1.Touch method Use the fingertips of the index fingers of both hands to gently place the abscess at an appropriate distance, and then press with one finger a little harder, and the end of the other finger will have a fluctuating sensation, which is called a finger. After repeated tests and alternating left and right tests, if it should be pointed out as pus.
2.The doctor covers the affected finger (toe) with his left hand, and at the same time puts the flashlight under the affected finger (toe) with his right hand, aims at the affected finger (toe), and then pays attention to the upper surface of the finger (toe), if he sees a dark black shadow, it is pus. Pus accumulates in different areas, and its shadows can be seen in their corresponding areas. This method is suitable for identifying pus under the nails of the fingers and toes, because the local tissues are thin and transparent. If pus accumulates behind the root of the nail in the snake's eye, a slight darkening may be seen at the base of the nailThe septicum is in the periosteal region, with an enhanced shadow along the stroke of the phalanges and is clearly defined;In the bones, there is a black obscuration along the bones and a distinct outline in the infected area;In the joints, there is little shading at the joints;Within the tendon sheath, there is a slight obscuration, which travels along the entire palmar surface of the fingers;Abscesses on the tips of all fingers, all fingers, are a prominent dark area.
Start planning my 2024 point pressure method on the fingers (toes), when there is little pus in the lesion, you can use the point pressure method, which is simple and easy to do. Use a small round blunt object such as the tail of a pin or a match head to gently press on the affected area, and if a localized severe pain point is measured, it is a suspicious abscess. 4.If the pus is not much and is located deep in the tissue, it is difficult to distinguish the pus by touch, and the syringe puncture method can be directly used to puncture and aspirate the pus, which can not only be used to identify the presence or absence of pus, determine the depth of the abscess, but also collect pus samples for culture and drug susceptibility experiments. During operation, it must be strictly sterilized, and attention must be paid to the selection of needles of appropriate thickness, needle insertion angle, depth, etc. Select the obvious pain point as the puncture point, and after local anesthesia, the needle is inserted under negative pressure, and the abscess is sucked while entering, and if the pus is suctioned out, the abscess site can be determined. If there is no pus in one puncture, the puncture can be repeated.
bUltraultrasound is characterized by simple operation and no injury, which can accurately determine the location of the abscess and assist in judging the size of the abscess, so as to guide puncture or incision and drain pus.
