Nos constatations suggèrent que l'OA par lunettes nasales est associée à un moindre risque de désaturation en oxygène au cours des intubations en urgence. Cependant, compte de tenu de l'hétérogénéité des études, d'autres essais de grande qualité sont nécessaires pour déterminer quels patients pourraient bénéficier de l'OA au cours des intubations d'urgence.

Osteomas are slow growing bone tumours and are often asymptomatic. Rarely, they can be present in the temporal bone—only few cases had been reported, with an incidence of 0.1–1%. We describe a case of an osteoma of the temporal bone (retromastoid) found in a 40 year old female, who presented with a slow growing swelling behind the right ear for 9 years. Diagnosis was made on non-contrast computed topography (CT) of the skull. Treatment is indicated in symptomatic cases or cosmetic reasons. Screening colonoscopy and genetic testing for familial adenomatous polyposis (FAP) and Gardner’s syndrome are advised.

that the obese synthetic manikin was equivocally realistic, in that the landmarks were equally difficult to palpate and because it simulated bleeding.Our study demonstrates that this novel 'obese neck' synthetic model reproduces many of the difficulties encountered when performing an eFONA in an obese patient: it performed in a similar fashion to an obese meat-modified model and was more challenging than a traditional 'slim neck' manikin, while avoiding the practical hygiene issues associated with using pork belly to modify manikins. Such synthetic manikins may be useful tools for improving eFONA training in the future.

Spontaneous retroperitoneal haemorrhage (SRH) is rare. It may present with abdominal or back pain with or without haemodynamic instability. Aggressive resuscitation while investigating the cause of bleeding and providing haemostasis are the standard of care. Subsequent close monitoring is necessary to identify early complications.This study reports three patients who presented to our institution within the last 5 years with SRH from a ruptured pancreaticoduodenal artery (PDA) aneurysm. Each patient had a unique presentation, complications and treatment demonstrating the variability and complexity of SRH. One patient presented with sudden abdominal pain and hypovolaemic shock, underwent angioembolisation and had an eventful recovery. Another patient presented similarly and was treated via angioembolisation but experienced gastric outlet obstruction and obstructive jaundice requiring surgical haematoma evacuation. Another patient had an incidental finding of haemoperitoneum during laparoscopic cholecystectomy that was subsequently diagnosed as SRH resulting from a PDA aneurysm rupture secondary to medial arcuate ligament syndrome.
