the technical solution of the present invention is further described with reference to the following specific examples.
Clinical application observation:
the novel orthopedic external fixation needle path nursing material is used for local exudation culture of bacteria and conventional disinfection, and does not use novel materials to treat wounds, and the comparison of the types and time limits of bacteria produced by exudate culture and the comparison of the amount of exudate are carried out.
(1) Subject selection: patients with diabetes, malignant tumor, severe blood infectious diseases, long-term bed rest, poor local soft tissue condition, local skin diseases, and systemic infection are excluded from the age below 65 years. The above subjects perfected the relevant procedures under the condition of soliciting their consent without violating medical ethics.
(2) The clinical application operation flow comprises the following steps: all patients perform standard operation, the fixing needles or screws are firm and are not loosened, after operation, the operation lasts for 24-48 h, after disinfection of conventional hands, a control group is dipped with ethanol by a cotton swab, the skin at the local part of a needle channel and around the needle channel is disinfected and cleaned for 2 times/day, and wounds are still wrapped by a sterile external dressing in a conventional mode; cleaning the skin of the local part of the needle channel and the periphery of the needle channel with normal saline, opening the adhesive film after drying, removing the release paper with the adhesive surface, aligning the center of the functional pad with the needle channel, annularly wrapping the functional pad around the needle channel into a tower shape by taking the fixed needle as the center, covering the dressing on the skin downwards, overlapping two ends of the opening of the dressing, removing the release paper with the back surface, and firmly adhering the periphery and the bottom. The two groups take exudates for culture at 1 day, 1 week, 2 weeks, 4 weeks and 6 weeks after operation, and the application of the control group is changed for 1 time every 5-7 days. After discharge, the responsible nurse visits 1 time per week, and if abnormal, the responsible nurse comes to the hospital in time. Two groups of bacteria culture, needle tract infection, needle tract pain, blood leakage around the needle tract and patient satisfaction conditions are compared.
(3) Operation and therapeutic effect determination standard:
bacterial culture: and (3) strictly executing a sterile operation principle for specimen collection, reserving secretion at a needle passage for bacterial culture, observing and judging according to a culture result, and executing the operation according to national clinical examination operating regulations (5 th edition) (people health publishing agency).
② infection of needle tract: the international Checketts-Otterburns infection grading system standard is adopted, and the specific judgment standard is as follows:
degree I: redness around the needle track;
II degree: the red swelling and pain around the infected needle track are obvious;
and (3) III degree: there are oozing, pus flowing out and necrosis around the needle channel.
And (3) observing time limit: the external fixation bracket is removed after operation until the external fixation is removed. Infection occurred in 1 needle tract, which is a positive case of needle tract infection. The incidence of infection was the percentage of positive needle tracks to the total number of needle tracks in the group.
③ pain in the needle tract: the degree of pain is numerically expressed by 0 to 10 using Numerical Rating Scale (NRS). The degree of pain of different degrees is indicated, 0 is no pain; 1-3 are mild pain (no effect on sleep); 4-6 are moderate pain; 7-9 are severe pain (inability to sleep or sleep interruption); 10 is severe pain. The wound exudate is obtained by subtracting the weight before dressing change from the weight of the dressing after dressing change;
fourthly, the satisfaction of the patient: the 'satisfaction questionnaire' is designed by self, and is divided into very satisfactory, general and unsatisfactory, wherein the satisfaction is (very satisfactory + satisfactory)/total case number x 100%. Statistical methods statistical analysis of the data was performed using SPSS13.0 statistical software. The measurement data is expressed by mean number + -standard deviation (-x + -s), and t test is adopted; the counting data were examined by X2. P <0.05 indicates that the difference is statistically significant, and thus the therapeutic effect is judged according to the final result.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
