Efficacy of cola ingestion for oesophageal food bolus impaction: open label, multicentre, randomised controlled trial.

OBJECTIVE: To determine the efficacy and safety of cola in resolving complete oesophageal food bolus impaction. DESIGN: Open label, multicentre, randomised controlled trial. SETTING: Emergency departments of five Dutch hospitals at the secondary and tertiary level, between 22 December 2019 and 16 June 2022. PARTICIPANTS: 51 adults presenting with complete oesophageal food bolus impaction, defined as a sudden inability to pass saliva after consumption of foods. Patients who ingested meat that contained bones, and patients with an American Society of Anesthesiologists (ASA) physical status classification of IV or higher were excluded. INTERVENTIONS: 28 patients in the intervention group were instructed to consume 25 mL cups of cola at intervals up to a maximum total volume of 200 mL. 23 patients in the control group awaited spontaneous passage. In either group, if complete resolution of symptoms did not occur, endoscopic removal was performed following current guidelines: within 6 hours for patients with complete obstruction, and within 24 hours for partial obstruction. In case of complete resolution of symptoms, elective diagnostic endoscopy was required. MAIN OUTCOME MEASURES: Improvement of oesophageal food bolus obstruction as reported by patients (ie, aggregate of complete and partial passage), and evaluation of complete passage. The secondary outcome was any intervention related adverse event. RESULTS: Cola did not have a meaningful effect on the improvement of food bolus obstruction (17/28 (61%) intervention v 14/23 (61%) control; odds ratio 1.00, 95% confidence interval 0.33 to 3.1; relative risk reduction 0.0, 95% confidence interval -0.55 to 0.36; P>0.99). Complete passage was reported more often in the intervention group but this difference was not significant (12/28 (43%) intervention v 8/23 (35%) control; odds ratio 1.4 (0.45 to 4.4); relative risk reduction -0.23 (-1.5 to 0.39); P=0.58). No severe adverse events occurred. However, six (21%) patients in the intervention group experienced temporary discomfort after drinking cola. CONCLUSIONS: In this study, cola consumption did not lead to a higher rate of improvement of complete oesophageal food bolus impaction. Given the lack of adverse events in the treatment group and some events of resolution after treatment, cola might be considered as a first line treatment, but should not delay any planning of endoscopic management.

Could we use the comfort score instead of the numeric rating pain score? A proof of concept pilot study.

INTRODUCTION: Asking patients about pain in the Emergency Department (ED) when deriving a pain score may aggravate perception of pain due to the nocebo-effect. A strategy for diminishing this nocebo-effect is cognitive reframing. Cognitive reframing of the frequently used pain score (PS) in the ED could theoretically be obtained by using the comfort score (CS). The aim of this study was to evaluate whether or not the CS and PS are interchangeable and therefore, whether or not the CS could safely be used in ED patients. METHODS: In this prospective pilot study we enrolled patients with pain visiting the ED. Participants were asked for both PS and CS in randomized order. CS were inverted (ICS) and compared with PS using the using the Wilcoxon signed rank test. Secondarily we evaluated for patient score preference. RESULTS: In total 100 patients were enrolled. The median PS in these participants was 6 (IQR 4-7) and median ICS was 5 (IQR 3-6). In total, 15 (15%) of the PS and ICS were identical Medians did not differ significantly (p = .115). In 33% of the participants the total difference between the PS and ICS was >2. Participants preferred to be asked for PS over CS (43 vs 15%, p < .00). CONCLUSION: This proof of concept study suggest interchangeability of the PS and the ICS in patients with pain in the ED. However, while not statistically significant, 33% of the patients had a possible clinical significant difference in score outcome, potentially over- or underestimating the patients pain. Whether or not this can be used as a tool for cognitive reframing to reduce perception of pain and medication consumption has yet to be studied.

Maternal mortality due to cardiovascular disease in the Netherlands: a 21-year experience.

OBJECTIVE: Cardiovascular disorders are the leading cause of indirect maternal mortality in Europe. The aim of this study is to present an extensive overview concerning the specific cardiovascular causes of maternal death and to identify avoidable contributing care factors related to these deaths. METHODS: We assessed all cases of maternal death due to cardiovascular disorders collected by a systematic national confidential enquiry of maternal deaths published by the Dutch Maternal Mortality and Morbidity Committee on behalf of the Netherlands Society of Obstetrics and Gynaecology over a 21-year period (1993-2013) in the Netherlands. RESULTS: There were 96 maternal cardiovascular deaths (maternal mortality rate due to cardiovascular diseases 2.4/100,000 liveborn children). Causes were aortic dissection (n = 20, 21%), ischaemic heart disease (n = 17, 18%), cardiomyopathies (including peripartum cardiomyopathy and myocarditis, n = 20, 21%) and (unexplained) sudden death (n = 27, 28%). Fifty-five percent of the deaths occurred postpartum (n = 55, 55%). Care factors that may have contributed to the adverse outcome were identified in 27 cases (28%). These factors were patient-related in 40% (pregnancy against medical advice, underestimation of symptoms) and healthcare-provider-related in 60% (symptoms not recognised, delay in diagnosis, delay in referral). CONCLUSION: The maternal cardiovascular mortality ratio is low in the Netherlands and the main causes of maternal cardiovascular mortality are in line with other European reports. In a minority of cases, care factors that were possibly preventable were identified. Women with cardiovascular disease should be properly counselled about the risks of pregnancy and the symptoms of complications. Education of care providers regarding the incidence, presentation and diagnosis of cardiovascular disease during pregnancy is recommended.

'PARAMEDIC-2: Big study, small result'.

The PARAMEDIC-2 trial demonstrated that the use of adrenaline compared with placebo in out-of-hospital cardiac arrest (OHCA) resulted in a small increase in 30-day survival, but was associated with a higher number of survivors with severe neurological impairment. These findings received a lot of attention, and generated a widespread discussion about the role of adrenaline in cardiac arrest. In this point of view, we aim to place the PARAMEDIC-2 results in the right perspective by comparing the relative effect of adrenaline to other determinants of cerebral blood flow.

[Myocardial contusion following trauma]. / Hartcontusie na een trauma.

BACKGROUND: Myocardial contusion is a potentially life threatening condition, which should be considered in patients with a compatible thoracic trauma. Guidelines for diagnosis and determination of management are non-existent. CASE DESCRIPTION: A 51-year-old man arrived at the accident and emergency department with thoracic trauma after being knocked down by a bus. A myocardial contusion was diagnosed based on the ECG and elevated high-sensitivity (hs) troponin levels. Cardiac ultrasound revealed no abnormalities. No complications occurred during 48 hours of cardiac monitoring. CONCLUSION: In patients with thoracic trauma, a combination of ECG abnormalities and raised hs troponin levels indicates myocardial contusion. Cardiac ultrasound is required in these patients if they are haemodynamically instable or suffer clinical deterioration. Observation using cardiac rhythm monitoring is necessary in all patients with myocardial contusion, because of the risk of complications such as life-threatening cardiac arrhythmias.

Pregnancy-related myocardial infarction.

INTRODUCTION: The risk of acute myocardial infarction in young women is low, but increases during pregnancy due to the physiological changes in pregnancy, including hypercoagulability. Ischaemic heart disease during pregnancy is not only associated with increased maternal morbidity and mortality, but also with high neonatal complications. Advancing maternal age and other risk factors for cardiovascular diseases may further increase the risk of ischaemic heart disease in young women. METHODS: We searched the coronary angiography database of a Dutch teaching hospital to identify women with acute myocardial infarction who presented during pregnancy or postpartum between 2011 and 2013. RESULTS: We found two cases. Both women were in their early thirties and both suffered from myocardial infarction in the postpartum period. Acute myocardial infarction was due to coronary stenotic occlusion in one patient and due to coronary artery dissection in the other patient. Coronary artery dissection is a relatively frequent cause of myocardial infarction during pregnancy. Both women were treated by percutaneous coronary intervention and survived. CONCLUSION: Physicians should be aware of the increased risk of myocardial infarction when encountering pregnant or postpartum women presenting with chest pain.

Ischaemic heart disease during pregnancy or post-partum: systematic review and case series.

The risk of manifestations of ischaemic heart disease (IHD) in fertile women is elevated during pregnancy and the post-partum period. With increasing maternal age and a higher prevalence of cardiac risk factors, the incidence of IHD during pregnancy is rising. However, information in the literature is scarce. We therefore performed a retrospective cohort study and systematically reviewed the overall (1975-2013) and contemporary (2005-2013) literature concerning IHD presenting during pregnancy or in the post-partum period. We report two cases of IHD with atypical presentation during pregnancy or post-partum. In our review, we describe 146 pregnancies, including 57 contemporary cases (2005-2013). Risk factors for IHD were present in 80 %. Of the cases of IHD, 71 % manifested in the third trimester or the post-partum period, and 95 % presented with chest pain. The main cause was coronary dissection (35 %), or thrombus/emboli (35 %) in the more contemporary group. Maternal mortality was 8 % (6 % in the contemporary group), and the main cardiac complication was ventricular tachycardia (n = 17). Premature delivery rate was 56 %, and caesarean section was performed in 57 %. Perinatal mortality was 4 %. In conclusion, IHD during pregnancy or in the post-partum period has high maternal mortality and morbidity rates. Also, premature delivery and perinatal mortality rates are high.
