ABSTRACT
Objective:To compare the accuracy of the needle tip reaching the target tissue between two subcutaneous injection techniques under ultrasound imaging in order to provide a basis for clinical injection to make a safe and reasonable decision.Methods:This was a parallel controlled non-inferiority comparative study. A total of 68 patients who received subcutaneous injections in the outpatient injection room of Nanjing Drum Tower Hospital Affiliated to Nanjing University from June 2021 to September 2022 were selected as the research subjects, and they were divided intothe A and B group according to the random number table method, there were 34 cases in each group. Group A received pinched skin injections, and group B received taut skin injections. Unify the injection site, injection needle length, and needle insertion angle. The accuracy rate of the needle tip reaching the target tissue, namely the subcutaneous fat layer, was compared between the two groups by ultrasound imaging, and the pain scores and the imaging performance during the injection process were observed.Results:The accuracy of the needle tip reaching the subcutaneous fat layer in the group A was 97.1%(33/34), which compared with the 100.0%(34/34) in the group B, there was no significant difference ( χ2 = 0.53, P>0.05). There was no significant difference about the distribution of pain scores between the two groups ( χ2 = 0.67, P>0.05). There were no significant differences about age, subcutaneous fat thickness and the distance from the needle tip to the myofascial in patients with different pain scores ( F = 1.20, 0.44, H = 0.64, all P>0.05). Conclusions:Under certain conditions, pinching the skin and tightening the skin have the same accuracy and safety when the needle tip reaches the subcutaneous fat layer of the target tissue, and the choice should be made according to the clinical situation. Imaging observations have enlightening significance for the practice of subcutaneous injection.
ABSTRACT
Objective To explore the personality characteristics of patients with chronic migraine complicating drugs overuse.Methods A total of 67 cases of migraine (control group) and 175 cases of medication overused migraine (MOH) were treated in the neurology department of this hospital from March to December 2016.The patients conformed to the migraine diagnostic criteria of the International Classification of Headache Disorders Third Edition (ICHD-3) formulated by the International Headache Society.The personality assessment adopted an internationally used Minnesota Personality Questionnaire.Results The scores of suspected disease,depression,rickets and social introgression in the observation group were higher than those in the control group,the difference was statistically significant (P＜0.05).In the observation group,there was a negative correlation between personality suspicion,rickets,neurasthenia,social introversion and education (P＜ 0.05).In the personality traits aspect of the observation group,hypochondriasis,hysteria,neuradynamia and social introversion were negatively correlated with the cultural degree (P＜0.05).Conclusion The personality changes in the four aspects of hypochondria,depression,hysteria and social introversion in the patients with MOH are more obvious than those in the patients with simple chronic migraine.
ABSTRACT
Through the analysis of Shenyang Medical College student's scientific research from 2007 to 2016, college student's scientific research has played an important role in promoting the cultivation of innovative talents, it has been an effective way that students understand the process of scientific research, cultivate scientific research ability, and that scientific research promotes teaching in university. College student's research should enhance the scientific and feasibility of the project selection, cultivate students the spirit of independent scientific research.
ABSTRACT
Objective To work out a flowchart for putting normal saline column by gravity drip via Groshong PICCs to guide intracavitary ECG and investigate the effect. Methods We developed the flowchart and trained the nurses to use it. Then the flowchart was used in catheteration of Groshong PICC to guide intracavitary ECG for 30 patients. Results The normal target rate was 93.3%(28/30) and the optimal tip target rate was 90.0%(27/30). The score on the flowchart by the nurses was (4.8 ± 0.4), indicating they were satisfied with it. Conclusion The flowchart for pushing normal saline column with gravity drip method via Groshong PICCs to guide intracavitary ECG provides an operational standard, enhancing the operational quality.
ABSTRACT
Aiming at the existing problems in the teaching hospital,teachers and practical students during clinical practice teaching,we explored actively in talent training and teaching base construction and promoted the improvement of clinical practice ability for medical students.
ABSTRACT
Objective To explore the diagnosis and treatment of abdominal cocoon. Methods The clinical data of 16 patients with abdominal cocoon were analyzed retrospectively . Result All the 16 patients with abdominal cocoon were treated and confirmed by operation. Before operation, 11 patients were misdiagnosed as mechanical intestinal obstruction, 4 as chronic appendicitis, and 1 as abdominal tumor.All patients were operated on and postoperative complications were found in 2 patients. All patients were curred clinically and followed up for 1-10years. 2 patients were died of relapsing intestinal obstruction 1,5 years after operation. 2 occurred relapsing incomplete intestinal obstruction accompaning with malnutrition, 12 patients were good during the follow up period. Conclusions Preoperative diagnosis of abdominal cocoon is difficult. The diagnosis mainly depends on the upper gastrointestinal radiography, B-ultrasonography and CT. Removal of the membrane and releasing the intestine adhesions is an effective method in treating this disease.
