Anesthesia Injuries

This is a profession where even a small mistake can have devastating consequences for a patient. There’s a reason wrongful death is the leading cause of anesthesia-related medical malpractice claims.

Potential anesthesia injuries include:

  • Stroke
  • Heart attack
  • Paralysis
  • Coma
  • Brain injury
  • Spinal injury

Approximately 45% of all anesthesia-related medical malpractice cases are due to respiratory issues that result in brain damage or patient death. There are about 300 anesthesia-related deaths each year due to patients experiencing adverse side effects or overdosing.

Causes of Anesthesia Errors

Anesthesia errors can have serious physical and mental consequences for patients. If an anesthesiologist is inattentive, overlooks a medical issue, or ignores a warning sign, it can lead to patient endangerment.

Common errors made by anesthesiologists include:

  • Failing to properly administer the correct dosage
  • Utilizing defective equipment
  • Forgetting to educate patients about how to prepare for the surgery
  • Failing to properly place the oxygen tube
  • Neglecting to check a patient’s vital signs
  • Overlooking a patient’s medical history and allergies

St. Louis Medical Malpractice Attorneys for Emergency Room Errors

Our Contingency Fee Basis Means You Don’t Pay Until We Win Your Case

Of the 100 million patients admitted to emergency rooms each year, an estimated 5-10 million are the victims of devastating medical errors. The chaotic environment of an emergency room is due to overworked and overwhelmed doctors and nurses struggling to cycle through the number of gravely ill and injured patients. These emergency rooms are often understaffed due to deliberate hospital staffing decisions.

There is no excuse for emergency room medical errors, and hospitals must be held accountable for offering their patients poor and inattentive treatment. Call the medical malpractice lawyers at Buchanan, Williams & O’Brien, P.C. if you’ve been injured because of an emergency room error. To ensure you receive the legal counsel you deserve, we offer free consultations and work on a contingency fee basis.

Misdiagnosing Patients in the Emergency Room

Unfortunately, when an emergency room doctor fails to properly diagnose a patient, it can exacerbate the medical condition or even cause death. About 30% of all emergency room medical malpractice lawsuits are filed due to patient misdiagnosis.

Dangerous medical conditions that are often misdiagnosed include:

  • Appendicitis
  • Stroke
  • Heart attack
  • Brain aneurism
  • Pulmonary embolism
  • Internal bleeding

These are all dangerous medical conditions that can lead to a patient’s death.

How Emergency Room Errors Occur

Patients are admitted to emergency rooms when they require urgent medical care. What they usually experience is endless wait times in overcrowded waiting rooms. It’s not uncommon for a patient’s condition to decline while they wait for medical attention.

When patients are finally allowed to see their overworked doctors, they are quickly examined before being sent for testing. The medical staff in emergency rooms don’t have the time or resources to properly examine patients. In fact, many patients are improperly discharged before the doctor can even review their test results. These patients are sent away with medications and treatments that may aggravate their symptoms.

Common emergency room errors include:

  • Medication errors
  • Delayed test results
  • Surgical errors
  • Delayed treatments
  • Contaminated surgical tools

Failure to Diagnose Cancer

Discuss Your Legal Options with a St. Louis Personal Injury Lawyer Today

Cancer is a leading cause of death worldwide. The statistics are startling. According to the National Cancer Institute, one out of every two people will be diagnosed with some type of cancer during their lifetime.

The good news is that advances in modern medicine have made most forms of cancer treatable if caught soon enough. However, most cancers must be detected at an early stage. Many cancers are fast-growing, and the critical window for catching the early stages is often narrow. Early detection and diagnosis can mean the difference between life and death. The legal team at Buchanan, Williams & O’Brien may be able to help you pursue compensation if a medical professional’s failure to diagnose cancer caused you or your family undue suffering.

If your loved one suffered as a result of a medical practitioner’s failure to diagnose cancer, contact a St. Louis personal injury lawyer at Buchanan, Williams & O’Brien today for a free consultation.

Why the Detectable Goes Undetected

Unfortunately, doctors and medical providers sometimes fail to detect the early signs and symptoms of cancer. When this happens, families wonder how a trained medical professional could have missed the seemingly obvious signs of such a devastating diagnosis. The reality is that that delayed and missed cancer diagnoses happen far more often than you think.

Common reasons for delayed cancer diagnosis include:

  • Inattentive doctors and nurses
  • Understaffed and over-worked medical providers
  • Poorly trained doctors and nurses
  • Failure to deliver test results
  • Failure of the doctors to read test results
  • Failure of pathologist, radiologist, and other professionals who test for cancer to properly diagnosis

Commonly Overlooked Cancers

We handle cases involving all types of delayed and misdiagnosed cancers, including:

  • Colon and rectal cancer
  • Breast cancer
  • Skin cancer (melanomas)
  • Prostate cancer
  • Lung cancer
  • Kidney (renal) cancer

  • Bladder cancer
  • Cervical cancer
  • Uterine cancer

Hospital Negligence in St. Louis

Contact Our St. Louis Medical Malpractice Lawyers for Help

When you go to a hospital, you rightfully expect physicians and support staff to provide you with high-quality medical care. When treating patients, effective hospitals organize their staff to work as a team. While a physician is directly responsible for diagnosing and treating your illness or injury, the nurses and other hospital staff provide you with additional assistance and medical support. However, when the system breaks because organization is sacrificed, overworked and stressed medical staffers start making mistakes that are detrimental to patients.

Patient care is also dependent on hospitals providing functional, state-of-the-art technology and equipment. When a hospital provides faulty systems and equipment, additional mistakes may be made in the diagnosis and treatment of patients. Hospitals also need to be held responsible when patients are directly hurt or injured by this faulty equipment.

If you’re a victim of hospital negligence, it’s important to reach out to a medical malpractice lawyer. Contact Buchanan, Williams & O’Brien, P.C. if you’ve been injured or misdiagnosed due to hospital carelessness.

Call our medical malpractice lawyers at (314) 635-7606 to review your legal options.

File a Medical Malpractice Claim Against a Broken System

Patients deserve to be treated in clean, well-run hospitals. Unfortunately, in the rush to treat as many patients as possible, hospitals tend to sacrifice quality care. When the system that ensures quality care is broken, medical mistakes are made, and it’s the patients who suffer the consequences. This is considered hospital negligence.

Examples of hospital negligence include:

  • Doctors prescribing the wrong medication
  • Medical personnel providing outdated or broken equipment
  • Surgeons performing the wrong medical procedures
  • Medical staff overlooking the needs of their patients
  • Specialists failing to deliver timely test results

Staff Negligence

Patients depend on nurses and hospital orderlies for their daily care. While a doctor treats and investigates a patient’s symptoms, it’s the nurses and orderlies who provide personal care and assistance.

Examples of staff negligence include:

  • Dropping patients
  • Failing to provide necessary medical assistance
  • Drawing blood improperly
  • Not being careful when pushing patients in wheelchairs

Patient Falls in Hospitals

Failing to prevent patient falls is another example of hospital negligence. In fact, patient falls account for 84% of all inpatient accidents, and 30% of these falls result in serious patient injuries. Patient falls commonly occur when inattentive or understaffed medical personnel provide inadequate assistance and care to patients. For example, a patient can fall if a nurse administers medication but is ill-prepared to assist with the side-effects. Before starting treatments, medical staffers need to be prepared with adequate assistance devices and personnel strong enough to catch and lift a patient.

Medical costs can be 60% higher for patients who fall in hospitals because their injuries necessitate new treatments and longer hospital stays. You shouldn’t have to pay when the negligent care of a hospital causes you harm. Contact a medical malpractice lawyer to help fight the cost of medical bills related to your fall.

St. Louis Medication Error Attorneys

You depend on your medical care providers to prioritize your health and administer proper medications and treatments. However, it’s an unfortunate fact that medical care staffers are often unable to provide the level of personal attention and care every patient needs. Medication is a regular and important part of treatment, and when overworked and exhausted doctors make prescription errors, it’s the patients who suffer the consequences.

If you’re the victim of a medication error, contact Buchanan, Williams & O’Brien, P.C. to discuss your legal options.

Causes of Medication Errors

From the moment your prescription is written, there are many opportunities for an administrative or pharmaceutical mistake to occur. The Food and Drug Administration (FDA) estimates that nearly 7,000 deaths are caused by medication errors each year. Most medication errors go unnoticed, and the FDA claims they occur in as many as 1 in 5 patients.

Medication errors can be caused by:

  • Doctors prescribing the wrong medication
  • Doctors prescribing the wrong dosage
  • Miscommunication between doctors and pharmacists
  • Medical staffers failing to recognize drug allergies
  • Pharmacists dispensing the wrong medication
  • Medical personnel failing to properly label drugs

These errors can be easily avoided if medical personnel are attentive to proper precautions and procedures.

Misdiagnosis Lawyers in St. Louis

What Is Misdiagnosis/Delayed Diagnosis & How Does It Occur?

Misdiagnosis and delayed diagnosis are among the most common medical errors and result in many medical malpractice claims. Some sources say that as many as 40% of medical malpractice cases are from misdiagnosis or delay in diagnosis. Misdiagnosis and delayed diagnosis are a clear patient safety problem.

Misdiagnosis and delayed-diagnosis medical malpractice occur in many settings. For example, a doctor might misdiagnose a muscle strain in the chest or back when, in fact, the patient is having a heart attack. Delayed diagnosis is a related problem that occurs when the correct diagnosis is given but after a delay that harms the patient. Delayed diagnoses often occur when a doctor fails to order tests such as lab work, colonoscopies, or breast imaging studies in a timely manner.

Buchanan, Williams & O’Brien understands how frustrating and challenging this type of medical malpractice can be. We have experience addressing the specific issues that arise from these situations, and we want to help you recover the compensation you deserve.

If you believe misdiagnosis or delayed diagnosis caused you or a loved one harm, contact a St. Louis medical malpractice lawyer at our Brentwood firm today. Call (314) 862-6865 to request a free initial consultation.


Misdiagnoses are especially dangerous. In such cases, two bad things are often happening. First, the patient is not receiving the treatment needed for the medical problem they actually have. Second, the patient may be treated for an illness he or she does not have. The unnecessary treatment oftentimes causes injury to the patient.

For example, we worked on a case where a doctor failed to diagnose MALT lymphoma and instead diagnosed and treated the patient for a condition known as CVID. The patient was given a bone marrow transplant that actually made his MALT lymphoma worse, ultimately leading to his death.

Delayed Diagnosis

Delayed diagnosis may be the most common diagnostic error made by doctors. The consequences of these errors can be catastrophic, particularly when conditions like cancer are involved.

For example, we worked on a case recently where the patient had a pre-operative chest X-ray that showed a lung nodule. The nodule was reported to the ordering surgeon; however, the surgeon never told the patient or any of the patient’s treating doctors. Two years passed and the small nodule that was the size of a fingernail turned into an inoperable lung mass the size of a fist. The two-year delay in diagnosing the lung cancer was the difference between life and death.

Ensuring Accountability

The civil justice system plays an important part in improving the quality of patient care. The system holds doctors and hospitals accountable for their medical errors, and for good reason. Doctors and hospitals are held in high regard in our society, and they are paid handsomely for their expertise. When they fail to live up to this trust, they should be held accountable, just as the rest of us are accountable for our actions.

We help people who have been injured by misdiagnosis and delayed-diagnosis medical malpractice. Our St. Louis personal injury lawyers offer a free consultation so that you may discuss your concerns with an experienced attorney.

Surgical Error Attorneys in St. Louis

Seek Justice & File Your Medical Malpractice Claim Today

When it comes to acts of hospital negligence, a surgical error is one of the worst medical mistakes that can possibly be made. While a surgical error doesn’t necessarily indicate medical malpractice, it is still a preventable mistake that can lead to catastrophic consequences and even patient death.

Common examples of surgical errors include:

  • Harming muscles and ligaments
  • Leaving surgical equipment inside patients
  • Operating on the wrong patient
  • Accidentally damaging tissues and nerves
  • Operating on the wrong body parts

You have a right to seek compensation for injuries caused by surgical errors. Contact Buchanan, Williams & O’Brien, P.C. if you’re interested in filing a medical malpractice claim. We can help you seek compensation to cover your medical expenses and any loss of income you’ve experienced due to a surgical error.

Call our Brentwood medical malpractice attorneys at (314) 862-6865 if you’ve been harmed by a surgical error and believe your medical care provider has violated the medical standard of care.

Common Surgical Errors

Unfortunately, surgical errors are not uncommon, and the side effects are often devastating. The smallest mistake can cost unsuspecting patients their lives. Responsible surgical teams take extensive precautions to ensure patients receive the best possible care. However, most surgeons are exhausted and overworked because hospitals are often understaffed. The risk of a surgical error occurring rises exponentially when exhausted, overwhelmed, or incompetent surgeons staff a surgical team. When surgeons aren’t functioning at their best, the likelihood of insufficient planning and poor communication leads to even more opportunity for mistakes.

Consequences of surgical errors include, but are not limited to:

  • Death
  • Brain damage
  • Loss of limb
  • Infection
  • Organ damage
  • Chronic pain
