A prospective, randomised double-blind study on the anaesthetic effect of dexmedetomidine hydrochloride in brainstem tumour surgery

“…Although brainstem tumour surgery is still very risky, the rate of intraoperative accidents can be reduced if surgical resection is only conducted for limited, nodular, or cystically degenerated and well-differentiated tumours [4]. For benign brainstem tumours, total resection is usually performed to achieve a radical resection effect, while malignant tumours are usually treated with a combination of chemotherapy and radiotherapy [6]. In traditional brainstem tumour surgery, anaesthetics usually include propofol, ropivacaine and midazolam.…”

“…Although they can help to reduce the pain of patients and maintain sedation during surgery, postoperative mental confusion and consciousness delay often occur [7]. In recent years, due to medical improvements and the continuous development of microsurgical techniques, the survival rate of patients undergoing brainstem tumour resections has been significantly improved through combining it with radiotherapy, and some patients can be completely cured [6].…”

“…Due to the small size of the brainstem and the large number of nerves, as well as their wide distribution, brainstem tumour surgery is one the most difficult and dangerous surgeries, with accidents easily occurring [4]. In recent years, treatment methods for brainstem tumours have been continually improving and the success rate of brainstem tumour surgery has significantly increased; nevertheless, efforts are still needed to reduce the injury rate in patients during brainstem tumour surgery [5, 6]. To allow patients to experience a safer, more comfortable and painless process during brainstem tumour surgeries, our hospital introduced dexmedetomidine hydrochloride to improve the quality of anaesthesia.…”
