Total intravenous anesthesia (TIVA) is maintained by intermittent or continuous combined intravenous injection of a variety of short-acting intravenous anesthetics, which can provide safe and rapid induction, maintenance and termination of general anesthesia. It has a slight effect on respiration and circulation, strong controllability, short anesthetic recovery time, reduced postoperative nausea and vomiting (PONV) and quick discharge time, so it has been widely used in clinic. Functional endoscopic sinus surgery is a common method for the treatment of sinusitis and other diseases. The trauma of this operation is less. The use of TIVA during the operation can reduce the bleeding in the surgical field and is beneficial to the recovery of patients.
The combination of propofol and remifentanil is the most common in TIVA because of its fast pharmacokinetics and short half-life. However, the disadvantage of remifentanil is the lack of residual analgesic effect after termination of continuous infusion. As postoperative nasal packing can still bring postoperative pain, patients with severe discomfort caused by pain will have unexpected conditions such as surgical incision cracking and bleeding, which will affect the effect of operation and rehabilitation. Afentanil is another opioid drug with short effect and strong analgesic effect. Previous studies have shown that remifentanil-based TIVA has slightly higher postoperative pain and early use of analgesics than TIVA in discectomy. Because the effect of TIVA using Afentanil or remifentanil on postoperative pain in functional nasal endoscopic surgery is not clear, this study intends to observe the effect of TIVA on postoperative pain in patients undergoing functional nasal endoscopic surgery under general anesthesia, so as to optimize the clinical anesthetic scheme of this kind of minimally invasive surgery and provide clinical reference.
This study intends to observe the effect of TIVA using afentanil or remifentanil on postoperative pain in patients undergoing functional nasal endoscopic surgery under general anesthesia.
Main indicators:
VAS score at 30 min after operation.
Secondary indicators:
VAS score of 60 min after operation. VAS score of 24h after operation. Number of cases of postoperative use of analgesics . Number of cases of postoperative adverse reactions.

| VAS score | the digital rating scale (VAS) uses a number between 0 and 10 to indicate that there is no pain; a score of 1-3 means that a slight pain can be tolerated; a score of 4-6 indicates that it is bearable if it does not affect sleep; a score of 7-10 indicates that it is becoming more and more painful and unbearable, affecting appetite and sleep | Postoperative 30minutes |
