Uses of ultrasound in anaesthesia

Created: 9/10/2005
 
Imaging vessels for safe cannulation (SonoSite)
Locate pleural effusions and to guide taps
Locating vessels anterior to the trachea prior to tracheotomy
Guidance for nerve block procedures
Transoesophageal echo may be used perioperatively to aid fluid management, detect air embolism and monitor valvular function during cardiac surgery
 Oesophageal Doppler
There is research into the use of ultrasound to locate the epidural space 
 Transcranial Doppler ultrasonography


 Women's healthcare

Visualise the morphology of pelvic organs Identify fetal anomalies
Detect three-vessel umbilical cord
Determine fetal heart rate
Define hormonal status
Define the status of ovulation and identify pregnancy
Avoid unnecessary surgical diagnostic procedures
Assess and biopsy suspicious breast masses
Identify cause of abnormal bleeding
Assess amniotic fluid levels
Confirm fetal age and delivery date
Pulsed-wave (PW) Doppler provides quantitative analysis of fetal vessels, maternal vessels or umbilical cord

Cardiovascular

Clinically proven diagnostic quality comparable to large cart-based systems
Accurately assess intracardiac blood flow with continuous-wave (CW) and PW Doppler
High-resolution 2D-imaging for rapid assessment of cardiac structure and function
Literally possible to carry your ultrasound system anywhere -- from office to hospital, between satellite offices or to multiple locations for mobile services
Small size fits into cramped patient rooms or small office space
Ergonomic design
Vascular and paediatric imaging capabilities
Comprehensive cardiac and vascular calculation packages for quantitative evaluations

Surgery

Localise anatomical structures and pathology to guide biopsies and interventional procedures
Confirm location of pathology prior to incision and completion of procedure prior to closure
Monitor status and progress of interventions
Determine extent of pathology and anatomical involvement to guide excision
The patient can be re-scanned to answer clinical questions or guide procedures in surgery, in the recovery room or in a critical care setting
Identify free fluid in the abdomen or pericardia

Emergency medicine

Rapid triage and assessment of trauma (FAST)
Detection and assessment of abdominal aortic aneurysms
Visualisation of abdominal fluid collection
Evaluation of pericardial or pleural effusions and tamponade
Immediate assessment of pelvic pain and abnormal uterine bleeding
Fast, easy emergency obstetric examinations (intrauterine pregnancy, fetal viability)
Rapid evaluation of acute abdominal pain (kidney, cholelithiasis)

Radiology and general imaging

Rapid delivery of ultrasound to immobile patients
Identify and treat problems earlier with answers on the spot
Offers a portable solution for interventional procedures
Eliminates the transport of heavy cart-based ultrasound systems
