On the Autonomy of Anesthetist

Background

The Byrd Doctrine

In 1932, the North Carolina Supreme Court decided Byrd v. Marion General Hospital — a case that would govern the liability of every nurse in the state for the next nine decades. The court’s reasoning was straightforward for its era: physicians are solely responsible for diagnosis and treatment, and nurses are not supposed to be experts in its mechanics. A nurse’s duty was to obey and execute physician orders — nothing more.

Under Byrd, a nurse could only be held liable in two narrow circumstances: (1) the nurse acted entirely outside the presence and direction of a physician, or (2) the physician’s order was so obviously negligent that any reasonable person would anticipate substantial harm from executing it. Short of those two conditions, the physician absorbed all liability for what happened in the clinical encounter — including decisions the nurse actively participated in making.

In 1932, this made practical sense. Nurses had minimal formal training, no independent licensing infrastructure, and no recognized scope of specialized clinical practice. The physician was genuinely the sole expert in the room. By 2022, that world had ceased to exist — but the legal doctrine had not moved with it.

The Patient

Amaya Gullatte

3 y/o female. An emergency department visit in September 2010 for an upper respiratory infection revealed an incidental finding of tachycardia, prompting cardiology referral. Workup disclosed dilated cardiomyopathy — a condition in which the myocardium is pathologically enlarged and contractile function is globally impaired, reducing stroke volume and ejection fraction. Her cardiologist recommended a radiofrequency catheter ablation to address her dysrhythmia.

Admitted: Carolinas Medical Center, Charlotte-Mecklenburg  ·  Date: October 20, 2010  ·  Procedure: Cardiac ablation

The Anesthesia Team

The anesthesia team consisted of Dr. James Doyle, M.D. (anesthesiologist, independent practice) and CRNA Gus VanSoestbergen (hospital employee, member of the facility’s specialized pediatric cardiac team). Both providers independently reviewed Amaya’s case and arrived at the same conclusion: sevoflurane mask induction.

The plan: administer sevoflurane via facemask to achieve induction, then transition to IV maintenance once the airway was secured. Dr. Doyle held final prescriptive authority. VanSoestbergen concurred, advised, and co-administered.

The Pharmacological Question

Sevoflurane in a Compromised Pediatric Heart

Sevoflurane is a halogenated volatile anesthetic routinely used for inhalation induction in pediatric patients — it has a pleasant odor, low blood-gas solubility coefficient (rapid onset and offset), and is generally well tolerated. In a hemodynamically normal child, it is a reasonable choice.

In a patient with dilated cardiomyopathy, it is a different calculation. Volatile anesthetic agents — sevoflurane included — produce dose-dependent myocardial depression, reducing contractility via inhibition of L-type Ca²⁺ channels and uncoupling of excitation-contraction coupling. In a heart that is already globally hypocontractile with reduced ejection fraction, superimposing a volatile agent’s negative inotropic load can precipitate abrupt hemodynamic collapse.

• Sevoflurane (chosen): inhalation induction via mask. Provides smooth, cooperative induction in children. However, causes direct myocardial depression and systemic vasodilation — a dual insult to an already failing ventricle.
• Etomidate (plaintiff’s proposed alternative): IV induction agent with the most hemodynamically neutral profile of any intravenous anesthetic. Minimal effect on myocardial contractility or systemic vascular resistance. The standard of care consideration in patients with severely compromised cardiac function.

Shortly after sevoflurane administration, Amaya’s heart rate dropped precipitously. Despite resuscitation efforts including epinephrine and CPR performed by Dr. Doyle, approximately 13 minutes of cerebral anoxia elapsed before circulation was adequately restored. The result: permanent hypoxic-ischemic encephalopathy, spastic cerebral palsy, and profound global developmental delay requiring full-time care for life.

The Legal Shift

The Procedural History

The family sued Dr. Doyle, CRNA VanSoestbergen, the hospital, and two additional treating physicians. A first trial in 2016 ended with a hung jury on the claims against Doyle and VanSoestbergen; Dr. Doyle subsequently settled. In the second trial in 2018, plaintiffs sought to introduce expert testimony from a CRNA specialist, Dean Cary, who would have testified that VanSoestbergen breached the applicable professional standard of care by agreeing to sevoflurane mask induction in a child with dilated cardiomyopathy — and that etomidate IV induction would have been the appropriate alternative.

The trial court excluded that testimony entirely, citing Byrd via Daniels v. Durham County Hospital Corp. (2005): a nurse cannot be held liable for participating in the planning and selection of an anesthetic technique while under physician supervision. The jury returned a verdict for VanSoestbergen. The Court of Appeals affirmed unanimously, noting — pointedly — that it lacked authority to overrule a Supreme Court precedent no matter how outdated.

The Supreme Court’s Holding

On August 19, 2022, the North Carolina Supreme Court reversed in a 3-2 decision written by Justice Morgan. The majority’s core reasoning was direct: the nursing profession of 2022 bears no resemblance to the nursing profession of 1932. CRNAs are now authorized by statute and board regulation to independently select, implement, and manage general anesthesia — making autonomous clinical judgments that physicians in Byrd’s era could not have imagined delegating. With that authority comes accountability.

The court held that even when a registered nurse is discharging duties under physician supervision, the nurse may be held liable for negligence and medical malpractice if found to have breached the applicable professional standard of care. It remanded for a new trial in which VanSoestbergen’s expert testimony would be admissible.

The Dissent

Justice Barringer, joined by Chief Justice Newby, dissented on two grounds. First, they argued the majority created liability without causation — if the physician retains final prescriptive authority and makes the ultimate treatment decision, the CRNA’s collaborative input cannot be the proximate cause of harm. Second, they argued that expanding professional liability in this way is quintessentially a legislative function: the General Assembly had 90 years to update the law and chose not to. Three justices should not substitute their policy judgment for that of the legislature.

What It Means for Supervised Providers

The Supervision Model Is Not a Liability Shield

Connette is a CRNA case decided in North Carolina. But its logic extends to any supervised anesthesia provider whose scope of practice has outgrown the purely executory model that justified blanket liability shields in the first place. Anesthesiologist Assistants practice in a physician-supervised care team model — but CAAs are trained to formulate anesthetic plans, select agents, and make real-time intraoperative decisions. That clinical independence is precisely what makes the profession valuable. It is also precisely what Connette says creates an independent duty of care.

The practical takeaway is not that collaboration with a supervising anesthesiologist creates liability — it is that failing to apply professional judgment within that collaboration does. A CAA or CRNA who identifies a safer anesthetic strategy for a high-risk patient, says nothing, defers entirely, and watches a preventable adverse event unfold is not insulated by the presence of a supervising physician. The duty runs independently.

• Collaborative decision-making carries collaborative accountability. If you participate in building the anesthetic plan — agent selection, technique, dosing strategy — you are accountable for the quality of that participation.
• Supervision transfers authority, not responsibility. The supervising physician’s final prescriptive authority does not retroactively sanitize a supervised provider’s negligent clinical input. Both can be liable simultaneously.
• Specialized training implies specialized duty. The more advanced the provider’s training and recognized scope, the higher the floor of expected competence. VanSoestbergen was a member of a specialized pediatric cardiac team — that specialization was central to why the majority found a cognizable standard of care applied to him.
