Precordial Doppler Monitoring
Venous Air Embolism During Neurosurgery
All neurosurgery procedures risk serious complications including developing venous air embolus. But, the sitting or semi-sitting/inclined position adopted in craniotomy, craniosynostosis repair or surgery of the posterior fossa represent a higher risk. Precordial Doppler may detect the presence of air bubbles in the right heart structures by placing the transducer over the anterior chest wall when the patient has been positioned.
The DWL EZ-Dop is a small, portable Doppler monitor providing both visual and audio signals of Doppler flow velocities. Air embolus can be detected to alert the anaesthetists and surgeons to the sound of air in the heart cavities aiding the patient management and any complications that may arise.
Features of the EZ-Dop with Precordial Probe:
- The probe is non-disposable minimising ongoing costs of service
- The flat probe holder is supplied with adhesive fixations for ease of application
- Up to 60 seconds of signal buffer storage enables reporting of events, including DICOM integration
- Visual display of Doppler velocity waveforms assists with optimal probe positioning
- PW Doppler enables depth positioning of sample volume for signal optimisation
- Compact in size and with roll-cart or standard rail clamp to minimise impact in the operating theatre environment
Additionally, the EZ-Dop can be configured for Transcranial Doppler (TCD) monitoring and can be used pre-operatively to detect the presence of a Patent Foramen Ovale (PFO) prior to surgery.
