Objective: To determine factors influencing separation and infectious type wound complications (WCs) in morbidly obese women undergoing primary cesarean delivery (CD). Methods: Retrospective cohort study evaluating infectious and separation WC in morbidly obese (body mass index [BMI] > 35 kg/m2) women undergoing primary CD between January 1994 and December 2008. Chi-square, Fisher’s exact and Student’s t tests used to assess associated factors; backward logistic regression to determine unadjusted and adjusted odds ratios. Results: Of 623 women, low transverse skin incisions were performed in 588 (94.4%), vertical in 35 (7%). Overall WC rate was 13.5%, which varied by incision type (vertical 45.7% vs. 11.6% transverse; p < 0.01), but not BMI class. Incision type and unscheduled CD were associated with infection risk, while incision type, BMI, race and drain use were associated with wound separation. Conclusion: In morbidly obese women both infectious and separation type WC are more common in vertical than low transverse incisions; therefore transverse should be preferred. 相似文献

Weiss JL Malone FD Emig D Ball RH Nyberg DA Comstock CH Saade G Eddleman K Carter SM Craigo SD Carr SR D'Alton ME;FASTER Research Consortium 《American journal of obstetrics and gynecology》2004,190(4):1091-1097
OBJECTIVE: This study was undertaken to determine whether obesity is associated with obstetric complications and cesarean delivery. METHODS: A large prospective multicenter database was studied. Subjects were divided into 3 groups: body mass index (BMI) less than 30 (control), 30 to 34.9 (obese), and 35 or greater (morbidly obese). Groups were compared by using univariate and multivariable logistic regression analyses. RESULTS: The study included 16,102 patients: 3,752 control, 1,473 obese, and 877 morbidly obese patients. Obesity and morbid obesity had a statistically significant association with gestational hypertension (odds ratios [ORs] 2.5 and 3.2), preeclampsia (ORs 1.6 and 3.3), gestational diabetes (ORs 2.6 and 4.0), and fetal birth weight greater than 4000 g (ORs 1.7 and 1.9) and greater than 4500 g (ORs 2.0 and 2.4). For nulliparous patients, the cesarean delivery rate was 20.7% for the control group, 33.8% for obese, and 47.4% for morbidly obese patients. CONCLUSION: Obesity is an independent risk factor for adverse obstetric outcome and is significantly associated with an increased cesarean delivery rate. 相似文献

OBJECTIVE: We sought to determine whether pregnancy outcome differs between obese and morbidly obese GDM patients and to assess pregnancy outcome in association with mode of treatment and level of glycemic control. METHODS: A cohort study of 4,830 patients with gestational diabetes (GDM), treated in the same center using the same diabetic protocol, was performed. Obesity was defined as prepregnancy BMI >30 and <35 kg/m(2); morbid obesity was defined as prepregnancy BMI >or=35 kg/m(2). Well-controlled GDM was defined as mean blood glucose <105 mg/dl. Pregnancy outcome measures included the rates of large for gestational age (LGA) and macrosomic babies, metabolic complications, the need for NICU admission and/or respiratory support, rate of shoulder dystocia, and the rate of cesarean section. RESULTS: Among the GDM patients, the rates of obesity and morbid obesity were 15.7% (760 out of 4830, BMI: 32.4+/-1.6 kg/m(2)) and 11.6% (559 out of 4830, BMI: 42.6+/-2.2 kg/m(2)), respectively. No differences were found with regard to maternal age, ethnicity, gestational age at delivery or oral glucose tolerance test (OGTT) results. Moreover, similar rates of cesarean section, fetal macrosomia, shoulder dystocia, composite outcome, and metabolic complications were noted. Insulin treatment was initiated for 62% of the obese and 73% of the morbidly obese GDM patients (P<0.002). Similar rates of obese and morbidly obese patients achieved desired levels of glycemic control (63% versus 61%, respectively). In both obese and morbidly obese patients who achieved a desired level of glycemic control (<105 mg/dl), no difference was found in pregnancy outcome except that both neonatal metabolic complications and composite outcomes were more prevalent in diet-treated subjects in comparison to insulin-treated GDM patients. CONCLUSION: In obese women with GDM, pregnancy outcome is compromised regardless of the level of obesity or treatment modality. 相似文献

Objective
To study the outcomes of two-stage GDM screening of morbidly obese women in our obstetric unit and to evaluate the diagnostic performance of 20-week oral glucose tolerance test (OGTT) values in predicting or excluding late onset GDM.Study design
A retrospective study in which 190 pregnant women with BMI ≥40 had two-stage screening: a 75 g OGTT is performed at 20 weeks and repeated at 28 weeks if the 20-week OGTT was normal. Receiver operating characteristic (ROC) curves for 20-week OGTT values were constructed in order to obtain an optimal cut-off value of fasting and/or 2-h glucose at 20 weeks from which GDM could be predicted or excluded at 28 weeks. Sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were determined for each of the fasting and 2-h post-load glucose values at 20 weeks.Results
Forty six (24%) women were diagnosed with GDM. Thirty-two (70%) were diagnosed at 20 weeks and 14 (30%) at 28 weeks. The 2-h cut-off value of ≥6 mmol/l at the 20-week OGTT had a negative likelihood ratio of 0.12 to predict GDM at 28 weeks. The low negative likelihood ratio reduces the probability of detecting GDM at 28 weeks from 9% (pre-test probability) to 1% (post-test probability).Conclusion
Nearly 70% of the women were diagnosed with GDM at 20 weeks, which gives an early opportunity to treat maternal hyperglycaemia with consequent health benefits. A 2-h cut-off glucose value of 6 mmol/l at 20 weeks OGTT has a low negative likelihood ratio which virtually excludes GDM at 28 weeks. Hence women with a 2 h value of <6 mmol/l at 20 weeks can avoid a repeat 28 week OGTT test. 相似文献6.

Purpose: Our goal was to compare composite neonatal and maternal morbidities (composite neonatal morbidity (CNM), composite maternal morbidity (CMM)) among deliveries with small for age (SGA) versus appropriate for gestational age (AGA; birthweight 10–89%) among obese versus non-obese women undergoing repeat cesarean delivery (CD).Study design: This is a secondary analysis of a prospective observational study. Women who had elective CD ≥37 weeks were studied. We excluded multiple gestations, fetal anomalies,?>?1 prior CD, and medical diseases. Patients were divided into BMI ≥30 versus <30?kg/m2. CNM included respiratory distress syndrome, necrotizing enterocolitis, severe intraventricular hemorrhage, seizure, or death; CMM included transfusion, hysterectomy, operative injury, coagulopathy, thromboembolism, pulmonary edema, or death. Multivariate logistic regression was used to control for confounding factors.Results: Of 7561 women, we included 65% were obese and 35% were not. SGA rates differed significantly: 8 versus 12% (p?.001). Overall, CNM was significantly higher in patients with SGA versus AGA (adjusted odds ratio (aOR) 2.04, 95% CI 1.19–3.49). CMM of SGA in obese versus non-obese was statistically different (aOR 0.11, 95% CI 0.02–0.68). Among obese mothers, SGA neonates had significantly higher CNM compared with AGA ones (aOR 2.17, 95% CI 1.03–4.59).Conclusions: SGA occurred in 8% of low-risk obese women with prior CD. CNM of SGA babies in obese versus non-obese women were similar. Paradoxically, CMM was lower in obese cases, possibly reflecting the caution that obese patients receive preoperatively. Our findings may assist in counseling patients and designing trials. 相似文献

Objective
To compare the rates of intraoperative and postoperative complications of uterine repair when performed in situ or extra-abdominally following cesarean delivery.Methods
In this prospective randomized study 4925 women who underwent cesarean delivery were randomly assigned to in situ (n = 2462) or extra-abdominal (n = 2463) uterine repair (group 1 and group 2, respectively). The study compares drop in hemoglobin concentration (as a measure of intraoperative blood loss). It also compares operating time, time to return of bowel sound, and duration of hospitalization as well as rates of uterine atony, blood transfusion, intraoperative complications, additional use postoperative analgesics, endometritis, and wound infection.Results
Uterine atony developed in 96 women (3.8%) in group 1 and 226 women (9.1%) in group 2 (P = 0.001). Moreover, the operating time and the time to return of bowel sound were shorter and the rates of both additional use of postoperative analgesics and wound infection were lower in group 1 (P = 0.001, P = 0.002, P = 0.001, and P = 0.003, respectively).Conclusion
Fewer cases of uterine atony, a shorter operating time, a faster return of bowel function, a lesser need for postoperative analgesics, and lower rates of additional use of postoperative analgesics and wound infections suggest that in-situ uterine repair ought to be preferred to extra-abdominal uterine repair following cesarean delivery. 相似文献9.
This article examines data from a recent systematic evidence review on term deliveries conducted for the National Institutes of Health Consensus Conference sponsored by the Agency for Healthcare Research and Quality on vaginal birth after caesarean, from a meta-analysis of associated perinatal outcomes, and subsequent publications that meet stringent quality review standards. We present a summary of fetal and neonatal outcomes emphasizing information that clinicians and patients need to make decisions regarding mode of delivery after prior cesarean and look for areas where future studies may provide important insights. 相似文献

Objective: Women having cesarean section have a high risk of wound complications. Our objective was to determine whether high transverse skin incisions are associated with a reduced risk of cesarean wound complications in women with BMI greater than 40.Methods: A retrospective cohort study was undertaken of parturients ages 18–45 with BMI greater than 40 having high transverse skin incisions from January 2010 to April 2015 at a tertiary maternity hospital. Temporally matched controls had low transverse skin incisions along with a BMI greater than 40. The primary outcome, wound complication, was defined as any seroma, hematoma, dehiscence, or infection requiring opening and evacuating/debriding the wound. Secondary outcomes included rates of endometritis, number of hospital days, NICU admission, Apgar scores, birth weight, and gestational age at delivery. Analysis of outcomes was performed using two-sample t-test or Wilcoxon rank-sum test for continuous variables and Fisher’s exact test for categorical variables.Results: Thirty-two women had high transverse incisions and were temporally matched with 96 controls (low transverse incisions). The mean BMI was 49 for both groups. There was a trend toward reduced wound complications in those having high transverse skin incisions, but this did not reach statistical significance (15.63% versus 27.08%, p?=?.2379). Those having high transverse skin incisions had lower five minute median Apgar scores (8.0 versus 9.0, p?=?.0021), but no difference in umbilical artery pH values. The high transverse group also had increased NICU admissions (28.13% versus 5.21%, p?=?.0011), and early gestational age at delivery (36.8 versus 38.0, p?=?.0272).Conclusion: High transverse skin incisions may reduce the risk of wound complications in parturients with obesity. A study with more power should be considered. 相似文献

Objective
To calculate the prevalence of maternal obesity and to determine the relation between obesity and cesarean delivery in an urban hospital in Djibouti.Methods
In an observational cohort study, all women who had a live birth or stillbirth between October 2012 and November 2013 were considered for inclusion. Body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) was calculated throughout pregnancy, and women with a BMI of at least 30.0 were deemed to be obese. Multivariate logistic regression analyses were used to evaluate the relation between cesarean and obesity.Results
Overall, 100 (24.8%) of 404 women were obese before 14 weeks of pregnancy, as were 112 (25.2%) of 445 before 22 weeks, and 200 (43.2%) of 463 at delivery. Obesity before 22 weeks was associated with a 127% excess risk of cesarean delivery (adjusted odds ratio 2.27; 95% CI 1.07–4.82; P = 0.032). Similar trends were found when the analyses were limited to the subgroup of women without a previous cesarean delivery or primiparae.Conclusion
Prevalence of maternal obesity is high in Djibouti City and is related to an excess risk of cesarean delivery, even after controlling for a range of medical and socioeconomic variables. 相似文献12.

Objective
To determine the incidence of obstetric complications, the stillbirth rate, and the factors associated with cesarean delivery in central Nepal.Methods
A community-based prospective cohort study was undertaken in the Kaski district during 2011–2012. In total, 701 women who were at least 5 months pregnant were recruited and interviewed. Participants were followed-up and interviewed again within 45 days after delivery.Results
Of the 658 women who remained in the cohort after 43 were lost to follow-up, 12 (1.8%) had stillbirths. Cesareans accounted for 13.3% of the total deliveries. Age, urban residency, college-level education, and particularly presence of intrapartum symptoms significantly increased the likelihood of cesarean delivery. Prepartum, intrapartum, and postpartum symptoms were reported by 21.1%, 24.4%, and 10.2% of women, respectively. Common danger signs included prolonged labor, severe abdominal pain, swollen hand and body, and heavy bleeding.Conclusion
Obstetric complications and stillbirth rates were relatively high in central Nepal. Cesarean delivery appeared to meet obstetric need and was performed with medical indication, particularly after the onset of labor. 相似文献13.

ObjectiveBreech presentation is the most common form of malpresentation, and associated with perinatal asphyxia and mortality, and maternal morbidity. Data associated with labor induction in breech presentation are limited. The aim of this study was to compare maternal and fetal complication rates in induced and spontaneous vaginal, and cesarean delivery with breech presentation.Materials and MethodsPregnant women with breech presentation were grouped: spontaneous vaginal delivery (Group 1, n = 72) induced or augmented vaginal delivery (Group 2, n = 32), and cesarean delivery (Group 3, n = 253). Fetal complications were as follows: clavicle fracture, femur fracture, humerus fracture, brachial plexus injury, cephalic hematoma, pneumothorax, need for intensive care unit (ICU), and 5th minute APGAR <7. Maternal complications were as follows: vaginal hematoma, deep vaginal laceration, perineal injury (≥3rd degree), decline in hemoglobin level (>2 g/dL), and postpartum endometritis. Data were collected and analyzed retrospectively.ResultsThe highest fetal complication rate was in Group 2, and the lowest in Group 3 (p = 0.001). Clavicle fracture was significantly less in Group 3 compared with the other groups (p = 0.024). The rate of lower APGAR scores at the 5th minute was similar in all groups. Maternal complications were significantly higher in Group 2 compared with the other groups (p = 0.001). Fetal complications were 5.66-fold higher in Group 1 than in Group 3 (p = 0.002). Fetal and maternal complications were 9.48-fold and 7.48-fold higher, respectively, in Group 2 than in Group 3 (p < 0.001).ConclusionThis study is the first in literature to have investigated and analyzed neonatal complications in breech delivery according to different delivery modes including induced vaginal delivery. Due to possible complications, the risks and benefits of a specific type of delivery should be considered in breech presentation. 相似文献

Objective: To assess and compare the effectiveness and safety of single IV polus dose of carbetocin, versus IV oxytocin infusion in the prevention of PPH in obese nulliparous women undergoing emergency Cesarean Delivery.Methods: A double-blinded randomized-controlled trial was conducted on 180 pregnant women with BMI >30. Women were randomized to receive either oxytocin or carbetocin during C.S. The primary outcome measure was major primary PPH >1000?ml within 24?h of delivery as per the definition of PPH by the World Health Organization Secondary outcome measures were hemoglobin and hematocrit changes pre- and post-delivery, use of further ecobolics, uterine tone 2 and 12-h postpartum and adverse effects.Results: A significant difference in the amount of estimated blood loss or the incidence of primary postpartum haemorrhage (>1000?ml) in both groups. Haemoglobin levels before and 24-h postpartum was similar. None from the carbetocin group versus 71.5% in oxytocin group needed additional utrotonics (p?<?0.01). The uterine contractility was better in the carbetocin group at 2, and 12-h postpartum (p?<?0.05).Conclusions: A single 100-µg IV carbetocin is more effective than IV oxytocin infusion for maintaining adequate uterine tone and preventing postpartum bleeding in obese nulliparous women undergoing emergency cesarean delivery, both has similar safety profile and minor hemodynamic effect. 相似文献

OBJECTIVE: This study was undertaken to evaluate the risks and benefits of single-layer uterine closure at cesarean delivery on the index and subsequent pregnancy. STUDY DESIGN: A retrospective study of women delivered of their first live-born infants by primary low transverse cesarean delivery (1989-2001) and their subsequent pregnancy at our institution was performed. RESULTS: Of 768 women studied, 267 had single-layer and 501 had double-layer uterine closures in the index pregnancy. Single-layer closure was associated with slightly decreased blood loss (646 vs 690 mL, P<.01), operative time (46 vs 52 minutes, P<.001), endometritis (13.5% vs 25.5%, P<.001), and postoperative stay (3.5 vs 4.1 days, P<.001). In the second pregnancy, prior single-layer closure was not associated with uterine rupture after a trial of labor (0% vs 1.2%, P=.30), or other maternal or infant morbidities. Prior single-layer closure was associated with increased uterine windows (3.5% vs 0.7%, P=.046) at subsequent cesarean delivery. CONCLUSION: Single-layer uterine closure is associated with decreased infectious morbidity in the index surgery, but not uterine rupture or other adverse outcomes in the subsequent gestation. 相似文献

OBJECTIVE: This study was undertaken to assess the safety of trial of labor after previous cesarean delivery. STUDY DESIGN: Retrospective cohort study of 308,755 Canadian women with previous cesarean delivery between 1988 and 2000. Occurrences of in-hospital maternal death, uterine rupture, and other severe maternal morbidity were compared between women with a trial of labor and those with an elective cesarean section. RESULTS: Rates of uterine rupture (0.65%), transfusion (0.19%), and hysterectomy (0.10%) were significantly higher in the trial-of-labor group. Maternal in-hospital death rate, however, was lower in the trial-of-labor group (1.6 per 100,000) than in the elective cesarean section group (5.6 per 100,000). The association between trial of labor and uterine rupture was stronger in low volume (<500) than in high volume (> or =500 births per year) obstetric units. CONCLUSION: Trial of labor is associated with increased risk of uterine rupture, but elective cesarean section may increase the risk of maternal death. 相似文献
