Abstract
OBJECTIVE This study aimed to systematically review the worldwide second-stage cesarean delivery rate concerning pre-second-stage cesarean delivery and assisted vaginal birth rates. DATA SOURCES PubMed, Medline Ovid, EBSCOhost, Embase, Scopus, and Google Scholar were queried from inception to February 2023, with the following terms: "full dilatation," "second stage," and "cesarean," with their word variations. Furthermore, an additional cohort of 353,434 cases from our recently published study was included. STUDY ELIGIBILITY CRITERIA Only original studies that provided sufficient information on the number of pre-second-stage cesarean deliveries, second-stage cesarean deliveries, and vaginal births were included for the calculation of different modes of delivery. Systemic reviews, meta-analyses, or case reports were excluded. METHODS Study identification and data extraction were independently performed by 2 authors. Selected studies were categorized on the basis of parity, study period, and geographic regions for comparison. RESULTS A total of 25 studies were included. The overall pre-second-stage cesarean delivery rate, the second-stage cesarean delivery rate, and the second-stage cesarean delivery-to-assisted vaginal birth ratio were 17.94%, 2.65%, and 0.19, respectively. Only 5 studies described singleton, term, cephalic presenting pregnancies of nulliparous women, and their second-stage cesarean delivery rates were significantly higher than those studies with cohorts of all parity groups (4.50% vs 0.83%; P<.05). In addition, the second-stage cesarean delivery rate showed a secular increase across 2009 (0.70% vs 1.05%; P<.05). Moreover, it was the highest among African studies (5.14%) but the lowest among studies from East Asia and South Asia (0.94%). The distributions of second-stage cesarean delivery rates of individual studies and subgroups were shown with that of pre-second-stage cesarean delivery and assisted vaginal birth using the bubble chart. CONCLUSION The overall worldwide pre-second-stage cesarean delivery rate was 17.94%, the second-stage cesarean delivery rate was 2.65%, and the second-stage cesarean delivery-to-assisted vaginal birth ratio was 0.19. The African studies had the highest second-stage cesarean delivery rate (5.14%) and second-stage cesarean delivery-to-assisted vaginal birth ratio (1.88), whereas the studies from East Asia and South Asia were opposite (0.94% and 0.11, respectively).

Medicine (Baltimore) 2023; 102:e35200. [PMID: 37746982 PMCID: PMC10519505 DOI: 10.1097/md.0000000000035200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 08/02/2023] [Accepted: 08/23/2023] [Indexed: 09/26/2023] Open
Abstract
This study was conducted to explore the influencing factors of gastrointestinal function recovery after cesarean section (CS), which could provide a reference for the enhanced recovery after surgery in obstetrics. This is a cross-sectional survey on Chinese mothers receiving CS. The participants's socio-demographic characteristics, perioperative diet, medical condition and gastrointestinal function after surgery were collected by a self-designed questionnaire. Binary logistic regression analysis was employed to explore the influencing factors of gastrointestinal function recovery after CS. A total of 1501 (94.76%) valid questionnaires were collected. The first borborygmus was 2.21 ± 0.63 hours, and the first anal exhaust was 35.73 ± 14.85 hours after the CS. The incidence of abdominal distension and intestinal obstruction were 15.1% and 0.7%, respectively. The parity, type of CS, 2-hours bleeding after surgery, time of first meal after surgery, whether taking peppermint water after surgery were the independent influencing factors for gastrointestinal function recovery after CS. We should pay more attention to the mothers with scarred uterus, manage the labor process strictly, and reduce 2-hours bleeding after surgery. The mothers with CS should also be encouraged to eat early and take peppermint water to promote intestinal peristalsis actively.

Exploring factors influencing skin incision to the delivery time and their impact on neonatal outcomes among emergency cesarean deliveries indicated for non-reassured fetal heart rate status. Front Pediatr 2023; 11:1224508. [PMID: 37808561 PMCID: PMC10551621 DOI: 10.3389/fped.2023.1224508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 08/21/2023] [Indexed: 10/10/2023] Open
Abstract
Background The time interval between skin incision and delivery (S-D) is crucial in determining neonatal outcome; however, little is known about the influencing factors and their impact on neonatal outcomes, particularly among emergency cesarean deliveries (ECD) indicated for fetal distress. This study investigated the factors influencing S-D time and their effects on neonatal outcomes among mothers who underwent ECD for non-reassured fetal heart rate status. Methods This retrospective cohort study involved 426 mother-infant pairs over four years. We retrieved data from the medical records, including baseline characteristics, perioperative data, and neonatal outcomes. Using multivariable logistic regression analysis, adjusted odd ratios, and a 95% confidence interval, potential factors influencing S-D time and their impacts on neonatal outcomes were assessed. A p-value of less than 0.05 was considered statistically significant. Results Factors independently associated with longer S-D time (>8 min) were mothers who had previous CD (AOR 5.9: 95% CI 2.2-16.1), obese mothers (AOR 6.2: 95% CI 1.6-24.5), and the second stage of labor (AOR 5.3: 95% CI 2.4-11.7). Adverse neonatal outcomes, including a 5th minute Apgar score of less than 7, the need for NICU admission, and neonatal death, were significantly higher in the longer S-D time interval [47.7% vs. 8.9%; p-value 0.001], [21.9% vs. 9.1%; p-value 0.001], and [32% vs. 11.8%; p-value = 0.004], respectively. Obese mothers and the second stage of labor, but not previous CD, adversely impact neonatal outcomes. Conclusion Longer S-D times are significantly associated with adverse neonatal outcomes. Factors that prolong the time interval between skin incision and delivery may or may not necessarily be associated with adverse neonatal outcomes. Considering surgical techniques that shorten the incision-delivery time and preparation for advanced neonatal care for risky subjects would help reduce detrimental neonatal consequences.

Abstract
Background Cesarean section (CS) involves the delivery of the fetus through incisions in the abdomen or uterine walls which is an alternative to vaginal delivery. In the majority of women, second-stage CS is performed without even attempting assisted vaginal delivery. This leads to difficulty for obstetricians for whether to perform an immediate CS or attempt a difficult vaginal birth as the effective method of delivery as CS are linked with higher morbidities which further increase when a CS is performed in the second stage. Hence, the present study was performed to find out obstetrics results in women undergoing second-stage CS. Method A cross-sectional study was conducted in the Department of Obstetrics and Gynecology of a tertiary care center attached to a medical college to study obstetric outcomes in women undergoing second-stage CS from January 2021 to December 2022 on 54 postnatal women who underwent second-stage CS. Results The mean age was 26.7 ± 3.9 years ranging between 19 and 35 years involving a majority of primiparity women. Maximum patients were having gestational age between 39 and 40 weeks and had spontaneous labor. The main indication of second-stage CS was non-reassuring fetal status and the method of delivery mainly involved for the deeply impacted head was the modified patwardhan technique in which if the head is embedded deeply in the pelvis in the OP position the anterior shoulder is delivered first followed by the same side leg then opposite side leg followed by the arm is gently delivered. Baby's trunk, legs, and buttocks are moved out by pulling them carefully and gently. And lastly, the head of the infant is finally moved out. The intra-operative complications mainly found were an extension of uterine angle and the post-operative complication was post-partum hemorrhage (PPH). The most common neonatal complication was the requirement for neonatal intensive care unit (NICU) admission. In conclusion, the present study reported a hospital range between seven and 14 days in comparison to other studies that reported hospital stays between three and 15 days. Conclusion In conclusion, higher maternal and fetal morbidities were associated with CS performed at full dilation of the cervix. The most common maternal complication seen was an injury to uterine vessels along with PPH however neonatal complications included the requirement of NICU monitoring. As there are no appropriate guidelines for the same, formulation of guidelines for performing CS at full dilation is required.

Abstract
INTRODUCTION Unsuccessful operative vaginal delivery (OVD) is associated with high rates of materno-fetal morbidity. We aimed to examine institutional rates of unsuccessful OVDs (uOVD) and compare them with successful OVD (sOVD) in order to identify factors to aid patient selection and education. METHODS A 6-month retrospective cohort study was performed on all unsuccessful and successful OVDs in a tertiary level maternity hospital in the Republic of Ireland. Maternal demographics and obstetric factors were assessed to evaluate potential underlying risk factors for unsuccessful operative vaginal delivery versus successful vaginal delivery. RESULTS There were 4,191 births during the study period with an OVD rate of 14.2% (n = 595) with 28 (4.7% of OVDs) being unsuccessful. Unsuccessful OVD were predominately nulliparous (25; 89.2%) with a mean maternal age of 30.1 years (range 20-42), with more than half (n = 15, 53.5%) being induced. The most common indication for induction was prolonged rupture of membranes (PROM) (n = 7, 25%) which was significantly different from the successful OVD group. A senior obstetrician was significantly more likely to be the primary operator in uOVD when compared to sOVD. (82.1 % V 54.1% p < 0.01). The majority of unsuccessful OVD were vacuum deliveries (n = 17; 60.7%), with a significantly higher mean birthweight when compared to successful OVD (3.695 kg V 3.483 kg; p < 0.01). Following an unsuccessful OVD, women were more likely to have a postpartum haemorrhage (64.2 % V 31.5% p < 0.01) and their infant was more likely to require admission to the neonatal intensive care unit (NICU) (32.1 % V 5.8% p < 0.01) when compared with successful OVD. CONCLUSION Risk factors for unsuccessful OVD were higher birth weight and induction of labour. There was a higher incidence of postpartum haemorrhage and NICU admission when compared with successful OVD.

Abstract
OBJECTIVE To synthesise the evidence from studies that implemented interventions to increase/reintroduce the use of assisted vaginal births (AVB). DESIGN Systematic review. ELIGIBILITY CRITERIA We included experimental, semi-experimental and observational studies that reported any intervention to reintroduce/increase AVB use. DATA SOURCES We searched PubMed, EMBASE, CINAHL, LILACS, Scopus, Cochrane, WHO Library, Web of Science, ClinicalTrials.gov and WHO.int/ictrp through September 2021. RISK OF BIAS For trials, we used the Cochrane Effective Practice and Organisation of Care tool; for other designs we used Risk of Bias for Non-Randomised Studies of Interventions. DATA EXTRACTION AND SYNTHESIS Due to heterogeneity in interventions, we did not conduct meta-analyses. We present data descriptively, grouping studies according to settings: high-income countries (HICs) or low/middle-income countries (LMICs). We classified direction of intervention effects as (a) statistically significant increase or decrease, (b) no statistically significant change or (c) statistical significance not reported in primary study. We provide qualitative syntheses of the main barriers and enablers for success of the intervention. RESULTS We included 16 studies (10 from LMICs), mostly of low or moderate methodological quality, which described interventions with various components (eg, didactic sessions, simulation, hands-on training, guidelines, audit/feedback). All HICs studies described isolated initiatives to increase AVB use; 9/10 LMIC studies tested initiatives to increase AVB use as part of larger multicomponent interventions to improve maternal/perinatal healthcare. No study assessed women's views or designed interventions using behavioural theories. Overall, interventions were less successful in LMICs than in HICs. Increase in AVB use was not associated with significant increase in adverse maternal or perinatal outcomes. The main barriers to the successful implementation of the initiatives were related to staff and hospital environment. CONCLUSIONS There is insufficient evidence to indicate which intervention, or combination of interventions, is more effective to safely increase AVB use. More research is needed, especially in LMICs, including studies that design interventions taking into account theories of behaviour change. PROSPERO REGISTRATION NUMBER CRD42020215224.

Abstract
OBJECTIVE To investigate the mode of delivery and birth outcomes in relation to the duration of the passive second stage of labour in nulliparous women. METHODS AND FINDINGS A retrospective cohort study of all nulliparous women (n = 1131) at two delivery units in Sweden. Maternal and obstetric data were obtained from electronic medical records during 2019. The passive second stage was defined as the complete dilation of the cervix until the start of the active second stage. The duration of the passive second stage was categorized into three groups: 0 to 119 min (0 to <2 h), 120-239 min (2- <4h) and ≥240 min (≥4h). Differences between the groups were examined using t-test and Chi2-tests and regression analyses were used to analyse adjusted odds ratio with 95% confidence intervals. The primary outcome was mode of delivery in relation to the duration of the passive second stage and the secondary outcomes covered a series of adverse maternal and neonatal birth outcomes. The rates of instrumental and caesarean deliveries increased as the duration of the passive second stage increased. A ≥4-hour duration of the passive second stage was associated with a nine-times increased risk of caesarean section, and a four-times risk of instrumental delivery compared to a duration of <2 hours in the adjusted analyses. No differences were found in the maternal birth outcomes. The risk of a 5-minute Apgar score <7 was increased in the 2-<4h group. A longer passive second stage was not associated with an increased risk of negative birth experience. CONCLUSIONS Our study demonstrates an increased risk of operative delivery for a longer duration (>2h) of the passive second stage in nulliparous women, although most of the women gave birth by spontaneous vaginal delivery even after ≥4 hours. There was no evidence of an increased risk of adverse maternal outcomes in a longer duration of the passive second stage but there were indications of increased adverse neonatal outcomes. Assessment of fetal well-being is important when the duration of the passive phase is prolonged.

Abstract
INTRODUCTION This study examined the prevalence of and risk factors for a prolonged passive second stage of labor in nulliparous women. MATERIAL AND METHODS This was a historical cohort study of all nulliparous women (n = 1131) at two delivery units in Sweden. Maternal and obstetric data were obtained from electronic medical records during 2019. Duration of the passive second stage was measured as time from retracted cervix to start of pushing. Prolonged passive second stage was defined as ≥2 h. Prevalence was calculated and associations between prolonged passive second stage and maternal, obstetric and neonatal characteristics and potential risk factors were assessed using logistic regression models. RESULTS The prevalence of prolonged passive second stage was 37.6%. Factors associated with an increased risk of prolonged passive second stage were epidural analgesia (adjusted odds ratio [aOR] 3.93; 95% confidence interval [CI] 2.90-5.34), malpresentation (aOR 2.26; 95% CI 1.27-4.05), maternal age ≥ 30 years (aOR 2.00; 95% CI 1.50-2.65) and birthweight ≥ 4 kg (aOR 1.50; 95% CI 1.05-2.15). Maternal body mass index ≥30 (aOR 0.52; 95% CI 0.34-0.79) and noncohabiting (aOR 0.51; 95% CI 0.30-0.89) reduced the odds of prolonged passive second stage. CONCLUSIONS A prolonged passive second stage of labor in nulliparous women is common (n = 425 [38%]). We found epidural analgesia, malpresentation, maternal age ≥ 30 years and birthweight ≥4 kg to be major risk factors associated with an increased risk of a prolonged passive second stage. Birth outcomes for prolonged passive second stage need to be investigated to strengthen evidence for the management of the second stage of labor.

Abstract
Background Caesarian sections (CS) are life-saving management for a pregnant mother and fetus subject to obstetric complications. The World Health Organization (WHO) expected CS rates not to exceed 10 to 15 per 100 live births in any country. This study aimed to assess the prevalence of CS and its associated factors from the 2016 Nepal Demographic and Health Survey (NDHS), building on previous studies mentioned in detail in the latter part of the paper. Methods This study analyzed the secondary data from the 2016 Nepal Demographic and Health Survey (NDHS), conducted from June 19, 2016, to January 31, 2017. The survey is undertaken every five years; consequently, the data capture the information in the previous five years from the data collection period. We used the 2016 NDHS, which is implemented by the new Enumeration Area (EA) under the support of the Ministry of Health (MOH) and funded by the U.S. Agency for International Development (USAID). In the rural areas, the sample is stratified and selected in two stages. In the first stage, wards are selected as the primary sampling units (PSU), with households subsequently chosen from the PSUs. In the urban areas, the sample is nominated in three stages. In the first stage, wards are selected as PSUs; in the second stage, one EA is chosen from each PSU, and finally, households are selected from the EAs. Then data were collected from the women in the reproductive age group within the selected households. Results The prevalence of CS in Nepal conforms to the WHO standard with 7.8, 7.5, and 8.1 per 100 deliveries, or 9.8, 8.9, and 9.1 per women's last births in the previous one, three, and five years, respectively. Older mothers of 30 years old or more, having high incomes, being overweight and obese, using the internet, ante-natal care (ANC) visits of more than four times, ANC by doctors, twin delivery, and having babies of 4 kg or more, had higher odds for a CS while having two or more children seemed to be protective towards CS. Conclusion These findings can be used to update health policies surrounding CS delivery to limit unnecessary CS and ensure better health as CS is not without complications.

Ramotsababa M, Setlhare V. Late registration for antenatal care by pregnant women with previous history of caesarean section. Afr J Prim Health Care Fam Med 2021; 13:e1-e9. [PMID: 34082552 PMCID: PMC8182559 DOI: 10.4102/phcfm.v13i1.2776] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 03/19/2021] [Accepted: 03/23/2021] [Indexed: 11/22/2022] Open
Abstract
Background Despite good access to antenatal care (ANC) services for most women, and regular training of healthcare workers in obstetrics and gynaecology, many pregnant women with a previous history of caesarean section (C/S) still presented late for ANC services at Letsholathebe II Memorial Hospital (LIIMH) in Maun, Botswana. This may increase morbidity and mortality in women with previous C/S delivery and neonates. Knowing why women with previous C/S present late for ANC may help in the formulation of interventions that decrease morbidity and mortality amongst these women and neonates. Aim The aim of this study was to explore the reasons why pregnant women with a previous history of C/S registered late for ANC, at LIIMH. Setting This study was performed at LIIMH, a district hospital situated in Maun, Botswana. Methods This was a descriptive qualitative study. Consenting pregnant women with previous C/S who presented at LIIMH after the 20 weeks of pregnancy were interviewed until data saturation. The data was analysed for themes. Results The reasons for late registration at LIIMH include lack of information, misconception on the appropriate booking time and venue, dissatisfaction with the quality of ANC clinic services, use of alternative ANC providers, delayed referral, and pregnancy experience. Conclusion Lack of knowledge of ANC delivery venue, using alternative ANC providers, and dissatisfaction with ANC clinic services, contributed to late registration. Pregnant women with previous history of C/S should be informed about ANC, delivery plans, and the assistance of alternative ANC providers should be explored.

Concerned topics of epidural labor analgesia: labor elongation and maternal pyrexia: a systematic review. Chin Med J (Engl) 2020; 133:597-605. [PMID: 32032081 PMCID: PMC7065870 DOI: 10.1097/cm9.0000000000000646] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/31/2022] Open
Abstract
Objective: Labor is a complex process and labor pain presents challenges for analgesia. Epidural analgesia (EA) has a well-known analgesic effect and is commonly used during labor. This review summarized frequently encountered and controversial problems surrounding EA during labor, including the labor process and maternal intrapartum fever, to build knowledge in this area. Data sources: We searched for relevant articles published up to 2019 in PubMed using a range of search terms (eg, “labor pain,” “epidural,” “analgesia,” “labor process,” “maternal pyrexia,” “intrapartum fever”). Study selection: The search returned 835 articles, including randomized control trials, retrospective cohort studies, observational studies, and reviews. The articles were screened by title, abstract, and then full-text, with a sample independently screened by two authors. Thirty-eight articles were included in our final analysis; 20 articles concerned the labor process and 18 reported on maternal pyrexia during EA. Results: Four classic prospective studies including 14,326 participants compared early and delayed initiation of EA by the incidence of cesarean delivery. Early initiation following an analgesia request was preferred. However, it was controversial whether continuous use of EA in the second stage of labor induced adverse maternal and neonatal outcomes due to changes in analgesic and epidural infusion regimens. There was a high incidence of maternal pyrexia in women receiving EA and women with placental inflammation or histologic chorioamnionitis compared with those receiving systemic opioids. Conclusions: Early EA (cervical dilation ≥1 cm) does not increase the risk for cesarean section. Continuous epidural application of low doses of analgesics and programmed intermittent epidural bolus do not prolong second-stage labor duration or impact maternal and neonatal outcomes. The association between EA and maternal pyrexia remains controversial, but pyrexia is more common with EA than without. A non-infectious inflammatory process is an accepted mechanism of epidural-related maternal fever.

Relation between Length of Exposure to Epidural Analgesia during Labour and Birth Mode. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16162928. [PMID: 31443209 PMCID: PMC6720813 DOI: 10.3390/ijerph16162928] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 08/02/2019] [Accepted: 08/09/2019] [Indexed: 12/17/2022]
Abstract
Objective: To appraise the relationship between the length of exposure to epidural analgesia and the risk of non-spontaneous birth, and to identify additional risk factors. This study is framed within the MidconBirth project. Study design: A multicentre prospective study was conducted between July 2016 and November 2017 in three maternity hospitals in different Spanish regions. The independent variable of the study was the length of exposure to epidural analgesia, and the dependent variable was the type of birth in women with uncomplicated pregnancies. The data was analyzed separately by parity. A multivariate logistic regression was performed. The odds ratios (OR), using 95% confidence intervals (CI) were constructed. Main outcome measures: During the study period, 807 eligible women gave birth. Non-spontaneous births occurred in 29.37% of the sample, and 75.59% received oxytocin for augmentation of labour. The mean exposure length to epidural analgesia when non-spontaneous birth happened was 8.05 for primiparous and 6.32 for multiparous women (5.98 and 3.37 in spontaneous birth, respectively). A logistic regression showed the length of exposure to epidural during labour was the major predictor for non-spontaneous births in primiparous and multiparous women followed by use of oxytocin (multiparous group). Conclusions: The length of exposure to epidural analgesia during labour is associated with non-spontaneous births in our study. It highlights the need for practice change through the development of clinical guidelines, training programs for professionals and the continuity of midwifery care in order to support women to cope with labour pain using less invasive forms of analgesia. Women also need to be provided with evidence-based information.

Ali J, Hebbar S. Ultrasound Assessment of Foetal Head-Perineum Distance Prior to Induction of Labour as a Predictor of Successful Vaginal Delivery. J Obstet Gynaecol India 2019; 69:129-135.

Abstract
Background In modern obstetrical practice, incidence of induction of labour is on rise for varied maternal and foetal indications. Ultrasound can help obstetricians in counselling patients before induction of labour and explain the probability of successful induction. Objectives To study the role of foetal head-perineum distance in predicting successful vaginal delivery and to correlate with other parameters such as cervical length and Bishop score. Design This study is a prospective case-control study in a tertiary care teaching hospital. Population There were 250 term patients between 37 and 40+ weeks with singleton cephalic presentation with no contraindications for vaginal delivery. Methods Prior to induction of labour, transperineal ultrasound was performed to measure foetal head-perineum distance. Simultaneously, cervical length was performed using transvaginal ultrasound probe. Bishop score was determined at the same time by clinical examination. Main Outcome Measures Outcome of induction was considered successful when it resulted in vaginal delivery. It was considered to be a failure if patient did not get into active phase of labour or an operative intervention had to be performed because of non-progress of labour in active phase of labour. Cases were excluded if caesarean delivery had to be performed in the event of foetal distress. Results It was observed that as the transperineal foetal head-perineum distance decreased, the rate of vaginal delivery increased. Similarly, when foetal head-perineum distance increased, the rate of caesarean delivery increased. At a cut-off ≤ 5.5 cm, foetal head-perineum distance had a maximum predictability (sensitivity 97%, specificity 88.1%). Conclusion Transperineal foetal head-distance measured by ultrasound can be used as an important tool to predict vaginal delivery before induction of labour.

On the variation in maternal birth canal in vivo viscoelastic properties and their effect on the predicted length of active second stage and levator ani tears. J Biomech 2018; 74:64-71. [PMID: 29731323 DOI: 10.1016/j.jbiomech.2018.04.019] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Revised: 03/29/2018] [Accepted: 04/14/2018] [Indexed: 12/23/2022]
Abstract
The pubovisceral muscles (PVM) help form the distal maternal birth canal. It is not known why 13% of vaginal deliveries end in PVM tears, so insights are needed to better prevent them because their sequelae can lead to pelvic organ prolapse later in life. In this paper we provide the first quantification of the variation in in vivo viscoelastic properties of the intact distal birth canal in healthy nulliparous women using Fung's Quasilinear Viscoelastic Theory and a secondary analysis of data from a clinical trial of constant force birth canal dilation to 8 cm diameter in the first stage of labor in 26 nullipara. We hypothesized that no significant inter-individual variation would be found in the long time constant, τ2, which characterizes how long it takes the birth canal to be dilated by the fetal head. That hypothesis was rejected because τ2 values ranged 20-fold above and below the median value. These data were input to a biomechanical model to calculate how such variations affect the predicted length of the active second stage of labor as well as PVM tear risk. The results show there was a 100-fold change in the predicted length of active second stage for the shortest and longest τ2 values, with a noticeable increase for τ2 values over 1000 s. The correlation coefficent between predicted and observed second stage durations was 0.51. We conclude that τ2 is a strong theoretical contributor to the time a mother has to push in order to deliver a fetal head larger than her birth canal, and a weak predictor of PVM tear risk.
