Anesthesia is a medical procedure that temporarily renders a patient unconscious or impaired by medication or other methods. Strict adherence to protocols is essential to ensure safety. Precautions include preoperative assessment, fasting requirements, intraoperative monitoring, postoperative care, and management of special populations to prevent complications.
Preoperative Preparation: Comprehensive Health Assessment: Inform the doctor of any past medical history (e.g., heart disease, hypertension, allergies), long-term medications (e.g., anticoagulants, hormones), and smoking/drinking habits to allow for adjustments to the anesthesia plan.
Strict Fasting and Abstention from Drinking: Adults must fast for 8 hours and abstain from drinking for 2-4 hours preoperatively. For children, the fasting period can be shortened (e.g., 4 hours for breastfeeding, 6 hours for formula) to prevent aspiration during surgery.
Psychological Preparation: Alleviate anxiety and fully understand the anesthesia method, risks, and alternative treatments before signing the informed consent form.
