Lessons that come from the death of patients suffering from heart-beating robots


Stephen Pettitt was a retired musician, 69, had a heart problem.

The surgery I needed was 98% or 99% successful. In this way, the surgeon's operations were human.

But the operation caused by Pettitt was made by a robot and the patient died.

Pettitt, who worked in Freeman Hospital in Newcastle, England, in 2015 The UK patient suffers from pioneering surgical heart palliative treatment.

And it concluded that due to death, "there is another risk of death with this type of procedure."

In robotic surgery, miniaturized surgical bodies are used to insert them into different cut into the body.


In the trial, Karen Dilks, a forensic doctor, has stated that death is a direct consequence of "operations and complications."

"Mr Pettitt died as a result of an operation to treat the mitral valve disease and, to a certain extent, the operation was carried out with robotic assistance."

These complications were discussed among the surgeons in the operation of the robot Loss of surgeon training He made the procedure.

The decision refers to important questions about the addiction of robotics to surgeons.

Surgical robot has been successful in thousands of hospitals around the world since the beginning of 2000.

Surgery robot surgery is minimally invasive. Therefore, patients with large incisions do not use miniaturized surgical operations because they are included in different cut into the body.

To do this, you need to put in place miniaturized robotic wardrobes The surgeon can accurately make a series of movements.

Systems have been successfully used in thousands of hospitals all over the world, including hysterectomies and prostate extraction.

In recent years, some hospitals have been using cardiovascular surgery to repair valves, such as the operation caused by the British patient.

Trained surgeons

Dr Patrick Finlay, President of the British Biomedical Engineering Association, said the BBC has proven its safety for many years, trained hands are trained.

"Roboting in the surgical procedure following a series of rigorous measures, must be followed by certain rules and tests to ensure that the robot is safe," says experts.

"It also manages hands There are competent and for that they need training".

"Training is very easy, but it allows one of these robots to be safely used, not just with what happens to you, as it is not expected, in addition to the preparation of specific procedures."

It requires a lot of practice to prepare and practice surgery before performing a robotic surgery.

Professor Stephen Westaby, John Radcliffe's Heart Surgeon at Oxford, England, is one of the most experienced specialists in the country.

"Robotic systems have been safely used in all surgeries for many years," says the BBC.

"But there is a small difference in heart surgeries: this is against the clock, to see the interior of the heart and to stop the patient's heart functioning and connect the patient's heart lung machine to facilitate blood circulation. "

"Additionally, heart arrhythmia carries out the cardioplegia solution to protect the heart."

But the expert says, all this is a disadvantage of time. When connected to a machine connected to a machine, because the heart can suffer more damage and the blood circulation is interrupted, the harder it is to restart the heart.

"Then, the use of cardiovascular robotic surgery is due to the small incisions required by the procedures due to rapid recovery suppository effects," says Westaby teacher.

"But fast recovery will depend on all the factors we have mentioned earlier," he added.

Human error

What has caused the British patient has caused the most talk of the patient in this country that they do not reveal. Instructions for the use of operator robots.

As regards the Court's investigation, it is necessary to establish a policy that includes the use of advisors and policy-makers advising new procedures.

Judge Karen Dilks, in her research, points out that "lack of reference points" in training and treatment for new interventions.

According to the study, the surgeon who directed the Pettitt operation He did not have personal training to use the robot.

It is possible that the patient survived if he had an open heart surgeon, only 1% or 2% of the dead.

But does this mean that robots should not use their hearts?

"No, no, no," says Westaby. "There are many colleagues in this country and abroad, who are experts in these operations, but To get there, there are many workouts. "

"If we present a new and innovative way of doing heart operations, we must do a lot of practice," says experts.
