Basildon Hospitals Intrapartum Monitoring Strategy (BIMS) was introduced to address an increasing rate of babies diagnosed with hypoxic–ischaemic encephalopathy (HIE) and comprises intensive, physiology-based CTG training and a mandatory competency testing for all midwives and obstetricians. This combination aims to deepen the appreciation clinicians have for the intricacies of fetal monitoring and promotes consistency across the service. In our maternity unit, use of fetal ECG (STAN) was subsequently introduced to reduce the false-positive rate of CTG. The intensive training on physiological interpretation of CTG involves promoting a deeper understanding of fetal pathophysiology: instead of morphologically classifying decelerations as ‘early’, ‘variable’ and ‘late’, the underlying mechanism is explored as well as the fetal response to ongoing hypoxic or mechanical stresses. In addition, education focuses on the consideration of the features of type of intrapartum (acute, subacute or a gradually evolving) or chronic (long-standing) fetal hypoxia on the CTG trace and encourages differentiation of a compensatory fetal response from decompensation.

Intrauterine resuscitation refers to any intervention during labour carried out with the aim of increasing oxygen delivery to the fetus by improving fetoplacental circulation and thereby optimizing the intrauterine environment. The reversal of fetal hypoxia and acidosis may allow labour to continue safely, or optimize the fetal condition/well-being until urgent delivery is accomplished. If not corrected, continuation of fetal hypoxic stress may result in fetal decompensation leading to hypoxic–ischaemic injury. Prolonged decelerations occur due to an acute and profound fetal hypoxic stress secondary to reversible causes such as maternal hypotension, uterine hyperstimulation (hypertonus) often in response to oxytocin, sustained umbilical cord compression or due to irreversible causes such as cord prolapse, which may be amenable for intrauterine resuscitation. Rapid intravenous infusion of a crystalloid solution will help improve maternal venous return and cardiac output in the presence of maternal hypotension, and maternal repositioning may relieve aortocaval compression and improve maternal cardiac output, with resultant improvement in uteroplacental perfusion.

This case presents a clinical vignette of a 19-year-old woman with early pregnancy complicated by abdominal pain and vaginal bleeding. The learner is provided with an opportunity to formulate their own clinical presentation and differential, followed by an ideal presentation and note for comparison. Key points include the evaluation of ectopic pregnancy using transvaginal ultrasound and quantitative hCG, the importance of identifying right adnexal tenderness, and management strategies including consultation with obstetrics/gynecology and RhoGAM administration for Rh-negative patients. Timely recognition and intervention is critical to prevent rupture and life-threatening complications.

Fetal growth restriction (FGR) is defined as the inability of a fetus to achieve its genetic growth potential, and the aetiology is multifactorial. However, the most frequent aetiology is placental insufficiency, which results in fetal chronic hypoxia leading to FGR. FGR is associated with several short- and long-term adverse outcomes, especially stillbirth and cerebral palsy. Fetuses affected by chronic hypoxia undergo several adaptive mechanisms in order to secure enough oxygen and nutrient supply to the vital organs. These changes are responsible for some of the features observed in the antepartum cardiotocography (CTG) traces of FGR fetuses. Labour represents a stressful event for the fetoplacental unit, as uterine contractions are associated with an intermittent reduction of up to 60% of the uteroplacental perfusion, and therefore FGR fetuses with an antenatal placental insufficiency have an increased risk of intrapartum hypoxic–ischaemic injury. This is because the superimposed hypoxic stress of labour has the potential to exacerbate ongoing chronic hypoxia. Caution is warranted when using uterotonics as FGR fetuses may not tolerate additonal hypoixc stress.

In the high-pressure environment of the emergency department, your ability to deliver a clear, concise, and confident oral presentation can define both patient outcomes and professional credibility. This chapter explores the art and science of effective case presentations, offering a practical roadmap for developing structured, high-impact communication under pressure. Using the SBAR (situation, background, assessment, recommendation) framework, readers learn how to synthesize clinical information, prioritize life-threatening conditions, and communicate clearly across hierarchical and interdisciplinary teams. Emphasis is placed on situational awareness, clinical organization, composure under stress, and tailoring communication to the audience. Through both positive modeling and real-life “what not to do” examples, the chapter illustrates the pitfalls of vague, disorganized, or irrelevant presentations and guides learners in transforming their delivery into focused, efficient, and trusted exchanges. This is a teachable skill, and this chapter offers the foundation to help learners gain the confidence, clarity, and credibility needed to thrive in emergency medicine.

Chorioamnionitis (inflammation of the chorion and amnion) is a fetal disease, and the observed fetal heart rate (FHR) changes reflect the severity of infection in the fetal compartment. Transplacental passage of maternal infection (bacteria, their toxins and inflammatory cytokines) usually commences with the onset of maternal symptoms and signs (maternal tachycardia, pyrexia, being unwell), followed by the onset of a reactive fetal tachycardia (>10% increase in the baseline FHR as compared to the previously recorded baseline). The CTG trace will show changes in the FHR corresponding to the severity of fetal infections. Recent studies have shown good correlation between CTG features suggestive of chorioamnionitis as per physiological CTG interpretation and histopathological findings in the placenta, as well as interleukin-6 (IL-6) levels in the umbilical cord at birth. Experimental animal studies have confirmed that in the presence of fetal inflammatory cytokines or bacterial toxins, if there is a superimposed hypoxic stress, there is a significant increase in the risk of neurological injury.

Artifical stimulation of myometrial contractions to either commence labour and/or to augment ongoing uterine contractions may reduce fetal oxygenation due to the excessive compressions of maternal spiral arterioles and/or compression of the umbilical cord. Induction of labour (IOL) refers to an artificial initiation of labour by facilitating cervical ripening, and the commencement of uterine contractions when the continuation of pregnancy poses an increased risk to the health and well-being of the fetus and/or the mother. Augmentation of labour refers to the process of artificially stimulating the myometrium to increase the frequency, duration and intensity of uterine contractions when the labour has already commenced. It is indicated when labour is progressing slower than expected, and mechanical causes such as cephalopelvic disproportion (CPD) and a secondary arrest due to absolute or relative fetal macrosomia have been excluded. injudicious use of the agent used for induction/augmentation and/or hypersensitivity to the medication used may result in excessive uterine activity (frequency, duration and/or intensity of the contractions or an increase in the basal tone).

This case presents a clinical vignette of a 25-day-old infant brought to the ED with fever, lethargy, and poor feeding. The learner is provided an opportunity to develop their own diagnostic presentation and note, then compare it with an ideal standard. The case emphasizes the high-risk nature of febrile neonates and the importance of recognizing sepsis in this age group. A systematic approach is outlined, including the need for immediate attending notification, simultaneous history and physical exam, and initiation of a full septic workup (blood, urine, CSF) regardless of clinical appearance. The scenario illustrates the application of the American Academy of Pediatrics (AAP) guidelines, stressing early empiric antibiotic treatment and NICU admission. This case reinforces core principles in neonatal emergency care and the critical need for early intervention to prevent morbidity and mortality.

This clinical vignette centers on the emotionally charged task of delivering news of death to a patient’s family. After resuscitative efforts are exhausted, the emergency physician meets with the deceased patient’s daughter and her partner to explain what happened. The conversation emphasizes compassion, presence, and clear communication, while modeling professionalism and emotional stewardship. This case highlights the critical importance of knowing patients and families by name, setting, and tone; using the SPIKES framework; and recognizing “residue,” the emotional imprint of threshold moments. It offers a framework for navigating grief compassionately while caring for both the family and yourself in the process. It also introduces tools for reflection, including Dr. Cline’s DR5 framework, and invites learners to reframe suffering as a catalyst for resilience and growth.

Physiology-based interpretation of CTG reflects a journey back to the very foundation of clinical medicine taught in the first few years of medical school. This includes taking a good history, performing relevant clinical examination and investigations to arrive at a diagnosis (or a differential diagnosis), and then formulating an individualized management plan based on the diagnosis. Obstetric and medical history is the most crucial aspect of physiological interpretation of CTG traces which would entail scrutiny of the CTG trace for specific features to ensure timely and appropriate interventions. Clinical examination is vital as derangements of the maternal environment (e.g. pyrexia, hypoxia, dehydration, ketoacidosis, hypotension, abruption) may result in specific fetal heart rate changes. Timely and appropriate management depends on the specific diagnosis, and this invidualization of care is the key principle of physiology-based CTG training and interpretation. Therefore, it differs from most CTG guidelines that treat all human fetuses the same by recommending the same management for ‘suspicious’ or ‘pathological’ CTG traces.

ST waveform analysis (STAN) was introduced as a complement to cardiotocography (CTG) with the aim of reducing the false-positive rate of the CTG and thereby reducing the rate of intrapartum emergency caesarean sections and operative vaginal births. Moreover, it was hoped that STAN would also reduce the rate of hypoxic–ischaemic encephalopathy (HIE) and intrapartum-related perinatal deaths. However, since the introduction of this technology, which is based on sound physiological principles of determining the oxygenation of the ‘high-priority’ fetal central organ (i.e. the myocardium), the Achilles heel of STAN has been the use of a flawed CTG guideline which arbitrarily groups random features of the fetal heart rate into ‘normal, intermediary, abnormal’ categories. This approach not only increases the inter- and intra-observer variability leading to variation in clinical outcomes due to observed STAN events being erroneously considered as significant or non-significant due to the erroneous CTG interpretation, but these guidelines do not consider the features of pre-existing (chronic) hypoxia or fetal responses to ongoing hypoxic stress or features of fetal inflammation.

During the second stage of labour the transducer, which is designed to pick up the signals from the pulsations of fetal heart ventricles (using the Doppler technology), may erroneously pick up signals from the pulsating maternal iliac blood vessels. The expected features on the fetal heart rate (FHR) during the active second stage of labour when the hypoxic stress is maximum include decelerations (due to reduced uteroplacental circulation or umbilical cord compression) or a subacute hypoxic pattern. In contrast, due to pain, and maternal efforts, repetitive, large-amplitude accelerations will be observed if the maternal heart rate (MHR) is erroneously recorded as the FHR. The misinterpretation of MHR artefact as FHR can potentially mask an ongoing abnormal FHR trace, giving the appearance of a falsely reassuring trace. This can lead to increased perinatal morbidity and mortality due to the non-recognition of intrapartum hypoxia or fetal demise in the second stage. The ‘double mountain peak’ sign with high-amplitude accelerations coinciding with uterine contractions should arouse the suspicion of erroneous recording of MHR as FHR.

Fetal asphyxia leads to fetal compromise, which requires assessment, investigation and management by obstetric, anaesthetic, midwifery and neonatal staff. Failure to identify and correct the cause will result in decompensation of physiological responses (primarily redistribution of blood flow to preserve oxygenation of vital organs) resulting in permanent central nervous system and other organ damage or death to the fetus. Maternal resuscitation and subsequent optimization of placental perfusion can lead to significant improvements in the condition of the fetus. The provision of safe labour analgesia and anaesthesia for delivery is crucial as it may also significantly affect neonatal outcomes by transplacental drug transfer and altering maternal haemodynamics. The increasing trend in obese mothers may make anaesthetic interventions potentially more challenging. Obstetric anaesthetists are crucial members of the maternity multidisciplinary team (MDT) to improve maternal and perinatal outcomes, and in educating the maternity MDT in basic physiological principles to safeguard women and babies against historical, unscientific obstetric interventions which are potentially harmful.

This case presents a clinical vignette involving a nine-year-old boy with right lower-quadrant abdominal pain, allowing learners to create their own patient presentation and note before comparing against a model of effective communication and documentation. The presentation is consistent with acute appendicitis, confirmed through clinical findings, laboratory testing, and ultrasound imaging. Key teaching points include recognition of typical signs and symptoms in pediatric appendicitis, preferred imaging modalities in children, and the evolving discussion around operative versus nonoperative management. Learners are guided in balancing diagnostic accuracy, radiation avoidance, and shared decision-making with pediatric caregivers.

Vacuum cup and forceps blade application on the fetal head may lead to mechanical stimulation and activation of somatic or autonomic nervous system and changes in fetal heart rate (FHR). Use of the vacuum cup predominantly stimulates the sympathetic nervous system leading to an abrupt increase in the FHR, which appears to be secondary to pain and/or pressure. Forceps use results in increased variability (ZigZag pattern) most likely secondary to increased intracranial pressure as the forceps blades are locked and resultant autonomic instability. Understanding the FHR changes due to these mechanical effects is essential to avoid unnecessary panic and interventions, and the detrimental effects of birth trauma on ongoing fetal hypoxia and inflammation should be appreciated; caution should be exercised prior to attempting a potentially difficult operative vaginal birth in the presence of features suggestive of fetal neuroinflammation and/or decompensation of the CNS. Failed operative vaginal births may lead to an unnecessary emergency c-section with increased risks of maternal and perinatal morbidity and mortality.

Healthcare provision involves humans (clinicians and non-clinicians) working in a complex environment consisting of equipment, technology, organizational culture and attitudes and behaviours of fellow team members as well as their patients and families. Human factors refer to the intricate link between knowledge, skills and competencies, the environment in which clinicians work, their personal circumstances, and the nature of communication between team members. Possession of individual knowledge, skills and competencies alone will not lead to the desired clinical outcomes if all other aspects of human factors are not understood and rectified. Pereira et al. identified 12 key aspects of human factors that may contribute to poor outcomes relating to CTG interpretation, based on ‘Du Pont’s dirty dozen’ from the airline industry. Addressing these key areas where ‘human factors’ is essential to optimize perinatal outcomes. Four consecutive ‘Each Baby Counts’ (EBC) Reports have reported that >50% of all cases of severe intrapartum hypoxia-related brain injury and perinatal deaths in the UK was due to CTG misinterpretation/fetal scalp blood sampling.

This case presents a middle-aged man with acute nausea and vomiting after abruptly stopping chronic heavy alcohol use. Learners are invited to evaluate for alcohol withdrawal syndrome (AWS), assess CIWA score, and distinguish withdrawal from other potential causes of vomiting. The discussion focuses on recognizing moderate withdrawal symptoms, initiating benzodiazepine therapy, and preventing complications such as delirium tremens and Wernicke’s encephalopathy. Learners are guided through comprehensive history taking, including substance use patterns, and the importance of supportive care, including electrolyte correction, thiamine supplementation, and admission for close monitoring.

This clinical vignette presents a middle-aged woman with sharp right upper-quadrant pain, fever, and vomiting. The learner is given an opportunity to construct a differential diagnosis and diagnostic strategy. The case emphasizes acute cholecystitis, with discussion of risk factors, key physical findings such as a positive Murphy’s sign, and the role of right upper-quadrant ultrasound in diagnosis. Laboratory data support the inflammatory process with elevated WBC and liver enzymes. Learners are challenged to distinguish cholecystitis from biliary colic and other mimics including pancreatitis, gastritis, and gynecologic causes. The case concludes with initiation of antibiotics and surgical consultation, providing a clear example of coordinated diagnostic and interprofessional care.
