Severe pancreatitis symptoms
Severe pancreatitis, due to different stages of pathological changes, presents diverse systemic responses. Generally, mild symptoms of pancreatitis include abdominal pain, nausea, vomiting, and fever. In severe pancreatitis, apart from these symptoms, due to bleeding, necrosis, and autolysis of the pancreas, additional symptoms such as shock, high fever, jaundice, abdominal distension, and paralytic ileus, peritoneal irritation signs, and subcutaneous ecchymosis may also occur. Abdominal pain is the earliest symptom, while nausea and vomiting are manifestations due to inflammatory factors stimulating the vagus nerve. The likelihood of jaundice is relatively low in acute edematous pancreatitis but is more common in severe pancreatitis. Extensive inflammatory exudation in the pancreas can lead to pancreatic necrosis and localized abscesses, which may cause varying degrees of fever increase.
Severe Pancreatitis Criteria
Acute pancreatitis with persistent organ failure lasting more than 48 hours is considered severe pancreatitis. In the early stages of the disease, organ failure starts with a systemic inflammatory response produced by the activation of a cytokine cascade, involving the continuous failure of single or multiple organs. Such patients often have one or more local complications, with organ failure that can persist for several days after onset. The mortality rate can reach 36% to 50% once organ failure occurs. Infections in such patients can dramatically increase the mortality rate. CT imaging may show gas bubbles in peripancreatic necrotic tissue and fluid collections. Diagnosis is confirmed by positive results from either a smear of aspirate obtained via image-guided fine-needle aspiration or from bacterial cultures.
What can be eaten with severe pancreatitis?
Patients with severe pancreatitis should not eat orally. Historically, suppressing pancreatic enzyme secretion by resting the intestines has been considered an important means of controlling the progression of acute pancreatitis. Currently, the implementation of early enteral nutrition is proposed. Early enteral nutrition should be administered via a jejunal tube, which is safer. The nutritional formulation should be chosen based on the patient's condition and intestinal tolerance. Initially, only glucose water may be used to allow the intestines to adapt to the nutrition. Early nutrition should use low-fat preparations containing amino acids or short peptides, because whole proteins entering the intestine directly without being digested by stomach acid can cause indigestion. As the condition enters the recovery phase, the feeding amount and rate can be gradually increased, and preparations containing whole proteins may be given.
How to take care of acute pancreatitis
Patients with pancreatitis should pay attention to their diet during the recovery period. The basic dietary principle for pancreatitis patients is to consume small amounts of easily digestible foods, with low protein and fat content, primarily carbohydrates. During acute episodes, it's crucial to strictly control the intake of fatty foods. Once the condition has improved, patients may gradually consume protein-rich, high-vitamin, high-carbohydrate foods, along with non-irritating, easily digestible foods. Patients should avoid consuming large amounts of meat and alcohol, and can eat rice soup, lotus root starch, noodles, etc.
Severe pancreatitis intestinal nutrition
In different stages of severe pancreatitis, the energy requirements vary. At the early onset of the disease, the principle of nutritional support is to provide the minimum metabolic substrates needed to maintain basic metabolic demands, correct metabolic disorders, and minimize protein loss to a reasonable level. Caloric provision should be between 20 to 25 kcal per kilogram per day. As the condition progresses, the focus of nutritional support gradually shifts towards increasing or balancing nutrient intake. Early intervention using jejunal tube feeding is considered safer. Formulas used should be tolerable by the intestines; initially, glucose water is used to help the intestines adapt to nutrition. Early use of low-fat formulas containing amino acids or short peptides is advisable. Additionally, whole proteins, after being digested by stomach acid and entering the intestines directly, may lead to poor absorption.
What medicine is used for pancreatitis?
In clinical practice, it is advised that patients with pancreatitis be hospitalized for treatment. The primary medications used during hospitalization mainly involve nutritional support, as patients with pancreatitis cannot eat and must refrain from ingesting food and water, necessitating the supplementation of water and electrolyte balance. Treatment primarily consists of using medications that reduce pancreatic secretion, such as choosing octreotide or similar drugs. Other drugs can be combined to inhibit pancreatic enzyme activity. However, while using these medications, it is important to consider using antibiotics to prevent infections in cases of pancreatitis. Overall, it is crucial to receive standardized treatment in a hospital for pancreatitis, as the condition can change rapidly and is relatively dangerous. (The use of medications should be under the guidance of a doctor.)
