Study objectivesThe prophylactic perioperative correction of magnesium deficiency by infusion of magnesium sulphate to all patients presenting for thoracotomy or thoracolaparotomy for pneumonectomy, lobectomy or oesophagectomy will significantly reduce the incidence of supra-ventricular dysrhythmias post operatively.
Ethics approval(s)South Birmingham Research Ethics Committee. Date of approval: 04/05/2005 (ref: 05/Q2707/1)
Health condition(s) or problem(s) studiedSupra-ventricular dysrhythmias in patients following non-cardiac thoracic surgery
InterventionPatients are randomised into either the placebo or magnesium groups. Patients receive either placebo or 5 g magnesium sulphate infusion intra-operatively, day 1 and day 2 post-operatively. Continuous electrocardiogram (ECG) recording for 5 days will be commenced using a holter (non-invasive) recorder after induction of anaesthesia. ECG data will be analysed by a cardiac physiologist who is blinded from which treatment group the patient is in.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Magnesium sulphate
Primary outcome measureTo demonstrate a clinically and statistically significant reduction in the incidence of postoperative supra-ventricular dysrhythmias in the patient group who have received magnesium in comparison to the placebo group. It is aimed that patients have holter monitoring for 5 days post-operatively.
Secondary outcome measures1. Length of hospital stay
2. Thirty-day mortality
