Advancements in Rodent Surgical Monitoring

  1. 1. InsideScientific is an online educational environment designed for life science researchers. Our goal is to aid in the sharing and distribution of scientific information regarding innovative technologies, protocols, research tools and laboratory services.
  2. 2. Merry Lindsey, PhD Graham Sattler Rodent surgical monitoring advocate, applications specialist, and Product Manager for Indus biomedical solutions Director of the Jackson Center for Heart Research at The University of Mississippi, celebrated professor, and expert in murine models of myocardial infarction Corey Reynolds PhD Director of the Mouse Phenotyping Core Lab at Baylor College of Medicine, advanced murine model surgeon, IACUC and animal care expert
  3. 3. How do you currently document your surgery for method consistency? Lab Notebook Recording on Data Acquisition System Photos of Surgical Setup Strip Recording 0% 10% 20% 30% 40% 50% 60% 70% 80%
  4. 4. Surgical Monitoring Overview What can Surgical Monitoring do for Me? MouseMonitor S Capabilities Critical Surgical Monitoring Signals Integrated Surgical Monitoring Doesn’t Have to Be Hard
  5. 5. What Can Surgical Monitoring Do For Me? Increased Survival Rate Consistent Procedures Better Surgical Training Consistent Outcomes
  6. 6. Surgical Monitoring Essentials… Non-Invasive 6-Lead ECG Blood Oxygenation Monitoring Respiration Monitoring Responsive Heating Core Temperature Measurement
  7. 7. Critical Surgical Monitoring Signals Multiple physiologic signals must be monitored to effectively assess subject health Monitor… Heart Rate Core Temperature Blood Oxygenation Maintain… Safe Core Temperature
  8. 8. Signal Integration… …it doesn’t have to be hard ECG, Heart Rate & Respiration Rate from a single set of electrodes Perform Surgeries directly on Stainless Steel top Intuitive Touch Screen Controls Factory Presets Enable Out of Box Operation All Signals Captured Non-Invasively
  9. 9. Rodent Surgical Monitoring In Review Comprehensive monitoring offers greater consistency and confidence Consistent Interventions + Higher Survival Rate = Better Outcomes The MouseMonitor S is the only preclinical research device that measures every key vital sign in one device Click Here For More Information
  10. 10. How important do you view rodent surgical monitoring? Very Important Important Somewhat Important 0% 10% 20% 30% 40% 50% 60%
  11. 11. What does the MPC Offer? The Mouse Phenotyping Core is a comprehensive facility offering expertise in the following areas: Imaging Metabolic Assays Cardiovasuclar Assays Respiratory Assays Neuromuscular Assessment Surgical services
