目的:探究两种无创正压通气在新生儿呼吸窘迫综合征治疗中的应用价值。方法:以2016年1月-2018年1月河源市妇幼保健院新生儿科收治的符合入选标准的80例呼吸窘迫综合征(NRDS)早产儿为研究对象,采用随机数字表法分成研究组与对照组,各40例。研究组给予经鼻导管高流量加温湿化正压通气(HHFNC),对照组给予鼻持续正压通气(NCPAP),比较两组的治疗效果。结果:研究组患儿开奶时间、总用氧时间和达到全肠道喂养时间均较对照组缩短,差异均有统计学意义(P<0.05)。两组总辅助通气时间、无创辅助通气时间比较,差异均无统计学意义(P>0.05)。研究组治疗期间气漏、腹胀及鼻部损伤等相关并发症发生率均低于对照组,差异均有统计学意义(P<0.05),两组NEC、BPD、ROP、颅内出血、PDA的发生率比较,差异均无统计学意义(P>0.05)。结论:对于早产RDS患儿来说,在无创通气模式的选择中,使用HHFNC后患儿腹胀情况明显减少,且患儿鼻损伤明显好转,用氧时间出现一定减少,开奶时间得到提前,未延长无创辅助通气时间。 相似文献

The zebra mussel (Dreissena polymorpha) is a notorious freshwater biofouling pest, and populations of the species can alter aquatic environments through their substantial filtration capabilities. Despite the ecological importance of zebra mussel filtration, many predictions of their large-scale effects on ecosystems rely on extrapolations from filtration rates obtained in static laboratory experiments, not accounting for natural mussel densities, boundary layer effects, flow rates or elevated algal concentrations. This study used large-scale industrial flume trials to investigate the influence of these factors on zebra mussel filtration and proposes some novel industrial applications of these findings. The flume trials revealed some of the highest zebra mussel clearance rates found to date, up to 574+/-20mlh(-1)g(-1) of wet tissue mass. Under low algal concentrations, chlorophyll a removal by zebra mussels was not proportional to mussel density, indicating that field rates of zebra mussel grazing may be much lower than previous studies have predicted. Increasing ambient velocities up to 100mls(-1) ( approximately 4cms(-1)) led to increased clearance rates by zebra mussels, possibly due to the replenishment of locally depleted resources, but higher velocities of 300mls(-1) (12cms(-1)) did not lead to further significant increases in clearance rate. When additional algal cultures were dosed into the flumes, chlorophyll a removal increased approximately logarithmically with zebra mussel density and there were no differences in the clearance of three different species of alga: Ankyra judayi, Pandorina morum and Cyclotella meneghinia. Some novel industrial uses of these zebra mussel filtration studies are proposed, such as: (1) helping to inform models that predict the large-scale grazing effects of the mussels, (2) allowing estimates of zebra mussel densities in industrial pipelines, and (3) constructing large-scale biofilters for use in water clarification. 相似文献

Zebra mussels, first discovered in the Great Lakes in 1988, have frequently been detected in fire protection systems. However, the potential for large-scale infestations has not been established. It is clear that even small numbers of mussels can cause problems in areas that have small-diameter piping or in sprinkler system nozzles, if shells are flushed down-stream during emergency use.This paper will discuss the development of a method of zebra mussel control that limited interference with normal system operations when used at Niagara Mohawk's Dunkirk Steam Station. Because oxygen is often depressed in these systems and limits mussels survival and growth, it was established that by monitoring oxygen alone, or in combination with veliger or mussel larval monitoring, high-risk areas for mussel infestation could be determined. In previous laboratory research, it had already been determined that concentrations of potassium in excess of 100 mg/L would lead to quick mortality in adult zebra mussels. These results, along with a biofouling risk assessment completed at Dunkirk Steam Station, were used to develop and implement a successful treatment of the high-risk areas in the plant's fire protection water systems using potassium in the form of potash as the controlling agent. 相似文献

Though zebra mussels, first discovered in the Great Lakes in 1988, have frequently been detected in fire protection systems, the potential for large-scale infestations and blockage has not been established. It is clear, however, that even small numbers of mussels can cause problems in areas with small-diameter piping or in sprinkler system spray heads or nozzles. A method developed to determine the risk of mussel infestation within fire protection systems was implemented without interfering with system operation. The complexity of fire protection systems makes it useful to determine low-risk areas where remediation is not necessary, as well as high-risk areas where infestation is likely, allowing treatment at a greatly reduced effort, cost, and impairment of these protection systems.A method was developed to sample representative oxygen levels in fire protection water systems in areas within Niagara Mohawk's Dunkirk Steam Station, while maintaining system pressure and operability. The systems were then assessed in terms of low risk (0 to 2 ppm), medium risk (2 to 4 ppm), and high risk (more than 4 ppm) based on criteria previously developed in the laboratory. Based on the findings presented in this paper, specific high-risk areas within Dunkirk Steam Station were later treated experimentally, and long-term strategies to eliminate and control mussels in the fire protection water were established. These methodologies may be useful in assessing other sites. 相似文献
