  1. Snake venom pretreatment to prevent surgical brain injury: The potential benefit of pretreatment with a variety of snake venoms in studies of surgical bleeding and post-surgery edema is promising. A number of projects are underway that involve department members and trainees. These projects are supported by an R01 NIH Grant (“Crotalus Snake Venom Preconditioning to Prevent Surgical Brain Injury”).
  2. Neurologic function after cardiac arrest: Interventions to improve neurologic outcome following cardiac arrest are being studied using a rat model of sudden cardiac arrest and resuscitation by researcher Dr. Lei Helen Huang. Working with other members of the Zhang lab this study of post-resuscitation interventions could provide treatments to improve outcome after cardiac arrest. This work is partially supported by a $25,000 grant from the Floyd S. Brauer Anesthesiology Research Endowment.
  3. Vasovagal syncope: The potential benefit provided by remote ischemic pre-conditioning for vasovagal syncope is being studied by a team led by Dr. Jiping Tang. This work is partially supported by a $75,000 Grant to Promote Translational and Collaborative Research (GCAT) from Loma Linda University School of Medicine.

Program Project Grant

Program Project Grant to establish the Center for Brain Hemorrhage Research: $7.7 million NIH award to the Zhang Neuroscience Laboratories. We anticipate a number of important findings to come from this Center. It is our hope that based on results from basic science projects we will be able to carry out translational research on interventions that show promise to improve outcomes after hemorrhagic stroke.

Pediatric Anesthesia Research

  1. Analgesia following surgery in children can be challenging. A team of LLU researchers investigated the impact of acetaminophen following cleft palate repair, finding a decrease in opioid use (Nour C, Ratsiu J, Singh N, Mason L, Ray A, Martin M, Hassanian M, Uhler J, Applegate II RL: Analgesic Effectiveness of Acetaminophen for Primary Cleft Palate Repair in Young Children: A Randomized Placebo Controlled Trial. Pediatric Anesthesia 2014; 24:574-58)
  2. Finding optimum methods to control pain in pediatric urologic surgery patients is being studied by a team led by Dr. Shannon Mulder: Preemptive analgesia in children using caudal epidural ropivacaine: A prospective, randomized, controlled study NCT01494272
  3. Premedication for pediatric patients is being studied by a group led by Dr. Amgad Hanna NCT02096900

Education research at LLU

  1. Decision making in critical events was reported on by a collaborative group that includes Dr. Marissa Vadi: Vadi MG, Patel N, Stiegler MP: Case Scenario: Local Anesthetic Systemic Toxicity after Combined Psoas Compartment–Sciatic Nerve Block Analysis of Decision Factors and Diagnostic Delay. Anesthesiology 2014; 120 (4):987-96
  2. Use of video interviews for resident selection is being studied by a group that includes Dr. Robert Martin, Dr. Marissa Vadi, Dr. Mathew Malkin, Dr. Gary Stier, Dr. John Lenart, Dr. Jason Gatling and Dr. Richard Applegate. An abstract based on preliminary analysis of this work has been submitted to the 2015 ASA Annual Meeting.

Perioperative Surgical Home

  1. Anesthesiology resident training in the Perioperative Surgical Home is being implemented and studied by a group led by Dr. Gary Stier and others. These results are being shared with the ASA PSH Collaborative. The Department’s perioperative care coordination project has targeted the care of patients undergoing major urologic surgery. Efforts to date focus on redesigning the entire perioperative episode of care for the patient, including the use of enhanced preoperative risk assessment and optimization tools, early discharge planning, improved patient education, intraoperative pain, fluid, and glucose management protocols, early ambulation, nutritional supplementation, postoperative medical management, and efficient transitional care planning. Preliminary data indicate reductions in hospital resource utilization and length of stay, along with greater overall patient satisfaction with the implementation of this model of care.
  2. Multimodal analgesia was associated with significantly less IV opioid administration and fewer adverse events following total knee arthroplasty in a study led by Dr. Mohamed Nour (ASA Annual Meeting 2014 Nour M, Applegate IIR, Herra D, Kuman G, Uhler J: Adverse Events Before and After the Implementation of a Multimodal Peri-Operative Pain Control Regimen for Total Knee Arthroplasty.
