RESUMO

OBJECTIVE: To examine whether the duration of time from initiation of general endotracheal anesthesia (GETA) to delivery for cesarean deliveries (CDs) performed is related to perinatal outcomes. STUDY DESIGN: This is a retrospective study of patients with singleton nonanomalous gestations undergoing CD ≥37 weeks of gestation under GETA with reassuring fetal status at a single tertiary care center from 2000 to 2016. Duration from GETA initiation until delivery was calculated as the time interval from GETA induction to delivery (I-D), categorized into tertiles. Outcomes for those in the tertile with the shortest I-D were compared with those in the other two tertiles. The primary perinatal outcome was a composite of complications (continuous positive airway pressure or high-flow nasal cannula for ≥2 consecutive hours, inspired oxygen ≥30% for ≥4 consecutive hours, mechanical ventilation, stillbirth, or neonatal death ≤72 hours after birth). Secondary outcomes were 5-minute Apgar score <7 and a composite of maternal morbidity (bladder injury, bowel injury, and extension of hysterotomy). Bivariable and multivariable analyses were used to compare outcomes. RESULTS: Two hundred eighteen maternal-perinatal dyads were analyzed. They were dichotomized based on I-D ≤4 minutes (those in the tertile with the shortest duration) or >4 minutes. Women with I-D >4 minutes were more likely to have prior abdominal surgery and less likely to have labored prior to CD. I-D >4 minutes was associated with significantly increased frequency of the primary perinatal outcome. This persisted after multivariable adjustment. In bivariable analysis, 5-minute Apgar <7 was more common in the group with I-D >4 minutes, but this did not persist in multivariable analysis. Frequency of maternal morbidity did not differ. CONCLUSION: When CD is performed at term using GETA without evidence of nonreassuring fetal status prior to delivery, I-D interval >4 minutes is associated with increased frequency of perinatal complications. KEY POINTS: · Cesarean delivery under general anesthesia is associated with increased perinatal complications.. · Perinatal complications are increased with increasing duration of exposure to general anesthetics.. · Maternal complications were not increased with shorter duration of exposure to general anesthesia..

RESUMO

OBJECTIVE: To evaluate complications associated with early postpartum therapeutic anticoagulation. METHODS: A multicenter retrospective cohort study was done to evaluate the association between therapeutic anticoagulation postpartum and major complications (hemorrhagic and wound complications). Secondary outcomes included minor complications, risk factors associated with total complications (including the time to therapeutic anticoagulation resumption after delivery) and recurrent thrombotic events within 6 weeks postpartum. RESULTS: From 2003 to 2015, 232 consecutive women were treated with therapeutic anticoagulation within 96 hours postpartum; among those treated, 91 received unfractionated heparin, 138 received low-molecular-weight heparin, and three received other anticoagulants. The primary outcome, a composite of major hemorrhagic complications (requiring transfusion, hospitalization, volume resuscitation, transfer to intensive care unit, or surgery) and major wound complications, occurred in 7 of 83 (8.4%) for cesarean deliveries and 9 of 149 (6.0%) for vaginal deliveries (P=.490). Total complications (including major and minor hemorrhagic and wound complications) occurred in 13 of 83 (15.7%) for cesarean deliveries compared with 9 of 149 (6.0%) for vaginal deliveries (P=.016). When comparing cases associated with and without complications, the median delay before resuming anticoagulation was significantly shorter for both cesarean (12 vs 33 hours, P=.033) and vaginal deliveries (6 vs 19 hours, P=.006). For vaginal deliveries, 8 of 51 (15.7%) women had complications when anticoagulation was started before 9.25 hours postpartum, compared with 1 of 98 (1.0%) when started after 9.25 hours. For cesarean deliveries, 7 of 21 (33.3%) of women experienced complications compared with 6 of 62 (9.7%) if anticoagulation was started before or after 15.1 hours, respectively. Two (0.9%) episodes of venous thromboembolism occurred within 6 weeks postpartum. CONCLUSION: Among postpartum women who received early therapeutic anticoagulation, major complications occurred in 8.4% for cesarean deliveries and 6.0% for vaginal deliveries. Complications were associated with earlier resumption of therapeutic anticoagulation, particularly before 9.25 hours for vaginal deliveries and before 15.1 hours for cesarean deliveries.

RESUMO

Neuromyelitis optica spectrum disorders (NMOSD) are a type of neurological autoimmune disease characterized by attacks of CNS inflammation that are often severe and predominantly affect the spinal cord and optic nerve. The majority of individuals with NMOSD are women, many of whom are of childbearing age. Although NMOSD are rare, several small retrospective studies and case reports have indicated that pregnancy can worsen disease activity and might contribute to disease onset. NMOSD disease activity seems to negatively affect pregnancy outcomes. Moreover, some of the current NMOSD treatments are known to pose risks to the developing fetus and only limited safety data are available for others. Here, we review published studies regarding the relationship between pregnancy outcomes and NMOSD disease activity. We also assess the risks associated with using disease-modifying therapies for NMOSD during the course of pregnancy and breastfeeding. On the basis of the available evidence, we offer recommendations regarding the use of these therapies in the course of pregnancy planning in individuals with NMOSD.

RESUMO

Objective: To investigate the curative effect of remifentanil on analgesia in newborns.Patients and methods: One hundred and twenty full-term puerperae from January 2013 to December 2013 were selected and randomly divided into three groups: remifentanil patient-controlled intravenous labor analgesia group (Group A, n = 40), patient-controlled epidural analgesia (PCEA) group (Group B, n = 40), and spontaneous labor group (Group C, n = 40). General conditions, visual analogue scale (VAS) score, labor stage, bleeding, delivery mode, neonatal asphyxia rate, oxyhemoglobin saturation in puerpera, and umbilical arterial blood gas analysis indexes of the fetus were measured. In addition, complications and adverse reactions were recorded.Results: VAS scores in Group A and B were significantly lower than that in Group C at each time point after analgesic intervention (p < .05), without differences at 30 min and 1 h after analgesia between Group A and B (p > .05). However, VAS scores in Group A were significantly higher than those in Group B at the full opening of the uterine orifice and fetal delivery (p < .05). The active phases in the first stage of labor in Group A and B were significantly shorter than that in Group C (p <.05). There were no significant differences in general conditions, VAS score before analgesia, the second and third stages of labor, delivery mode, bleeding, neonatal asphyxia rate, oxyhemoglobin saturation, pH value, partial pressure of oxygen (PO2), and partial pressure of carbon dioxide (PCO2) among three groups (p > .05).Conclusions: Remifentanil intravenous labor analgesia is not superior to PCEA, but does not increase adverse effects, suggesting it might be a supplementary method of PCEA.

RESUMO

AIM: This study aimed to investigate the rate of labor-onset hypertension (LOH) under neuraxial labor analgesia and the effect of neuraxial labor analgesia on LOH. METHODS: A retrospective study was conducted in a tertiary university hospital from 2015 to 2016. Patients who were admitted to the hospital for vaginal delivery under combined spinal and epidural anesthesia were selected. LOH was defined as the elevation of systolic blood pressure (BP) to ≥140 mmHg or diastolic BP to ≥90 mmHg for the first time after the onset of labor. Cases of LOH that persisted after neuraxial labor analgesia (prolonged LOH) were further analyzed to determine the hypertension severity and therapeutic intervention rate. RESULTS: Among 775 patients, 213 (28.4%) developed LOH. Prolonged LOH was observed in 30 patients (3.9%). LOH severity and the likelihood of prolonged LOH were positively correlated. Therapeutic intervention was administered only to the patients with prolonged LOH, that is, to 100% of those with emergent hypertension, to 21.1% of those with severe hypertension during labor, and to 36.8% of those with severe hypertension, to 55.6% of those with mild hypertension in the post-partum period. CONCLUSION: The rate of LOH was reduced significantly after neuraxial labor analgesia. Patients with prolonged LOH should be carefully followed up during labor and in the post-partum period because such patients often require antihypertensive therapy.

RESUMO

BACKGROUND: The trial of labor after cesarean section (TOLAC) is a relatively new technique in mainland of China, and epidural analgesia is one of the risk factors for uterine rupture. This study aimed to evaluate the effect of epidural analgesia on primary labor outcome [success rate of vaginal birth after cesarean (VBAC)], parturient complications and neonatal outcomes after TOLAC in Chinese multiparas based on a strictly uniform TOLAC indication, management and epidural protocol. METHODS: A total of 423 multiparas undergoing TOLAC were enrolled in this study from January 2017 to February 2018. Multiparas were divided into two groups according to whether they received epidural analgesia (study group, N = 263) or not (control group, N = 160) during labor. Maternal delivery outcomes and neonatal characteristics were recorded and evaluated using univariate analysis, multivariable logistic regression and propensity score matching (PSM). RESULTS: The success rate of VBAC was remarkably higher (85.55% vs. 69.38%, p < 0.01) in study group. Epidural analgesia significantly shortened initiating lactation period and declined Visual Analogue Score (VAS). It also showed more superiority in neonatal umbilical arterial blood pH value. After matching by PSM, multivariable logistic regression revealed that the correction of confounding factors including epidural analgesia, cervical Bishop score at admission and spontaneous onset of labor were still shown as promotion probability in study group (OR = 4.480, 1.360, and 10.188, respectively; 95%CI = 2.025-10.660, 1.113-1.673, and 2.875-48.418, respectively; p < 0.001, p = 0.003, and p < 0.001, respectively). CONCLUSIONS: Epidural analgesia could reduce labor pain, and no increased risk of postpartum bleeding or uterine rupture, as well as adverse effects in newborns were observed. The labor duration of multiparas was increased, but within acceptable range. In summary, epidural analgesia may be safe for both mother and neonate in the three studied hospitals.

RESUMO

The primary aim of this study was to analyze the impact of schizophrenic disorders on pregnancy outcomes. The secondary aim was to briefly analyze the potential role of antipsychotic treatment on influencing pregnancy outcomes in expectant mothers with schizophrenia. We searched the MEDLINE, PsycINFO, and Science.gov databases for articles published in English from January 1980 to January 2019. We used the following search terms: 'schizophrenia', 'motherhood', 'pregnancy/foetal/neonatal outcomes', and 'birth defects'. The reference lists of retrieved articles were also consulted to find additional pertinent studies missed in the electronic search and/or those published before 1980. Data were extracted from articles that provided primary data on the impact of maternal schizophrenia spectrum disorders on obstetrical and perinatal outcomes. After excluding duplicates, 35 articles were identified. Systematic reviews were searched on the same databases to briefly assess the effects of antipsychotics on pregnancy outcomes. The reviewed studies showed several limitations. They were published during a time range from the early 1970s to 2019. During this period, there were significant changes in the diagnostic criteria for schizophrenia. Moreover, such studies showed no homogeneity in the investigation of potential confounders. Most importantly, no research has differentiated the effects of maternal illness on pregnancy, fetal, and neonatal outcomes from those associated with antipsychotic treatments. Thus, it is not surprising that such studies show conflicting results. Despite such limitations, in managing pregnant women with schizophrenia clinicians should consider an integrated approach that includes: antipsychotic treatment, psychological treatment, optimal dietary approaches for prevention of excessive weight gain and gestational diabetes, meticulous gynecologic and obstetric surveillance, and social and occupational support.

RESUMO

OBJECTIVE: In Africa, 80% of women ingest traditional medicine (TM) during pregnancy. Although widely used in Cameroon, no study in has either demonstrated its safety or effectiveness. Hence, we sought to determine the effects of TM ingestions during the peri-partum period on maternal and foetal outcomes. A cohort study was conducted from January to April 2016 in two referral maternity departments of Cameroon. We consecutively enrolled all consenting parturients with gestational age above 28 weeks. We divided them into two groups; exposed and unexposed. The exposure studied was ingestion of TM within 72 h prior to delivery. Variables studied were socio-demographic characteristics, type and frequency of TM ingested and details of labour. RESULTS: We enrolled a total of 603 parturients of whom 147 in the exposed group and 456 in the non-exposed group. The most frequently used TM were honey and Triumfetta pentandra A. Ingestion of TM in the peri-paritum period was associated with intra-partum vaginal bleeding, dystocic labour, tachysystole and uterine atony. No adverse neonatal outcome was observed. Overall, these findings could help guide the direction of future research into the safety and potential benefits of peri-partum TM use, as well as serving as a preliminary reference for counselling.

RESUMO

AIM: To evaluate the safety, effect on breastfeeding and efficacy of a combination of pethidine and levallorphan (Pethilorfan) for pain relief during labor. METHODS: We compared maternal or neonatal morbidities, suckling difficulties in newborns and breastfeeding rates between 177 women who received 50-200 mg (as pethidine) of Pethilorfan during labor (Pethilorfan group) and 354 women who delivered their infants without analgesic drugs immediately before or after each woman in the Pethilorfan group (control group) from January 1, 2005 to December 31, 2016. We performed univariate and multivariate analyses for comparison between the two groups. We also evaluated the efficacy of Pethilorfan retrospectively. RESULTS: The Pethilorfan group included more women with prolonged and/or operative deliveries than the control group. Nevertheless, no significant differences were seen between the two groups in the rates of Apgar scores less than 7 at 1 or 5 min, composite neonatal morbidities, hyperbilirubinemia or respiratory disturbances. The incidence of suckling difficulties lasting over 24 h and the breastfeeding rates at discharge or after 1 month were also similar. Maternal adverse effects of Pethilorfan were generally mild and transient. The efficacy ratio of Pethilorfan was 83.6%, although its analgesic effect was usually incomplete. CONCLUSION: Pethilorfan can be used safely for labor pain relief without increasing maternal or neonatal morbidities, or impeding breastfeeding, if it is administered at a prudent dosage. Parenteral opioids including Pethilorfan should remain as an option for treating women in labor pain, particularly when epidural analgesia is not readily available or contraindicated.

RESUMO

BACKGROUND: Epidural-related maternal fever (ERMF) has been reported in ∼26% of labouring women. The underlying mechanisms remain unclear. We hypothesised that ERMF is promoted by bupivacaine disrupting cytokine production/release from mononuclear leucocytes [mononuclear fraction (MNF)]. We examined whether bupivacaine (i) reduces caspase-1 activity and release of the anti-pyrogenic cytokine interleukin (IL)-1 receptor antagonist (IL-1ra), and (ii) is pro-inflammatory through mitochondrial injury/IL-1ß. METHODS: In labouring women, blood samples were obtained before/after epidural analgesia was implemented. Maternal temperature was recorded hourly for the first 4 h of epidural analgesia. Time-matched samples/temperatures were obtained from labouring women without epidural analgesia, pregnant non-labouring, and non-pregnant women. The primary clinical outcome was change in maternal temperature over 4 h after the onset of siting epidural catheter/enrolment. The secondary clinical outcome was development of ERMF (temperature ≥ 38°C). The effect of bupivacaine/saline on apoptosis, caspase-1 activity, intracellular IL-1ra, and plasma IL-1ra/IL-1ß ratio was quantified in MNF from labouring women or THP-1 monocytes (using flow cytometry, respirometry, or enzyme-linked immunosorbent assay). RESULTS: Maternal temperature increased by 0.06°C h-1 [95% confidence interval (CI): 0.03-0.09; P=0.003; n=38] after labour epidural placement. ERMF only occurred in women receiving epidural analgesia (five of 38; 13.2%). Bupivacaine did not alter MNF or THP-1 apoptosis compared with saline control, but reduced caspase-1 activity by 11% (95% CI: 5-17; n=10) in MNF from women in established labour. Bupivacaine increased intracellular MNF IL-1ra by 25% (95% CI: 10-41; P<0.001; n=10) compared with saline-control. Epidural analgesia reduced plasma IL-1ra/IL-1ß ratio (mean reduction: 14; 95% CI: 7-30; n=30) compared with women without epidural analgesia. CONCLUSIONS: Impaired release of anti-pyrogenic IL-1ra might explain ERMF mechanistically. Immunomodulation by bupivacaine during labour could promote ERMF.

RESUMO

Afortunadamente, las arritmias malignas en un embarazo de curso normal son raras y la mayoría de las quejas por palpitaciones se deben a arritmias benignas. Dentro de ellas las taquicardias supraventriculares paroxísticas (TSP) se describen en la literatura con relativa frecuencia y pueden ocurrir sólo, o incluso exacerbarse, durante el embarazo, debido a un efecto pro-arritmogénico de la gestación. Así en pacientes gestantes la carga hemodinámica y los cambios del tono autonómico facilitan la aparición de arritmias, más frecuentemente en mujeres con limitada reserva cardíaca y pueden llegar a comprometer la supervivencia del feto y de la madre debido a las consecuencias hemodinámicas o los efectos adversos de los tratamientos farmacológicos y no farmacológicos. Presentamos el caso de una gestante a término que durante el trabajo de parto, posterior a la administración de analgesia epidural con ropivacaína y fentanilo, sufre un cuadro de hipotensión materna y bradicardia materna/fetal mantenida que requiere ser medicada con efedrina y atropina intravenosa. Inmediatamente presenta palpitaciones y dolor torácico sostenido, diagnosticándosele TSP que cede con la administración de adenosina intravenosa, no repitiendo nuevos episodios durante el trabajo de parto ni puerperio. En nuestro caso la arritmia ocurrió como efecto adverso de la efedrina y administradas para recuperar el cuadro de hipotensión causada por la analgesia epidural.

RESUMO

BACKGROUND: Prior studies have shown that using uterotonics to augment or induce labor before arrival at comprehensive Emergency Obstetric and Neonatal Care (CEmONC) settings (henceforth, "outside uterotonics") may contribute to perinatal mortality in low- and middle-income countries. We estimate its effect on perinatal mortality in rural Bangladesh. METHODS: Using hospital records (23986 singleton term births, Jan 1, 2009-Dec 31, 2015) from rural Bangladesh, we use a logistic regression model to estimate the increased risk of perinatal death from uterotonics administered outside a CEmONC facility. RESULTS: Among term births (≥37 weeks gestation), the risk of perinatal death adjusted for key confounders is significantly increased among women reporting uterotonic use outside of CEmONC (OR = 3 · 0, 95 % CI = 2 · 4,3 · 7). This increased risk is particularly high for fresh stillbirths (OR = 4 · 0, 95 % CI = 3 · 0,5 · 3) and intrapartum-related causes of early neonatal deaths (birth asphyxia) (OR = 3 · 1, 95 % CI = 2 · 2,4 · 5). CONCLUSIONS: In this sample, outside uterotonic use was associated with substantially increased risk of fresh stillbirths, deaths due to birth asphyxia, and all perinatal deaths. In settings of high uterotonic use outside of controlled settings, substantial improvement in both stillbirth and early neonatal mortality may be made by reducing such use.

RESUMO

Intrapartum fever is associated with excessive maternal interventions as well as higher neonatal morbidity. Epidural-related maternal fever (ERMF) contributes to the development of intrapartum fever. The mechanism(s) for ERMF has remained elusive. Here, we consider how inflammatory mechanisms may be modulated by local anesthetic agents and their relevance to ERMF. We also critically reappraise the clinical data with regard to emerging concepts that explain how anesthetic drug-induced metabolic dysfunction, with or without activation of the inflammasome, might trigger the release of nonpathogenic, inflammatory molecules (danger-associated molecular patterns) likely to underlie ERMF.

RESUMO

Prolonged paralysis due to a quantitative or qualitative deficiency of pseudocholinesterase activity is an uncommon but known side effect of succinylcholine. We describe a patient who experienced prolonged paralysis following administration of succinylcholine for general anesthesia and endotracheal intubation for an emergent cesarean section despite laboratory evidence of normal enzyme function. The patient required mechanical ventilation in the intensive care unit for several hours following surgery. The patient was extubated following return of full muscle strength and had a good outcome. The enzyme responsible for the metabolism of succinylcholine, pseudocholinesterase, was determined to be low in quantity in this patient but was functionally normal. This low level, by itself, was unlikely to be solely responsible for the prolonged paralysis. The patient likely had an abnormal pseudocholinesterase enzyme variant that is undetectable by standard laboratory tests.

RESUMO

IMPORTANCE: Glyburide is thought to be safe for use during pregnancy for treatment of gestational diabetes mellitus (GDM). However, there are limited data on the effectiveness of glyburide when compared with insulin as used in a real-world setting. OBJECTIVE: To estimate the risk of adverse maternal and neonatal outcomes in women with GDM treated with glyburide compared with insulin. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of a population-based cohort from a nationwide US employer-based insurance claims database from January 1, 2000, to December 31, 2011. We identified women with GDM and their newborns. We excluded those with type 1 or 2 diabetes and those younger than 15 years or older than 45 years. EXPOSURES: Treatment with glyburide or insulin during pregnancy within 150 days before delivery. MAIN OUTCOMES AND MEASURES: We used binomial regression to estimate risk ratios (RRs) and risk differences with 95% confidence intervals for the association of glyburide with diagnosis codes for obstetric trauma, cesarean delivery, birth injury, preterm birth, hypoglycemia, respiratory distress, jaundice, large for gestational age, and hospitalization in the neonatal intensive care unit. Inverse probability of treatment weights were used to adjust for maternal characteristics that differed between the treatment groups. RESULTS: Among 110,879 women with GDM, 9173 women (8.3%) were treated with glyburide (n = 4982) or insulin (n = 4191). After adjusting for differences at baseline, newborns of women treated with glyburide were at increased risk for neonatal intensive care unit admission (RR = 1.41; 95% CI, 1.23-1.62), respiratory distress (RR = 1.63; 95% CI, 1.23-2.15), hypoglycemia (RR = 1.40; 95% CI, 1.00-1.95), birth injury (RR = 1.35; 95% CI, 1.00-1.82), and large for gestational age (RR = 1.43; 95% CI, 1.16-1.76) compared with those treated with insulin; they were not at increased risk for obstetric trauma (RR = 0.92; 95% CI, 0.71-1.20), preterm birth (RR = 1.06; 95% CI, 0.93-1.21), or jaundice (RR = 0.96; 95% CI, 0.48-1.91). The risk of cesarean delivery was 3% lower in the glyburide group (adjusted RR = 0.97; 95% CI, 0.93-1.00). The risk difference associated with glyburide was 2.97% (95% CI, 1.82-4.12) for neonatal intensive care unit admission, 1.41% (95% CI, 0.61-2.20) for large for gestational age, and 1.11% (95% CI, 0.50-1.72) for respiratory distress. CONCLUSIONS AND RELEVANCE: Newborns from privately insured mothers treated with glyburide were more likely to experience adverse outcomes than those from mothers treated with insulin. Given the widespread use of glyburide, further investigation of these differences in pregnancy outcomes is a public health priority.

RESUMO

Some non-steroidal anti-inflammatory drugs increase the risk of retained fetal membranes. This is the first study to investigate the effects of meloxicam on the risk of retained fetal membranes. Administration of meloxicam to dairy cattle immediately following calving revealed no differences in the incidence of retained fetal membranes between meloxicam-treated and untreated animals. There was no difference between the 2 groups in the incidence of periparturient diseases following calving. Meloxicam can be used on the day of calving in lactating cows without increasing the risk of retained fetal membranes.


L'évaluation des effets d'une injection de méloxicam immédiatement après le vêlage chez la vache laitière sur le risque de rétention des membranes foetales. Certains médicaments inflammatoires non-stéroïdiens augmentent le risque de rétention de membranes fœtales. Cette étude est la première à examiner les effets du méloxicam quant au risque de rétention de membranes fœtales. Aucune différence n'a été notée dans le cas de rétention de membranes fœtales lors du vêlage chez la vache laitière entre les vaches qui ont reçu une injection de méloxicam immédiatement après le vêlage et celles qui n'ont rien reçu. De plus, il n'y avait aucune différence d'incidence de maladies périnatales observées suite au vêlage entre les deux groupes. On peut donc administrer du méloxicam aux vaches laitières le jour du vêlage sans augmenter le risque de rétention de membranes fœtales.(Traduit par les auteurs).

RESUMO

Anaphylactic-like reaction or anaphylactoid reaction resembles generalized anaphylaxis but is not caused by immunoglobulin E-mediated allergic reaction. This reaction is caused by a non-immunologic mechanism even after first exposure to antigen. Prostaglandin E2 (dinoprostone) gel is commonly used for pre-induction cervical ripening. We report a case of anaphylactiod reaction after insertion of prostaglandin E2 gel for induction of labor. Hyperstimulation with dinoprostone gel is reported in the literature. An isolated report of three cases of anaphylactiod reaction after intracervical dinoprostone gel was found during a literature search. We are reporting this case for its rarity. As a potentially life-threatening condition, every obstetrician should be aware of this rare complication of dinoprostone gel.
