Chapter 53 Section 53
The operation was about to reach its final climax, and the replacement of artificial blood vessels was almost completed.Xi Ji was sweating profusely, and because of tension and fatigue, even standing was struggling.Even so, she concentrated and finished the final work.
"Excellent. I'll do the rest." Said Xi Yuan, and Yuan Gong looked at each other and nodded.
Xi Ji let out a relieved breath under the mask.But, they haven't gotten over all the hurdles yet.Although battery-operated lighting fixtures have been sent to the operating room, the brightness is almost no problem, but the battery life of various instruments is running out.
"The battery of the artificial heart-lung is running out, I'm going to switch to manual." Tamura's voice sounded in the operating room.
Xiyuan was concentrating on the work at hand, so Yuan Gong turned to look at Tamura and nodded slightly.
Tamura quickly fixed several pipes and began to turn the manual turntable on the operation panel counterclockwise.
"Please maintain the blood volume in the blood tank." Xiyuan said suddenly.Although his hands were busy, he still listened to the conversation between Tamura and the others.
"Understood." Tamura replied.
The manual dial of the artificial heart-lung device is actually quite heavy.Xi Ji had also operated it before when she was previewing the course, and she couldn't use the force after turning it for three minutes.At this moment, it must be rotated continuously at a speed of one hundred revolutions per minute, so Tamura cannot take care of other machines, and another clinical engineer surnamed Yoshioka is supporting him.But no matter how many people there are, it is useless to have no machines to use.
The room temperature continues to rise. This is because not only is there no air conditioning in the room, but also a large number of heat-generating light sources are used. One of the reasons is that there are more people than usual.
The nurse wiped Xi Yuan's sweat frequently, but this was still not enough to catch up with the speed of sweating. He blinked frequently, and the tiredness on his face became more and more obvious.To perform an operation that is inherently difficult under such circumstances will naturally consume a lot of physical and mental energy.
"Professor Xiyuan, is it alright?" Yuan Gong asked worriedly.
"I'm fine. What's the blood temperature now?"
"Twenty-nine degrees." Sayama replied immediately.
Until just now, the tubes of the blood circulation device continued to be cooled with coolant and ice.When using an artificial heart-lung device, blood must flow to the head at low pressure, and the supply of oxygen will naturally decrease.Body temperature is lowered to minimize oxygen consumption.However, it is no longer cool anymore.
"Tamura, is the heater not working?"
Regarding this question from Xiyuan, Tamura answered "no", sounding regretful.
The replacement of the artificial blood vessel is completed.The next step is to reduce the blood volume of the extracorporeal circulation in stages.It's just that the blood temperature was lowered to protect the brain before, but now it must be raised to close to body temperature.However, even if the cooled blood is sent directly back to the heart, the heart will not beat, hence the existence of instruments such as blood warmers, but without electricity, the machine is completely useless.
"I used ice cubes and antiseptic for cooling just now," Xiyuan said, "Now it has to be warmed up, so..."
"Come and ask the new star of the team." Yuan Gong looked at Xi Ji. "Okay, what should we do this time?"
"Let someone bring a warm bag in." Xi Ji said, "How about using a warm bag to increase the temperature of the heater from the outside?"
"Nuan Nuan Bao? Will the temperature rise?" Yuan Gong murmured.
"I don't know. But, as it is now, isn't it possible to do nothing? What should be considered now is a method that can be used without using electricity."
"I asked someone outside to prepare a warm pack." A nurse walked out of the operating room without waiting for Xiyuan's instructions.
