The tubes on pancreatitis patients mainly include: gastric tube, nasal intestinal tube, abdominal double cannula, pig tail drainage tube, abdominal red catheter/white plastic tube drainage catheter, nasobiliary tube, etc. These tubes are vital to the treatment of pancreatitis, whether you are living in the hospital or have brought the tubes home to recuperate, please make sure to make efforts to keep each tube in place and unobstructed. If the tape or 3M tape used to fix the catheter is wet or the adhesiveness is reduced, please replace it in time; and pay attention to observe any changes in the line, volume and color of the drainage fluid, and calculate the amount of drainage in and out if necessary, and contact the original bedside doctor in time if abnormalities are found. (a) double casing of the abdominal cavity: 1, to ensure the effective operation of the negative pressure suction device, those who still need continuous suction after discharge need to purchase a vacuum negative pressure machine, adjust the appropriate negative pressure value (about 20mmHg), to ensure that the drainage bottle airtight, to prevent leakage caused by insufficient negative pressure; 2, identify clearly the inlet pipe and negative pressure suction tube, properly connect and fix the joints, intermittent activity of the negative pressure internal cannula, to ensure that the head end without necrotic tissue Blockage; 3, external flushing saline after the use of timely replacement of bags to prevent dry suction. (B) abdominal pigtail drainage catheter: The pigtail tube of Nanjing General Hospital of Nanjing Military Region Pancreatitis Treatment Center is divided into simple drainage tube and cooperative drainage tube, please learn to distinguish between the two types of drainage tubes under the guidance of doctors, and learn to perform abdominal flushing; 1. simple drainage tube means that the drainage tube only drains a regional pus cavity, and there is no other outlet for the pus cavity, which needs to be flushed and drained in the early stage, and can be passively drained after the reduction of necrotic tissue in the later stage. Passive drainage, the rubber tube should be squeezed intermittently to achieve the purpose of promoting drainage of pus cavity and keeping the pipeline unobstructed; 2.cooperative drainage tube means the same drainage area has more than or equal to two or more drainage devices, usually these drainage tubes are interoperable, and the flushing with external flushing water should be given intermittently in daily management to achieve the purpose of scrubbing, diluting pus, promoting thorough drainage of pus cavity and the growth of granulation of pus cavity wall. The flushing can be done with one inlet and other drains, with each drainage tube alternating. If the flow rate of the flushing drainage fluid is slow, the drainage tube can be moved appropriately and slightly (50px of activity). When flushing, we need to pay attention to the observation to ensure that the drainage is unobstructed, to achieve “in and out, in and out balance”. (C) abdominal red catheter / white plastic tube drainage catheter: 1, divided into simple drainage tube and synergistic drainage tube, specific management methods are the same as the abdominal pig tail drainage catheter; 2, the replacement of red catheter drainage tube is often late in the course of the disease, the sinus tract is basically mature, the drainage tube can be flushed with a greater degree of activity to achieve maximum drainage effect, but need to ensure that the position of the line before and after flushing unchanged; 3, when flushing need to pay attention to Observation, to ensure smooth drainage, to achieve “in and out, in and out balance”. (4) Nasal and intestinal tube 1. Keep the tube unobstructed: it is necessary to flush the tube carefully, find the tube unobstructed/blocked in time, and report to the nurse/doctor in time. Commonly used flushing solution: warm water, Coca-Cola, sodium bicarbonate solution, etc.; flushing frequency: 1 time/2 hours; diligently check the fixed tape, replace it when it is loose, pay attention to protect the nasal intestinal tube when moving, prevent environmental objects from pulling and dragging the nasal intestinal tube; 2, nasal feeding nutritional varieties: most patients need to add surimi under the guidance of doctors during the rehabilitation phase, please try to choose thin and less crumbly food, because the condition requires infusion If you need to infuse food containing more fiber and more viscous food, you need to increase the frequency of flushing; try to infuse at a constant speed, and if necessary, infuse with enteral nutrition infusion pump; try to avoid solid particle-like food infusion, filter before infusion, and flush the tube after infusion; pay attention to the temperature of infused food, the interaction of infused food, the height of suspension of nutrition solution during gravity infusion, and other factors.
