Systemic lupus erythematosus and the obstetrical patient--implications for the anaesthetist

Systemic lupus erythematosus (SLE) is a multisystem, chronic inflammatory disease characterized by autoantibody production. The disease is most frequently found in women of childbearing age and therefore may co-exist with pregnancy. The clinical manifestations of the disease are variable and depend on the severity of damage to organ systems such as musculoskeletal, renal, haematological, neurological, cardiac, and respiratory. Many patients require drugs such as aspirin or prednisone. The pregnant patient may experience exacerbations of the disease, neonatal loss, and obstetrical complications such as pre-eclampsia. Patients with the Lupus Anticoagulant are at risk for an abnormal perinatal course. The anaesthetic management will depend on the patient's clinical status and the well-being of the fetus. The patient should be examined to determine the extent of end organ damage, current medications, and the health of the fetus. Laboratory investigations such as a coagulation screen and tests of renal function should be performed before anaesthetic intervention if time permits. A multidisciplinary approach to care of the patient and resources to manage complications are essential to optimize the outcome for both mother and newborn.
