ABSTRACT
Objective:To compare the accuracy of the needle tip reaching the target tissue between two subcutaneous injection techniques under ultrasound imaging in order to provide a basis for clinical injection to make a safe and reasonable decision.Methods:This was a parallel controlled non-inferiority comparative study. A total of 68 patients who received subcutaneous injections in the outpatient injection room of Nanjing Drum Tower Hospital Affiliated to Nanjing University from June 2021 to September 2022 were selected as the research subjects, and they were divided intothe A and B group according to the random number table method, there were 34 cases in each group. Group A received pinched skin injections, and group B received taut skin injections. Unify the injection site, injection needle length, and needle insertion angle. The accuracy rate of the needle tip reaching the target tissue, namely the subcutaneous fat layer, was compared between the two groups by ultrasound imaging, and the pain scores and the imaging performance during the injection process were observed.Results:The accuracy of the needle tip reaching the subcutaneous fat layer in the group A was 97.1%(33/34), which compared with the 100.0%(34/34) in the group B, there was no significant difference ( χ2 = 0.53, P>0.05). There was no significant difference about the distribution of pain scores between the two groups ( χ2 = 0.67, P>0.05). There were no significant differences about age, subcutaneous fat thickness and the distance from the needle tip to the myofascial in patients with different pain scores ( F = 1.20, 0.44, H = 0.64, all P>0.05). Conclusions:Under certain conditions, pinching the skin and tightening the skin have the same accuracy and safety when the needle tip reaches the subcutaneous fat layer of the target tissue, and the choice should be made according to the clinical situation. Imaging observations have enlightening significance for the practice of subcutaneous injection.
ABSTRACT
Objective To understand the influence of nursing home service experience on humanistic caring ability of nurses.Methods Using the phenomenological method,15 clinical nurses after participation of nursing home service were interviewed,and the data were analyzed using 7 step Colaizzi method.Results 3 themes were extracted:service experience,the understanding of humanistic nursing care,influence of service experience on humanistic caring ability of nursing.Conclusions The participation of nurses in the nursing home services can promote the humanistic caring ability of nursing,which is a positive way of cultivating the ability of humanistic care ability.
