Remaining lesson by the death of a patient passing through robotic cardiac surgery

Stephen Patlet was a retired music teacher, 69, who had heart problems.

I had the chance to succeed in 98 or 99% of the necessary surgical operations. This, of course, believed that the surgeon who created the operation was human.

But Pettitt's operation was done by Robot and the patient died.

Petit, who was operating in Newcastle's Freeman Hospital in England, was in 2015 The first patient in the United Kingdom is undergoing routine pediatric cardiac surgery with pneumatic treatment.

And according to the diagnosis of the cause of his death, this type of procedure "is at risk of other deaths."

Robotic cardiac surgery program was suspended in England after Stephen Pettytt's death.

In robotic surgery, miniaturized surgical instruments are used which can be included in many small body inserts.


In the investigation order, forensic doctor Karen Delux suggested that death was "the direct result of the operation and its complications".

"Mr. Pattiite died due to confusion difficulties in the operation for Mr Wattvi disease treatment, and in part as part of operation with Robotic Assistance."

These complications include discussions in those surgeons who used to run a robot and Deficiencies in surgeon training The process that runs.

This verdict raises important questions about the increasing dependence of humans on robot surgery.

Robotic surgery has been used since 2000 in thousands of hospitals worldwide, with high success rates.

Robotic surgery is a type of at least aggressive surgery. That is, instead of being operated on a patient running large things, the minimum use of surgery equipment can be used in some small insulin of the body.

What to do in order to put these miniarized surgeons in Robotic arms Creation can be a series of movements with precision.

Since the beginning of the 2000s, these systems have been used with high success rates, especially for hysterectoms and prostate extraction, in thousands of hospitals around the world.

In recent years, some hospitals have started using it for card valve repair in cardiac surgery, such as the operation of the operation of a British patient.

Trained surgeons

British Association of Biomedical Engineering Chairman Dr. Patrick Finley told the BBC that the use of robots has been proved for years, as long as it is safe. The hand that controls it is trained.

The expert says, "In order to put a robot in a surgical procedure, there is a need to follow the series of hard work, so many rules and tests must be passed to ensure that the robot is safe."

"It's also a hand that controls it Stay there Able and for that They need to Training"

"Training is very easy, but not only with the expectations you are making because of being able to use one of these robots, but also training for what you have to do with the specific action, which is not expected to happen."

Before the robot surgery can be done, it requires a lot of training and practice in the surgeon.

Cardiac surgeon Stephen Westby, a cardiac surgeon at John Radcliffe Hospital in Oxford, and agreeing to one of the country's most experienced specialists.

Expert tells the BBC that "robotic systems have been used in all types of safety in the surgery for many years."

"But there is a small difference in cardiac surgery: This is done against the clock, Because conceiving inside the heart and working on the patient, you should stop the heart and the patient should be connected to the heart and lung machine to help blood circulation. "

"Additionally, cardiac arrest is done with the reconciliation of Cardiopia, to protect the heart."

But the expert says, this is all the time disadvantages. Because you are connected to the machine for a long time, the heart can be further damaged and blood circulation is blocked for a long time, it is more difficult to resume the heart more.

Professor Westby says, "The use of robotics in cardiac surgery is beneficial only by procedural ingredients and quick recovery."

"But that's a quick recovery based on all the factors I mentioned earlier," he adds.

It is said to establish guidelines that include the use of specialist doctors – supervisor who offers advice during the surgical procedure.

Human error

In the case of the death of a British patient, the person who died from the majority of the dispute has declared that they do not exist in this country Guides for using robots in the operating room

As forensic investigations suggest, the policy should be established, which includes the use of specialist doctors – supervisors – who advise during new procedures.

Coroner, Karen Deluxe in its research findings suggests that there is "absence of reference points" in training for new treatment and intervention.

The investigation indicates that the surgeon points out that Pettitt's operation His personal training was not to use the robot.

He added that it is possible that if the open-heart surgery had been done, the patient would have survived, giving him only 1% or 2% chance of death.

But does this mean that the robot is not used in cardiac surgery?

"No, not at all," says professor Wesby. "There are many allies in this country and abroad who are experts in this operation. But To get there, many training is essential. "

The expert says, "If we are going to present a new and innovative way to do cardiac surgery, then we need to practice a lot."
