ABSTRACT
Objective:To explore the management effectiveness of emergency treatment management for emergencies.Methods:To establish precision nursing emergency management system, the response time, triage accuracy, receiving time, information delivery time and rescue success rate were compared before and after the application of the system.Results:After the application of the precision nursing emergency management, the emergency response time was shortened from (6.47±1.25) min to (3.56±1.38) min, and the time for admission and triage reduced from (5.15±0.54) min to (2.84±0.49) min. The time was shortened from (92.45±10.49) minutes to (72.35±13.20) minutes, and the time for information submission was shortened from (121.47±58.41) minutes to (65.23±10.72) minutes; the accuracy of triage diagnosis increased from 96.85% (277/286) to 99.27%(271/273). The rescue success rate increased from 96.15%(275/286) to 98.90%(270/273), and the differences were statistically significant ( t value was -2.920-5.587, χ2 value was 4.220, 4.317, P<0.05). Conclusions:The application of precision nursing emergency management in emergencies can improve the emergency response rate and overall level of nursing staff and ensure the safety of patients.
ABSTRACT
Objective To observe whether or not long-term inhalation of nitrous oxide can affect the cardiac function in rats. Methods Sprague-Dawley rats of either sex were randomly divided into four groups. Group A: inhaled common air for 50 days as control; Group B: inhaled 500mL/L N_2O for 15 days, two hours every day; Group C: inhaled 500mL/L N_2O for 30 days, two hours every day; Group D: inhaled 500mL/L N_2O for 50 days, two hours every day. Float glass intracellular microelectrode recording technique was used for observation of the duration (MAPD_(90), MAPD_(50) and MAPD_(20)) and amplitude of action potentials (APs) of left ventricular muscle cells in vitro. Angiotensin-2 (Ang-2) and eNOS were detected by immunohistochemical technique. Results ① Compared with that in Group A, the Aps duration of left ventricular muscle cells (MAPD) in Group B had no significant change while the MAPDs in Group C and Group D were extended significantly. There were no significant differences among the four groups in Aps amplitude. ② The expression of Ang-2 did not differ significantly between Group B and Group A. The expression level was higher in Group C and D than in Group A. ③ The expression level of eNOS was significantly lower in Group C and D than in Group A (P<0.05). Conclusion Long-term inhalation of N2O can significantly affect the cardiac function in rats, which may be related to higher expression of AngⅡin the heart induced by the long-time excitation of sympathetic nerves.
ABSTRACT
Objective To observe the effects of Pinggan Jiangya Capsule on renin activity (RA) and angiotensinⅡ (AngⅡ) of spontaneously hypertensive rats. Methods Pinggan Jiangya Capsule was administered to male SHRs as treatment group (n=10), and equal volume of normal saline was administered to normal control WKY rats group(n=10) or SHR as model group(n=10) respectively for 12 weeks intragastrically. RA and AngⅡ level were measured by radio-immunoassay. Results The blood pressure decreased significantly after treatment with Pinggan Jiangya Capsule for 12 weeks(P
