Stephanie Sorrell provides a case-based approach to calcium, sodium and potassium disorders before answering live questions from the audience. This 1.5-hour webinar is from a Regions Now event brought to you by our West Midlands region. Regions Now events comprise an introductory lecture with supporting content available one week before a live lecture. This is followed by a one-week online discussion forum allowing participants to offer observations about the lessons learned and describe their own experience in handling cases. Regions Now sessions are free to BSAVA members and available for non-members to book - visit the Regions page of the BSAVA website for details of future Regions Now events. Recordings will be available for 3 years via the BSAVA Webinar Library.
