Effect of different routes of administration on early cognitive function following inguinal hernia repair.
2021
PURPOSE To analyze the effects of different routes of dexmedetomidine administration on early cognitive function following inguinal hernia repair. METHODS A total of 83 patients with pediatric inguinal hernias admitted to our hospital from January 2018 to October 2020 were divided into control group (CNG, n = 41) and observation group (OG, n = 42) by random number table. The OG was given 2 μg/kg of dexmedetomidine hydrochloride by intranasal administration, and the CNG was treated with 0.5 μg/kg of dexmedetomidine hydrochloride via intravenous (IV) infusion pump. The hemodynamics, condition of anesthesia, awakening, and safety were compared between the two groups. RESULTS Systolic blood pressure and oxygen saturation levels at T1 and T2 in the OG were not different from those in the CNG (P > 0.05), and heart rates in the OG were all higher than those in the CNG (P < 0.05). The incidence of emergence agitation during awakening was 4.76% in the OG, which was lower than 21.95% compared with the CNG (P < 0.05). Ramsay sedation scores at 15 and 30 min after awakening in the OG were higher than those in the CNG, and PAED scores in the OG were lower than those in the CNG (P < 0.05). Cognitive, language, and motor scores in the OG were higher than those in the CNG at 3 days after surgery (P < 0.05), and the incidence of cognitive dysfunction was 4.76% in the OG at 3 days after surgery, which was lower compared with 21.95% in the CNG (P < 0.05). CONCLUSION Application of dexmedetomidine hydrochloride by intranasal administration or intravenous infusion before induction can ensure rapid postoperative awakening of the children without causing significant fluctuations in blood pressure and oxygen saturation, and both methods have a high safety profile. However, intranasal administration results in more satisfactory sedation, less postoperative agitation upon awakening, and reduces postoperative cognitive dysfunction.
