The impact of pre-operative focused transthoracic echocardiography in emergency non-cardiac surgery patients with known or risk of cardiac disease

Anaesthesia, 05/03/2012

Canty DJ et al. – Pre–operative focused transthoracic echocardiography in patients admitted for emergency surgery and with known cardiac disease or suspected to be at risk of cardiac disease frequently alters diagnosis and management.

Methods

  • This prospective observational study investigated the effect of focused transthoracic echocardiography in 99 patients who had suspected cardiac disease or were ≥65years old, and were scheduled for emergency non-cardiac surgery.
  • The treating anaesthetist completed a diagnosis and management plan before and after transthoracic echocardiography, which was performed by an independent operator.
  • Clinical examination rated cardiac disease present in 75%; the remainder were asymptomatic.

Results

  • The cardiac diagnosis was changed in 67% and the management plan in 44% of patients after echocardiography.
  • Cardiac disease was identified by echocardiography in 64% of patients, which led to a step-up of treatment in 36% (4% delay for cardiology referral, 2% altered surgery, 4% intensive care and 26% intra-operative haemodynamic management changes).
  • Absence of cardiac disease in 36% resulted in a step-down of treatment in 8% (no referral 3%, intensive care 1% or haemodynamic treatment 4%).
