Anesthesiology standard-of-care expert
Expert class library · Medical malpractice · Either side
Reviews preoperative assessment, airway management, sedation, intraoperative monitoring and recovery care when a patient suffers hypoxic injury, a hypertensive or hypotensive event, awareness or a nerve injury under anesthesia. Admissibility turns mostly on specialty match: courts bar physicians from other fields who cannot show familiarity with what an anesthesiologist does, but allow witnesses from overlapping fields on the part of the care they share, and treat disputes over the facts an expert assumed as questions for the jury.

Questions this testimony turns on
- Is the expert an anesthesiologist, and if not, can they show the standards of the two specialties are similar for the care at issue?
- What do the anesthesia record and monitor data show, and does the opinion rest on the record or on a witness's account?
- Which phase of care is criticized: the preoperative workup, induction, maintenance, emergence or recovery?
- Did the anesthesiologist have the information needed to recognize the problem at the time, judged without hindsight?
- Is the opinion about the anesthesiologist's own decisions, or about the surgeon's or another provider's?
Methods
- Anesthesia record and vital sign trend review
- Preoperative evaluation and ASA classification review
- Airway management analysis
- Sedation depth and recovery assessment
- Comparison with anesthesia society standards for monitoring
How the testimony is attacked
- Wrong specialty. Defendants argue a witness from another field cannot judge an anesthesiologist. In Gibson v. Soin the Ohio Court of Appeals upheld barring a cardiologist from testifying against an anesthesiologist and a pain specialist about presurgical cardiac clearance, because he did not show familiarity with how those specialists review presurgical testing.
- Opinion built on disputed facts. Defendants attack experts who rely on a witness's account rather than the chart. In Patrick v. Center for Restorative Breast Surgery the Louisiana Fourth Circuit reversed the exclusion of an anesthesiologist who relied on an observer's report of sustained high blood pressure, holding the observer's credibility was for the jury.
- Overlapping field limited to its overlap. Courts often admit a witness from a related field for a narrow part of the care. In Wakefield v. Gutzman the Utah Court of Appeals upheld letting a general dentist licensed for moderate sedation testify about the recovery phase after deep sedation, within the limited area the defense identified.
- Hindsight and record gaps. Defendants stress that anesthesia records are charted in real time and that an adverse outcome alone does not show the monitoring or response fell below the standard.
- Causation outside anesthesiology. Opponents argue that an anesthesiologist may speak to the standard of care but not to causes such as vision loss or neurologic injury, which may need a specialist in that field.
What the public record shows
Courts have filed at least 82 opinions since 2015 that discuss this class of testimony and cite Daubert or Rule 702, as of October 4, 2026. Three that show how courts handle this class of testimony:
| Outcome | Case | Court | Year | Why |
|---|---|---|---|---|
| Excluded | Gibson v. Soin2022-Ohio-1113 | Ohio Ct. App. | 2022 | The Court of Appeals affirmed a directed verdict after the trial court held a cardiologist incompetent under the state's medical expert rule to testify against an anesthesiologist and a pain management specialist, because he did not show the standards of care in the specialties were similar or that he was familiar with how they review presurgical testing. |
| Exclusion reversed | Patrick v. Center for Restorative Breast Surgery, LLCNo. 2022-C-0550 | La. Ct. App. | 2022 | The Louisiana Fourth Circuit granted a writ and reversed the exclusion of the plaintiff's anesthesiology expert, holding that the trial court improperly weighed the credibility of the fact witness whose blood pressure observation the expert relied on, which is a question for the jury. |
| Admitted | Wakefield v. Gutzman2024 UT App 76 | Utah Ct. App. | 2024 | In a death during dental surgery under deep sedation, the Court of Appeals upheld admitting a general dentist licensed for moderate sedation to testify for the defense about the recovery phase and whether an aspirated gauze could have been recognized, and held his testimony rested on a sufficient basis. |

Most of these rulings come from state courts, which apply their own evidence rules: many follow Daubert, some still apply Frye, and a few exempt certain testimony from a reliability hearing altogether. Check which standard governs in your court before relying on a ruling.
In federal court: amended Rule 702
In federal court, since December 1, 2023, Rule 702 says expressly that the party offering an expert must show the court it is more likely than not that the testimony meets each requirement: that it rests on sufficient facts or data, uses reliable methods, and reflects a reliable application of those methods to the case. Questions about the basis of an opinion are no longer automatically matters of weight for the jury. For how the circuits have applied the amendment, see the Rule 702 tracker, which follows each court of appeals; for what that means for preparing or attacking this class of expert, see the guide on amended Rule 702.
