How do the operations? Indications, training and types. How much do the operation?

Although it is believed that the body is a complex self-regulating system, sometimes it can not do without surgical intervention. In the animal world, the rule of natural selection operates - the survivor is the one who is stronger, more enduring, healthier. Human life is expensive to put such experiments. Therefore, people with serious failures of the body's work are resolved for surgical intervention to correct the painful condition. Before doing the operations, we weigh the pros and cons, given the chances of improvement and the risks of negative consequences.

Necessity

The decision to conduct a surgical intervention is made taking into account the indications. They can have a relative nature - to touch on the issues of correction of a painful condition that are not of extreme necessity - and absolute - to respond to threats associated with a real and obvious danger to life. Postpone such operations can only be in the presence of agony in the patient.

In determining the testimony, the rationale for the urgency of the intervention is usually immediately given. At this stage, they are determined with the possibility of holding it. The operating conditions, the availability of the necessary equipment and tools, the possibility of additional examination, the taking of biomaterials for analyzes are taken into account.

Even if the doctor has confidence that it is necessary and possible to do the operation, he must obtain permission from the patient or the persons representing him (unconsciousness, limited capacity). In some cases, if the patient's life threatens and if his personality can not be established, the doctor may not wait for the official consent.

Diagnostics

Ideally, every patient should undergo a detailed medical examination to understand whether it is possible to perform surgery on the available indications. In general, a standard commission survey is conducted. At the reception, the patient declares the presence or absence of complaints of well-being.

If there are existing problems with health, additional tests are prescribed. In some cases, a complete blood count and radiography will be sufficient. In others, you may need the results of additional tests, electrocardiography data, ultrasound diagnosis, MRI, and specific tests.

Regardless of the quality of the preoperative preparation, the patient is examined by an anesthesiologist before the intervention with general anesthesia. Additionally, the absence of contraindications associated with respiratory, cardiovascular, and psychiatric disorders is checked.

Risks

Any interference in the activity of systems and organs of a living organism to a certain extent borders on the risk of irreversible consequences or critical violations of their functions. Modern diagnostics and methods of operation minimize them, but such variants must also be taken into account before deciding whether to perform an operation or to restrict oneself to only conservative treatment methods.

The principle of surgery - tissue separation - involves the presence of physiological and psychological trauma. It can be expressed more or less, but still a certain period for recovery is required. And although they try to follow the principle when determining the risks, so that the operation is not more dangerous than the consequences - sometimes you have to grab any opportunity to get rid of the ailment.

Types of intervention

The operation is understood as the complex medical effect on the patient's body (its tissues and / or organs) in order to correct its painful condition or additional diagnosis. In most cases, such intervention occurs after the opening of the outer skin with a special tool. Recently, it has become possible to operate with the use of new high-tech equipment. Electrocoagulation, wave radiofrequency, laser radiation, cryosurgery, ultrasound may be used.

There are simple operations that can be carried out on the basis of outpatient departments, and complex, requiring a special room (operating unit). In different cases, the number of medical personnel will differ (surgeon, assistant, anesthesiologist, nurse, nurse).

How do the operations to correct dislocations? In such cases, tissue separation is not necessary. Correction of the condition is carried out without the aid of a surgical instrument (manual manual).

How much do the operation

Surgical intervention can last minutes or stretch for hours. Everything depends on the type, purpose, complexity of the procedure. When you have to operate for several hours in a row, the surgeons' teams work in shifts so that the doctors can relax. In special cases, additional specialists from adjacent areas may be recruited if in the process of performing the basic procedure a highly specialized consultation is required.

Some operations are done under general anesthesia, others - under local anesthesia. If the impact is insignificant and transient (pulling out a loose tooth), it is possible to refuse anesthetic at all. The total duration of the intervention also depends on the time of the preparatory and final procedures. There are times when the main impact takes a minute, but it takes a lot longer to gain access to the hearth.

Also, the duration can be affected by how the operations are done. The basic principle is that the cut is made as small as possible, but that it provides an operational space. If everything goes according to schedule - this is one thing, but often there are unforeseen situations, complications (bleeding, shock). There is a need to prolong the action of anesthesia or anesthesia to remove the patient from a critical condition, stopping the wound, completing the operation.

Stages

There are three main points in the course of operative surgical intervention. First, you need to expose the organ or hearth (provide access). This is followed by the main procedure associated with various kinds of manipulations with the instrument or equipment (operational reception). It can be different in complexity, nature, type and method of exposure. At the final stage (operative output), the integrity of damaged tissues is restored. The wound is sewn tightly or a drainage hole is left.

The organization of the surgical operation begins with the installation of the prepared patient (sanitization) on the operating table. The expediency of location is determined by the surgeon, he also chooses the instrument, the option of operative access, reception and exit. Depending on what operations are being performed, the procedure can be performed in any suitable position and not necessarily on the table. Anesthesiologist provides anesthesia, assistant helps during the intervention, the operating sister is responsible for the instrument and materials, the nurse provides the proper level of cleanliness.

Kinds

From the way operations are performed, primary and repeated (after complications) are distinguished among them. Surgical intervention can be radical, aimed at the complete elimination of the causes or consequences of pathologies, or palliative (partial solution of the problem). If it is not possible to solve the problem, intervention is made to alleviate the patient's condition (symptomatic intervention).

They can be urgent by the time (immediately when the diagnosis is made according to the indications), urgent (during the first hours after admission to the hospital), planned against the background of a normal general condition (without a specific period, according to the patient's readiness). It is also possible to identify interventions associated with violations in the integrity of tissues or organs (bloody), and bloodless (crushing stones); Purulent (abscesses) and aseptic (pure).

The nature of the localization is distinguished: cavitary (peritoneum, thorax, cranium) and superficial (skin). And also: on soft tissues (muscles) and bone (amputations, resections). From the type of tissue over which the surgical procedure is performed: neurosurgical, ophthalmic, plastic and so on.

By the type of the organ to be affected, and the surgical procedure, the name of the surgical operation is determined. For example, appendectomy - removal of the appendix; Thoracoplasty - elimination of defects and so on.

What to do after surgery

Depending on the complexity of the intervention, the surgeon decides whether to further monitor the patient. With an easy degree, he can be released home or sent for observation by a district therapist. They can be transferred to a regular ward or intensive care unit, delivered to the intensive care unit. In any case, for a full recovery, a rehabilitation period is needed.

Depending on the complexity of the intervention, it can have a different length and include a wide range of procedures: physiotherapy, massage, preventive physical education. This stage is aimed at restoring the tone of atrophied muscles after prolonged bed rest or, for example, to increase the motor activity of the damaged joint. In each specific case, a certain task is posed, which can be achieved by various methods. The main goal - the restoration of the body's functions, providing a normal lifestyle.
