BACKGROUND: This multicenter cross-sectional study sought to determine the knowledge, attitudes, and practices regarding the use of physical restraints by Chinese nurses in intensive care units (ICUs) of tertiary hospitals. METHOD: A scale technique was used to measure the knowledge, attitudes, and practices of 383 RNs from eight tertiary hospitals in Chongqing, China. RESULTS: A total of 383 valid questionnaires were returned, for a response rate of 89.49%. Approximately 8.1% of the nurses were male, 67.1% had a bachelor's degree or above, and 55.09% were ICU specialists. The average age was 28.62 years (SD = 4.56). The mean scores were 74.33 of 111 (SD = 9.552), 24.41 of 40 (SD = 4.872), and 65.66 of 130 (SD = 20.880) regarding knowledge, attitudes, and nursing practices, respectively. For the attitude scale, the scores of nurses who were certified ICU specialists and had extensive working experience were higher than those with less experience; the difference was statistically significant (p < .05). CONCLUSION: Results indicated that nurses employed in the ICUs of tertiary hospitals in Chongqing, China, have relatively insufficient knowledge, comparatively incorrect attitudes, and unreasonable means of practicing physical restraint. Continuing education should focus strongly on the relationship between physical restraint and unplanned extubation, and guidelines on physical restraint urgently need to be developed.

It is an efficient and effective ecological restoration method by using the adaptability, large biomass of aquatic plants to purify the polluted water at present. However, there is a lack of systematic research on the impact on the physiological ecology of aquatic plants and its environmental effects of algae blooms cluster in summer. The aim of this paper is to reveal the mechanism of macrophytes demise in a shallow ecosystem by studying the influence on photosynthesis of water hyacinth caused by the cynaobacterial blooms gathered, and also to provide the theoretical basis for full effects of purification function of macrophytes to reduce the negative effects on the aquatic plants after algae blooms gathered during the higher temperature (not lower 25 degrees C) through simulating experiments. Results showed the dissolved oxygen quickly consumed in root zone of aquatic plants after algae blooms gathered and showed a lack of oxygen (DO < 0.2 mg x L(-1)); and the ORP was lower than -100 mV after 1 d, and it declined to -200 mV at the end of the experiment, and pH declined 0. 7unit compared with that of control group ( CK). There were lots of nutrients releasing to the water after the algae cell died and the NH4+ -N concentration was 102 times higher than that of the control group root zone. And the macrophytes photosynthesis reduced quickly and the plant body damaged with the intimidation of higher NH4+ -N concentration (average content was 45.6 mg x L(-1)) and hypoxia after algae cell decomposed. The average net photosynthesis rate, leaf transpiration rate were 0.6 times, 0.55 times of the control group, and they reduced to 3.96 micromol x (m2 x s)(-1), 1.38 mmol x (m2 x s)(-1), respectively. At the end of the experiment, they were 22.0 micromol x (m2 x s)(-1) and 7.61 mmol x (m2 x s)(-1) for the control group. Results also showed the algae bloom together had the irreversible damage to the aquatic plants. So in the practice of ecological restoration, it should avoid the harm to the plant after the algae bloom cells gathered and decomposed so as to play the purification function of the plant in the ecological rehabilitation project.
