ABSTRACT
Objective:To explore the early diagnosis and correct treatment of neurogenic pulmonary edema (NPE) and review the literature.Method:Retrospective analysis was performed in six patients diagnosed as NPE who were admitted to the emergency department of Tianjin Third Central Hospital from March 2017 to March 2021.Results:Six patients had acute onset, presenting severe dyspnea and hypoxemia, and obvious wet rales could be heard in both lungs. The white blood cell count (WBC) increased to varying degrees (11-22)×10 9/L, procalcitonin (PCT) was normal, or slightly increased, sputum bacteriological examination was negative, and oxygenation index was < 200 mmHg (1 mmHg≈0.133 kPa). Chest CT mainly showed patchy or patchy exudation. The lesions were of different sizes and were not distributed according to lobes. By reducing intracranial pressure, ventilator assisted breathing, liquid therapy, anti-infection therapy with antibiotics, nutritional support, all six patients were well and discharged, and no one died of NPE. Conclusions:NPE has complex condition, acute onset and rapid development. Early diagnosis and correct treatment can improve the success rate of treatment and prognosis of patients with NPE.
ABSTRACT
The quality of public cardiopulmonary resuscitation training plays an important role in improving the survival rate of patients with cardiac arrest. Various forms of training have been carried out all over China, which plays a great role in promoting the work of cardiopulmonary resuscitation. However, there is still a lot of room for improvement in the quality management and effect sustainability of training. This paper reviews the current situation and deficiencies of quality management of public cardiopulmonary resuscitation training, and the role of training quality in enhancing people's self-confidence in learning and rescue, training contents, training methods, quality evaluation indicators, evaluation methods, and quality influencing factors and retraining time requirements, and so on. And it puts forward some practical suggestions on the quality management of public cardiopulmonary resuscitation training in China. Such as it will more emphasize standardized training, deliberate practice, proficient training, National Training, long-term maintenance of knowledge and skills, and using useful tools to improve the quality of cardiopulmonary resuscitation training, etc. In order to improve the training quality management level of the public, so that the trainees can really master cardiopulmonary resuscitation skills, so as to improve the rescue rate and survival rate of patients with cardiac arrest. To promote the sustainable development of people's health.
ABSTRACT
Objective@#To explore the effect of distance education in the teaching mode of medical clinical skills, and to provide theoretical and practical basis for finding a better teaching mode to promote the combination of theory and practice.@*Methods@#A total of 172 trainees of clinical skill training in the training center were divided into the control group and the observation group (the observation group was divided into pre-class long-distance group, in-class long-distance group, after-class long-distance group). There were 43 trainees in each group. The control group adopted traditional teaching methods in clinical basic skills courses, and the observation group adopted mixed teaching mode under long-distance education. The satisfaction of teachers and students under the two teaching modes were investigated, and the performance of each group of students in skills, human-computer dialogue, and team first aid comprehensive test were compared.@*Results@#There were significant differences in teacher satisfaction between the control group and the pre-class and in-class distance groups (χ2 = 15.315, P = 0.000). There were significant differences in student satisfaction between the control group and the pre-class and in-class distance groups in terms of interactive participation, liveliness, interesting training skills and teaching level (χ2=4.497-17.153, P = 0.000-0.034). The results of each group reached the expected teaching goals. There were significant differences between the skill test score control group and the pre-class and in-class remote groups (t=25.357, 14.712, all P =0.000). There were significant differences between the human-machine dialogue test control group and the three observation groups (t=14.561, 19.420, 3.821, all P =0.000). There were significant differences between the team emergency comprehensive test control group and the three observation groups (t=14.561, 19.420, 3.821, all P=0.000).@*Conclusions@#Distance education has flexible in the mixed teaching mode of clinical skills, especially in pre-class and in-class. It can rapidly improve the basic clinical skills, theoretical knowledge and team mobilization ability of students. It is one of the best bridges to communicate their clinical theory and practice.
ABSTRACT
Objective To effectually record cardiopulmonary resuscitation (CPR) procedure, analyze and compare the CPR performance of all medical and nursing staffs to find out the existed information for the improvement of the quality of CPR and its survival rate. Methods The medical data were collected according to the Utstein Criteria and CPR event was automatically recorded by a digital video-recording system, by which hands-off times within 10 minutes of CPR and times for installation of chest compression machine, establishment of endotracheal intubation and establishment of the venous channel were analyzed. Multiple regression analysis was conducted to analyze the factors affecting CPR effect. Results ① During the period from December 2009 to December 2015, a total of 376 patients with cardiac arrest (CA) was registered, including 248 males and 128 females, with a median age of 68 (53, 78) years. Estimated median time interval from CA to CPR initiation was 5.0 (0.1, 20.0) minutes and there were 189 cases less than or equal to 5 minutes. The acute myocardial infarction (AMI) with 145 cases (38.6%) was the main etiology of CA. Initial shockable rhythm was found in 16 patients (7.0%) out of 230 out-of-hospital cardiac arrest (OHCA) patients, of whom 13 underwent ventricular fibrillation (5.7%), 3 underwent ventricular tachycardia (1.3%). Initial shockable rhythm was found in 47 patients (32.2%) out of 146 in-hospital cardiac arrest (IHCA) patients, of whom 40 underwent ventricular fibrillation (27.4%), and 7 underwent ventricular tachycardia (4.8%). CPR by a mechanical device (Thumper) was performed in 219 patients (58.2%). In 376 patients, 186 patients had return of spontaneous circulation (ROSC, 49.5%), a successful CPR (ROSC ≥ 24 hours) was found in 110 patients (29.3%), 99 patients was hospitalized alive (26.3%) and 40 patients were discharged alive (10.6%). In 146 cases of IHCA, 89 patients had ROSC (61.0%), a successful CPR was found in 63 patients (43.2%), 56 patients were hospitalized alive (38.4%), and 29 patients were discharged alive (19.9%). In 230 patients of OHCA, 89 patients had ROSC (38.7%), 65 patients received pre-hospital CPR (28.3%), a successful CPR was found in 47 patients (20.4%), 43 patients were hospitalized alive (18.7%), and 11 patients were discharged alive (4.8%). There were 37 patients had a successful CPR (69.8%), and 25 patients were discharged alive (47.2%) in 53 patients with ventricular fibrillation. ② There were 77 patients with valid video information for analysis of CPR performance, with 48 patients of OHCA, and 29 patients of IHCA. Delay median time from the patients presence in the resuscitation room to be placed in rescue bed was 22 (0, 33) seconds. Hands-off median times during 10 minutes of CPR was 41 (18, 90) seconds. Thumper installment median times was 43 (31, 69) seconds. Median time for endotracheal intubation was 59 (35, 109) seconds. Median time of venous catheter placement was 112 (70, 165) seconds. It was shown by multivariate regression analysis that there was a significant correlation between estimated time interval from CA to CPR performed, hands-off time and success rate of CPR (t1 = -3.452, t2 = -2.729), rate of discharge alive (t1 = -2.328, t2 = -2.736, all P < 0.05). In 48 OHCA patients, success rate of CPR was significantly correlated with estimated time interval from collapse to CPR performed (t = -2.409, P = 0.021). In 29 IHCA patients, success rate of CPR and rate of discharge alive was significantly correlated with hands-off times (t1 = -3.412, t2 = -2.536, both P < 0.05). Conclusions Survival to hospital discharge following CA is significantly correlated with the time interval from collapse to CPR performed and hands-off times in CPR. Installment and usage of Thumper should be postponed in order to reduce hands-off times during CPR in IHCA.
ABSTRACT
OBJECTIVE:To compare the sedative effects of dexmedetomidine and midazolam in patients with comprehensive ICU mechanical ventilation. METHODS:74 patients in ICU were randomly divided into dexmedetomidine group (37 cases) and midazolam group (37 cases). Based on mechanical ventilation,dexmedetomidine group received 200 μg Dexmedetomidine injec-tion,dissolving in 48 ml 0.9% Sodium chloride injection,pumped by 1 μg/kg within 30 min,then adjusted to 0.2-0.7 μg/(kg·h) by micropump. Midazolam group received 30 mg Midazolam injection,dissolving in 44 ml 0.9% Sodium chloride injection, pumped by 0.05 mg/kg within 15 min,then adjusted to 0.04-0.20 mg/(kg·h)by micropump. The sedative effects,clinical indica-tors(weaning time,extubation time,time of mechanical ventilation,ICU hospitalization time)and the incidence of adverse reac-tions in 2 groups were observed. RESULTS:There was no significant difference in the sedative effects(P>0.05);weaning time, extubation time,and ICU hospitalization time in dexmedetomidine group were significantly shorter than midazolam group,the dif-ferences were statistically significant(P<0.05);the incidence of total adverse reactions in dexmedetomidine group was significant-ly lower than midazolam group,the difference was statistically significant (P<0.05). CONCLUSIONS:Dexmedetomidine show similar sedative effects with midazolam in patients with comprehensive ICU mechanical ventilation,shorter weaning time,extuba-tion time,ICU hospitalization time,and lower incidence of total adverse reactions than midazolam.
