1. Infection: Postoperative infections, such as surgical site infections (SSIs), can occur due to bacteria entering the wound. 2. Hemorrhage: Excessive bleeding during or after surgery can lead to hypovolemic shock. 3. Deep Vein Thrombosis (DVT): Blood clots forming in the deep veins, often in the legs, can lead to pulmonary embolism if dislodged. 4. Anesthesia Complications: Reactions to anesthesia, including respiratory depression and allergic reactions. 5. Respiratory Complications: Conditions like pneumonia or atelectasis can develop postoperatively. 6. Cardiovascular Complications: Events such as myocardial infarction or arrhythmias can occur after surgery. 7. Wound Dehiscence: The surgical incision may partially or completely open after surgery.
