Investigation of Factors Affecting Body Temperature Changes During Routine Clinical Head Magnetic Resonance Imaging

Objectives: The purpose of this study was to examine the diffusion patterns of new medical technologies in Korean hospitals. We also sought to identify critical factors leading to the decision to acquire capital-intensive medical technology. The rationale and timing of magnetic resonance imaging (MRI) acquisitions were retrospectively evaluated according to a “whether, when, and why” paradigm.Methods: We analyzed data pertaining to 232 hospitals with active medical residency programs. Of these, 185 hospitals owned or leased an MRI unit, and 47 had not acquired units as of June 2004. Data were collected from the Ministry of Health and Welfare, Korean National Statistical Office, and Korean Hospital Association databases, and variables were identified and classified as predisposing, enabling, or reinforcing factors.Results: The MRI diffusion rate curve was linear for two types of hospital but was S-shaped for tertiary hospitals, which were early adopters of MRI. Significant predictors for MRI adoption included the per capita number of regional physicians (+), total number of existing regional MRI units (−), percentage of the regional population over 65 years of age (+), private ownership of the hospital, presence of a radiology residency program, number of beds (+), and regional per capita taxable income (+).Conclusions: Diffusion of MRI technology is occurring rapidly across Korean hospitals. The factors affecting MRI adoption in Korea are similar to the factors documented in other countries, namely regional population over age 65, regional income per capita, large hospitals, and teaching hospitals. This study provides baseline information for predicting diffusion patterns of other new and/or expensive medical technologies.

Objective: In this paper, a lattice algorithm is used to explore the effect of MRI on anesthesia when used in neurosurgery. Methods: Sixty patients with glioma were randomly divided into two groups. Thirty patients underwent intracranial glioma resection (iMRI group) under the guidance of intraoperative magnetic resonance imaging (iMRI) and functional neuronavigational, and 30 patients underwent functional neuronavigational. Guide the traditional resection of traditional craniotomy gliomas (group N), and record the general situation, anesthesia time, operation preparation time, operation time, intraoperative blood loss, infusion volume, blood transfusion rate, preoperative and postoperative hemoglobin concentrations, Postoperative body temperature, dosage of muscle relaxant, perioperative accidents related to iMRI and anesthesia. Results: Compared with the N group, the general conditions, anesthesia time, intraoperative blood loss, infusion volume, blood transfusion rate, hemoglobin concentration, and postoperative body temperature of the patients in the iMRI group were not significantly different (P > 0.05), but the time for preparation and operation. It was significantly prolonged, and the amount of muscle relaxant was significantly increased (P < 0.05). There were no accidents related to iMRI and anesthesia in both groups. Conclusion: The use of iMRI in neurosurgical surgery improves the accuracy of surgery and makes tumor resection more complete, but the operation time is significantly longer, and other perioperative characteristics are not different from traditional neurosurgery. iMRI is used for anesthesia in neurosurgery. In addition to following the general principles of neurosurgery anesthesia, attention should also be paid to the regulation of anesthesia for long-term surgery.
