Abstract AIM: The aim of the study is the evaluation through transthoracic echocardiography of the haemodynamic modifications due to unilateral subarachnoid anaesthesia with bupivacaine 0.5% given for orthopaedic surgery. METHODS: In this prospective study, at the University Hospital Orthopedics surgical theater, 20 patients underwent orthopaedic surgery on the lower limbs. Unilateral spinal block was performed with hyperbaric bupivacaine 0.5%, 8 mg after a fluid challenge with saline solution 0.9%. Transthoracic echocardiography was performed and cardiac output was calculated from the left ventricular outflow tract (LVOT) with a recently validated technique. Cardiac output, stroke volume, ejection fraction, heart rate, mean arterial pressure were evaluated. These parameters were obtained before anaesthesia (t1), 5 minutes after anaesthesia (t2) and 16 minutes after anaesthesia (t3). RESULTS: Systolic, mean and diastolic arterial pressures after 5 min and 16 min from anaesthesia si...

Abstract

Abstract AIM: The aim of the study is the evaluation through transthoracic echocardiography of the haemodynamic modifications due to unilateral subarachnoid anaesthesia with bupivacaine 0.5% given for orthopaedic surgery. METHODS: In this prospective study, at the University Hospital Orthopedics surgical theater, 20 patients underwent orthopaedic surgery on the lower limbs. Unilateral spinal block was performed with hyperbaric bupivacaine 0.5%, 8 mg after a fluid challenge with saline solution 0.9%. Transthoracic echocardiography was performed and cardiac output was calculated from the left ventricular outflow tract (LVOT) with a recently validated technique. Cardiac output, stroke volume, ejection fraction, heart rate, mean arterial pressure were evaluated. These parameters were obtained before anaesthesia (t1), 5 minutes after anaesthesia (t2) and 16 minutes after anaesthesia (t3). RESULTS: Systolic, mean and diastolic arterial pressures after 5 min and 16 min from anaesthesia si...
