Postoperative care after laparoscopic splenectomy mainly includes observation of wound condition, changes in drainage fluid and platelet changes. 1. Observation of wound condition: Observe the surgical wound, whether there is any blood seepage, some patients’ wounds are infected, there will be redness, swelling, hardness and abscess formation, pay attention to keep the wound clean, avoid infection, and promote the recovery of the wound. 2. Changes in drainage fluid: observe whether the drainage fluid is smooth, and record the changes in the color of the drainage fluid and the amount of fluid, so as to clarify the infection situation and avoid the accumulation of fluid in the abdominal cavity. 3. Platelet changes: after surgical resection, patients are prone to platelet rise, if the platelet rise is obvious, it is necessary to inform the doctor in time to avoid the formation of venous thrombus by platelet rise, which will lead to tissue and organ embolism. After laparoscopic splenectomy, patients should pay attention to supplemental nutrition, eat more fresh fruits and vegetables, avoid spicy and stimulating food, drink appropriate amount of water, ensure wound hygiene, proper exercise, avoid strenuous activities.
