Why Anesthesiologists Get Sued: The Difficult Airway, Dental Damage, and Why Payouts Are Climbing

By John Mahoney · June 2026 · 9 min read

Anesthesiology is the field that proved a specialty can engineer its own malpractice risk down — then watched the severity of what remained climb anyway. Routine pulse oximetry and capnography in the 1980s cut the catastrophic respiratory events that once defined the specialty, and claim volume fell sharply. But the claims that survive are concentrated, technical, and increasingly expensive. For a med-mal attorney, the anesthesia file splits into two worlds: a high-frequency, low-value tail of dental injuries, and a low-frequency, catastrophic tail of airway and anoxic-brain cases where the dollars actually live.

This guide walks through what the closed-claims data shows about why anesthesiologists get sued — how often, how severe, which events drive the claims, and how documentation and monitoring decide whether a case is winnable or defensible — for plaintiff and defense med-mal attorneys triaging an anesthesia file.

Always verify the controlling standard and the underlying anesthesia record before relying on any generalization.

The Frequency and Severity Reality

By claim frequency, anesthesiology is mid-pack. The Jena et al. analysis (NEJM 2011) put the annual risk of facing a malpractice claim at roughly 7.7% — close to the all-specialty average of about 7.4% — well below the high-frequency surgical fields and above the lowest-risk specialties. But frequency is the least interesting number in this specialty.

Severity is the story, and it is rising. Dental and tooth-damage claims are common but low-value, dragging the frequency-weighted average down. Strip those out, and reported mean indemnity climbed to roughly $420,000 in the 2013–2018 window (up around 12.5%), with a reported median near $200,000. Most tellingly, the share of indemnity payments exceeding $500,000 reportedly jumped from about 19% in 2009 to about 36% in 2018, driven by catastrophic anoxic-brain-injury and death claims; hospital operating-room claims also run far costlier than ambulatory-surgery-center claims. The lesson for valuation: anesthesia exposure is bimodal — a chipped tooth and a hypoxic brain injury are both "anesthesia claims," and nothing about the per-claim average tells you which one you are holding.

The Dominant Allegation Types

Unlike the cognitive specialties, anesthesiology is a procedural field, and its allegations track performance and management rather than diagnosis. In The Doctors Company data (2013–2018, excluding tooth damage), the allegation mix was:

• Improper management of a patient under anesthesia — roughly 32% of claims. This is the clinical-judgment bucket: monitoring failures, hemodynamic and therapy mismanagement, failure to respond to a deteriorating patient.
• Improper performance of an anesthesia procedure — roughly 27%. Intubation, line placement, and regional-block technique.
• Dental injury / tooth damage — the most frequent single injury at roughly 20% to 23% of all anesthesia claims, but low severity.
• Improper patient positioning (nerve injury, around 6%), improper management of the surgical patient (around 5%), and improper performance of treatment (around 3%).

The allegation prior for anesthesiology is technical performance and intraoperative management — not a missed diagnosis. The central question is whether the realized harm reflects a negligent deviation in technique or monitoring, or a recognized, disclosed risk that materialized despite reasonable care.

The "Cannot-Miss" Events That Drive the Claims

Anesthesiology's high-severity claims cluster around the airway and the moments when oxygen delivery fails. The data point to the same recurring events:

• Adverse respiratory events. Historically the single largest source of injury in the ASA Closed Claims Project: difficult or failed intubation, inadequate ventilation or oxygenation, esophageal intubation, and aspiration — the category monitoring was designed to catch, and the one that still produces the worst outcomes when it fails.
• The difficult airway — "can't intubate, can't ventilate." The catastrophic scenario leading to anoxic brain injury or death. The litigation question is almost always whether the airway was adequately assessed beforehand and the failure managed per a recognized rescue algorithm.
• Death and cardiac/respiratory arrest. Reported in roughly 23% and 19% of claims respectively — the high-severity outcomes that drive the dollars.
• Peripheral and central nerve injury (around 17%), including positioning-related and regional-block injury.
• Regional and neuraxial complications — neuraxial cardiac arrest, high or total spinal, epidural or spinal hematoma, and local-anesthetic systemic toxicity.
• Dental damage during laryngoscopy — highest frequency, lowest payout.
• Awareness under anesthesia / intraoperative recall, and medication or equipment/monitoring-related events.

An airway-related anoxic injury or death is the high-value flag in this specialty; a dental case is the low-value floor. The difference in expected value is enormous, and a screen should never treat them with the same severity weight.

The Contributing Factors That Decide Who Pays

Behind the airway catastrophe is a recognizable set of contributing factors — several of them documentation and communication failures that, as in every specialty, drive payment more than liability:

• Technical performance / known procedural risk. Cited in roughly 88% of "improper performance of an anesthesia procedure" claims. The defense distinction that matters: was this a recognized complication of a properly performed procedure, or a deviation in technique?
• Improper selection or management of therapy (clinical judgment) — cited in roughly 44% of "improper management under anesthesia" claims.
• Patient-assessment deficiencies. Inadequate preoperative history, physical, airway assessment, and comorbidity evaluation. Claimant patients reportedly averaged two or more comorbidities, and many had one that affected the outcome — which cuts both ways: it supports causation defenses but raises the bar for preoperative assessment.
• Patient-monitoring failures — vital-sign trends, oxygenation, and ventilation not tracked or not acted on.
• Inadequate documentation — reported in roughly 18% of procedure claims. A thin anesthesia record is a defensibility problem independent of whether the care was negligent.
• Communication gaps — anesthesia-to-surgeon and handoff failures, reported in roughly 7%.

The documentation point deserves emphasis because the anesthesia record is unusually contemporaneous and granular — a time-stamped narrative of vital signs and interventions. Complete, it is one of the strongest defense documents in medicine; with gaps at the critical minutes, those gaps become the plaintiff's case.

Strong Case vs. Weak Case in Anesthesiology

Both sides screen the same record for the same signals, and the factors separating a strong anesthesia case from a weak one are largely symmetrical.

What strengthens a plaintiff's case

• A catastrophic, oxygen-deprivation outcome — anoxic brain injury or death — rather than a positioning or dental injury.
• A documented difficult-airway risk that was not assessed preoperatively, or a failure managed outside a recognized rescue algorithm.
• A monitoring trend (falling oxygen saturation, rising end-tidal CO2 abnormality) visible in the record with a delayed or absent response.
• Gaps in the anesthesia record at the decisive minutes, or an absent/inadequate informed-consent discussion of the realized risk.

What strengthens the defense

• A complete, contemporaneous anesthesia record showing prompt recognition and a guideline-concordant response to the event.
• A documented preoperative airway and comorbidity assessment with a tailored plan.
• A realized complication that was a known, disclosed risk of a properly performed procedure — the recognized-complication defense.
• A causation argument: in a comorbid patient, whether the outcome would have occurred despite optimal anesthetic care.

Anesthesia cases often turn on causation as much as breach — the comorbidity burden of the typical claimant means the defense will frequently argue the bad outcome was not anesthesia-driven. A disciplined causation timeline separates a payable airway case from a sympathetic but non-causal one.

The Expert and Merit Questions Come Early

Because anesthesia claims turn on technical standard of care, the expert is central and the qualification fight starts at the pre-suit gate. The expert who signs the certificate of merit must typically be qualified to opine against an anesthesiologist, and the same specialty-match and reliability questions feed directly into a later motion to exclude. Screening for both at intake prevents the avoidable losses — the strong airway case dismissed on a defective merit filing, or the expert who clears the merit gate but cannot survive a reliability challenge on causation.

Bottom Line

Anesthesiology is a moderate-frequency specialty with a rising severity tail. Dental injuries drive the claim volume and the per-claim average down; the airway catastrophe — difficult intubation, failed ventilation, anoxic brain injury, death — drives the dollars, and the share of large payouts has been climbing. The dominant allegations are improper intraoperative management and improper procedure performance. The contemporaneous anesthesia record is the case: complete, it is a powerful defense; gapped at the critical minutes, it is the plaintiff's strongest exhibit.

For both sides, the work is the same: separate the catastrophic airway/anoxic case from the low-value dental tail, read the anesthesia record minute-by-minute for recognition and response, run the causation question hard against the patient's comorbidity burden, and confirm the expert match and merit filing early. The merits should decide the case — so verify every generalization against the actual record.
