Robotic cardiac surgery from the patient's death


Stephen Pettit was a 69-year-old retiree, a heart problematic teacher.

Surgery was a success, with 98 or 99% success. Surgical surgeons are considered to be human beings.

But Pettitt conducted a robotic operation and the patient died.

Pittyt, who was operated in Friman hospital in Newcastle, England in 2015 The first patient in the UK has been admitted to advanced cardiac robotic surgery.

In the investigation of the cause of his death, this procedure has "other death threats".

The robotic cardiac surgery program in England was canceled after Steven Pittt's death.

Robotic surgery uses smaller surgical instruments that can be slimmed into smaller pieces in the body.


According to the court decision, the forensic doctor Karen Dilks showed that the death was "a direct consequence of the operation and its complications."

"Mr. Pettit died of complications in the treatment of mitral valve diseases, and partly because the surgery was done by robotics."

These complications were discussed by surgeons who supervised the robot deficiencies in the training of surgeons he carried out the procedure.

This decision raises important questions about the increase in human dependence on robotic surgery.

Since the early 2000s, robotic surgery has been successful in thousands of hospitals in the world.

Robotic surgery is a form of less invasive surgery. That is, smaller surgical instruments are used instead of performing large images in the patient, which can be put into several small pieces in the body.

These miniature surgical instruments should be placed in robotic weapons A surgeon can perform exactly the same movement.

These systems have been very successful for thousands of hospitals in the world since 2000, especially for hysterectomy and prostatitis extraction.

In recent years, some hospitals have begun to be used for cardiac surgery, for example, in a British patient operation.

Trained surgeons

Dr. Patrick Finlay, President of the British Society of Biomedical Engineering, told BBC that the use of robots has been proven to be very secure for years. Handmade hands are taught.

"Robotic surgery requires a series of strict measures, and it is necessary to carry out a series of rules and tests to ensure that the robot is safe," said the expert.

"He also needs to hold hands to be competent and for that they are needed training«

"Training is very simple, but using one of these robots safely needs to be taught not only for the expected ones, but also for the unexpected ones, as well as learning the exact procedure you have performed"

Before he can do robotic surgery, he needs a surgeon's training and experience.

Cardiac surgeon Steven Westbee, of the John Radcliffe Hospital in Oxford, England, agrees with one of the most experienced specialists in the country.

"Robotics have been safely used for many years in all types of operations," said the expert.

"But there is a small difference in cardiac surgery: this is done against the clock, because in order to see the inner vision of the heart and work for the patient, stop the heart and add the patient to the heart-shaped device to help the circulation. "

It is also called cardioplasty to keep the heart and protect the heart.

But as the expert puts it, this is all the time of weakness. The longer you have been added to the car, the more heart can be damaged, the longer the circulation will be, the more difficult it will be to restart the heart.

"Then robots have the advantage of being used in cardiac surgery for small pieces and fast recovery," says Vestaby.

"But this fast recovery will depend on all the factors mentioned earlier," he adds.

In the surgical procedures, consultants are required to make recommendations that include the use of medical practitioners.

Man's mistake

It has been discovered that there is no such thing as the most controversial issue in the British patient instructions for using robots in the operating room.

As it is seen in the course of the investigation, it is necessary to establish a policy that includes the use of medical supervisors who advise on new procedures.

Investigator, Karen Dills, said in his research that there was no "reference point" in the training for new treatment and intervention.

During the investigation, he showed that he was a surgeon who was leading Peter's surgery He did not have his own exercise to use the robot.

He said he could survive if the patient suffered from open heart disease. It was only 1% or 2% of deaths.

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

Professor Westaby says, "No, not at all." "There are many partners in this country and abroad, and they are specialists in these operations. But it is More training is needed to achieve it. "

"If we plan to introduce a new and innovative method of cardiac surgery, then we have to implement a lot of practice," said the expert.
