Integrating medical instruments with medical information systems becomes more and more important in healthcare industry. To make medical instruments without standard communication interface possess the capability of interoperating and sharing information with medical information systems, we developed a medical instrument integration gateway based on Integrating the Healthcare Enterprise Patient Care Device (IHE PCD) integration profiles in this research. The core component is an integration engine which is implemented according to integration profiles and Health Level Seven (HL7) messages defined in IHE PCD. Working with instrument specific Javascripts, the engine transforms medical instrument data into HL7 ORU message. This research enables medical instruments to interoperate and exchange medical data with information systems in a standardized way, and is valuable for medical instrument integration, especially for traditional instruments.
Objective To summarize retrospectively the clinical technology of repairing osteonecrosis of femoral head (ONFH) by free vascularized fibular grafting (FVFG), and the value of modified instruments in operation. Methods Between March 2011 and January 2013, 35 patients with ONFH (47 hips) who underwent FVFG with modified instruments. There were 24 males (32 hips) and 11 females (15 hips), aged 34 years on average (range, 22-43 years). The unilateral hip was involved in 23 cases and the bilateral hips in 12 cases. The disease duration ranged from 5 to 9 months (mean, 7 months). Based on etiology, 25 hips were classified as alcohol ONFH, 12 hips as corticosteroids ONFH, 3 hips as trauma ONFH, and 7 hips as idiopathic ONFH. According to the Association Research Circulation Osseous(ARCO) stage, 3 hips were rated as stage I, 39 hips as stage II, and 5 hips as stage III on the X-ray films. The preoperative Harris score was 58.2±6.1. Results The time to get fibula was 15-35 minutes (mean, 25 minutes). The operation time was 90-200 minutes (mean, 130 minutes), and the blood loss during operation was 150-500 mL (mean, 270 mL). All the patients achieved primary healing of incision, without complication of infection or deep vein thrombosis. All 35 patients were followed up 12-42 months, with an average of 28 months. The Harris score at final follow-up was 87.3±5.7, showing significant difference when compared with preoperative score (t=102.038,P=0.000). Radiographic results at final follow-up showed good position of fibula; and necrosis was improved in 9 hips, had no changes in 36 hips, and aggravated in 2 hips. Conclusion FVFG for ONFH can improve hip function effectively, and modified instruments can improve operation efficiency.
Objective Compare and analyze the value of β-hydroxybutyrate from two kinds of blood ketone instruments (Optium Xceed blood ketone body instrument from American Abbott laboratories and TBS-1 blood ketone body instrument from Beijing Yicheng company), and provide instructions for clinical applications. Methods Select 7 children patients with epilepsy which have a response to ketogenic diet. The two kinds of blood ketone instruments were used to test blood ketone value of whole blood synchronously in five different periods, and compare the 70 results. Results The measuring results obtained from these two kinds of blood ketone body instruments have statistical difference significantly. The value acquired from TBS-1 blood ketone body instrument is lower than that from Optium Xceed blood ketone body instrument. Measurements using a paired t test, the value of t=12.14, P<0.01. The results from two kinds of blood ketone body instruments are statistically significant. Conclusion The values from 2 kinds of blood ketone instruments are different, which would influence the clinical judgment. At present, the key problem is that there is lack of special blood ketone measure technology for patients with ketogenic diet. How to improve the measure accuracy of high-level blood ketone value remains the future work.
In order to promote the implementation of the three standards of central sterile supply department (CSSD), new standards for cleaning and disinfection/sterilization of flexible endoscope, dental instruments, and environmental surface in healthcare, this article elaborates about central management of CSSD; management of loaners and implants; technique of autoclave sterilization, ethylene oxide sterilization, and hydrogen peroxide sterilization; high level disinfection or sterilization of flexible endoscope; disinfection and sterilization of dental instruments; daily and enhanced cleaning and disinfection of environmental surface in healthcare facilities. This could help clinical healthcare workers to implement these new standards, effectively prevent nosocomical infection, and guarantee the personal safety of patients.
Objective To evaluate the advantages about video-assisted thoracoscopic surgery (VATS) lobectomy with optimized management of surgical instruments package. Methods A total of 200 patients with lung cancer were enrolled, which included 78 males and 122 females, aged 24-83 years at median age of 56.8 years. All of them were divided into 2 groups including a routine group (n=100) and an optimized management of surgical instruments group (n=100). The total operation time, bleeding, instrument weights, utilization rate of instruments, counted and cleaning time in 2 groups were recorded and analyzed. Results The average operation time and average lost blood of the routine group was 117.62±42.52 min and 53.14±50.69 ml, respectively, and the one of the optimized instruments group was 120.48±40.62 min, 56.10±49.87 ml, respectively, with no significant difference between the two groups (P=0.112, P=0.231, respectively). The utilization rate of instruments in the routine group (58.02%±2.39%) was significantly lower than that of the optimized instruments group (94.00%±1.48%, P=0.014). The counted time, the loading and unloading time and the cleaning time of instruments in the routine group was 112.00±26.00 s, 70.00±15.00 s, 1 010.00±130.00 s, respectively, much longer than the time of the optimized instruments group, which was 65.00±23.00 s, 20.00±4.00 s, 665.00±69.00 s, respectively. There was a statistical difference between the two groups (P=0.028, P=0.011, P=0.039, respectively). The value of instruments in the routine group (177 574.00±14 438.00 yuan) was apparently higher than that of the optimized instruments group(132 027.00±10 311.00 yuan), with a statistical difference (P=0.032). Conclusion It is demonstrated that optimized management of surgical instruments package in VATS lobectomy can greatly improve the utilization rate of instruments and work efficiency, with no effects on the operation time and amount of bleeding in lobectomy.
ObjectiveTo investigate the operation of transcatheter aortic valve replacement (TAVR), the use of TAVR instruments and the current situation of TAVR-related nursing in our country, to reveal the characteristics of TAVR in various hospitals in our country, and to provide reference data for improving perioperative nursing and industry development of TAVR. MethodsA questionnaire survey was conducted among the head nurses of the cardiac catheterization laboratories of 51 hospitals in China that carried out TAVR operations, with a total of 5 items and 23 questions. The current situation of TAVR operation methods, intraoperative instruments and nursing care in China were analyzed. ResultsThe number of hospitals in China which started conducting TAVR and the beginning year were: 2 in 2010, 1 in 2012, 1 in 2013, 1 in 2015, 11 in 2016, 13 in 2017, 15 in 2018 and 7 in 2019; the number of transfemoral TAVR in 2019: 32 (62.75%) hospitals conducted on less than 20 patients, 7 (13.73%) hospitals 20-<50 patients, 6 (11.76%) hospitals 50-100 patients and 6 (11.76%) hospitals more than 100 patients; TAVR strategies adopted by most hospitals were: general anesthesia (90.20%), the use of vascular sealers (80.39%), backing by cardiac surgeon (74.51%) and using homemade prosthetic valves. Conclusion At present, the number of TAVR carried out in Chinese hospitals is still far behind that of developed countries in Europe and the United States. Our country has adopted the form of multidisciplinary cardiac team cooperation and formed a TAVR nursing model with Chinese characteristics.
