If you have been unable to freely aspirate air or fluid from the pleural space, do not proceed further at this site and seek advice from a senior colleague. Seldinger technique 9 Advance the introducer needle mounted on a 10 mL syringe into the pleural space (again, passing just superiorly to the lower rib of the intercostal space) and confirm free aspiration of air or effusion. A small incision (5 mm) may be needed initially to help with passing the dilator through the skin and subcutaneous tissue. Always keep hold of the distal end of the guidewire, and do not insert the dilator any further into the chest than is necessary to breach the parietal pleural surface. In an adult of normal size, around 15 cm of drain will usually lie within the chest. The depth to which a chest tube is inserted is determined by the need to ensure the side holes on the tube are well within the chest, otherwise subcutaneous emphysema will result. Remove the guidewire and any stiffening device/dilator used to help introduce the chest tube, leaving the tube itself in place. Large-bore drains (>14 French) inserted with a blunt dissection technique are used less frequently than before, but are still seen in emergency trauma or thoracic surgical cases. These should be left loose so the tube can pass, and will be tied when the tube is removed. Place a separate 1/0 non-absorbable suture through the skin and subcutaneous tissues above the incision, which will be used to anchor the chest tube later (Figure 122. Note that the forceps should always be removed in an open position during the process of blunt dissection to prevent accidental avulsion of any structures, for example blood vessels. Once a track has been created, this should be explored with a finger to ensure there are no underlying organs that might be damaged during subsequent chest tube insertion. The tube should ideally be directed apically for a pneumothorax and posterobasally for an effusion. In an adult of normal size, around 15 cm of the chest tube will usually lie within the chest. The tube must be inserted far enough so that the side holes are well within the chest, otherwise subcutaneous emphysema will result. Final points 14 Remove the drapes and ensure the patient is able to sit up comfortably. Check that the chest tube is well anchored, all connections are secure and the dressings are satisfactory. Opioid analgesia may also be necessary on a regular or as required basis; this should be reviewed daily to ensure the patient is pain free. Controlling the rate and volume of fluid drainage in this way is necessary to reduce the risk of causing re-expansion pulmonary oedema.

Most of the signal is related to absent meniscal tissue that now extends into the inferior recess chronic gastritis diet mayo clinic purchase lansoprazole master card. Horizontal tears are rarely well seen on axial images because the plane of the tear parallels the imaging plane diet untuk gastritis akut lansoprazole 30mg otc. Radial tears begin at the free edge of the meniscus and propagate a variable distance toward the peripheral (capsular) margin gastritis que es discount lansoprazole 15mg with amex. Thin- section (3 mm) axial fluid-sensitive images often demonstrate radial tears well. This finding may be subtle with small radial tears, but it is fairly specific when identified. This finding may be seen postoperatively or with degenerative meniscal subluxation. They usually arise in the posterior horn and may propagate into the body and anterior horn. When vertical tears extend along a larger portion of the meniscus, they may displace and become bucket-handle tears. The central fragment of the meniscus is large enough that it could be mistaken for the entire posterior horn and interpreted as intact. The small peripheral meniscal fragment distinguishes this tear from a meniscocapsular separation. This tear is unusual in that it is located in the redwhite zone instead of the more typical location of the peripheral (red) zone. Tears are more likely to heal spontaneously (or after repair) in the vascular red zone. It is important to recognize these tears, as they may become displaced if not treated. Longitudinal tears, and all tears, are far less common in the anterior horn than in the posterior horn. Peripheral vertical longitudinal tears are particularly common in association with tears of the anterior cruciate ligament and should be specifically sought in such cases. A 2nd cleft of fluid is seen between the meniscus and the posterior joint capsule, indicating partial meniscocapsular tear. The tear is approaching the popliteal hiatus; the popliteus tendon can be seen entering the joint capsule more posteriorly. The normal junction of the anterior horn and the transverse intermeniscal ligament assumes a more oblique course, angled anteroinferior to posterosuperior. This is the "tip of the iceberg" of a more complex tear, and the remnant posterior horn may have a variety of appearances in this setting. The bucket-handle fragment remains attached at the posterior horn as well as the nondisplaced peripheral portion of the meniscus anteriorly. The displaced bucket-handle meniscal fragment is located within the intercondylar notch.
Because the literature regarding knee imaging is bountiful gastritis olive oil discount lansoprazole express, there is at once both an opportunity and an obligation for the radiologist to stay current with the latest techniques and reading strategies chronic gastritis years generic lansoprazole 30mg with visa, lest s/he fall behind gastritis diet цитаты order generic lansoprazole online. This section explores the full range of knee trauma pathology seen in a modern practice, using the latest published data available. Pathologic Considerations Injury to the knee is a common occurrence across the age spectrum, and thus results in a high frequency of imaging studies in a typical practice. Injury to the knee is often related to sports activity and, as such, may be either acute or the result of chronic repetitive microtrauma. In either case, it is often the ligaments, tendons, and cartilage of the knee that bear the brunt of such injuries. In particular, tears of the menisci of the knee and focal or diffuse articular cartilage defects account for significant disability in modern Western society, and accurate imaging evaluation of these injuries may serve to target appropriate therapy, and in some cases, may obviate surgical intervention. An understanding of the typical injury patterns encountered in the knee will aid the radiologist, both in recognizing common injuries and in anticipating more subtle but clinically relevant findings based on their association with these injury patterns. Terminology and Conventions Degenerative changes in a tendon are referred to as tendinopathy, and not as tendinitis or tendinosis, in an effort to stay true to the appropriate etymologic meanings of these terms. The term spontaneous osteonecrosis of the knee is not used, but is instead covered under the section on osteochondral injury, as this imaging finding is thought by most authors to be due to shear trauma &/or insufficiency fractures. Anatomic Considerations the femorotibial (knee) joint is a simple hinge, with very little rotational motion occurring at the articulation in normal physiologic motion. A few degrees of external tibial rotation occur in terminal extension, serving to lock the knee and reduce the need of constant muscular action to help hold the knee in this position during standing (this is sometimes referred to as the screw-home mechanism). The popliteus muscle serves to rotate the femur externally during initiation of flexion in order to unlock the knee. The patella is a large sesamoid bone in the quadriceps tendon complex and articulates with the trochlear groove of the femur in order to increase fulcrum length of the quadriceps units and reduce friction between the tendons and the femur. The 2 ligaments also resist rotational knee motion and complement each other in that function. The medial collateral ligament resists valgus forces, and the lateral collateral ligament complex resists varus forces. The posterolateral corner ligament complex is a series of mostly capsular thickenings that serve to stabilize this important part of the joint. The menisci are fibrocartilage wedges conforming to the shapes of the tibial articular condyles; they serve to cushion the impact of the femur on the tibia during weight-bearing. The medial meniscus is larger and has a larger radius of curvature than its lateral counterpart. The medial meniscus is also more firmly attached to the bones than is the lateral meniscus, allowing more lateral meniscal motion during flexion and extension. The menisci derive their blood supply from a vascular pedicle that enters at the capsular margin of the meniscus. Vascularity within the meniscus becomes progressively more sparse toward the central free edge and diminishes in general in older patients. Because of its superficial location, the common peroneal nerve is the only commonly injured nerve in the knee region. It 636 Imaging Considerations Radiographic evaluation of the knee usually includes 3 standard views, but in the setting of trauma may be limited to anteroposterior and lateral projections. A cross-table lateral view is useful in the setting of acute trauma, as a large lipohemarthrosis may be visible as fat-fluid levels in the suprapatellar joint recess and serve as an indicator of intraarticular fracture. The axial patellofemoral (sunrise) view is useful for evaluating patellofemoral arthritis and alignment, though less valuable in the setting of acute trauma (except patella fractures). Because they may be anatomically complex, these fractures Knee Overview Knee are difficult to fully evaluate with routine radiography.
