Analgesic Effects of Dexmedetomidine Combined with Spinal and Epidural Anesthesia Nursing on Prostate Hyperplasia Patients after Transurethral Resection of Prostate by Intelligent Algorithm-Based Magnetic Resonance Imaging.

To analyze the investigation of the application effects of different doses of dexmedetomidine (Dex) with combined spinal and epidural anesthesia nursing on analgesia after transurethral resection of prostate (TURP) by intelligent algorithm-based magnetic resonance imaging (MRI), MRI imaging segmentation model of mask regions with convolutional neural network (Mask R-CNN) features was proposed in the research. Besides, the segmentation effects of Mask R-CNN, U-net, and V-net algorithms were compared and analyzed. Meanwhile, a total of 184 patients receiving TURP were selected as the research objects, and they were divided into A, B, C, and D groups based on random number table method, each group including 46 cases.

Influence of Anesthetic Brochure on Patient's Information Gain, Preoperative Anxiety, Trust, and Satisfaction.

Objective To assess the impacts of anesthetic brochure on anesthetic information gain, preoperative anxiety, trust to anesthesiologists, and satisfaction to the preanesthesia visit for patients undergoing general anesthesia. Methods Totally 134 patients scheduled for elective thyroid surgery under general anesthesia in Peking Union Medical College Hospital were assigned to two groups using the random number table method, among whom 68 patients received brochure before preoperative visit (brochure group) and 66 patients did not (control group). Questionnaires with items for evaluating patient's information gain, preoperative anxiety and trust were completed after preanesthetic visit.
