Lesson of the patient's death to adopt robotic friendship surgery


Stephen Pettitt was a retired music teacher, 69, who had a heart problem.

The surgery that required 98% or 99% of success was successful. Here, he alleged that the surgeons who would performance of human activity.

But Pettitt's work was done by a robot and the patient died.

Pettitt, which was run in 2015 at Freeman's Hospital in Newcastle, England the first patient in the United Kingdom is Provide robotic cardiac attack.

And when an investigation of the causes of his death came to an end, "there is a danger that other deaths happen" with her; this approach.

The robotic cleansing program in England was suspended after the death of Stephen Pettitt.

In strategic surgery, mini-migratory ring tools will be used which can be installed in a number of small stones in the body.


In his opinion on the investigation, forensic doctor Karen Dilks said the death had been "a direct result of his work and his difficulties."

"Mr Pettitt died as a result of problems in work to cure mitral failure and, in part, due to the fact that the work was done with strategic help."

These problems included conversations among the surgeons operating the robot and dishes in surgeon training who did the procedure.

The judgment will raise important questions regarding their independence; increasingly from people on strategic management.

Net surgery was used with high levels of success since the early 2000s in thousands of hospitals around the world.

Robotic surgery is a kind of archaic surgery. That is, instead of working on the patient who performs large incisions, it is using micro-functional surgical instruments that can be inserted in a few small stones in the body.

What is done to put these medical instruments into robotic weapons, so The surgeon can make a sequence of motions with detail.

These systems have been used with high levels of success since the 2000s in thousands of hospitals around the world, especially for hysterectomies and prostate abolition.

In recent years some of the hospitals have begun to use it in a heart blade for valve repairs, such as the work of British patients subject to.

Surgeons trained

As Dr. Patrick Finlay, president of the British British Biological Engineering Association for the BBC, indicates the use of robots detected over the years to be safe, as long as it is The hands are handled on the training.

"It is necessary to send a device in a permissible mode to follow a string of hard steps, a number of rules and tests must be provided to ensure that the robot is safe," said the expert .

"It also needs the hands that are handled to be possible and for that they need training"

"The training is very simple, but it is possible to safely use one of these robots to train, not only with what you expect to happen but also with what is expected to happen, as well as training for the unique way you will meet "

He needs a lot of training and deployment of a surgeon before he can make a strategic surgery.

Professor Stephen Westaby, a surgeon of a friend at John Radcliffe's Hospital in Oxford, England, and one of the most familiar experts in the country, agrees.

"Robotic systems have been used safely in all types of surgery for many years," the expert tells the BBC.

"But in battle surgery there is a slight difference: This is made against the clock, because you are planning inside a & # 39; heart and working on the patient you must stop the heart and attach a lung-resistant to the patient to help with blood circulation. "

"In addition, a heart attack can be done with a solution called cardioplegia, to protect the heart."

But, as the scientist says, there is a long time for a while. As long as you are connected to a device, the maximum damage you can to; suffering the heart, and the longest time the blood is stopped, the hardest the heart is to begin.

"Then there are no benefits of using robots in a professional surgery due to the small reasons that need their operation and because of the next quick recovery, "said Professor Westaby.

"But the early revival depends on the reasons why I mentioned earlier," he says.

He wants to set up guidance that includes the use of directors-experts. Providing advice through surgery procedures.

Human error

The thing that has been the controversy in a British patient's case is that it has been revealed that they are not in this country Guidelines are set up for the use of robots in the operating room.

As the forensic inquiry said, a policy should be established which includes the use of expert managers. offer advice through the new procedures.

Her father, Karen Dilks, said in her research's conclusions that the training for new cures and interventions has "where there are no points of reference".

The investigation said that the surgeon was driving the Pettitt activity He did not have a personal training to use the robot.

He said that the patient would have survived if he had opened a heart surgery, and only 1% or 2% of chance would have to die.

But does this mean that robots should not be used in battle surgeons?

"No, no," said Professor Westaby. "There are many workers in this country and abroad who are experts in those jobs. To get there, much training is essential. "

"If we are going to introduce a new and innovative way to perform core jobs, we need to make a lot of use," said the expert.
