Abstract
OBJECTIVES Epidural-related maternal fever increases the incidence of Category II fetal tracings. To compare the effectiveness of low-flow oxygen inhalation and cooling treatment for parturients with Category II fetal tracings caused by epidural-related maternal fever. METHODS We investigated 200 pregnant women who accepted epidural analgesia during labor and had body temperature exceeding 38 °C during labor. Among the patients, 99 and 101 were randomly allocated to receive cooling treatment group (control group) and oxygen inhalation (oxygen group), respectively. The primary outcome was the incidence of Category II fetal heart rate tracings. RESULTS The incidence of Category II fetal heart rate tracings in the control group was significantly higher than that in the oxygen group. However, no significant differences were noted between the two groups in terms of the Apgar scores; amniotic fluid turbidity; or maternal outcomes, including cesarean section rate, forceps delivery rate, lateral resection rate, manual removal of placenta rate, the amount of intrapartum hemorrhage, and hemorrhage at postpartum 2 h. Oxygen inhalation therapy was more effective than cooling treatment in reducing the incidence of Category II tracings. CONCLUSION Low-flow and short-term oxygen inhalation for parturients with epidural-related maternal fever reduces the incidence of Category II fetal heart rate tracings, but had no significant influence on the mode of delivery or neonatal outcomes.

Abstract
Fever during childbirth, which is often observed in clinical settings, is characterized by a temperature of 38°C or higher, and can occur due to infectious and non-infectious causes. A significant proportion of non-infectious causes are associated with epidural-related maternal fever during vaginal delivery. Therapeutic interventions are required because fever has adverse effects on both mother and newborn. Effective treatment options for ERMF are lacking. As it is difficult to distinguish it from intrauterine infections such as chorioamnionitis, antibiotic administration remains the only viable option. We mentioned the importance of interleukin-1 receptor antagonist in the sterile inflammatory fever pathway and the hormonal influence on temperature regulation during childbirth, an important factor in elucidating the pathophysiology of ERMF. This review spotlighted the etiology and management of ERMF, underscoring recent advancements in our understanding of hypothalamic involvement in thermoregulation and its link to sterile inflammation. We propose to deepen the understanding of ERMF within the broader context of autonomic neuroscience, aiming to foster the development of targeted therapies.

Clinical chorioamnionitis at term: definition, pathogenesis, microbiology, diagnosis, and treatment. Am J Obstet Gynecol 2024; 230:S807-S840. [PMID: 38233317 DOI: 10.1016/j.ajog.2023.02.002] [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: 01/06/2023] [Revised: 01/31/2023] [Accepted: 02/02/2023] [Indexed: 04/05/2023]
Abstract
Clinical chorioamnionitis, the most common infection-related diagnosis in labor and delivery units, is an antecedent of puerperal infection and neonatal sepsis. The condition is suspected when intrapartum fever is associated with two other maternal and fetal signs of local or systemic inflammation (eg, maternal tachycardia, uterine tenderness, maternal leukocytosis, malodorous vaginal discharge or amniotic fluid, and fetal tachycardia). Clinical chorioamnionitis is a syndrome caused by intraamniotic infection, sterile intraamniotic inflammation (inflammation without bacteria), or systemic maternal inflammation induced by epidural analgesia. In cases of uncertainty, a definitive diagnosis can be made by analyzing amniotic fluid with methods to detect bacteria (Gram stain, culture, or microbial nucleic acid) and inflammation (white blood cell count, glucose concentration, interleukin-6, interleukin-8, matrix metalloproteinase-8). The most common microorganisms are Ureaplasma species, and polymicrobial infections occur in 70% of cases. The fetal attack rate is low, and the rate of positive neonatal blood cultures ranges between 0.2% and 4%. Intrapartum antibiotic administration is the standard treatment to reduce neonatal sepsis. Treatment with ampicillin and gentamicin have been recommended by professional societies, although other antibiotic regimens, eg, cephalosporins, have been used. Given the importance of Ureaplasma species as a cause of intraamniotic infection, consideration needs to be given to the administration of antimicrobial agents effective against these microorganisms such as azithromycin or clarithromycin. We have used the combination of ceftriaxone, clarithromycin, and metronidazole, which has been shown to eradicate intraamniotic infection with microbiologic studies. Routine testing of neonates born to affected mothers for genital mycoplasmas could improve the detection of neonatal sepsis. Clinical chorioamnionitis is associated with decreased uterine activity, failure to progress in labor, and postpartum hemorrhage; however, clinical chorioamnionitis by itself is not an indication for cesarean delivery. Oxytocin is often administered for labor augmentation, and it is prudent to have uterotonic agents at hand to manage postpartum hemorrhage. Infants born to mothers with clinical chorioamnionitis near term are at risk for early-onset neonatal sepsis and for long-term disability such as cerebral palsy. A frontier is the noninvasive assessment of amniotic fluid to diagnose intraamniotic inflammation with a transcervical amniotic fluid collector and a rapid bedside test for IL-8 for patients with ruptured membranes. This approach promises to improve diagnostic accuracy and to provide a basis for antimicrobial administration.

Abstract
BACKGROUND The management and nursing care of women's temperature during delivery is an important part of clinical obstetrics. We aimed to evaluate maternal intrapartum fever during epidural labour analgesia to provide evidence for the management and care of women in labour. METHODS This study was conducted and reported according to the STROBE statement. Women in labour undergoing epidural labour analgesia in our hospital from 1 January 2021 to 31 August 2022 were retrospectively selected. The characteristics of women in labour with and without intrapartum fever were compared. Pearson correlation and logistic regression analysis were used to analyse the influencing factors of postpartum fever. RESULTS A total of 196 women in labour were included, the incidence of maternal intrapartum fever in women in labour undergoing epidural analgesia was 27.5%. Pearson correlation analyses showed that BMI, oxytocin use, labour duration, number of vaginal examinations, time from rupture of the foetal membranes to the end of labour and duration of epidural analgesia were all correlated with the occurrence of intrapartum fever (all P < 0.05). Logistic regression analyses indicated that body mass index ≥28 kg/m2 (OR = 1.825), oxytocin use (OR = 2.082), labour duration ≥9.2 h (OR = 2.613), number of vaginal examinations ≥8 (OR = 2.044-3.115), the time from rupture of the foetal membranes to the end of labour ≥250 min (OR = 2.766) and duration of epidural analgesia ≥300 min (OR = 3.106) were risk factors for intrapartum fever in women in labour undergoing epidural analgesia (all P < 0.05). CONCLUSIONS Maternal intrapartum fever in women in labour undergoing epidural analgesia is common and influenced by many factors. Nurses should take early preventive care measures according to these factors during epidural analgesia in labour.

Am J Obstet Gynecol 2023; 229:540.e1-540.e9. [PMID: 38051599 DOI: 10.1016/j.ajog.2023.05.013] [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: 02/14/2023] [Revised: 05/15/2023] [Accepted: 05/15/2023] [Indexed: 12/07/2023]
Abstract
BACKGROUND Clinical chorioamnionitis refers to the presence of maternal fever (≥38°C) and at least 2 clinical signs: (1) maternal tachycardia (>100 bpm), (2) fetal tachycardia (>160 bpm), (3) maternal leukocytosis >15,000/mm2, (4) purulent vaginal discharge, and (5) uterine tenderness. Few data exist to guide the appropriate management of women with isolated intrapartum fever in the absence of other clinical signs suggesting chorioamnionitis. OBJECTIVE This study compared maternal and neonatal infectious outcomes and microbiological outcomes between women with isolated intrapartum fever and women with clinical chorioamnionitis. STUDY DESIGN This 10-year retrospective study included all the laboring women at our institution, at ≥34 weeks of gestation, with a singleton pregnancy and body temperature of ≥38.0°C, with or without other evidences of infection. According to our department protocol, women with isolated intrapartum fever received intravenous ampicillin, whereas women with clinical chorioamnionitis received intravenous ampicillin plus gentamicin. The primary outcome was puerperal endometritis, compared between women with isolated intrapartum fever (treated with ampicillin) and women with clinical chorioamnionitis (treated with ampicillin plus gentamicin). The secondary maternal outcomes consisted of (1) maternal clinical outcomes, such as cesarean delivery, surgical site infection, postpartum hemorrhage, and postpartum length of stay, and (2) microbiological studies, including positive chorioamniotic membrane swabs and blood culture. Among the secondary neonatal outcomes were early-onset sepsis, neonatal intensive care unit admission, and length of stay. Of note, 2 multivariate logistic regression models were created. A model aimed to predict puerperal endometritis controlled for gestational age of >41 weeks, diabetes mellitus, obesity, positive group B streptococcus status, rupture of membrane ≥18 hours, meconium staining, positive chorioamniotic membrane swabs, cesarean delivery, and empiric postdelivery antibiotic administration. A model aimed to predict neonatal early-onset sepsis controlled for gestational age of 34 to 37 weeks, positive group B streptococcus status, rupture of membrane ≥18 hours, and positive chorioamniotic membrane swabs. RESULTS Overall, 458 women met the inclusion criteria. Compared with women with clinical chorioamnionitis (n=231), women with isolated intrapartum fever (n=227) had higher rates of puerperal endometritis (3.9% vs 8.8%; P=.03), early-onset sepsis (0.4% vs 4.4%; P=.005), positive chorioamniotic membrane swabs (46.3% vs 63.9%; P<.001), and ampicillin-resistant Escherichia coli (35.5% vs 48.9%; P=.033). The rate of group B streptococcus-positive chorioamniotic membrane swabs was similar between the groups. In a subanalysis of women with negative or unknown group B streptococcus status, the puerperal endometritis and neonatal early-onset sepsis rates were higher among women with isolated intrapartum fever than women with suspected chorioamnionitis (8.7% vs 3.3% [P=.041] and 4.1% vs 0% [P<.001], respectively). In 2 multivariate analysis models, among women with isolated intrapartum fever treated with ampicillin compared with those with clinical chorioamnionitis treated with ampicillin and gentamicin, the odds ratio of antibiotic treatment of endometritis was 2.65 (95% confidence interval, 1.06-6.62; P=.036), and the odds ratio of neonatal early-onset sepsis was 8.33 (95% confidence interval, 1.04-60.60; P=.045). CONCLUSION Women with intrapartum fever, with or without other signs of infection, were at increased risk of maternal and neonatal complications. The use of ampicillin as a sole agent in isolated intrapartum fever might promote ampicillin-resistant E coli growth in the chorioamniotic membranes and consequently lead to puerperal endometritis and early-onset sepsis. In this context, a broad-range antibiotic should be considered.

Abstract
BACKGROUND The underlying mechanism of epidural-related maternal fever (ERMF) is not fully understood. This systematic review aimed to identify factors associated with ERMF in low-risk, full-term women using neuraxial analgesia. METHODS PubMed, Embase, Web of Science, CENTRAL, and Wanfang Data were searched from inception to September 10, 2022 with no language restriction. Studies reported descriptive data regarding the factors associated with ERMF. A random effects model meta-analysis was used to pool the raw data of univariate analyses for each identified factor. Sensitivity and subgroup analyses were performed to explore possible sources of heterogeneity. RESULTS Eighteen observational studies involving 33 427 women were included, with 18 factors eligible for meta-analyses. Higher body mass index, baseline temperature, admission maternal interleukin-6 levels and white blood cell counts, nulliparity, increasing gestational age, longer duration of labor and rupture of membranes, increasing number of vaginal examinations, oxytocin use, higher birth weight, lower cervical dilation at initiation of analgesia, and longer analgesia duration were associated with increased risk of ERMF, while intermittent compared with continuous epidural dosing was associated with a decreased risk of ERMF (odds ratio 0.25, 95% CI 0.16 to 0.48, P < 0.001). However, heterogeneity among studies was high and the quality of evidence was low for these meta-analyses, except for intermittent epidural dosing. CONCLUSIONS Many factors are associated with ERMF but may not be independent or causal. Further study is needed to clarify the interactions of these factors in ERMF development and whether modification of these factors might influence risk of ERMF.

Abstract
Introduction This study aimed to explore the relationship between neuraxial labor analgesia and intrapartum fever and to demonstrate the influence of maternal fever on perinatal outcomes within 6 weeks after birth. Methods This was a secondary analysis of a multicenter prospective cohort study that enrolled women with single- and full-term cephalic pregnancy in northern China. Intrapartum maternal fever was defined as the highest axillary temperature during labor ≥37.5°C. Data on baseline characteristics, maternal variables, and neonatal outcomes were all collected. The association between neuraxial labor analgesia and intrapartum maternal fever was analyzed with logistic regression models, and the cutoff point was identified by the receiver operating characteristic curve. Results Of 577 parturients, 74 (12.8%) developed intrapartum fever. Neuraxial analgesia was associated with an increased risk of maternal intrapartum fever with or without adjusting for confounding factors (adjusted OR = 2.68; 95% CI: 1.32-5.47; p = 0.007). Further analysis showed that neuraxial analgesia of <5 h did not increase the risk of intrapartum fever compared with no analgesia (OR = 1.52; 95% CI: 0.63-3.64; p = 0.35), and longer neuraxial labor analgesia time (over 5 h) significantly increased the risk of fever (OR = 3.38; 95% CI: 1.63-7.01; p = 0.001). Parturients with intrapartum fever suffered more maternal adverse outcomes compared with those without fever (p < 0.001). Neonates of women with intrapartum fever had slightly higher rates of composite adverse neonatal outcomes compared with those without fever; however, the difference was not statistically significant (p = 0.098). Conclusion In women with low-risk pregnancies, a longer time of neuraxial labor analgesia was associated with an increased risk of intrapartum maternal fever. Intrapartum fever was related to adverse maternal outcomes but did not significantly affect neonatal outcomes within 6 weeks after delivery.

Abstract
Intrapartum fever is common and presents diagnostic and treatment dilemmas for the clinician. True maternal sepsis is rare; only an estimated 1.4% of women with clinical chorioamnionitis at term develop severe sepsis. However, the combination of inflammation and hyperthermia adversely impacts uterine contractility and, in turn, increases the risk for cesarean delivery and postpartum hemorrhage by 2- to 3-fold. For the neonate, the rates of encephalopathy or the need for therapeutic hypothermia have been reported to be higher with a maternal fever >39°C when compared with a temperature of 38°C to 39°C (1.1 vs 4.4%; P<.01). In a large cohort study, the combination of intrapartum fever and fetal acidosis was particularly detrimental. This suggests that intrapartum fever may lower the threshold for fetal hypoxic brain injury. Because fetal hypoxia is often difficult to predict or prevent, every effort should be made to reduce the risk for intrapartum fever. The duration of exposure to epidural analgesia and the length of labor in unmedicated women remain significant risk factors for intrapartum fever. Therefore, paying careful attention to maintaining labor progress can potentially reduce the rates of intrapartum fever and the risk for cesarean delivery if fever does occur. A recent, double-blind randomized trial of nulliparas at >36 weeks' gestation demonstrated that a high-dose oxytocin regimen (6×6 mU/min) when compared with a low-dose oxytocin regimen (2×2 mU/min) led to clinically meaningful reductions in the rate of intrapartum fever (10.4% vs 15.6%; risk rate, 0.67; 95% confidence interval, 0.48-0.92). When fever does occur, antibiotic treatment should be initiated promptly; acetaminophen may not be effective in reducing the maternal temperature. There is no evidence that reducing the duration of fetal exposure to intrapartum fever prevents known adverse neonatal outcomes. Therefore, intrapartum fever is not an indication for cesarean delivery to interrupt labor with the purpose of improving neonatal outcome. Finally, clinicians should be ready for the increased risk for postpartum hemorrhage and have uterotonic agents on hand at delivery to prevent delays in treatment.

Abstract
Sepsis is a severe affection, that requires an urgent and specific treatment sequence. Physiological changes occurring during pregnancy make the diagnosis of sepsis more challenging in this setting, with possible delay in treatment initiation, that in turn is responsible for poorer maternal and fetal outcome. This review aims to summarize current knowledge on the diagnosis and treatment of maternal sepsis, as well as persistent knowledge gaps in the field.

Abstract
We aimed to explore the association between epidural-related maternal fever (ERMF) and prognosis of parturients. 159 parturients who underwent vaginal delivery under labor epidural analgesia (LEA) received noninvasive continuous core body temperature monitoring. 122 of them completed the 42-day postpartum follow-up. Parturients with body temperature ≥38°C during labor were categorized as the Fever group, while the others were categorized as the No-Fever group. Compared to No-Fever group, Fever group had a greater proportion of primiparas, greater gestational age of parturients, and longer third stage of labor. The cesarean section and forceps delivery rates, and the amount of intrapartum hemorrhage in Fever group were significantly higher. There were no significant between-group differences with respect to puerperal infection, and amniotic fluid turbidity degree, neither significant between-group difference at 42-days postpartum. We found that ERMF was associated with some short-term outcomes. However, it showed no relation with long-term prognosis of the parturients at 42-days postpartum.

Abstract
Abstract
Background
Labor epidural analgesia has been suggested to be associated with intrapartum fever. We designed this study to investigate the effects of epidural analgesia and combined spinal-epidural analgesia on maternal intrapartum temperature.
Methods
Four hundred healthy nullipara patients were randomly assigned to receive either epidural analgesia (EA group) or combined spinal-epidural analgesia (CSEA group). Maternal temperature was measured hourly after analgesia administration. The primary outcome was the incidence of maternal fever, and the secondary outcomes were the duration of analgesia, analgesia to full cervical dilation and analgesia to delivery. Neonatal outcomes and other basic labor events were also recorded.
Results
Maternal temperature gradually increased with time in both analgesia groups during labor. However, the CSEA group had a lower incidence of maternal fever, and a lower mean maternal temperature at 5 h, 6 h, and 9 h after analgesia. In addtion, the CSEA group also had a shorter time of analgesia duration, analgesia to full cervical dilation, analgesia to delivery, and less dose of epidural local anesthetic than the EA group.
Conclusion
Our findings suggest that combined spinal-epidural analgesia is associated with a lower risk of intrapartum fever than epidural analgesia.

Abstract
Background Intrapartum fever is a well-known predisposing factor for severe perinatal outcomes. Herein, we explored the intrapartum features, obstetric outcomes, and neonatal outcomes in relation to the extent of intrapartum fever via three group analyses. Methods A retrospective cohort analysis consisting of 575 term, singleton live births in one medical center from January 1st to December 31st, 2020 was carried out. Parturients who had experienced a maximal intrapartum fever of <38.0 °C were compared with two sub-groups of parturients who had experienced respective maximal fevers of 38.0-38.9 °C and ≥39.0 °C. We computed the adjusted risks for adverse perinatal outcomes via multiple logistic regression models to control for confounders. Results There were statistically remarkable differences among the three groups in 13 items including body mass index, epidural, and WBC before delivery (p < 0.05). In contrast with intrapartum fevers of 37.5-37.9 °C, intrapartum fevers of 38.0-38.9 °C were linked to an elevated risk of neonatal sepsis and neonatal intensive care unit admission with an odds ratio (OR) of 4.28 (95% CI 2.162-8.479) and 1.73 (95% CI 1.125-2.666), nonetheless, the relationship was remarkably higher for intrapartum fever ≥39.0 °C, with an OR of 6.40 (95% CI 2.450-16.725) and 2.23 (95% CI 1.021-4.854). Additionally, intrapartum fevers of 38.0-38.9 °C and ≥39.0 °C were related to remarkably higher risk for operative deliveries (OR 2.24, 95% CI 1.373-3.648; OR 3.59, 95% CI 1.398-9.226; respectively) and histological chorioamnionitis (OR 3.77, 95% CI 2.261-6.271; OR 19.24, 95% CI 7.385-50.111, respectively). Conclusions Intrapartum fever is an important indicator of adverse perinatal outcomes. The higher the temperature, the higher risk of histological chorioamnionitis, as well as the risk of neonatal sepsis and neonatal intensive care unit admission.

Abstract
BACKGROUND All newborn infants are required to undergo the Apgar score/assessment immediately after birth and again at five minutes. This vital examination is performed to determine how well the infant is adjusting to the birthing process and the outside environment. Some newborns may have a normal Apgar score, while others may have a low score. The purpose of this study was to identify factors associated with low Apgar scores among newborns at an intermediate hospital in Northern Namibia. OBJECTIVE To identify maternal factors associated with an immediate low Apgar score in newborns at an intermediate hospital in Northern Namibia and to examine the association between maternal factors and an immediate low Apgar score. Quantitative, retrospective, descriptive research methodology was employed. A document review checklist was utilized to collect data at Onandjokwe Intermediate Hospital between August 2020 and October 2020. RESULTS Gravidity (p0.021), parity (p0.029), haemoglobin after the first ante-natal care visit (p0.011), ante-partum haemorrhage (APH) (p0.004), membrane status (p0.000), duration of labour (p0.000), type of delivery (p0.000), and caesarean section type and indication (p0.000) were found to be associated with an immediate low Apgar score. CONCLUSIONS The study identified maternal factors that influence an infant's initial low Apgar score. Strengthen maternal health education regarding gravidity and parity, diet, and recognizing danger signs during pregnancy. In addition, strict monitoring of patients with a partograph, cardiotocography, accurate record keeping, and prompt referral of patients with risk factors is strongly advised.

Abstract
Background Both epidural and combined spinal-epidural (EA and CSEA) analgesia can induce intrapartum maternal fever. CSEA has a more rapid onset and wider nerve block than EA. Therefore, CSEA might have a different profile of intrapartum maternal fever, including higher temperatures or earlier occurrence. This randomized clinical trial was to determine whether CSEA could cause maternal fever earlier than EA. Methods A randomized, double-blind, controlled clinical trial was performed on 233 nulliparous full-term pregnant women during vaginal delivery. The pregnant women were randomly allocated into the EA group (n = 113) and the CSEA group (n = 120). The fever latent period, from analgesia start to fever occurrence, was the primary endpoint in this study. The temperature was measured every 30 min using an eardrum thermometer during labor analgesia. The fever was defined as an eardrum temperature of ≥38 °C. Results No difference was found in the maternal fever rate between the EA and the CSEA groups (10/113 vs. 7/120, P = 0.356). There was no significant difference in the fever latent period between the two groups (4.75 ± 0.86 h vs. 3.79 ± 2.2 h, p = 0.305). The temperatures at all points had no differences between EA and CSEA. Conclusion CSEA had a similar latent fever period as EA. A further study is warranted to confirm the similar characteristic between CSEA and EA in the development of intrapartum maternal fever.

Abstract
Many populations experience high seasonal temperatures. Pregnant women are considered vulnerable to extreme heat because ambient heat exposure has been linked to pregnancy complications including preterm birth and low birthweight. The physiological mechanisms that underpin these associations are poorly understood. We reviewed the existing research evidence to clarify the mechanisms that lead to adverse pregnancy outcomes in order to inform public health actions. A multi-disciplinary expert group met to review the existing evidence base and formulate a consensus regarding the physiological mechanisms that mediate the effect of high ambient temperature on pregnancy. A literature search was conducted in advance of the meeting to identify existing hypotheses and develop a series of questions and themes for discussion. Numerous hypotheses have been generated based on animal models and limited observational studies. There is growing evidence that pregnant women are able to appropriately thermoregulate; however, when exposed to extreme heat, there are a number of processes that may occur which could harm the mother or fetus including a reduction in placental blood flow, dehydration, and an inflammatory response that may trigger preterm birth. There is a lack of substantial evidence regarding the processes that cause heat exposure to harm pregnant women. Research is urgently needed to identify what causes the adverse outcomes in pregnancy related to high ambient temperatures so that the impact of climate change on pregnant women can be mitigated.

Abstract
BACKGROUND Procalcitonin is an established biomarker for bacterial sepsis in the nonpregnant population with better diagnostic and prognostic value for bacterial infections. OBJECTIVE This study aimed to evaluate whether procalcitonin levels could be used in the diagnosis and management of intrapartum sepsis in women and their neonates suspected of intrapartum bacterial sepsis. STUDY DESIGN A prospective observational cohort study was conducted at the University Hospitals of Bristol and Weston NHS Foundation Trust. Overall, 117 women and their neonates managed for suspected intrapartum sepsis from June 2020 to October 2020 were included. Procalcitonin levels were measured in addition to routine biomarkers white cell count and C-reactive protein in women and their neonates during the initial septic screen and follow-up blood samples. The placentas underwent detailed histopathology. Maternal and neonatal parameters were used to categorize cases into “high-suspicion bacterial sepsis,” “equivocal bacterial sepsis,” and “low-suspicion bacterial sepsis.” The Kruskal-Wallis test was used to compare categories with biomarker values and placental histology scores. RESULTS Procalcitonin level was increased in 6 women in the initial septic screen sample, compared with 100 women with an increased C-reactive protein level. There was a significant difference in maternal postnatal procalcitonin results between “high-suspicion bacterial sepsis” and “low-suspicion bacterial sepsis” categories (P=.004). Moreover, 71.2% of placentas showed varying degrees of chorioamnionitis. CONCLUSION In our cohort of women, 94.6% had normal procalcitonin levels while in labor at the time of the septic screen, consistent with the low number of confirmed bacteremia. The result provided a basis that procalcitonin may complement clinical judgment and interpretation of already used prognostic and diagnostic tests, improving patient care in the management of intrapartum sepsis.

Abstract
STUDY OBJECTIVE To assess whether pulse perfusion index (PI) values could be employed to predict intrapartum fever and to provide a cut-off PI value for predicting intrapartum fever occurrence. DESIGN We conducted a single-center, prospective, observational study. SETTING Delivery room at the Department of Obstetrics, Affiliated Hospital of Jiangsu University. PATIENTS 117 parturients who intended to have a vaginal delivery. INTERVENTIONS Each parturient received epidural analgesia. MEASUREMENTS We checked each parturient's tympanic temperature before analgesia (T0), at 1 h (T1) and 2 h (T2) after analgesia, immediately at the end of the second (T3) and third (T4) stages of labor, and at 1 h postpartum (T5). A temperature of ≥38°C was defined as fever. PI, measured on the right second toe, was recorded before analgesia (PI0) and at 10 min (PI10), 20 min (PI20), and 30 min (PI30) after analgesia. The PI change rate was calculated as the incremental change in PI30 from PI0, divided by the PI0. Receiver operating characteristic (ROC) curves were used to verify the utility of the PI30 and PI change rate values for predicting intrapartum fever. MAIN RESULTS We found that peak temperature (TP) occurred at the end of the second or the third stage of labor. Within 30 min after analgesia, the PI showed a significant increase over time and there was a linear correlation between PI30 and TP values (P < 0.001, r = 0.544). The PI10, PI20, PI30 and PI change rate in febrile parturients were higher than those in afebrile parturients (P < 0.001). The area under the ROC (AUROC) for PI30 was 0.818 (P < 0.001) with a cut-off of 9.30. The AUROC of the PI change rate was 0.738 (P < 0.001) with a cut-off of 3.45. CONCLUSIONS PI30 and PI change rate values could be used to predict intrapartum fever in parturients after epidural analgesia.

Abstract
Background Chorioamnionitis (CA) affects up to 3.9% of all deliveries worldwide and is one of the leading causes of early-onset neonatal sepsis. Fever≥380C is an essential criterion for the diagnosis of clinical CA. Obstetricians frequently take the maternal risk factors into consideration, and many mothers are treated as CA even with peak intrapartum temperature (PIT) between 37.60C to 37.90C if they have other clinical signs and risk factors. Aim To estimate the prevalence of confirmed chorioamnionitis and adverse neonatal outcomes among those mothers with PIT below 380C. Materials and methods Retrospective chart review among mothers delivered at Al-Wakra Hospital, Qatar, between1stJanuary2016 to 31stDecember 2019 with a clinical suspicion of CA. Results Among 21,471 mothers, 442 were suspected of having CA (2.06%, 95% CI 1.88 to 2.26%). After exclusions, 415 were included in the study, 203(48.9%) mothers had PIT between 37.6-37.90C. There was no significant difference in the rate of confirmed CA between the low (<380C) and higher (≥380C) temperature groups (25.4%Vs.31.3%, OR0.75, 95%CI0.46-1.25 , p.262). More patients in the low-temperature group received paracetamol for PIT between 37.6 to 37.9 0C, while it was less frequently used for such milder elevation in higher temperature group (88.2%Vs.38.9%, OR11.69, 95% CI 6.46-2.15, p <.001). Conclusion The incidence of suspected clinical CA in our institution was within the international rates. Although nearly half of the mothers with suspected clinical CA had peak temperature below the recommended diagnostic criteria, the rate of confirmed CA and neonatal outcome was not significantly different from those with PIT≥380C. Early antipyretic use might have affected further elevation of temperature. Supplementary Information The online version contains supplementary material available at 10.1186/s12887-022-03239-9.

Abstract
PURPOSE To investigate the effect of different concentrations of ropivacaine on maternal temperature and inflammatory factors during epidural analgesia. METHOD One hundred and forty healthy term nulliparas were randomly assigned to receive epidural analgesia with either 0.1% ropivacaine (group H) or 0.068% ropivacaine (group L). Epidural sufentanil 0.3 μg/ml was added in both groups. Maternal tympanic temperature was measured at initiation of epidural analgesia (baseline temperature) and each hour thereafter. Maternal blood samples were taken at the time of epidural placement and 4 hours after analgesia to detect IL-6 and IL-1β serum concentrations. Visual analog scale pain scores, labour events and neonatal outcomes were recorded. RESULTS Epidural analgesia using 0.1% or 0.068% ropivacaine both achieved satisfactory pain relief. Increases in maternal body temperature and in IL-6 levels were observed in both groups, but there was no significant difference between the two groups. The incidence of maternal fever was similar between the two groups. CONCLUSION Maternal body temperature and serum inflammatory factors are similarly affected by 0.1% or 0.068% ropivacaine used during epidural analgesia use for labour pain relief.

Am J Obstet Gynecol MFM 2021; 4:100539. [PMID: 34861429 DOI: 10.1016/j.ajogmf.2021.100539] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 11/16/2021] [Accepted: 11/23/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Both infectious and noninfectious causes of maternal fever have been linked to adverse neonatal outcomes including low Apg0ar scores, respiratory distress, hypotonia, and neonatal seizures. Even in the absence of infection, the occurrence of intrapartum fever is a strong risk factor for poor long-term neonatal developmental outcomes, including encephalopathy, cerebral palsy, and neonatal death. OBJECTIVE The primary objective of this study was to compare intrapartum and postpartum maternal and fetal umbilical cord serum levels of cytokines RANTES, interferon-ɣ, interleukin-1β, interleukin-2, interleukin-4, interleukin-6, interleukin-8, interleukin-10, interleukin-13, and tumor necrosis factor-α among nonfebrile patients, febrile patients without clinical chorioamnionitis, and febrile patient with clinical chorioamnionitis. STUDY DESIGN This study was conducted at the Richmond University Medical Center from May 15, 2020 to July 16, 2019. During this time, we recruited 30 nonfebrile patients at >36 gestational weeks who were in labor and collected umbilical cord and pre- and postdelivery maternal serum samples to evaluate the cytokine levels. Placentas were collected for pathologic review and to evaluate the histopathologic findings. These results were compared with 121 patients who developed a fever of >38°C during labor. The febrile patients were further divided based on the presence or absence of clinical chorioamnionitis. A secondary analysis was performed based on the presence of absence of histologic chorioamnionitis. Statistical analysis was performed using IBM Statistical Package for the Social Sciences version 25.0. For the 3 group comparisons, a P value of <.017 was considered statistically significant after application of a Bonferroni correction. RESULTS A total of 151 patients were included in the study; 30 were nonfebrile patients, 46 were febrile patients with a diagnosis of clinical chorioamnionitis, and 75 were febrile patients without clinical chorioamnionitis. Compared with nonfebrile patients, umbilical cord serum interferon-ɣ, interleukin-1β, interleukin-6, interleukin-8, RANTES, and tumor necrosis factor-α levels were elevated in the presence of maternal hyperthermia irrespective of the diagnosis of clinical chorioamnionitis. Interleukin-6 umbilical cord levels were more than doubled from 63.60 pg/mL (6.09-1769.03 pg/mL) in febrile patients with no clinical chorioamnionitis to 135.77 pg/mL (1.86-6004.78 pg/mL) in febrile patients with clinical chorioamnionitis, making it the only cytokine that was significantly different between these 2 groups. When comparing the intrapartum maternal serum, we found a significant elevation in the interleukin-10, RANTES, and tumor necrosis factor-α levels in the febrile group irrespective of the presence of clinical chorioamnionitis when compared with the nonfebrile group. In the postpartum maternal blood evaluations, tumor necrosis factor-α was the only cytokine that was significantly higher in febrile patients than in nonfebrile controls. CONCLUSION In the setting of intrapartum fever, maternal cytokine profiles were similar irrespective of the diagnosis of clinical chorioamnionitis. Even in the absence of clinical or histologic chorioamnionitis, maternal hyperthermia induced elevations in fetal cytokines.

Abstract
Background Maternal intrapartum fever has a serious impact on mother and child. However, the corresponding study seems to be in short. Methods The role of inflammatory cells in patients who were diagnosed with intrapartum fever lived in part of Eastern China was evaluated. The obstetrics outcomes, complete blood cell count (CBC) and thereby converted neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio, monocyte to lymphocyte ratio (MLR), and vaginal secretion were compared in different groups. Results Prepartum values of white blood cell (WBC), red blood cell (RBC), and hemoglobin (Hb) were all a little higher in the febrile group than in the afebrile group, and postpartum WBC in the afebrile group was still higher while postpartum RBC and Hb were inferior to non‐fever maternity. Postpartum NLR and MLR were all higher in the fever group but not preferred overtly difference before delivery. Additionally, the comparison of WBC, RBC, Hb, platelets, neutrophils, and monocytes in prepartum and postpartum all showed significant differences. Conclusion The parturition could bring about the value change of CBC and intrapartum fever might aggravate or alleviate this change. Besides, the intrapartum fever might not be caused mainly by infection and the difference between bacteria and fungus could reflect in the CBC.

Abstract
BACKGROUND Conflicting statements by stakeholders in obstetric care have suggested different criteria for defining peripartum fever and suspected intraamniotic infection, which have not been evaluated. METHODS A case-control study of pregnancies between 35 and 41 weeks at a single tertiary care center between January 2016 and December 2017. Cases with pathology-confirmed chorioamnionitis were identified, and demographic data, risk factors, and neonatal outcomes were extracted from the medical record. The American College of Gynecology (ACOG) and National Institutes of Health (NIH) Workshop guidelines for identifying isolated maternal fever and suspected intraamniotic infection were applied, retrospectively. Odds ratios, sensitivity/specificity, and predictive value of each guideline for pathology-confirmed chorioamnionitis and for secondary outcomes of interest were determined. RESULTS 943 mother-infant dyads were evaluated including 41 (4.3%) with pathology-confirmed chorioamnionitis. Among cases, 18 (43.9%) experienced any maternal temperature ≥38°C (100.4°F) with 12 (29.2%) and 8 (19.5%) cases meeting criteria for isolated maternal fever according to the ACOG and Workshop guidelines, respectively. Furthermore, the ACOG and Workshop guidelines correctly identified 6 (14.6%) and 3 (7.3%) of cases of pathology-confirmed chorioamnionitis with high agreement between definitions (κ = 0.63). Laboratory evaluation, antimicrobial exposure, and prolonged length of stay in offspring are substantially higher in cases as compared to controls. CONCLUSIONS Guidelines that rely on maternal fever definitions for the diagnosis of suspected intraamniotic infection exhibit high agreement with low sensitivity, but high specificity and negative predictive value for pathology-confirmed chorioamnionitis. Maternal temperature ≥38°C continues to drive clinical decision-making for both mother and offspring.

Abstract
Objective To explore the risk factors for intrapartum fever and to develop a nomogram to predict the incidence of intrapartum fever. Methods The general demographic characteristics and perinatal factors of 696 parturients who underwent vaginal birth at the Affiliated Hospital of Xuzhou Medical University from May 2019 to April 2020 were retrospectively analysed. Data was collected from May 2019 to October 2019 on 487 pregnant women who formed a training cohort. A multivariate logistic regression model was used to identify the independent risk factors associated with intrapartum fever during vaginal birth, and a nomogram was developed to predict the occurrence. To verify the nomogram, data was collected from January 2020 to April in 2020 from 209 pregnant women who formed a validation cohort. Results The incidence of intrapartum fever in the training cohort was found in 72 of the 487 parturients (14.8%), and the incidence of intrapartum fever in the validation cohort was 31 of the 209 parturients (14.8%). Multivariate logistic regression analysis showed that the following factors were significantly related to intrapartum fever: primiparas (odds ratio [OR] 2.43; 95% confidence interval [CI] 1.15–5.15), epidural labour analgesia (OR 2.89; 95% CI 1.23–6.82), premature rupture of membranes (OR 2.37; 95% CI 1.13–4.95), second stage of labour ≥ 120 min (OR 4.36; 95% CI 1.42–13.41), amniotic fluid pollution degree III (OR 10.39; 95% CI 3.30–32.73), and foetal weight ≥ 4000 g (OR 7.49; 95% CI 2.12–26.54). Based on clinical experience and previous studies, the duration of epidural labour analgesia also appeared to be a meaningful factor for intrapartum fever; therefore, these seven variables were used to develop a nomogram to predict intrapartum fever in parturients. The nomogram achieved a good area under the ROC curve of 0.86 and 0.81 in the training and in the validation cohorts, respectively. Additionally, the nomogram had a well-fitted calibration curve, which also showed excellent diagnostic performance. Conclusion We constructed a model to predict the occurrence of fever during childbirth and developed an accessible nomogram to help doctors assess the risk of fever during childbirth. Such assessment may be helpful in implementing reasonable treatment measures. Trial registration Clinical Trial Registration: (www.chictr.org.cnChiCTR2000035593)

Abstract
This review summarizes recent evidences regarding the potential influences of epidural labor analgesia (ELA) on the outcomes of neonates and children. Terms and relevant words including “ELA,” “ELA and neonatal outcomes,” “ELA and children's development,” and “ELA and children's neurocognitive development” were used to search articles published in PubMed database up to October 2019. Original articles and reviews regarding potential influences of ELA on neonates and children were identified. Relevant references of the selected articles were also screened. The anesthetics used during ELA can be absorbed, enter the fetus, and produce neonatal depression; however, these effects are less severe than those during systematic opioid analgesia. The impact of anesthetic exposure during ELA on children's neurodevelopment has not been fully studied, but would be mild if any. ELA increases the risk of intrapartum maternal fever; the latter may be harmful to neonatal outcomes. The use of ELA may increase birth injury by increasing instrumental delivery, although long-term adverse events are rare. On the other hand, ELA may reduce maternal depression and, thus, produce favorable effects on neurocognitive development in childhood; but evidences are still lacking in this aspect. ELA may produce both favorable and unfavorable effects on neonates and children. These effects should be discussed with parturient women before making decisions. The potential harmful effects should be carefully managed. The overall impacts of ELA on neonatal and children's outcomes need to be studied further.

Abstract
OBJECTIVE To evaluate the impact of prolonged exposure to meconium-stained amniotic fluid (MSAF), in women with term pre-labor spontaneous rupture of membranes (PROM), on pregnancy outcome. METHODS A retrospective cohort study of women who gave birth in a single university-affiliated tertiary medical center (2011-2019). Eligibility was limited to singleton pregnancies at term who presented with PROM. Women with MSAF were immediately induced and were compared to low-risk pregnant women with clear amniotic fluid (CAF) at admission who underwent induction of labor 24 h after rupture of membranes. All women were stratified into 4-time frame groups from rupture of membranes to delivery: T0: 0-7 h, T1: 8-13 h, T2: 14-18 h, and T3: > 18 h for the MSAF group. The time frames for the CAF were: T0 - 24-31 h, T1: 32-38 h, T2: 40-44 h, and T3: > 44 h. The maternal adverse composite outcome included any of the following: intrapartum fever (IPF), prolonged second stage (PSS), need for manual removal of suspected retained placenta, postpartum hemorrhage, and readmission within 45 days after delivery. The adverse composite neonatal outcome included one or more of the following: meconium aspiration syndrome, neonatal asphyxia, need for respiratory support, and intracranial hemorrhage. RESULTS Overall, 1631 women met the inclusion criteria (536 in the MSAF and 1095 in the CAF group). Both groups showed a gradual decrease in the rate of vaginal delivery over time, the vaginal delivery rate in the MSAF group was 75.7% at T0 in comparison to 61.6% at T3 (p < .001). In the CAF group, the vaginal delivery rate was 84.5% at T0 in comparison to 68.8% at T3 (p < .001). This decrease was in concomitance with an increase in the rates of prolonged second-stage and intrapartum fever. There were no significant differences in the rates of postpartum hemorrhage, suspected retained placenta, or readmission within 45 days between women with either MSAF or CAF. There was a significant gradual increase in the adverse composite neonatal outcome in the MSAF group (1.9% at T0, 5.2% at T1, 6.0% at T2, and 8.2% at T3. p = .038). No similar increase was found in the CAF group (2.5% at T0, 4.1% at T1, 2.6% at T2, and 4.1% at T3. p = .449). CONCLUSION Prolonged rupture of membranes in the presence of meconium does not affect maternal outcomes, however, prolonged exposure to meconium lead to an increased adverse neonatal outcome.

Abstract
AIM To use continuous real-time monitoring of maternal core body temperature during labor and investigate the association between epidural analgesia, intrapartum maternal fever, and maternal and neonatal outcomes. METHODS Among 201 pregnant women attending our institution for a vaginal in-hospital delivery, 159 women received epidural analgesia and 42 women did not receive epidural analgesia. Women's core body temperature was continuously monitored for the duration of labor using a smartphone/iPad-connected wireless thermometer positioned in an axilla. The primary outcome was a change in maternal core body temperature during labor. Among women receiving epidural analgesia, maternal and neonatal outcomes were compared in women who developed an intrapartum fever and those who had no intrapartum temperature elevation. RESULTS Of the women receiving epidural analgesia, 26.4% (n = 42/159) developed intrapartum fever ≥38 °C compared to 7.1% (n = 3/42) of women not receiving epidural analgesia. Among those receiving epidural analgesia, women who developed intrapartum fever had a significantly longer first stage of labor and a higher incidence of cesarean section, assisted vaginal delivery, intrapartum hemorrhage, and turbid amniotic fluid compared to women with no intrapartum temperature elevation. Neonates of women who developed intrapartum fever had lower 1- and 5-min Apgar scores compared to neonates of women with no intrapartum temperature elevation; however, the difference was not significant. CONCLUSION This study used a precise and accurate method to monitor core body temperature among women receiving epidural analgesia. Results showed that the use of epidural analgesia during labor was associated with intrapartum maternal fever in all stages of labor. Fever after epidural analgesia was associated with adverse maternal outcomes, independent of neonatal complications.

Abstract
OBJECTIVE To compare the cesarean section rate before and after the introduction of an expectant management protocol in patients with abnormally progressing first-stage labor. METHODS A prospective monocentric cohort study performed between January 2012 and July 2016. RESULTS 267 patients were included, 97 in the control group and 170 in the study group. The number of cesarean sections decreased from 86 % to 45 % (p < 0.001). The number of instrumental extractions increased from 8.3% to 29.4% (p < 0.001). The number of postpartum hemorrhages increased from 5.2% to 18% (p < 0.01). No differences in the rates of perineal lesions, neonatal pHa below 7.10, and shoulder dystocia were observed. CONCLUSION The expectant management in patients with labor arrest in the first stage was associated with a decrease in the number of cesarean sections, at the cost of an increase in instrumental extractions and postpartum hemorrhages.

J Obstet Gynaecol Res 2021; 47:1153-1163. [PMID: 33438353 DOI: 10.1111/jog.14651] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Revised: 11/25/2020] [Accepted: 12/25/2020] [Indexed: 12/24/2022]
Abstract
AIM Previous studies analyzing intrapartum fever by dichotomization of fever just above 38.0°C or not may lead to overlook clinical significance of borderline fever. We aimed to investigate the maternal baseline and intrapartum characteristics, neonatal outcomes, and inflammatory placental pathology in relation to the degree of intrapartum fever by three group analysis. METHODS We performed a retrospective analysis of consecutive singleton deliveries between 370/7 to 410/7 weeks divided into three groups based on the peak body temperature during labor: No fever (< 37.5°C), borderline fever (≥ 37.5°C and < 38.0°C), and overt fever (≥ 38.0°C). Maternal and intrapartum characteristics, neonatal outcomes, and inflammatory placental pathology were compared by trend analysis, intergroup difference analysis, and multivariable analysis. RESULTS The degree of intrapartum fever was significantly associated with younger maternal age, nulliparity, longer duration of rupture of membrane, and epidural analgesia (p < 0.001). And the incidence of neonatal proven sepsis and mortality were not significantly different among the groups. The degree of intrapartum fever was associated with the stage of acute chorioamnionitis and funisitis (p < 0.001). Multivariate analysis revealed that the association with epidural analgesia was stronger in borderline fever than overt fever (adjusted odds ratio [95% confidence interval], borderline fever = 18.487 [11.447-29.857]; overt fever = 11.068 [4.874-25.133]) after controlling for maternal age, parity, induction or augmentation, duration of ROM, birth weight, and meconium staining. CONCLUSION Our data support that both epidural analgesia and inflammation of the placenta may contribute to the development of intrapartum fever at term.

Adverse Maternal and Neonatal Outcomes in Women With Elevated Intrapartum Temperature Complicated by Histological Chorioamnionitis at Term: A Propensity-Score Matched Study. Front Pediatr 2021; 9:654596. [PMID: 34368025 PMCID: PMC8344350 DOI: 10.3389/fped.2021.654596] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 03/22/2021] [Indexed: 01/22/2023] Open
Abstract
Background: Elevated intrapartum temperature has been widely proven to be associated with adverse clinical outcomes in both mothers and neonates. Histological chorioamnionitis (HCA), the inflammation of chorion and amniotic membranes, is commonly observed in those with elevated intrapartum temperature. Thus, we aimed to explore whether the combination of HCA would further affect the pregnancy outcomes in those with intrapartum temperature ≥ 37.5°C. Methods: This retrospective cohort study was conducted at the International Peace Maternity and Child Health Hospital (IPMCH), including all full-term women with intrapartum temperature ≥ 37.5°C from Jan 2017 to Jan 2019. Patients were divided in to HCA group or control group according to placental pathology results, and we used 1:1 propensity score matching (PSM) to reduce the effects of potential confounding factors between the two groups. Univariate and multivariable logistic regression were used to identify the association between HCA and different adverse maternal and neonatal outcomes. Results: We formed a propensity-score matched cohort containing 464 women in each group. Higher positive rate of mycoplasma (14.01% vs. 7.33%, p = 0.001) was found in the vaginal secretion culture of women in the HCA group. After adjusting for various baseline clinical characteristics, women with HCA were more likely to end their delivery by cesarean section (AOR = 1.55, 95% CI: 1.05-2.28), and puerperal morbidity (AOR = 2.77, 95% CI: 1.44-5.33) as well as prolonged hospitalization (AOR = 1.56, 95% CI: 1.12-2.17) were more likely to be observed in the HCA group. The existence of HCA might also be associated with neonatal sepsis (AOR = 2.83, 95% CI: 1.14-7.04) and NICU admission (AOR = 1.40, 95% CI: 1.04-1.87) in newborns. In the study on the impact of different stages of HCA, we found that both maternal and neonatal outcomes would not be affected by mild HCA (stage I), while HCA of stage III was associated with increased need for neonatal respiratory support and elevated likelihood of prolonged hospitalization in neonates. Conclusions: Elevated intrapartum temperature complicated by HCA might be related to the elevated occurrence of several adverse maternal and neonatal outcomes, except those with HCA of stage I. Advanced HCA stage correlated with a worse prognosis.

Randomized control trial of intravenous acetaminophen for reduction of intrapartum maternal fever. Am J Obstet Gynecol MFM 2020; 3:100287. [PMID: 33451627 DOI: 10.1016/j.ajogmf.2020.100287] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 11/20/2020] [Accepted: 12/01/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND Intravenous acetaminophen reaches a higher mean peak plasma concentration than oral acetaminophen in a shorter period of time. The favorable pharmacokinetics of intravenous acetaminophen may be beneficial for treating intrapartum maternal fever. OBJECTIVE The primary objective was to compare intravenous and oral acetaminophen in time to defervescence (temperature <38°C). The secondary objective was to compare intravenous and oral acetaminophen in the percentage of participants being afebrile and percent reduction in maternal temperature 30 minutes after administration of first dose. Other outcomes evaluated were histopathological placental findings; neonatal outcomes; oxidative stress; and levels of RANTES, interferon-δ, interleukin 1β, interleukin 2, interleukin 4, interleukin 6, interleukin 8, interleukin 10, interleukin 13, and tumor necrosis factor-α in maternal and neonatal blood. STUDY DESIGN This was a randomized, comparator-controlled, double-dummy, double-blind clinical trial. At the onset of intrapartum fever ≥38°C, patients ≥36 weeks' gestation were either randomized to the control or experimental study arm. Patients in the control arm received 1000 mg of oral acetaminophen capsules and an intravenous placebo resembling intravenous acetaminophen. Patients randomized to the experimental arm received 1000 mg of intravenous acetaminophen and oral placebo capsules resembling acetaminophen. Maternal temperatures and fetal heart rates were recorded at consecutive intervals following administration of the first dose of acetaminophen. Maternal blood, collected at the onset of fever and after delivery, and neonatal cord blood collected at delivery were evaluated for oxidative stress (glutathione levels), levels of RANTES and cytokines (interferon-δ, interleukin 1β, interleukin 2, interleukin 4, interleukin 6, interleukin 8, interleukin 10, interleukin 13, and tumor necrosis factor-α). Placentas were collected for pathologic review. A P value of <.05 was considered statically significant. RESULTS A total of 121 patients (55 in the intravenous and 66 in the oral group) were recruited from December 1, 2016, to February 28, 2018. Patient demographics and intrapartum factors were similar between both arms. The intravenous group showed a mean time of 54.86 minutes (95% confidence interval, 20.57-39.43) to defervescence vs 52.58 minutes (95% confidence interval, 16.58-43.42) in the oral group (P=.71). In addition, intravenous and oral acetaminophen showed similar results in percentage of patients being afebrile and percent reduction in maternal temperature 30 minutes after administration of the first dose. Histopathological findings, neonatal outcomes, oxidative stress markers, and RANTES and cytokine levels were not statistically significant between intravenous and oral acetaminophen groups. CONCLUSION Intravenous acetaminophen did not demonstrate a higher efficacy than oral acetaminophen in treating intrapartum maternal fever. Select patients may benefit from intravenous acetaminophen for treatment of intrapartum fever, including those who cannot tolerate oral medication.

[PMID: 33007269 PMCID: PMC8315154 DOI: 10.1016/j.ajog.2020.09.044] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 09/08/2020] [Accepted: 09/24/2020] [Indexed: 02/09/2023]
Abstract
This review aimed to examine the existing evidence about interventions proposed for the treatment of clinical chorioamnionitis, with the goal of developing an evidence-based contemporary approach for the management of this condition. Most trials that assessed the use of antibiotics in clinical chorioamnionitis included patients with a gestational age of ≥34 weeks and in labor. The first-line antimicrobial regimen for the treatment of clinical chorioamnionitis is ampicillin combined with gentamicin, which should be initiated during the intrapartum period. In the event of a cesarean delivery, patients should receive clindamycin at the time of umbilical cord clamping. The administration of additional antibiotic therapy does not appear to be necessary after vaginal or cesarean delivery. However, if postdelivery antibiotics are prescribed, there is support for the administration of an additional dose. Patients can receive antipyretic agents, mainly acetaminophen, even though there is no clear evidence of their benefits. Current evidence suggests that the administration of antenatal corticosteroids for fetal lung maturation and of magnesium sulfate for fetal neuroprotection to patients with clinical chorioamnionitis between 24 0/7 and 33 6/7 weeks of gestation, and possibly between 23 0/7 and 23 6/7 weeks of gestation, has an overall beneficial effect on the infant. However, delivery should not be delayed to complete the full course of corticosteroids and magnesium sulfate. Once the diagnosis of clinical chorioamnionitis has been established, delivery should be considered, regardless of the gestational age. Vaginal delivery is the safer option and cesarean delivery should be reserved for standard obstetrical indications. The time interval between the diagnosis of clinical chorioamnionitis and delivery is not related to most adverse maternal and neonatal outcomes. Patients may require a higher dose of oxytocin to achieve adequate uterine activity or greater uterine activity to effect a given change in cervical dilation. The benefit of using continuous electronic fetal heart rate monitoring in these patients is unclear. We identified the following promising interventions for the management of clinical chorioamnionitis: (1) an antibiotic regimen including ceftriaxone, clarithromycin, and metronidazole that provides coverage against the most commonly identified microorganisms in patients with clinical chorioamnionitis; (2) vaginal cleansing with antiseptic solutions before cesarean delivery with the aim of decreasing the risk of endometritis and, possibly, postoperative wound infection; and (3) antenatal administration of N-acetylcysteine, an antioxidant and antiinflammatory agent, to reduce neonatal morbidity and mortality. Well-powered randomized controlled trials are needed to assess these interventions in patients with clinical chorioamnionitis.

Epidural analgesia, intrapartum hyperthermia, and neonatal brain injury: a systematic review and meta-analysis. Br J Anaesth 2020; 126:500-515. [PMID: 33218673 DOI: 10.1016/j.bja.2020.09.046] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 09/21/2020] [Accepted: 09/23/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Epidural analgesia is associated with intrapartum hyperthermia, and chorioamnionitis is associated with neonatal brain injury. However, it is not known if epidural hyperthermia is associated with neonatal brain injury. This systematic review and meta-analysis investigated three questions: (1) does epidural analgesia cause intrapartum hyperthermia, (2) is intrapartum hyperthermia associated with neonatal brain injury, and (3) is epidural-induced hyperthermia associated with neonatal brain injury? METHODS PubMed, ISI Web of Knowledge, The Cochrane Library, and Embase were searched from inception to January 2020 using Medical Subject Headings (MeSH) terms relating to epidural analgesia, hyperthermia, labour, and neonatal brain injury. Studies were reviewed independently for inclusion and quality by two authors (Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach). Two meta-analyses were performed using the Mantel-Haenszel fixed effect method to generate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Forty-one studies were included for Question 1 (646 296 participants), 36 for Question 2 (11 866 021 participants), and two studies for Question 3 (297 113 participants). When the mode of analgesia was randomised, epidural analgesia was associated with intrapartum hyperthermia (OR: 4.21; 95% CI: 3.48-5.09). There was an association between intrapartum hyperthermia and neonatal brain injury (OR: 2.79; 95% CI: 2.54-2.3.06). It was not possible to quantify the association between epidural-induced hyperthermia and neonatal brain injury. CONCLUSIONS Epidural analgesia is a cause of intrapartum hyperthermia, and intrapartum hyperthermia of any cause is associated with neonatal brain injury. Further work is required to establish if epidural-induced hyperthermia is a cause of neonatal brain injury.

Abstract
INTRODUCTION AND HYPOTHESIS With the increasingly extensive application of epidural analgesia, its effect on pelvic floor function outcomes has received growing attention. The aim of the study is to determine the possible effect of epidural analgesia on pelvic floor muscle (PFM) endurance and strength and the prevalence of urinary incontinence (UI) and stress urinary incontinence (SUI) at 6 weeks postpartum. METHODS This is a retrospective cohort study of 333 primiparous women after vaginal delivery. At 6 weeks postpartum, a vaginal balloon connected to a high-precision pressure transducer was used to measure PFM strength and endurance. SUI/UI was determined using the verified Chinese International Classification of Urinary Incontinence Short Form (ICIQ-UI-SF) questionnaire. Statistical analysis was performed using binary logistic regression and multiple linear regression analysis. RESULTS Women in the epidural analgesia group experienced longer first and second stages of labor (p < 0.05). There were no statistically significant differences in the rates of perineal lacerations, forceps assistance or episiotomy between women with or without epidural analgesia (p > 0.05). No statistically significant differences were found in PFM endurance (B: 0.933, 95% CI confidence interval: -1.413 to 3.278, p: 0.435) or PFM strength (B: 0.044, 95% CI: -3.204 to 3.291, p:0.979) between these two groups. In addition, the prevalence of UI (30.77% vs. 26.87%) and SUI (21.54% vs. 16.42%) in women with or without epidural analgesia was not statistically significant (p > 0.05). CONCLUSIONS PFM function and UI prevalence at 6 weeks postpartum are not significantly affected by epidural analgesia.

Abstract
There is a lack of consensus in the international scientific community with respect to the most suitable hydration strategies when attending nulliparous women during low-risk births. This paper describes the protocol for a randomized controlled trial to compare two hydration strategies and their influence on maternal and neonatal morbidity. The study population consists of nulliparous women admitted to the obstetrics department of a University Hospital. The women are being randomized into two groups: the "optimal hydration" group, which will be guaranteed 300 ml/hr liquids (crystalloids and bottled mineral water) with a minimum diuresis of 35 ml/hr; and the "variability in hydration" group, which will receive intravenous (alternating normal saline, Ringer's lactate solution, glucose, or Voluven®) and clear (bottled mineral water or isotonic drinks [Aquarius®]) liquids, without any established perfusion rate, and without established minimum diuresis. Outcomes for mothers include duration of labor, cesarean section, fever, and dehydration. Outcomes for newborns are respiratory distress, hypoglycemia, hyponatremia, jaundice, weight loss over 48 hr, and breastfeeding difficulties. Analysis will be per-protocol. Administering optimal hydration may improve health and safety for mothers and their newborn and reduce maternal and neonatal morbidity. The study is registered at www.clinicaltrials.gov. The project received funding by the Ministry of Health of Spain and is approved by the Research Ethics Committee.

Abstract
PURPOSE To analyze the clinical outcomes following the implementation of a new standard labor procedure. METHODS This was a retrospective analysis that included a study group consisting of patients managed based on a new standard labor protocol and a control group comprising patients managed under an old standard labor protocol. The following maternal and perinatal outcomes were compared in the two groups: the indications for a cesarean section and the incidence of cesarean section, postpartum hemorrhage, fetal distress, neonatal asphyxia and pediatric intervention. We also compared the average number of days spent in the hospital, the incidence of medical disputes and hospitalization expenses. RESULTS The cesarean section rates for the study and control groups were 19.29% (401/2079) and 33.53% (753/2246), respectively (P < 0.05). The main indications for a cesarean section in the study group were arrest of the active phase of labor, fetal distress and intrapartum fever; the percentages of each indication were significantly different from those of the control group (P < 0.001). The rates of postpartum hemorrhage in the study group and control group were 7.74% (130/1678) and 8.1% (121/1493), respectively (P = 0.710). The incidence rates of severe perineal lacerations were 0.48% (8/1678) for the study group and 0.2% (3/1493) for the control group (P = 0.187). The rates of forceps use were 4.29% (72/1678) in the study group and 2.41% (36/1493) in the control group (P = 0.004). The incidence rate of fetal distress in the study group was 6.24% (169/2709) and 4.67% (105/2246) (P = 0.006) in the control group. No significant difference was observed in the incidence of neonatal asphyxia and pediatric interventions between the two groups (0.74% (20/2709) vs. 8.12% (220/2709) and 17 (0.76%) vs. 161 (7.17%), respectively). The average length of hospital stay was 4.74 ± 1.15 and 2.13 ± 1.23 days (P < 0.01). The incidence of medical disputes was significantly different between the two groups: 1.44% (30/2079) in the study group and 0.53% (12/2246) in the control group (P < 0.01). The hospitalization expenses were 5401.29 ± 296.33 yuan in the study group and 5253.53 ± 3655.79 yuan in the control group (P = 0.06). CONCLUSIONS The implementation of the new labor protocol reduced the cesarean section rate without negatively impacting maternal and neonatal outcomes. In practice, bed turnover and the hospital utilization rate should be better controlled, patient-doctor communication should be strengthened and the quality of obstetrical service should be improved.
