open hand trauma
Introduction
Introduction to open hand trauma The hand is most exposed to the outside world and is most vulnerable to injury. In orthopaedic emergency patients, hand injuries account for about a quarter of the number of visits, while open hand injuries account for two-thirds of total hand injuries. Prevention and treatment of hand injuries is an important issue in the field of surgery. In particular, emphasis must be placed on the early treatment of complex emergency hand injuries, which must be positive. If the early treatment is correct, it can avoid the second-stage operation. If the injury is serious and can not be repaired early, it should also try to create conditions for late repair in early surgery. The disease is caused by traumatic factors, and the injury factors are various, such as object bruises, knife wounds, glass cuts, machine bruises and gunshot wounds, etc. can cause open hand injuries. basic knowledge The proportion of illness: 0.02% Susceptible people: no specific population Mode of infection: non-infectious Complications: swelling, traumatic arthritis
Cause
Open hand injury cause
The disease is caused by traumatic factors, and the injury factors are various, such as object bruises, knife wounds, glass cuts, machine bruises and gunshot wounds, etc. can cause open hand injuries.
Prevention
Open hand injury prevention
The disease is caused by traumatic factors, so paying attention to production and life safety is the key to prevent this disease. In addition, we must pay attention to the strict implementation of various nursing measures before and after surgery, pay attention to psychological care, and closely observe the changes in the condition to do pain relief care. Functional exercise, guide the patient to nurse, prevent joint stiffness.
Complication
Open hand trauma complications Complications, swelling, traumatic arthritis
Hand trauma can occur in patients with hand injury, severe cases can be manifested as massive bleeding and affect blood circulation, resulting in swelling of the affected limb, patients who do not pay attention to early exercise after surgery, may be complicated by tendon and joint adhesion, resulting in dysfunction, severe cases Causes joint stiffness and traumatic arthritis. In addition, the most common complication of open hand trauma is infection. The main causes include: mechanical wounds, severe tissue collapse caused by crush injury, and indistinguishable tissue. Debridement is not complete.
Symptom
Open hand trauma symptoms Common symptoms Motor dysfunction edema wrist long bone spur thumb finger gestation dysfunction arm muscle atrophy hand acid traumatic bleeding open injury finger injury bacterial infection
The main manifestation of this disease is bleeding at the wound, which can be manifested as dysfunction of the affected limb when combined with bone and nerve damage. Another major problem is infection caused by trauma, open injury caused by direct violence, according to its pathological changes. Third District:
The center of the outermost surface is the first zone, which is in contact with the wounds and air and is the main contaminated area. Surrounded by the second district, the layers of tissue are torn, squeezed, and frustrated by violence, causing tissue necrosis, loss of vitality of the cells, and removal of the cells during debridement. The outer periphery is the third zone, that is, the tissue turbulence reaction zone. Due to the turbulent turbulence of the violent, the tissue edema, the exudation increases, the vasospasm, the cell viability is reduced, and if the infection does not occur, the vitality can be restored, and the debridement is thorough, that is, The District 2 organization is removed, but only if it is clear whether the organization is inactivated or not, can we make a decisive decision.
Examine
Open hand injury examination
The disease can be diagnosed according to the symptoms of the affected area, and no other auxiliary examination method is needed. Only when the patient is suspected of having other injuries, such as fractures and nerve damage, other examination methods are needed to help the diagnosis. X-ray examination, functional examination of the affected limb, etc.
Diagnosis
Open hand injury diagnosis and identification
The disease has a clear history of trauma, and can be clearly diagnosed from the patient's symptoms and performance, without the need for differential diagnosis, but should pay attention to whether open hand injury combined with other injuries, such as fractures and nerve damage.
