Perioperative medicine

Perioperative medicine is a biology 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 medicine rather than just read about it. In short: Perioperative medicine is the medical care of patients from the time of contemplation of surgery through the operative period to full recovery. Perioperative care may be provided by an anesthesiologist, intensivist, internal medicine generalist or hospitalist working with surgical colleagues.

Key takeaways

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

Reference excerpt

Perioperative medicine is the medical care of patients from the time of contemplation of surgery through the operative period to full recovery. Perioperative care may be provided by an anesthesiologist, intensivist, internal medicine generalist or hospitalist working with surgical colleagues.

Background Perioperative medicine encompasses the care of the patient preparing for, having and recuperating from surgery. In the practice of perioperative medicine the surgeon, anesthesiologist, intensivist and medical consultant work in concert. The medical knowledge distinct to this field includes that of operative risk and complications, of patient specific risks, of methods to reduce risk, and of the management of medical illness during this time period. Evidence supporting best practices in perioperative medicine is expanding, though historically this field has been directed by common practice and experience. It remains a field governed primarily by the art of medicine. Notably, in the last decade, there has been a concerted effort by various anesthesia representative bodies to incorporate greater teaching into management of patients during the perioperative period. Specifically, annual summits have been held in the UK and US for a number of years, various courses exist to encourage this field of medicine and there is a PubMed listed journal dedicated to the field of Perioperative Medicine.

Worked examples

Example 1 — a first encounter with Perioperative medicine

Start with the simplest possible case. Write down what Perioperative medicine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 medicine 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 medicine 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 medicine

In research: Perioperative medicine appears in biology 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 medicine 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 medicine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anesthesiology, Hospital medicine, Surgery, so understanding it makes those chapters shorter.
In everyday life: Look for Perioperative medicine 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.

Frequently asked questions

What is Perioperative medicine in simple terms?

Why does Perioperative medicine matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Perioperative medicine?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
