What anesthetics are used for surgery?

There are various types of anesthetics used in surgery. Common ones include propofol emulsion injection, lidocaine hydrochloride injection, ropivacaine hydrochloride injection, fentanyl citrate injection, and vecuronium bromide for injection. These medications must be administered by trained medical professionals. If you have a history of allergy to anesthetics or experience any discomfort before surgery, it is recommended to inform your doctor in advance.

1. Propofol Emulsion Injection: This is a intravenous general anesthetic commonly used for induction and maintenance of general anesthesia. It rapidly induces unconsciousness and allows quick recovery after surgery. It is suitable for minor to moderate surgeries and endoscopic procedures.

2. Lidocaine Hydrochloride Injection: A local anesthetic that works by blocking pain signals in specific nerves when injected locally. It is commonly used for local infiltration anesthesia and nerve block anesthesia, such as in dental procedures or minor skin surgeries.

3. Ropivacaine Hydrochloride Injection: Another local anesthetic with a longer duration of action and relatively less impact on motor nerves. It is frequently used in epidural anesthesia, such as during cesarean sections or lower limb surgeries, helping to minimize delays in postoperative motor function recovery.

4. Fentanyl Citrate Injection: An opioid analgesic often used as an adjunct in general anesthesia to enhance anesthetic effects and reduce surgical pain. It can also be used for postoperative pain management. Caution is required due to potential side effects such as respiratory depression.

5. Vecuronium Bromide for Injection: A muscle relaxant used during general anesthesia to facilitate muscle relaxation, making surgical procedures easier—especially in major operations requiring abdominal or thoracic incisions. Mechanical ventilation is required when this drug is used, as it affects respiratory muscles.

Prior to surgery, follow your doctor’s instructions regarding fasting and avoiding fluids. Avoid staying up late and maintain good physical condition. After surgery, gradually resume eating as directed by your physician, get adequate rest, and avoid strenuous activities to support recovery from both anesthesia and the surgical procedure.
