In this chapter, we learn that Dr. Xie and Dr. Zhexiong performed a surgery together in Afghanistan two years ago, and that there has been a lot of fighting and explosions in the country recently. We learn that the probability of a bomb falling where we are is about 1 in 150,000. This means that it is very unlikely that a bomb will fall where they are. The doctor is all, "I'm a surgeon! I can do the surgery!" and the anesthesiologist turns to him and says, "turns gulp, there's one more condition!" The doctor explains that they need to open his abdomen to fix the blood vessels. If they don't have enough, they can check the blood types of the people they're about to perform the surgery on and let them give their blood. The anesthesiologist says that the blood pressure isn't high enough and that the wound is too deep. He tells the doctor to get the people ready to give blood. He explains that this is a very difficult case because only about 4% of people are eligible for laparotomy, a procedure to open a vein in the body, and the mortality rate for this procedure is about 59%. They need to save the doctor ASAP.
