BACKGROUND
In a sedated patient, airway compression by a large mediastinal mass can cause acute fatal cardiopulmonary arrest. Extracorporeal membrane oxygenation (ECMO) has been investigated to protect the airway and provided cardiopulmonary stability. The use of ECMO in the management of mediastinal masses was reported, however, the management complicated by cardiopulmonary arrest is poorly documented.
CASE PRESENTATION
32-year-old female presented with acute onset of left arm swelling and subacute onset of dry cough. Further investigation showed a deep venous thrombosis in left upper extremity as well as a large mediastinal mass. She underwent mediastinoscopy with biopsy of the mass which was complicated by cardiopulmonary arrest secondary to airway obstruction by the mediastinal mass. Venoarterial ECMO was initiated, while concurrently treating with a chemotherapy. The mediastinal mass responded to the chemotherapy and reduced in size during 2 days of ECMO support. She was extubated successfully and decannulated after 2 days of ECMO and discharged later.
CONCLUSIONS
Extracorporeal membrane oxygenation can serve as a viable strategy to facilitate cardiopulmonary support while concurrently treating the tumor with chemotherapy, ultimately allowing for the recovery of cardiopulmonary function, and achieving satisfactory outcomes.

Randomized Controlled Trial
OBJECTIVES
To assess the effectiveness and safety of prone positioning in the treatment of neonatal respiratory distress syndrome (NRDS) using invasive respiratory support.
METHODS
A prospective study was conducted from June 2020 to September 2023 at Suining County People's Hospital, involving 77 preterm infants with gestational ages less than 35 weeks requiring invasive respiratory support for NRDS. The infants were randomly divided into a supine group (37 infants) and a prone group (40 infants). Infants in the prone group were ventilated in the prone position for 6 hours followed by 2 hours in the supine position, continuing in this cycle until weaning from the ventilator. The effectiveness and safety of the two approaches were compared.
RESULTS
At 6 hours after enrollment, the prone group showed lower arterial blood carbon dioxide levels, inspired oxygen concentration, oxygenation index, rates of tracheal intubation bacterial colonization, and Neonatal Pain, Agitation and Sedation Scale scores compared to the supine group (<0.05). There were no significant differences between the groups in terms of pH, arterial oxygen pressure, positive end-expiratory pressure, duration of mechanical ventilation, accidental extubation, ventilator-associated pneumonia, air leak syndrome, skin pressure sores, feeding intolerance, and grades II-IV intraventricular hemorrhage (>0.05).
CONCLUSIONS
Compared to supine positioning, prone ventilation effectively improves oxygenation, increases comfort, and reduces tracheal intubation bacterial colonization in neonates requiring mechanical ventilation for NRDS, without significantly increasing adverse reactions.

Review
Drowning is responsible for considerable morbidity and mortality worldwide, and it is estimated that 90% of drownings are preventable. Drowning is defined as "the process of experiencing respiratory impairment from submersion/immersion in liquid." Emergency providers should focus on airway management and rapid delivery of oxygen to interrupt the drowning process and improve patient outcomes. Patients with minimal or no symptoms do not require any specific diagnostic workup, aside from physical examination and 4 to 6 hours of observation prior to discharge. Patients with more severe symptoms may present with rales and foamy secretions, and should be managed with high-concentration oxygen and positive airway pressure.

Review
INTRODUCTION
Botulism is a serious condition that carries with it a high rate of morbidity and mortality.
OBJECTIVE
This review highlights the pearls and pitfalls of botulism, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence.
DISCUSSION
Botulism is a neuromuscular disorder caused by toxin production of clostridium species bacteria and is a challenging diagnosis that mimics several other conditions. Children account for the majority of patients, with a foodborne source most common, followed by wound sources, typically from intravenous drug injection. Classically, patients with botulism develop bilateral cranial nerve palsies and symmetric, bilateral, descending paralysis. However, patients may initially present with vague symptomatology, such as weakness and dry mouth, which can make diagnosis challenging. A careful history elucidating exposures such as intravenous drug use or consumption of non-commercial canned products can help differentiate botulism from other disorders causing neuromuscular weakness. If suspected, the Centers for Disease Control should be notified to mobilize antitoxin for treatment as soon as the diagnosis is suspected even prior to confirmatory testing. Antibiotics should be avoided in these patients, as they can potentiate toxin release, unless there is a concomitant infection requiring antibiotic therapy. Patients with botulism can develop respiratory compromise requiring emergent airway management. Prolonged neuromuscular blockade from botulism will lead to a variety of symptoms that require comprehensive intensive care unit level care.
CONCLUSION
An understanding of botulism and its many potential mimics can assist emergency clinicians in diagnosing and managing this deadly disease.

INTRODUCTION
An emergent front of neck airway (FONA) is needed when a 'can't intubate, can't oxygenate' crisis occurs. A FONA may also in specific cases be the primary choice of airway management. Two techniques exist for FONA, with literature favouring the surgical technique over the percutaneous. The reported need for a prehospital FONA is fortunately rare as the mortality has been shown to be high. Due to the low incidence, literature on FONA is limited with regards to different settings, techniques and operators. As a foundation for future research and improvement of patient care, we aim to describe the frequency, indications, technique, success, and outcomes of FONA in the Finnish helicopter emergency medical services (HEMS).
MATERIALS AND METHODS
This retrospective descriptive study reviews FONA performed at the Finnish HEMS during 1.1.2012 to 8.9.2019. The Finnish HEMS consists of six units, staffed mainly by anaesthesiologists. Clinical data was gathered from a national HEMS database and trough chart reviews. Data on mortality was obtained from a population registry. Only descriptive statistics were performed.
RESULTS
A total of 22 FONA were performed during the study period, 7 were primary and 14 performed after failure to intubate (missing data regarding indication for one attempt). This equals a 0.13 % (14/10,813) need for a rescue FONA and a rate of 0.20 % (22/10,813) FONA out of all advanced airway management. All but one FONA was performed using a surgical approach (20/21, 95 %, missing data = 1) and all were successful (22/22, 100 %). Indications were mainly cardiac arrest (10/22, 45 %) and trauma (6/22, 27 %), and the most common reason for a need for a secondary FONA was obstruction of airway by food or fluids (7/14, 50 %). On-scene mortality was 36 % (8/22) and 30-day mortality 90 % (19/21, missing data = 1).
CONCLUSION
The need for FONA is scarce in a HEMS system with experienced airway providers. Even though the procedure is successfully performed, the mortality is markedly high.

BACKGROUND
Twin pregnancies are associated with a high risk of perinatal mortality and morbidity. Late preterm or early term delivery is frequently performed to avoid unexpected fetal death in uncomplicated twin pregnancies. Nonetheless, delivery before full term is associated with neonatal respiratory complications. This study aimed to evaluate perinatal respiratory complications in twins delivered between 36 and 38 weeks of gestation.
METHODS
A retrospective cohort study was conducted on twins delivered between 36 and 38 weeks of gestation from January 2008 to June 2020. The primary outcomes were the incidence of composite neonatal respiratory morbidity, which included respiratory distress syndrome, transient tachypnea of the newborn, meconium aspiration syndrome, mechanical ventilation or continuous positive airway pressure according to gestational age at delivery, and chorionicity. The relationship between gestational age at delivery and composite neonatal respiratory morbidity was evaluated using multivariate logistic regression analysis adjusted for potential confounders.
RESULTS
This study included 1608 twins (614 monochorionic diamniotic twins, 994 dichorionic diamniotic twins). At 36, 37, and 38 weeks of gestation, the frequencies of composite neonatal respiratory morbidity were 19.4%, 10.7%, and 9.2% in dichorionic diamniotic twins and 13.6%, 8.7%, and 9.4% in monochorionic diamniotic twins, respectively. In dichorionic diamniotic twins, the composite neonatal respiratory morbidity rate was higher for twins delivered at 36 weeks of gestation than for those delivered at 37 weeks. No significant differences between monochorionic diamniotic twins were detected.
CONCLUSIONS
In uncomplicated dichorionic diamniotic twin pregnancies, delivery should be considered after 37 weeks of gestation to reduce neonatal respiratory complications.

BACKGROUND
This multicenter study examines the contemporary management of penetrating carotid artery injury (PCAI) to identify trends in management, outcomes, and to determine prognostic factors for stroke and death.
METHODS
Data from three large urban trauma centers in South Africa were retrospectively reviewed for patients who presented with PCAI from 2012 to 2020.
RESULTS
Of 149 identified patients, 137 actively managed patients were included. Twenty-four patients (17.9%) presented in coma and 12 (9.0%) with localizing signs (LS). CT angiography was performed on admission for 120 (87.6%) patients. Thirty patients (21.9%) underwent nonoperative management, 87 (63.5%) open surgery, and 20 (14.6%) endovascular stenting. Eighteen patients (13.1%) died, and 15 (12.6%) surviving patients had strokes. Ligation was significantly related to death and reperfusion to survival. A mechanism of gunshot wound, occlusive injuries, a threatened airway, a systolic blood pressure <90 mmHg, hard signs of vascular injury, a low GCS, coma, a CT brain demonstrating infarct, a high injury severity score and shock index, a low pH or HCO3, and an elevated lactate were significant independent prognostic factors for death. Ligation was unsurvivable in all patients with severe neurological deficits, whereas reperfusion procedures resulted in survival in 63% (12/19) patients with coma and 78% (7/9) with LS although with high stroke rates (coma: 25.0%, LS: 85.7%).
CONCLUSIONS
Outcomes in PCAI, including patients with severe neurological deficit and stroke, are better when reperfused. Reperfusion holds the best promise of survival and ligation should be reserved for technically inaccessible bleeding injuries.

BACKGROUND
The efficacy and safety of cuffed endotracheal tubes (ETTs) in neonates are still unclear, this study aimed to assess the efficacy of cuffed versus uncuffed ETTs in neonate undergoing noncardiac surgeries.
METHODS
Neonates scheduled for noncardiac surgeries were randomized into two groups according to the type of airway device during general anesthesia: cuffed ETT group (n = 60) and the uncuffed ETT group (n = 60). The primary outcome was the incidence of ETT exchange to find the appropriate ETT. Other outcomes included: duration of intubation, lung ultrasound score, and incidence of postoperative complications (croup, wheezes, hypoxia, etc.).
RESULTS
The frequency of ETT exchange was lower in the cuffed ETT group compared to the uncuffed one {1 (1.7%) vs. 28 (46.7%), p = .0001; relative risk [95% confidence interval]: 0.54 [0.43-0.69]}. Postoperative adverse events were comparable between both groups except for significantly higher post extubation croup in the uncuffed ETT group compared to the cuffed ETT {10 (16.7%) vs. 3(5%), p value = .04, relative risk (95% confidence interval): 1.14 (1-1.29)}.
CONCLUSION
In full term neonates undergoing noncardiac surgeries, the use of cuffed ETT was associated with less need to tracheal tube exchange and less incidence of postoperative croup, without increasing the postoperative respiratory complications compared to uncuffed ETT.

The aim of this clinical audit is to evaluate the characteristics of dental infections requiring hospitalisations, which may help improve preventative and management policies. This study retrospectively evaluated the records of patients admitted to the Nepean hospital, Kingswood, New South Wales, Australia, due to dental infections between 2018 and 2019. A total of 102 patients, mostly in their thirties with equal gender distribution, were admitted with dental infections, presenting with pain (100%), swelling (99%), trismus (40.2%), dysphagia (27.4%), fever (21%) [>37 °C], tachycardia (24.8%) and tachypnoea (9.3%). Most patients (68%) presented on weekends, outside regular working hours, and public holidays. A total of 52.5% of patients had taken prior antibiotics. Dental caries, smoking, mental health issues, and illicit drug use were featured strongly. The majority of patients (56.4%) underwent treatment under local anaesthesia. The total length of hospital stay was 271 days (mean 2.7, SD 1.6). Augmentin was the most prescribed antibiotic. Complications were reported in 8.8% of the patients, primarily due to airway compromise. Dental infections leading to hospitalisations continue to be a burden on the healthcare system. A notable finding was that the presentations were primarily on weekends, outside regular working hours, and public holidays, and the majority required dental interventions under local anaesthesia. The provision of on-call emergency dental services may reduce potentially preventable hospitalisations and the length of hospital stay.
