Tourniquets Tourniquets can be used to limit blood loss when excising wounds on the extremi- ties buy arava 10mg free shipping. It is very useful if the tourniquet can be sterilized; if the whole limb is burned order arava 10mg amex, the upper portion can be excised before application of the device without contamination of the operative field. When using tourniquets during burn wound excision, areas requiring electrocautery for hemostasis will not bleed until the tourniquet is removed, thus obviating the usefulness of the tourniquet. One way to avoid this bleeding is to deflate the tourniquet briefly while the extremity is wrapped with a moist gauze and elastic bandages. When the tourniquet is rein- flated, the outer elastic dressings can be removed and significant bleeding areas will be marked by blood staining. This limits blood loss, identifies bleeding vessels in need of hemostasis, and provides a measure of the adequacy of excision by allowing inspection of the wound. My personal practice is to avoid the use of tourniquets except in reconstructive operations. I rely instead on meticulous attention to hemostasis in a wound bed after a timely excision before moving to another anatomical area requiring excision. Standard 10 and 15 surgi- cal blades are used for sharp excision, incisions into fascial planes, and other proce- dures. Specialized knives used for tangential excision include the Goulian knife (Weck blade), and the Watson modification of the Braithwaite knife (Picture 2). The Goulian knife is a blade inserted into a handle, over which a guard is placed. The guard can be chosen to regulate the depth of the excision, which ranges from 4 to 16|1000 inch.

Occurrence Bone tumors Around 5% of all bone tumors in children and adolescents are located in the pelvic area (adults: 10%; ⊡ Table 3. After the distal femur and proximal tibia, this region is the third most commonly affected site ( Chapter 4.

In animals discount 10 mg arava free shipping, we have no direct access to information of pain ex- perience except as reflected in behavior buy arava 10 mg cheap. Could genotype or social convention (including the presence of specific others) change outward pain behavior without actually affecting the “raw feel” of the pain? In humans, the answer is clearly yes, although intuitively one imagines that rodents are less bound by social context (innate or learned), and that pain behavior should therefore more faithfully reflect actual pain sensation. Black, and White, and Asian groups within a single society such as the United States may have enormous differences in child-rearing practices, modeling, and behavioral reinforcement, in addition to whatever genetic factors might distinguish them. One cannot legitimately lump together individuals from China, Japan, Thailand, the Philippines, Singapore, Korea, Indonesia, and so on and pre- tend that they share a single cultural identity that can be labeled “Asian. This is not to say that there are no differences between racial or ethnic groups. Rather, it is to encourage extreme caution in statements based on 174 ROLLMAN small numbers in a single community. African Americans living in a major metropolitan area or a university town are not representative of all African Americans and are certainly not representative of all Blacks. We cannot have it both ways with regard to White participants: to proclaim the sup- posed differences between Irish, Italians, Poles, and Scandinavians, and then to randomly lump a cluster of them together as “Whites” or “Cauca- sians” when we need a group to contrast with Blacks or Asians. It is misleading and potentially detrimental to generalize to all members of one group based on a handful of subjects, often obtained nonrandomly, and who differ from other members of their group in myriad respects.

To the extent that such research shows that there are ethnocultural dif- ferences in pain or the effects of analgesics or the degree of negative affect or the effects of psychosocial interventions, we have a responsibility to identify the evidence and take appropriate action to modify clinical prac- tice guidelines. At the moment, it seems we are best able to say that all pa- tients should be carefully evaluated and treated with respect. Irrespective of their ethnocultural status, their pain reports must be accepted and all ef- forts must be undertaken to reduce their pain and distress.

A trans- verse fracture pattern presents more frequently than a spiral fracture but the latter is more suggestive of abuse as it results from a twisting force (Figs 9 buy arava 10mg line. The most commonly injured long bones are the humerus discount arava 20mg on line, femur and tibia; however, care must be taken not to confuse the fine spiral ‘toddler’ fracture (Chapter 7) with a physical abuse injury. Periosteal elevation The periosteum is the outer sheath of bone and it consists of an inner osteogenic layer and an outer fibrous layer. Strong fibres bind the periosteum firmly to the epiphysis but these attachments are weaker along the disphyseal portion of the long bone and therefore periosteal elevation can occur following subperiosteal Non-accidental injury 199 Fig. Periosteal elevation, although commonly seen on radiographs of physically abused children, is a non-specific condition and care should be taken when examining infants. It is thought that as a response to rapid growth, up to 40% of infants under 4 months of age will show radiographic evidence of periosteal reac- tion5 but unlike a traumatic periosteal response, the appearances are symmetri- cal and do not extend to the metaphysis. Periosteal elevation is a clinically occult injury and healing is through gradual resorption and consolidation of new bone. Repeated trauma may result in multiple layers of periosteum and this may appear extensive. Clavicle fractures The clavicle is one of the most commonly fractured bones in childhood but injuries as a result of abuse are seen in only 2–6% of patients. Accidental fractures tend to be located in the middle third of the clavicle (see Chapter 7) whereas fractures of the lateral end are uncommon accidental injuries and should raise suspicion of abuse (Fig. Rib fractures Accidental rib fractures, particularly those resulting from a compression injury of the thorax, are extremely uncommon in young children and therefore their presence is highly suspicious of abuse (Fig. Rib fractures due to NAI are often multiple (commonly 6th–11th ribs7), bilateral and posterior8. They are thought to be present in up to 25% of cases although the majority are clinically occult5. Rib fractures may be difficult to diagnose radiographically when acute and therefore, if suspected, a repeat x-ray 7–12 days later (when fracture heal- ing by callus formation can be identified) may be indicated. Vertebral fractures Vertebral fractures due to NAI are rare but, should they occur, are usually located in the region of the thoracolumbar spine (Fig.
