Surgical teams accidentally leave clamps, sponges and other tools inside about 1,500 patients nationwide each year.
The mistakes largely result not from surgeon tiredness, but from the stress arising from emergencies or complications(并发症) discovered on the operating table, the researchers reported.
The study found that emergency operations are nine times more likely to lead to such mistakes, and operating–room complications requiring a change in procedure are four times more likely.
It also happens more often to fat patients, simply because there is more room inside them to lose equipment, according to the study.
Two–thirds of the mistakes happened even though the equipment was counted before and after the procedure, in keeping with the standard practice.
Most lost objects were sponges, but also included were metal clamps and electrodes(电极). In two cases, 11–inch retractors (牵引器) metal strips were forgotten inside patients. In another operation, four sponges were left inside someone. When there is significant bleeding and a sponge is placed in a patient, it can sometimes look indistinguishable from the tissue around it.
The lost objects usually lay around the abdomen (腹腔) or hips but sometimes in the chest. They often caused tears or infections. Most patients needed additional surgery to remove the object. In other cases, patients even sensed nothing about the object, and it turned up in later surgery for other problems.
To prevent such mistakes from happening, Loyola University Medical Center is becoming one of the first hospitals in the country to use sponges outfitted with bar codes. The new system was brought to Loyola through the efforts of the hospital’s operating room nurses.
Another effective way is to X–ray patients after surgery to reduce the likelihood of objects being left inside patients.
1.In which of the following situations are objects most likely to be left inside a patient?
A．The nurses are counting the equipment and the patient is being X–rayed.
B．The surgeons are doing the last operation of the day, and everyone is exhausted.
C．unexpected happens and some changes must be made in the procedure.
D．A complex operation is going on according to the plan made by many experts.
2.Which of the following statements is NOT true?
A．Such mistakes happen more often to fat patients.
B．1,500 patients suffer from the mistake all over the world every year.
C．X–ray examination can help to find the lost objects.
D．The mistake largely results from stress rather than tiredness.
3.What can we infer from the passage?
A．Surgical teams aren’t to blame for the mistakes.
B．Some people never know there is something left inside their body.
C．Most mistakes happen because equipment isn’t counted after the procedure.
D．Only some small objects may be left inside the patients.
4.What is the best title for the passage?
A．Never Trust Anyone B．A Mistake in the Operating Room
C．Carelessness and Mistakes D．Tips for Patient Safety

Traditionally, robots have been hard, made of metal and other rigid material .But a team of scientists at Harvard University in the US has managed to build an entirely soft robot—one that draws inspiration from an octopus (章鱼).
Described in science journal Nature, the “Octobot” could pave the way for more effective autonomous robots that could be used in search, rescue and exploration. “The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots”, the study’s authors wrote.
Robots built for precise, repetitive movements in a controlled environment don’t do so well on rough terrains (地形) or in unpredictable conditions. And they aren’t especially safe around humans, because they’re made out of hard and heavy parts that could be potentially dangerous to their users.
So researchers have been working on building soft robots for decades. They’ve taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.
But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it’s still a grand challenge to construct flexible versions of essential parts, such as a source of power.
“Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration,” Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology Center for Micro-BioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.”
1.What’s the special feature of “Octobot”?
A.It’s very small. B.It’s made of metal.
C.It’s soft. D.It looks like an octopus.
2.What’s the shortcoming of traditional robots?
A.They’re hard to control. B.They can’t behave well all the time.
C.They can’t predict conditions. D.They’re too heavy to move.
3.Which of the following is wrong?
A.The original robots can work on rough land well.
B.The original robots may hurt people.
C.It’s tough to invent an absolutely soft robot.
D.The soft robots might improve the quality of human life.
4.One of the biggest challenges is to build Octobot’s ________.
A.silicone body B.complex structure
C.precise movements D.flexible power source
5.What’s the possible application of “Octobot”?
A.Medical research. B.Life rescue.
C.Machine operation. D.House cleaning.
