Undergoing surgery requires placing an enormous amount of trust in your surgeon, anesthesiologist, nurses, and the rest of your medical team. While every surgical procedure carries some degree of risk, patients have the right to expect that their healthcare providers will follow accepted medical standards and take every reasonable precaution to ensure their safety.
Unfortunately, preventable surgical errors do occur. When a healthcare provider’s negligence causes avoidable harm before, during, or after surgery, it may constitute medical malpractice.
Here are some of the most common surgical errors that may indicate a medical malpractice claim.
Unintended Injuries During Surgery
Surgeons work near delicate organs, nerves, blood vessels, and tissues. While some complications are unavoidable, others result from carelessness or a failure to follow accepted surgical procedures.
Examples of preventable surgical injuries include:
- Damaging a nearby organ or blood vessel
- Severing or injuring a nerve
- Causing excessive bleeding due to surgical error
- Failing to recognize and repair an injury before completing the procedure
When these injuries could have been prevented through reasonable care, they may be evidence of medical negligence.
Wrong-Site, Wrong-Procedure, or Wrong-Patient Surgery
One of the most serious—and entirely preventable—medical errors occurs when a surgical team operates on the wrong body part, performs the wrong procedure, or operates on the wrong patient altogether.
Healthcare facilities follow strict protocols designed to prevent these mistakes, including patient verification, surgical “time-outs,” and site marking before surgery begins. When these safeguards are ignored or performed improperly, the consequences can be devastating.
These types of errors are often strong indicators of medical malpractice.
Anesthesia Errors
Anesthesia allows patients to undergo surgery safely and comfortably, but administering anesthesia requires careful monitoring before, during, and after a procedure.
Potential anesthesia errors include:
- Administering too much or too little anesthesia
- Failing to properly monitor the patient’s vital signs
- Not recognizing an allergic reaction or medication interaction
- Delayed response to complications during surgery
Anesthesia mistakes can lead to permanent brain damage, heart complications, stroke, or even death.
Leaving Surgical Instruments Inside the Patient
Surgical teams are required to carefully count all instruments, sponges, and other materials before and after every procedure. Despite these safeguards, foreign objects are occasionally left inside patients.
Retained surgical items can lead to:
- Serious infections
- Internal bleeding
- Severe pain
- Organ damage
- Additional surgeries to remove the object
Because these incidents are almost always preventable, they frequently serve as strong evidence of negligence.
Post-Surgical Infections Caused by Negligence
Not every infection following surgery is the result of malpractice. However, infections may occur when healthcare providers fail to maintain proper sterilization procedures or provide appropriate post-operative care.
Examples include:
- Failure to properly sterilize surgical instruments
- Poor infection-control practices
- Delayed diagnosis or treatment of an infection
- Failure to provide appropriate wound care instructions
When preventable infections result in additional medical treatment or long-term complications, they may give rise to a medical malpractice claim.
When Is a Surgical Complication Medical Malpractice?
It’s important to understand that not every poor surgical outcome is the result of negligence. Many procedures carry known risks, even when performed correctly.
However, when a healthcare provider fails to meet the accepted standard of care and that failure causes preventable injury, the patient may have grounds for a medical malpractice claim.
