Investigation and analysis of occupational physical injuries among healthcare staffs during allopatric medical aid for the fight against COVID-19.

BACKGROUND: Occupational health impairment of medical personnel manifested as a prominent problem in COVID-19. The aim of this study is to investigate the occupational physical injuries of front-line medical staffs in Hubei province during the fight against COVID-19. MATERIAL AND METHODS: questionnaire survey was conducted among 476 medical staffs from 3 regions of Hubei Province, including general characteristics and the physical discomfort/damage suffered in the isolation wards during working hours. RESULTS: A total of 457 valid questionnaires were collected. The common physical discomfort/damage included skin injuries (22.76%), conjunctivitis (15.10%), falls (9.19%), intolerant unwell symptoms (8.53%) and sharp injuries (6.13%). Logistic regression analysis showed that: lack of protective work experience (OR = 2.049, 95% CI: 1.071-3.921), continuous working for 4 h (OR = 3.771, 95% CI: 1.858-7.654), and working >4 h (OR = 7.076, 95% CI: 3.197-15.663) were high-risk factors for skin injuries. Working continuously for 4 h (OR = 3.248, 95% CI: 1.484-7.110) and working >4 h (OR = 3.096, 95% CI: 1.232-7.772) were high-risk factors for conjunctivitis. Lack of protective work experience was a high risk factor for falls (OR = 5.508, 95% CI: 1.299-23.354). The high risk factors for intolerant unwell symptoms were continuous working for 4 h (OR = 5.372, 95% CI: 1.239-23.301) and working >4 h (OR = 8.608, 95% CI: 1.843-40.217). Working in a COVID-19 critical care unit (OR = 3.249, 95% CI: 1.344-7.854) and implementation of nursing (OR = 9.766, 95% CI: 1.307-72.984) were high risk factors for sharp injuries. CONCLUSIONS: Occupational physical injuries are universal in the COVID-19 ward. Those who take up nursing, work in a critical care ward, with no experience in an isolation ward for infectious diseases, and work continuously for ≥4 h on the same day should get more attention.

Time to Occurrence of Phlebitis After Continuous Infusion of Total Nutrient Admixture Through Peripheral Veins: An Experimental Animal Study.

OBJECTIVE: To study the limit time of phlebitis caused by continuous infusion of KabivenTM Pl and TNA (KabivenTM Pl+ alanyl glutamine + potassium aspartate) through a peripheral vein, and to provide a reference for clinical formulation of preventive measures for phlebitis. METHODS: White rabbits (n = 72) were randomly divided into three groups: group A (Normal saline), group B (Kabiven™ Pl), and group C (TNA). Blood was collected from the ear margin vein before administration and after three hours, four hours, five hours, and six hours of administration. CRP and TNF-ɑ were measured by enzyme-linked immunosorbent assay. Hematoxylin and eosin staining and immunohistochemical staining were performed on tissue samples taken from the insertion point of the indwelling needle, the tip of the indwelling needle, and 1 cm from the tip of the indwelling needle, closer to the heart, to analyze early pathological changes in blood vessels. RESULTS: (1) There were no visible inflammatory symptoms in groups A, B, or C within 6 hours. (2) Four hours after starting intravenous administration, the levels of inflammatory markers in groups B and C were higher than in group A, and (3) the degree of inflammatory cell infiltration in groups B and C was more severe than in group A. (4) In all groups, the inflammatory reaction at the tip of the indwelling needle was more severe than at the other two sites. CONCLUSION: When the emulsions TNA and Kabiven™ Pl are infused through a peripheral vein, (1) four hours may be considered as the maximum time for continuous intravenous infusion in the same vein before inflammatory changes become evident, and (2) systematic assessment of the tip of the indwelling needle should be considered for inclusion in the nursing plan for phlebitis monitorings.

Correction to: The application of "upper-body yoga" in elderly patients with acute hip fracture: a prospective, randomized, and single-blind study.

In the original publication of this article [1], there are several errors that need to be corrected as below.

The application of "upper-body yoga" in elderly patients with acute hip fracture: a prospective, randomized, and single-blind study.

PURPOSES: Hip fracture leads to decreased activity and an increased risk of pulmonary complications. The main purpose of this study was to observe the lung capacity, cough capacity of the elderly patient with acute hip fracture, and assess the effects and the feasibility of using a special-designed "upper-body yoga" training to treat elderly patients with hip fracture. METHODS: This was a prospective, randomized, and single-blind study. Eighty-four subjects aged over 65 years were randomly divided into either a control group or a yoga group to undergo an abdominal breathing program or an "upper-body yoga" program until 4 weeks after surgery. The primary outcomes were forced vital capacity/predicted value (FVC%), peak cough flow (PCF), Barthel Index (BI), and the incidence of pneumonia. The secondary outcomes were the rates of right skills and inclination. RESULTS: Thirty-nine subjects in the yoga group and 40 subjects in the control group completed this study. At the end of the first training week, FVC% (74.14% ± 13.11% vs. 70.87% ± 10.46%, P = 0.231) showed no significant difference between the two groups, while the value of PCF (204.80 ± 33.45 L/min vs. 189.06 ± 34.80 L/min, P = 0.048) and BI (38.59 ± 8.66 vs. 33.00 ± 9.32, P = 0.009) in the yoga group was higher. After 4 weeks of treatment, FVC%, PCF, and BI were higher in the yoga group (78.83% ± 13.31 % vs. 72.20% ± 10.53%, P = 0.016; 216.16 ± 39.29 L/min vs. 194.95 ± 31.14 L/min, P = 0.008; 70.77 ± 10.23 vs. 65.75 ± 11.30, P = 0.019). One in the control group and nobody in the yoga group was diagnosed with pneumonia. There was no significant difference between the two groups in terms of the rates of right skills, whereas more elderly people preferred the training program of the "upper-body yoga." CONCLUSION: Elderly patients with acute hip fractures are at risk of impaired lung capacity and inadequate cough. "Upper-body yoga" training may improve the quality of daily life, vital capacity, and cough flow in elderly patients, making it a better choice for bedridden patients with hip fracture.
