Perioperative Medication Safety & Management Expert
The perioperative period—encompassing the time before, during, and immediately after surgery—presents unique pharmacological challenges. Patients often enter surgery with complex, pre-existing medication regimens that must be expertly managed alongside potent anesthetics and post-operative drugs. When adverse events occur, determining whether they stem from the patient’s underlying disease, surgical factors, or medication mismanagement requires highly specialized analysis.
Dr. James Sonner brings over three decades of clinical and academic experience to the evaluation of perioperative medication safety. As a leading physician-scientist and Professor Emeritus at UCSF, he provides comprehensive, objective expert witness services to legal professionals, healthcare organizations, and regulatory bodies nationwide.
Specialized Analysis of Surgical Drug Complications
A critical component of patient safety is the management of chronic medications—such as anticoagulants, antihypertensives, and antidepressants—during the surgical window. Dr. Sonner specializes in identifying deviations from the standard of care and analyzing complex physiological responses in the perioperative setting. His areas of review include:
- Pre-Operative Medication Management: Evaluating whether a patient’s existing medications were properly continued, paused, or adjusted prior to surgery (e.g., managing blood thinners to prevent hemorrhaging or thrombosis).
- Intraoperative Drug Interactions: Analyzing adverse reactions and toxicity resulting from the combination of a patient’s chronic medications and anesthetic agents administered during the procedure.
- Post-Operative Complications: Reviewing the safe administration of pain management therapeutics, including opioid dosing, respiratory monitoring, and the prevention of post-operative medication errors.
- Transitions of Care: Assessing medication reconciliation processes when patients are transferred between surgical suites, recovery rooms (PACU), and intensive care units.
Professional Deliverables
Whether evaluating an isolated adverse event or analyzing systemic hospital protocols, Dr. Sonner provides clear, actionable insights through:
Comprehensive Case Evaluation
Thorough review of patient charts, anesthesia records, and pharmacy logs.
Evidence-Based Reporting
Clear, authoritative written opinions grounded in current medical literature and pharmacological science.
Deposition & Trial Testimony
The ability to communicate intricate medical and pharmacological concepts with absolute clarity to judges, juries, both military and civilian, and non-medical professionals.
Unbiased Expertise for Complex Medical Cases
Dr. Sonner’s approach is rooted entirely in scientific evidence and established medical guidelines. Because he does not base his conclusions on the retaining party’s desired outcome, his opinions offer profound value to plaintiffs, defense counsel, and institutional risk managers alike. He meticulously reconstructs the clinical timeline to determine the exact role that pharmacological agents played in a patient’s outcome.
