Surgical operation is the culmination of treatment, but success depends on more than just masterly knife-work. In this chapter, we analyze the entire cycle of a surgical intervention: from determining indications and assessing operative and anesthetic risk to smooth patient management up to discharge.
The section covers the classification and stages of operations, gold standards of preoperative preparation, and infection prevention. Special emphasis is placed on the postoperative period. You will learn how to properly manage postoperative pain syndrome and prevent life-threatening conditions: early bleeding, thromboembolic complications, development of pressure ulcers, and late problems in the surgical area.
In practical classes and exams, risk assessment scales, PE prophylaxis algorithms, and management of early postoperative complications are tested most rigorously. This is not just academic theory, but the foundation of clinical thinking for a physician of any surgical specialty.
What is the main difference between an exploratory operation and a diagnostic one?
A diagnostic operation is initially planned to establish or clarify a diagnosis (e.g., taking a biopsy). An exploratory operation was planned as radical and therapeutic, but during the procedure it turned out to be impossible to perform due to advanced disease progression (e.g., an inoperable tumor).
When is the surgical field prepared?
Skin preparation with antiseptic solutions begins strictly after the patient has been anesthetized or local anesthesia has been performed.
What is included in the concept of the preoperative period?
This is the time interval from the moment the patient is admitted to the medical facility until the actual start of the surgery.
Which anesthesia method is considered basic and preferred?
Neuroleptanalgesia (NLA) is indicated as the preferred method. However, the selection principle is always strictly individual — for instance, halothane is preferred in asthma.
At what point does preoperative preparation begin?
From the patient's first contact with a medical worker, such as a polyclinic doctor or an ambulance crew.
Are antibiotics always necessary for "clean" surgical operations?
In most cases, antibiotic prophylaxis for type I operations is inappropriate. An exception is made for immunocompromised patients and during the placement of prostheses (artificial joints, vascular shunts), where the consequences of infection are catastrophic.
