Litigating Surgical Errors and Sepsis Misdiagnosis at Major Connecticut Hospitals

When an infection after surgery progresses to sepsis, a patient may face life-altering consequences that could have been avoided with competent care. While sepsis doesn’t automatically mean medical malpractice occurred, your family may have the right to take legal action if sepsis resulted from a preventable surgical error or a failure to properly respond to warning signs.

If you’re concerned that a healthcare provider’s violation of the standard of care contributed to post-surgical sepsis, our legal team at Kennedy, Johnson, Schwab & Roberge, P.C. can help you investigate what happened. Our Connecticut sepsis malpractice lawyers have been advocating for people harmed by negligence for over 35 years, and we’re ready to put that experience to work for you. If the evidence shows that preventable care failures contributed to your condition, we can pursue fair compensation on your behalf.

What Is Sepsis and Why Is Early Diagnosis So Important?

Sepsis is an extreme, life-threatening response to an infection. It occurs when the body’s immune system becomes dysregulated and turns on itself. This can progress to organ damage or even septic shock, which involves dangerously low blood pressure.

People experiencing sepsis often show warning signs before their health rapidly deteriorates. These symptoms may include:

  • Extreme pain or discomfort
  • Clammy or sweaty skin
  • Fever
  • Shivering or feeling very cold
  • High heart rate
  • Weak pulse
  • Shortness of breath or fast, shallow breathing
  • Confusion or disorientation
  • Lightheadedness
  • Increased symptoms of the underlying infection, such as painful urination or a worsening cough

After surgery, some of these symptoms may initially resemble expected recovery-related discomfort. However, medical professionals must still evaluate warning signs and determine whether an infection is developing. When providers dismiss these symptoms, a manageable postoperative infection can progress to severe sepsis that leads to permanent injuries or even death.

Surgical Errors That Can Lead to Sepsis

Preventable and common surgical errors can cause or worsen infections that ultimately trigger sepsis. Examples include:

  • Improper sterilization technique: Failing to properly clean the surgical site or sterilize instruments can introduce harmful microorganisms into the patient’s body during surgery.
  • Retained surgical items: When a surgeon leaves sponges, gauze, needles, clamps, or hardware in the patient’s body, the site can become a breeding ground for bacteria.
  • Delayed recognition of postoperative infection: Overlooking symptoms can lead to a medical misdiagnosis and allow an otherwise treatable infection to worsen.
  • Failure to respond to complications: After providers suspect or diagnose an infection, delays in necessary treatment could allow sepsis to develop.

Understanding Post-Surgical Sepsis and Breach of the Standard of Care

Some cases of sepsis after surgery involve medical malpractice. Under Connecticut law, malpractice occurs when a healthcare provider fails to meet the accepted standard of care and causes harm to a patient.

The standard of care is the level of treatment that a reasonably competent provider in the same field would advise under similar circumstances. In addition to errors made during surgery, breaches of the standard of care in a postoperative sepsis case may involve:

  • Failing to monitor the patient for signs of infection
  • Dismissing the patient’s symptoms or abnormal vital signs
  • Failing to order appropriate diagnostic tests
    Misinterpreting or failing to act on abnormal test results
  • Discharging the patient without addressing complications

Critical Legal Requirements Under Connecticut Malpractice Law

Two areas of Connecticut law can affect your ability to recover compensation for medical malpractice involving sepsis after surgery: the certificate of merit requirements and the statute of limitations.

Before you file your surgical error lawsuit in Connecticut, your attorney must investigate the care you received and obtain a written opinion from a similar third-party healthcare provider. The provider must explain why the evidence appears to show medical negligence, and your attorney must file a copy of this opinion with the lawsuit.

You have two years from the date you discovered, or reasonably should have discovered, your injury to file a medical malpractice lawsuit in Connecticut, but you cannot file more than three years after the date of the medical error. If a loved one passed away because of medical malpractice, the executor of their estate has two years from the date of death—but no more than five years after the medical error—to file a wrongful death lawsuit.

Medical Malpractice Cases Involving Connecticut's Major Medical Centers

Post-surgical sepsis can occur at any medical facility, including Connecticut’s major hospitals:

  • Yale New Haven Hospital
  • Hartford Hospital
  • Saint Francis Hospital and Medical Center
  • Backus Hospital
  • Bridgeport Hospital
  • Middlesex Hospital
  • Stamford Hospital

These hospitals perform thousands of successful surgeries every year, but it takes only one preventable error for sepsis to develop. When that happens, it’s essential to have a proven team of Connecticut medical malpractice lawyers on your side.

With extensive experience representing people harmed by errors at many of these facilities, we know how to investigate the care you received and determine whether negligence contributed to your injuries.

Frequently Asked Questions About Surgical Errors and Sepsis Medical Malpractice in Connecticut

If you suspect medical negligence caused you or a loved one to develop sepsis after surgery, you likely have many questions. Here are our answers to a few common ones.

Can I File a Medical Malpractice Lawsuit if Sepsis Was Not Diagnosed After Surgery?

You may have grounds for a medical malpractice lawsuit if your provider failed to recognize signs that would have prompted a reasonably competent provider to consider a sepsis diagnosis. The delay must have also caused you preventable harm.

The standard of care is the level of care or skill that a reasonably competent provider would deliver under similar circumstances. The exact standard in a sepsis case depends on your specific situation, but it likely involves monitoring the patient, recognizing warning signs, ordering appropriate tests, or beginning treatment promptly.

Proving that a surgical error caused sepsis requires medical evidence showing that the error caused or worsened an infection that ultimately triggered sepsis. Relevant evidence may include surgical reports, vital signs, blood tests, imaging, treatment notes, and expert testimony.

You typically have two years from when you discovered or reasonably should have discovered your injury to file a medical malpractice lawsuit in Connecticut. In most cases, you cannot file later than three years after the medical error occurred.

If you believe medical negligence caused your loved one’s sepsis, contact our Connecticut sepsis malpractice lawyers as soon as possible. We can investigate the circumstances and guide you through your next steps.
