Abstract:
Objective:To explore the effect of dexmedetomidine on cough reactions and related indexes during recovery from general anesthesia in thyroid tumor surgery.Methods:A total of 90 patients with thyroid tumor who underwent general anesthesia for thyroid tumor surgery from July 2019 to July 2021 in the First People's Hospital of Shangqiu City, Henan Province were selected and divided into the observation group (45 cases) and the control group (45 cases) according to the random number table method. The observation group was given dexmedetomidine 0.5 μg/kg intravenously at the beginning of the surgery, and the intravenous drip time should not be less than 10 min; the control group was given the same dose of normal saline intravenously. The recovery time and extubation time of the two groups were compared, and the incidence of cough reactions during the recovery from general anesthesia was compared. Changes of visual analogue scale (VAS) of pain at 6 h, 24 h and 48 h after surgery, and the changes of stress response indexes [cortisol (Cor), epinephrine (E) and norepinephrine (NE)] and pain factors [prostaglandin E2 (PGE2), neuropeptide Y (NPY) and β-endorphin (β-EP)] before and 48 h after surgery were compared.Results:The recovery time and extubation time in the observation group [(15.62 ± 3.64), (18.27 ± 4.25) min] were faster than those in the control group [(23.12 ± 4.53), (25.65 ± 3.89) min, P < 0.001]. The incidence of cough reactions during recovery from general anesthesia in the observation group [8.89% (4/45)] was lower than that in the control group [28.89% (13/45), P = 0.015]. The VAS score in the observation group was lower than that in the control group at 6 h, 24 h and 48 h after surgery ( P < 0.001). The levels of serum Cor, E and NE at 48 h after surgery in both groups were higher than those before surgery ( P < 0.001); and the serum Cor, E, and NE levels in the observation group were lower than those in the control group at 48 h after surgery ( P < 0.001). The serum PGE2 and NPY levels of the two groups at 48 h after surgery were higher than those before surgery, while β-EP level was lower than that before surgery ( P < 0.001); the serum PGE2 and NPY levels in the observation group were lower than those in the control group at 48 h after surgery, while β-EP level was higher than that in the control group ( P < 0.001). Conclusion:Dexmedetomidine can reduce the cough reactions during recovery from general anesthesia in thyroid tumor surgery, significantly reduce pain, and has little effect on stress response and pain factors.
