Construction of nomogram prediction model using heart rate and pulse perfusion variability index as predictors for hypotension in cervical cancer patients with spinal epidural anesthesia.

The prevention and treatment strategies for cervical cancer patients undergoing spinal epidural anesthesia have increasingly focused on early screening for high-risk factors associated with potential hypotension. We analyze the general conditions and preoperative examination results of 312 cervical cancer patients who received spinal epidural anesthesia, in order to identify independent risk factors for hypotension, assess their predictive efficacy, and construct a nomogram. 312 patients with cervical cancer received spinal epidural anesthesia were included in this study.

Analysis of the Relationship Between Periampullary Diverticulum and Recurrent Bile Duct Stones After Endoscopy on Magnetic Resonance Imaging of Magnetic Nanoparticles.

The objective of this work was to investigate the effect of magnetic resonance cholangiopancreatography (MRCP) based on super-paramagnetic iron oxide nanoparticles (SPIONs) on the recurrence diagnosis of periampullary diverticulum (PAD) and bile duct stone (BDS), so as to provide a scientific research basis for the recidivation factors of bile duct stones in clinic. Patients with PAD diagnosed in hospital from July 2019 to March 2021 (who had undergone endoscopic gallstone surgery) were selected for study in this work. They were rolled into two groups, the parapapillary group (123 cases) and the cholangiopancreatic duct directly opening in the diverticulum group (97 cases), according to the clinical classification.
