Objective: To investigate the perinatal maternal and fetal adverse outcomes of cesarean section in the different duration of the second stage of labor. Methods: A retrospective cohort study was conducted on the clinical data of 154 pregnant women with singleton head pregnancy who underwent cesarean section at different times of the second stage of labor due to maternal and fetal factors in the First Affiliated Hospital of Nanjing Medical University from January 1, 2019 to December 31, 2021. According to the duration of the second stage of labor, they were divided into <2 h group (54 cases), 2-<3 h group (61 cases), and ≥3 h group (39 cases). The general data of pregnant women and neonates, preoperative maternal and neonatal conditions related to labor stages, surgical indications, surgical procedures, and perioperative maternal and neonatal adverse outcomes were compared among the three groups. Results: (1) General Information: there were no significant differences in maternal age, gravidity and parity, proportion of primipara, gestational age at delivery, body mass index before delivery, pregnancy complications, labor analgesia rate and the duration of the first stage of labor among the three groups (all P>0.05). The differences of the gender composition, birth weight and incidence of macrosomia of the three groups were also not statistically significant (all P>0.05). (2) Maternal and fetal status and surgical indications: the incidence of intrapartum fever and type Ⅱ and Ⅲ fetal heart rate monitoring in the <2 h group were higher than those in the 2-<3 h group and the ≥3 h group, and the preoperative fetal head position in the ≥3 h group was lower than that in the 2-<3 h group, with statistically significant differences (all P<0.05). The proportion of cesarean section due to "fetal distress" was 40.7% (22/54) in the <2 h group, which was higher than that in the 2-<3 h group (4.9%, 3/61) and the ≥3 h group (2.6%, 1/39). The proportions of surgical indication of "relative cephalo-pelvic disproportion" were 98.4% (60/61) and 94.9% (37/39) in the 2-<3 h group and ≥3 h group, respectively, and the surgical indication of "fetal head descent arrest" were 41.0% (25/61) and 59.0% (23/39), respectively. Compared with <2 h group [63.0% (34/54), 13.0% (7/54)], the differences were statistically significant (all P<0.05). There were no significant difference in surgical indications between 2-<3 h group and ≥3 h group (all P>0.05). (3) Intraoperative conditions and perioperative complications of cesarean section: the puerperal morbidity rate of <2 h group was 37.0% (20/54), which was higher than those of 2-<3 h group (18.0%, 11/61) and ≥3 h group (7.7%, 3/39), the difference was statistically significant (P<0.05). There were no significant differences in operation time, intraoperative blood loss, incidence of fetal head inlay, uterine incision tear, modified B-Lynch suture for uterine atony, postpartum hemorrhage, perioperative blood transfusion, preoperative hemoglobin (Hb) level, perioperative Hb change, and postoperative hospital stay among the three groups (all P>0.05). (4) Adverse neonatal outcomes: non-hemolytic neonatal hyperbilirubinemia in ≥3 h group was 35.9% (14/39), which was significantly higher than that in <2 h group (13.0%, 7/54; P<0.05). Among the neonates admitted to neonatal intensive care unit (NICU) within 1 week after birth, the proportion of neonates admitted to NICU due to neonatal hyperbilirubinemia in ≥3 h group (15/19) was significantly higher than that in <2 h group (9/17) and 2-<3 h group (10/19), and the differences were statistically significant (all P<0.05). However, there was no significant difference between the <2 h group and the 2-<3 h group (P>0.05). There was no perinatal death in the three groups. Conclusions: The rate of puerperal morbidity is higher in patients who were transferred to cesarean section within 2 hours of the second stage of labor. In the early stage of the second stage of labor, the monitoring of fetal heart rate and amniotic fluid characteristics should be strengthened, especially the presence or absence of prenatal fever. In good maternal and neonatal conditions, conversion to cesarean section after 2 hours of the second stage of labor does not significantly increase the incidence of serious adverse maternal and neonatal outcomes. For the second stage of labor more than 3 hours before cesarean section, it is necessary to strengthen the monitoring of neonatal bilirubin.

BACKGROUND: We aimed to investigate whether various immune-related plasma proteins, alone or in combination with conventional clinical risk factors, can predict spontaneous preterm delivery (SPTD) and intra-amniotic infection in women with premature cervical dilation or a short cervix (≤ 25 mm).METHODS: This retrospective study included 80 asymptomatic women with premature cervical dilation (n = 50) or a short cervix (n = 30), who underwent amniocentesis at 17–29 weeks. Amniotic fluid (AF) was cultured, and maternal plasma was assayed for interleukin (IL)-6, matrix metalloproteinase (MMP)-9, tissue inhibitor of metalloproteinases (TIMP)-1, and complements C3a and C5a, using enzyme-linked immunosorbent assay (ELISA) kits. The primary outcome measures were SPTD at < 32 weeks and positive AF cultures.RESULTS: The plasma levels of IL-6, C3a, and C5a, but not of MMP-9 and TIMP-1, were significantly higher in women with SPTD at < 32 weeks than in those who delivered at ≥ 32 weeks. The women who delivered at < 32 weeks had more advanced cervical dilatation, and higher rates of antibiotic and tocolytic administration and were less likely to be given vaginal progesterone than those who delivered at ≥ 32 weeks. Using a stepwise regression analysis, a combined prediction model was developed, which included the plasma IL-6 and C3a levels, and cervical dilatation (area under the curve [AUC], 0.901). The AUC for this model was significantly greater than that for any single variable included in the predictive model. In the univariate analysis, plasma IL-6 level was the only significant predictor of intra-amniotic infection.CONCLUSION: In women with premature cervical dilation or a short cervix, maternal plasma IL-6, C3a, and C5a levels could be useful non-invasive predictors of SPTD at < 32 weeks. A combination of these biomarkers and conventional clinical factors may clearly improve the predictability for SPTD, as compared with the biomarkers alone. An increased plasma level of IL-6 predicted intra-amniotic infection.

OBJECTIVE: Scarce literature about myoma removal without anesthesia has been published. The aim of this paper is to evaluate the feasibility of a new alternative for a hysteroscopic myomectomy in a conventional office setting, without need for anesthesia. METHODS: Step-by-step description of the surgical technique has been provided, based on video images. An office hysteroscopy was performed in a Gynecological Endoscopy Department of a tertiary European hospital. RESULTS: A 49-year-old woman was referred for management of severe hypermenorrhea. Consent and approval were received from the patient and the institutional review board, respectively. The introduction of a Truclear® hysteroscopic polyp morcellator of 5.5 mm with optic of 0 degrees into the uterine cavity did not require any kind of anesthesia or cervical dilatation. The use of saline flow helped distend the cavity and identify a submucosal myoma. Under direct vision, a full myomectomy was performed via mechanical energy with continuous cutting movements, without any complication. After the procedure was completed, the excised material was aspirated through the device into a collecting pouch. A successful complete morcellation of a Type-0 submucosal leiomyoma with a polyp morcellator device was performed in an outpatient setting. Good medical results, good tolerance by the patient besides lower surgical risks due to mechanical instead of electrical energy are shown. CONCLUSION: In conclusion, this video demonstrates that a hysteroscopic myomectomy can be performed successfully in office with lower risk of complications from the procedure and without use of general anesthesia besides good tolerance by the patient.

INTRODUCTION: This study aimed to compare instrumental vaginal deliveries (IDs) and Caesarean sections (CSs) performed at full cervical dilatation, including factors influencing delivery and differences in maternal and neonatal outcomes. METHODS: A retrospective review was conducted of patients who experienced a prolonged second stage of labour at Singapore General Hospital from 2010 to 2012. A comparison between CS and ID was made through analysis of maternal/neonatal characteristics and peripartum outcomes. RESULTS: Of 253 patients who required intervention for a prolonged second stage of labour, 71 (28.1%) underwent CS and 182 (71.9%) underwent ID. 5 (2.0%) of the patients who underwent CS had failed ID. Of the maternal characteristics considered, ethnicity was significantly different. Induction of labour and intrapartum epidural did not influence delivery type. 70.4% of CSs occurred outside office hours, compared with 52.7% of IDs (p = 0.011). CS patients experienced a longer second stage of labour (p < 0.001). Babies born via CS were heavier (p < 0.001), while the ID group had a higher proportion of occipitoanterior presentations (p < 0.001). Estimated maternal blood loss was higher with CSs (p < 0.001), but neonatal outcomes were similar. CONCLUSION More than one in four parturients requiring intervention for a prolonged second stage of labour underwent emergency CS. Low failed instrumentation rates and larger babies in the CS group suggest accurate diagnoses of cephalopelvic disproportion. The higher incidence of CS after hours suggests trainee reluctance to attempt ID. There were no clinically significant differences in maternal and neonatal morbidity.

OBJECTIVE: To determine whether vaginal application of 40 mg isosorbide-5-mononitrate (ISMN) has a comparable cervical ripening efficacy to and lesser side effects than 400 µg misoprostol in women scheduled for the first trimester induced abortion using a manual vacuum aspirator (MVA). METHODS: We conducted a prospective randomized open- label study in 70 women at 6–12 weeks of pregnancy at the R G Kar Medical College and Hospital, Kolkata, India, over a period of two years from 2015 to 2017. Forty milligrams of ISMN and 400 µg misoprostol were vaginally applied for cervical priming. The primary outcome measure was the cervical response assessed by the passage of the appropriate and largest sized MVA cannula through the internal os without resistance, at the beginning of the procedure. RESULTS: The base line cervical dilatation was found to be significantly higher in the misoprostol group than in the ISMN group (7.65±1.38 vs. 6.9±1.26 mm; P=0.025, 95% confidence interval, −1.4046 to −0.953). However, when the women were sub-analyzed based on parity, there was no statistically significant difference in the same parameters among the multigravid women. The need for further cervical dilatation was significantly higher in the ISMN group when the primigravid women were compared, although the multigravid women responded favorably to ISMN. CONCLUSION: In the primigravid women, misoprostol appears to exert a higher efficacy as a cervical ripening agent in contrast to ISMN. However, ISMN can be used in multigravid women for the same purpose as in this group, misoprostol did not show any significant improvement in efficacy over ISMN.

Misoprostol is widely used in daily practice for induction of labor and cervical dilatation prior to intrauterine procedures, including dilatation and curettage or hysteroscopy. Anaphylactic shock to intravaginal misoprostol can occur not only in pregnant women, as reported in 2 previous cases, but also in a non-pregnant, perimenopausal woman, as in the case described herein. A 49-year-old woman received vaginal misoprostol for cervical ripening prior to hysteroscopic myomectomy and experienced anaphylactic shock. Two 400 μg doses of misoprostol 6 hours apart caused uncontrolled shaking and high fever followed by shock. In conclusion, the possibility of anaphylactic shock should be considered in patients with sudden hypotension following misoprostol administration. Prompt identification and management are crucial to prevent morbidity and mortality following an anaphylactic shock to misoprostol.

BackgroundIn the mainland of China, the trial of labor after cesarean section is still a relatively new technique. In this study, we aimed to investigate the effects of labor onset, oxytocin use, and epidural anesthesia on maternal and neonatal outcomes for vaginal birth after cesarean section (VBAC) in a tertiary hospital in China.

MethodsThis was a retrospective study carried out on 212 VBAC cases between January 2015 and June 2017 in Beijing Obstetrics and Gynecology Hospital, Capital Medical University. Relevant data were acquired on a form, including maternal age, gravidity and parity, body mass index before pregnancy, weight gain during pregnancy, type of labor onset, gestational age, the use of oxytocin and epidural anesthesia, birth mode, the duration of labor, and neonatal weight. The factors affecting maternal and neonatal outcomes for cases involving VBAC, especially with regards to postpartum hemorrhage (PPH) and fetal distress, were evaluated by univariate analysis and multivariable logistic regression.

ResultsData showed that 36 women (17.0%) had postpartum hemorrhage (PPH) and 51 cases (24.1%) featured fetal distress. Normal delivery took place for 163 infants (76.9%) while 49 infants (23.1%) underwent operative vaginal deliveries with forceps. There were 178 cases (84.0%) of spontaneous labor and 34 cases (16.0%) required induction. Oxytocin was used in 54 cases (25.5%) to strengthen uterine contraction, and 65 cases (30.7%) received epidural anesthesia. The rate of normal delivery in cases involving PPH was significantly lower than those without PPH (61.1% vs. 80.1%; χ = 6.07, P = 0.01). Multivariate logistic analysis showed that the intrapartum administration of oxytocin (odds ratio [OR] = 2.47; 95% confidence interval [CI] = 1.07-5.74; P = 0.04) and birth mode (OR = 0.40; 95% CI = 0.18-0.87; P = 0.02) was significantly associated with PPH in VBAC cases. Operative vaginal delivery occurred more frequently in the group with fetal distress than the group without (49.0% vs. 14.9%, χ = 25.36, P = 0.00). Multivariate logistic analysis also revealed that the duration of total labor (OR = 1.01; 95% CI = 1.00-1.03; P = 0.04) and the gestational week of delivery (OR = 1.08; 95% CI = 1.05-1.11; P = 0.00) were significantly associated with fetal distress in VBAC.

ConclusionsThe administration of oxytocin during labor and birth was identified as a protective factor for PPH in VBAC while birth mode was identified as a risk factor. Finally, the duration of total labor and the gestational week of delivery were identified as risk factors for fetal distress in cases of VBAC. This information might help obstetricians provide appropriate interventions during labor and birth for VBAC.

BACKGROUND: Pre-induction of labor cervical ripening increases success of labor induction when there is unfavorable cervix. Evening primrose oil soft gel capsule contains linoleic and gamma-linolenic acid, which are precursors of prostaglandins E1 andE2.
OBJECTIVE: To measure the effectiveness of evening primrose oil capsule as a cervical ripening agent by measuring the Bishop score before and 4 hours after intravaginal insertion of six capsules.
METHODS: A quasi-experimental cross-sectional study was conducted from the period of May to July 2016 involving labor induction patients with a Bishop score ?4, an intact amniotic sac and a Biophysical profile score of 10/10 or 8/8.
RESULTS: Thirteen patients had an average age of 27±6 years, and a mean age of gestation of 40±1 weeks. Seven patients (54%) were nulliparous, 2 (15%) were primiparous and 4 (31%) were multiparous. Seven patients (54%) had hypertension, 1 (8%) had diabetes mellitus, 5 (38%) had post-term pregnancies. A paired t-test was done to check for statistically significant changes in the Bishop score. Change in the Bishop score from baseline to 4 hours after insertion of evening primrose oil capsules was statistically significant (p=0.001). Eleven patients (85%) had improvement in the Bishop score after 4 hours, 4 (31%) of which had a clinically significant change in the Bishop score (?4). Specifically, there were statistically significant changes in the dilatation (p=0.027), effacement (p=0.006) and consistency (p=0.002). The mean birth weight of deliveries was 3192±351 grams. Nine patients (69%) underwent primary low segment cesarean section, six (46%) of which for nonreassuring fetal status, 2 (15%) for arrest in cervical dilatation, and 1 (8%) for intraamnionic infection. Four patients (31%) successfully delivered vaginally.
CONCLUSION: Results showed a positive effect on the Bishop score during cervical ripening although further studies are needed to establish direct correlation.

BACKGROUND: Pyometra should be treated with caution in elderly patients because it may indicate a malignancy in the post-menopausal period and can result in life-threatening complications such as septicemia or pan-peritonitis. METHODS: We retrospectively analyzed the clinical features of 30 patients aged ≥65 years who received treatment for pyometra between January 2010 and December 2014. RESULTS: The 30 patients (age: median, 74 years; range, 66-88 years) were evaluated. They presented with vaginal discharge (n=17), vaginal bleeding (n=8), abdominal pain (n=6), or fever (n=3). The most common accompanying systemic disease was hypertension (n=15), followed by diabetes mellitus (n=10). Of the 30 cases, seven were associ- ated with gynecologic malignancy (cervical cancers, n=3; endometrial cancers, n=3; and ovarian cancer, n=1); and 14, with gynecologic benign diseases (uterine myoma, n=5; cervical intraepithelial neoplasia, n=4; tubo-ovarian abscess, n=3; endometrial polyp, n=1; uterine prolapse, n=1). All the patients were treated with cervical dilatation and drainage. Fifteen patients underwent gynecologic surgery with antibiotic therapy, and 15 received empirical antibiotic treatment alone. Two women experienced spontaneous perforation of pyometra. Pyometra is considered a complication of benign and malignant gynecologic disease, until proven otherwise. CONCLUSION: In elderly patients with comorbidities, pyometra might induce severe complications such as pan-peritonitis or sepsis. Early accurate diagnosis is important to determine an appropriate individualized treatment to reduce morbidity and mortality.

OBJECTIVE: To assess the efficacy and safety of vaginal misoprostol after a pretreatment with vaginal estradiol to facilitate the hysteroscopic surgery in postmenopausal women. METHODS: In this observational comparative study, 35 control women (group A) did not receive any pharmacological treatment,26 women (group B) received 25 µg of vaginal estradiol daily for 14 days and 400 µg of vaginal misoprostol 12 hours before hysteroscopic surgery, 32 women (group C) received 400 µg of vaginal misoprostol 12 hours before surgery. RESULTS: Demographic data were well balanced and all variables were not significantly different among the three groups. The study showed a significant difference in the preoperative cervical dilatation among the group B (7.09±1.87 mm), the group A (5.82±1.85 mm; B vs. A, P=0.040) and the group C (5.46±2.07 mm; B vs. C, P=0.007). The dilatation was very easy in 73% of women in group B. The pain scoring post surgery was lower in the group B (B vs. A, P=0.001; B vs. C, P=0.077). In a small subgroup of women with suspected cervical stenosis, there were no statistically significant differences among the three groups considered. No complications during and post hysteroscopy were observed. CONCLUSION: In postmenopausal women the pretreatment with oestrogen appears to have a crucial role in allowing the effect of misoprostol on cervical ripening. The combination of vaginal estradiol and vaginal misoprostol presents minor side effects and has proved to be effective in obtaining satisfying cervical dilatation thus significantly reducing discomfort for the patient.
