Objective?To explore the safety of hydrophilic fiber containing silver dressings used on the wound of the patient with pressure sore. Methods?From January 2014 to January 2017, 60 elderly patients with pressure sore from inpatient and outpatient of Geriatrics Department of Shenzhen People's Hospital were selected as the research object. They were divided randomly into control group and experimental group, 30 patients for each group. Patients in the experimental group used hydrophilic fiber containing silver dressings on half of the area of the wound. Patients in the control group used hydrophilic fiber containing silver dressings on the whole area of the wound. All the treatment lasted for 4 weeks. Silver concentration of serum, serum creatinine and alanine aminotransferase value were detected in two groups of patients. Data were analyzed by SPSS 17.0 statistical software. Results?After the use of hydrophilic fibers containing silver dressing, the silver concentration of serum in the two groups increased, the value reached a peak in the third week and a downtrend in the fourth week; There were no significant differences in silver concentration of serum between the two groups in the first 3 weeks (P＞ 0.05), but the difference was statistically significant only in the fourth week (P＜ 0.05). There were no significant differences between the serum creatinine and alanine transaminase in the two groups (P＞0.05). Conclusions?The usage of hydrophilic fibers containing silver dressing cannot directly affect serum creatinine and alanine transaminase within four weeks.

Objective:To understand intensive care unit(ICU)doctors'opinions and suggestions on implementing palliative care,and provides a reference basis for the implementation of palliative care in Chinese ICU.Methods:A purposive sampling technique was used to conduct one-on-one semi-structured interviews with 11 ICU doctors.Colaizzi's phenomenological analysis method was utilized to code,classify,interpret,and comprehensively analyze the interview data.Results:A total of 4 themes and 18 sub-themes was extracted,including cognitive biases toward palliative care,the belief that implementing palliative care in the ICU has significant humanistic implications(palliative care practice is the most perfect embodiment of medical humanities,palliative care in the ICU can alleviate patient pain and reduce invasive operations,palliative care can achieve comfortable care for ICU patients,palliative care focuses on maintaining the dignity of ICU patients,palliative care can pay attention to the inner voice of ICU patients,and implementing palliative care will help to more effectively allocate resources),difficulties faced by ICU in carrying out palliative care(lack of clarity in relevant policies at the legal level,closed management environment in the ICU,insufficient manpower in the ICU and lack of palliative care professional team,inadequate understanding of ICU patients'families,lack of death education,not included in medical insurance payments,and lack of communication skills of young doctors),strategies to promote the development of palliative care in the ICU(ICU palliative care can be piloted first,the development of ICU palliative care screening tools will help with the development of palliative care,the palliative environment and the handling of death procedures can be further optimized,and the application and implementation of scientific methods to shorten the gap between evidence and practice of palliative care).Conclusions:The integration of palliative care and ICU in China is still blank.The significance of implementing palliative care in ICU should be emphasized,ICU doctors'knowledge and skills of palliative care should be improved from multiple perspectives,patient preference should be emphasized to improve the knowledge and acceptance of palliative care of ICU patients'families,and the promotion of palliative care in ICU clinical practice should be pioneered and piloted.
