What is it?
An external ventricular drain (EVD) is a medical device that is used to drain excess cerebrospinal fluid (CSF) from around the brain. It is commonly placed during neurosurgery to relieve elevated intracranial pressure. An EVD consists of a catheter that is inserted through a small hole in the skull and placed into one of the ventricles inside the brain. The other end of the catheter leads to a drainage system outside of the body. This allows for continuous drainage and monitoring of CSF to ensure normal pressure levels are maintained. EVDs are most often used on a temporary basis for conditions that cause increased intracranial pressure such as traumatic brain injury, hemorrhage, tumors, and hydrocephalus. Once the underlying condition has improved and pressure has stabilized, the drain is typically removed. External Ventricular Drains some patients require long-term drainage with an EVD if their hydrocephalus cannot be treated another way. Proper placement and care of an EVD is crucial for effectively managing increased intracranial pressure and optimizing patient outcomes. Indications and Benefits of EVD Placement As mentioned, EVDs are commonly placed to treat elevated intracranial pressure from various neurological conditions and injuries. Some specific indications for EVD placement include: - Traumatic brain injury - Head injuries that cause bleeding, swelling, and increased pressure inside the skull. Draining excess CSF helps reduce pressure and decrease risk of further injury. - Intracerebral hemorrhage - Bleeding within the brain tissue such as from a ruptured aneurysm or arteriovenous malformation. Drainage controls swelling to prevent additional damage. - Subarachnoid hemorrhage - Bleeding occurring between the brain and the tissues covering it, often from an aneurysm. EVDs are used pre- and post-operatively to manage pressure levels. - Hydrocephalus - A neurological condition where excess CSF builds up in the ventricles, putting pressure on the brain. This is either treated short-term with an EVD until a permanent shunt can be placed or long-term with a ventriculoperitoneal shunt. - Brain tumors - Both cancerous and non-cancerous growths can cause swelling and increased pressure inside the skull. An EVD provides decompression prior to surgery or radiation/chemotherapy treatments. The main benefit of EVD placement is that it allows for continuous and precise monitoring and drainage of CSF to maintain normal intracranial pressure levels. This protects the brain from further injury and optimizes recovery from the underlying problem causing increased pressure. Proper Placement and Ongoing Care Accurate external ventricular drains placement involves careful image-guided insertion of the catheter into one of the ventricles deep within the brain. An entry point is made just above the hairline using sterile technique. Advanced monitoring modalities like ultrasound or computer tomography ensure the distal tip reaches the targeted ventricle location. Once placed, the external portion of the catheter is connected to a closed drainage and monitoring system. Adjustable clamping of the drain tube regulates outflow of CSF and maintains desired pressure. The amount and characteristics of drained fluid are logged. Any changes could indicate complications warranting medical review. To prevent infection, utmost care is given to keep the catheter exit site clean and dressed. Strict hand hygiene is followed during dressing changes which are typically performed every 1-3 days depending on the condition of the insertion tract. Antibiotic ointments are often applied. The whole drainage assembly is also changed regularly depending on the healthcare facility's protocols to reduce infection risks. Additionally, bedside monitoring devices linked to the EVD tubing allow for continuous measurement of intracranial pressure levels which are also logged. Abnormal pressures may prompt medical intervention like adjusting the CSF drainage rate to bring pressure back within a safe target range. Overall management involves a team approach between neurosurgeons, nurses and other specialists. Complications and Their Management While external ventricular drains placement provides lifesaving drainage, there are also certain risks involved: - Infection is a leading complication occurring in 5-25% of cases. Strict sterility precautions must be followed during insertion, care and all contact with the drainage system. Antimicrobial therapies manage suspected or confirmed infections. - Hemorrhage can result from damage to brain blood vessels during catheter insertion, occurring in 1-10% of EVD placements. Bleeding is carefully controlled in the operating room and patients are closely monitored post-procedure. - Malposition happens when the catheter tip is misplaced outside the ventricles rather than inside, seen in 5-15% of procedures. Adjustment or replacement of the drain may be needed under imaging guidance. - Blockage can occur from fibrin or blood clots forming on or within the catheter, requiring catheter irrigation or replacement in 10-35% of cases. - There is a small risk of over-drainage causing issues like edema or subdural hematomas in 1-2% of cases. Pressure monitor-guided drainage oversight aims to prevent this. With experienced placement, diligent ongoing care, and prompt response to any warning signs, risks are minimized and EVDs effectively accomplish their purpose of controlling intracranial pressure in eligible patients. Overall, external ventricular drain remains a vital neurocritical care intervention globally. Get more insights on This Topic- External Ventricular Drains

Electronic warfare (EW) has evolved significantly since its early beginnings in World War II. During the war, early radars were used to detect enemy aircraft and guide defensive fire, while allied forces also started employing basic forms of radar jamming to degrade enemy systems. In subsequent conflicts like the Cold War and Vietnam War, EW grew in sophistication as new radar, communication and electronic sensor technologies emerged on both military platforms and ground systems. Countries invested heavily in developing specialized EW aircraft, vehicles and other assets that could identify, locate, disrupt or deceive the enemy’s use of the electromagnetic spectrum.
By the 1990s, the proliferation of microelectronics and digital signal processing led to another leap forward. Electronic Warfare Advanced EW suites became standard on modern fighter jets and warfare ships, providing comprehensive electronic protection, signals intelligence, and electromagnetic attack capabilities. Space-based intelligence assets also augmented traditional ground and airborne EW platforms. This paradigm shift transformed EW into a core warfare domain on par with air, land, sea and space. Modern Electronic Warfare Assets and Tactics Today’s advanced militaries employ a diverse array of specialized EW assets ranging from manned and unmanned aircraft to ground and maritime vehicles. These systems deploy an extensive toolset for conducting electronic support, protection and attack missions across multiple frequency bands. For example, specially configured E-3 Sentry, EA-18G Growler and other aircraft conduct deep sensing of enemy radar, communication signals and cyber emissions over vast areas. They can then program this electronic “order of battle” data into weapons like missiles, bombs and frequency jammers to autonomously attack specific threats. Dedicated EW tactical vehicles like the AN/MLQ-40 also provide real-time targeting, tracking and jamming of radio/radar signals on the move right alongside ground troops. Moreover, distributed EW networks, consisting of many interconnected air, sea, space and ground nodes, help coordinate electromagnetic deception across entire joint battlespaces. Shipboard and land-based EW suites similarly work in concert to counter enemy targeting efforts over broad maritime and coastal regions. Such networked approaches allow EW assets to rapidly reconfigure jamming and cyber payloads based on evolving threats, maximizing disruption while minimizing own exposure. Emerging Technologies Transforming EW Paradigms New technological trends continue augmenting EW capabilities for both offense and defense. Advancements in materials science enable next-gen conformal antennas, metamaterials and frequency agile payloads providing unprecedented electromagnetic control. Wideband digital receivers and programmable jamming waveforms afford immense multi-spectral sensing and deception. Artificial intelligence/machine learning algorithms also optimize recognition of complex signals across vast bandwidths in real-time. Combined with automated target recognition, they equip EW systems to precisely characterize, prioritize and quickly attack the most critical emitters. Hypersonic cruise missiles and hypervelocity projectiles further extend the reach of kinetic EW effects beyond traditional line-of-sight limitations. However, enhancing own assets also widens the attack surface for adversaries’ growing cyber and directed-energy arsenals. Balancing operational security with electromagnetic superiority requires judicious use of low-observability coatings, dispersed sensing architecture, and dynamic defensive techniques. Overall, the transformation of underlying technologies ensures EW will remain a key facet of modern militaries’ multi-domain maneuverability well into future battlefields. Regulation of Electronic Warfare under International Law While electronic warfare has become an indispensable military capability, nations conducting EW operations must still operate within the bounds of international humanitarian law. Certain EW tactics or payloads that cause indiscriminate or disproportionate harm to civilian infrastructure can potentially violate laws of armed conflict. Similarly, deliberate attacks on protected civilian/neutral communications may breach the principle of distinction between military and non-military targets. Most EW effects are generally considered lawful if narrowly tailored to degrade specific adversarial military system functions without collateral damage. However, emerging capabilities using lasers, microwaves or cyber induce novel compliance questions. Neutral parties may also protest opaque or uncontrolled EW spillover risks endangering their commercial activities or territorial integrity. Overall, prudent interpretation and adherence to established international law principles help address such challenges and maintain legitimacy of EW activities on the global stage. Looking ahead, evolving technology and hybrid warfare trends point to an increasing need for updated EW norms and governance structures.
