Research summary
This study will investigate which non-invasive method of measuring jugular venous pressure (JVP) is most accurate: physical JVP examination or ultrasound. JVP is an estimate of right heart pressure. In current practice, physical JVP examination is used to assess patients with suspected or known heart disease. Recent research indicates the use of an ultrasound probe may more accurately and reliably measure JVP. Finding out which method is best will enable doctors to assess JVP using the most appropriate investigation. This will allow doctors to make a more informed decision as to what further tests and treatments are required. An ultrasound probe will be used to record JVP measurements. This device is routinely used in hospitals and is commercially available for the purpose of measuring JVP. Patients undergoing heart surgery will be eligible for this study. Identifying the jugular venous pulse during the physical examination is more easily done in these patients, making this subset of patients most appropriate. Patients must also have a central line inserted as part of their surgery. The central line will measure central venous pressure and is the gold standard method for measuring right heart pressure. This will allow both the physical JVP measurement and the ultrasound measurement to be compared with the gold standard, identifying which method is most accurate. The site for this study is Sheffield Teaching Hospital NHS Foundation Trust. The trial will last 8 months. During the patient’s pre-operative assessment, a physical examination of JVP and ultrasound recording of JVP will be taken. The central line will be switched on to measure central venous pressure. The anaesthetist will complete the pre-operative assessment before the patient enters theatre. No additional visits will be required by the patient. Both the additional investigations are non-invasive and therefore make this a very low risk trial.
