Abstract:

Relevance. Despite many techniques for reducing intraocular pressure, surgical treatment of glaucoma has limited effectiveness. First, due to excessive scarring of new intraocular fluid outflow pathways and second, antifibrotics medicaments are unable to effectively control wound healing. The use of drainages reduces the risk of excessive scarring in the area of the filtration pad and forms several ways of outflow of intraocular fluid. The review presents the following sections: development history, advantages, disadvantages, surgical technique and promising directions of glaucoma drainage surgery. Purpose. Summarizing data on the possibility of drainage surgery, historical aspects, causes of scarring and methods of dealing with them. Provide data on various modern drainage devices that are used not only in Russia and their effectiveness. Material and methods. To perform the review, we searched for literature sources on the abstract databases E-library, PubMed and Scopus for the period up to and including 2018, using the keywords «glaucoma drainage surgery» (in the E-library database), «anti-glaucoma drainage» and «anti-glaucoma drainage device» (in the PubMed and Scopus databases). Abstracts of conferences were excluded from the review. A total of 40 articles related to the review topic were identified. The beginning of publications on this issue in domestic sources dates back to 1970, and in foreign sources to 1987. Results. The review presents the history of development, advantages, disadvantages of surgical techniques and promising areas of glaucoma drainage surgery. Various models of drainage devices, as well as their specific and non-specific complications are described. The effectivenes of various valves were 70%, with an average decrease in the level of IOP by at least 50% from the preoperative values. At the same time, the risk of an increase in the level of IOP above the target values is about 10% per year, which leads to the fact that after 5 years only in 50% of cases drainage devices function effectively. Therefore, studies of biomaterials, forms and techniques of drainage implantation surgery, new controlled-release antifibrotic drugs can positively affect the long-term effectiveness of glaucoma surgery. Conclusion. The data presented in the literature review allow us to identify the most effective models of drainage devices, their effectiveness, implantation techniques and possible complications. Key words: glaucoma, refractory glaucoma, glaucoma drainage surgery, drainages.

Abstract:

AbstractPlacement of a chest tube drains intrapleural fluid and air. The tube should be attached to a drainage system, such as one-, two-, or three-compartment devices, a one-way (Heimlich) valve for ambulatory drainage, a digital system, or a vacuum bottle. The frequently employed three-compartment systems, currently integrated disposable units, allow adjustment of negative pressure or no suction (water seal), and include an air leak meter on the water seal chamber to be used for demonstrating and quantifying air leak. These readings are subjective and prone to interobserver variability. Digital pleural drainage systems offer the benefits of quantification of any air leak and pleural pressure. Indwelling pleural catheters, typically utilized for malignant pleural effusion, can be drained using vacuum bottles. Knowledge of the design and functionality of each device in the setting of an individual patient's specific pleural process facilitates the selection of practical and financially prudent chest tube drainage strategies.

Abstract:

Patients with a keratoprosthesis often develop complications including glaucoma, requiring glaucoma drainage devices. In most of these patients, glaucoma drainage devices have been shown to be safe and effective. However, occasionally, a glaucoma drainage device in the setting of a keratoprosthesis can lead to conjunctival erosion with mechanical trauma. While repeat surgical intervention may appear necessary, we report a case of a patient who had improved conjunctival erosion and glaucoma drainage device exposure after refitting of a therapeutic contact lens. Therapeutic contact lenses can be used to maintain hydration and decrease exposure while improving cosmesis and refractive error. Complications following keratoprosthesis surgery are an understudied area, particularly regarding glaucoma drainage devices, and we seek to show that careful fitting of therapeutic contact lenses may avoid the risks of repeat surgical intervention.

Abstract:

Abstract The article presents technical aspects of maintenance of proper condition of drainage devices of public roads, and municipal and district roads in particular. The importance of road drainage is discussed, basic surface drainage devices discussed together with their location within the road. With use of actual examples we indicated the typical errors made during repairs and overhauls of the road, that have the consequence of disrupted continuity of drainage or the risk of quick loss of functions of drainage devices. The results of survey of technical condition of roadsides and the drainage device within a selected rural municipality were presented, indicating main problems of road keepers connected with keeping the drainage infrastructure in appropriate condition. The need of growing awareness in planning and designing road investment was indicated in the field of consequences of performing insufficient drainage.

Abstract:

Programmable shunt valves are commonly used devices for the treatment of hydrocephalus. Unlike fixed shunt valves, programmable devices allow the operator to alter the amount of CSF drainage without the need for shunt revision or valve replacement. With their increased use, many different programmable shunt valves have been developed by various manufacturers; each programmable shunt valve has a distinct radiographic appearance and CSF drainage setting. Because of potential interactions with MR imaging scanners, which can alter programmable shunt valve function, understanding and accurately reporting these devices is essential.Learning Objectives: Identify commonly used programmable shunt valves and understand their CSF drainage settings to enable the detection of device alterations after MR imaging scanning.

Abstract:

AbstractGlaucoma is the leading cause of irreversible blindness worldwide. An increased intraocular pressure (IOP) is known as major risk factor. Currently, drainage devices that are implanted by means of minimally invasive glaucoma surgery (MIGS) represent a promising approach for IOP low-ering. Commercially available devices for MIGS suffer from unregulated drainage involving ocular hypotony. Further-more, long term drainage capability of current devices is limited by fibrotic encapsulation processes. Therefore, our group focusses on the development of a valved drug-eluting microstent for MIGS. Within the current work, we developed two alternative injector devices for minimally invasive mi-crostent implantation. Both injector devices were based on a cannula in which the microstent is loaded and a mandrel inside the cannula. Injector device A is designed to push the microstent out of the cannula and injector device B is de-signed to withdraw the cannula above the microstent. Manu-facturing of injector devices was conducted using rapid prototyping. Simplified polymeric microstents were manu-factured from polycarbonate based silicone elastomer. Simulated use was performed in a silicone eye model. The presented injector devices were suitable for minimally in-vasive ab interno microstent implantation into suprachoroidal space. Ongoing miniaturization of the microstent system will allow the use of a 22 G cannula in future ex vivo experiments.

Abstract:

All nurses who care for patients with LDDs must have demonstrated initial competency with LDDs and should participate in periodic in-service training to maintain that competency. Clearly an educated critical care nurse is the most essential partner that a patient with an LDD can have for preventing complications and ensuring that the best outcomes for the patient are achieved. Nurses caring for patients with an LDD must have a clear institution-specific policy and procedure available to guide the care of these patients.

Abstract:

Hydrocephalus is a pathophysiology due to the excess of cerebrospinal fluid in the brain ventricles and it can be caused by congenital defects, brain abnormalities, tumors, inflammations, infections, intracranial hemorrhage and others. Hydrocephalus can be followed by significant rise of intraventricular pressure due to the excess of production of cerebrospinalfluid over the absorption, resulting in a weakening of intellectual functions, serious neurological damage (decreased movement, sensation and functions), critical physical disabilities and even death. A procedure for treatment involves the placement of a ventricular catheter into the cerebral ventricles to divert/drain the cerebrospinal fluid flow to a bag outside of the patient body – provisory treatment known as external ventricular drainage (EVD). Another option is the permanent treatment, internal ventricular drainage (IVD), promoting the cerebrospinal fluid drainage to other body cavity, being more commonly the abdominal cavity. In both cases, EVD and IVD, it is necessary to use of some type of neurological valve in order to control the flow of cerebrospinal fluid. In the present work is proposed an experimental procedure to test the hydrodynamic behavior of a complete drainage system, or parts of them, in order to verify its performance when subjected to pressure gradients found in the human body. Results show that the method is well adapted to quantify the pressure drop in neurological systems.

Abstract:

Glaucoma is a socially sensitive disease, being one of the leading causes of irreversible visual impairment and blindness. Refractory glaucoma is one of the most severe forms of the disease as it is resistant to conservative and surgical methods of treatment. Because of pronounced postoperative fibroblastic activity of eye tissues, leading to gross scarring and obliteration of outflow paths, modern materials and methods of drainage surgery are needed. The review presents a variety of drains used today and considers in detail their main characteristics and the biocompatibility of the material used with eye tissues. Various groups of implants are presented, whose effectiveness and safety are compared and assessed. The statistics of postoperative complications and long-term results of surgical treatment are given.

Abstract:

Purpose The purpose of this paper is to compare the fluid dynamic performance of two Aqueous Humor (AH) ocular drainage devices, the SOLX® Gold Micro Shunt (GMS) and the novel Silicon Shunt Device (SSD), implanted by surgeons in human eyes to reduce the IntraOcular Pressure towards physiological values, by draining the AH from the Anterior Chamber to the Suprachoroidal Space, to cure eyes with glaucoma. Design/methodology/approach The generalized porous medium model is solved to simulate the AH flow through the two ocular drainage devices and the surrounding porous tissues of the eye. Findings In the GMS, probable stagnation regions have been found, due to the very small AH velocity values inside the device and to the surrounding tissues, creating possible blockage and malfunction of the device. The simple microtubular geometry of the novel SSD allows to have a regular AH flow and to choose shunts with different diameters and/or with the presence of radial holes, based on patient needs, with consequent reduction of post-operative complications. Research limitations/implications The present model will be further developed taking into account the insertion of the present drainage devices inside the anterior section of the eye. The present results show the comparative fluid dynamic performance of the two shunts considered, and can be useful for surgeons to choose the adequate shunt, based on the required AH flow rate for a specific patient. Practical implications The present numerical approach, employing the generalized porous medium model, represents a useful tool to study the fluid dynamics of ocular drainage devices and to design these shunts, to reduce post-operative complications. Originality/value The generalized porous medium model is here applied for the first time to simulate the interaction of ocular drainage devices with the surrounding porous tissues of the eye.

Abstract:

Wireless Sensor Network is a Wi-Fi community consisting of spatially propagated and self-sufficient devices using sensors to detect physical or environmental conditions. During heavy rainfall, the urban drainage system cannot drain the water. A wireless sensor with many interconnected wireless sensor nodes captures real-time data from the network environment and transmits this data to a base station for analysis and operation. With wireless sensor nodes, it is possible to capture and monitor the amount of water in drainages and the difference in water flow between the two points in the drainage system. Nevertheless, the majority localization techniques aims on device based localization, which can find target with festinated devices. It is not suitable for applications such as terrain, drainage flow and flooding. Here device free wireless localization system using artificial neural networks and a cluster based wireless sensor network system to monitor urban drainage is proposed. There are two stages in the system. During the off-line preparation stage, Acceptable Signal Strength (RSS) differential metrics are calculated between the RSS metrics together while the monitor area is empty and calculated by a specialized in the region. Some RSS dissimilarity values are selected in the RSS Difference Matrix. The RSS dissimilarity standards and associated matrix indices are taken as the inputs of the ANN representation in addition to the identified position coordinate are in its outputs. The real-time data collected from the wireless sensor network is used to detect overflow and provide alarms before disturbances arise.

Abstract:

Summary A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was: what is the optimal level of suction on digital chest drainage devices following pulmonary lobectomy? Altogether 367 papers were found using the reported search, of which 4 randomized controlled trials using digital chest drainage devices represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. The new digital drainage systems enhance early mobilization as recommended in the enhanced recovery after surgery programme. There is, however, no consensus on the optimal level of suction to apply after pulmonary lobectomy. This is especially the case for digital drainage devices. Surgeon preference will likely continue to guide practice, until the evidence gives clear-cut recommendations. According to the current data, a low suction reduces total fluid drainage and perhaps air leak duration compared to higher suction levels in both video-assisted thoracoscopic surgery and open pulmonary lobectomies using digital drainage devices, although the evidence is not overwhelming.

Abstract:

Artificial drainage devices (ADD) create an alternative pathway for aqueous drainage from the anterior chamber of an eye through a tube to the subconjunctival bleb connected to an equatorial plate under the conjunctiva. The ADDs, both valved and non-valved, are available for end stage or refractory glaucoma. Currently, some of these devices, particularly the Express shunt, are recommended for the primary treatment of glaucoma. In this article, we highlight various ADDs, their indications and contraindications, surgical techniques and associated complications.DOI: http://dx.doi.org/10.3126/nepjoph.v4i2.6547 Nepal J Ophthalmol 2012; 4 (2): 295-302

Abstract:

Glaucoma drainage devices are being increasingly used in the treatment of advanced glaucoma refractory to medical therapy or in cases that have failed trabeculectomy with antimetabolite. The Ahmed Versus Baerveldt (AVB) Study is an international, multicenter, randomized clinical trial comparing the two most frequently used devices. Five-year results have been recently published providing high quality evidence to guide a surgeon’s decision on which device to use.

Abstract:

Background: anti-inflammatory and antiproliferative agents are among tools to prevent postoperative scarring. Prolonged use of immunosuppressants characterized by a selective mechanism of action immediately at the surgical site. Aim: to assess the safety and efficacy of bio-resorptive drainage devices enriched with cyclosporine or everolimus in vivo. Patients and Methods: the study was conducted on 52 rabbit eyes. Before to the study, ocular surface disease provoked by the long-term use of preservative-containing IOP-lowering medications was simulated. The next step was the penetrating surgical procedure. The surgery involved implanting bio-resorptive drainage devices of polylactide enriched with cyclosporine or everolimus or control devices (neither cyclosporine nor everolimus). Postoperatively, all rabbits underwent regular ophthalmic exams and IOP measurements. Follow-up was 6 months. After 7 days, 1 month, and 6 months, the animals were slaughtered for the histology of surgical site. Results: better characteristics of filtering blebs and lower IOP values were seen among the animals who underwent surgical procedures with immunosuppressants compared to the control group even in the early post-op period. After 1 month, control filtering blebs stopped functioning and were characterized by the IBAGS H0 (height) and E0 (extent) in most animals. Meanwhile, in cyclosporine and everolimus groups, filtering blebs were characterized by the IBAGS Н1-Н2 and Е1-Е3 till the end of follow-up. After 6 months, mean IOP was 17.3±0.5 mm Hg in the control group and 13.0±0.4 mm Hg and 11.8±0.6 mm Hg in cyclosporine group and everolimus group, respectively. No significant differences between the groups were reported in terms of complications. Histology matched clinical data and illustrated the mechanism of increased outflow facility after the implantation of drainage devices enriched with immunosuppressants. Conclusion: in vivo experiment has demonstrated higher efficacy and similar safety of IOP-lowering surgery after the implantation of drainage devices enriched with selective immunosuppressants.

Abstract:

This article develops techniques and technologies for improving the reclamation of lands. It is based on the parameters of the working bodies of the chisel softener for softening the birch and gypsum layer and the parameters of the device that creates hole drainage before the autumn saline wash in saline soils and their application technologies. Due to the use of devices, porous drainage is created compared to the traditional method, and the duration of saline washing is reduced by 15 days when plowing and saline washing. The annual economic efficiency of the chisel softener is 11645758.8 soums. The annual economic efficiency due to the use of the unit for the creation of perforated drainage amounted to 12678675.5 soums.
