RT Journal Article SR Electronic T1 Subcutaneous magnesium in the advanced cancer setting JF BMJ Supportive & Palliative Care JO BMJ Support Palliat Care FD British Medical Journal Publishing Group SP 191 OP 193 DO 10.1136/bmjspcare-2017-001360 VO 8 IS 2 A1 Stephen J Fenning A1 Steinunn R Boyce A1 Paul Wilson A1 Fran Stretton YR 2018 UL http://spcare.bmj.com/content/8/2/191.abstract AB Hypomagnesaemia can arise from a variety of causes but is particularly prevalent in cancer populations. This case report describes a patient with recurrent symptomatic hypomagnesaemia, on the background of advanced ovarian cancer and a high-output ileostomy, who was successfully managed on a daily continuous subcutaneous infusion of magnesium via a syringe pump. There is limited published information on the subcutaneous administration of magnesium and, to our knowledge, this is the first case to report its routine delivery over 24 hours in a syringe pump. This novel but effective approach for administering magnesium can be delivered in the community and can, therefore, prevent repeated hospital admissions for patients with recurrent symptomatic hypomagnesaemia who would otherwise need intravenous replacement.
