Introduction Patients with haematological malignancy admitted to intensive care have a high mortality. Adverse prognostic factors include the number of organ failures, invasive mechanical ventilation and previous bone marrow transplantation. Severityof-illness scores may underestimate the mortality of critically ill patients with haematological malignancy. This study investigates the relationship between admission characteristics and outcome in patients with haematological malignancies admitted to intensive care units (ICUs) in England, Wales and Northern Ireland, and assesses the performance of three severity-of-illness scores in this population.
Measuring stroke volume variation may be a useful way of guiding fluid therapy in ventilated patients with severe sepsis because it allows estimation of preload and prediction of cardiac index changes in response to fluid loading.
Amphetamine induced ischaemic colitis is an exceedingly rare presentation of amphetamine toxicity. The cases reported in the literature have described mild or transient disease. We present a fatal case of ischaemic colitis induced by amphetamine use in a 44-year-old woman who presented in extremis after a cardiac arrest en route to the emergency department. A short history of headache, abdominal pain, vomiting and agitation preceded her admission. Imaging revealed changes consistent with ischaemic colitis. Emergency laparotomy revealed widespread colonic necrosis necessitating a subtotal colectomy. Despite aggressive resuscitation and inotropic support from arrival, the patient deteriorated intraoperatively and died in the immediate postoperative period. Histology showed arterial type ischaemia/reperfusion injury of the area supplied by the superior mesenteric artery. The patient's serum amphetamine level was 0.52mg/l (peak therapeutic levels <0.2mg/l). The postmortem examination concluded that amphetamines were the likely cause of the vasospasm, leading to profound colonic ischaemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
