Perioperative period

Perioperative period is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Perioperative period rather than just read about it. In short: The perioperative period is a period of a patient's surgical procedure. The period may include the three phases of surgery (preoperative, intraoperative, and postoperative), though it is a term most often used for the first and third of these only.

Key takeaways

Perioperative period belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Perioperative period to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Perioperative period from memory before moving on to harder problems.

Reference excerpt

The perioperative period is a period of a patient's surgical procedure. The period may include the three phases of surgery (preoperative, intraoperative, and postoperative), though it is a term most often used for the first and third of these only. It commonly includes ward admission, anesthesia, surgery, and recovery. Perioperative care is the care that is given before and after surgery. The primary concern of perioperative care is to provide better conditions for patients before an operation (sometimes construed as during operation) and after an operation.

Perioperative care The perioperative period is a period of a patient's surgical procedure. It commonly includes ward admission, anesthesia, surgery, and recovery. Perioperative may refer to the three phases of surgery: preoperative, intraoperative, and postoperative. More commonly, the term is used for the first and third of these only, as a term which is often specifically utilized to imply around the time of the surgery. Perioperative care is the care that is given before and after surgery. The primary concern of perioperative care is to provide better conditions for patients before an operation (sometimes construed as during operation) and after an operation. The care takes place in hospitals, in surgical centers attached to hospitals, in freestanding surgical centers, or health care providers' offices. Findings from a systematic review of perioperative advance care planning suggest the importance and value that various types of decision aids have for patients to clarify their goals and specify others who can make decisions for them in case of unexpected surgical difficulties.

Phases

Preoperative The preoperative phase is used to perform surgical clearance, attempt to limit preoperational anxiety, and may include the preoperative fasting. This period prepares the patient both physically and psychologically for the surgical procedure and after surgery. For emergency surgeries, this period can be short and the patient may be oblivious to this; for elective surgeries preops, as they are called, can be quite lengthy due to a multitude of factors, including surgical clearance. Information obtained during preoperative assessment is used to create a care plan for the patient.

Intraoperative The intraoperative period begins when the patient is transferred to the operating room table and ends with the transfer of a patient to the post-anesthesia care unit (PACU). During this period the patient is monitored, anesthetized, prepped, and draped, and the operation is performed. Nursing activities during this period focus on safety, infection prevention, opening additional sterile supplies to the field if needed and documenting applicable segments of the intraoperative report in the patients electronic health record. Intraoperative radiation therapy and intraoperative blood salvage may also be performed during this time.

Postoperative The postoperative period begins after the transfer to the PACU and terminates with the resolution of the surgical sequelae. It is quite common for the last of this period to end outside of the care of the surgical team. It is uncommon to provide extended care past the discharge of the patient from the PACU. When stable at PACU, the patient is usually admitted to the surgical ward for continued postoperative care and recovery. Postoperative recovery is commonly used as a concept and can mean different things in different contexts and to different actors such as healthcare professionals and patients. Postoperative recovery is an energy-requiring complex process of returning to normality and wholeness that starts immediately after surgery and continues long after discharge. For patients recovery includes different turning points such as regaining independence and control over physical, psychological, social, and habitual functions and well-being.

Worked examples

Example 1 — a first encounter with Perioperative period

Start with the simplest possible case. Write down what Perioperative period claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Perioperative period before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Perioperative period ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Perioperative period

In research: Perioperative period appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Perioperative period in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Perioperative period is common in secondary-school and first-year university syllabi. It links to neighbouring topics Surgery, so understanding it makes those chapters shorter.
In everyday life: Look for Perioperative period outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
