Abstract
BackgroundTo investigate the effect of intravenous injection of dexmedetomidine combined with parecoxib sodium on sedation and anxiety and stress response of tracheal intubation in patients undergoing functional endoscopic sinus surgery.MethodsOne hundred twenty patients undergoing endoscopic sinus surgery were randomly divided into four groups: group DP, group D, group P and group N. The blood pressure (BP), heart rate (HR), blood oxygen saturation (SPO2), EEG, bispectral index (BIS), Ramsay sedation score and state anxiety questionnaire (SAI) were recorded before administration (T0), 10 min (T1), 20 min (T2) and 30 min (T3) after administration. After 30 min, endotracheal intubation was performed after anesthesia induction. The BP, HR, SPO2 were recorded 1 min before intubation (T4), intubation (T5), 3 min (T6) after intubation, 5 min (T7) after intubation, and blood samples were collected from patients before administration and after intubation 2 min to detect serum cortisol (Cor), adrenalin (E) norepinephrine (NE) and blood glucose (BS).ResultsThere was no significant difference in Ramsay sedation score before anesthesia, but the Ramsay sedation score in group D、DP was significantly higher than that in group P and group N, the BIS, BP, HR and anxiety scores were significantly lower than those in the group P and group N (p < 0.05). There was no significant difference in Ramsay sedation score, BIS value, anxiety score and BP, HR between group D and group DP (p > 0.05). Compared with T4, there was no significant difference in BIS and BP, HR in group D, group DP and group P (p > 0.05), but the BIS, BP and HR in group N were significantly higher than T4, (p < 0.05). Three minutes after intubation there was no statistical difference in the changes of Cor, E, NE and BS values compared with before intubation in group P and group DP (p > 0.05), but the changes of Cor, E, NE and BS values were significantly lower than that in group N (p < 0.05). Compared with T0, the values of NE, E, Cor, BS decreased in group D, DP and P at T4, group DP decreased more significantly than group D (p < 0.05). while the NE, E, Cor, BS of T6 are at the same level as the base value. In group N, the NE, E, Cor, BS of T4 were at the same level of T0, but significantly higher at T6.And at T6, NE and E in group D, P and N were significantly different from those in group DP (p < 0.05).ConclusionPreoperative intravenous infusion of dexmedetomidine combined with parecoxib sodium by functional nasal endoscopy can not only calm and resist anxiety, but also better prevent stress response of endotracheal intubation, which is a safe and effective way of preoperative medication.Trial registrationChiCTR-OPN-17010444.

Summary
To investigate the effect of intravenous injection of dexmedetomidine combined with parecoxib sodium on sedation and anxiety and stress response of tracheal intubation in patients undergoing functional endoscopic sinus surgery. We used dexmedetomidine combined with parecoxib sodium in patients undergoing FESS surgery. From the aspects of preoperative sedation, antianxiety and intubation stress, we evaluated the clinical effect of dexmedetomidine combined with parecoxib sodium in FESS surgery, in order to find a suitable preoperative anesthesia medication for FESS. It could provides a direct clinical basis and reference for anesthesiologists to implement comfortable and safe anesthesia
