RÉSUMÉ
Objective To investigate the effect of laser engraving personalized nasal patch applied to patients with nasal catheter indentation.Methods A total of 124 patients who underwent esophageal cancer surgery in the First Hospital of Lanzhou University from February 2022 to February 2023 and required indwelling nasal catheter were selected as study objects,and were divided into experimental group and control group according to random number table method,with 62 cases in each group.The control group used conventionally cut nasal patches to fix the nasal catheters,and the experimental group used laser engraved personalized nasal patches.Catheter displacement or slippage under the fixation device,nasal patch rolled edges and number of replacement,nasal medical device-related pressure injury,medical adhesive-related skin lesions and patients'comfort were observed in two groups.Results The rate of catheter displacement,number of rolled edges of nasal patches and numbers of replacement in experimental group were significantly lower than those in control group(P<0.05).The incidence of nasal mucosal indentation,nasal pain,nasal pressure injury and medical adhesive related skin lesions in experimental group were significantly lower than those in control group(P<0.05).The comfort of patients at the physiological level of experimental group was significantly better than that of control group(P<0.05).Conclusion Laser engraved personalized nasal patches can reduce the frequency of clinical nasal catheter displacement,nasal patch rolled edges and number of replacement,reduce the occurrence of nasal medical device related pressure injuries and medical adhesive-related skin lesions,and increase patients'comfort.
RÉSUMÉ
Objective: To explore the relationship between left coronary plaque character with the bifurcation angle and diameter by 256-slice CT angiography (CTA). Methods: A total of 387 consecutive patients who received CTA in our hospital were retrospectively studied. There were 102 patients with normal image including 60 male and 42 female at the mean age of (52.10 ± 9.65) years and 285 patients with left coronary plaque including 166 male and 119 female at the mean age of (55.65 ± 10.40) years. All patients were divided into 4 groups according to the plaque condition, Normal group,n=102 patients without plaque, Non-calciifcation group,n=137, Calciifcation group,n=79 and Mixed group,n=69. The patients with non-calciifcation plaque included 73 of mild stenosis and 57 of moderate to severe stenosis in proximal LDA. Left coronary bifurcation angle, proximal diameter and area were measured by multi-planar reconstruction (MPR) and the maximum density projection (MIP) techniques to analyze the relationship between the above indexes and plaque position, character, degree of local stenosis. Results: Left coronary bifurcation angle, the proximal diameter, area in LDA and LCX in 3 plaque groups were all larger than those in Normal group,P0.05, while in patients with moderate to severe stenosis, the bifurcation angle and diameter were larger in male than those in female patients,P<0.05. Conclusion: 256-slice CTA could objectively evaluate left coronary bifurcation angle, stenosis degree and plaque character, which are valuable for coronary artery disease prevention, diagnosis and treatment in clinical practice.
