Impact of 'decision-to-delivery' interval on maternal and perinatal outcomes: a retrospective study of emergency caesarean section from 2017 to 2021 at a secondary health facility in Nigeria.

BACKGROUND: The decision-to-delivery interval (DDI) for a caesarean section is among the factors that reflect the quality of care a pregnant woman receives and the impact on maternal and foetal outcomes and should not exceed 30 min especially for Category 1 National Institute for Health and Care Excellence (NICE) guidelines. Herein, we evaluated the effect of decision-to-delivery interval on the maternal and perinatal outcomes among emergency caesarean deliveries at a secondary health facility in north-central Nigeria. METHODS: We conducted a four-year retrospective descriptive analysis of all emergency caesarean sections at a secondary health facility in north-central Nigeria. We included pregnant mothers who had emergency caesarean delivery at the study site from February 10, 2017, to February 9, 2021. RESULTS: Out of 582 who underwent an emergency caesarean section, 550 (94.5%) had a delayed decision-to-delivery interval. The factors associated with delayed decision-to-delivery interval included educational levels (both parents), maternal occupation, and booking status. The delayed decision-to-delivery interval was associated with an increase in perinatal deaths with an odds ratio (OR) of 6.9 (95% CI, 3.166 to 15.040), and increased odds of Special Care Baby Unit (SCBU) admissions (OR 9.8, 95% CI 2.417 to 39.333). Among the maternal outcomes, delayed decision-to-delivery interval was associated with increased odds of sepsis (OR 4.2, 95% CI 1.960 to 8.933), hypotension (OR 3.8, 95% 1.626 TO 9.035), and cardiac arrest (OR 19.5, 95% CI 4.634 to 82.059). CONCLUSION: This study shows a very low optimum DDI, which was associated with educational levels, maternal occupation, and booking status. The delayed DDI increased the odds of perinatal deaths, SCBU admission, and maternal-related complications.

Parasitic pygopagus conjoined twins' incidental findings in the obstructed labor of an intrapartum dead baby that had undergone emergency C-section: rare case report in South Papua.

BACKGROUND: Conjoined twins (CT), which used to be historically defined as "monstrous human" and previously so-called Siamese twins in the early eighteenth century, are one of the very rare congenital malformations with an uncertain etiology and complex yet remain inconclusively debatable regarding its pathophysiological mechanisms of fusion and fission theories. Among all types of CT, parasitic CT, especially the pygopagus sub-type, is exceedingly rarer. To the best of the authors' knowledge, no parasitic CT had been reported in Papua, and this is the first finding in South Papua. CASE REPORT: Herein, a 30-year-old multigravida female with 37th-week gestation, previous twice spontaneous miscarriage, and non-adequate antenatal care history is presented with a chief complaint of painful construction and greenish fluid leakage from the vagina, with an examination that showed a cephalic presentation with a "peculiar" big mass at the upper uterus and complete cervical dilation toward second-stage inpartu. Vaginal delivery was performed with a complication of obstructed labor due to uncommon dystocia with a suspected "big mass" below the fetal buttocks and intrapartum dead. Intrapartum transabdominal ultrasound demonstrates a gross anatomically like an organ inside a fluid-filled mass with unidentified parts, leading to a suspected type of congenital malformation at the baby's sacral region. Emergency C-section was done with findings of parasitic pygopagus CT, showing an attachment of a large irregular fluid-filled mass-like incomplete twin (parasite) with palpable soft tissue and bony structure inside to the buttocks of a male autosite twin, and an additional third leg which happened to be an under-developed lower extremity with a sacrum-like structure. CONCLUSIONS: An obstetrician's routine ANC and critical radiological evaluation will increase the odds of identifying CT or other congenital malformations to provide better delivery planning or further management. Increasing maternal health knowledge in society, improving medical skills and knowledge levels for health providers, and advancing supporting facilities and specialists are future strategies for managing and preventing such cases in low-middle-income countries.

Retrospective review of surgeon administered transversus abdominis plane blocks at emergency caesarean.

BACKGROUND: Effective analgesics with minimal side effects are imperative for patient and neonate wellbeing postpartum. Post-caesarean section ultrasound-guided transversus abdominis plane (TAP) blocks have proven safety and efficacy. Surgical TAP blocks appear effective and require little time and equipment. No previous examination of surgical TAP blocks in patients having undergone emergency caesarean section has been undertaken. AIMS: To investigate surgical TAP block and multimodal analgesic use during emergency caesarean section, the effect on surgical time, post-operative analgesia use, and admission length. MATERIALS AND METHODS: We performed a retrospective review of 250 patients who underwent emergency caesarean in 2022. Surgical TAP blocks were performed with 20 mL of 0.375% ropivacaine either side. Primary outcomes included surgical time, length of admission, time to first request of rescue opiate, opiate use in first post-operative 24 h, total dose used during admission, and opiates prescribed on discharge. RESULTS: Ninety-six patients received surgical TAP blocks, and 154 did not. There were no statistically significant differences in the primary outcomes. Subgroup analyses were performed in patients who did not receive intrathecal morphine, body mass index over 30 kg/m2, for patients whom this was their first caesarean, and for TAP blocks versus local infiltration to the wound. There were no significant differences in the primary outcomes in these subgroups. CONCLUSIONS: Surgical TAP blocks did not prolong surgical time or decrease post-operative analgesia use or admission length in patients having undergone emergency caesarean. Patient-tailored multimodal analgesia is encouraged, although more research is needed.

The development of a prediction model for arrest of labour to be used at regular check-ups, during 36 or 37 gestational weeks, for primiparas: a retrospective cohort study.

PURPOSE: An emergency caesarean section (CS) has more complications than a planned CS. The arrest of labour is a major indication for an emergency CS. This study aimed to develop a prediction model for the arrest of labour to be used in regular check-ups at 36 or 37 gestational weeks for primiparas. METHODS: This was a retrospective cohort study conducted at a single institution in Japan using data from January 2007 to December 2013. Primiparas attending regular check-ups during 36 or 37 gestational weeks, with live single foetuses in a cephalic presentation were included. The outcome was the incidence of labour arrest. Candidate predictors included 25 maternal and foetal findings. We developed a prediction model using logistic regression analysis with stepwise selection. A score was assigned to each predictor of the final model based on their respective ß coefficients. RESULTS: A total of 739 women were included in the analysis. Arrest of labour was diagnosed in 47 women (6.4%), and all of them delivered by emergency CS. The predictors in the final model were a Bishop score ≤ 1, maternal height ≤ 154 cm, foetal biparietal diameter ≥ 91 mm, pre-pregnancy weight ≥ 54 kg, maternal haemoglobin concentration ≥ 11.0 g/dl, and amniotic fluid index ≥ 13. The area under the receiver operating characteristic curve was 0.783. CONCLUSION: We have developed the first model to predict arrested labour before its onset. Although this model requires validation using external samples, it will help clinicians and pregnant women to control gestational conditions and make decisions regarding planned CS.

Effect of in situ simulation training for emergency caesarean section on maternal and infant outcomes.

BACKGROUND: Emergency caesarean section (ECS) is an effective method for rapid termination of pregnancy and for saving maternal and foetal life in emergencies. Experts recommend that the interval from decision of operation to the decision to delivery interval (DDI) should be shortened as much as possible. Studies have shown that improving communication skills among staff by performing simulation drills shortens DDI, thus reducing the occurrence of adverse obstetric events and protecting maternal and child safety. In situ simulation (ISS) training is a simulation-based training approach for clinical team members conducted in a real-world clinical setting. In August 2020, Anhui Maternal and Child Health Hospital began ISS training on the rapid obstetric response team (RRT) in our hospital area for emergency caesarean section. This study aimed to investigate the effect of implementing in situ simulation training for emergency caesarean section on maternal and child outcomes by comparing maternal and child-related data on emergency caesarean section in two hospital areas. METHODS: Data on cases of emergency caesarean delivery implemented in two hospital districts from August 2020 to August 2022 were collected: 19 in the untrained group and 26 in the training group. The two groups were compared concerning the interval from the decision of operation to the decision to delivery interval (DDI), the interval from the decision of operation to the initiation of skin incision, the interval from skin incision to the decision to delivery interval, and the neonatal situation. RESULTS: Primary outcome comparison: The training group had a significantly shorter interval between the DDI compared to the untrained group (8.14 ± 3.13 vs. 11.03 ± 3.52, P = 0.006). Secondary outcomes comparison: The training group had a significantly shorter interval between the decision to cut skin compared to the untrained group (6.45 ± 2.21 vs. 9.95 ± 4.02, P = 0.001). However, there was no significant difference in the interval between cutting skin and infant delivery between the two groups (2.24 ± 0.08 vs. 2.18 ± 0.13, P > 0.05). Additionally, the Apgar score at 1 min after birth was higher in the training group compared to the untrained group (7.29 ± 2.38 vs. 6.04 ± 1.46, P < 0.05). CONCLUSIONS: The DDI for emergency caesarean section procedures can be significantly shortened, and neonatal Apgar scores at 1 min improved by implementing in situ simulation training for emergency caesarean section in obstetric rapid response teams. In situ simulation training is an effective tool for training in emergency caesarean section procedures and is worth promoting.

Timing of emergency caesareans - what's the rush? A retrospective multi-centred observational study into decision-to-delivery interval and maternal and fetal outcomes.

This study primarily aims to investigate the relationship between decision-to-delivery interval (DDI) and fetal and maternal outcomes in patients undergoing an emergency caesarean section. A secondary aim was to investigate if any maternal or labour features adversely affected outcomes. Two-hundred and forty-six patients underwent an emergency caesarean section within a 9 month period. Outcomes considered included estimated blood loss, need for special care baby unit admission, need for neonatal resus in the form of continuous positive airway pressure and initial APGARs. A multivariate regression analysis was used. This study found no relation between DDI and outcomes.

Emergencies in obstetric anaesthesia: a narrative review.

We conducted a narrative review in six areas of obstetric emergencies: category-1 caesarean section; difficult and failed airway; massive obstetric haemorrhage; hypertensive crisis; emergencies related to neuraxial anaesthesia; and maternal cardiac arrest. These areas represent significant research published within the last five years, with emphasis on large multicentre randomised trials, national or international practice guidelines and recommendations from major professional societies. Key topics discussed: prevention and management of failed neuraxial technique; role of high-flow nasal oxygenation and choice of neuromuscular drug in obstetric patients; prevention of accidental awareness during general anaesthesia; management of the difficult and failed obstetric airway; current perspectives on the use of tranexamic acid, fibrinogen concentrate and cell salvage; guidance on neuraxial placement in a thrombocytopenic obstetric patient; management of neuraxial drug errors, local anaesthetic systemic toxicity and unusually prolonged neuraxial block regression; and extracorporeal membrane oxygenation use in maternal cardiac arrest.

Heat stable carbetocin vs. oxytocin for the prevention of post-partum hemorrhage in emergency caesarean delivery: a randomized controlled trial.

OBJECTIVES: To evaluate the uterotonic effect of carbetocin compared with oxytocin in emergency cesarean delivery in Iraq. METHODS: A double-blinded randomized noninferiority single center trial. Three-hundred patients were systematically randomized to intravenous bolus injection of 10 IU oxytocin or 100 mcg carbetocin after delivery in a ratio of 2:1. The primary outcome was additional uterotonic use when inadequate uterine tone occur in the first 24 h after delivery. Secondary outcomes include the need for blood transfusion, blood pressure and pulse rate changes within an hour of drugs administration. Noninferiority margins for the relative risks outcomes was 4%. RESULTS: Addition uterotonics use was significantly lower in carbetocin group with a risk ratio of 0.36. Carbetocin was superior to oxytocin in reducing the need for additional uterotonic drugs by 12% and non-inferior to oxytocin for blood transfusion 3.5%. Noninferiority was not shown for the outcome of sever blood loss. Miner changes in blood pressure and pulse rate were observed in carbetocin group compared to oxytocin but clinically were not significant. CONCLUSIONS: Heat stable carbetocin is effective in reducing additional uterotonics use compared to oxytocin without clinically significant change in blood pressure or pulse rate, therefore, can be a potential alternative in Iraq.

Risk factors associated with unplanned caesarean section in women with placenta previa: a cohort study.

Unplanned/emergency caesarean section (CS) can lead to an increased risk of increased risk of adverse maternal and perinatal outcomes. This prospective observational study was conducted in a tertiary centre in South India to determine the factors associated with increased risk of unplanned/emergency CS among women with placenta previa (PP). Primary outcome was the unplanned CS defined as emergency CS performed, prior to the scheduled date of delivery, for profuse vaginal bleeding or onset of labour pains. Obstetric morbidity and maternal-foetal outcomes were also compared between major and minor degree of PP. Major degree PP (OR 3.56; 95% CI: 1.73-7.32), first episode of bleeding at less than 29 weeks of gestation (OR 6.25; 95% CI: 2.14-18.24), and the haemoglobin level at admission (OR: 0.72; 95% CI: 0.57-0.91) were found to be associated with higher odd for undergoing unplanned CS. Identifying these women at high risk of unplanned CS, especially in limited resource setting, helps for a timely and early referral to tertiary centres with expertise to manage complications along with facilities for blood transfusion and interventional radiology can help to optimise maternal and perinatal outcomes.Impact StatementWhat is already known on this subject? With increasing numbers of caesarean sections (CSs) and assisted reproductive techniques, the rate of PP is constantly on the rise. Unplanned CS is associated with increased risk of adverse maternal and perinatal complications.What do the results of this study add? Nearly, 40% among those who underwent CS were unplanned. Major degree placenta previa (PP) (OR 3.56; 95% CI: 1.73-7.32), first episode of bleeding at less than 29 weeks of gestation (OR 6.25; 95% CI: 2.14-18.24), and the haemoglobin level at admission (OR: 0.72; 95% CI: 0.57-0.91) were found to be associated with higher odd for undergoing unplanned CS.What are the implications of these findings for clinical practice and/or further research? Identifying women with PP at high risk of unplanned CS, especially in limited resource setting, helps for a timely and early referral to tertiary centres with expertise to manage complications, facilities for blood transfusion and interventional radiology, which optimise maternal and perinatal outcomes.

Decision-to-delivery interval and neonatal outcomes for category-1 caesarean sections during the COVID-19 pandemic.

General anaesthesia is known to achieve the shortest decision-to-delivery interval for category-1 caesarean section. We investigated whether the COVID-19 pandemic affected the decision-to delivery interval and influenced neonatal outcomes in patients who underwent category-1 caesarean section. Records of 562 patients who underwent emergency caesarean section between 1 April 2019 and 1 July 2019 in seven UK hospitals (pre-COVID-19 group) were compared with 577 emergency caesarean sections performed during the same period during the COVID-19 pandemic (1 April 2020-1 July 2020) (post-COVID-19 group). Primary outcome measures were: decision-to-delivery interval; number of caesarean sections achieving decision-to-delivery interval < 30 min; and a composite of adverse neonatal outcomes (Apgar 5-min score < 7, umbilical arterial pH < 7.10, neonatal intensive care unit admission and stillbirth). The use of general anaesthesia decreased significantly between the pre- and post-COVID-19 groups (risk ratio 0.48 (95%CI 0.37-0.62); p < 0.0001). Compared with the pre-COVID-19 group, the post-COVID-19 group had an increase in median (IQR [range]) decision-to-delivery interval (26 (18-32 [4-124]) min vs. 27 (20-33 [3-102]) min; p = 0.043) and a decrease in the number of caesarean sections meeting the decision-to-delivery interval target of < 30 min (374/562 (66.5%) vs. 349/577 (60.5%); p = 0.02). The incidence of adverse neonatal outcomes was similar in the pre- and post-COVID-19 groups (140/568 (24.6%) vs. 140/583 (24.0%), respectively; p = 0.85). The small increase in decision-to-delivery interval observed during the COVID-19 pandemic did not adversely affect neonatal outcomes.

Three kinds of caesarean sections: the foetal/neonatal perspective.

In the age of hospital births, it is commonplace to contrast the vaginal route and the abdominal route as the basic classification. From the "point of view" of the foetus/neonate, we provide reasons to contrast "birth without labour" (that is birth by pre-labour caesarean section) and all the other vaginal and abdominal modes of birth. From a great diversity of theoretical reasons, one can anticipate that babies born by pre-labour caesarean sections are different from the others. We also provide reasons to popularize the concepts of "in labour non-emergency caesarean sections" and "planned in-labour caesarean sections".

Determinants and effects of fluid status changes in caesarean delivered neonates.

AIM: Evidence suggests that caesarean section is associated with a reduced placental transfusion and poor iron-related haematological indices, both in cord and peripheral blood, compared with vaginal delivery. We assessed determinants and effects of fluid status changes on placental transfusion in neonates delivered by elective (ElCD) and emergency (EmCD) caesarean section. METHODS: Placental transfusion was estimated by ∆ haematocrit (Hct) increase from birth to 48 hours of life, accounting for contemporaneous ∆ body weight decrease, in 143 women/infant pairs, 62 who underwent ElCD and 81 EmCD, respectively. RESULTS: Cord blood Hct levels at birth of ElCS neonates were significantly lower than those of EmCD neonates (44.58 + 4.87vs 49.93 + 4.29, P = .01). At 48 hours of life, capillary heel Hct levels of ElCD and of EmCD neonates were comparable. ElCD had a higher ∆ body weight decrease (ElCD -7.25 ± 1.74% vs EmCD -6.31 ± 2.34% [P: .011]) and ∆ Hct increase ([ElCD + 5.93 ± 4.92 vs EmCD + 3.59 ± 5.29, [P: .011]). In a linear regression model analysis, gestational age in ElCD neonates had a significant effect on the differences in arterial cord blood Hct, body weight at birth and body weight decrease at 48 hours after birth. CONCLUSION: Early-term surgical delivery is a determinant of transient dilutional anaemia in ElCD neonates, lacking neuroendocrine response of labour and delivery.

Transfer of an interprofessional emergency caesarean section training program: using questionnaire combined with outcome data of newborn.

PUPROSE: An emergency caesarean section is a potentially life-threatening situation both for the mother and the newborn. Non-technical skills can be improved by simulation training and are necessary to manage this urgent situation successfully. The objective of this study was to investigate, if training of emergency caesarean section can be transferred into daily work to improve the outcome parameters pH an APGAR of the newborn. METHODS: In this pre-post study, 141 professionals took part in a training for emergency caesarean section. Participants received a questionnaire, based on the tools "Training Evaluation Inventory" and "Transfer Climate Questionnaire" 1 year after training. Outcome data of the newborn were collected from the hospitals information system. RESULTS: Except the scale "extinction", Cronbach's alpha was higher than 0.62. All scales were rated lower than 2.02 on a 5-point Likert Scale (1 = fullest approval; 5 = complete rejection). "Negative reinforcement" was rated with 2.87 (SD 0.73). There were no significant differences in outcome data prior. The questionnaire fulfils criteria for application except the scale "extinction". CONCLUSION: The presented training course was perceived as useful by the professionals and attitudes toward training were positive; the content was positively reinforced in practice 1 year after training. Parameters of the newborn did not change. It is conceivable that other outcome parameters (e.g. posttraumatic stress disorder) are addressed by the training. The development of relevant outcome parameters for the quality of emergency sections needs further investigation.

Comparison of maternal and perinatal morbidity between elective and emergency caesarean section in singleton-term breech presentation.

The objective of the study was to compare maternal and neonatal adverse outcomes between elective caesarean section (ElCS) and emergency caesarean section (EmCS) for singleton-term breech presentation. This study included women with singleton breech presentation who underwent ElCS or EmCS at term during 2007-2015 at Siriraj Hospital (Thailand). Complete data were collected for 2178 pregnant women. Of those, 1322 (60.7%) women underwent EmCS, and 856 (39.3%) delivered by ElCS. Maternal and perinatal morbidity were compared. There was no maternal or perinatal death in either group. Maternal morbidity was comparable between groups, except for longer hospital stay in the EmCS group (p = .047). One-minute Apgar score was significantly lower in the EmCS group (p = .040). There was no significant difference in 5-min Apgar score between groups. No significant difference was observed for serious maternal and neonatal morbidity between women who underwent ElCS versus those who underwent EmCS for singleton-term breech presentation.IMPACT STATEMENTWhat is already known on this subject? Emergency caesarean section (EmCS) is generally known to be associated with a higher risk of maternal and neonatal complications than elective caesarean section (ElCS).What do the results of this study add? In singleton-term breech presentation, EmCS in tertiary care setting was not associated with an increase in serious maternal and neonatal morbidity compared with EICS. Cord prolapse as an indication for emergency caesarean section was significantly associated with adverse outcomes while advanced cervical dilation ≥7 cm or low foetal station ≥+1 did not have an impact on maternal and neonatal complications.What are the implications of these findings for clinical practice and/or further research? Mean gestational age in both the ElCS and EmCS groups was approximately 38 weeks and 5 d; there were no neonatal cases with respiratory distress syndrome. Our findings suggest further prospective study in planned caesarean section scheduled for 38-39 weeks in patients with term breech presentation. The results of such a study could yield lower rates of both EmCS and potential adverse outcomes.

Women's psychosocial outcomes following an emergency caesarean section: A systematic literature review.

BACKGROUND: Given the sudden and unexpected nature of an emergency caesarean section (EmCS) coupled with an increased risk of psychological distress, it is particularly important to understand the psychosocial outcomes for women. The aim of this systematic literature review was to identify, collate and examine the evidence surrounding women's psychosocial outcomes of EmCS worldwide. METHODS: The electronic databases of EMBASE, PubMed, Scopus, and PsycINFO were searched between November 2017 and March 2018. To ensure articles were reflective of original and recently published research, the search criteria included peer-reviewed research articles published within the last 20 years (1998 to 2018). All study designs were included if they incorporated an examination of women's psychosocial outcomes after EmCS. Due to inherent heterogeneity of study data, extraction and synthesis of both qualitative and quantitative data pertaining to key psychosocial outcomes were organised into coherent themes and analysis was attempted. RESULTS: In total 17,189 articles were identified. Of these, 208 full text articles were assessed for eligibility. One hundred forty-nine articles were further excluded, resulting in the inclusion of 66 articles in the current systematic literature review. While meta-analyses were not possible due to the nature of the heterogeneity, key psychosocial outcomes identified that were negatively impacted by EmCS included post-traumatic stress, health-related quality of life, experiences, infant-feeding, satisfaction, and self-esteem. Post-traumatic stress was one of the most commonly examined psychosocial outcomes, with a strong consensus that EmCS contributes to both symptoms and diagnosis. CONCLUSIONS: EmCS was found to negatively impact several psychosocial outcomes for women in particular post-traumatic stress. While investment in technologies and clinical practice to minimise the number of EmCSs is crucial, further investigations are needed to develop effective strategies to prepare and support women who experience this type of birth.

Comparison of neonatal outcomes between category-1 and non-category-1 Primary Emergency Cesarean Section: A retrospective record review in a tertiary care hospital.

OBJECTIVE: To compare neonatal outcomes between Category-1 and Non-Category-1 Primary Emergency Cesarean Section. METHODS: This was a retrospective analysis, conducted at Aga Khan University Hospital Karachi from January 1st 2016 till December 31st 2016. Non-probability purposive sampling technique was used. A sample size of 375 patients who had primary Emergency Caesarean Section (Em-CS) was identified by keeping CS rate of 41.5% and 5% bond on error. Data was collected from labor ward, operating theatre and neonatal ward records by using structured questionnaire. RESULTS: In the current study, out of 375 participants who underwent primary Em-CS; majority (89.3%) were booked cases. Two-hundred-eighty-two (75.2%) were primiparous women. Two hundred and thirty (61.3%) were at term and 145(38.7%) were preterm. The main indication among Category-1 CS was fetal distress (15.7%). For Non-Category-1 CS, non-progress of labour (45.1%) was the leading cause of abdominal delivery. Except for APGAR score at one minute (p value = 0.048), no other variables were statistically significant when neonatal outcomes were compared among Category-1 and Non-Category-1 CS. CONCLUSION: In this study, fetal distress and non-progress of labor were the main indications for Category-1 and Non-Category-1 CS respectively. We did not find statistically significant association between indications of Em CS and neonatal outcomes. However further prospective studies are required to confirm this association.

The decision delivery interval in emergency caesarean section and its associated maternal and fetal outcomes at a referral hospital in northern Tanzania: a cross-sectional study.

BACKGROUND: Decision delivery interval (DDI) is the time line between a decision to conduct an emergency caesarean section and actual delivery of the baby. Prolong DDI constitute a third phase delay in provision of emergency obstetric care. Intervention designed to minimize DDI are vital, in attempt to prevent maternal morbidity and neonatal morbidity and mortality. The feasibility and practicability of the recommended DDI in recent studies have been questioned especially in limited resource setting and therefore the objective of our study was to determine the DDI and its associated fetalmaternal outcomes at a tertiary referral hospital in Tanzania. METHODS: This was a retrospectivecross-sectional study of inpatient cases who underwent emergency caesarean section from January to September 2014. Data were collected from birth registry and case files of patients. Data analysis was performed using statistical package for social science (SPSS) version 22.0. Odds ratio (ORs) and 95% confidence interval for maternal and fetal outcomes associated with DDI were estimated using Logistic regression models. A p-value of less than 5% was considered statistically significant. RESULTS: A total of 598 women who underwent emergency caesarean section were recruited. The median Decision Delivery Interval was 60 min [IQR 40-120]. Only 12% were operated within 30 min from decision time. Shortest DDI was seen in patients with Cephalopelvic Disproportion (CPD) and uterine rupture (40 min and 45.5 min) as compared to other conditions. Cases with impending uterine rupture, cord prolapse, APH and fetal distress showed to have shorter DDI. There was no significant association between DDI and neonatal transfer,1st and 5thminute Apgar score, maternal blood loss (OR: 5.79; 95% CI 0.63-1.64) and hospital stay (OR: 1.02; 95% 0.63-1.64). CONCLUSIONS: Contrary to the recommended DDI by ACOG & AAP of 30 min is not feasible in our setting, time frame of 75 min could be acceptable but clinical judgment is required to assess on the urgency of caesarean section in order to prevent maternal and neonatal morbidity and mortality.

Risk factors for emergency caesarean section in planned vaginal breech delivery.

PURPOSE: To identify risk factors for emergency caesarean section in women attempting a vaginal breech delivery at term. METHODS: Data from 1092 breech deliveries performed between 1998 and 2013 at a Swiss cantonal hospital were extracted from an electronic database. Of the 866 women with a singleton, full term pregnancy, 464 planned a vaginal breech delivery. Fifty-seven percent (265/464) were successful in delivering vaginally. Multivariate regression analyses of risk factors were performed, and neonatal and maternal complications were compared. RESULTS: Risk factors for failed vaginal delivery were peridural anaesthesia (OR 2.05; 95 % CI 1.09-3.84; p = 0.025), nulliparity (OR 2.82; 95 % CI 1.87-4.25; p < 0.001), high birth weight (OR 1.17; 95 % CI 1.04-1.30; p = 0.006) and induction of labour (OR 1.56; 95 % CI 1.003-2.44; p = 0.048). Maternal age, height and weight; gestational age; or newborn length and head circumference were not associated with an unplanned caesarean section. The rate of successful vaginal delivery in the low risk sub-group (multiparous women without induction of labour) was 58-83 %, depending on birth weight category. The likelihood of success for the high risk sub-group (nulliparous women with induction of labour) fell below a third at neonatal birth weights >3250 g. Complication rates were low in the cohort. CONCLUSIONS: Use of peridural anaesthesia, nulliparity, high birth weight and induction of labour were risk factors for unsuccessful vaginal breech delivery requiring an unplanned caesarean section. Awareness of these risk factors is useful when counselling women who are considering a vaginal breech delivery.

Assessment of a vaginal device for delivery of the impacted foetal head at caesarean section.

The aim of this study was to assess a new device (Tydeman Tube) designed to facilitate delivery of the impacted foetal head at caesarean section. Standard digital vaginal technique and the Tydeman Tube were each used to elevate the foetal head on a validated full dilatation caesarean simulator. Greater elevation of the foetal head was achieved with the Tydeman Tube than digital technique (mean difference +9.1 mm, p < 0.001). Although greater force was applied to achieve this elevation (mean difference +0.42 Kgf, p < 0.001), the force was spread over a greater area (6.97 cm2 versus 2.0 cm2). Therefore, mean pressures applied to the foetal head were lower (mean difference -2.3 Kg cm2, p < 0.001). The first uses of the Tydeman Tube in clinical practice were described. Clinicians found it easy to use and effective (mean score 7.7/10). The Tydeman Tube is an effective tool for delivering the impacted foetal head on a simulator and its initial use in clinical practise has proved positive.

Implementation of warning tool to improve maternal newborn health outcomes in a developing country.

OBJECTIVE: To improve health outcomes through the implementation of national early warning sign tool for babies delivered through emergency caesarean section in off-work hours. METHODS: This comparative clinical study was conducted at the Aga Khan Hospital for Women and Children, Karachi, from April to August 2014, and comprised women who had an emergency caesarean section. Maternal and perinatal outcomes were compared of patients in Group A and Group B which represented individuals before and after the implementation of the national early warning score respectively. RESULTS: Of the 200 participants, there were 100(50%) in each group. The overall mean age was 26.79±5.10 years. The mean age was 26.3±5 years in Group A, and 27.2±5 years in Group B (p=0.25). The two groups were also comparable in terms of parity (p=0.77) and co-morbidities (p =0.51). There was no stillbirth or maternal death, but decline in complications due to post-partum haemorrhage (p=0.00) was observed due to early recognition and timely management. None of the women required referral to higher facility. CONCLUSIONS: National early warning score was found to be a practical early warning tool for obstetric population.
