Clinical Research

Clinical Anesthesia Research with research team

Clinical research in the Department of Anesthesiology & Perioperative Care takes place in diverse patient populations with funding from the Department, public and private grants and industry.

Areas of Interests

Perioperative Process Improvement and Patient Outcomes

Through initiatives like the Perioperative Surgical Home (PSH), we are actively seeking to improve patient safety, outcomes and experience through the use of standardization of care pathways using the best available evidence-based approaches. The PSH effort is a collaborative project between anesthesiologists, surgeons, nursing, physical and occupational therapists, nutritionists and more. It has demonstrated a sustained reduction in both complications of surgery and shortened length of stay for patients in the hospital.

In addition to the PSH, our Department has active research ongoing that studies critical events and emergencies in the perioperative environment, post-surgical projects following patients after they leave the hospital (when 50% of surgical complications occur) and pre-operatively (when there is an opportunity to optimize patient status before surgery occurs). The ultimate goal is to improve patient outcomes and experience whenever surgery is needed and to ensure that we are consistently delivering the highest possible level of care to our patients.

Innovation in Clinical Anesthesiology

Investigators within the Department are leading both single-center and multi-centered studies to optimize patient care using hemodynamic monitoring, novel techniques and systems, and deeper analysis of existing data sets. Areas of interest include goal-directed fluid therapy, development of novel devices and monitoring through collaborations with UC Irvine R&D centers like the Beckman Laser Institute and through joint projects with Industry partners. In some cases these efforts have led to start-up companies and ultimately commercial devices based on technologies developed in the Department.

A prime example is the development of sophisticated computer-assisted fluid-management algorithms for helping anesthesiologists provide goal-directed fluid therapy in the operating room. After development under Dr. Joseph Rinehart and Dr. Maxime Cannesson and extensive bench-to-bedside testing, this technology was licensed out and is now the integral component of Edward Lifescience’s Assisted Fluid Management Technology. With multiple members of the department actively involved with UCI Applied Innovation, we hope to continue to contribute new ideas and new discoveries to the field.

Education and Simulation Research

Research in simulation and educational innovations look towards new ways of training our medical students, residents, faculty and nurses, to improve patient care, reduce the amount of time to knowledge acquisition and mastery difficult skills. Many of these activities take place both at the UC Irvine Medical Education Simulation Center and within the medical center itself.

Ongoing projects include in-situ team training simulations between surgical specialties and anesthesiology to improve performance in critical events, our innovative residency education curriculum and utilizing simulation to increase skill acquisition.

Point-of-Care Ultrasonography

Point-of-care (POC) ultrasonography is brought to the patient and performed by the provider in real time. This allows the clinician to interpret findings simultaneous with the patient’s current signs and symptoms. This comprehensive whole-body perioperative ultrasound exam have been abbreviated as the F.O.R.E.S.I.G.H.T. exam (Focused periOperative Risk Evaluation Sonography Involving Gastro-abdominal Hemodynamic and Transthoracic ultrasound).

The curriculum is designed to help the perioperative physician with their clinical decision making for:

  1. Assessment of volume status
  2. Assistance with vascular access
  3. Determination of mechanisms of hypotension
  4. Assessment of cardiopulmonary function
  5. Other issues relevant to the perioperative physician

This is an expanding area of research and quality improvement projects. Our current research in this area includes evaluating teaching straggles to help educate residents on POC ultrasound as well as evaluating the benefit of POC ultrasound for assessing patients in the perioperative setting.
