Use of Prophylactic Parenteral Tranexamic Acid for Reduction of Blood Loss During and After Caesarean Section: A Double-Blind Randomized Controlled Study.

BACKGROUND: Haemorrhage is a leading cause of maternal mortality. The prophylactic use of tranexamic acid during vaginal delivery or caesarean section has the potential to reduce blood loss and postpartum anaemia. OBJECTIVE: To determine the effectiveness and safety of tranexamic acid in reducing blood loss during and within twenty-four hours after a caesarean section. METHODS: This was a randomised controlled study of two hundred and eighty-four (284) pregnant women booked for caesarean section at the University of Nigeria Teaching Hospital (UNTH), Ituku Ozalla, Enugu, Nigeria. The women were randomised into two groups: the intervention group (n = 142) that received intraoperative tranexamic acid with routine post-delivery oxytocin injection and the control group (n =142) that received placebo with routine post-delivery oxytocin. Blood loss was assessed both intra and post-operatively using a standard technique. RESULTS: The mean intraoperative blood loss was significantly lower in the intervention group compared to the control group (435.9±34 vs. 918±258.7, P=0.036). Similarly, the postoperative blood loss within twenty-four hours of surgery was significantly less in the intervention compared to the control group (232.71±67.4 vs. 717±317.6, P=0.031). The incidences of postoperative anaemia and blood transfusion intra or postoperatively were also significantly less in the intervention group compared to the control group (33.2% vs. 48.6; RR = 0.623; 95% CI = 0.46-0.84; p = 0.002, and 6.3% vs 24.6%: RR = 0.257; 95%CI = 0.13-0.52; P= < 0.001, respectively). There were no differences in the incidences of maternal and neonatal complications. CONCLUSION: The use of prophylactic parenteral tranexamic acid significantly reduces blood loss during and after caesarean section. It is therefore recommended in our obstetric practice as it has the potential to reduce the incidence of postpartum anaemia.

CONTEXTE: L'hémorragie est l'une des principales causes de mortalité maternelle. L'utilisation prophylactique de l'acide tranexamique lors d'un accouchement par voie basse ou d'une césarienne a le potentiel de réduire la perte de sang et l'anémie post-partum. OBJECTIF: Déterminer l'efficacité et la sécurité de l'acide tranexamique dans la réduction de la perte de sang pendant et dans les vingt-quatre heures suivant une césarienne. MÉTHODES: Cette étude contrôlée randomisée a inclus deux cent quatre-vingt-quatre (284) femmes enceintes prévues pour une césarienne à l'Hôpital Universitaire du Nigeria (UNTH), Ituku Ozalla, Enugu, Nigéria. Les femmes ont été randomisées en deux groupes : le groupe d'intervention (n = 142) qui a reçu de l'acide tranexamique en peropératoire avec une injection d'oxytocine post-accouchement de routine et le groupe témoin (n = 142) qui a reçu un placebo avec l'oxytocine de routine post-accouchement. La perte de sang a été évaluée pendant l'opération et après l'opération à l'aide d'une technique standard. RÉSULTATS: La perte de sang moyenne peropératoire était significativement plus faible dans le groupe d'intervention par rapport au groupe témoin (435,9±34 vs. 918±258,7, P=0,036). De même, la perte de sang postopératoire dans les vingt-quatre heures suivant l'opération était significativement plus faible dans le groupe d'intervention par rapport au groupe témoin (232,71±67,4 vs. 717±317,6, P=0,031). Les incidences d'anémie postopératoire et de transfusion sanguine pendant ou après l'opération étaient également significativement plus faibles dans le groupe d'intervention par rapport au groupe témoin (33,2% vs. 48,6%; RR = 0,623; IC 95% = 0,46-0,84; p = 0,002, et 6,3% vs. 24,6%: RR = 0,257; IC 95% = 0,13-0,52; P= < 0,001, respectivement). Il n'y avait pas de différences dans les incidences de complications maternelles et néonatales. CONCLUSION: L'utilisation prophylactique d'acide tranexamique parentéral réduit significativement la perte de sang pendant et après une césarienne. Il est donc recommandé dans notre pratique obstétricale, car il a le potentiel de réduire l'incidence de l'anémie post-partum. MOTS-CLÉS: Acide tranexamique, Perte de sang intrapartum, Hémorragie post-partum, Anémie.

Protocol for a feasibility multi-centre randomised controlled trial of a pre-operative two-week very low-calorie diet to reduce steatosis prior to liver resection (RESOLVE).

BACKGROUND: Hepatic steatosis (HS) increases morbidity and mortality associated with liver surgery (LS). Furthermore, patients with HS are more likely to require a blood transfusion, which is associated with worse short and long-term outcomes. Patients with HS requiring LS receive no specific dietary treatment or advice. A very low-calorie diet (VLCD) is commonly used before gallbladder and bariatric surgery to reduce liver volumes and associated intraoperative morbidity. These diets typically provide 800-1200 kcal/day over a 2-4-week period. Limited evidence suggests that a VLCD in patients with LS may result in better outcomes. METHODS: This study aims to test the feasibility of delivering a multi-centre randomised clinical trial to compare a dietary intervention (VLCD plus motivational instructions) versus treatment as usual (TAU) in people with HS having LS. This study will provide high-quality data to estimate screening rates, recruitment, randomisation, retention, and intervention adherence. The study will also determine the definitive trial's most clinically relevant primary outcome. The study will also estimate resource use and costs associated with the delivery of the intervention. Seventy-two adults ≥ 18 who are scheduled to undergo elective LS and have a magnetic resonance imaging (MRI) identified HS will be recruited. Acceptability to the dietary intervention will be evaluated with food diaries and focus groups. Clinical and patient-reported outcomes will be collected at baseline, pre- and post-surgery, day of discharge, plus 30- and 90-day follow-up. DISCUSSION: This feasibility study will provide data on the acceptability and feasibility of a dietary intervention for patients with HS having LS. The intervention has been developed based on scientific evidence from other clinical areas and patient experience; therefore, it is safe for this patient group. Patients with experience of LS and VLCDs have advised throughout the development of the study protocol. The findings will inform the design of a future definitive study.

Twin pregnancy and postpartum haemorrhage: a systematic review and meta-analysis.

BACKGROUND: Postpartum haemorrhage (PPH) continues to stand as the primary cause of maternal morbidity and mortality post-delivery, with twin pregnancies carrying a heightened risk of PPH compared to singleton deliveries. OBJECTIVES: To investigate the incidence of primary PPH among twin pregnancies and report on maternal and peripartum characteristics within this population. METHODS: A literature search was conducted using data from PubMed, EMBASE, Cochrane, Scopus, and Web of Science. The search aimed to identify studies concerning mothers with twin pregnancies and postpartum haemorrhage (PPH) from the inception of each respective database to June 8th, 2023. Pooled means and proportions were analyzed using the generic inverse variance method. This review was registered prospectively with PROSPERO (CRD42023427192). RESULTS: A total of 21 studies involving 23,330 twin pregnant patients were included. Incidence of PPH for vaginal delivery and Caesarean delivery (CS) was found to be 10.9% (95% CI: -0.017, 0.235, I2 = 96%) and 27.0% (95% CI: 0.180, 0.359, I2 = 99%) respectively. In vitro fertilization (IVF) was the most common conception method at 62.0% (95% CI: 0.448, 0.792, I2 = 100%) with 81.1% (95% CI: 0.708, 0.915, I2 = 100%) of twins being dichorionic diamniotic. CONCLUSION: This meta-analysis demonstrated more than one in ten vaginal deliveries and over one in four cesarean sections result in PPH for twin pregnancies. IVF is the predominant method of conception in this patient group and seems to contribute to subsequent PPH risk in specific mothers. While preliminary, these findings underscore the necessity for further well-designed and high-quality studies to validate these results.

Assisted reproductive technology and prolonged third stage of labour: a multicentre study in Japan.

RESEARCH QUESTION: What are the risk factors for a prolonged third stage of labour, closely related to postpartum haemorrhage, and what is the effect of assisted reproductive technology (ART) on the third stage of labour? DESIGN: Clinical data of women who delivered vaginally at term at 12 primary maternity hospitals in Japan (2010-2018) (n = 25,336) were obtained; 1148 (4.5%) conceived through ART and 2246 (8.9%) through non-ART treatments. The risk of a prolonged third stage of labour (defined as ≥20 min) was evaluated by univariable and multivariable regression analyses. Adjusted odds ratios (aOR) of a prolonged third stage of labour were evaluated, stratified by the type of ART, with natural conception as a reference. RESULTS: Multivariable analysis showed that pregnancy achieved through ART (aOR 4.38, 95% CI 3.12 to 6.15), history of spontaneous miscarriage (OR 1.40, 95% CI 1.06 to 1.84) and prolonged labour (OR 1.52, 95% CI 1.09 to 2.12) were identified as independent risk factors. Frozen embryo transfer (FET), FET in a hormone replacement cycle (HRC-FET) and blastocyst-stage embryo transfer were significantly associated with a prolonged third stage of labour (aOR 4.07, 95% CI 2.75 to 6.04, aOR 4.11, 95% CI 2.58 to 6.57 and aOR 2.13, 95% CI 1.15 to 3.95, respectively). No significant difference was observed in the duration of third stage of labour between natural conception and non-ART treatment (P = 0.61). CONCLUSION: Pregnancy achieved through ART, particularly FET, HRC-FET and blastocyst-stage embryo transfer, was a significant risk factor for a prolonged third stage of labour.

Trial of the Cerebral Perfusion Response to Sodium Nitrite Infusion in Patients with Acute Subarachnoid Haemorrhage using Arterial Spin Labelling MRI.

Aneurysmal subarachnoid haemorrhage (SAH) is a devastating subset of stroke. One of the major determinants of outcome is an evolving multifactorial injury occurring in the first 72 hours, known as early brain injury. Reduced nitric oxide (NO) bioavailability and an associated disruption to cerebral perfusion is believed to play an important role in this process. We sought to explore this relationship, by examining the effect on cerebral perfusion of the in vivo manipulation of NO levels using an exogenous NO donor (sodium nitrite). We performed a double blind placebo controlled randomised experimental medicine study of the cerebral perfusion response to sodium nitrite infusion during the early brain injury period in 15 low grade (World Federation of Neurosurgeons grade 1-2) SAH patients. Patients were randomly assigned to receive sodium nitrite at 10 mcg/kg/min or saline placebo. Assessment occurred following endovascular aneurysm occlusion, mean time after ictus 66h (range 34-90h). Cerebral perfusion was quantified before infusion commencement and after 3 hours, using multi-post labelling delay (multi-PLD) vessel encoded pseudocontinuous arterial spin labelling (VEPCASL) magnetic resonance imaging (MRI). Administration of sodium nitrite was associated with a significant increase in average grey matter cerebral perfusion. Group level voxelwise analysis identified that increased perfusion occurred within regions of the brain known to exhibit enhanced vulnerability to injury. These findings highlight the role of impaired NO bioavailability in the pathophysiology of early brain injury.

Emergency of oral haemorrhage: Retrospective study over 2 years.

INTRODUCTION: Oral haemorrhages (OH) represent a relatively rare reason for an emergency consultation, among dental pain, infectious processes and traumas. Various haemorrhagic risk factors are described, particularly those related to a general medical context or local factors. It is common to associate OH with haemorrhagic risk patients. Current studies mainly focus on patients considered at risk, but there is limited data on the characteristics of OH in patients without known haemorrhagic risk. METHOD: We conducted a 2-year retrospective study in a dental emergency department to identify OH occurring in patients without known haemorrhagic risk and to study their characteristics. RESULTS: OH accounted for approximately 2% of the reasons for consultation among all consultations carried out for dental emergencies. Their frequency was similar in the population of patients without hemorrhagic risk and those with a confirmed risk. They mainly occurred in young patients, without medical history. They also led to the diagnosis of an underlying pathology in about 1% of cases. CONCLUSION: This study underscores the importance of accurately documenting patients' medical history during preoperative consultations, as well as identifying associated risk factors. It also highlights that OH can be an early sign of a systemic disorder.

Mechanism and application of immune interventions in intracerebral haemorrhage.

Despite stroke being one of the major and increasing burdens to global health, therapeutic interventions in intracerebral haemorrhage (ICH) continue to be a challenge. Existing treatment methods, such as surgery and conservative treatment have shown limited efficacy in improving the prognosis of ICH. However, more and more studies show that exploring the specific process of immune response after ICH and taking corresponding immunotherapy may have a definite significance to improve the prognosis of cerebral haemorrhage. Therefore, immune interventions are currently under consideration as therapeutic interventions in the ICH. In this review, we aim to clarify unique immunological features of stroke, and consider the evidence for immune interventions. In acute ICH, activation of glial cells and cell death products trigger an inflammatory cascade that damages vessels and the parenchyma within minutes to hours of the haemorrhage. Immune interventions that ameliorate brain inflammation, vascular permeability and tissue oedema should be administered promptly to reduce acute immune destruction and avoid subsequent immunosuppression. A deeper understanding of the immune mechanisms involved in ICH is likely to lead to successful immune interventions.

Severe bleeding events among critically ill patients with haematological malignancies.

BACKGROUND: Bleeding events are common complications in critically ill patients with haematological malignancies. The objective of this study was to assess the incidence and identify determinants of ICU-acquired severe bleeding events in critically ill patients with haematological malignancies. We conducted a single-center retrospective study including all adult patients with a history of haematological malignancy requiring unplanned ICU admission over a 12-year period (2007-2018). The primary endpoint was the occurrence of ICU-acquired (i.e. after the first 24 h in the ICU) severe bleeding events, as defined as grades 3 or 4 of the World Health Organization classification. RESULTS: A total of 1012 patients were analysed, mainly with a diagnosis of lymphoma (n = 434, 42.9%) and leukaemia or myelodysplastic syndrome (n = 266, 26.3%). Most patients were recently diagnosed (n = 340, 33.6%) and under active cancer treatment within the last 3 months (n = 604, 59.7%). The main cause for admission was infection (n = 479, 47.3%), but a significant proportion of patients were admitted for a primary haemorrhage (n = 99, 10%). ICU-acquired severe bleeding events occurred in 109 (10.8%) patients after 3.0 days [1.0-7.0] in the ICU. The main source of bleeding was the gastrointestinal tract (n = 44, 40.3%). Patients experiencing an ICU-acquired severe bleeding event displayed prolonged in-ICU length of stay (9.0 days [1.0-6.0] vs. 3.0 [3.5-15.0] in non-bleeding patients, p < 0.001) and worsened outcomes with increased in-ICU and in-hospital mortality rates (55% vs. 18.3% and 65.7% vs. 33.1%, respectively, p < 0.001). In multivariate analysis, independent predictors of ICU-acquired severe bleeding events were chronic kidney disease (cause-specific hazard 2.00 [1.19-3.31], p = 0.008), a primary bleeding event present at the time of ICU admission (CSH 4.17 [2.71-6.43], p < 0.001), non-platelet SOFA score (CSH per point increase 1.06 [1.01-1.11], p = 0.02) and prolonged prothrombin time (CSH per 5-percent increase 0.90 [0.85-0.96], p = 0.001) on the day prior to the event of interest. CONCLUSIONS: Major bleeding events are common complications in critically ill patients with haematological malignancies and are associated with a worsened prognosis. We identified relevant risk factors of bleeding which may prompt closer monitoring or preventive measures.

Life-threatening event in laparoscopic hepatic surgery: Training curriculum on sudden hepatic artery haemorrhage.

BACKGROUND: Exposure of the hepatic artery is a fundamental step in many surgeries, during which iatrogenic hepatic artery injury may occur. Although the incidence of hepatic artery haemorrhage is low, its occurrence can lead to life-threatening haemorrhage. It is difficult and dangerous to accumulate clinical experience in laparoscopic hepatic artery repair in actual patients, and simulation training models for laparoscopic hepatic artery repair are currently lacking. In this study, a 3D printed model was designed to simulate the training curriculum for sudden hepatic artery haemorrhage, but whether training with the 3D printed model could yield superior skill improvement for surgeons remained to be determined. METHODS: A new 3D printed model was designed for this study. Surgeons from the General Surgery Department of Sir Run Run Shaw Hospital participated in this simulation training. The surgical performance of each model was compared, and the authenticity of the model was evaluated and mechanically tested. RESULTS: Experienced surgeons performed better on the 3D printed model. After repeated training, inexperienced surgeons showed significant improvement of their laparoscopic hepatic artery repair skills. The authenticity of the model was generally satisfactory, but shortcomings persisted in the mechanical testing of artery wall tearing, necessitating further improvement. CONCLUSIONS: Few studies have investigated laparoscopic simulation training for sudden hepatic artery haemorrhage. This simulation model distinguishes surgeons with different levels of experience and allows those with less experience to improve their laparoscopic hepatic artery repair skills through training on the model.

The effect of frailty on mortality and functional outcomes in spontaneous intracerebral haemorrhage.

INTRODUCTION: Limited data in patients with spontaneous intracerebral haemorrhage (SICH) showed that frailty was associated with mortality; however, there was insufficient data on functional outcomes. This study aimed to investigate the effect of frailty on overall mortality and 90-day functional outcomes in SICH. MATERIALS AND METHODS: We conducted a retrospective study of 1223 patients diagnosed with SICH from January 2014 to December 2020. Frailty was defined as a clinical frailty scale (CFS) score of 4-9. Binary cut-offs were defined using receiver operating curve analysis. 90-day poor functional outcomes (PFO) were defined as modified Rankin Scale (mRS) ≥3, and utility-weighted mRS (UW-mRS) were based on previous validated studies respectively. Regression analyses were conducted to investigate the association between frailty and outcomes. Confounders adjusted for included demographics, cardiovascular risk factors and haematoma characteristics. RESULTS: 1091 patients met the inclusion criterion. 167 (15.3 %) had 30-day mortality and 730 (66.9 %) had 90-day PFO. Frailty was significantly associated with lower overall survival (HR: 1.54; 95 % CI: 1.11-2.14, p=0.010), 90-day PFO (OR: 1.90; 95 % CI: 1.32-2.74; p<0.001) and poorer UW-mRS (ß: -0.06; 95 % CI: (-0.08 to -0.04); p<0.001) even after adjusting for confounders. CONCLUSIONS: Frailty was significantly associated with greater mortality and PFO after incident SICH, even after adjusting for a priori confounders. Frail male individuals may be predisposed to poorer outcomes from higher prevalence of cortical atrophy. The use of CFS in younger individuals may aid management by predicting outcomes after incident SICH. Identifying frail individuals with incident SICH could aid in decision-making and the surgical management of SICH.

The non-haemorrhagic vagal response to trauma: a review of hypotensive and bradycardic responses to injury in the absence of bleeding.

PURPOSE: Trauma has the potential to cause haemorrhage, tissue damage, pain, visceral manipulation and psychological distress. Each of these consequences of trauma can cause changes in autonomic outflow, which dictates a patient's vital signs. Patients who are hypotensive and bradycardic due to a vagally mediated parasympathetic response to pain, psychological distress and visceral manipulation may be confused with those who exhibit bradycardia and hypotension following significant blood volume loss. METHODS: This review summarises literature that describes specific stimuli, patterns of injury and patient characteristics that are associated with a non-haemorrhagic vagal response to trauma. RESULTS: Twenty-six records described predominantly parasympathetic responses to trauma (both blunt and penetrating) and surgery ("iatrogenic trauma"). Such a non-haemorrhagic vagal response occurs following a wide variety of injury patterns. Patient age and sex are poor predictors of the likelihood of a non-haemorrhagic vagal response. The development and resolution of a non-haemorrhagic vagal response occurs over a heterogenous time period. It is unclear whether speed of onset and resolution is linked to the pattern of injury or other factors causing a predominantly parasympathetic response following non-haemorrhagic trauma. CONCLUSION: The pattern of injury, patient demographic and speed of onset / resolution associated with the non-haemorrhagic vagal response to trauma may is heterogenous. It is therefore challenging to clinically distinguish between the hypotensive bradycardia due to hypovolaemia secondary to haemorrhage, or a parasympathetic response to trauma in the absence of bleeding.

Efficacy study of neuronavigation-assisted stereotactic drilling of urokinase drainage versus craniotomy in the treatment of massive intracerebral haemorrhage in elderly patientsa.

To evaluate the efficacy of neuronavigation-assisted stereotactic drilling drainage compared with that of craniotomy in the treatment of massive intracerebral haemorrhage (ICH) in elderly patients. This was a randomized, controlled, blind endpoint clinical study. Elderly patients with massive ICH treated at our neurosurgery department, without the formation of brain herniation preoperatively, all underwent neurosurgical intervention. Patients were randomly assigned to two groups: the minimally invasive surgery (MIS) group, which received neuronavigation-assisted stereotactic drilling drainage, and the craniotomy haematoma removal surgery (CHRS) group. Patient characteristics, surgical anaesthesia methods, surgery duration, intraoperative bleeding volume, duration of ICU stay duration of hospital stay, complications, and modified Rankin scale (mRS) scores at 90 days posttreatment were compared between the two groups. Statistical analysis was performed on the collected data. A total of 67 patients were randomly assigned, with 33 (49.25%) in the MIS group and 34 (50.75%) in the CHRS group. Compared with the CHRS group, the MIS group had advantages, including the use of local anaesthesia, shorter surgery duration, less intraoperative bleeding, shorter ICU stay, and fewer complications (P < 0.05). The MIS group had a significantly improved patient prognosis at 90 days (mRS 0-3). However, there were no significant differences in hospital stay or 90-day survival rate between the two groups (P > 0.05). For elderly patients with massive ICH without brain herniation, stereotactic drilling drainage is a simple surgical procedure that can be performed under local anaesthesia. Patients treated with this approach seem to have better outcomes than those treated with craniotomy. In clinical practice, neuronavigation-assisted stereotactic drilling drainage is recommended for surgical treatment in elderly patients with massive ICH without brain herniation.Clinical trial registration number: NCT04686877.

A Retrospective Study of Brain-Heart Syndrome in Patients with Acute Cerebrovascular Diseases.

Objective: To investigate the clinical characteristics, risk factors and outcomes of brain-heart syndrome (BHS) in patients with acute cerebrovascular diseases (ACVDs). Methods: A retrospective analysis was conducted of 100 patients who were admitted to our hospital with ACVDs between January 2023 and December 2023. The demographic, clinical, laboratory and imaging data of the patients were collected, and the presence and severity of BHS were evaluated. The neurological and cardiac outcomes of the patients at discharge and at 12-month follow-up were also assessed. Results: Out of the 100 patients, 38% had BHS, classified as mild (18%), moderate (12%) and severe (8%). The most prevalent ACVDs were cerebral infarction (58%), cerebral haemorrhage (32%) and subarachnoid haemorrhage (10%). Cardiac complications included arrhythmia (26%), myocardial ischaemia (18%) and heart failure (10%). Patients with BHS had higher results for blood pressure, heart rate, white blood cell count, C-reactive protein, IL-6, D-dimer and troponin, more severe neurological deficits, higher mortality and poorer functional outcomes. Multivariable analysis identified age, hypertension, diabetes, coronary artery disease, prior cardiovascular events, cerebral haemorrhage, brainstem infarction and hypothalamic or insular lesions as independent risk factors for BHS. Conclusion: Brain-heart syndrome is a frequent, severe complication in patients with ACVD, linked with multiple risk factors and poor prognosis. Prompt diagnosis and treatment are crucial for improving patient outcomes.

Corneal vascularisation and haemorrhage associated with netarsudil drops.

We report an interesting case of superficial corneal vascularization along with haemorrhages and microcystic edema confined to the inferior cornea in a female patient that are clearly attributed to netarsudil eye drops which she had been instilling for the last 8 weeks . Complete regression of all these corneal changes was noted after 3 months of discontinuation of this Rho kinase inhibitor. This is a unique finding and to our knowledge ; has not been reported so far.

Dengue encephalitis - An unusual case series.

Dengue infection can take on many different forms, ranging from no symptoms to a mild fever, all the way to a severe condition known as dengue shock syndrome. Although the typical symptoms of dengue are well known, the virus can also cause rare neurological complications. Dengue encephalitis is a severe form of neuroinvasive dengue that can be fatal as the virus directly affects the central nervous system. This case series provides a comprehensive overview of dengue, its clinical spectrum, and the potential for severe neurological complications such as dengue encephalitis. It highlights the importance of considering dengue as a possible diagnosis in patients with encephalitis, particularly during a dengue epidemic.

Traditional craniotomy versus current minimally invasive surgery for spontaneous supratentorial intracerebral haemorrhage: A propensity-matched analysis.

BACKGROUND: Minimally invasive surgery (MIS) and craniotomy (CI) are the current treatments for spontaneous supratentorial cerebral haemorrhage (SSTICH). AIM: To compare the efficacy and safety of MIS and CI for the treatment of SSTICH. METHODS: Clinical and imaging data of 557 consecutive patients with SSTICH who underwent MIS or CI between January 2017 and December 2022 were retrospectively analysed. The patients were divided into two subgroups: The MIS group and CI group. Propensity score matching was performed to minimise case selection bias. The primary outcome was a dichotomous prognostic (favourable or unfavourable) outcome based on the modified Rankin Scale (mRS) score at 3 months; an mRS score of 0-2 was considered favourable. RESULTS: In both conventional statistical and binary logistic regression analyses, the MIS group had a better outcome. The outcome of propensity score matching was unexpected (odds ratio: 0.582; 95%CI: 0.281-1.204; P = 0.144), which indicated that, after excluding the interference of each confounder, different surgical modalities were more effective, and there was no significant difference in their prognosis. CONCLUSION: Deciding between MIS and CI should be made based on the individual patient, considering the hematoma size, degree of midline shift, cerebral swelling, and preoperative Glasgow Coma Scale score.

High-risk factors for massive haemorrhage in medical abortion patients with missed miscarriage.

BACKGROUND: Recently, the incidence of missed miscarriage has gradually increased, and medical abortion is a common method to terminate a pregnancy. In the process of medical abortion, massive vaginal bleeding takes place, leading to emergency surgical haemostasis. Emergency surgery may produce infection and organ damage. Our study aimed to investigate the high-risk factors for massive haemorrhage during a medical abortion. METHODS: A total of 1062 missed miscarriage patients who underwent medical abortion participated in this retrospective study. According to the amount of bleeding, the patients were divided into a massive haemorrhage group and a control group. By comparing the general conditions of the two groups, such as fertility history, uterine surgery history, uterine fibroids, etc., the high-risk factors for massive haemorrhage during medical abortion were identified. RESULTS: Relative to the control group, the massive haemorrhage group exhibited a higher proportion of patients with a previous artificial abortion (51.9% vs. 38.1%, P = 0.001). Additionally, the massive haemorrhage group had a lower percentage of first-time pregnant women (32.1% vs. 40.4%) and a higher proportion of women with shorter pregnancy intervals (44.9% vs. 33.1%, P = 0.03). Furthermore, there were notable differences between the two groups regarding maximum fibroid size, the duration of amenorrhea, and gestational week (P < 0.05). CONCLUSION: In this study, we determined that a history of artificial abortion and an amenorrhea duration of > 11 weeks represented high-risk factors for massive vaginal bleeding during medical abortion in missed miscarriage patients.

REBOA in trauma: a life-saving intervention or a spectacular failure?

PURPOSE: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a controversial haemorrhage control intervention often touted as the bridge to definitive haemorrhage control. This review summarizes the evolution of REBOA from its inception to the latest applications with an emphasis on clinical outcomes. METHODS: This is a narrative review based on a selective review of the literature. RESULTS: REBOA remains a rarely utilized intervention in trauma patients. Complications have remained consistent over time despite purported improvements in catheter technology. Ischemia-reperfusion injuries, end-organ dysfunction, limb ischemia, and amputations have all been reported. Evidence-based guidelines are lacking, and appropriate indications and the ideal patient population for this intervention are yet to be defined. CONCLUSION: Despite the hype, purported technological advancements, and the mirage of high-quality studies over the last decade, REBOA has failed to keep up to its expectations. The quest to find the solution for uncontrolled NCTH remains unsolved.

Severe Coagulopathy and Intra-Alveolar Haemorrhage Due to Fat Malabsorption in Celiac Disease.

Celiac disease, a prevalent autoimmune disorder, can present atypically with fat malabsorption and coagulopathy due to vitamin K malabsorption. A 64-year-old male presented with haemoptysis and severe anaemia (Hb 6 g/dl). Despite normal previous coagulation tests, admission laboratory tests revealed an international normalised ratio (INR) of 7.0 and iron deficiency anaemia. Initial blood products and vitamin K treatment corrected the INR temporarily, but the patient's haemoptysis returned, and his INR values continued to rise. Further investigation revealed celiac disease with fat malabsorption, leading to vitamin K malabsorption and along with a previously prescribed antiplatelet aggregation therapy, this led to diffuse alveolar haemorrhage. A gluten-free diet and vitamin supplementation normalised the patient's INR and stopped the bleeding. This case highlights the importance of considering celiac disease in unexplained coagulopathies and the effectiveness of dietary management. LEARNING POINTS: Celiac disease can cause severe coagulopathy due to fat malabsorption and vitamin K deficiency.High suspicion is required for atypical presentations of celiac disease.A gluten-free diet is essential for managing celiac disease and normalising coagulation profiles.

A comprehensive approach to continuous quality improvement of massive transfusion by developing key performance indicators.

BACKGROUND AND OBJECTIVES: To develop key performance indicators (KPI) for use in quality assessment of our institutional goal-directed massive transfusion (GDMT). MATERIALS AND METHODS: A team comprising our transfusion and emergency medicine departments carried out a cross-sectional data analysis of GDMT in adult patients from January 2021 to December 2022. The study was rooted in the Define, Measure, Analyse, Improve, Control (DMAIC) approach. Features of KPIs were (a) importance, (b) scientific soundness and (c) feasibility. Study parameters were defined and analysed using measures of central tendencies and benchmark comparison. RESULTS: Ninety-two massive transfusion events occurred and 1405 blood components were used. Trauma was the leading cause, followed by postpartum haemorrhage and upper gastrointestinal bleeding. Appropriate GDMT activation was observed only in 43.47% of events. The turnaround time (TAT) was within the benchmark in 85.8% of events with an average of 16 ± 10 min. The average utilization of blood components was 20.5 (interquartile range [IQR] = 11.3) in the appropriate group and 5.5 (IQR = 4.25) in the inappropriate group with a wastage rate of 3.5%. Duration of activation was 6.19 ± 4.59 h, and the adherence to thromboelastography was 66.3%. Overall mortality was 45.65%, and the average duration of hospital stay was 6.1 ± 5.9 days. CONCLUSION: The KPIs developed were easy to capture, and the analysis provided a comprehensive approach to the quality improvement of the GDMT protocol.
