Surgery is the treatment of disease, injury, or deformity by physical intervention — cutting, repairing, removing, or reconstructing tissue. But a nurse does not care for "a surgery"; a nurse cares for a person before, during, and after one. That whole journey — from the decision to operate through recovery — is called the perioperative period, and it has three phases:
- Preoperative phase: from the decision for surgery until the person is transferred to the operating room.
- Intraoperative phase: from entry into the OR until transfer to the post-anesthesia care unit (PACU).
- Postoperative phase: from PACU admission through recovery, whether that means days in the hospital or discharge home the same day.
This topic builds the map: how surgeries are classified, where they happen, who is on the team, how anesthesia works, and which factors raise risk.

Why this matters
- Surgery is common and high-stakes. Surgical safety depends on every team member understanding their role and the phases of care.
- Nurses work in every phase. Ward and clinic nurses prepare patients preoperatively; circulating and scrub nurses staff the OR; PACU and unit nurses manage recovery.
- Patient safety is built on communication. Wrong-site surgery, medication errors, and missed complications are often communication failures — the reason checklists and structured handoffs exist.

Core Concepts
Classifying surgery by purpose
Surgery is often described by its goal:
- Diagnostic: performed to find out what is wrong — for example, a biopsy to determine whether a suspicious growth is malignant.
- Curative (ablative): removes the problem — excising a tumor, repairing a perforated organ, removing an inflamed appendix.
- Restorative/reconstructive: repairs or restores function or appearance — repairing a fracture, rebuilding a joint.
- Palliative: relieves symptoms without curing the disease — debulking a tumor to reduce pain or obstruction in advanced cancer.
- Cosmetic/aesthetic: improves appearance at the person's request — rhinoplasty, breast augmentation.
- Transplant: replaces a failing organ or tissue with a donor organ.
One procedure can serve more than one purpose, and the purpose shapes what the nurse helps the person expect.
Classifying surgery by urgency
- Elective surgery Planned and schedulable; safe to wait Full entry → is planned and scheduled — it is beneficial but can wait without immediate danger (joint replacement, hernia repair). "Elective" does not mean "optional" — it means timing is chosen.
- Urgent surgery Needed soon to prevent deterioration Full entry → is needed soon — typically within hours to days — to prevent deterioration or complications (many fracture repairs, some cancer resections).
- Emergency surgery Needed immediately to save life, limb, or organ Full entry → must happen immediately to save life, limb, or organ (ruptured appendix, major trauma with hemorrhage).
Urgency drives the nursing approach: the elective patient has time for full preparation and teaching; the emergency patient may arrive with almost none, shifting the priority to rapid, safe stabilization.
Where surgery happens
Surgery occurs in inpatient settings (the person stays at least one night) and ambulatory/outpatient settings — same-day surgery units and freestanding centers where the person goes home the same day. Ambulatory surgery is still real surgery: the same anesthesia, the same infection risks, and a much shorter window for teaching and monitoring. Discharge teaching, a responsible adult at home, and clear follow-up instructions are safety essentials, not courtesies.
The surgical team
- Surgeon: performs the procedure and directs the surgical plan.
- Anesthesia provider (anesthesiologist or certified registered nurse anesthetist/CRNA): manages anesthesia — induction, monitoring the person throughout, and emergence. The anesthesia provider is the person's physiologic watchdog during the case.
- Circulating nurse: a registered nurse working outside the sterile field — coordinates the room, documents, obtains supplies, counts instruments and sponges, positions and protects the person, and advocates for safety.
- Scrub person (scrub nurse or surgical technologist): works inside the sterile field, handing instruments and maintaining sterility.
- PACU nurse: manages immediate recovery from anesthesia — airway, breathing, circulation, and pain.
Each role has a distinct scope; no one role covers another's responsibilities, and safety depends on all of them communicating.
Anesthesia basics
- General anesthesia Reversible drug-induced unconsciousness with no awareness Full entry →: the person is rendered unconscious, with no awareness, amnesia, and muscle relaxation; airway support is required. It is more than "sleep" — it is a reversible, drug-induced state maintained and monitored by the anesthesia provider.
- Regional anesthesia Numbing a region (spinal, epidural, nerve block) Full entry →: numbs a region of the body — spinal, epidural, or peripheral nerve blocks. The person may be awake, lightly sedated, or fully sedated.
- Local anesthesia: numbs a small area at the surgical site, often combined with sedation.
- Monitored anesthesia care (MAC): sedation and monitoring for procedures that do not require general or deep regional anesthesia.
Anesthesia choice depends on the procedure, the person's health, and provider judgment.
Factors that raise surgical risk
Risk is individualized, not categorical. Commonly considered factors include: age at the extremes of life; cardiovascular, pulmonary, renal, or metabolic disease (such as diabetes); nutritional status; smoking and alcohol use; medications that affect clotting or other systems; obesity; and reduced mobility. These factors increase the chance of complications like poor wound healing, infection, and bleeding — they do not mean surgery is impossible, just that the team plans around them (see Preoperative Phase).
Common Confusions
| Do Not Confuse | With | Difference |
|---|---|---|
| Elective surgery | Optional surgery | Elective means planned and schedulable — it can wait without immediate danger but may still be medically necessary |
| Urgent surgery | Emergency surgery | Urgent must happen soon (hours–days) to prevent deterioration; emergency is immediate to save life, limb, or organ |
| Outpatient/ambulatory surgery | Minor or low-risk surgery | Same-day discharge does not mean low risk; anesthesia and infection risks are real, and teaching is compressed |
| General anesthesia | Ordinary sleep | General anesthesia is a drug-induced unconscious state with amnesia and no awareness, requiring airway support |
| The surgeon | The anesthesia provider | The surgeon performs the procedure; the anesthesia provider manages anesthesia and physiologic stability |
Eli explains
The same idea, in plain words
Explain it like I’m 10
Surgery is like a planned road trip: you pack and check the car before leaving (preoperative), everyone does their job during the drive (intraoperative), and you arrive and unpack safely (postoperative). Some trips are planned weeks ahead, some are emergencies — but everyone always checks the same map so nobody goes to the wrong place.
Worked example
A nurse orienting to the surgical unit sorts today's cases:
- Ms. Ito is having a rhinoplasty she scheduled months ago. Purpose: cosmetic. Urgency: elective — it can wait without harm.
- Mr. Barnes has a colon tumor bleeding slowly; surgery is scheduled within two days. Purpose: curative (removing the tumor) with palliative elements (stopping the bleeding). Urgency: urgent — prompt, but with time for preparation.
- Ms. Adeyemi arrives by ambulance with a ruptured ectopic pregnancy and falling blood pressure. Purpose: curative/emergency control of hemorrhage. Urgency: emergency — minutes matter, and preparation happens in parallel with stabilization.
Same hospital, three different nursing challenges. Classification is not trivia — it tells the nurse how much time, teaching, and preparation are possible before the person reaches the OR.
Key takeaways
- The perioperative period has three phases — pre-, intra-, and postoperative — and the surgery itself is only the middle part.
- Classify by purpose (diagnostic, curative, restorative, palliative, cosmetic, transplant) and by urgency (elective, urgent, emergency).
- Elective ≠ optional, and urgent ≠ emergency (urgent is hours–days; emergency is immediate).
- Ambulatory surgery is still real surgery with real anesthesia and infection risks; discharge teaching and a responsible adult at home are safety essentials.
- Know the team roles: surgeon (procedure), anesthesia provider (anesthesia and physiologic stability), circulating RN (outside the sterile field), scrub person (inside the sterile field), PACU nurse (immediate recovery).
- General anesthesia is more than sleep — it is a reversible unconscious state requiring airway support and continuous monitoring.

6 review questions from the chapter. Try each one, then open the answer.
What are the three phases of the perioperative period, and where does each begin and end?
Show answer
Preoperative: from the decision for surgery until transfer to the OR. Intraoperative: from OR entry until transfer to the PACU. Postoperative: from PACU admission through recovery to discharge.
Explain the difference between elective, urgent, and emergency surgery.
Show answer
Elective: planned, can wait without immediate danger (not "optional"). Urgent: needed soon to prevent deterioration. Emergency: immediate, to save life, limb, or organ.
A patient has surgery to remove a tumor that is causing pain but cannot be cured. How would you classify this surgery by purpose?
Show answer
Palliative — the goal is symptom relief, not cure. (It could also be described as debulking.)
What is the difference between the circulating nurse's and the scrub person's roles regarding the sterile field?
Show answer
The circulating nurse works outside the sterile field (coordinating, documenting, counting, advocating); the scrub person works inside the sterile field, handing instruments and maintaining sterility.
Why does ambulatory (same-day) surgery still require serious safety attention?
Show answer
Same-day surgery still involves anesthesia, invasive procedures, and infection risk, with a compressed window for monitoring and teaching — discharge criteria, a responsible adult at home, and clear follow-up are safety essentials.
List three factors that can raise a person's surgical risk.
Show answer
Any three: age extremes, cardiovascular/pulmonary/renal/metabolic disease, poor nutrition, smoking, alcohol use, medications (e.g., anticoagulants), obesity, reduced mobility.
