Chapter 20: Postoperative Nursing Care

Welcome to Last Minute Lecture!

This free chapter overview is designed to help students review and understand key concepts.

These summaries supplement not replaced the original textbook and may not be redistributed or resold.

For complete coverage, always consult the official text.

Okay, let's unpack this.

Imagine the patient just wheeled out of the operating room.

That critical moment immediately after surgery is where your mission as a nurse truly begins.

What's the absolute first thing on your mind?

That's right.

Today our deep dive is into post -operative care, focusing on the nurse's vital role in guiding a patient's recovery from those intense first hours in the post -anesthesia care unit, the PACU, all the way to discharge.

This isn't just about what happens post -op, but what you do about it.

And for you, the nursing student, we're taking a deep dive into Lewis's Medical Surgical Nursing 12th Edition.

Consider this your shortcut to understanding the chapter, kind of custom tailored to give you those high -impact, need -to -know insights quickly and clearly.

Exactly.

We'll be navigating this complex landscape through seven conceptual pillars.

Gas exchange, fluids and electrolytes, infection, pain, perfusion, safety, and tissue integrity.

Okay.

These aren't just academic terms.

They're really the lenses through which you'll assess, prioritize, and intervene.

Our mission today is to walk you through the pathophysiology, pinpoint those critical risk factors and clinical manifestations, and most importantly, highlight the nursing management strategies for the most common post -op challenges.

We'll connect it all with straightforward language and real -world examples, keeping you focused on the essential nursing process.

Let's jump straight into the PACU.

This unit is strategically located near the operating room for swift patient transfer.

Its core goals are simple.

Keep the patient safe as they recover from anesthesia,

identify any immediate problems related to the surgery or anesthesia, and then intervene decisively.

It's really a place of vigilant assessment and quick action.

And that transition into the PACU is, well, it's a prime example of collaborative care.

You've got the surgeon, the anesthesia care provider, the ACP, and the OR nurse all contributing to a comprehensive handoff report to you, the PACU nurse.

Okay.

This smooth transfer helps determine the patient's phase of post -anesthesia care.

Right.

And the journey through post -anesthesia care is typically broken into three phases.

Phase -on is for immediate intensive care.

We're talking continuous ECG monitoring, frequent blood pressure checks, sometimes even mechanical ventilation.

The most intense phase.

Exactly.

The goal is stability for transfer to phase two, an inpatient unit, or maybe the ICU.

Then phase two primarily serves ambulatory surgery patients or those who fast track bypassing phase I due to rapid recovery.

The aim here is getting them ready for home or an extended care facility.

Makes sense.

And finally, extended observation is for continued monitoring after phase on or two, just making sure they're ready for self -care.

A critical element in all this is the PACU handoff report itself.

It really should be standardized and interactive, not just a data dump.

It allows you to ask crucial questions.

Right.

P categories include general patient info, their medical history,

detailed intraoperative management think and aesthetic agents,

fluids given, urine output, and the intraoperative course, like any unexpected events.

Many units use tools like SBAR, that's situation, background assessment, recommendation, to make sure nothing gets missed in this vital communication.

Good point.

So after that handoff, you launch into your initial PACU assessment.

This is where your critical thinking becomes your best tool.

You always start with airway, breathing, and circulation, your ABC.

Absolutely fundamental.

Is the airway patent?

What's the rate and quality of respirations?

Are breath sounds clear?

Pulse oximetry and capnography are your vital tools here for assessing oxygenation and ventilation.

Why first?

Well, because without effective ABCs, nothing else matters, right?

Exactly.

For circulation, you're monitoring the ECG for heart rhythm, blood pressure, temperature, capillary refill, skin condition, and checking those peripheral pulses.

Then a thorough neurologic assessment,

level of consciousness, orientation, sensory and motor status, and pupil reaction.

And here's a clinical pro you should remember.

Hearing is often the very first sense to return in an unconscious patient.

Oh, interesting.

Yeah, so always explain what you're doing, even if they seem unresponsive.

If regional anesthesia was used, you'll assess dermatome levels, those specific skin areas linked to spinal nerves, to track the return of sensation and movement.

It usually comes back farthest from the injection site first.

Got it.

Beyond ABCs and neuro, you're assessing the urinary system and fluid balance.

Yeah.

And you know, intake and output, checking IVs, any drains.

A quick but thorough look at the surgical site dressings.

Drainage is essential.

Then the gastrointestinal system for nausea, vomiting, and listening for early bowel sounds.

Paid assessment is paramount, of course.

Absolutely.

And finally, overall patient safety, thinking about proper positioning and fall risk.

Okay, now that we've covered that crucial initial assessment, let's connect the dots to some of the most common postoperative problems you'll encounter on the clinical unit.

We'll explore their causes, how they present, and your critical nursing interventions.

Yeah, let's make this really tangible.

Let's keep EG in mind.

A 74 -year -old retired college professor, he's got type 2 cancer, and many of these complications are a real concern.

Perfect example.

Hashtag, tag, hashtag today.

Yeah.

Respiratory problems.

Yeah.

Okay.

Respiratory issues are always top priority post -op.

In the PCU, airway obstruction, often just from the tongue falling back, is pretty common.

Right.

Beyond that, hypoxemia, that's low blood oxygen, a PaO2 under 60 millimiller Hg, is frequently caused by atelectasis.

That's a collapse of the alveoli, the tiny air sacs.

It can happen from mucus plugging small airways or you know, not enough surfactant.

Okay, atelectasis.

And then there's hypoventilation, just slow, shallow breathing, which makes the low oxygen and high carbon dioxide situation worse.

And patients like EG are highly vulnerable, aren't they?

Things like general anesthesia being over 55, smoking EG smokes a pack a day, pre -existing lung issues like a COPD, obesity, even the type of surgery like airway, thoracic, or abdominal, all increase that risk.

Definitely.

You need to watch for agitation, confusion, or restlessness.

These are often early signs of inadequate oxygenation.

Subtle signs first.

Exactly.

Other clues include changes in vital signs like increased or decreased heart rate and blood pressure, dysrhythmias, or just a low SPO2 reading.

And a key takeaway here,

these subtle signs can escalate into an emergency much faster than you might think.

Vigilance is crucial.

So your nursing management starts with immediate assessment, airway patency, chest symmetry, respiratory effort, listening to breath sounds, and continuous pulse oximetry for interventions.

Proper positioning is vital.

Unconscious patients need that lateral recovery position to prevent aspiration.

Conscious patients benefit from being supine with the head of the bed elevated helps maximize lung expansion.

Oxygen therapy is often started too.

And for every patient promoting deep breathing and coughing, using an incentive spirometer for those sustained deep breaths and teaching diaphragmatic breathing are all critical to re -expand alveoli and mobilize secretions.

Don't forget teaching them to splint their incision with a pillow when coughing.

Good point.

Plus frequent position changes, early ambulation, making sure their pain is well managed, and good hydration.

It all contributes to lung health.

So for EG with his COPD and that O2 sat of 92 % on four liters nasal cannula, those orders for deep breathing, incentive spirometry, and his albuterol nebulizer are your direct tools to prevent atelectasis and pneumonia.

You're actively intervening.

It's Iceland.

Hashtag, tag, tag, tag, be cardiovascular problems.

Yeah.

Okay.

Moving to cardiovascular issues.

In the PCU,

hypotension, low blood pressure is often due to fluid or blood loss.

You always have to think about hypovolemic shock or hemorrhage.

Right.

The most common PCU issue.

It is.

Hypertension, on the other hand, can stem from pain, anxiety, maybe a full bladder, or even being cold type

dysrhythmias often signal hypoxemia or electrolyte imbalances.

On the general unit, fluid imbalances are common too.

You see fluid retention from the body's stress response hormones like ADH and ACTH telling the kidneys to hold on to water and low potassium, hypokalemia, often from GI losses can trigger arrhythmias for patients like EG, his age, his immobility from the hip surgery, venous thromboembolism, VTE.

Those blood clots are a major risk.

Absolutely.

And it could be fainting.

Yeah, that can happen too.

Often from postural hypotension when they first try to get up, especially if they're older or a bit dehydrated.

So nursing management here prioritizes frequent vital sign monitoring, like every 15 minutes in phase I, always comparing to their baseline.

Crucial comparison.

And you must allude the HCP for specific parameters, right?

Like a systolic BP under 90 or over 160, heart rate outside 60 or 120, a narrowing pulse pressure, or any concerning trends or new dysrhythmias.

You got it.

For hypotension, think oxygen, maybe IV fluid boluses, check the surgical site for bleeding and possibly vasoconstrictor drugs.

And for hypertension.

Try to remove the cause, give pain meds, help them void, fix any respiratory issues, or rewarm them if they're cold.

For dysrhythmias, identify and correct the underlying cause.

Okay.

Fluid balance.

Accurate INO, monitor electrolytes, check the hematocrit or HDT to look for blood loss.

For EG, his age, diabetes, and that hip replacement, put him squarely in the high risk category for VTE.

So what are we doing?

Well, your nursing care includes things like pneumatic compression boots while he's in bed and crucially safely getting him up to ambulate.

There's usually a protocol,

slowly raise the head of the bed, let him dangle his legs, monitor for dizziness before he tries to walk, safety first.

Makes sense.

Step by step.

Hashtag, tag, tag, tag, tag, tag, see neurologic and psychological problems.

All right.

Let's talk neuro and psych.

In the PAC, you might see emergence delirium.

That's restlessness, agitation, maybe shouting.

Yeah.

And the critical point here, always suspect hypoxia first for any sudden agitation.

Don't just assume it's the anesthesia.

Hypoxia first.

Got it.

Delayed emergence where they take a long time to wake up is usually drug related, but again, could be hypoxia Okay.

And on the unit?

On the unit, you might encounter post -operative cognitive dysfunction or POCD.

It's more subtle, a longer term brain fog with memory and concentration issues, more common in older adults like EG.

Right, the fog.

Then there's post -operative delirium, which is more acute, a fluctuating mental status change.

It can be triggered by severe pain, fluid imbalances, hypoxemia, certain drugs, or even sleep deprivation.

All definite risks for EG.

So your assessment covers level of consciousness, orientation, memory, sleep -wake patterns, and again, rule out hypoxia if they're agitated.

Absolutely.

Your interventions have to focus on patient safety.

Side rails up, call bell within reach, always using two identifiers before anything.

Standard safety.

For delirium specifically.

Use screening tools, provide assistive devices like glasses, hearing aids, clocks, calendars, really important for EG who has hearing difficulty.

Good point.

Encourage family presence if possible.

Though EG's situation as a widower highlights that this isn't always an option, right?

Yeah.

So focus on what you can control.

You should fluid balance, good nutrition, promote sleep, get them mobilizing early, and always provide emotional support.

Listen to them, talk to them.

That human connection is key.

Hashtag tag, hashtag tag D.

Pain and discomfort.

Okay, pain.

Probably the number one concern for patients post -op.

It can be from the incision, sure, but also muscle spasms, anxiety, even just positioning or having tubes and catheters in.

And movement often makes it worse, right?

Coughing, deep breathing, trying to ambulate.

Definitely.

Plus deep visceral pain can sometimes signal a complication.

And we can't forget other discomforts like nausea, all the noise in the hospital, or shivering.

So assessment first.

The patient's self -report is truly the most reliable indicator.

Use a standard pain scale, numeric or faces, assess them at rest and during activity.

What if they can't verbalize?

Question.

Then you look for non -verbal cues.

Restlessness, grimacing, changes in vital signs, and always identify the location of the pain.

Nursing management.

It ideally starts with a preoperative pain plan.

Post -op, multimodal analgesia is key, using different types of pain relief together, like maybe an opioid plus an NSA or acetaminophen.

The benefit being?

Reduced reliance on opioids, which means fewer side effects like sedation or respiratory depression.

Patient -controlled analgesia, PCA, is great for empowering patients.

But there's a safety alert.

Always, always meticulously double -check the orders and the pump programming.

Crucial check.

Other options include epidural analgesia or perineural local anesthesia, like bupivacane liposome, often called X -barrel, which gives extended relief right at the surgical site.

And non -drug approaches.

Absolutely.

Complementary therapies like music, massage, guided imagery, repositioning, distraction.

They all help.

And crucially, time the analgesics effectively.

Give them before painful activities like ambulation.

So for E .G., with his initial eight out of 10 pain and that PCA morphine order, you'd be assessing its effectiveness, seeing why he's still in pain and layering in other strategies, maybe acetaminophen on a schedule.

Exactly.

Multimodal approach.

Hashtag, hashtag, hashtag ease.

Temperature changes.

Temperature changes are another common thing.

Hypothermia, core body temp below 96 .8 Fahrenheit or 36 Celsius, is really frequent right after surgery.

Anesthesia messes with temperature regulation and ORs are cold.

And older patients like E .G.

are at higher risk.

Yes.

Along with females, patients who had long procedures or were already cool beforehand,

the complications are significant.

Vasoconstriction leading to hypertension, more bleeding,

impaired immune function, even increased risk of surgical site infections.

And shivering.

Shivering dramatically increases oxygen demand, which is bad news for someone already recovering.

On the flip side, you might see fever.

The timing helps clue you in.

Surgical site infection usually shows up three to four days post -op, respiratory infections earlier, UTIs related to catheters.

Right.

And you always have to keep malignant hypothermia or MH in the back of your mind.

It's rare, but it's a life threatening genetic reaction to certain anesthetics causing rapid temperature spikes and severe muscle rigidity.

So nursing management involves assessing temperature right away in PCU, then frequently if they're hypothermic.

Check skin color and temp too.

Yep.

Interventions for hypothermia start with passive warming, warm blankets, socks,

then active warming if needed.

Forced air warmers, heated mattresses, warmed IV fluids, but always be careful to prevent skin injuries with active warming devices.

Safety alert there.

Definitely.

Give oxygen if they're shivering.

Sometimes opioids can help stop the shivering too.

For MH, it's an emergency.

Dantrolene is the antidote, plus rapid cooling and correcting acid base issues.

And for fever.

Meticulous aseptic technique for wound and IV care, promoting airway clearance to prevent lung infections, giving antipyretics, getting cultures if you suspect infection, and starting antibiotics if needed.

Hashtag, tag, tag, tag, estrointestinal problems.

Okay.

GI issues.

Postoperative nausea and vomiting.

PONV is super common.

High risk in females, nonsmokers, anyone with a history of motion sickness or previous PONV.

Anesthetics and opioids are big culprits too.

Then you have delayed gastric emptying and slowed

peristalsis, often from bowel handling during surgery or opioids.

This can lead to postoperative myelitis,

or POI, basically a temporary shutdown of bowel motility.

Common after abdominal surgery and in older folks like EG.

And just plain constipation.

Very frequent too.

Anesthetics, diet changes, immobility, opioids again.

Oh, and hiccups can happen too, usually from phrenic nerve irritation.

So assessment includes asking about nausea severity.

If they vomit, note the quantity, characteristics, color, check for abdominal distension, and listen carefully in all four quadrants for bowel sounds.

Right.

Return of normal motility is marked by passing gas or stool and being able to tolerate eating or drinking again.

Interventions.

5V fluids if they're NPO.

Once the gag reflexes back, start slow with clear oral fluids.

If a patient is still lethargic and vomits, get them into that lateral recovery position with suction ready to prevent aspiration.

Crucial safety.

Use anti -imetic meds for PONV and consider alternative therapies like aromatherapy or acupressure too.

For constipation, use bowel protocols, stool softeners, maybe laxatives, encourage ambulation, frequent repositioning, turning onto the right side can sometimes help gas pass.

What about POI?

Usually involves bowel rest initially, then gradually reintroducing food.

Sometimes an NG tube is needed for decompression.

And don't forget, critical oral care for any patient who is NPO.

It makes a big difference to their comfort.

Good reminder.

Hashtag tag G urinary problems.

Let's talk urinary issues.

Low urine output in the first 24 hours is actually pretty common.

It's often due to the body's stress response, fluid shifts, maybe fluid restriction before surgery or losses during surgery.

Okay, so not always alarming initially, but what is concerning?

Acute urinary retention.

That's when they can't void anesthesia, opioids, anti -cholinergic drugs, lower abdominal pelvic surgery, pain, immobility, even just being stuck flat in bed can all contribute.

Oliguria is specifically diminished urine output, less than expected, which could signal a kidney issue like renal ischemia.

So your assessment focuses on urine quantity and quality.

Output should be at least 0 .5 millibullers per kilogram per hour.

That's the general guideline.

Check catheter patency if they have one.

Most patients should void within about six to eight hours after surgery or after a catheter is removed.

And if they don't?

First, assess.

Use a bladder scanner to check for fullness,

or you can try percussing the bladder area for dullness indicating distension.

Then interventions.

Try non -invasive things first.

Promote normal voiding positions if possible.

Provide privacy.

Run water, offer drinking water, maybe warm water over the perineum.

Getting them walking to the bathroom or using a commode can help too.

And if those fail?

Intermittent catheterization is the next step, but only after you've confirmed bladder fullness with that bladder scan.

You want to avoid unnecessary catheterization because of the CIUTI risk catheter -associated urinary tract infections.

Right.

Intermittent cath preferred over indwelling, if possible.

Exactly.

Minimize that CIUTI risk.

Hashtag tag tag tag tag eight skin problems, surgical wounds.

Finally, let's look at skin issues, specifically the surgical wound.

The incision obviously breaches the skin barrier.

So healing and infection are major focuses.

SSI surgical site infections are a big risk.

They are often caused by bacterial contamination, maybe from the environment, the patients on skin flora or bowel contents and abdominal surgery.

Risk factors include things like malnutrition, immunosuppression, older age like EG, long hospital stays or procedures.

Diabetes too, right?

Like EG.

Yes.

Diabetes definitely impairs healing and increases infection risk.

Fluid accumulation under the incision can also impair healing.

And then there's wound decens where the wound edge is separate.

Sometimes you get a warning sign like a sudden gush of brownish pink or clear drainage.

So nursing management involves immediate post -op wound checks.

Frequently at first, like every 15, 30 minutes initially in PCU, you need to know the type, amount, color and odor of any drainage.

Drainage typically progresses from sanguineous, which is bloody, to serosanguineous, that's pinkish and watery.

Then finally to serious, which is clear or pale yellow.

You need to watch for signs of SSI, redness, swelling,

increasing pain or tenderness around the site,

fever or a high white blood cell count.

Who changes the first dressing?

Usually the healthcare provider, the surgeon or their team.

If the dressing gets saturated with drainage before then, you reinforce it with sterile gauze.

Don't remove the original dressing unless specifically ordered.

Be careful with drains, like Edie's Jackson Pratt Drain.

Note the drainage and avoid accidentally dislodging them.

And nutrition.

Absolutely crucial for wound healing.

Adequate protein and vitamins are essential.

For E .G.

with his diabetes and the J .P.

drain at his hip site, you'd be meticulously assessing that drainage and being super vigilant for any early signs of infection.

Hashtag, hashtag, three, two.

Discharge planning and special

Okay, so after addressing all these immediate and potential challenges, what does this all mean for getting your patient home safely and successfully?

It's not just about fixing problems, it's about preparing for discharge.

Exactly.

Discharge is guided by specific agency -approved criteria.

For phase I PCU discharge, patients generally need to be awake, have stable vital signs, no excessive bleeding or respiratory depression,

O2 saturation consistently above 90 % and have their pain and nausea reasonably controlled.

And for ambulatory surgery patients, those leaving from phase two or extended observation.

They need to meet all those phase I criteria.

Plus, they shouldn't have had any IV opioids within the last 30 minutes.

They need to have voided, be able to ambulate safely, have a responsible adult present to drive them home and help them.

And critically, they must understand their written discharge instructions.

You know, discharge planning isn't just something you do at the last minute.

It really is an ongoing process that should ideally start before the surgery even happens.

That's the ideal, yes.

Involving the patient and their caregiver early is key.

Provide both verbal and written instructions because people forget things when they're stressed or tired.

And using that teach back method is so important, right?

Having the patient or caregiver explain their care plan back to you, wound care, medication schedule, activity restrictions, when to call the doctor.

It's the best way to confirm they actually understand it.

Absolutely.

And for an older patient like EG, those gerontologic considerations are vital.

Their decreased respiratory function, like weaker cough, less chest compliance, makes them more prone to pneumonia.

Okay.

Altered vascular function, maybe some atherosclerosis, increases cardiovascular risks.

Their kidney liver function might be decreased, which heightens the risk of drug toxicity.

They also face an increased risk for postoperative delirium, influenced by age itself.

Baseline cognitive function, any history of alcohol use, hypoxia, metabolic imbalances, maybe hypotension during surgery, and polypharmacy, taking lots of medications.

Right.

And pain control can be tougher too.

It can be.

Pre -existing cognitive issues, impaired communication, sometimes fear of addiction.

It can make assessment and management tricky.

But the key thing to remember is untreated pain severely impacts recovery.

It's not something to just tolerate.

So as you, the listener, synthesize all this, think about EG again.

What specific elements would be absolutely crucial in his discharge teaching plan, given his age, his diabetes, a COPD, the recent HEPA placement, and that unique social situation being a widower with no local family support?

It changes things, doesn't it?

It absolutely does.

Support systems are a huge factor in successful recovery at home.

Hashtag, tag, tag, tag, outro.

Wow.

We've covered a tremendous amount in this deep dive into post -operative care.

From those really critical first moments in the PCU, through navigating these complex system -specific challenges,

your role as a nurse is just absolutely central to ensuring patient safety, comfort, and ultimately a successful recovery.

It's really about sharp assessment, timely intervention, and truly holistic care.

It's so much more than just checking boxes on a flow sheet.

Definitely.

And as you develop your nursing practice, just remember that every single journey through this post -operative period is unique.

It's shaped by their individual physiology, the specific surgery they had, and their own personal resilience.

So here's a thought to leave you with.

How will your deep understanding of all these interconnected systems allow you to anticipate challenges before they happen and really become a more proactive rather than just reactive advocate for your patients?

Great question.

Thank you for tuning into the deep dive.

Keep exploring, keep questioning, and keep deepening your knowledge.

You're making a profound difference out there.
