Preparing for Brachytherapy: Fasting, Bowel Preparation and the Anesthesia Check

The envelope from the radiation oncology department is thicker than expected. Inside: a map to the day-surgery entrance, a sheet headed “Nothing by mouth after midnight,” a second sheet about an enema, and a phone number for someone called the pre-assessment nurse. The treatment itself, a few small radioactive sources placed inside or against a tumor, will take an afternoon. The preparation, it turns out, takes a week of quiet attention.

Most people searching for how to prepare for brachytherapy are not frightened of the radiation. They are trying to make sense of three practical rituals that seem to belong to a different procedure entirely: fasting, bowel emptying and an anesthesia interview. Each has a specific job, and each makes more sense once you know what the team is protecting.

This explainer walks through those three tasks in the order you will meet them, then turns to the questions people quietly type into search bars afterward: does it hurt, must I lie still, and how soon will I feel like myself again.

What actually happens during brachytherapy

Brachytherapy is radiation delivered from inside the body rather than from a machine across the room. The word comes from the Greek for “short distance,” and that is the whole idea: a sealed radioactive source is placed in or beside the tumor so that the dose falls away steeply within millimeters, sparing nearby organs a large share of what external beam therapy would give them (Mayo Clinic).

Two broad formats exist. In high-dose-rate (HDR) treatment, hollow applicators or thin tubes are positioned first, usually under anesthesia, and a computer-controlled machine then drives a tiny source into them for a few minutes at a time before withdrawing it. Nothing radioactive remains in you between sessions. In low-dose-rate (LDR) treatment, most familiar from prostate “seed” implants, rice-grain-sized pellets are left in place permanently and release their energy over weeks to months while the surrounding tissue absorbs it (Cleveland Clinic).

The placement step is where preparation matters. For prostate implants, an ultrasound probe in the rectum guides needles through the skin behind the scrotum. For cervical or uterine cancer, applicators pass through the vagina. Breast, skin, esophageal and some head and neck tumors have their own routes. Imaging, often a CT or MRI with the applicators in place, lets physicists calculate exactly where the source should pause and for how long.

An empty stomach keeps anesthesia safe. An empty rectum keeps ultrasound images crisp and stops a gas-filled bowel from drifting into the high-dose zone. A thorough anesthesia check catches the medicine or heart condition that would turn a routine afternoon into a canceled one. Understanding how to prepare for brachytherapy is really understanding those three vulnerabilities.

Who brachytherapy is usually for, and who is usually asked to wait

Brachytherapy suits tumors that are reachable, reasonably well defined and close to tissue worth protecting. Prostate, cervical, endometrial, breast, skin, esophageal and some eye, lung and head and neck cancers are the common examples, and it may be used alone, alongside external beam radiation, or after surgery to treat the area where a tumor was removed (Mayo Clinic; Cleveland Clinic).

The decision is never made from a diagnosis label alone. The multidisciplinary team weighs tumor stage and grade, the exact anatomy on imaging, prior surgery or radiation to the same region, and whether the person can safely tolerate anesthesia and the positioning the procedure requires. Someone with a very large prostate gland, for example, may be advised toward hormone therapy first to shrink it, or toward a different technique, because needles cannot reach behind the pubic bone.

A short list of situations commonly leads to a pause rather than a refusal:

• An active infection, particularly a urinary or pelvic infection, which raises the risk of seeding bacteria along needle tracks.
• Recent changes to blood-thinning medicines that have not yet been settled with the prescribing clinician.
• Uncontrolled diabetes or a recent heart event that would make anesthesia less safe until reassessed.
• Pregnancy, which is excluded before pelvic radiation of any kind.
• Bowel that cannot be adequately emptied for imaging on the day.

Being asked to wait is frustrating, but it is usually a sign that the anesthesia or oncology team has found something fixable. Alternatives, including external beam radiation, surgery, systemic therapy or active surveillance for some low-risk prostate cancers, are discussed in the same clinic. The choice between them rests with you and your treating team, weighed against your own priorities.

How to prepare for brachytherapy: the week before

Preparation begins well before the fasting clock starts. In the seven days beforehand, most departments ask you to do four things, and each deserves a moment.

First, attend the pre-assessment appointment, sometimes by telephone. This is when the anesthesia team reviews your history and when any blood tests, an electrocardiogram or a chest assessment are ordered if needed (NHS).

Second, bring or send a complete medicines list. That includes prescription drugs, inhalers, eye drops, over-the-counter painkillers, and every herbal or dietary supplement. Some supplements affect bleeding or interact with anesthetic agents; the team will tell you which to continue and which to hold, and for how long.

Third, arrange practical support. Anesthesia and sedation impair judgment and reaction time for the rest of the day, so you will need an adult to take you home and, ideally, to stay with you overnight (Mayo Clinic). Do not plan to drive, sign legal documents or care for small children alone that evening.

Fourth, protect your general health. A cold, a urinary infection or a new rash near the treatment site can lead to postponement. Wash normally, avoid shaving the treatment area yourself unless instructed (razors create micro-cuts), and keep hydrated in the days before fasting begins.

People planning pelvic brachytherapy may also be started on a stool softener or a low-fiber diet a day or two ahead. Those who smoke are usually advised to stop, or at least to abstain on the day, because smoking increases airway irritation and slows tissue healing. None of this is glamorous. All of it reduces the chance that you arrive prepared only to be sent home.

Brachytherapy fasting instructions: why the empty stomach matters

Fasting before brachytherapy has nothing to do with the radiation. It exists because most applicator placements happen under general anesthesia, spinal anesthesia or deep sedation, and each of these relaxes the muscular valve at the top of the stomach and blunts the cough reflex. If the stomach is full, its contents can travel upward and be inhaled into the lungs, an event called aspiration that can cause serious pneumonia (NHS).

Typical guidance, which your own team will confirm in writing, follows a two-tier pattern. Solid food and milky drinks stop about six hours before the scheduled anesthesia time. Clear fluids, meaning water, black tea or coffee without milk, and diluted juice without pulp, may usually continue until about two hours before (NHS general anaesthesia guidance). Chewing gum and sweets count as food. So does a “light” snack.

The two-hour clear-fluid window is not a loophole; it is deliberate. Prolonged total fasting leaves people dehydrated, headachy and more prone to low blood pressure on the operating table, which is why modern anesthesia practice encourages sipping water up to the cutoff rather than fasting from the night before.

A few situations change the rules:

• Diabetes: fasting alters glucose control, so the pre-assessment team will give tailored advice about morning medicines and may schedule you first on the list.
• Reflux, hiatus hernia or a condition that slows stomach emptying: fasting times may be lengthened.
• Regular morning tablets: most can be taken with a small sip of water, but only as directed by the anesthesia team.

If you slip and eat or drink after the cutoff, tell the nurse honestly on arrival. The procedure may be delayed by a few hours rather than lost, and the team would far rather know than discover it under anesthesia.

Bowel prep before brachytherapy: what it involves and what it protects

Not every brachytherapy patient is asked to empty the bowel. Those treating the prostate, cervix, uterus, vagina or rectum usually are, and the reasons are mechanical rather than hygienic.

Take the prostate first. Seed or HDR needles are guided by an ultrasound probe resting in the rectum. Stool or gas between the probe and the gland scatters the sound waves, blurring the image the physician depends on for millimeter-accurate placement. An enema on the morning of the procedure, or the evening before, clears that window (MedlinePlus).

In gynecologic brachytherapy the concern is dose. The rectum and sigmoid colon sit directly behind the applicators, and radiation planning assumes those organs occupy a particular position. A rectum distended by stool or gas bulges forward into the high-dose region. Reducing rectal filling with a low-residue diet, a mild laxative or an enema helps keep the actual dose to the bowel close to the planned one. For treatments delivered over several sessions, some departments ask for a consistent bowel routine before each one so that anatomy looks the same each time.

What the preparation typically looks like, always as directed by your own team and never self-adjusted:

• A low-fiber, low-residue diet for one to two days: white rice, white bread, eggs, well-cooked skinless vegetables, and avoidance of beans, nuts, bran and raw salad that produce bulk and gas.
• A small-volume enema at a set time, usually the evening before or two to three hours before leaving home.
• Extra clear fluids until the fasting cutoff, because bowel prep dehydrates.

People with inflammatory bowel disease, a stoma, hemorrhoids that bleed, or a history of fainting with enemas should raise this at pre-assessment. The regimen can almost always be adapted; the goal is a quiet, empty rectum, not a particular product.

The anesthesia check: what the pre-assessment team wants to know

The anesthesia check is a structured conversation, sometimes with a short examination, that predicts how your body will respond to being made unconscious or numb and how it will recover. It usually happens days to weeks before the procedure, and it is the most common place where brachytherapy plans get quietly adjusted (Mayo Clinic).

Expect questions in roughly this order. Have you had anesthesia before, and were there problems such as severe nausea, slow waking or difficulty placing a breathing tube? Has any blood relative had a serious reaction to anesthesia? Do you have heart disease, high blood pressure, asthma or COPD, sleep apnea, kidney or liver disease, or diabetes? Do you smoke, drink alcohol regularly or use recreational substances? Are you allergic to any medicine, latex or adhesive dressings? What is your height and weight?

The medicines review is the heart of it. Blood thinners, whether prescription anticoagulants or aspirin-type antiplatelet drugs, raise bleeding risk along needle tracks and around applicators. Some are paused for a set number of days; some are bridged with an alternative; some are continued because stopping carries a greater stroke or clot risk. That decision belongs to the prescribing clinician in discussion with the anesthesia and oncology teams, and you should never stop a blood thinner on your own initiative. Diabetes medicines, some blood pressure tablets, certain antidepressants and herbal products such as ginkgo, garlic extract or St John’s wort also come up because of interactions or bleeding effects.

The team also looks at your airway (mouth opening, neck movement, loose teeth) and may listen to your heart and lungs. From this they assign a fitness grade and choose between general anesthesia, spinal anesthesia or sedation with local anesthetic. For many pelvic implants a spinal block, which numbs from the waist down while you remain drowsy but breathing on your own, is a common option; your anesthetist will explain which suits you and why.

Preparation by cancer site: a summary table

The three pillars of preparation apply differently depending on where the sources go. The table below summarizes what patients are commonly asked to do; it is a guide to the conversation, not a substitute for your own written instructions.

Treatment site	Fasting usually required?	Bowel preparation usually required?	Typical anesthesia	Other common steps
Prostate (LDR seeds or HDR)	Yes	Yes: enema before ultrasound-guided placement	General or spinal	Urine test to exclude infection; may go home with a temporary catheter
Cervix, uterus, vagina	Yes for applicator insertion	Often: low-residue diet and/or enema to reduce rectal filling	General, spinal or sedation	Bladder may be filled or emptied to a set volume for planning
Breast (after lumpectomy)	Sometimes, if sedation used for catheter placement	No	Local with or without sedation	Skin checks; wound must be healing
Skin (surface applicators)	No	No	None or local	Avoid creams on the area beforehand
Esophagus, lung (intraluminal)	Yes: endoscopy or bronchoscopy used	No	Sedation or general	Swallow or breathing assessment

Sources: Mayo Clinic, Cleveland Clinic and MedlinePlus patient guidance on brachytherapy procedures.

Two patterns stand out. Fasting tracks anesthesia, not radiation; where the sources can be placed with local anesthetic alone, food is usually allowed. Bowel prep tracks anatomy; it appears wherever the rectum either guides the imaging or sits in the line of fire. Knowing which column you are in explains most of what is on your instruction sheet, and any item that seems to contradict this table is worth a quick call to the department rather than a guess.

How painful is brachytherapy, honestly?

The placement of needles or applicators is the part that would hurt, and it is precisely the part done under anesthesia or a spinal block. Most people have no memory of it. The radiation itself is silent and painless; you cannot feel a source moving through a catheter any more than you feel an X-ray (Cleveland Clinic).

Discomfort tends to arrive in three places afterward. First, the entry sites. After prostate implants the skin between the scrotum and anus is bruised and tender for several days, and sitting on a firm chair can be uncomfortable; a soft cushion helps more than most people expect. Second, the organ itself. Swelling of the prostate can make urination sting and feel urgent for a few weeks, and some men are sent home with a catheter for a day or two while swelling settles (MedlinePlus). After gynecologic applicators, a cramping, period-like ache and light vaginal bleeding for a day or so are common.

Third, the waiting. When HDR applicators stay in place for hours or overnight between fractions, lying still with a pelvic device inserted is tiring and can ache in the lower back. Pain teams plan for this: patient-controlled analgesia, spinal or epidural infusions, and regular oral pain relief are standard tools, and you should ask for adjustment early rather than enduring it.

Pain scores in published patient series vary widely with site and technique, and no honest article can promise you a particular number. What the evidence and clinical experience agree on is that severe, escalating pain after brachytherapy is unusual and should be reported, because it can signal infection, urinary retention or a displaced applicator rather than expected soreness.

Do you need to stay in bed for brachytherapy?

It depends entirely on whether something is still inside you. The distinction between permanent seeds, temporary HDR sessions and multi-day implants explains almost all of the confusion around this question.

Permanent prostate seeds: no bed rest. You wake, pass urine, eat, and typically go home the same day or the next morning. Walking is encouraged. The seeds are anchored in tissue and do not shift with movement (MedlinePlus).

Outpatient HDR sessions: no bed rest between visits. Applicators go in, treatment lasts minutes, applicators come out, and you leave once the anesthesia has worn off. Some prostate and gynecologic programs deliver several fractions this way over one to two weeks; between them you live normally.

Applicators left in place for hours or days: yes, and strictly. When a cervical or uterine applicator is inserted once and used for several fractions over a day or two, or when a rod-and-catheter system remains for a course of pulsed treatment, you will be nursed flat or nearly flat, often with a urinary catheter, because sitting up or bending the hips could dislodge the device and change the dose geometry (Mayo Clinic). Nurses check position, manage pain and help with compression stockings or anticoagulant injections to reduce clot risk from immobility.

During those bed-bound hours the practical questions matter: how to eat lying down, what to do about boredom, and whether visitors can come. Radiation safety rules for HDR mean nothing radioactive is in the room between treatments, so visitors are usually fine once the source has retracted; the team will explain any restrictions that apply to your specific system. Ask about ankle exercises and breathing exercises in advance; small movements you can do safely make the long hours pass better and lower the risk of complications.

Radiation safety after treatment: what the precautions really mean

People are often more anxious about becoming radioactive than about the procedure itself. The honest picture is reassuring but not identical for everyone.

After HDR brachytherapy, whether one session or several, the source has been retracted into its shielded safe before you leave the treatment room. You are not radioactive. There are no restrictions on hugging, sharing a bed or holding a child (Cleveland Clinic).

After permanent LDR implants the seeds continue to emit low-energy radiation that is largely absorbed within the surrounding tissue, but a small amount reaches the skin surface. Departments therefore commonly advise, for a limited period that they will specify, avoiding prolonged close contact with young children and people who are pregnant, such as sitting a child on your lap for long stretches; brief hugs and being in the same room are generally not considered a problem (MedlinePlus). Sexual activity is usually permitted after a short interval, often with condom use for the first few ejaculations because a seed can occasionally pass in semen. Some men are asked to strain urine through a filter for a week or two for the same reason: a passed seed is rare, should be picked up with a spoon rather than fingers, placed in a container and returned to the department.

Two specific points catch people out. Airport security scanners can detect the faint emission from fresh implants, so patients are given a card describing the treatment. And cremation guidance exists because of the seeds’ long physical presence; families may be told about this, which can feel jarring but is routine record-keeping.

None of these measures suggests danger to you. They are conservative rules written for a population, and your team will state the timeframe that applies to the specific isotope you received.

What to expect after brachytherapy: the days and weeks that follow

The first 48 hours are about anesthesia recovery and local soreness. Drowsiness, a scratchy throat if a breathing tube was used, mild nausea and bruising at needle sites are typical and fade within a day or two (Mayo Clinic). Someone should be with you the first night.

From day two to roughly week two, the treated organ swells and then settles. Men often notice urinary frequency, urgency, a weak stream and burning; this usually peaks in the first weeks, and a smaller number experience it more persistently over the following months as the seeds deliver their dose (MedlinePlus). Women treated for cervical or endometrial cancer may have vaginal discharge, spotting, cramping and some bowel looseness. Fatigue is common across all sites, though generally milder than after a long external beam course (NHS radiotherapy side effects).

When people ask how long after brachytherapy they will feel better, the most honest answer is that acute effects generally improve over weeks, while late effects, which are less common, can appear months later. Vaginal dryness or narrowing, erectile changes, bowel urgency or occasional rectal bleeding are the recognized late risks in pelvic treatment; your team will discuss dilator use, pelvic floor advice or specialist referral where relevant. No timeline can be promised to an individual.

What not to do after brachytherapy is a shorter list than most expect:

• Do not lift heavy loads, cycle or do vigorous exercise for the period your team specifies, typically a week or two after pelvic implants, while tissue heals.
• Do not ignore an inability to pass urine; it is the most common reason for an urgent return visit.
• Do not take baths or swim until skin entry points have closed, if advised.
• Do not restart paused medicines, especially blood thinners, until the prescribing clinician confirms the timing.
• Do not stop drinking fluids because urination stings; dehydration concentrates urine and worsens it.

What people often get wrong about preparing for brachytherapy

Some myths cost people a canceled slot; others just cost them sleep. These are the ones clinicians hear most.

“Fasting from midnight is safest, so I’ll skip water too.” Arriving dehydrated makes cannulation harder and low blood pressure under anesthesia more likely. Clear fluids until the stated cutoff are recommended, not merely tolerated (NHS).

“An enema is just for cleanliness, so I can skip it if I’ve been to the toilet.” The enema clears the rectum for ultrasound clarity and dose accuracy. A normal bowel movement often leaves residual stool and gas; the imaging, not your comfort, decides whether it was enough.

“I’ll stop my blood thinner a week early to be safe.” Stopping anticoagulants without instruction exposes you to stroke or clot risk that may far outweigh procedural bleeding. Timing is a clinical decision made for you, with you.

“Brachytherapy is the same as a radioactive tablet.” Radioactive iodine capsules for thyroid disease are unsealed sources that circulate in body fluids and require different precautions. Brachytherapy sources are sealed; HDR leaves nothing behind and LDR seeds stay put in tissue (Cleveland Clinic).

“Because it’s internal, side effects are worse.” The opposite is usually true for tissue outside the target: the steep dose fall-off is the reason the technique exists. Side effects concentrate in the treated organ rather than spreading across the skin and abdomen (Mayo Clinic).

“I can drive myself home; it’s only a small procedure.” Any anesthesia or sedation rules out driving that day, and most units will not discharge you without a named adult escort.

“Supplements don’t count as medicines.” Several herbal products influence bleeding or anesthetic metabolism. Declare everything, including the fish oil and the turmeric capsules.

Questions to ask your care team before brachytherapy

A good pre-assessment appointment is a two-way conversation. Bring these written down; you will not remember them in the room.

• Which type am I having, HDR or LDR, and how many sessions? Will anything remain inside me afterward?
• What kind of anesthesia is planned, and why that choice for me? Who will be looking after my breathing and blood pressure?
• Exactly when do I stop solid food, and when do I stop clear fluids? Can I take my usual morning medicines with a sip of water?
• Do I need bowel preparation? If so, what, when, and what should I do if it does not work or makes me unwell?
• Which of my medicines and supplements should I pause, for how long, and who will tell me when to restart them?
• Will I have a urinary catheter, and for how long? Who removes it and what happens if I cannot pass urine at home?
• How long is the typical stay for this procedure, and does anyone need to stay with me overnight?
• What radiation precautions apply to me specifically, and for how long, around children, pregnant people and partners?
• What symptoms in the first week are expected, and which should make me phone the department or go to emergency care?
• What late side effects are recognized for this treatment site, roughly how common are they in published guidance, and what support exists if they occur?
• What are the alternatives for my situation, and what would you expect to be different about each?
• Who is my named contact, and what number do I call out of hours?

Notice that several of these questions ask for numbers and timeframes. It is reasonable to want them, and equally reasonable for the team to answer in ranges rather than promises, because published data describe groups, not the person sitting in the chair. Write the answers down, or ask whether a companion may attend to take notes; sedation-day instructions are easy to misremember (Mayo Clinic).

When to call your doctor after brachytherapy

Most recovery is uneventful. A small set of signs, however, should prompt a same-day call to the treatment team or, when severe, a visit to emergency care. Do not wait for a scheduled follow-up if any of these occur.

• Inability to pass urine, or passing only small dribbles with a painful, swelling lower abdomen. Urinary retention after prostate implants needs a catheter promptly (MedlinePlus).
• Fever above 38°C (100.4°F), shaking chills, or feeling suddenly unwell, which can indicate infection along needle tracks or in the urinary tract.
• Heavy bleeding: soaking a pad every hour vaginally, passing large clots, or persistent bright red rectal or urinary bleeding rather than light spotting.
• Severe or worsening pain not eased by the pain relief you were sent home with.
• A swollen, warm, painful calf, or sudden breathlessness and chest pain, which can signal a blood clot after a period of lying still.
• Persistent vomiting that prevents you keeping fluids down, or signs of dehydration such as dizziness and very dark urine.
• Redness, spreading warmth or pus at any skin entry point.
• Any applicator, catheter or seed that appears to have come out, or a seed you have passed; keep it in a container and inform the department.
• Confusion, extreme drowsiness or difficulty breathing in the hours after anesthesia.

Milder concerns, such as burning on urination, looser stools, light discharge or fatigue, are expected and can be raised at your routine review, but it is never wrong to phone the department’s advice line if you are unsure. Radiation oncology units keep such lines precisely because the early weeks raise questions that do not fit neatly into appointment slots (NHS).

Every judgment about restarting medicines, returning to work, resuming sexual activity or exercising rests with the team who placed the sources and know your imaging, your dose plan and your medical history. This article can explain the reasoning behind their instructions; it cannot replace them.

Frequently asked questions

How painful is brachytherapy?

The needle or applicator placement, which would hurt, is done under anesthesia or a spinal block, so most people have no memory of pain during the procedure. Afterward, expect bruising and tenderness at entry sites, urinary stinging after prostate implants, or period-like cramping after gynecologic applicators for days to a few weeks. The radiation itself is not felt. Severe or escalating pain is unusual and should be reported promptly.

What are typical brachytherapy fasting instructions?

Most units ask you to stop solid food and milky drinks about six hours before your anesthesia time and clear fluids such as water about two hours before, following NHS general anesthesia guidance. Chewing gum and sweets count as food. People with diabetes, reflux or slow stomach emptying may receive different timings, and regular morning medicines are usually taken with a small sip of water only if the anesthesia team has said so.

Why is bowel prep before brachytherapy needed?

Bowel prep is needed when the rectum affects placement or dose. In prostate implants an ultrasound probe in the rectum guides the needles, and stool or gas blurs the image. In cervical or uterine treatment a distended rectum bulges into the high-dose region, increasing bowel exposure. A low-residue diet, a mild laxative or a small enema, as directed by your team, keeps the rectum empty and the anatomy predictable.

What are the brachytherapy anesthesia risks?

The risks are those of anesthesia generally rather than anything specific to radiation: nausea, sore throat from a breathing tube, drowsiness, and rarely aspiration, allergic reaction or heart and breathing problems, which are more likely in people with existing heart or lung disease, sleep apnea or poorly controlled diabetes. The pre-assessment check exists to identify and manage these risks, and your anesthetist will explain the safest option for you.

What not to do after brachytherapy?

Avoid heavy lifting, cycling and vigorous exercise for the period your team specifies while tissue heals, and do not drive on the day of anesthesia. Do not restart paused medicines, especially blood thinners, without the prescriber’s confirmation. Do not ignore an inability to pass urine or a fever. After permanent seeds, follow the stated time-limited precautions around young children and pregnant people and use condoms initially if advised.

Do you need to stay in bed for brachytherapy?

Only if applicators remain in place between treatment fractions, as with some cervical or uterine regimens, when you are nursed flat for hours or a day or two to prevent the device moving. Permanent prostate seeds and outpatient HDR sessions require no bed rest; you can walk the same day once anesthesia has worn off. Ask about ankle and breathing exercises if bed rest is planned, to reduce clot and chest risks.

How long after brachytherapy will I feel better?

Anesthesia effects and local soreness typically fade within a day or two, while urinary, bowel or vaginal symptoms from organ swelling usually peak in the first few weeks and then improve over weeks to months as tissue settles. Fatigue is common but generally milder than after long external beam courses. Late effects can appear months later in a minority of people. Your team can give ranges for your treatment site, not promises.

Am I radioactive after brachytherapy and can I be around children?

After HDR treatment you are not radioactive because the source is withdrawn before you leave the room. After permanent LDR seeds a small amount of low-energy radiation reaches the skin surface, so teams commonly advise avoiding prolonged close contact with young children and pregnant people, such as long periods on your lap, for a limited time they will specify. Brief hugs and being in the same room are generally not restricted.

What happens at the pre-anesthesia assessment before brachytherapy?

A nurse or anesthetist reviews your medical history, previous anesthetics and any family reactions, allergies, smoking and alcohol use, and every medicine and supplement you take. They may examine your airway, heart and lungs, and order blood tests or an electrocardiogram if needed. From this they choose between general, spinal or sedation anesthesia, decide which medicines to pause, and give your written fasting and bowel preparation instructions.

What to expect after brachytherapy in the first 48 hours?

Expect drowsiness, possible mild nausea, a scratchy throat if a breathing tube was used, and bruising or tenderness where needles or applicators entered. Men may have a temporary urinary catheter and burning when it is removed; women may have light bleeding and cramping. An adult should stay with you overnight, you should not drive, and you should phone the department if you cannot pass urine, develop a fever or bleed heavily.
