“Every case is an opportunity to protect someone else’s family from tragedy”
Anesthesia requires precise control over your consciousness and vital functions, leaving little room for error at any stage of your procedure. Knowing your providers’ responsibilities helps you determine whether negligence—not unavoidable complications—caused your injuries.
Because anesthesia involves temporarily controlling your consciousness and vital functions, the margin for error remains dangerously slim throughout every phase of your procedure, from pre-operative assessment through post-anesthesia recovery. Your anesthesia team must evaluate your medical history, select appropriate medications, monitor your responses continuously, and manage your recovery—any failure along this chain can cause catastrophic harm that proper care would have prevented.
In Missouri hospitals, anesthesiologists and Certified Registered Nurse Anesthetists (CRNA’s) share responsibility for your safety, with CRNA’s administering anesthesia in approximately 65% of all procedures according to the American Association of Nurse Anesthetists (AANA, 2023). Federal regulations under 42 CFR § 482.52 require comprehensive pre-operative assessments to identify risk factors like drug allergies, heart conditions, or genetic predispositions to complications, and Missouri has not opted out of the federal requirement that CRNA’s work under physician supervision.
Your providers must also obtain informed consent by explaining the specific risks of your anesthesia plan—not just having you sign a generic form without meaningful discussion of what could go wrong. When providers skip these critical steps or fail to adjust their approach based on your unique medical needs, they violate both professional standards and Missouri law. These violations transform routine procedures into life-threatening emergencies, creating legal accountability for the harm that results.
Our greatest results have been the relationships we’ve forged with clients we’ve helped and the lives they’ve achieved after horrific accidents with the settlements our work brought about.
Every case is different and handled differently, but we are proud of what we have accomplished on behalf of previous clients. From multi billion dollar mass tort settlements to individual personal injury verdicts, we fight for every penny of compensation our clients deserve.
Past results do not guarantee future outcomes; every case is different.
Although modern monitoring equipment and protocols have improved anesthesia safety dramatically over the past several decades, human errors continue causing preventable injuries throughout St. Louis medical facilities. These mistakes often stem from rushed pre-operative evaluations, poor communication between surgical teams, and failure to follow established safety protocols, and understanding how these errors occur helps identify whether negligence played a role in your complications. The consequences range from temporary discomfort to permanent disability or death.
Dosage calculation errors remain among the most dangerous mistakes, particularly when providers fail to account for your weight, age, existing medications, or medical conditions that affect drug metabolism. While computers now assist with many calculations, anesthesiologists must still verify these recommendations against your specific circumstances—a step too often skipped in busy operating rooms where time pressures override safety protocols.
Intubation injuries represent another common source of harm, occurring when providers damage your teeth, throat, or vocal cords while placing breathing tubes, or worse, when they fail to recognize that the tube entered your esophagus instead of your windpipe, depriving your brain of oxygen.
Equipment malfunctions, though less common than human error, can prove equally devastating when anesthesia machines deliver incorrect gas mixtures or monitoring devices fail to alert staff to dropping oxygen levels.
According to data published in Anesthesiology Journal (2021), post-operative monitoring failures account for 24% of anesthesia-related injuries, often occurring when understaffed recovery units miss signs of respiratory depression or delayed emergence from anesthesia.
Medication errors—administering the wrong drug, miscalculating dosages, or failing to recognize dangerous drug interactions—continue to harm patients despite computerized safeguards designed to prevent such mistakes.
Perhaps no anesthesia complication causes more psychological trauma than awareness—remaining conscious but paralyzed while surgeons operate on your body. This nightmare scenario affects 1-2 patients per 1,000 general anesthesia cases according to the American Society of Anesthesiologists (ASA, 2022), often resulting from inadequate sedation combined with paralytic drugs that prevent you from alerting anyone to your consciousness, and victims describe feeling every incision, hearing surgical conversations, and experiencing overwhelming panic while unable to move or speak. The psychological aftermath of anesthesia awareness frequently includes post-traumatic stress disorder, severe anxiety about medical care, nightmares, and depression that can persist for years without proper treatment. Modern brain monitoring technology like bispectral index monitoring can prevent most awareness cases, yet many facilities fail to use these tools consistently or train staff to recognize warning signs that a patient may be regaining consciousness.
Malignant hyperthermia, though rare, demonstrates how failure to review family medical history can trigger life-threatening crises during routine procedures. This genetic condition causes certain anesthesia drugs to trigger massive muscle contractions, soaring body temperature, and organ failure within minutes, and proper screening identifies at-risk patients through family history of anesthesia complications or unexplained deaths during surgery, allowing providers to use alternative medications and keep emergency treatment readily available. Missouri law requires hospitals to maintain adequate supplies of dantrolene, the only effective treatment for malignant hyperthermia, and train staff in rapid response protocols. When facilities lack these preparations or providers miss obvious warning signs in your medical history, their negligence transforms a manageable risk into a preventable tragedy that may result in permanent disability or death.
Determining liability for anesthesia injuries requires understanding the complex relationships between medical providers, hospitals, and equipment manufacturers involved in your care. Unlike general surgical errors where one surgeon may bear primary responsibility, anesthesia cases often involve multiple defendants whose overlapping duties created opportunities for harm, and this complexity demands thorough investigation to identify all parties whose negligence contributed to your injuries. Each defendant may share responsibility in proportion to their role in causing your harm.
Because Missouri follows pure comparative fault principles under case law, multiple defendants may share responsibility for your damages in proportion to their contribution to your injuries, though they collectively cannot exceed the state’s non-economic damage caps of $473,444 for non-catastrophic injuries or $828,529 for catastrophic injuries according to the Missouri Department of Insurance (2025).
The injuries resulting from anesthesia errors often extend far beyond the immediate surgical period, creating cascading health problems that affect every aspect of your life.
Nerve damage from improper positioning during lengthy procedures can cause permanent numbness, weakness, or chronic pain that limits your ability to work or enjoy daily activities, and while providers should reposition patients regularly and pad pressure points, rushed surgical schedules and inadequate staffing often lead to hours of compression that destroys nerve function. These injuries may qualify as catastrophic under Missouri law.
Aspiration pneumonia occurs when anesthesia suppresses your protective reflexes, allowing stomach contents to enter your lungs and trigger severe infections that may require extended hospitalization or cause permanent lung damage.
Cardiovascular complications from anesthesia errors include heart attacks, strokes, and dangerous arrhythmias that can leave you with permanent disabilities or cognitive impairment, and elderly patients face particular risk of postoperative cognitive dysfunction, where anesthesia triggers lasting confusion, memory problems, and accelerated dementia that robs them of their independence.
Dental injuries from intubation may seem minor compared to other complications, yet broken teeth, jaw damage, or temporomandibular joint dysfunction can require extensive reconstruction and cause chronic pain.
The most severe outcome—death from anesthesia complications—occurs in approximately 1.1 cases per million population annually according to a Columbia University study analyzing 1999-2005 data (Li et al., Anesthesiology, 2009), though this historical data likely underestimates current risks given the aging population and increasing surgical complexity. When anesthesia errors cause death, surviving family members may be entitled to pursue wrongful death claims under Missouri law (RSMo § 537.080).
The injuries resulting from anesthesia errors often extend far beyond the immediate surgical period, creating cascading health problems that affect every aspect of your life.
Anesthesia malpractice cases demand specialized evidence that goes beyond typical medical negligence claims because the technical nature of anesthesia administration requires expert interpretation of complex medical records and monitoring data.
The anesthesia record, a minute-by-minute documentation of drugs administered, vital signs, and interventions, often provides crucial evidence of deviations from accepted standards, yet these records require expert analysis to identify subtle patterns indicating negligence, such as inadequate responses to blood pressure changes or delays in recognizing complications that a competent provider would have addressed immediately. The devil is in these details.
American Society of Anesthesiologists monitoring standards serve as baseline requirements that Missouri courts recognize when evaluating whether providers met their duty of care. These standards mandate continuous monitoring of oxygenation, ventilation, circulation, and temperature throughout procedures, with specific documentation requirements that create a paper trail of compliance or negligence, and violations of these standards may establish the breach of duty element of your malpractice claim.
Expert testimony from practicing anesthesiologists becomes essential to explain how violations of these standards caused your specific injuries, particularly when providers claim complications were unavoidable despite their errors.
Pre-operative assessment documentation proves especially critical in cases involving allergic reactions, drug interactions, or complications related to underlying medical conditions. Under Missouri law (RSMo § 538.225, effective 2020), your attorney must file an affidavit from a qualified healthcare provider within 90 days of filing your lawsuit, stating that your anesthesia provider breached the standard of care and caused your injuries, and this requirement makes early case evaluation and expert retention crucial for preserving your claim.
Your right to compensation may include both economic damages like medical expenses and lost wages, which remain uncapped under Missouri law, and non-economic damages for pain and suffering, which face statutory limits under RSMo § 538.210 but still provide meaningful recovery for your ordeal. Understanding these rights empowers you to make informed decisions about pursuing accountability for the harm you’ve suffered.
Economic damages include medical expenses and lost wages, which remain uncapped under Missouri law. This covers past and future medical bills, rehabilitation costs, lost income, and reduced earning capacity.
Non-economic damages for pain and suffering face statutory limits under RSMo § 538.210 but still provide meaningful recovery for your ordeal. Missouri caps non-economic damages at $473,444 for non-catastrophic injuries or $828,529 for catastrophic injuries according to the Missouri Department of Insurance (2025).

Understanding these rights empowers you to make informed decisions about pursuing accountability for the harm you’ve suffered.
Following an anesthesia injury, your immediate medical needs take priority, but protecting your legal rights requires prompt action even while you focus on recovery. Missouri law provides specific protections and remedies for medical malpractice victims, though strict deadlines mean delays can forever bar your claim, and because anesthesia complications may not fully manifest until days or weeks after surgery, documenting your symptoms and seeking appropriate follow-up care creates the medical evidence necessary to prove your case. Time is not on your side.
Obtaining complete medical records, including anesthesia records, monitoring strips, and nursing notes, should happen as soon as possible since some electronic data may be overwritten or archived after short periods.
Second opinions from independent physicians help establish that your complications resulted from substandard care rather than unavoidable risks, while also ensuring you receive appropriate treatment for ongoing problems that the original providers may be reluctant to acknowledge.
Missouri’s two-year statute of limitations for medical malpractice claims (RSMo § 516.105, effective August 28, 2018) begins running from the date of negligence, not when you discovered the malpractice, making early consultation with an attorney essential to preserve your rights.
While anesthesia has become significantly safer over recent decades, errors still occur more frequently than many patients realize. According to closed claims data, anesthesia-related complications account for approximately 3% of all surgical malpractice claims, though the severity of injuries tends to be higher than other surgical errors due to the potential for brain damage or death from oxygen deprivation, and the technical complexity of anesthesia administration means that even small deviations from accepted standards can have catastrophic consequences.
Both anesthesiologists (medical doctors) and CRNA’s (advanced practice nurses) can be held liable for malpractice when their negligence causes patient harm. In Missouri, CRNA’s must work under physician supervision according to federal regulations (42 CFR § 482.52), which means both the CRNA and supervising physician may share liability depending on the specific circumstances of the error. However, each provider remains responsible for their own negligent acts, and liability depends on who made the error and whether supervision was adequate, rather than simply on their professional title or credentials.
Yes, Missouri law recognizes psychological injuries from medical malpractice, including PTSD from anesthesia awareness. These claims require documentation of your psychological treatment and expert testimony linking your PTSD to the awareness episode, and compensation may include therapy costs, medication expenses, lost wages from inability to work, and non-economic damages for your emotional suffering. The trauma of experiencing surgery while conscious but paralyzed can be as debilitating as physical injuries, and Missouri courts recognize the legitimacy of these claims when properly documented and supported by expert testimony.
Missouri law requires filing within two years of the negligent act under RSMo § 516.105 (effective August 28, 2018), with limited exceptions for foreign objects or failure to inform of test results, and a ten-year absolute repose period bars any claims filed more than a decade after the occurrence regardless of when you discovered the injury. For detailed information about how these deadlines apply to your specific situation, consult with an attorney immediately since missing these deadlines can permanently bar your right to compensation.
Critical evidence includes complete anesthesia records, pre-operative assessments, consent forms, and post-operative monitoring data that document what happened during your procedure. Expert testimony from an anesthesiologist explaining how your provider deviated from accepted standards is also essential under Missouri’s affidavit of merit requirement (RSMo § 538.225), and this expert must practice in the same or similar specialty as the defendant to establish what a competent provider would have done differently in your situation.
