Chapter 1513 Extraction of Internal Organ Samples
"Understood, Teacher Zhang!" Xiao Lin quickly replied, picking up a sterile scalpel, tissue specimen bottle, and sterile pipette from the instrument tray and handing them to Zhang Lin. Zhang Lin took the instruments and gently extracted the sample, carefully cutting off a small piece of tissue from the damaged area of the spleen, placing it in the tissue specimen bottle, pouring in an appropriate amount of fixative, and sealing it. Then, using a sterile pipette, he extracted a small amount of splenic hemorrhage sample, placed it in a sterile test tube, and sealed it.
Xiaolin took the samples and quickly marked them: "Unidentified male corpse, spleen injury area tissue sample, extraction time: 11:45 a.m. today" and "Unidentified male corpse, spleen hemorrhage sample, extraction time: 11:45 a.m. today". Then, she neatly placed the samples on the sample tray, together with the previously extracted samples.
"Teacher Zhang, the spleen-related samples have been extracted and labeled!"
“Okay,” Zhang Lin nodded, his gaze shifting to the deceased’s stomach. “Next, we will extract a sample of the stomach contents. Using a sterile scalpel, make a 3-centimeter incision in the middle of the stomach. Be gentle and avoid damaging the stomach wall. Then, using sterile forceps, carefully remove the stomach contents and place them in a sterile container. Label the contents with relevant information. The extraction amount will be approximately 50 grams. These will be sent to the laboratory for toxicology testing and digestibility analysis. The degree of digestion of the stomach contents will help determine the time of death. At the same time, we will investigate whether the deceased showed any signs of poisoning—although we haven’t found any signs of poisoning yet, for the sake of rigor, we must conduct toxicology testing to rule out all possibilities.”
"Understood, Teacher Zhang, I will cooperate with you to do a good job of sample extraction and labeling!" Xiao Lin quickly agreed, picked up the sterile scalpel and sterile container again, and handed them to Zhang Lin.
Zhang Lin took the instruments and carefully made a 3-centimeter incision in the middle of the deceased's stomach. The incision was clean and did not damage the stomach wall tissue. Then, he used sterile forceps to gently insert into the stomach cavity and carefully remove the stomach contents—mainly undigested rice and vegetable scraps, pale yellow in color, odorless, and without any abnormal color. It looked no different from the stomach contents of a normal person.
He carefully placed the stomach contents into a sterile container, extracting approximately 50 grams, and then handed it to Xiaolin. Xiaolin took the container and quickly labeled it: "Unidentified male corpse, stomach contents sample, extraction time: 11:50 AM today, extraction amount approximately 50 grams, main components are undigested rice and vegetable scraps, no odor, no abnormal color," and then placed the container on the sample tray.
"Teacher Zhang, the stomach contents sample has been extracted and labeled!"
Zhang Lin nodded, his gaze sweeping over the internal organs in the abdominal cavity once more. After carefully checking and confirming that no details had been missed and no other abnormalities were found, he said, "Alright, the abdominal dissection is complete. Xiao Lin, carefully cover the internal organs in the abdominal cavity with sterile gauze to prevent contamination. Then, record the time when the abdominal dissection ended."
"Understood, Teacher Zhang!" Xiao Lin quickly replied, picked up sterile gauze, and carefully covered the internal organs in the deceased's abdominal cavity. His movements were gentle, as if he was afraid of accidentally injuring the internal organs. Then, he glanced at the clock on the wall and quickly recorded: "Record: Abdominal dissection completed, time: 11:55 a.m.; Key findings of the abdominal dissection: The abdominal wound penetrated the abdominal wall, punctured the spleen, and caused massive bleeding from the ruptured spleen. Approximately 200 ml of blood was accumulated in the abdominal cavity. Cause of death confirmed: Acute hemorrhagic shock (caused by spleen rupture), other causes of death ruled out; Six relevant samples were collected from the abdominal cavity, namely: skin tissue sample around the abdominal wound, blood clot sample inside the abdominal wound, sludge residue sample inside the abdominal wound, blood sample inside the abdominal cavity, turbid fluid sample inside the abdominal cavity, tissue sample from the spleen injury area, spleen bleeding sample, and gastric contents sample (corrected here, actually 8 samples, Xiao Lin corrected in time). They have been marked and stored, with no omissions or errors."
Zhang Lin watched Xiao Lin diligently taking notes, nodded slightly, and a hint of approval flashed across his face. Then, he adjusted the angle of the operating light, shifting the light to the deceased's chest area, and said solemnly, "The abdominal autopsy is complete. Next, we will proceed with the thoracic autopsy. The focus of the thoracic autopsy is to examine the morphology and structure of the internal organs, ruling out any possible damage to them. Simultaneously, we will extract relevant samples from the thoracic cavity to help confirm the time and cause of death, further rule out other possible causes of death, and ensure the accuracy of the autopsy results."
"Understood, Teacher Zhang. I will cooperate with you throughout the process and do a good job of recording and sample collection!" Xiao Lin quickly agreed, and his pen was ready to be used for recording again. "Record: Abdominal dissection completed, time: 11:55 a.m. today; Next, we will conduct a thoracic dissection, focusing on examining the morphology and structure of the thoracic organs, ruling out damage to the thoracic organs, and collecting relevant samples to help confirm the time and cause of death."
Zhang Lin took a deep breath, picked up the sterile scalpel again, and said to Xiao Lin: "Chest dissection, incision direction: from the suprasternal notch of the deceased, along the midline of the sternum, down to below the xiphoid process, connecting with the abdominal dissection incision to form a complete longitudinal incision; incision angle: 25° to the skin, with the blade facing the inner side of the chest; incision force: even and moderate, avoiding excessive force that could damage the tissues, organs, and ribs in the chest cavity, and also avoiding too little force that would prevent the tissues from being cut open smoothly."
"Understood, Teacher Zhang. Recorded: Thoracic anatomy, defensive incision: along the midline of the sternum to below the xiphoid process, connecting with the abdominal anatomical incision; incision angle: 25°, blade facing the inner side of the chest; incision force: even and moderate." Xiao Lin quickly took notes, his eyes fixed on the scalpel in Zhang Lin's hand, ready to observe and cooperate.
Zhang Lin's scalpel fell again, landing steadily on the skin above the sternum of the deceased. Following the predetermined direction and angle, he slowly made his incision. As the scalpel moved, the skin, subcutaneous fat, pectoralis major, pectoralis minor, intercostal muscles, pleura, and other tissues of the deceased's chest were dissected one by one, each layer distinct and without any disorder.
The subcutaneous fat was about 1.5 cm thick, pale yellow in color, and evenly distributed, which was basically the same as the thickness of the subcutaneous fat in the abdomen, further confirming that the deceased's nutritional status before death was at a moderate level.
