RESUMEN

OBJECTIVES: Decreased fetal movements (DFM) is associated with adverse pregnancy outcomes. We aimed to look at the risk factors associated with DFM and outcomes of women who presented with and without DFM and outcomes before and after the implementation of a locally developed flow chart based on an evidence-based guideline. STUDY DESIGN: This was a retrospective audit of 1165 women ≥ 28 weeks' gestation with a singleton pregnancy who presented with concerns regarding DFM. We compared labor and neonatal outcomes to 4706 in a control group who did not present with concerns regarding FM. We also compared the same pregnancy outcomes before and after the implementation of hospital guidelines on the management of DFM. Statistical analyses were performed primarily using Chi square analysis and relative risk. RESULTS AND CONCLUSIONS: 1165 women presented 1645 times with DFM. Women presenting with DFM were younger, (82.8% vs 79.0%, p= <0.01 were 20 to 34-years old), tended to have a higher BMI (42.9% vs 34.4%, p=<0.001 with BMI ≥ 30) and were more likely to have mental health conditions (31.1% vs 24.2%, p=<0.01). There was no difference in the composite neonatal outcome including stillbirth, 5 min APGAR < 7 and Special Care Nursery (SCN) admission between DFM and control (22.9 vs 24.8% respectively, P = 0.18). There was no difference in perinatal outcomes pre- and post-implementation of the hospital guidelines on DFM management. Women presenting with DFM were more likely to have an induction (40.7% vs 29.9% p=<0.01) but not more likely to have a caesarean section (30.9% vs 28.8% respectively, p = 0.16). There were increasing rates of IOL with increasing number of presentations for DFM. Adoption of and adherence to locally developed guidelines was an opportunity to ensure all clinicians provide consistent advice on management and timing of birth for women presenting with DFM.

RESUMEN

STUDY QUESTION: In women with threatened miscarriage, does progesterone supplementation until the completion of the first trimester of pregnancy increase the probability of live birth? SUMMARY ANSWER: In women with threatened miscarriage, 400 mg vaginal progesterone nightly, from onset of bleeding until 12 weeks, did not increase live birth rates. WHAT IS KNOWN ALREADY: Limited evidence has indicated that vaginal micronized progesterone may make little or no difference to the live birth rate when compared with placebo in women with threatened miscarriage. Subgroup analysis of one recent randomized trial reported that in women with bleeding and at least one previous miscarriage, progesterone might be of benefit. STUDY DESIGN, SIZE, DURATION: We performed a randomized, double-blinded, placebo-controlled trial between February 2012 and April 2019. Eligible pregnant women under 10 weeks gestation, experiencing a threatened miscarriage as apparent from vaginal bleeding were randomized into two groups in a 1:1 ratio: the intervention group received 400 mg progesterone as vaginal pessaries, the control group received placebo vaginal pessaries, both until 12 weeks gestation. The primary endpoint was live birth. We planned to randomize 386 women (193 per group). The study was stopped at a planned interim analysis for futility after randomization of 278 women. PARTICIPANTS/MATERIALS, SETTING, METHODS: This trial was conducted at the Mater Mothers' Hospital, a tertiary centre for maternity care in South Brisbane, Queensland, Australia. We randomized 139 women to the intervention group and 139 women to the placebo group. Primary outcome data were available for 136 women in the intervention group and 133 women in the placebo group. MAIN RESULTS AND THE ROLE OF CHANCE: The live birth rates were 82.4% (112/136) and 84.2% (112/133) in the intervention group and placebo group, respectively (risk ratio (RR) 0.98, 95% CI 0.88 to 1.09; risk difference -0.02, 95% CI -0.11 to 0.07; P = 0.683). Among women with at least one previous miscarriage, live birth rates were 80.6% (54/67) and 84.4% (65/77) (RR 0.95, 95% CI 0.82-1.11; P = 0.550). No significant effect was seen from progesterone in women with two (RR 1.28, 95% CI 0.96-1.72; P = 0.096) or more (RR 0.79, 95% CI 0.53-1.19; P = 0.267) previous miscarriages. Preterm birth rates were 12.9% and 9.3%, respectively (RR 1.38; 95% CI 0.69 to 2.78; P = 0.361). Median birth weight was 3310 vs 3300 g (P = 0.992). There were also no other significant differences in obstetric and perinatal outcomes. LIMITATIONS, REASONS FOR CAUTION: Our study was single centre and did not reach the planned sample size because it was stopped prematurely at an interim analysis. WIDER IMPLICATIONS OF THE FINDINGS: We did not find evidence supporting the treatment effect of vaginal progesterone in women with threatened miscarriage. Progesterone in this setting should not be routinely used for threatened miscarriage. The treatment effect in women with threatened miscarriage after previous miscarriages warrants further research. STUDY FUNDING/COMPETING INTEREST(S): Mothers' and babies Golden Casket Clinical Fellowship (L.A.M.). Progesterone and placebo pessaries were provided by Perrigo Australia.B.W.J.M. reports grants from NHMRC, personal fees from ObsEva, personal fees from Merck KGaA, personal fees from Guerbet, personal fees from iGenomix, outside the submitted work.

RESUMEN

BACKGROUND: The Grobman antenatal nomogram to predict likelihood of successful vaginal birth after caesarean section (VBAC) has been validated in multiple institutions. However, due to concerns regarding inclusion of ethnicity, a new nomogram has been developed. AIM: The aim was to evaluate the efficacy of the updated Grobman nomogram without ethnicity in a regional hospital in Australia. MATERIALS AND METHODS: This was a retrospective cohort study of women electing to have a VBAC at a regional hospital over a nine-year period. Maternal demographics and obstetric outcomes were collected. Women were assigned a predicted likelihood of successful VBAC using the updated Grobman nomogram, with variables such as age, pre-pregnancy weight, height and arrest disorder as indications for previous caesarean birth, previous vaginal birth, previous VBAC and treated chronic hypertension. The predicted likelihood of successful VBAC was compared with actual successful VBAC rates. RESULTS: A total of 541 women attempted VBAC with a VBAC success rate of 74.3% (402/541). The nomogram demonstrated good fit, with a receiver operating curve area under the curve of 0.707 (95% confidence interval 0.659-0.755). Using a cut-off value of 0.5, the success rate of classification with this model was 74.3%. On comparing each predicted decile, the nomogram performed poorly in those predicted to have a <40% chance of successful VBAC. CONCLUSIONS: This study confirms the use of the updated Grobman nomogram without ethnicity, alongside usual counselling, to provide individualised advice for informed decision-making. However, clinicians should be mindful of the limitation of poor accuracy in women with a low predicted probability of VBAC.

RESUMEN

BACKGROUND: Surgical wound complications are common and occur in between 3% and 12% of obese women after cesarean delivery. An understanding of the risk factors for wound complications may inform potential areas for clinical care improvement. OBJECTIVE: This study aimed to identify the incidence and predictors of surgical wound complications in obese women after cesarean delivery. STUDY DESIGN: This was a secondary analysis of the ADding negative pRESSure to improve healING, or DRESSING, randomized controlled trial conducted at 4 maternity hospitals in Australia. A total of 2035 women with a prepregnancy body mass index ≥30 kg/m2 undergoing cesarean delivery were included. Data were collected between October 2015 and December 2019 using self-reporting of signs and symptoms, the research nurses' direct observation of the surgical site, and medical records. Independent blinded outcome assessors ascertained wound outcomes on the basis of self-reported data and medical records. Multivariable logistic regression models were used to identify independent risk factors for wound complications and surgical wound dehiscence. The 30-day cumulative incidence of wound complications and surgical wound dehiscence was calculated. RESULTS: Of the 2035 women, 317 (15.6%) developed a wound complication, whereas 211 (10.4%) developed surgical wound dehiscence. The predictors of a wound complication included 1 previous cesarean delivery (odds ratio, 1.41; 95% confidence interval, 1.05-1.90; P=.02) and ruptured membranes >12 hours (odds ratio, 1.69; 95% confidence interval, 1.08-2.66; P=.02). The odds of developing any wound complication decreased by 45% with vaginal cleansing (odds ratio, 0.55; 95% confidence interval, 0.42-0.72; P<.001) and by 59% for low transverse incision (odds ratio, 0.41; 95% confidence interval, 0.18-0.94; P=.04). The predictors of surgical wound dehiscence included 1 previous cesarean delivery (odds ratio, 1.62; 95% confidence interval, 1.14-2.31; P=.008) and ruptured membranes >12 hours (odds ratio, 1.85; 95% confidence interval, 1.10-3.12; P=.02). The odds of developing surgical wound dehiscence decreased by 50% for vaginal cleansing (odds ratio, 0.50; 95% confidence interval, 0.36-0.69; P<.001) and by 42% for using a double-layer uterine closure (odds ratio, 0.58; 95% confidence interval, 0.35-0.97; P=.04). CONCLUSION: Wound complications and surgical wound dehiscence in this population are high. The predictors observed herein would assist in identifying high-risk women. Such information may guide patient-centered decision-making in the planning of surgical births and individualized postoperative care.

RESUMEN

BACKGROUND: Surgical site infection (SSI) is the most common complication post caesarean section (CS) with a significant impact on women and health services. A bundle approach incorporating previously studied individual interventions has shown increased reductions in SSI. AIM: To assess compliance with a SSI intervention bundle and to examine readmission rates for SSI. METHODS: A retrospective audit of women who underwent CS at a regional hospital in Queensland, Australia pre-intervention (February 2015-January 2017) and post-intervention (February 2018-December 2020). RESULTS: There was good compliance with vaginal cleansing (27.7% vs 84.8%), chlorhexidine skin preparation (90.4% vs 98.4%), BMI-based antibiotic dose adjustment (48.8% vs 74.3%), and Alexis retractor use (9.9% vs 66%), pre and post-implementation periods respectively. There was a reduction in documented hair shaving (2.1% vs 0.5%). There was a trend towards less admission for SSI, a trend that could have been even better had there not been an increasing number of women with high BMI over the years. Fewer cases needed return to theatre post-implementation. Endometritis rates were unchanged. CONCLUSIONS: Good compliance can be achieved with good collaboration. There was a reduction in admission rates for SSI. Larger prospective studies are needed to further examine these findings.

RESUMEN

BACKGROUND: Surgical site infection (SSI) after a caesarean section is of concern (CS) is of concern to both clinicians and women themselves. AIMS: The aim of this study is to identify the cumulative incidence and predictors of SSI in women who are obese and give birth by elective CS. MATERIALS AND METHODS: The method used was planned secondary analysis of data from women with a pre-pregnancy body mass index (BMI) ≥30 kg/m2 giving birth by elective CS in a multicentre randomised controlled trial of a prophylactic closed-incision negative pressure wound therapy dressing. Data were collected from medical records, direct observations of the surgical site and self-reported signs and symptoms from October 2015 to December 2019. The Centers for Disease Control and Prevention definition was used to identify SSI. Women were followed up once in hospital just before discharge and then weekly for four weeks after discharge. Blinded outcome assessors determined SSI. After the cumulative incidence of SSI was calculated, multiple variable logistic regression models were used to identify independent risk factors for SSI. RESULTS: SSI incidence in 1459 women was 8.4% (122/1459). Multiple variable-adjusted odds ratios (OR) for SSI were BMI ≥40 kg/m2 (OR 1.55, 95% confidence interval (CI) 1.30-1.86) as compared to BMI 30-34.9 0 kg/m2 , ≥2 previous pregnancies (OR 1.38, 95% CI 1.00-1.80) as compared to no previous pregnancies and pre-CS vaginal cleansing (OR 0.55, 95% CI 0.33-0.99). CONCLUSIONS: Our findings may inform preoperative counselling and shared decision-making regarding planned elective CS for women with pre-pregnancy BMI ≥30 kg/m2 .

RESUMEN

OBJECTIVE: To determine the effectiveness of closed incision negative pressure wound therapy (NPWT) compared with standard dressings in preventing surgical site infection (SSI) in obese women undergoing caesarean section. DESIGN: Multicentre, pragmatic, randomised, controlled, parallel group, superiority trial. SETTING: Four Australian tertiary hospitals between October 2015 and November 2019. PARTICIPANTS: Eligible women had a pre-pregnancy body mass index of 30 or greater and gave birth by elective or semi-urgent caesarean section. INTERVENTION: 2035 consenting women were randomised before the caesarean procedure to closed incision NPWT (n=1017) or standard dressing (n=1018). Allocation was concealed until skin closure. MAIN OUTCOME MEASURES: The primary outcome was cumulative incidence of SSI. Secondary outcomes included depth of SSI (superficial, deep, or organ/body space), rates of wound complications (dehiscence, haematoma, seroma, bleeding, bruising), length of stay in hospital, and rates of dressing related adverse events. Women and clinicians were not masked, but the outcome assessors and statistician were blinded to treatment allocation. The pre-specified primary intention to treat analysis was based on a conservative assumption of no SSI for a minority of women (n=28) with missing outcome data. Post hoc sensitivity analyses included best case analysis and complete case analysis. RESULTS: In the primary intention to treat analysis, SSI occurred in 75 (7.4%) women treated with closed incision NPWT and in 99 (9.7%) women with a standard dressing (risk ratio 0.76, 95% confidence interval 0.57 to 1.01; P=0.06). Post hoc sensitivity analyses to explore the effect of missing data found the same direction of effect (closed incision NPWT reducing SSI), with statistical significance. Blistering occurred in 40/996 (4.0%) women who received closed incision NPWT and in 23/983 (2.3%) who received the standard dressing (risk ratio 1.72, 1.04 to 2.85; P=0.03). CONCLUSION: Prophylactic closed incision NPWT for obese women after caesarean section resulted in a 24% reduction in the risk of SSI (3% reduction in absolute risk) compared with standard dressings. This difference was close to statistical significance, but it likely underestimates the effectiveness of closed incision NPWT in this population. The results of the conservative primary analysis, multivariable adjusted model, and post hoc sensitivity analysis need to be considered alongside the growing body of evidence of the benefit of closed incision NPWT and given the number of obese women undergoing caesarean section globally. The decision to use closed incision NPWT must also be weighed against the increases in skin blistering and economic considerations and should be based on shared decision making with patients.

RESUMEN

BACKGROUND: Stillbirth is a major public health problem that is slow to improve in Australia. Understanding the causes of stillbirth through appropriate investigation is the cornerstone of prevention and important for parents to understand why their baby died. AIM: The aim of this study is to assess compliance with the Perinatal Society of Australia and New Zealand (PSANZ) Perinatal Mortality Clinical Practice Guidelines (2009) for stillbirths. METHODS: This is a prospective multi-centred cohort study of stillbirths at participating hospitals (2013-2018). Data were recorded into a purpose-built database. The frequency of the recommended core investigations was calculated, and χ2 test was performed for subgroup analyses by gestational age groups and timing of fetal death. A 70% compliance threshold was defined for investigations. The cause of death categories was provided according to PSANZ Perinatal Death Classification. RESULTS: Among 697 reported total stillbirths, 562 (81%) were antepartum, and 101 (15%) were intrapartum. The most common cause of death categories were 'congenital abnormality' (12.5%), 'specific perinatal conditions' (12.2%) and 'unexplained antepartum death' (29%). According to 2009 guidelines, there were no stillbirths where all recommended investigations were performed (including or excluding autopsy). A compliance of 70% was observed for comprehensive history (82%), full blood count (94%), cytomegalovirus (71%), toxoplasmosis (70%), renal function (75%), liver function (79%), external examination (86%), post-mortem examination (84%) and placental histopathology (92%). The overall autopsy rate was 52%. CONCLUSIONS: Compliance with recommended investigations for stillbirth was suboptimal, and many stillbirths remain unexplained. Education on the value of investigations for stillbirth is needed. Future studies should focus on understanding the yield and value of investigations and service delivery gaps that impact compliance.

RESUMEN

BACKGROUND: Obstetricians and gynaecologists (O&Gs) are at a risk of work-related musculoskeletal injuries (WRMI) on a daily basis. AIMS: To describe the prevalence of WRMI among O&Gs in Australia and New Zealand, explore risk factors for such injuries, and evaluate their impact. METHODS: An online survey of Fellows of Royal Australian and New Zealand College of Obstetricians and Gynaecologists was conducted in July 2016. It comprised questions on personal attributes, type of work, site and cause of WRMI, if any and treatment required. RESULTS: We received responses from 765 O&Gs giving a response rate of 38.3% (765/1997). Four hundred and ten specialists (53.6%) reported suffering a WRMI at some point, including 252 (32.9%) who reported multiple injuries. In multivariable analysis, females had increased risk of WRMI (odds ratio (OR): 2.12; 95% CI: 1.54-2.91) and among generalists and subspecialists, gynaecological oncologists had highest risk for WRMI (OR: 3.13; 95% CI: 1.21-8.14). Commonest sites of injury were back (218/633, 34.4%) and shoulder (131/633, 20.7%). Laparoscopic surgery (117/633, 18.5%) was the commonest cause of injury. Treatment was required for 88.6% of injuries (561/633) including 8.4% (53/633) of cases which required surgery. Ongoing symptoms post-injury were reported for 52.1% of injuries (330/633) and in 25.8% (163/633) of instances the practitioner needed to modify their scope of work. CONCLUSION: This survey among a large cohort of O&Gs shows a high prevalence of WRMI with a profound negative impact on the practitioner and profession. There is a pressing need to advocate for improved ergonomics in their workplaces.

RESUMEN

OBJECTIVE: Studies have noted an inconsistent risk of stillbirth in women with high BMI. There are no reports on obese women specifically selected without any pre-existing or current medical or obstetric conditions. We aimed to document the risk of stillbirth, specifically in this group of women. METHODS: A retrospective cohort study of 182,362 singleton pregnancies at gestation ≥28 weeks in Queensland, Australia between 2008 and 2016 with no pre-existing or current medical or obstetric conditions. RESULTS: We found no significant association on rates of stillbirth with increasing BMI ; odds ratios for stillbirth were 1.10, 95% CI; 0.90, 1.36 in overweight and 1.09, 95% CI; 0.87-1.37 in obese women compared to women with normal BMI. There was increasing trend in stillbirth from 37 weeks and more specifically after 40 weeks with increasing BMI. Independent of BMI, there was a statistically significant increased risk of stillbirth for women with poor antenatal care and current smokers. CONCLUSIONS: There is no firm evidence for an effect of BMI on stillbirth at ≥28 weeks gestation among women with uneventful pregnancies. Our care should focus on surveillance for early detection and monitoring of co-morbidities associated with obesity with consideration to birthing prior to 40 weeks gestation.

RESUMEN

OBJECTIVE: To evaluate a new a cut off level of fetal fibronectin as a predictor of birth in women with threatened preterm labour. DESIGN: A retrospective cohort study performed at Ipswich hospital, Ipswich, Queensland, Australia, in women with threatened preterm labour with intact membranes between 23 weeks to 34 + 6 week gestation. STUDY DESIGN: A quantitative fetal fibronectin (fFN) was performed. Maternal demographics and birth outcome data were extracted from the routinely collected perinatal data held by the hospital. The odds of preterm birth were estimated for each cut off value of fFN (10, 50 and 200 ng ml-1) using logistic regression and accounting for multiple presentations by the same woman. RESULTS: Among the 447 presentations and 376 pregnancies, rates of preterm birth <34 weeks were 2.9%, 9.2%, 3.3%, 19.6%, 4.2% and 35.3% for each category of values respectively (fFN <10, ≥10, <50, ≥50, <200 and ≥200 ng ml-1). Birth rates within 7 d of testing were 1.1%, 7.5%, 1.8%, 16.1%, 2.1% and 41.2% respectively. Comparing fFN level of <10 to a level of 10-199 ng ml-1 there was no significant increase in odds of preterm birth < 34 weeks or birth within the next 7 d (OR 2.28, 95% CI 0.84-6.17 and OR 3.61, 95% CI 0.89-14.7 respectively. CONCLUSION: In women presenting with TPL, those with levels of <200 ng ml-1 have a low risk of birthing within 7 d or before 34 weeks gestation. This allows a personalised decision making and probable discharge home without need for steroid loading.

RESUMEN

BACKGROUND: Concerns have been expressed in relation to a possible negative effect of fentanyl epidural analgesia on breastfeeding rates. A 2016 systematic review was inconclusive and suggested cohort studies be performed with control groups to allow for other potential confounding factors. AIMS: To assess the effect of fentanyl epidural analgesia in labour on breastfeeding practices. MATERIAL AND METHODS: A prospective cohort study, conducted at a metropolitan hospital, Ipswich, Queensland. Eligible women were first-time mothers, wishing to breastfeed after a vaginal birth at term. Women who had fentanyl epidural only (107) were compared with women who had subcutaneous morphine only (90), and women who had neither subcutaneous morphine nor epidural (107). RESULTS: Fewer women in the fentanyl epidural analgesia group were fully breastfeeding when leaving hospital (54.2% compared to 69.2% in the no analgesia group and 77.8% in the subcutaneous morphine group; P < 0.05). At 6 weeks postpartum, there was no evidence of difference between the groups (43% for fentanyl epidural analgesia, 52.3% for no analgesia group and 48.9% for subcutaneous morphine group; P = 0.63). Rates of induction of labour, instrumental birth and admission to special care nursery differed significantly between groups and when controlled for these, there was no association between fentanyl epidural analgesia and breastfeeding at discharge (adjusted odds ratio (OR) 0.74; 95% CI 0.39-1.41) or at 6 weeks postpartum (OR 0.75; 95% CI 0.41-1.38). CONCLUSION: Our study did not find an association between fentanyl epidural analgesia in labour and rates of fully breastfeeding at discharge and at 6 weeks postpartum.

RESUMEN

BACKGROUND: Preterm birth is associated with significant perinatal morbidity and mortality. The fetal fibronectin test (fFN) is used to manage women presenting with threatened preterm labour (TPTL). AIM: To evaluate the use of fFN in women presenting with TPTL with regard to hospital admission, tertiary hospital transfer and use of tocolytics and steroids in our hospital, against recommended guidelines. The ability of fFN <10 ng/mL, 10-49 ng/mL, 50-199 ng/mL and >200 ng/mL to predict outcome was also examined. MATERIAL AND METHODS: This was a single-centre retrospective study from January 2015 to June 2017. All women who presented to Ipswich hospital, a level two facility for births at >32 weeks of gestation, between 23 and 346  weeks of gestation with TPTL and who had fFN tests were included in the study. RESULTS: Fetal fibronectin <50 ng/mL had a negative predictive value of 93.5% (95% CI 86.5-97.1). Despite this assurance, one in four presentations resulted in hospital admission and nearly one in ten in steroids and tocolysis administration. Birth <34 weeks was 0% for fFN <10 and 2% for women with fFN levels <200 ng/mL compared to nearly 30% for levels >200 ng/mL. CONCLUSION: There is noncompliance with use of fFN to its full potential. This small study also provides support for the use of a 200 ng/mL cut-off fFN level for birth <34 weeks. This would avoid the need to transfer to a tertiary facility many women who present with TPTL.

RESUMEN

BACKGROUND: Pre-labour rupture of membranes (PROM) at term is a common event with early induction of labour reducing infectious morbidity without increasing the caesarean rate. Syntocinon is commonly used for induction but prostaglandins are also routinely used. Large studies have shown no difference in the maternal and neonatal outcomes with either method. AIM: To assess the safety and efficacy of vaginal prostaglandin (PG) compared to syntocinon for induction of labour in term-PROM. METHOD: This was a single-centre randomised controlled trial at Ipswich Hospital of women presenting at ≥37 weeks gestation with PROM. Women were randomised and managed in labour as per local guidelines. Analysis was by intention to treat. RESULTS: One hundred and eighty-four women were recruited, 90 in the PG group and 94 in the oxytocin group. Women in both arms were of similar demographics and 53% of women in the PG group did not require any oxytocin. There was a statistically significant lower incidence of fetal heart rate abnormality in the PG group, 4.4% versus 12.8%. There was no difference in epidural use, caesarean section, maternal infection, admission to special care nursery or neonatal sepsis. Time to onset of labour was significantly longer in the PG group, 25.7 h versus 19.7 h but with no difference in the length of first stage. Maternal satisfaction was high in both groups with no significant difference in breastfeeding rates. CONCLUSION: Induction of labour with oxytocin or vaginal prostaglandins are safe and efficacious options for women in the context of PROM at term.

RESUMEN

The National Health and Medical Research Council (NHMRC) Centre of Research Excellence in Stillbirth and the Perinatal Society of Australia and New Zealand (PSANZ) have recently partnered in updating an important clinical practice guideline, Care of pregnant women with decreased fetal movements. This guideline offers 12 recommendations and a suggested care pathway, with the aim to improve the quality of care for women reporting decreased fetal movements through an evidence-based approach. Adoption of the guideline by clinicians and maternity hospitals could result in earlier identification of higher-risk pregnancies, improved perinatal health outcomes for women and their babies, and reduced stillbirth rates.

RESUMEN

OBJECTIVE: To evaluate the percentage change in total ßeta-unit human chorionic gonadotropin (ßhCG) levels (%ΔßhCG) in the prediction of treatment outcomes following intravaginal misoprostol for missed miscarriage before 13 weeks. METHODS: A secondary analysis of a randomised controlled study of medical management of miscarriage was performed. Total ßhCG levels were collected before misoprostol (baseline) and after a planned seven day interval (follow-up), when a transvaginal ultrasound (TVUS) reported a gestational sac as present or not. If no sac at TVUS, surgery was indicated on clinical criteria. %ΔßhCG ((baseline ßhCG - follow-up ßhCG)/baseline ßhCG × 100) was evaluated in the prediction of a sac at TVUS and surgery on clinical criteria. RESULTS: %ΔßhCG was calculated for cases with ßhCG levels within two days of misoprostol and TVUS; calculation interval determined case number. The median %ΔßhCG for 24 cases with a persistent sac (6-9 day interval) was significantly lower than for 145 with no sac (58.75% (interquartile range (IQR): 37.59-76.69; maximum 86.54) vs 97.65% (IQR: 95.44-98.43); P < 0.0001). The median %ΔßhCG for eight cases needing surgery on clinical criteria (5-9 day interval) was significantly lower than for 140 cases with no sac not needing surgery (79.68% (IQR: 64.63-91.15; maximum 94.06) vs 97.68% (IQR: 95.61-98.50); P < 0.0001). The area under the receiver-operator curve was 0.975 for prediction of a persistent sac and 0.944 for prediction of surgery on clinical criteria, respectively. %ΔßhCG > 87% predicted no sac at TVUS. %ΔßhCG > 94.5% predicted no surgery on clinical criteria. CONCLUSION: %ΔßhCG calculation over one week reliably predicted treatment outcomes after medical management of missed miscarriage.

RESUMEN

Caesarean section (CS) rates have been increasing worldwide and have caused concerns. For meaningful comparisons to be made World Health Organization recommends the use of the Ten-Group Robson classification as the global standard for assessing CS rates. 2625 women who birthed over a 12-month period were analysed using this classification. Women with previous CS (group 5) comprised 10.9% of the overall 23.5% CS rate. Women with one previous CS who did not attempt VBAC contributed 5.3% of the overall 23.5% CS rate. Second largest contributor was singleton nulliparous women with cephalic presentation at term (5.1% of the total 23.5%). Induction of labour was associated with higher CS rate (groups 1 and 3) (24.5% versus 11.9% and 6.2% versus 2.6%, resp.). For postdates IOL we recommend a gatekeeper booking system to minimise these being performed <41 weeks. We suggest setting up dedicated VBAC clinic to support for women with one previous CS. Furthermore review of definition of failure to progress in labour not only may lower CS rates in groups 1 and 2a but also would reduce the size of group 5 in the future.

RESUMEN

BACKGROUND: First-trimester care of maternal thyroid dysfunction has previously been shown to be poor. This study evaluates early management of thyroid dysfunction in pregnancy in Australia. METHODS: Patients reviewed by the Obstetric Medicine team for thyroid dysfunction from 1 January 2012 to 30 June 2013 were included. Data were collected on gestation at referral from the patient's general practitioner to the antenatal clinic, information provided in the referral letter, thyroid function tests and thyroid medications. RESULTS: Eighty-five women were included in the study. At the time of general practitioner referral to antenatal services, 19% of women with preexisting thyroid disease had no thyroid function tested. Forty-three percent had an abnormal thyroid-stimulating hormone defined as being outside the laboratory-specific pregnancy reference range if available, or outside the level of 0.1-2.5 mIu/L in the first trimester, 0.2-3.0 mIu/L in the second trimester and 0.3-3.0 mIu/L in the third trimester. Only 21% of women increased their thyroxine dose prior to their first antenatal clinic review. CONCLUSION: This study highlights that a significant proportion of women with known thyroid disease either have untested thyroid function in the first trimester or a thyroid-stimulating hormone outside of levels recommended by guidelines.

RESUMEN

BACKGROUND: Pain after hysteroscopy is usually minimal but some women need additional analgesia while in the recovery ward and some require overnight hospital admission to control pain. Intrauterine installation of an anaesthetic after hysteroscopy may reduce pain. AIMS: To see if intrauterine levobupivacaine reduces post-procedure pain, need for analgesia and allow earlier return to normal activity. MATERIALS AND METHODS: This was a double-blind randomised controlled trial. Women having hysteroscopy under general anaesthesia were allocated to receive intrauterine instillation of levubupivacaine or normal saline at the end of the procedure. Women were assessed in the recovery ward by a verbal descriptor pain scale and need for additional analgesia and followed up on day 3 to further assess pain and return to normal activity. RESULTS: There were no significant differences in demographic characteristics or indication for surgery between the 224 women in the study group or the 214 women in the control group. At two hours post-procedure, 156/224 (70%) study women versus 119/214 (56%) control women had no pain; (relative risk (RR) 0.68 and 95% confidence interval (CI) 0.53-0.87). There were 182/224 (81%) study women versus 154/214 (72%) control women with a pain score < 5 (RR 0.67; 95% CI 0.47-0.95). Fewer women in the study group required additional analgesia 54/224 (24%) versus 88/214 (41%) (RR 0.58; 95% CI 0.44-0.78). There was no significant difference between groups with regards to pain at 24 h post-procedure or return to activity. CONCLUSION: Intrauterine instillation of levobupivacaine reduced post-procedure pain and need for additional pain relief.
