i'm gonna need one of those fucking anticoagulant mushrooms bc i think a blood vessel is occluding in my brain.

[ask-a-vetblr]

I have trouble finding the pulse on patients (we work with dogs and cats). I know where it is located but it takes me 2 years to finally feel it. Do you have any tips?

vet-and-wild here.

I used to hate this answer but now I've realized how true it is: practice. Honestly, just practice with every animal you can and it'll start to become second nature. But there are some things that may either help or hurt (assuming we're talking about femoral pulses here):

-Good luck finding it when they're sitting/laying. Sometimes I can get it on a laying animal but it's always harder than if they're standing.

-Don't press to hard, you might be accidentally occluding the vessel.

-Overweight animals or little stubby legs can be tricky.

The best animals to practice on are large, fit, short haired dogs. If you want an easy target, that is. It's generally really easy to find on those kind of dogs and it can help you get comfortable with anatomy until it becomes easier to apply to smaller/sicker things.

oh boy howdy does KSP function on some troll physics logic. no, like literally. docking ports have a slight magnetism to them to make alignment easier, but if you put two docking ports on the same vessel and point them at each other, it'll pull your vessel along with no external force.

it's fucking goofy

another fun bit is how KSP only loads structural physics (calculating joint strengths and stuff) within a radius of 2300m of the active vessel, measured from the root node, but it calculates collisions at much further distances. this means that you can build huge megastructures that should collapse under their own weight, but make them infinitely strong by just offsetting the root node away from the rest of the "vessel" by 2300m

my personal favorite category of exploits is drag occlusion - by using fairings, engine plates, and sneaky offsetting you can make craft that have literally zero air drag, and do goofy shit like orbit at an altitude of 500m with a craft that looks like a brick.

the only reason this works is because doing actual fluid dynamical simulations is pretty infeasible, so KSP cheats by calculating drag individually for each part, but considering some parts to be "occluded" so you don't get additional drag from stuff that's streamlined with the rest of the rocket or hidden inside cargo bays. this works reasonably well until you become aware of it and start optimizing for it.

tldr Kerbal is a clownshit game held together by popsicle sticks and chewing gum and you should absolutely play it

Kerbal Space Program was once afflicted by a bug the fans dubbed the "Deep Space Kraken", whereby if you travelled far enough from the origin of the game's coordinate system, floating point rounding errors would cause your spacecraft's components to become misaligned and/or clip into each other, resulting in the craft falling apart or exploding for no obvious reason.

The bug was later fixed by defining the active spacecraft itself as the origin of the game's coordinate system. In effect, the spacecraft no longer moves; instead, the spacecraft remains stationary and the entire universe moves around it. Owing to how relativity works, to the player this is indistinguishable from the spacecraft moving about within a fixed coordinate system, and it ensures that the body of the craft and its components will always be modelled with maximal precision.

While elegant, this solution introduced a new problem: it was now possible, by doing certain stupid tricks with relativistic velocities, to introduce floating point rounding errors to everything except the active spacecraft. In extreme cases, this could result in the destruction of the entire observable universe.

Some might call this one of those situations where the solution proves to be worse than the problem. I call it a perfect expression of what Kerbal Space Program is truly about.

Crile Hemostatic Clamp: A Crucial Instrument in Surgery

The Crile hemostatic clamp is a widely used surgical instrument designed for clamping blood vessels and controlling bleeding during medical procedures. Named after Dr. George Crile, this instrument plays a vital role in maintaining a clear and blood-free surgical field, allowing surgeons to work with precision and efficiency. Crile hemostatic clamp is a fundamental tool in general surgery, emergency procedures, and specialized fields such as cardiovascular and orthopedic surgery.

Design and Features of the Crile Hemostatic Clamp

The Crile hemostatic clamp is medium-sized, typically measuring 5.5 to 6.5 inches (14-16 cm) in length. It has serrated jaws that extend along the entire length of the tip, differentiating it from other hemostats like the Kelly forceps, which have serrations only on the distal half. This full serration ensures a secure grip on blood vessels and tissues, preventing slippage during procedures.

The instrument comes in two variations: straight and curved. The straight Crile clamp is ideal for superficial procedures, where a direct grip is needed, while the curved version provides better access to deep or confined surgical sites, making it useful for clamping vessels without obstructing the view. It is made of high-quality stainless steel, ensuring durability, corrosion resistance, and compatibility with autoclave sterilization.

A key feature of the Crile hemostatic clamp is its ratcheted locking mechanism, which allows the surgeon to lock the clamp in place at different levels of tightness. This enables a hands-free grip, ensuring that vessels remain clamped throughout the procedure without continuous manual pressure.

Primary Use in Hemostasis

The main function of the Crile hemostatic clamp is controlling bleeding by clamping small to medium-sized blood vessels. During surgery, uncontrolled bleeding can obscure the surgical site and increase complications, making hemostatic instruments like the Crile clamp indispensable.

By applying controlled pressure to a vessel, the Crile clamp halts blood flow temporarily, giving the surgeon time to ligate (tie off) or cauterize (seal) the vessel. This helps prevent excessive blood loss and maintains a clear surgical field. The secure serrated grip ensures that vessels remain clamped without being crushed, preserving their integrity for later repair if necessary.

Use in Tissue Handling and Dissection

Apart from controlling bleeding, the Crile clamp is also used for grasping and holding tissues during dissection. In certain procedures, tissues need to be retracted or manipulated to improve visibility and access. The delicate yet firm grip of the Crile clamp makes it useful for this purpose, especially in abdominal, thoracic, and orthopedic surgeries.

Additionally, the Crile clamp can be used in blunt dissection, where the closed clamp is inserted into soft tissue and gently opened to separate layers. This technique is commonly employed in vascular and nerve surgery, where precision is essential.

Applications in Various Medical Fields

The Crile hemostatic clamp is a versatile instrument used in multiple surgical disciplines. In general surgery, it is a go-to tool for clamping bleeding vessels, handling tissues, and assisting in suturing. In cardiovascular procedures, it plays a crucial role in temporarily occluding small arteries and veins, ensuring controlled blood flow.

In gynecological and obstetric surgeries, such as C-sections and hysterectomies, the Crile clamp helps manage bleeding from the uterus and surrounding tissues. It is also frequently used in dental and oral surgeries, where precise control over small vessels is necessary. Veterinary surgeons also rely on Crile clamps for spay, neuter, and other small-animal procedures.

Difference Between Crile and Other Hemostatic Forceps

While the Crile clamp is similar to other hemostatic forceps, it has distinct differences. Compared to Kelly forceps, the full-length serrations of the Crile clamp provide a firmer grip on blood vessels, making it more reliable in certain procedures. Compared to Halsted mosquito forceps, which are smaller and used for fine, delicate vessels, the Crile clamp is better suited for medium-sized vessels and tissues.

Advantages of the Crile Hemostatic Clamp

One of the biggest advantages of the Crile hemostatic clamp is its effectiveness in achieving hemostasis quickly and efficiently. The ratcheted locking system allows for a secure, hands-free grip, reducing the need for constant manual pressure. Its versatility in different surgical specialties makes it a valuable instrument in both routine and emergency procedures.

Made from high-quality stainless steel, the Crile clamp is reusable, easy to sterilize, and highly durable. Additionally, disposable versions are available for use in infection-prone environments where single-use instruments are preferred.

Conclusion​​​​​​​

The Crile hemostatic clamp is a fundamental surgical tool used for controlling bleeding, holding tissues, and assisting in dissection. Its full-length serrated jaws, ratcheted locking mechanism, and durable stainless steel construction make it a versatile and reliable instrument in general surgery, cardiovascular procedures, obstetrics, dentistry, and veterinary medicine. Whether in routine operations or emergency settings, the Crile clamp remains an essential instrument for surgeons worldwide.

¶ … Vascular Disease Randy Jackson Geriatric Nursing The disease known as Peripheral Vascular Disease (PVD), according to the American Heart Association (AHA, 2004), involves the blood vessels "outside the heart and brain." This disease refers to a narrowing of those vessels that carry blood to one's leg and arm muscles. In particular, the AHA states that there are two forms of PVD: one is "Functional Peripheral Vascular Disease," and the other is "Organic Peripheral Vascular Disease." The first, Functional PVD, does not allude to actual defects in the structure of the blood vessel, but rather refers to "short-term effects" caused by cold temperatures, stress caused by emotions, smoking, or handling machinery that vibrates powerfully. The second form of PVD - "Organic" - is actually caused by "structural changes" in blood vessels. These changes may be inflammation, tissue damage, or the buildup of fatty substances in the arteries, called "atherosclerosis" - which restricts good blood flow to the body's limbs. Atherosclerosis is particularly insidious in its attack on one's health because people "are unaware of the disease process" (Barker, et al., 2003) until "nearly 75% of the artery is occluded." And unlike "Functional" PVD, these above-mentioned changes in vessels are not temporary. What are the signs and symptoms of PVD? According to the Townsend Letter for Doctors and Patients (Barker, et al., 2003), there are "many predisposing factors," including: High Blood Pressure; Diabetes; a family history of members with diabetes or other cardiovascular issues such as stroke, myocardial infarction and hypertension; "Aching or cramping in the legs while exercising that resolves upon rest"; pain in the feet or toes at night; wounds that heal slowly; a history of smoking cigarettes; being overweight; the regular consumption of fried and heavily-fatty foods; and a lack of regular exercise. Some two million people currently suffer from PVD, according to Meletis, and PVD is the "leading cause of amputations" in the U.S. One of the debilitation effects of PVD is stasis ulcers - those are ulcerations that appear on legs as a result of reduced blood flow through legs; the age group most closely associated with stasis ulcers is the elderly. One way to lesson the severity of stasis ulcers is through increased physical activity, which helps increase circulation. Another important element in terms of lessening the effects of hardening of the arteries in the legs, according to the Society of Interventional Radiology (PR Newswire, 2003), is to quit smoking. "PVD is caused by atherosclerosis, which is often due to smoking," the article states. Those blocked leg arteries "can result of stroke or heart attack." Two hopeful and positive treatments for PVD are now being used for PVD patients. The Food and Drug Administration approved a new procedure called "CryoPlasty" in late 2003. CryoPlasty (Knight-Ridder, 2004) is quite similar to "balloon angioplasty," with one major difference: in CryoPlasty, the balloon "is filled with pressurized nitrous oxide instead of saline solution." So, the gas freezes the walls of the artery for a few seconds, which, the article reports, reduces the chance of blockage "due to damage inflicted by the balloon." Doctors who have used CryoPlasty say it is a 45-minute procedure, and patients remain awake. The second hopeful and potentially helpful remedy for PVD is a drug called "Liprostin," which is being tested on PVD patients in Mexico and Russia this year. Manufactured by Endovasc, Liprostin is a "potent vasodilator and platelet inhibitor" (Health & Medicine Week, 2003), in addition to being an "anti-inflammatory" agent. Basically, Liprostin has proven to be effective in increasing blood circulation, and reducing leg pain by "increasing oxygen and nutrients in blood-starved muscles." If this drug becomes widely available, it could be a life-saver for many senior citizens, for this age group, know to struggle with blood circulation issues, is by far the most susceptible to PVD.

Shunting Clamps: Precision Instruments for Controlled Blood Flow in Surgery

Shunting clamps are crucial surgical instruments used to temporarily occlude or redirect blood flow during medical procedures. Shunting clamps specialized clamps are designed to provide precise control over circulation, ensuring that surgeons can operate on delicate vascular structures without excessive bleeding. Their role is particularly vital in cardiovascular, neurosurgical, and transplant surgeries, where maintaining proper blood flow can be the difference between success and complications.

The Structure and Mechanism of Shunting Clamps

Shunting clamps are designed with precision and functionality in mind. They feature long, slender handles for ease of control and finely crafted jaws that apply just the right amount of pressure to blood vessels. Depending on the surgical need, these clamps may have smooth or serrated jaws, with some featuring a curved or angled tip for better access to deep or hard-to-reach areas. The locking mechanism ensures that the clamp remains securely in place during the procedure, providing a stable and controlled occlusion.

One of the defining features of a shunting clamp is its atraumatic design. Unlike regular hemostatic clamps, which may cause significant pressure and potential damage to the vessel walls, shunting clamps are engineered to hold vessels securely while minimizing trauma. This reduces the risk of complications such as vessel rupture, clot formation, or tissue necrosis.

Applications in Cardiovascular Surgery

Shunting clamps play a critical role in cardiovascular procedures, where controlling blood flow is essential to patient safety. During coronary artery bypass grafting (CABG), these clamps help temporarily occlude arteries while surgeons connect the bypass grafts, ensuring that oxygenated blood continues to reach vital organs. Similarly, in carotid endarterectomy—a procedure to remove plaque buildup from the carotid artery—shunting clamps work alongside vascular shunts to keep blood flowing to the brain while the artery is being cleaned.

These clamps are also commonly used in aneurysm repair, where blood flow needs to be temporarily rerouted to prevent rupture. Their ability to provide a secure yet gentle hold on blood vessels makes them indispensable in procedures where even minor damage to vascular structures can have life-threatening consequences.

Importance in Neurosurgery and Transplantation

In neurosurgery, shunting clamps are used to regulate blood flow during delicate operations on the brain and spinal cord. When removing an arteriovenous malformation (AVM) or clipping an aneurysm, these clamps allow surgeons to isolate affected blood vessels while preserving circulation to surrounding tissues. By carefully controlling blood supply, neurosurgeons can prevent excessive bleeding and ischemic damage, improving patient outcomes.

Transplant surgery is another area where shunting clamps prove essential. During organ transplants, surgeons must temporarily halt blood flow to the donor organ while ensuring that the recipient's circulation remains stable. The precision and reliability of shunting clamps help facilitate seamless vascular connections, increasing the chances of a successful transplant.

Conclusion

Shunting clamps are indispensable tools in modern surgery, offering precise and atraumatic control over blood flow in critical procedures. Their use in cardiovascular, neurosurgical, and transplant surgeries highlights their importance in maintaining circulation while minimizing surgical risks. With ongoing advancements in medical technology, these instruments continue to evolve, further enhancing their role in improving patient safety and surgical outcomes.

I went looking for a particular illustration of how these work that I'd seen elsewhere online, but couldn't find a version that was attributed. The illustration style was something I was sure I'd seen somewhere, so I checked and found it — these are from the journal Experimental Musical Instruments, Vol. 14 #1 (September 1998), in an article written and illustrated by artist and musician Brian Ransom:

The top image shows how your basic "whistle" version works; the changing position of the water in the chambers forces air out through the whistle mouth. The second image (seen less often online) is how the more warbling, bird-like sounds are made. The air intake in the first chamber is more occluded, so a vacuum is formed that pulls bubbles back through the connecting channel, interrupting the flow and producing the wavering sound.

According to the article, the vessels have been found from southern Peru to Mexico, and were made as early as 1200 BCE; production stopped pretty abruptly with European contact, so it's likely they served a spiritual/religious purpose as well as an artistic one, and that got stamped out with the conquest.

(I'm seeing some stuff online, mostly in woo-woo pieces about these things' healing properties, about how these were just considered weird water jars by archeologists until 1972, when some white author figured out they whistled; since the article by Ransom doesn't mention him, mentions his own experiences in 1978, and cites a 1951 book, Instrumentes musicales del Peru (Musical Instruments of Peru), I'm leaning towards considering that self-aggrandizement at best.)

(EMI was edited and published by Bart Hopkin, author of Musical Instrument Design, between 1985 and 1999; all 72 issues are up on the Internet Archive. It's primarily about non-electronic instruments, but does have scattered articles on electrical amplification and circuit bending.)

Understanding Slotted Tube vs. Woven Nitinol Stents in VSD Occluders

Ventricular Septal Defect (VSD) occluders are medical devices designed to close holes in the heart's ventricular septum. These occluders often utilize stents made from nitinol, a nickel-titanium alloy known for its superelasticity and shape memory. The two primary designs for these stents are slotted tube and woven configurations.

Slotted Tube Nitinol Stents

Slotted tube stents are manufactured by laser-cutting a solid nitinol tube to create a specific pattern of slots. This design allows the stent to expand and conform to the vessel's shape. However, studies have shown that slotted tube nitinol stents may have higher rates of subacute thrombosis and vascular injury compared to stainless steel stents.

Woven Nitinol Stents

Woven nitinol stents are constructed by interlacing multiple nitinol wires to form a mesh-like structure. This interwoven design provides high flexibility, strength, and resistance to kinking. For instance, the Supera™ Stent's unique interwoven nitinol design offers unparalleled strength and flexibility, making it suitable for dynamic vascular environments.

Comparative Analysis

When comparing slotted tube vs. woven nitinol stents, several factors come into play:

Flexibility: Woven nitinol stents exhibit higher flexibility due to their interlaced wire structure, allowing them to conform better to the vessel's natural movements.

Strength: The interwoven design of woven nitinol stents provides superior radial strength and compression resistance compared to slotted tube designs.

Thrombosis Risk: Slotted tube nitinol stents have been associated with higher rates of subacute thrombosis and vascular injury in certain studies.

Conclusion

In the context of VSD occluders, understanding the differences between slotted tube vs. woven nitinol stents is crucial. Woven nitinol stents offer advantages in flexibility and strength, making them a preferred choice in dynamic vascular environments. However, the selection between slotted tube vs. woven nitinol stents should be based on individual patient needs and specific clinical scenarios.
