How to protect T-tube and ensure smooth drainage? As a guest, we should cooperate with medical staff to observe whether there are inflammatory and corrosive blood clots, necrotic and exfoliated tissues, purulent secretions, sediment-like stones, ascaris, etc. Block the lumen. If yes, immediately tell the personnel on duty to deal with it, and adopt methods such as washing, squeezing and guide wire dredging. Always pay attention to the distortion and oppression of rubber pipes and correct them in time.

Only by ensuring the smooth drainage of T-tube can the bile containing toxic pus in biliary tract be quickly excreted and the condition will be quickly improved. When the patient turns over, be careful that the "T" tube is pulled excessively and slipped, especially within one week after operation. Once the T-tube slips carelessly, it will increase the pain and economic burden, and in severe cases, it will cause biliary peritonitis and septicemia. Patients will have symptoms of peritoneal irritation (they will jump up when pressing their abdomen with their hands), abdominal distension and shock, accompanied by obvious high fever, chills, rapid pulse, jaundice and vomiting, which will eventually lead to the danger and pain of reoperation.
