ABSTRACT
Objective To prepare an occupation well-being scale for nurses, and test its reliability and validity. Methods After literature review and semi-structured interviews, the item pool of the occupation well-being scale for nurses was created based on theory of structure of the subjective well-being. After group discussion, and evaluation by the specialists, a pilot scale was obtained. A total of 350 clinical nurses were selected by using stratified sampling method, and their occupation well-being were surveyed by the scale. The data were used to assess the reliability and validity of the scale. Results The occupation well-being scale for nurses had 3 dimensions, including 8 exploring factors. The values of Cronbach Alpha and the split half reliability coefficient of the total scale, endogenous exogenous satisfaction, satisfaction of nurses occupation happiness were all larger than 0.9, which meaned the internal consistency was good. In the emotion dimension, the value of Cronbach Alpha and the split half reliability coefficient were less than 0.7, which meant the internal consistency was not so good. The reliability coefficient of repeated measurement of the whole scale and each dimension were greater than 0.7, suggesting the external consistency of the scale was good. The content validity index of 3 dimensions were all larger than 0.9,and the cumulative ex-planatory variables were all larger than 55%. Conclusion The occupation well-being scale for nurses proposed in this study has good reliability and validity, and can be used to evaluate the occupation well-being of the nurses.
ABSTRACT
Objective To evaluate the effect of nursing interventions on the quality of life of patients undergoing continuous ambulatory peritoneal dialysis (CAPD).Methods Randomized controlled trials (RCTs) involving nursing interventions were collected from the databases of Cochrane,PubMed,Elsevier Science Direct,VIP,CNKI and WanFang.Data were analyzed with RevMan 5.1 software.Results 8 articles met the inclusion criteria.The results of Meta-analysis showed that there was considerable heterogeneity across the analysis,which might be resulted from length of intervention and patients of different ages according to subgroup analysis,and that gender was not the factor causing heterogeneity.In the experimental group,both physical and emotional aspects after receiving nursing interventions were significantly improved than the control group.Conclusions Nursing interventions can improve the quality of life of patients with CAPD.
ABSTRACT
<p><b>OBJECTIVE</b>To determine the combined effect of hypothermia and crystalloid hemodilution on blood solubility of volatile anesthetics.</p><p><b>METHODS</b>Two hundred and thirty ml blood samples obtained from each of twelve healthy male volunteers were adjusted to a hematocrit of 40% and then diluted with normal saline to hematocrits of 36%, 32%, 28%, 24%, and 20%. Blood/gas partition coefficients of desflurane, sevoflurane, isoflurane, enflurane and halothane were measured at 37 degrees C,33 degrees C, 29 degrees C, 25 degrees C, 21 degrees C and 17 degrees C using a two-stage headspace double equilibration method.</p><p><b>RESULTS</b>As the temperature decreased, the logarithm of the blood/gas partition coefficient increased linearly (P < 0.05). As the hematocrit decreased, the logarithm of the blood/gas partition coefficient decreased linearly (P < 0.05). The combined effect of hypothermia and crystalloid hemodilution on blood solubility of anesthetics was expressed by multiple linear regression equations as follows: Desflurane: log(e)lambda(B/G)=-0.0302 x T+0.0094 x HCT+0.119 R(2)=0.973. Sevoflurane: log(e)lambda(B/G)=-0.0295 x T+0.0092 x HCT+0.306 R(2)=0.961. Isoflurane: log(e)lambda(B/G)=-0.0382 x T+0.0154 x HCT+1.120 R(2)=0.997. Enflurane: log(e)lambda(B/G)=-0.0408 x T+0.0198 x HCT+1.408 R(2)=0.982. Halothane: log(e)lambda(B/G)=-0.0417 x T+0.0218 x HCT+1.649 R(2)=0.994. Where lambda(B/G) is the blood/gas partition coefficient, T is temperature (degrees C) and HCT is hematocrit (%).</p><p><b>CONCLUSIONS</b>Hypothermia increases, while crystalloid hemodilution decreases the blood solubility of volatile anesthetics. The combined effect of hypothermia and hemodilution on blood solubility at any cross point of temperature from 37 degrees C to 17 degrees C and hematocrit from 40% to 20% could be predicted by the multiple linear regression equations developed in this study.</p>

Objective To discuss the feasibility and safety of propofol used in senile patients undergoing minor surgery including gastroscopy and colonoscopy.Methods 40 patients aged 80-88 years old were randomly divided into two groups with 20 cases for each group.Group P received only propofol by intravenous injection in a speed of 1ml/s till eyelash response disappeared.In patients of group F fentanyl was first given at 0.5?g/kg,and 1 minute later,the patients were given propofol by intravenous injection in a same speed as in group P if there was no discomfort until eyelash response disappeared.MAP,HR,SpO2 and RR were determined before induction of anesthesia,beginning of operation,and 1st,3rd and 5th minute after operation.The onset time of anesthesia,total dosage of propofol used,time of palinesthesia and follow-up results were recorded.Results MAP was significantly decreased in both groups at the beginning of operation,and more stable in group F at the 3rd and 5th minute after operation.There were significant differences between two groups in amount of propofol used,and the dosage in group F was less than that used in group P(P

ABSTRACT
Objective To evaluate the influence of different combination of anesthetics on blood pressure (BP) and heart rate (HR) of aged patients with serious illness during operation. Methods Forty patients, aged 80～92, with physical status Ⅱ～Ⅲ as categorized according to American Society of Anesthesiologists (ASA) undergoing selective surgery, were randomly divided equally into two groups: in group A ancsthesia was induced with midazolam, fentanyl and maintained with isoflurane, and in group B anesthesia was induced and maintained with etomidate, sevoflurane and nitrous oxide. Mean arterial pressure (MAP), HR and bispectral index (BIS) were observed at the points of preinduction (T0), induction (T1), intubation (T2), incision (T3), 30 minutes after incision (T4) and extubation (T5). Results After induction, BIS decreased from 95?2 to 52?4, while MAP and HR decreased from 110?11mmHg and 73?8/min to 75?9mmHg and 59?4/min respectively, in group A. While in group B BIS decreased from 94?3 to 58?3, MAP and HR decreased from 103?8 mmHg and 76?6/min to 87?7 mmHg and 67?5/min, respectively. At the point of tracheal intubation, MAP and HR increased significantly in group A compared with group B (P
