Comparison between Dexmedetomidine and Midazolam for Sedation in Patients with Intubation after Oral and Maxillofacial Surgery

Comparison between Dexmedetomidine and Midazolam for Sedation in Patients with Intubation after Oral and Maxillofacial Surgery:



The aim of the investigation is to clarify the beneficial sedative effects for patients with postoperative intubation in the intensive care unit (ICU) after oral and maxillofacial surgery. Forty patients with postoperative intubation were divided into two groups in method of random number table: midazolam group and dexmedetomidine group. The Ramsay score, the behavioral pain scale (BPS) score, SpO2, HR, MAP, and RR were recorded before sedation (T0), 30 minutes (T1), 1 hour (T2), 2 hours (T3), 6 hours (T4), and 12 hours (T5) after dexmedetomidine or midazolam initiation in intensive care unit, and 10 minutes after extubation (T6). The rate of incidences of side effects was calculated. Sedation with midazolam was as good as standard sedation with dexmedetomidine in maintaining target sedation level. The BPS score in the midazolam group was higher than that in the dexmedetomidine group. The time of tracheal catheter extraction in the dexmedetomidine group was shorter than that in the midazolam group (). The incidence of bradycardia in the dexmedetomidine group was higher than that in the midazolam group (). There was no statistically significant difference in the incidence of hypotension between the two groups (). The incidence of respiratory depression of group midazolam was higher than that of group dexmedetomidine (). The incidence of delirium in the dexmedetomidine group was significantly lower than that in the midazolam group, and the difference was statistically significant (). Dexmedetomidine and midazolam can meet the needs for sedation in ICU patients. And dexmedetomidine can improve patients’ ability to communicate pain compared with midazolam.
