Requirements for Debridement
The requirements for debridement were as follows: 1. * * In terms of surgical operation ** - * * Debridement according to sequence and anatomical level **: Debridement should be carried out according to a certain sequence and anatomical level, from shallow to deep, and gradually expand the surgical scope until the debridement is complete. For example, when dealing with different tissues such as skin, deep fascia, muscles, tendons, blood vessels, nerves, and fracture ends, there were corresponding operating specifications. - [Completely remove the deactivated tissue: This is the key goal of debridement.] Different tissues had different criteria for determining the loss of activity. For example, muscles were based on 4C.(color, circulation, contractile force, toughness) to judge the devitalization and debridement. The muscle debridement should be more thorough until there is active oozing blood to prevent infection by anaerobia; the skin should be removed from the parts that have been destroyed and lost vitality, and the uneven edge should be removed by 1 - 2 mm; the severely polluted and lifeless tendon should be removed; if there is pollution in the marrow cavity, a curet can be used to go 1 - 2 cm deep into the marrow cavity to scrape. - * * Reduce damage to healthy tissues as much as possible **: When removing dead tissues, avoid causing unnecessary damage to healthy tissues. - * * Make sure there is no foreign body left **: After cleaning the wound, make sure there is no foreign body or dead tissue left in the wound. 2. * * Requirements for the rinsing phase ** - * * Choice of rinsing fluid **: You can use tap water, isonotic saline, 1:1000 solution, low-concentration iodine-based rinsing fluid, and 3% hydrogen peroxide-based rinsing fluid (for certain special wounds suspected to be infected with anaerobia) to rinse. Among them, the pulse irrigation method (spraying about 700 ml of water at a speed of 800 - 1200 times/min, and the pressure was 196 - 245 kPa) was more effective, but it might bring superficial contamination into the deep part of the wound. The hydraulic debridement system used ultra-high-speed water flow to accurately cut and simultaneously suck back the deactivated tissues, bacteria, contamination, and biofilms of the wound. It was more efficient and would not bring superficial contamination into the deep tissues. - * * Washing method **: When washing, pay attention to the fact that the rinsing liquid should not flow into the wound to prevent further pollution; if the pulse washing method is used, pay attention to its advantages and disadvantages. 3. * * Asterile Operation Requirement **: Debridement must be performed under sterile conditions to prevent infection. 4. * * Post-surgical requirements ** - * * Wound treatment **: If the wound is deep or large, consider suturing or skin transplantation. After the surgery, keep the wound clean and change the dressing regularly to promote healing. - * * Treatment of special circumstances **: For example, placing a drainage tube (when the wound is very deep) to help drain the liquid in the wound.
What are the requirements for debridement?
The requirements for debridement were as follows: 1. ** Time Requirement **: Debridement should be performed as soon as possible after the injury. It is best to perform it within 6 - 8 hours of the injury. Sometimes, it can be extended to 12 - 24 hours. 2. ** Pre-operation Assessment Requirements ** - First of all, he had to judge the entire injury to prevent missed diagnosis. According to the injury mechanism, clinical manifestations, and comprehensive examination, he had to understand the severity of the injury and the general condition of the body. He had to judge whether there were deep injuries in the brain, chest, abdomen, and limbs or if there were other multiple injuries. - If a trauma patient went into shock, they would need to be rescued first before debridement was carried out after the patient's condition stabilized. - Observe whether there is any bone, blood vessel, nerve, tendon, or other trauma in the wound. If necessary, perform corresponding examinations. It is not recommended to use instruments or fingers to explore the wound before debridement. - The anesthesia method was chosen according to the location of the injury and the condition of the wound. 3. ** Operation Requirements ** - Wound cleaning: Wash the wound with sterile physiological salt solution to remove dirt and impurities. If the wound is seriously contaminated, the cleaning should be carried out under anesthesia. Cover the wound with sterile gauze and remove or cut off the hair around the wound (the scope should be large). The skin around the wound should be scrubbed with soap water or washed and dried with an isonotic salt solution. Then, wash the wound repeatedly with sterile physiological salt solution. If necessary, wash it with 3% hydrogen dioxide to completely remove foreign bodies, blood clots, tissues and fragments in the wound. Then, cover the wound with a sterile wound. - Removing the dressing (if any): Carefully remove the dressing from the wound. - Disinfect the wound: Use disinfectant (such as povidone) to disinfect the wound. The disinfection range should be at least 5 cm beyond the edge of the wound. - Removing dead tissue: Use a scalpel or surgical scissors to remove the necrotic skin, muscle, and fatty tissue on the wound. Try to minimize the damage to healthy tissue during the removal. - Clean the wound again: Wash the wound with normal saline again to ensure that it is clean and that there are no foreign objects or dead tissues left in the wound. - If the wound is very deep, a drainage tube may be placed to help drain the fluid from the wound. - Dressing the wound: Cover the wound with a sterile dressing and bandage it. 4. ** Post-surgery requirements **: After surgery, the wound must be kept clean, and the dressing must be changed regularly to promote healing. If the wound is deep or large, it is necessary to consider suturing or skin transplantation. At the same time, debridement needed to be carried out under the guidance of a doctor. If there were any doubts or uncertainties, the doctor should be consulted.
Flap Debridement Terminology
Flap debridement was a surgical procedure. During the treatment of the skin flap, for example, when the skin flap was infected, necrotic, or other conditions that affected its normal function and healing. The main operation was to remove the scar tissue, necrotic tissue, foreign bodies, and possible sources of infection around the flap, creating good conditions for subsequent flap repair and healing. For example, in the treatment of some patients with scalp defects and titanium mesh exposure, the patient was first treated with emergency debridement after admission. After the wound was cleaned, debridement and flap repair were performed. The debridement involved the cleaning of the flap related tissues.
The best operation time for debridement
Generally, it was better to debride and suture wounds within 6 - 8 hours. For wounds with less pollution, debridement and suturing were generally carried out within 24 hours. For wounds on the head and face, debridement and suturing were generally carried out within 24 - 48 hours after the injury. However, this was only a general situation. It still needed to be judged according to the specific conditions of the wound, such as whether the injured tissue could be sutured without tension, the degree of wound contamination, the patient's own condition (including age, blood vessel condition, whether there was diabetes, immune function, blood clot function, etc.), and so on. If the wound is more contaminated, debridement should be carried out as soon as possible.
The best time for the second debridement
The best time for the second debridement should be determined according to the specific conditions of the wound or sore. If the wound or sore surface is small and the infection is not serious, the second debridement is generally carried out 2 - 3 days after the first debridement. If the wound or sore surface is large and the infection is serious, the debridement may be carried out every day or every other day until the infection is controlled. If the wound or sore surface has begun to heal, the debridement interval can be extended appropriately, usually 3 - 5 days. In addition, under normal circumstances, the debridement time for skin wounds was within six hours, and the debridement time for scalp lacerations was generally within twelve hours. For wounds with serious pollution, a second suture could be performed after debridement.
What kind of surgery is debridement and drainage
Debridement and drainage was a surgical procedure. For open contaminated wounds, debridement and drainage included the following contents: first, cleaning and deconstruction. It was divided into two steps: cleaning the skin and cleaning the wound. To clean the skin, the wound should be covered with sterile gauze and then wiped off the oil. Then, the soft brush should be dipped in disinfectant soap to scrub, and then rinsed with cold water. To clean the wound, the wound should be rinsed with normal saline to remove the dirt, blood clots, and foreign matter in the wound. The next step was to clean the wound. Anaesthetic was needed. After disinfecting the skin, the surgeon would clean the wound after re-preparation. The irregular skin border, deactivated tissue, and obvious contusion tissue around the shallow wound would be removed. The deactivated fascia and muscle would be completely removed from the deep wound. At the same time, the relevant fracture fragments and penetrating injuries would be dealt with. The active bleeding of the wound would also need to be dealt with. The last step was to repair the wound. After cleaning it with physiological salt water again, it was decided whether the wound should be opened or sutured according to the degree of contamination, the size and depth of the wound, and whether it should be sutured in one stage or delayed. During the suturing, attention should be paid to avoid dead space and excessive tension, and the important blood vessels, tendons, and nerve trunks should be handled accordingly. Debridement and drainage of the liver can be performed for patients with subhepatic capsule hemorrhage and infection, as well as firearm penetrating injuries with serious liver tissue damage. Skin debridement and drainage were used to remove the contamination and inflammatory substances in the skin wound, reduce the risk of infection, and keep the wound moist to facilitate the growth of tissue. It included preparation, cleaning the wound, disinfecting the wound, debridement, placing a drainage tube, bandaging the wound, and changing the dressing. It should be performed by professional medical staff.
The best time for debridement of contaminated wounds
For wounds with light pollution, the best time for debridement was generally no more than 12 hours, and for wounds with heavy pollution, the best time was no more than 6 - 8 hours. However, for wounds that had not been infected for more than 8 hours, if the patient was in good condition, debridement could also be performed. The local blood supply of the head and face wound was good, and debridement could still be performed 12 hours after the injury according to the contaminated wound. Generally, debridement and suturing could be performed within 24 hours, and debridement and suturing could also be performed within 24 - 48 hours after the injury.

What are the requirements and requirements for photography?
There were many requirements for light in photography: ###1. How to use light 1. ** Prominent main body ** - The main body was separated from the background by a reasonable lighting arrangement. For example, the background light was placed on the back of the character to make the character stand out in the dark background. The focus was on key parts such as the character's eyes. He could also use the cover to control the range of light to highlight specific parts of the body. - He adjusted the distance between the light source and the main body. When the light source moved closer to the main body, the main body would stand out from the background, and the relationship between the main body and the background would be changed by using the characteristic of light decay. 2. ** Creating an atmosphere and artistic effect ** - The backlighting on the side of the image could make the subject appear less bright and more dark. It was a good display of layering and three-dimensional sense, creating a unique sense of space, such as making the scene appear near dark and far bright, near thick and far light transmission effect. Although it was not easy to master the backlighting, it could be used to shoot silhouettes or to make translucent effects on petals, leaves, butterflies, etc. for artistic effects. - Precise control of the intensity of light and shadow, the transition between light and dark, like making the picture like an oil painting, can show different texture, such as when the fingertips are the brightest and include details such as dust in the air, can create a unique picture texture. ###2. Choice of Light Type 1. ** The characteristics and applications of different light directions ** - ** Straight Light **: The direction of the light is the same as the direction of the photographer's camera. It could illuminate the surface of the subject evenly and show details, but the light was hard and the shadows were obvious. It was suitable for shooting on cloudy or cloudy days to obtain a soft effect. The color reproduction was relatively good when the light was smooth. - ** Side light **: From the left or right side of the subject, at a 90-degree angle with the subject and the camera. It can present a strong contrast between light and dark, showing the subject clearly. It is often used for still life, scenery, and character photography. - ** Side Backlight **: From the back of the subject, maintaining a 135-degree angle with the lens. It can show the effect of less light and more darkness, showing a layered and three-dimensional feeling, making the picture more spatial. - Backlight: It comes from the back of the subject and is opposite to the direction of the lens. It is easy to cause exposure problems for the subject. It is rarely used except for shooting silhouettes or special artistic effects, but it can produce a translucent effect. - ** Headlight **: It comes from above the subject and is basically vertical to the subject. It has a large contrast and a hard tone when it shines on the subject. It is only used in special scenes to achieve visual effects. - ** Front light **: 45 degrees angle to the character, a light that is often used in shooting. 2. ** The characteristics and applications of different light sources ** - ** Natural Light **: The light that the sun shines on the ground. In the morning and evening, the brightness was weak, the contrast was small and soft, suitable for portrait shooting; in the afternoon, the brightness was strong, and the contrast between light and dark was large, suitable for shooting Taobao and advertising blockbusters with a small aperture and low IQ. Under natural light, the shutter speed should not be higher than 1/60 (considering the camera shake and focal length). - ** Flash (Artificial Light)**: Illuminated by artificial lights. The shutter speed was generally 1/125, and must not be lower than 1/250, otherwise the photo might be completely black. ###3. Quality control of light 1. ** The softness of the light ** - The larger the area of the light source, the softer the light, and the smaller the area of the light source, the harder the light. For example, wide natural light (such as cloudy or foggy, the entire sky is equivalent to a large soft light box) or artificial light (such as adding a diffusing device in front of the flash, using translucent plastic sheets, white cloth, etc. to soften the light) can reduce shadows, reduce contrast, and fade the texture. - The farther the light was, the softer it was, and the closer it was, the harder it was. The softness of the light can be changed by adjusting the distance between the light source. - Reflected light has a softening effect. It can reflect the concentrated light source to a wide, dull surface (such as a wall, ceiling, or a dull reflective board) to scatter the light. Matte surfaces reflect light more scattered than bright surfaces. Mirrors reflect light the most concentrated. 2. ** Light intensity (strong or weak) control ** - When the light is strong (such as the noon sun), you can use a small aperture and a low IQ to improve the clarity of the photo; when the light is weak (such as morning or evening light), it is suitable for portrait shooting. ###4. The relationship between light and color 1. ** White balance (light color) adjustment ** - You can use AWB outdoors. Take a few shots of the scene and let the camera automatically find the right white balance. The K value of indoor photoshoots could be adjusted by oneself. The K value of normal skin color was generally around 5000. Above 5000, the skin color was warm and suitable for bright colors and clothing. Below 5000, the skin color was cold and suitable for simple and elegant scenes and dark gray clothing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
