Value of Emergency Nursing Procedures in Improving the First Aid Efficiency and Outcomes of Comatose Patients with Cerebral Hemorrhage

Objective:To determine the application value of emergency nursing in improving the efficiency and outcomes of first aid for comatose patients with cerebral hemorrhage.Methods:Forty comatose patients with cerebral hemorrhage treated in Suzhou Hospital of Traditional Chinese Medicine from August 2018 to June 2019 were selected as the research subjects in this study;the patients were divided into two groups,a control group and a study group,by lot;the patients in the control group received nursing by conventional means,while emergency nursing procedures were provided to the patients in the study group;the efficiency of first aid and the outcomes of the two groups were compared;the application value of emergency nursing procedures was analyzed.Results:The first aid efficiency of the study group was significantly higher than that of the control group;the condition evaluation,reception time,triage time,and rescue time of the study group were significantly lower than those of the control group;the treatment outcomes of the study group were significantly better than those of the control group(P<0.05).Conclusion:Based on the results,compared with conventional nursing methods,the implementation of emergency nursing procedures for comatose patients with cerebral hemorrhage helps to improve the efficiency of first aid and the outcomes of the treatment;it has high clinical application value and is worthy of popularization as well as application in clinical practice.

Status of Severe Accident Management Guidelines at Kozloduy Nuclear Power Plant

The objective of this paper is to present the current organization of the Emergency Procedures including Emergency Operating Procedures (EOP) and Severe Accident Management Guidelines (SAMG) in Kozloduy Nuclear Power Plant (KNPP) as a function of the severity of the accident conditions. Special attention is paid to SAMG. It is described when the SAMG are used and at which conditions in a transition between the EOPs and the SAMG should be made. The Critical Safety Function Restoration Guidelines and their connections with SAMGs and EOPs are also discussed. The arrangement of SAMG is described in detail, since in the KNPP exist 2 types of SAMGs for Main Control Room (MCR) and for the Accident Management Centre (AMC) and they contain the same strategies, but they are different in format. Both types are symptom oriented procedures, but those for MCR are in 2-column-format with interconnections, whereas those for the AMC are developed in a logical manner and simplified for people, who take decisions. In the paper, they are also discussed the adopted strategies in existing SAMG that should be followed to recover from a damaged core condition and to prevent or mitigate the release of fission products. In the paper, they are also described a number of technical measures for management and mitigation of severe accidents, which are implemented in KNPP before and after the Fukushima accident. Many of them are common for WWER-1000 type of reactors, but some of them are unique and plant specific. This information can be useful for operators of other WWER type reactors or even PWR reactors.

Analysis of the Presence of Vapor in Residual Heat Removal System in Modes 314 Loss-of-Coolant Accident Conditions Using RELAP5

The Westinghouse Nuclear Safety Advisory Letter NSAL-09-8 investigated the possibility of presence of vapor in RHR （residual heat removal） system in modes 3/4 LOCA （loss-of-coolant accident） conditions. This concerns the Westinghouse standard three-loops plant for which the RHR is the low pressure part of the St （safety injection）. In some cases one or both RHR trains may become inoperable for SI function. As a response to this letter, Westinghouse Electric Belgium is providing RELAP5 analyzes for Westinghouse NSSS （nuclear steam supply system） European plants to assess the thermal hydraulic behavior of the RHR suction piping system for ECCS （emergency core cooling system） initiation events postulated to occur during startup/shutdown operations. Several concerns including condensation induced water hammer and voiding at the RHR pump have been investigated. As a conclusion, the analysis allowed to define the bounding hot leg temperature conditions under which both RHR trains remain safely operable. These bounding conditions are then implemented by the customer in their OPs （operating procedures） to achieve safe operations and successful accident management.
