| Abstract | ||
| Background Functional endoscopic sinus surgery (FESS) is considered one of the most common ENT procedures. The main obstacle is impaired vision owing to excessive bleeding. Many drugs have been used to control such issues. Dexmedetomidine has a great affinity to α-adrenergic receptors. This research evaluated the hypotensive effect of intravenous against the intranasal dexmedetomidine in FESS. Materials and methods Patients randomized into 2 equal groups:Dexmedetomidine intravenous group (IV group) ( = 35): IV dexmedetomidine 1 μg/kg in 100 ml of normal saline (0.9%) was infused 15 min before starting anesthesia, followed by 0.5 μg/kg/h. At the same time, intranasal saline was given as a placebo.Dexmedetomidine intranasal group (IN group) ( = 35):IN dexmedetomidine (2 μg/kg) was given 15 min before induction, 1 ml in each nostril. At the same time, the patient received 100 ml of saline (0.9%)15 min before anesthesia, followed by IV saline as a placebo. The primary outcome was Boezaart’s grading scale. Other outcomes were the recorded hemodynamics, surgical satisfaction, sedation score, and adverse events. Results The calculated blood loss and Boezaart’s scale were lower in the IV group (p value < 0.001). Also, the IV group’s mean arterial blood pressure (MAP) and heart rate were significantly lower. The total intraoperative fentanyl dose was lower in the IV group. Surgeon satisfaction and sedation scores were significantly higher in the IV group. Conclusions Intravenous dexmedetomidine provides a better surgical field, more surgeon satisfaction, and lower blood loss for FESS. | ||
