This retrospective study investigated the effects of three dexmedetomidine (Dex) injection approaches on analgesic and hemodynamics in elderly cholecystolithiasis patients undergoing laparoscopic cholecystectomy. The clinical data of 150 elderly patients with cholecystolithiasis were collected, and they were divided into the Dex A (n=50), Dex B (n=50), and Dex C (n=50) cohorts. Patient's heart rate (HR) and mean arterial pressure (MAP) were collected at T0, T1, and T2 for blood gas analysis. The difference in oxygen content between cerebral arterial and venous blood (Da-jvO2) was calculated. The duration of surgery, occurrence of cardiovascular and respiratory suppression, and the time of spontaneous respiratory recovery and extubation were recorded. At T2, T3, and T4, HR and MAP in the Dex C group were smaller than Dex A group and Dex B group (Dex C

Objective: Our study tried to evaluate and compare the therapeutic efficacy of intratympanic injection of dexamethasone (DEX) at different concentrations for the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL).
Methods: A prospective randomized controlled study was conducted on 203 patients with unilateral ISSNHL. Patients were divided into four groups: the control group (n = 47, systemic treatment only), the high-concentration group (n = 51, intratympanic injection of DEX 20 mg/ml), the medium-concentration group (n = 55, 10 mg/ml), and the low-concentration group (n = 50, 5 mg/ml).

Objective: The aim of this prospective randomized double-blind study is to evaluate whether oral dexmedetomidine (DEX) premedication could increase sedation in order to reduce preoperative anxiety and inhibit stress response during general anesthesia tracheal intubation.
Materials: A total of 100 ASA I and II adult patients undergoing elective neurosurgery were randomly divided into the control group (C group, n = 50) and the oral DEX premedication (DEX group, n = 50). Patients were administrated 4 μg/kg dexmedetomidine orally pre-anesthesia 120 min.
