ABSTRACT
Objective:To evaluate and summarize the best evidence of energy and protein intake targets and calculation in adult critically ill patients, and to provide evidence-based basis for critical nutrition management.Methods:Evidence related to energy and protein intake targets and calculation of adult critically ill patients, including guideline, expert consensus, systematic review and evidence summary, were systematically searched in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Cochrane Library, UpToDate, BMJ Best Practice, Joanna Briggs Institute (JBI), Web of Science, SinoMed, Medive, China National Knowledge Infrastructure, Wanfang database, VIP database, Guidelines International Network (GIN), National Institute for Health and Care Excellence (NICE), National Guideline Clearinghouse (NGC), Registered Nurses Association of Ontario (RNAO), and Society of Critical Care Medicine (SCCM) from January 2012 to June 2022. Two researchers independently evaluated the quality of the included literatures using the JBI Evidence-based Health Care Center evaluation tool and the Appraisal of Clinical Practice Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), extracted and summarized the best evidence for the nutritional intake goal and calculation of adult critically ill patients, and described the evidence.Results:A total of 18 literatures were included, including 5 clinical guidelines, 8 expert consensus, 3 systematic reviews and 2 evidence summaries. After literature quality evaluation, 18 articles were all enrolled. The evidence was summarized from the four aspects, including energy target calculation method, dose body weight, energy and protein intake target, and calculation method, 24 pieces of the best evidence were finally formed.Conclusions:The best evidence of energy and protein intake targets and calculation for critically ill patients was summarized based on evidence-based. Clinical medical staff can choose indirect calorimetry to calculate energy goals when equipment is available. Patient's height, body weight should be recorded accurately, dose body weight can be determined by body mass index (BMI). Meanwhile, blood urea nitrogen (BUN) loss, fat-free body weight, simple formulas and other methods should be used to continuously evaluate and adjust protein intake targets, to achieve the purpose of optimizing intensive nutrition support.
ABSTRACT
Objective:To observe the effect of goal-oriented management of continuous monitoring of regional cerebral oxygen saturation (rSO 2) on early postoperative neurocognitive disorders (PND) in elderly spinal surgery patients. Methods:From November 2018 to July 2019, 60 patients undergoing posterior lumbar interbody fusion in the Second Hospital of Shanxi Medical University were selected and randomly divided into control group and intervention group, 30 cases in each group. RSO 2 was recorded before anesthesia induction (T 0), 10 min after anesthesia induction (T 1), 10 min after prone position (T 2), 10 min after spinal decompression (T 3), 30 min after spinal decompression (T 4) and 10 min after extubation (T 5); The basic value of rSO 2, the minimum value of rSO 2 (rSO 2min), the average value of rSO 2 (rSO 2mean) and the maximum percentage of decrease of rSO 2 (rSO 2% max) were recorded. When rSO 2 <55% or rSO 2% max >10% and the duration was longer than 15 s, the intervention group took measures such as adjusting head position, adjusting blood pressure, increasing FiO 2 and respiratory parameters, increasing P ETCO 2 until rSO 2 returned to the required range; The control group did not interfere with the intraoperative rSO 2. Neuropsychological tests were used to evaluate the cognitive function of the two groups 7 days after operation. The patients were followed up 30 days after operation with the revised cognitive function telephone questionnaire (TICS-M). The incidence of postoperative neurocognitive impairment (PND) was recorded. The perioperative data and postoperative adverse reactions of the two groups were recorded. Results:At T 3 and T 4, the rSO 2 of the intervention group was significantly higher than that of the control group ( P<0.01), the intraoperative rSO 2min and rSO 2mean of the intervention group were higher than the control group, and the rSO 2%max was lower than the control group ( P<0.05). The incidence of PND 7 days after surgery, extubation time, postanesthesia care unit (PACU) stay time, hospital stay and postoperative adverse reactions in the intervention group were lower than those in the control group ( P<0.05). There was no significant difference in the incidence of PND 30 days after operation between the two groups ( P>0.05). Conclusions:The goal-oriented management of rSO 2 can reduce the incidence of early postoperative PND in elderly spine surgery patients, which is conducive to the rapid recovery of patients after surgery.
ABSTRACT
Objective To explore the relationship between organizational innovation atmosphere and nurses′job satisfaction in China. Methods 300 nurses were sampled during January-February 2018 using convenience sampling method, for a questionnaire survey with the general information questionnaire, nurse organizational innovation atmosphere scale and Minnesota satisfaction scale. Results 282 valid questionnaires were recovered out of 300 questionnaires issued, accounting for 94% of valid recovery rate. The score of organizational innovation atmosphere was 81.35 ± 14.51, and that of job satisfaction was 69.85 ± 14.91, proving a correlation between organizational innovation atmosphere and job satisfaction (P<0.01). A hierarchical regression analysis showed that, with demographic data under control, the regression model can explain 52% of the variance in nurses′ job satisfaction.Conclusions Organizational innovation atmosphere and nurses′ job satisfaction of the hospital are both at a higher level. Good organizational innovation atmosphere contributes to higher job satisfaction of nurses.
ABSTRACT
Through the analysis of current situation of the tension relationship between doctor and patient,this paper expounded that the harmonious management organization theory took the cooperation order as the core of the development of the group organization,and emphasized the running-in process of the internal staffs in the collective group.And it pointed out that the internal cooperation between doctor and patient had the certain cooperation order,and also had obstacles that might cause conflict in cooperation from the perspective of the harmonious management organization theory.This paper analyzed and understood the process of doctor-patient coordination at the group level of harmonious management organization theory,explored and analyzed the obstacles that might cause the conflict during the cooperation process and the reasons in the view of innovation,explored and concluded relevant measures to ease the tension of the doctor-patient relationship,and finally achieved the outcome of maximization of common interests and optimization of treatment effect.
