Wendy A Kaiser, MD in Chattanooga: Anesthesiologist for Hospital and Surgical Center Cases
Wendy A Kaiser, MD is a physician anesthesiologist providing anesthesia services for surgical, procedural, and hospital cases in the Chattanooga area. She administers general anesthesia, regional anesthesia, and monitored anesthesia care, taking responsibility for patient safety and pain management during procedures ranging from orthopedic surgery to cardiac cases.
What an anesthesiologist does and where Kaiser fits in Chattanooga's surgical landscape
An anesthesiologist is a physician who specializes in anesthesia, perioperative medicine, and pain management. Unlike nurse anesthetists (CRNAs) who administer anesthesia under physician supervision or independently depending on state law, anesthesiologists hold an MD or DO and complete a four-year residency in anesthesiology. In Tennessee, CRNAs may practice independently, but many surgical centers and hospitals employ or contract with anesthesiologists for oversight, complex cases, or concurrent patient management.
Kaiser operates as a contracted provider at surgical facilities and hospitals across Chattanooga and the surrounding region. Her primary role is pre-operative assessment, induction and maintenance of anesthesia during procedures, management of the patient's airway and vital systems, and post-operative recovery oversight. Chattanooga's main hospital systems, including Erlanger Health System and CHI Memorial, employ anesthesiologists on staff or contract with them for scheduled surgery, emergency procedures, and intensive care support. Kaiser's practice reflects the standard model: she works within these institutional settings rather than maintaining an independent office.
Anesthesia types Kaiser manages
Kaiser administers three main categories of anesthesia:
General anesthesia renders the patient unconscious and unable to feel pain, used for major surgery, complex procedures, and patients who cannot tolerate regional techniques. The anesthesiologist manages the airway, often using an endotracheal tube, and monitors breathing and circulation throughout.
Regional anesthesia (spinal, epidural, peripheral nerve blocks) numbs a specific area of the body while the patient remains awake or lightly sedated. This approach reduces systemic drug exposure and is common in orthopedic, obstetric, and lower-limb procedures.
Monitored anesthesia care (MAC), sometimes called twilight sedation, provides light sedation with local anesthesia for procedures like colonoscopy, cataract surgery, or minor orthopedic work. The patient is drowsy but responsive and breathing spontaneously.
The choice depends on the procedure type, patient medical history, and surgeon preference. Kaiser's background and credentials allow her to tailor anesthesia to the specific clinical need.
How to access Kaiser's services and what to expect
Patients do not schedule with Kaiser directly. Instead, when a patient schedules surgery or a procedure at a hospital or surgical center where Kaiser works, the facility's anesthesia department assigns her or another anesthesiologist to the case (or a CRNA, depending on the facility's staffing model and the procedure complexity). Prior to surgery, the patient will meet with the assigned anesthesiologist during pre-op evaluation, typically one to two days before the procedure but sometimes the morning of. During this consultation, the anesthesiologist reviews medical history, current medications, allergies, previous anesthesia experience, and any concerns, and explains the anesthesia plan.
Patients undergoing elective surgery should initiate contact with their surgeon's office, which will coordinate with the anesthesia department. For emergency procedures, anesthesia coverage is automatic at hospitals with surgical capacity.
Comparing anesthesiologist coverage across Chattanooga's surgical settings
Chattanooga's major hospitals maintain anesthesia departments with both physicians and CRNAs. Erlanger Health System and CHI Memorial both employ anesthesiologists and support CRNA teams. Some smaller or urgent surgery centers may rely more heavily on CRNAs with physician supervision at intervals rather than continuous presence.
For patients who prefer or require a physician anesthesiologist (for instance, those with complex medical histories, difficult airways, or who express a preference), facilities with dedicated anesthesia physician staffing offer more direct access. Kaiser's involvement at her contracted facilities means that patients undergoing surgery at those locations have the option of physician-led anesthesia management, which some insurance plans reimburse at a higher rate than CRNA-administered anesthesia (though reimbursement varies by plan).
The practical difference: a physician anesthesiologist monitors multiple patients in some settings but is immediately available; a CRNA may have a single patient under close attention with a physician anesthesiologist available for consultation. For routine procedures in low-risk patients, outcomes are comparable. For high-risk or complex cases, physician anesthesiologists are often preferred.
Who benefits from working with an anesthesiologist like Kaiser
Patients with complex medical histories (cardiac disease, difficult-to-manage diabetes, sleep apnea, previous anesthesia complications) benefit from a physician anesthesiologist's training in managing multiple physiological systems. Older adults, obese patients, or those on multiple medications also represent cases where anesthesiologist involvement improves safety margins.
Patients undergoing minimally invasive procedures in healthy status may not require physician anesthesiologist involvement; CRNA care under supervision is standard and safe in many surgical centers.
Hours and logistics
Kaiser's schedule follows the operating room and surgical facility calendar at her contracted locations. Elective surgery scheduling is available during standard business hours at most facilities; emergency surgical capacity is 24/7 at major hospitals. No walk-in anesthesia consultations occur; all contact flows through the surgeon's office or the hospital's pre-op department. Parking is available at all major Chattanooga hospitals.
Kaiser's credentials as a physician anesthesiologist and her presence at accredited surgical facilities make her a reliable resource for patients who need anesthesia for scheduled or emergency procedures in the Chattanooga region.
