the experimental group, but the time of delivery is shorter than that of the control group, the pain intensity of TENS will decrease, thus shortening the labor time of each period.

Application of the Midi Parasep® SF technique for the detection of L1 larvae of Angiostrongylus cantonensis in faeces of infected rats.

We investigated parasitic zoonoses caused by protozoans and helminths in urban and peri-urban rat populations (Rattus norvegicus and R. rattus) in Spanish cities. Rats were trapped and then dissected to remove adult helminths, and the contents of the large intestine were retrieved for the study of parasitic forms. The Midi Parasep® solvent free (SF) technique was used to concentrate the parasites in the intestinal contents. Some of the rats studied (n = 8) were infected by the rat lungworm, Angiostongylus cantonensis, whose first stage larvae (L1) are shed in rat faeces. After the concentration technique, L1 larvae were found in the sediment of 6 of the 8 positive rats. The two negative sediment samples were due to the presence of either only adult females or, in addition to males, only young females in the lungs of the rats. In view of our results, Midi Parasep® SF turned out to be a simple, rapid, inexpensive, and sensitive method to detect nematode larvae, such as the L1 larvae of A. cantonensis (or A. costaricensis), in natural and experimentally infected rats.

Application value of analgesia throughout labor and analgesia during the first stage of labor in women with pregnancy-induced hypertension.

BACKGROUND: Effective analgesia is required to ensure maternal and neonatal safety. OBJECTIVE: To compare the therapeutic effects of analgesia applied throughout labor and analgesia applied during the first stage of labor in women with pregnancy-induced hypertension (PIH). METHODS: In this study, 120 puerperae with PIH who gave birth in our hospital were enrolled as the study participants and were randomized into two groups (n= 60 in each group) using a coin flip. Those who received analgesia throughout labor were enrolled in the observation group, and those administered analgesia during the first stage of labor were enrolled in the control group. The analgesic effects, changes in blood pressure during labor, and neonatal health were compared between the two groups. RESULTS: Differences in visual analog scale (VAS) scores before analgesia, 10 min after analgesia, and full cervical dilation between the two groups were not statistically significant (P> 0.05 in all). The VAS scores of the puerperae in the observation group during forced breathing in the second stage of labor and fetal head expulsion were lower than those in the control group (P< 0.05 for both). The incidence of postpartum hemorrhage, forceps delivery, and antihypertensive treatment in the observation group was slightly lower than in the control group, but the differences were not statistically significant (P> 0.05). The rate of oxytocin treatment in puerperae in the observation group was significantly lower than in the control group (P< 0.05). The differences in base excess, arterial partial pressure of oxygen, partial pressure of carbon dioxide, and pH between the two groups of newborns were not statistically significant (P> 0.05 for all). Differences in changes in systolic and diastolic blood pressure between the two groups of puerperae were not statistically significant (P> 0.05 for both). Eclampsia did not occur during labor in either group. CONCLUSION: For patients with PIH, the application of analgesia throughout labor had a positive analgesic effect, effectively controlling the changes in blood pressure and ensuring the health of newborns. This is worthy of widespread clinical application.

Hybrid First-stage Palliation and Other Strategies to Achieve Biventricular Repair in High-Risk Neonates With Complex Heart Anomalies and Aortic Arch Obstruction.

Medical and surgical advances have allowed single-stage total repair in neonates born with complex congenital heart anomalies and aortic arch obstruction. Nonetheless, total repair might be too complex or high risk in certain neonates with demographic, clinical or morphologic risk factors. Alternative management strategies might offer these neonates better outcomes with superior anatomic repair, shorter hospitalization, reduced morbidity, and improved survival. Alternative initial surgical strategies might include aortic arch repair and pulmonary artery band with or without cardiopulmonary bypass, extracardiac repair only and pulmonary artery band, Norwood operation, and hybrid first-stage palliation; all deferring complex biventricular intra-cardiac repair to later stage. The strategy choice should be personalized to each patient, taking into consideration the morphologic and clinical state, and the existent goals of care.

Effects of neuraxial analgesia technique on labor and maternal-fetal outcomes: a retrospective study.

PURPOSE: To compare the effects of epidural analgesia (EA) and combined spinal epidural analgesia (SEA) on labor and maternal-fetal outcomes. METHODS: We retrospectively identified and included 1499 patients with a single cephalic fetus who delivered at the study center from January 2015 to December 2018 and received neuraxial analgesia at the beginning of the active phase of labor (presence of regular painful contractions and cervical dilatation between 4 and 6 cm). Data including analgesia, labor characteristics, and maternal-fetal outcomes were retrieved from the prospectively collected delivery room database and medical records. RESULTS: SEA was associated with a shorter first stage of labor than EA, with a median difference of 60 min. On multivariable ordinal logistic regression analysis, neuraxial analgesia, gestational age, fetal weight, labor induction, and parity were independently associated with the first stage length: patients in the EA group were 1.32 times more likely to have a longer first stage of labor (95% CI 1.06-1.64, p = 0.012) than those in the SEA group. Additionally, a significantly lower incidence of fundal pressure was performed among patients who underwent SEA (OR 0.55, 95% CI 0.34-0.9, p = 0.017). No associations were observed between the used neuraxial analgesia technique and other outcomes. CONCLUSIONS: SEA was associated with a shorter length of the first stage of labor and a lower rate of fundal pressure use than EA. Further studies confirming the effects of SEA on labor management and clarifying differences in maternal-fetal outcomes will allow concluding about the superiority of one technique upon the other.

Obstetric outcomes after cervical loop electrosurgical excision procedure.

OBJECTIVES: This study aimed to investigate whether a history of loop electrosurgical excision procedure (i.e., conisation) affects obstetric and neonatal outcomes. METHODS: A retrospective cohort study was carried out in Västernorrland county, Sweden. 57 nulliparous women with singleton pregnancies and previous conisation were compared with 100 age-matched pregnant controls without history of conisation. RESULTS: There was significantly lower gestational age by delivery (p = 0.036), however, the premature delivery rate was not different. Caesarean section was also less frequent (OR: 0.29, 95% CI: 0.081-1.04, p = 0.047) in the conisation group than those in the control group. There were no differences in neonatal outcomes. CONCLUSIONS: Previous conisation does not affect the risk of prematurity or cervical dilatation during the first stage of labour. Women with history of conisation had a lower rate of caesarean section, and lower gestational age by delivery.

A Preliminary Study of Interdisciplinary Approach with a Single-Stage Surgery in Children with Cleft Lip and Palate.

A two-stage surgical procedure involving labioplasty and palatoplasty is a common surgical modality performed in children with cleft lip and palate. Additionally, an alveolar cleft bone graft is performed prior to the eruption of the canine teeth. These three surgeries impose the burden of general anesthesia separately for each procedure, and the formation of scar tissue from the procedure inhibits maxillary growth. We adopted a single-stage surgical procedure to overcome these drawbacks. To date, there have been no reports comparing the treatment outcomes of alveolar morphology and maxillary growth and development in children who underwent single-stage surgery with those who underwent two-stage surgery using plaster casts and cephalograms. Twenty children aged 5-7 years were equally divided into two groups based on whether they had undergone a two- or single-stage procedure. Cephalometric analysis and analysis of dentition models were conducted. The results showed that the single-stage surgery exhibited significant differences in the sella-nasion angle, point A to McNamara line, maxillary length, mandibular body length, and posterior arch width and length compared with the two-stage surgery. Therefore, it was suggested that the single-stage surgery had a favorable effect on maxillary growth compared with the two-stage surgery.

Adoption of Consensus Guidelines for Safe Prevention of the Primary Cesarean Delivery by Freestanding Birth Centers.

INTRODUCTION: Slow or arrested progress in labor is the most frequent (64%) indication for nonemergent transfer of laboring people from freestanding birth centers to the hospital. After the 2014 publication of the Consensus Statement on Safe Prevention of Primary Cesarean Delivery (Consensus Statement), many freestanding birth centers changed their clinical practice guidelines to allow more time for active labor in the birth center prior to hospital transfer. The result of these changes has not been evaluated in birth centers. Evaluation of adoption of guidelines based on the Consensus Statement in hospitals has shown inconsistent results. METHODS: Birth centers were contacted to determine whether they changed clinical practice guidelines in response to the Consensus Statement. A before-after analysis compared outcomes for the 2 calendar years before and the 2 calendar years after adoption of new guidelines with a retrospective analysis of deidentified client-level data collected in the American Association of Birth Centers Perinatal Data Registry. RESULTS: A third of responding birth centers (11 of 33) changed their clinical practice guidelines, mostly redefining the onset of active labor as beginning at 6 cm cervical dilatation and allowing 4 hours of arrest of dilatation in active labor before transfer to the hospital. These changes were associated with fewer diagnoses of prolonged first stage of labor (13.8% vs 8.0%, P < .01) but not with fewer intrapartum transfers (14.0% vs 14.7%, P = .55) or cesarean births (5.0 vs 4.1%, P = .26.) DISCUSSION: We found no evidence that making these practice changes was associated with better outcomes. Two hours of a lack of documented cervical change in active labor is likely long enough to diagnose arrested progress in labor. Research on proportion of morbidity and mortality associated with prolonged labor could inform practice guidelines for transfers.

Effect of Evening Primrose Vaginal Capsule on Cervix Preparation and Duration of First Stage of Labor in Nulliparous Women Referred to Fatemieh Hospital in Hamadan, Iran: A Single-blind Randomized Controlled Trial.

BACKGROUND: Cervix preparation is one of the main steps in the onset of labor and is very important for success in initiating or inducing labor. OBJECTIVE: The present study aimed at investigating the effect of evening primrose vaginal capsule on the preparation of cervix and the consequences of labor in nulliparous women. METHODS: This randomized clinical trial study was conducted in 2018 on 100 nulliparous women referred to Fatemieh Hospital in Hamadan. In intervention group (50 people), one evening primrose capsule (500 mg) was used vaginally and then two hours later, another capsule was used, and placebo was used in the control group (50 people). Then, the dilatation, effacement, Bishop scores and duration of the first stage of the labor were compared in two groups after 4 hours. Statistical analysis was performed with SPSS 21. The significance level was considered to be 0.05. RESULTS: There was a statistically significant difference in the mean score and standard deviation of dilatation, effacement of cervix, bi-shop scores and duration of the first stage of labor four hours after the intervention in the intervention and Placebo groups by controlling the effect of potential confounding factors (P <0.001). CONCLUSION: The results showed that the use of evening primrose vaginal capsules can reduce the length of the first stage of labor, improve Bishop score, and soften and ripen the cervix.

Constructing evidence-based clinical intrapartum care algorithms for decision-support tools.

AIM: To describe standardised iterative methods used by a multidisciplinary group to develop evidence-based clinical intrapartum care algorithms for the management of uneventful and complicated labours. POPULATION: Singleton, term pregnancies considered to be at low risk of developing complications at admission to the birthing facility. SETTING: Health facilities in low- and middle-income countries. SEARCH STRATEGY: Literature reviews were conducted to identify standardised methods for algorithm development and examples from other fields, and evidence and guidelines for intrapartum care. Searches for different algorithm topics were last updated between January and October 2020 and included a combination of terms such as 'labour', 'intrapartum', 'algorithms' and specific topic terms, using Cochrane Library and MEDLINE/PubMED, CINAHL, National Guidelines Clearinghouse and Google. CASE SCENARIOS: Nine algorithm topics were identified for monitoring and management of uncomplicated labour and childbirth, identification and management of abnormalities of fetal heart rate, liquor, uterine contractions, labour progress, maternal pulse and blood pressure, temperature, urine and complicated third stage of labour. Each topic included between two and four case scenarios covering most common deviations, severity of related complications or critical clinical outcomes. CONCLUSIONS: Intrapartum care algorithms provide a framework for monitoring women, and identifying and managing complications during labour and childbirth. These algorithms will support implementation of WHO recommendations and facilitate the development by stakeholders of evidence-based, up to date, paper-based or digital reminders and decision-support tools. The algorithms need to be field tested and may need to be adapted to specific contexts. TWEETABLE ABSTRACT: Evidence-based intrapartum care clinical algorithms for a safe and positive childbirth experience.

Uterovaginal prolapse in a primigravida presenting in active first stage of labor: a case report.

BACKGROUND: Uterovaginal prolapse is the descent of the uterus and vagina down the birth canal toward the introitus. The occurrence of uterovaginal prolapse in a primigravida is very rare. It can cause preterm labor, fetal demise, spontaneous abortion, postpartum hemorrhage, maternal urinary complications, sepsis, and death. This case report presents the rare occurrence of uterovaginal prolapse in a primigravida woman with no major risk factors identified for prolapse, who presented in active first stage of labor and delivered vaginally. CASE PRESENTATION: A 30-year-old Oromo primigravida woman who did not remember her last normal menstrual period but claimed amenorrhea of 9 months duration presented with the urge to bear down of 12 hours duration and passage of liquor of 8 hours duration. She was referred from the local health center to Jimma Medical Center with a diagnosis of prolonged labor. At presentation, she was in active first stage of labor with cervix 5-6 cm and fetal heartbeat was negative. She was followed for the progress of labor, and 4 hours after admission to the labor ward, she delivered a freshly dead male neonate weighing 3000 g. Her postpartum period was uneventful, and she was discharged on her third postpartum day and referred after 6 weeks to the outpatient department. CONCLUSION: Uterovaginal prolapse occurring in primigravida and during labor at first recognition is very rare, with congenital weakness being a possible underlying pathology. Management of uterovaginal prolapse during labor should be individualized on the basis of fetal condition and the severity of prolapse. For a patient with pelvic organ prolapse in labor, expectant management is a good option when there is no severe edema resulting in obstructed labor, as in our case, where the patient delivered vaginally and the prolapse resolved postpartum.

Labor interventions in low- and high-risk parturients in a university hospital

SUMMARY OBJECTIVE: The main aim of this study was to evaluate the impact of using interventions in low- and high-risk parturients on maternal and perinatal adverse outcomes during labor. METHODS: This is a prospective study. The analyzed variables were obtained through a questionnaire with puerperal women (between 1- and 48-h postpartum) and through medical record searches. The study population was divided into two groups as follows: Group I included parturients who underwent at least one type of obstetric intervention and Group II included parturients who did not undergo any type of obstetric intervention. RESULTS: Most parturients (75.3%) underwent at least one type of intervention, with oxytocin being the most prevalent intervention (49.5%), followed by misoprostol use (28.7%), elective cesarean section at the request of the patient (23.0%), amniotomy (21.2%), and episiotomy (21.0%). Regarding the adverse perinatal outcomes related to low-risk pregnancies, the prevalence of the second- or third-degree perineal tears (17.8% vs. 36.7%, p=0.001) was lower in Group I than in Group II. Moreover, in high-risk pregnancies, the prevalence of hospitalization in the neonatal intensive care unit (2.8% vs. 16.7%, p<0.001), adult intensive care unit admission (0.8% vs. 3.9%, p=0.004), and the need for oxygen therapy (26.8% vs. 40.4%, p<0.001) was lower in Group I than in Group II. CONCLUSIONS: In low-risk parturients, the interventions performed were associated with lower prevalence of second- or third-degree perineal tears. There was a lower prevalence of neonatal and adult intensive care unit admissions, the need for oxygen therapy, intracranial hemorrhage, and neonatal infection among high-risk parturients.
