ObjectiveTo explore the infection condition of Acinetobacter baumannii at the Neurosurgery Intensive Care Unit (NICU), and analyze the possible risk factors. MethodsWe retrospectively analyzed the clinical data of Acinetobacter baumannii infection patients with craniocerebral injury treated at the NICU between January 2011 and June 2013. We collected such information as infection patients' population distribution, infection site, invasive operations and patients' nurse-in-charge level and so on, and analyzed the possible risk factors for the infection. ResultsThirty-one patients were infected with Acinetobacter baumannii, and they were mainly distributed between 60 and 80 years old. The main infection site was lower respiratory tract, followed in order by urinary tract, gastrointestinal tract, skin and soft tissue. The risk factors might be related to age, invasive operation, nurse working ability, etc. ConclusionThe patients at the NICU are vulnerable to infection of Acinetobacter baumannii. Reducing invasive diagnosis and nursing procedures, providing optimal care, and carrying out specialized nurse standardization training may be the important means to effectively reduce the infection.
ObjectiveTo explore the value and role of post-processing techniques such as 3D reconstruction in the online education mode in neurosurgery undergraduate clinical probation teaching.MethodsA retrospective analysis method was used to collect 120 clinical 5-year medical students who were trained in neurosurgery at West China Hospital of Sichuan University from January 2019 to May 2020, including 40 students receiving traditional imaging materials offline (control group 1), 40 students being taught on image post-processing technology offline (control group 2), and 40 students being taught on-line image post-processing technology during the novel coronavirus epidemic (observational group). The students’ scores of departmental rotation examination and feedback survey results on teaching satisfaction were collected, and multiple comparison was conducted between the observational group and the two control groups respectively.ResultIn the control group 1, the control group 2, and the observational group, the theoretical test scores were 36.80±3.22, 38.17±2.61, and 38.97±2.79, respectively; the case analysis scores were 37.05±2.01, 38.40±2.62, and 39.25±2.88, respectively; the total scores were 73.85±5.06, 76.57±4.29, and 78.10±4.53, respectively; the scores of interest in teaching were 84.47±3.71, 86.05±2.87, and 86.82±2.60, respectively; the scores of mastery of knowledge were 82.85±4.39, 84.90±2.72, and 85.78±2.36, respectively; and the scores of overall satisfaction with teaching were 84.17±3.45, 85.97±2.64, and 86.37±2.59, respectively. The differences among the three groups were all statistically significant (P<0.05). The observational group differed significantly from the control group 1 in all the above scores (P<0.05), while did not differed from the control group 2 in any of the above scores (P>0.05).ConclusionsIn neurosurgery internship activities, the online application of image post-processing techniques such as 3D reconstruction will help students establish 3D spatial concepts, better understand the brain anatomy, and improve students’ academic performance and acceptance.
To investigate the microsurgical management of cranionasal tumors and the method of the reconstruction of the skull base. Methods From June 2005 to October 2007, 20 patients with cranionasal tumor were treated. There were 10 males and 10 females, aged between 13 and 77 years (median 49 years). The disease course was 2 months to 13 years.The cranionasal tumors, proved by MRI and CT scans, located in the anterior skull base, paranasal sinus, nasal and/or orbit cavity. And their cl inical presentations were l isted as follows: dysosphresia in 14 patients, headache in 11 patients, nasal obstruction in 9 patients, epistaxis in 8 patients, visual disorder in 4 patients, exophthalmos in 4 patients and conscious disturbance in 2 patients. All 20 patients underwent transbasal surgery combined with transnasal surgery, and tumors were resected by one-stage operation. The skull base was reconstructed by surgical technique “Pull Down Sandwich” with pedicle periosteum flap. Results Tumors were resected by one-stage operation, and the anterior skull bases were reconstructed. Pathological examination showed 8 cases of mal ignant tumors and 12 cases of benign tumors. The total surgical excision was complete in 16 patients, and 4 patients with subtotal excision. There was no operative death. Eighteen patients were followed up 3 months to 2 years and 6 months. Transient cerebrospinal fluid rhinorrhea was found in 2 cases which were cured by lumbar drainage. And recurrence of tumor was observed in 5 patients 3 months to 2 years after operation. Conclusion Microsurgical operation via subfrontal approach assisted bytransnasal endoscopy is an effective method in management of cranionasal tumors, with the advantages of econstruction of the skull base with pedicle periosteum flap or “Pull Down Sandwich” and low compl ication rate.
ObjectiveTo explore the effect of the cluster intervention in new nurses in the Department of Neurosurgery in occupation training, so as to provide reference for the clinical training of new nurses. MethodsEight nurses who entered the Department of Neurosurgery in January 2013 were set as control group and the 8 new nurses entering in January 2014 as the observation group. The control group was adopted the traditional training methods, while the observation group underwent used extra cluster intervention. The differences in the results of theory, technology, operation and the 360-degree evaluation between the two groups were analyzed at the end of year. ResultsIn the observation group, the median theory examination score was 91.50, median operation assessment grades was 95.00, which were higher than those in the control group (82.00 and 83.00). The average scores of 360-degree evaluation in the observation group were higher than those in the control group with a significant difference (P < 0.01). ConclusionsIntensive intervention should be used for new nurses' training. It helps to improve the training effect and new nurses' ability.
Objective To understand the current status of the preferences and opinions on the investigator-initiated trails (IIT) of the neurosurgeons participating in INTERACT3 in China, as well as the design preference for IIT projects, and to provide a basis for the design and organization of multi-center clinical studies in the future. Methods Neurosurgeons with different seniority and professional titles from 89 domestic research institutions participating in the INTERACT3 project were collected from September to October 2023. The questionnaires were collected by questionnaire star. Results A total of 56 valid questionnaires were collected from 29 units. Among the 56 respondents, 52 neurosurgeons (92.86%) were from teaching hospitals and 45 (80.36%) were from grade A tertiary hospitals. 30 neurosurgeons (53.57%) had experience in conducting various clinical studies, and 55 neurosurgeons (98.21%) had experience in participating in various clinical studies. The main purposes of presiding over or participating in clinical research focused on “accumulating relevant experience and preparing for future projects” and “standardizing clinical diagnosis and treatment”, which were 89.29% and 83.93%. Respectively, regarding the way the case report form completing, respondents preferred to use electronic data collection systems (83.93%). Conclusions The purpose of the neurosurgeons interviewed to host or participate in clinical research is mainly to assist clinical and scientific research. Economic reasons have little impact on whether to participate in clinical research. The rationality and ease of operation of the trail design are the keys to attracting respondents to participate in clinical researches, and the level of remuneration has little impact on the decision-making of the respondents. The safety of clinical studies and the difficulty of enrolling subjects are the key factors that hinder respondents’ participation in clinical studies.
Objective To systematically review the clinical effectiveness and safety of sufentanil-propofol versus remifentanil-propofol during total intravenous anesthesia for neurosurgery. Methods Databases including The Cochrane Library (Issue 3, 2013), the database of the Cochrane Anesthesia Group, MEDLINE, EMbase, PubMed, Ovid, Springer, CNKI, VIP and WanFang Data were electronically searched from inception to May 2013 for the randomized controlled trials (RCTs) of sufentanil-propofol versus remifentanil-propofol during total intravenous anesthesia for neurosurgery. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the quality of included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results Thirteen trials involving 647 patients were finally included. The results of meta-analysis showed that: a) for hemodynamic changes, MAP decreased in the remifentanil-propofol group after induction and decreased 5 minutes after intubation, but no significant difference was found between the two groups; the two groups were alike in MAP changes during craniotomy and extubation, and in HR changes after induction, 5 minutes after intubation, during craniotomy and extubation, with no significant difference. b) The result of intra-operative wake-up test showed that, there was no significant difference in the sedative effect and the time of awaking between the two groups. c) For emergence time and extubation time, compared with the sufentanil-propofol group, emergence time and extubation time were significantly shorter than those in the remifentanil-propofol group. d) For side effects, there was no significant difference in side effects (such as post-operative nausea, vomiting, respiratory depression, restlessness, chills and hypotension) between the two groups. And e) for post-operative pain, compared with the remifentanil-propofol group, post-operative 1-h and 2-h VAS were lower and the number of who need additional analgesic drugs within 24 h after operation was less in the sufentanil-propofol group, with significant differences. Both groups used the similar dosage of propofol with no significant difference. Conclusion Compared with the remifentanil-propofol group, hemodynamics changes in the sufentanil-propofol group is steadier after induction and during intubation. Patients in the sufentanil-propofol group are better in postoperative awakening quality. But they are alike in the incidence of side effects and propofol dosage.
