Clinical Study of Dexmedetomidine Administered Intranasally to Relieve Perioperative Anxiety and Depression in Patients With Colorectal Tumors

About This Trial

Currently, domestic and international research on dexmedetomidine as well as anxiety and depression is more focused on basic research. In terms of clinical research, dexmedetomidine is more often used in pediatrics, short surgeries, intensive care units, etc., for sedation and analgesia; while less research has been done for the relief of anxiety and depression. At present, on the one hand, the number of oncology patients is on the rise both at home and abroad, and on the other hand, anxiety and depression account for an increasing proportion of healthcare in the world. Tumor patients, as a high prevalence group of anxiety and depression, their prognosis and regression are also more complicated. Therefore, exploring the role of intranasal administration of dexmedetomidine in relieving perioperative anxiety and depression in oncology patients has a very strong practical basis and clinical significance.

Treatments Being Tested

DRUG

Dexmedetomidine administered intranasally

Intranasal administration of dexmedetomidine (plain) was given at the bedside of the ward as per the pre-tested recommended dose. The patient's vital signs were maintained. On the day of surgery, 30 min before induction of anesthesia, intranasal dexmedetomidine (original solution) was administered in the operating room at the pre-tested recommended dose.
