Hyperbaric Oxygen Therapy: Effect On Wound Healing And Traumatic Brain Injuries, Sara L. Seuffert Oct 2019

Hyperbaric Oxygen Therapy: Effect On Wound Healing And Traumatic Brain Injuries, Sara L. Seuffert

Student Publications

Hyperbaric Oxygen Therapy is a new form of treatment being used to heal and help improve symptoms of traumatic brain injuries, external wounds, and strokes. HBOT helps to completely saturate hemoglobin with oxygen, which then allows for a larger capacity of oxygen to be delivered to the damaged tissues. Tissue wounds benefit from this HBOT because of the increase in oxygen supply to the damaged area, helping to combat hypoxia, which is preventing proper wound healing. The increase in oxygen allows for an increase in myofibroblast differentiation to allow the healing process to continue. HBOT has also proven to increase …

The Effect Of The Implementation Of A Quarterly Triad Tool In The Pain Clinic Setting On The Assessment And Mitigation Of Risks In Patients On Chronic Opioid Therapy, Caroline Asava

Evidence-Based Practice Project Reports

The concurrent use of opioids and benzodiazepines (BZDs poses a formidable challenge for clinicians who manage chronic pain. While the escalating use of opioid analgesics for the treatment of chronic pain and the concomitant rise in opioid-related abuse and misuse are widely recognized trends, the contribution of combination use of BZDs, alcohol, and/or other sedative agents to opioid-related morbidity and mortality is underappreciated, even when these agents are used appropriately. Patients with chronic pain who use opioid analgesics along with BZDs have a defined increase in rates of adverse events, overdose, and death, warranting close monitoring. To improve patient outcomes, …
