ABSTRACT
Objective To investigate the effect of first aid nursing path under the center of chest pain on the diagnosis and treatment of patients with ST-segment elevation myocardial infarction (STEMI). Methods A total of 79 cases of STEMI patients who had been selected for emergency treatment after the establishment of the chest pain center were as the experimental group. The patient's first aid nursing path was used in the center of chest pain. A total of 159 cases of STEMI patients before the establishment of the chest pain center were as the control group, Application of traditional clinical pathway. Compared to the diagnosis and treatment effect of two groups of patients. Results The rate of completed the project within 10 min for the experimental group: the completion of electrocardiogram examination (91.1% vs 84.9% ), oral aspirin, clopidogrel, or lindinda (81.0% vs 75.5%), and laboratory medical order (79.7% vs 69.8%) were higher than those in the control group, and the difference was statistically significant (χ2=2.31, 1.68, 2.06, P < 0.05). The day of hospitalization in the experimental group was less than that of the control group (6.48±3.82 vs 9.76± 4.32), and the difference was statistically significant (t=-9.80, P < 0.05). The mortality rate during hospitalization was lower than that of the control group (5.66% vs 3.8% ), and the difference was statistically significant (χ2=-2.24, P<0.05). Conclusion The first aid nursing path in the center of chest pain can shorten the time of diagnosis and treatment of STEMI patients and improve the diagnosis and treatment effect of STEMI patients.
ABSTRACT
Objective To explore the relationships among nurses’intent to stay,occupational commitment and managers’ leadership styles in emergency department.Methods A total of 130 nurses in emergency department were recruited by convenience sampling method from three tertiary hospitals in Guangzhou.They were investigated by using Nurses’Intent to Stay Questionnaire, Nurses’Occupational Commitment Questionnaire and Multifactor Leadership Questionnaire(MLQ).Results The score of nurses’ intent to stay and occupational commitment were(20?19±3?74)and(76?16±12?13),respectively;both were at medium levels and occupational commitment,transformational leadership style were positively correlated with nurses’intent to stay(P<0?05).Nurses perceived their managers as transformational leaders more often than transactional leaders.Conclusions Both the current nurses’ intent to stay,occupational commitment were at medium levels.The influential factors of nurses’intent to stay in emergency department included emergency work experience,emotional commitment and normative commitment.In order to increase nurses’retention and stabilize the healthy development of nursing personnel,nurse managers should improve the level of nurses’occupational commitment.
ABSTRACT
Objective To analyze the patterns of amino acid changes in liver failure patients treated with non-bioartificial liver support system (ALSS), and to explore the efficacy of ALSS in liver failure treatment. Methods A total of 146 liver failure patients treated with ALSS from June 2009 to August 2010 were recruited in this study. Paired blood samples were collected from every patient and serum amino acids and ammonia were tested by automatic amino acid analyzer. The changes of amino acids in patients with different prognoses, different types/phases of liver failure were evaluated.Measurement data were compared by paired t test. Results After ALSS treatment, liver failure patients experienced a significant decrease in serum glutamic acid and lysine [(395.62±200.24)μmol/Lvs (260. 05±169.56) μmol/L and (436. 73±326. 18)μmol/L vs (407. 12±292.01) μmol/L,respectively; t= 8. 611 and 2. 659, respectively; both P＜0.01)], while experienced greatly increases in threonine and branched-chain amino acids/aromatic amino acid ratio [( 1302. 90 ±1288.70) μmol/L vs (1406.70 ±1272. 34) μmol/L and 1. 23 ± 0. 53 vs 1. 36 ± 0.57, respectively; t = 2. 895 and 1. 061,respectively; both P＜0. 01)]. The changes of glutamic acid, tyrosine, arginine and methionine before and after ALSS treatment in patients with different prognoses, different types/phases of liver failure were all significantly different. Conclusions ALSS treatment could improve the serum amino acid disorder in liver failure patients. The amino acids in patients with different types/phases or different prognoses of liver failure change significantly after ALSS treatment.
ABSTRACT
Objective To study interdialytic body weight gain(IBWG)in maintenance hemodialysis(MHD)patients,and to analyze the associated factors. Methods A total of 269 patients undergoing maintenance hemodialysis were enrolled in this cross-sectional study.The patients were divided into two groups according to the percentage of IBWG(PIBWG:interdialytic body weight gain/dry weight×100%):PIBWG＞3.50%(190 cases)and PIBWG≤3.50%(79 cases).Associated factors of IBWG were analyzed. Results The average IBWG of 269 MHD patients was(2.42±1.01)kg(0-6.33 kg),and PIBWG was(4.25±1.79)%.In male patients,IBWG was (2.45±1.09)kg,and PIBWG was(3.99±1.79)%.In female patients,IBWG was(2.39±0.85)kg,and PIBWG was(4.64±1.74)%which was significantly higher compared to males(P＜0.01).Patients with PIBWG＜3.00%accounted for 20%,with PIBWG≥3.00%to＜5.00%accounted for 50%,with PIBWG≥5.00%accounted for 30%.Compared to patients with PIBWG＞3.50%,those with PIBWG≤3.50%were characterized by elder age(year)(60.50 ±14.49 vs 54.07±13.78),more males(70.88%vs 54.74%),shorter dialysis duration(month)(41.03±41.92 vs 58.83±43.57),larger BMI(kg/m2)(22.67±3.36 vs 20.91±3.25)and less dry weight(kg)(56.69±10.94 vs 62.82±10.97),more residual urine(ml,In)(6.19±0.94 vs 5.48±0.8),lower predialysis serum β2MG(mmol/L)(31.61±9.82 vs 38.54±10.38)and phosphorus(mmol/L)(1.92±0.66 vs 2.15±0.58).Correlation analysis revealed that PIBWG was positively correlated with dialysis duration,Scr,BUN,β2-MG,phosphorus,decrease and decrease percentage of BP during hemodialysis,and negatively correlated with age,dry weight,BMI,residual urine,and pre-dialysis SBP,MAP. Conclusions PIBWG of about 70%of our patients was below 5%.Young.female.low BMI and dry body weight,long dialysis duration,low residual urine,chronic glomerulonephritis and diabetic nephropathy are associated with more IBWG,which may lead to greater intradialytic BP fluctuation.
