The lessons left by the death of a patient who operates the robotic surgery


Stephen Pettitt was a psychiatrist, 69, who had a heart problem.

The operation surgery I needed was 98 or 99% chance to be successful. This, for the acceptance of the surveys that would have been executed, were human.

But the operation was subjected to pettitis carried out by a robot and the patient died.

Pettitt, operated in 2015 at the Freeman Hospital in Newcastle, England, was the first patient in the UK under the pioneering treatment of heart-shaped robotic surgery.

And the study concluded 'the cause of his death, "there is a risk of other things that arise" with this kind of procedure.

The robotics surgery program in England was suspended after the death of Stephen Pettitt.

In a robotics operation, miniaturized surgical instruments used in various small units can be used in the body.


In the opinion of the investigator, the forensicologist Karen Dilks has indicated that death has "a direct consequence of 's operation and its complications."

"Mr Pettitt died of compensation in an operation to treat treatment of valvinsul, and partly because the surgery was carried out with robotic help."

These complications contain threads under the surveillance that operate the robot and Deficits in training of surveys the procedure was executed.

The government makes important inquiries about the increasing degree of human robustness.

Robotic surgery has already been used with high successes since the early 2000s in thousands of hospitals around the world.

Robotic surgery is a minimal invasive surgery. That is, instead of operating the police with large injections, miniaturized surgical instruments used in several small injections in the body.

What has been done to place these miniaturized surgical instruments in robots, so The surge can perform a series of movements with prestige.

These systems have been using high successes since the early 2000s in thousands of hospitals around the world, especially for hysterectomies and prostate extracers.

In recent years, some hospitals have started to use in cardiac cardiac rehabilitation surgery, such as the operation that was subjected to British patience.

Trained surgeons

As Dr. Patrick Finlay, President of the British Association for Biomedical Engineering, stated that the use of robots, over the years has proven to be very serious, as long as The hands that do it are trained.

"The setting of a robot in a surgical procedure requires a series of stringent measures, it is necessary to adapt different regulations and tests to ensure that the robot is so," says the expert.

"It also requires that hands handle it be competent and for that she needs training"

"The training is very simple, but one of these robots can safely use training not only with the things you expect, but also with what is not expected, besides training for the specific procedure that you are performing"

It requires a lot of training and practice of surveillance before it can perform robotic operations.

Professor Stephen Westaby, a hearty surgeon in the John Radcliffe Hospital in Oxford, England, and one of the most experienced specialists in the country.

"Robotic system is so much used in all surgeries," says the case BBC.

"But in cardiovascular surgery there is a minor difference: This is performed against the clock, to visualize the inner heart of the heart and to & # 39; To operate a patient, you must stop the heart and connect the patient to a heart-lung machine to help help with blood pressure. "

"In addition, there is a heart attack arrest with a card called cardiac defense, to protect the heart."

But as the expert says, everything has the disadvantage of time. Because the longer you are connected to a machine, the more damage can learn the heart, and the longer the blood circulation is interrupted, the harder it is to restore the heart.

"Then the use of robotics in cardiovascular surgery has only advantages due to the small units that are required by the procedure and due to the sublime rapid reminder," says Professor Westaby.

"But this quick harbor will depend on all the invoices I've previously called," he adds.

It aims to put in place those that include the use of expert physicians-supervisors who offer advice on surgical procedures.

Human error

What most controversies have caused in the case of # 39; The British patience that died was that they did not die in this country Guidelines for using robots in operation.

If indicated by the underlying research, a policy should be taken to determine the use of expert-doctor teachers – the advice offered to the new procedures.

The coroner, Karen Dilks, has indicated in his conclusions that his & quot; Exemption of reference points is in & # 39; training for new treatments and interventions.

The study indicated that the surgeon directed the pettitt operation He does not have a personal training to use the robot.

He added that it was likely that the patient had survived when he had undergone an open heart operation, which he had only 1% or 2% chance to die.

But does this mean that robots are not used in cardiac surgery?

"No, not all," says Professor Westaby. "There are many colleagues in this country and abroad who are experts in these operations. To get there is a lot of training needed. "

"If we have introduced a new and innovative way to perform hosting, we have to do a lot of practice," says the expert.
