To determine whether obstetric units in the UK comply with the recommendations by the National Institute for Clinical Excellence (NICE) on the maximum doses of intravaginal prostaglandin for induction of labour, a cross-sectional telephone survey of all obstetric units in the UK listed on Dr Foster's website was undertaken. The maximum doses recommended by NICE were exceeded by 86.4% (76/88) and 61.1% (55/90) of units that use intravaginal prostaglandin tablet and intravaginal prostaglandin gel, respectively. Units that use prostaglandin tablets were four times more likely to exceed the recommended maximum dose (OR = 4.03, 95% CI, 1.9 - 8.4), six times more likely to use 50% or more of the recommended maximum dose for nulliparous women (OR = 5.9, 95% CI, 3.1 - 11.0), and six times more likely to use 50% or more of the recommended maximum dose for multiparous women (OR = 6.5, 95% CI, 3.0 - 13.9). A majority of obstetric units in the UK exceed the maximum doses of intravaginal prostaglandin recommended by NICE for induction of labour. 相似文献

Study ObjectiveTo characterize obstetric outcomes for concomitant Asherman syndrome and adenomyosis.DesignA retrospective cohort study.SettingA community teaching hospital affiliated with a large academic medical center.PatientsA total of 227 patients with Asherman syndrome with available hysteroscopy and pelvic ultrasound reports.InterventionsTelephone survey to assess and compare the obstetric outcomes of patients with Asherman syndrome with concomitant adenomyosis (Group A) vs patients with Asherman syndrome without concomitant adenomyosis (Group B).Measurements and Main ResultsA telephone survey and confirmatory chart review were conducted to obtain information on patients’ demographics, gynecologic and obstetric history, past medical and surgical history, and Asherman syndrome management. Adenomyosis was a common sonographic finding, detected in 39 patients with Asherman syndrome (17.2%). In this cohort, 77 patients attempted pregnancy and produced 87 pregnancies. Age (odds ratio [OR] 0.67; 95% confidence intervals [CI], 0.52–0.86) was negatively associated with a pregnancy outcome. Age (OR 0.83; 95% CI, 0.73–0.95) and severe Asherman disease (OR 0.06; 95% CI, <0.01–0.99) were negatively associated with a live birth outcome. Adenomyosis was not an independent predictor of pregnancy rate, miscarriage rate, or live birth rate among patients with Asherman syndrome.ConclusionAdenomyosis is relatively common in patients with Asherman syndrome. Adenomyosis does not seem to add any distinct detriment to fertility among patients with Asherman syndrome. 相似文献

BACKGROUND: Twin pregnancies constitute 25% of all in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies. There is a lack of knowledge on maternal risks and perinatal outcome of IVF/ICSI twin pregnancies. METHODS: National survey by questionnaire (n = 1769). The study population consisted of all IVF/ICSI twin mothers (n = 266) and the two control groups of all IVF/ICSI singleton mothers (n = 764) and non-IVF/ICSI twin mothers (n = 739) who delivered in Denmark in 1997. The response rate was 89% among IVF twin mothers and overall 81%. RESULTS: In terms of maternal risks and perinatal outcome no significant differences were observed between IVF/ICSI twin and non-IVF/ICSI twin pregnancies after stratification for maternal age and parity. Nevertheless, IVF/ICSI twin mothers were more frequently on sick leave (OR 2.5, 95% CI 1.5-4.0) and hospitalized (OR 1.9, 95% CI 1.3-2.8) during pregnancy. Compared with IVF/ICSI singleton pregnancies, IVF/ICSI twin pregnancies were characterized by a higher incidence of preeclampsia (OR 2.4, 95% CI 1.5-4.2) and a higher frequency of sick leave (OR 6.8, 95% CI 4.4-10.5) and hospitalizations during pregnancy (OR 3.5, (95% CI 2.5-4.9); moreover, mean birthweight (p < 0.001) and gestational age (p < 0.001) were lower. No differences were observed in the incidence of pregnancy-induced hypertension and gestational diabetes between IVF/ICSI twin and singleton pregnancies. CONCLUSION: Although this population study indicates that maternal risks in IVF/ICSI twin pregnancies are comparable with non-IVF/ICSI twin pregnancies, the IVF/ICSI twin mothers were more likely to be on sick leave or hospitalized during pregnancy. Furthermore, maternal risks were higher and obstetric outcome poorer in IVF/ICSI twin vs. IVF/ICSI singleton pregnancies. 相似文献

BACKGROUND: One of the major indications for Cesarean section (CS) is failure of labor to progress. This study was aimed at defining obstetric risk factors for failure of labor to progress during the first stage, and to determine pregnancy outcome. METHODS: A population-based study comparing all singleton, vertex, term deliveries between the years 1988 and 1999 with an unscarred uterus, complicated with failure of labor to progress during the first stage with deliveries without non-progressive labor (NPL). Multiple logistic regression analysis was performed to investigate independent obstetric risk factors associated with failure of labor to progress during the first stage. RESULTS: Failure to progress during the first stage of labor complicated 1.3% (n = 1197) of all deliveries included in the study (n = 92 918), and resulted in CS. Independent risk factors for failure of labor to progress during the first stage, using a multivariable analysis, were premature rupture of membranes (PROM; OR = 3.8, 95% CI 3.2-4.5), nulliparity (OR = 3.8, 95% CI 3.3-4.3), labor induction (OR = 3.3, 95% CI 2.9-3.7), maternal age > 35 years (OR = 3.0, 95% CI 2.6-3.6), birth weight > 4 kg (OR = 2.2, 95% CI 1.8-2.7), hypertensive disorders (OR = 2.1, 95% CI 1.8-2.6), hydramnios (OR = 1.9, 95% CI 1.5-2.3), fertility treatment (OR = 1.8, 95% CI 1.4-2.4), epidural analgesia (OR = 1.6, 95% CI 1.4-1.8) and gestational diabetes (OR = 1.4, 95% CI 1.1-1.7). Although newborns delivered after failure of labor to progress during the first stage had significantly higher rates of Apgar scores lower than 7 at 1 and 5 min as compared with the controls (18.2% vs. 2.1%; P < 0.001 and 1.3% vs. 0.2%; P < 0.001, respectively), no significant differences were noted between the groups regarding perinatal mortality (0.3% vs. 0.4%; P = O.329). Maternal anemia and accordingly packed cells transfusion (47.4% vs. 22.8%; P < 0.001 and 5.6% vs. 1.0%; P < 0.001, respectively) were higher among pregnancies complicated with failure of labor to progress during the first stage as compared with the controls. CONCLUSIONS: Major risk factors for failure of labor to progress during the first stage were PROM, nulliparity, induction of labor and older maternal age. Indications for labor induction should be carefully evaluated in order to decrease the rate of operative deliveries. 相似文献

OBJECTIVE: To determine the incidence of, and obstetric risk factors for, emergency peripartum hysterectomy. STUDY DESIGN: A population-based study comparing all singleton deliveries between the years 1988 and 1999 that were complicated with peripartum hysterectomy to deliveries without this complication. Statistical analysis was performed with multiple logistic regression analysis. RESULTS: Emergency peripartum hysterectomy complicated 0.048% (n = 56) of deliveries in the study (n = 117,685). Independent risk factors for emergency peripartum hysterectomy from a backward, stepwise, multivariable logistic regression model were: uterine rupture (OR = 521.4, 95% CI 197.1-1379.7), placenta previa (OR = 8.2, 95% CI 2.2-31.0), postpartum hemorrhage (OR = 33.3, 95% CI 12.6-88.1), cervical tears (OR = 18.0, 95% CI 6.2-52.4), placenta accreta (OR = 13.2, 95% CI 3.5-50.0), second-trimester bleeding (OR = 9.5, 95% CI 2.3-40.1), previous cesarean section (OR = 6.9, 95% CI 3.7-12.8) and grand multiparity (> 5 deliveries) (OR = 3.4, 95% CI 1.8-6.3). Newborns delivered after peripartum hysterectomy had lower Apgar scores (< 7) at 1 and 5 minutes than did others (OR = 11.5, 95% CI 6.2-20.9 and OR = 27.4, 95% CI 11.2-67.4, respectively). In addition, higher rates of perinatal mortality were noted in the uterine hysterectomy vs. the comparison group (OR = 15.9, 95% CI 7.5-32.6). Affected women were more likely than the controls to receive packed-cell transfusions (OR = 457.7, 95% CI 199.2-1105.8) and had lower hemoglobin levels at discharge from the hospital (9.9 +/- 1.3 vs. 12.8 +/- 5.7, P < .001). CONCLUSION: Cesarean deliveries in patients with suspected placenta accreta, specifically those performed due to placenta previa in women with a previous uterine scar, should involve specially trained obstetricians. In addition, detailed informed consent about the possibility of emergency peripartum hysterectomy and its associated morbidity should be obtained. 相似文献

OBJECTIVES: To determine obstetric risk factors and perinatal outcomes of pregnancies complicated by umbilical cord prolapse. METHODS: A population-based study was performed comparing all deliveries complicated by cord prolapse to deliveries without this complication. Statistical analysis was performed using multiple logistic regression models. RESULTS: Prolapse of the umbilical cord complicated 0.4% (n=456) of all deliveries included in the study (n=121,227). Independent risk factors for cord prolapse identified by a backward, stepwise multivariate logistic regression model were: malpresentation (OR=5.1; 95% CI 4.1-6.3), hydramnios (OR=3.0; 95% CI 2.3-3.9), true knot of the umbilical cord (OR=3.0; 95% CI 1.8-5.1), preterm delivery (OR=2.1; 95% CI 1.6-2.8), induction of labor (OR=2.2; 95% CI 1.7-2.8), grandmultiparity (>five deliveries, OR=1.9; 95% CI 1.5-2.3), lack of prenatal care (OR=1.4; 95% CI 1.02-1.8), and male gender (OR=1.3; 95% CI 1.1-1.6). Newborns delivered after umbilical cord prolapse graded lower Apgar scores, less than 7, at 5 min (OR=11.9, 95% CI 7.9-17.9), and had longer hospitalizations (mean 5.4+/-3.5 days vs. 2.9+/-2.1 days; P<0.001). Moreover, higher rates of perinatal mortality were noted in the cord prolapse group vs. the control group (OR=6.4, 95% CI 4.5-9.0). Using a multiple logistic regression model controlling for possible confounders, such as preterm delivery, hydramnios, etc., umbilical cord prolapse was found to be an independent contributing factor to perinatal mortality. CONCLUSIONS: Prolapse of the umbilical cord is an independent risk factor for perinatal mortality. 相似文献

BACKGROUND: It has been suggested that a history of subfertility is associated with increased obstetric and perinatal risks. It is unclear if the cause is inherent characteristics in the women or the fertility treatment. OBJECTIVES: To compare the obstetric and perinatal risks of singleton pregnancies in women with a history of subfertility in comparison with the general population. DESIGN: Population cohort. SETTING: Aberdeen, Scotland. POPULATION: Cases were women attending the Fertility Clinic between 1989 and 1999 who subsequently went on to have singleton pregnancies. Controls included the general population of women who delivered singletons over the same period. METHODS: We performed a retrospective cohort study to investigate the obstetric outcome of singleton pregnancies in women with subfertility. The general population of women who delivered singletons over the same period served as controls. MAIN OUTCOME MEASURES: Obstetric and perinatal complications in singleton pregnancies. RESULTS: Maternity records were available for a total of 1437 subfertile women and 21,688 controls. Subfertile women were older [mean (SD) age: 31 (4.7) years vs 27 (5.4) years, P < 0.01] and more likely to be primiparous (70% vs 65%, P < 0.001). After adjusting for age and parity, subfertile women were at increased risk of pre-eclampsia (OR 1.9, 95% CI 1.5-2.5), placenta praevia (OR 3.9, 95% CI 2.2-7.0) and placental abruption (OR 1.8, 95% CI 1.1-3.0), and more likely to undergo induction of labour (OR 1.5, 95% CI 1.3-1.6), caesarean section (OR 2.1, 95% CI 1.8-2.4) and instrumental delivery (OR 2.2, 95% CI 1.8-2.6), and deliver low birthweight (OR 1.4, 95% CI 1.3-1.7) and preterm (OR 1.7, 95% CI 1.2-2.2) infants. There were no differences between treatment-related and treatment-independent pregnancies. CONCLUSION: Subfertile women are at higher risk of obstetric complications, which persist after adjusting for age and parity. 相似文献

Objective: To determine the incidence, obstetric risk factors and perinatal outcome of placenta previa. Study design: All singleton deliveries at our institution between 1990 and 1998 complicated with placenta previa were compared with those without placenta previa. Results: Placenta previa complicated 0.38% ( n = 298) of all singleton deliveries ( n = 78 524). A back-step multiple logistic regression model found the following factors to be independently correlated with the occurrence of placenta previa: maternal age above 40 years (OR 3.1, 95% CI 2.0-4.9), infertility treatments (OR 3.1, 95% CI 1.8-5.6), a previous Cesarean section (OR 1.8, 95% CI 1.4-2.4), a history of habitual abortions (OR 1.3, 95% CI 1.3-2.7) and Jewish ethnicity (OR 1.3, 95% CI 1.1-1.8). Pregnancies complicated with placenta previa had significantly higher rates of second-trimester bleeding (OR 156.0, 95% CI 87.2-277.5), pathological presentations (OR 7.6, 95% CI 5.7-10.1), abruptio placentae (OR 13.1, 95% CI 8.2-20.7), congenital malformations (OR 2.6, 95% CI 1.5-4.2), perinatal mortality (OR 2.6, 95% CI 1.1-5.6), Cesarean delivery (OR 57.4, 95% CI 40.7-81.4), Apgar scores at 5 min lower than 7 (OR 4.4, 95% CI 2.3-8.3), placenta accreta (OR 3.6, 95% CI 1.1-9.9) postpartum hemorrhage (OR 3.8, 95% CI 1.2-10.5), postpartum anemia (OR 5.5, 95% CI 4.4-6.9) and delayed maternal and infant discharge from the hospital (OR 10.9, 95% CI 7.3-16.1) as compared to pregnancies without placenta previa. In a multivariable analysis investigating risk factors for perinatal mortality, the following were found to be independent significant factors: congenital malformations, placental abruption, pathological presentations and preterm delivery. In contrast, placenta previa and Cesarean section were found to be protective factors against the occurrence of perinatal mortality while controlling for confounders. Conclusion: Although an abnormal implantation per se was not an independent risk factor for perinatal mortality, placenta previa should be considered as a marker for possible obstetric complications. Hence, the detection of placenta previa should encourage a careful evaluation with timely delivery in order to reduce the associated maternal and perinatal complications. 相似文献

Mode of delivery and fecal incontinence at midlife: a study of 2,640 women in the Gazel cohort 总被引:1,自引:0,他引:1
OBJECTIVE: To estimate obstetric risk factors of fecal incontinence among middle-aged women. METHODS: We conducted a mail survey of the Gazel cohort of volunteers for epidemiologic research. In 2000, a questionnaire on anal incontinence was mailed to 3,114 women who were then between the ages of 50 and 61 years; 2,640 (85%) women returned the completed questionnaire. Fecal incontinence was defined by involuntary loss of stool. Logistic regression was used to estimate the effect of obstetric and general risk factors. RESULTS: Prevalence of fecal incontinence in the past 12 months was 9.5% (250). Significant risk factors for fecal incontinence were completion of high school (adjusted odds ratio [OR] 1.5, 95% confidence interval [CI] 1.1-2.0), self-reported depression (OR 2.1, 95% CI 1.6-2.7), overweight or obesity measured by body mass index (BMI) (OR 1.5 for BMI of 25-30, 95% CI 1.1-2.0; OR 1.6 for BMI more than 30, 95% CI 1.1-2.5), surgery for urinary incontinence (OR 3.5, 95% CI 2.0-6.1), and anal surgery (OR 1.7, 95% CI 1.1-2.9). No obstetric variable (parity, mode of delivery, birth weight, episiotomy, or third-degree perineal tear) was significant. Prevalence of fecal incontinence was similar for nulliparous, primiparous, secundiparous, and multiparous women (11.3%, 9.0%, 9.0%, and 10.4%, respectively), and among parous women, it was similar for women with spontaneous vaginal, instrumental (at least one), or only cesarean deliveries (9.3%, 10.0%, and 6.6%, respectively). CONCLUSION: In our population of women in their 50s, fecal incontinence was not associated with either parity or mode of delivery. 相似文献

OBJECTIVE: To identify obstetric and other risk factors for urinary incontinence that occurs during pregnancy or after childbirth. DESIGN: Questionnaire survey of women. SETTING: Maternity units in Aberdeen (Scotland), Birmingham (England) and Dunedin (New Zealand). POPULATION: A total of 3405 primiparous women with singleton births delivered during 1 year. METHODS: Questionnaire responses and obstetric case note data were analysed using multivariate analysis to identify associations with urinary incontinence. MAIN OUTCOME MEASURES: Urinary incontinence at 3 months after delivery first starting in pregnancy or after birth. RESULTS: The prevalence of urinary incontinence was 29%. New incontinence first beginning after delivery was associated with older maternal age (oldest versus youngest group, OR 2.02, 95% CI 1.35-3.02) and method of delivery (caesarean section versus spontaneous vaginal delivery, OR 0.28, 95% CI 0.19-0.41). There were no significant associations with forceps delivery (OR 1.18, 95% CI 0.92-1.51) or vacuum delivery (OR 1.16, 95% CI 0.83-1.63). Incontinence first occurring during pregnancy and still present at 3 months was associated with higher maternal body mass index (BMI>25, OR 1.68, 95% CI 1.16-2.43) and heavier babies (birthweight in top quartile, OR 1.56, 95% CI 1.12-2.19). In these women, caesarean section was associated with less incontinence (OR 0.39, 95% CI 0.27-0.58) but incontinence was not associated with age. CONCLUSIONS: Women have less urinary incontinence after a first delivery by caesarean section whether or not that first starts during pregnancy. Older maternal age was associated with new postnatal incontinence, and higher BMI and heavier babies with incontinence first starting during pregnancy. The effect of further deliveries may modify these findings. 相似文献

OBJECTIVE: To identify perinatal factors associated with cerebral palsy (CP). METHODS: This was a case-control study based on the Swedish Medical Birth Registry and the Swedish Hospital Discharge Registry, including 2,303 infants born in Sweden 1984-1998 with a diagnosis of CP and 1.6 million infants without this diagnosis. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. RESULTS: Infants born preterm had a highly increased risk for CP, and constituted 35% of all cases; OR 34 (95% CI 29-39) in weeks 23-27, OR 37 (95% CI 32-42) in weeks 28-29, OR 26 (95% CI 23-30) in weeks 30-31, and OR 3.9 (95% CI 3.4-4.4) in weeks 32-36. Boys had a higher risk (sex ratio 1.36:1), particularly before term (sex ratio 1.55:1). Other factors associated with CP were being small or large for gestational age at birth, abruptio placentae (OR 8.6, 95% CI 5.6-13.3), maternal insulin-dependent diabetes mellitus type 1 (OR 2.1, 95% CI 1.4-3.1), preeclampsia (OR 1.5, 95% CI 1.3-2.4), being a twin (OR 1.4, 95% CI 1.1-1.6), maternal age older than 40 years (OR 1.4, 95% CI 1.1-1.8) or 35-39 years (OR 1.2, 95% CI 1.1-1.4), primiparity (OR 1.2, 95% CI 1.1-1.3), and smoking (OR 1.2, 95% CI 1.1-1.3). In term infants, low Apgar scores were associated with a high risk for CP; OR 62 (95% CI 52-74) at score 6 at 5 minutes, OR 498 (95% CI 458-542) at score 3. Other factors associated with CP in term infants were breech presentation at vaginal birth (OR 3.0, 95% CI 2.4-3.7), instrumental delivery (OR 1.9, 95% CI 1.6-2.3), and emergency cesarean delivery (OR 1.8, 95% CI 1.6-2.0). CONCLUSION: Preterm birth entails a high risk for CP, but 65% of these children are born at term. Several obstetric factors and low Apgar scores are associated with CP. LEVEL OF EVIDENCE: II-2. 相似文献

Study ObjectiveThe findings of previous studies have been inconsistent as to whether benign hysterectomy via minimally invasive laparoscopic surgery increases the risk of vesicoureteral injury when compared with laparotomy. The objectives of our study were to (1) examine the rate of vesicoureteral injury on benign hysterectomy by the surgical approach and (2) compare the risk of vesicoureteral injury specifically between minimally invasive laparoscopic and abdominal hysterectomy on a populational level.DesignRetrospective population-based observational study.SettingThe National Inpatient Sample.PatientsA total of 501 110 women who had undergone hysterectomy for benign gynecologic disease between January 2012 and September 2015 were included as follows: total abdominal hysterectomy (TAH, n = 284 365 [56.7%]), total laparoscopic hysterectomy (TLH, n = 60 410 [12.1%]), abdominal supracervical hysterectomy (Abd-SCH, n = 55 655 [11.1%]), laparoscopic-assisted vaginal hysterectomy (LAVH, n = 45 620 [9.1%]), total vaginal hysterectomy (TVH, n = 34 865 [7.0%]), and laparoscopic supracervical hysterectomy (LSC-SCH, n = 20 195 [4.0%]).InterventionsA comprehensive risk assessment for vesicoureteral injury by hysterectomy mode was performed, adjusting for patient demographics and gynecologic disease types. Propensity score inverse probability of treatment weighing was used to compare (1) TLH versus TAH and (2) LSC-SCH versus Abd-SCH with generalized estimating equations. In a sensitivity analysis, gynecologic disease−specific injury risk and vaginal route−specific injury risk (LAVH vs TVH) were assessed.Measurements and Main ResultsVesicoureteral injury was reported in 1045 (0.21%) women overall. LAVH (0.28%) had the highest bladder injury rate, whereas LSC-SCH had the lowest (0.10%) (p <.001). TLH (0.13%) had the highest ureteral injury rate, whereas TAH had the lowest (0.04%) (p <.001). In propensity score inverse probability of treatment weighing models, compared with TAH, TLH was associated with an increased risk of ureteral injury (odds ratio [OR] 3.95, 95% confidence interval [CI] 2.03−7.67, p <.001) but not bladder injury (OR 1.04, 95% CI 0.57−1.90, p = .897). Risk of ureteral injury was particularly high when TLH was performed for endometriosis (OR 6.15, 95% CI 1.18−31.9, p = .031) or for uterine myoma (OR 4.15, 95% CI 2.13−8.11, p <.001). In contrast, for supracervical or vaginal hysterectomy, minimally invasive laparoscopic approaches were not associated with an increased risk of vesicoureteral injury (LSC-SCH vs Abd-SCH: OR 0.62, 95% CI 0.19−1.98, p = .419; LAVH vs TVH: OR 1.21, 95% CI 0.63−2.33, p = .564).ConclusionThe risk of vesicoureteral injury on benign hysterectomy is low overall regardless of hysterotomy modalities but varies widely with the surgical approach.

OBJECTIVE: To describe the obstetric characteristics and neonatal outcomes in unplanned out-of-hospital deliveries. STUDY DESIGN: Obstetric characteristics and neonatal outcomes were compared between 151 consecutive parturients with unplanned, out-of-hospital term deliveries and 151 hospital term deliveries. RESULTS: Women who delivered out of hospital tended to be older (32 +/- 5.5 vs. 28 +/- 5.0 years, p = 0.046) and less educated (4.4 +/- 5.1 vs. 6.5 +/- 5.0 years, p = 0.005) as compared to women who delivered in the hospital. Unplanned out-of-hospital deliveries resulted in statistically significant higher rate of low-birth-weight newborns (< 2,500 g) (OR= 3.9, 95% CI 2.0-7.7, p<0.001), postpartum hemorrhage (OR = 8.4, 95% CI 1.1-181.1, p = 0.018) and trended for higher rate of manual lysis of retained placenta and membranes (4.0% vs. 0%, p = 0.013). Higher rates of admission to the neonatal intensive care unit due to neonatal complications, such as polycythemia (12.6% vs. 0%, p < 0.001), hypoglycemia (9.3% vs. 0.6%, p = 0.001) and convulsions (3.3% vs. 0%, p = 0.024), were noted in the out-of-hospital delivery group as compared to the controls. Using a multivariable analysis, lower educational level (OR = 0.4, 95% CI 0.3-0.4, p < 0.001), maternal age > 35 (OR = 6.2, 95% CI 2.3-16.7, p < 0.001) and high parity (OR = 7.9, 95% CI 4.9-12.9, p<0.001) were found to be independent risk factors for an unplanned outof hospital delivery. CONCLUSION: Unplanned out-of-hospital birth is an important risk factor for such complications as postpartum hemorrhage, low birth weight and adverse neonatal outcome. 相似文献

OBJECTIVE: To determine the relationship between epidural analgesia and episiotomy usage and episiotomy extension in parturients delivering vaginally. METHODS: A database of 20 888 women experiencing spontaneous vaginal delivery at Grady Memorial Hospital from 1990 to 1995 was examined to identify those receiving epidural analgesia. Patients who underwent epidural catheter placement and had adequate perineal anesthesia at delivery comprised the epidural group, and all others comprised the control group. Demographic characteristics and obstetric outcomes were compared. Univariate and multivariate analyses were used to test the association between epidural analgesia, rates of episiotomy and episiotomy extension. RESULTS: Of the 20888 women experiencing spontaneous vaginal deliveries 6785 (32.5%) received epidural analgesia. Women receiving epidural analgesia were more likely than those not receiving epidural analgesia to be African-American and nulliparous, and to have an occiput posterior presentation. Women receiving epidural analgesia were also more likely to receive an episiotomy (27.8% vs. 13.1%, odds ratio (OR) 2.56, 95% confidence interval (CI) 2.38-2.75) and were less likely to experience a second-degree perineal laceration (11.6% vs. 14.4%, OR 0.75, 95% CI 0.69-0.82) or a third- or fourth-degree extension (8.9% vs. 12.4%, OR 0.81, 95% CI 0.68-0.97). When the results were adjusted for nulliparity, posterior presentation, macrosomia, shoulder dystocia and prolonged second stage, epidural analgesia remained independently associated with receipt of episiotomy (OR 1.97, 95% CI 1.88-2.06) and reduced episiotomy extension (OR 0.74, 95% CI 0.54-0.94). CONCLUSION: Epidural analgesia increases the rates of episiotomy use, and decreases the rate of episiotomy extension, independently of clinical factors associated with episiotomy. 相似文献

OBJECTIVE: To define obstetrical risk factors for arrest of descent during the second stage of labor and to determine perinatal outcome. STUDY DESIGN: All singleton, vertex, term deliveries with an unscarred uterus, between the years 1988 and 1999 were included. Univariable and multivariable analysis were performed to investigate independent risk factors associated with arrest of descent during the second stage of labor and the perinatal outcome. RESULTS: The study included 93266 deliveries, of these 1545 (1.7%) were complicated with arrest of descent during the second stage of labor. Using a multivariable analysis, the following obstetric risk factors were found to be significantly associated with arrest of descent: nulliparity (OR=7.8, 95% CI=6.9-8.7; P<0.001), birth weight >4 kg (OR=2.3, 95% CI=1.9-2.8; P<0.001), epidural analgesia (OR=1.8, 95% CI=1.6-2.0; P<0.001), hydramnios (OR=1.6, 95% CI=1.3-2.0; P<0.001), hypertensive disorders (OR=1.5, 95% CI=1.3-1.8; P<0.001), gestational diabetes A1 and A2 (OR=1.5, 95% CI=1.2-1.8; P<0.001), male gender (OR=1.4, 95% CI=1.2-1.5; P<0.001), premature rupture of membranes (PROM, OR=1.3, 95% CI=1.04-1.6; P=0.021), and induction of labor (OR=1.2, 95% CI=1.02-1.4; P=0.030). Deliveries complicated by arrest of descent resulted in cesarean section in 20.6%, vacuum extraction in 74.0%, and forceps delivery in 5.4%. Newborns delivered after arrest of descent during the second stage of labor had significantly higher rates of low Apgar scores (<7) at 1 and 5 min, as compared to the controls (12.7 vs. 2.1%, P<0.001; and 0.9 vs. 0.2%, P<0.001, respectively). Nevertheless, no significant differences were noted between the groups regarding perinatal mortality (0.38 vs. 0.44%; P=0.759). CONCLUSIONS: Major risk factors for arrest of descent during the second stage of labor were nulliparity, fetal macrosomia, epidural analgesia, hydramnios, hypertensive disorders and gestational diabetes mellitus. These risk factors should be carefully evaluated during pregnancy in order to actively manage high-risk pregnancies. 相似文献

OBJECTIVE: To determine whether cesarean and operative vaginal deliveries are associated with an increased risk of maternal rehospitalization compared with spontaneous vaginal delivery. METHODS: A population-based cohort study was conducted by using the Canadian Institute for Health Information's Discharge Abstract Database between 1997/1998 and 2000/2001, which included 900,108 women aged 15-44 years with singleton live births (after excluding several selected obstetric conditions). RESULTS: A total of 16,404 women (1.8%) were rehospitalized within 60 days after initial discharge. Compared with spontaneous vaginal delivery (rate 1.5%), cesarean delivery was associated with a significantly increased risk of postpartum readmission (rate 2.7%, odds ratio [OR] 1.9, 95% confidence interval [CI] 1.8-1.9); ie, there was 1 excess postpartum readmission per 75 cesarean deliveries. Diagnoses associated with significantly increased risks of readmission after cesarean delivery (compared with spontaneous vaginal delivery) included pelvic injury/wounds (rate 0.86% versus 0.06%, OR 13.4, 95% CI 12.0-15.0), obstetric complications (rate 0.23% versus 0.08%, OR 3.0, 95% CI 2.6-3.5), venous disorders and thromboembolism (rate 0.07% versus 0.03%, OR 2.7, 95% CI 2.1-3.4), and major puerperal infection (rate 0.45% versus 0.27%, OR 1.8, 95% CI 1.6-1.9). Women delivered by forceps or vacuum were also at an increased risk of readmission (rates 2.2% and 1.8% versus 1.5%; OR forceps: 1.4, 95% CI 1.3-1.5; OR vacuum: 1.2, 95% CI 1.2-1.3, respectively). Higher readmission rates after operative vaginal delivery were due to pelvic injury/wounds, genitourinary conditions, obstetric complications, postpartum hemorrhage, and major puerperal infection. CONCLUSION: Compared with spontaneous vaginal delivery, cesarean delivery, and operative vaginal delivery increase the risk of maternal postpartum readmission. LEVEL OF EVIDENCE: II-2. 相似文献

The effect of a peer counseling program on breastfeeding initiation and longevity in a low-income rural population. 总被引:4,自引:0,他引:4
Breastfeeding rates among low-income women in the east-south-central United States are among the lowest in the country. This study examined the effect of a peer counseling program on breastfeeding initiation and duration in a low-income rural population in West Tennessee. A postpartum survey and chart review were conducted with WIC clients at nine health departments. Response rate was 99% (291/293). Breastfeeding initiation and duration at 6 weeks were increased in the peer counselor group (n = 156) compared with women in the no-peer counselor group (n = 135) (53% vs. 33%, p < 0.001, and 26% vs. 13%, p = 0.006, respectively). Multivariate analysis revealed that women in the peer counselor group were significantly more likely to initiate breastfeeding (OR = 2.43, 95% CI = 1.23-4.67) and to be breastfeeding at 6 weeks (OR = 2.78, 95% CI = 2.08-9.51), than those in the no-peer counselor group. 相似文献

Introduction: We evaluated the quality of basic obstetric care provided by Mexican general physicians, obstetric nurses, and professional midwives compared with World Health Organization (WHO) guidelines for evidence‐based practices and national guidelines. Methods: Vaginal births were observed in 5 hospitals in 5 states from June 2006 until July 2007. We created 5 indices based on WHO guidelines and national standards for care during normal birth. These indices included 1) favorable practices at admission, 2) favorable practices during labor, birth, and immediately postpartum, 3) harmful or excessively used practices, 4) newborn practices, and 5) obstetric outcomes. We assessed each provider type's performance as high or low compared with the WHO standard and performed bivariate and multivariate logistic regression analyses to assess the association between indices, patient characteristics, and provider type, adjusting for standard errors for intragroup correlation. Results: We observed 876 independently managed vaginal births. Adjusted regression analyses compared with the general physicians standard revealed significant results for favorable care by obstetric nurses on admission (odds ratio [OR] 6.25; 95% confidence interval [CI], 2.08‐18.84); for care by professional midwives (OR 21.08; 95% CI, 4.24‐104.94) and obstetric nurses (OR 7.88; 95% CI, 2.76‐22.52) during labor, birth, and postpartum; and for newborn practices by obstetric nurses (OR 4.14; 95% CI, 1.08‐15.90). Professional midwives were least likely to perform harmful/excessively used practices during labor, birth, and the postpartum period (OR 0.06; 95% CI, 0.00‐0.35). Discussion: Professional midwives and obstetric nurses perform equally or better than general physicians when assessed by use or misuse of evidence‐based practices. Professional midwives are an underutilized resource in Mexico. If integrated into the mainstream Mexican health system, they may improve the quality of obstetric care. 相似文献
