Patient Safety: Special Populations, Transfer and Positioning

This is Unit Fifteen of Tech in Surgery Prep. Unit Fourteen ended with a field rebuilt because nobody had watched it. This unit turns from the field to the patient: identifying, moving and positioning a person who cannot protect themselves. Carry one idea through this lecture. An anesthetized patient cannot report pain from a pinched nerve or a pressure point, so the team must notice for them, and anyone who sees a problem says so. A worked example near the end shows the scrub person's view catching one the others missed. By the end you will be able to explain identification, fasting and safe transfer. To apply the principles of positioning and name the main positions. To prevent pressure and nerve injuries and plan for special populations. And to meet communication needs, keep the patient warm, and check the skin.

Five entries on safety before and during the move onto the table.

Safety starts earlier.

TSC 351 Safety Begins Before the Room

Patient safety begins with the preoperative assessment, long before the operating room. Nurses gather the history, allergies, medications and risks so the team can plan for each patient. The scrub person reads what the team learned, such as allergies and special needs, before setting up.

The right patient, again and again.

TSC 352 Identifying the Patient

The right patient is confirmed repeatedly, with at least the full name and date of birth. Identity is checked in the preoperative area against the band and record, again on arrival in the operating room before anesthesia, and at the time out, when the whole team confirms identity, procedure and site, reading the procedure from the consent. At the end, specimen labels are read aloud with the patient's name. Wrong-patient and wrong-site surgery are preventable, and the repeated checks exist because any one check can fail.

Nothing by mouth.

TSC 353 NPO and Why It Matters

Patients are usually told to take nothing by mouth, called NPO, before surgery. An empty stomach reduces the risk of vomiting and aspiration, inhaling stomach contents, under anesthesia. In an emergency the patient may not have fasted, and anesthesia plans for that higher risk.

A moment of risk.

TSC 354 Transferring the Patient

Moving a patient onto and off the table is a risk for patient and staff. Make sure enough staff are present. The anesthesia provider manages the airway throughout. Use a lateral transfer device or powered lift rather than lifting by hand. Move together on one agreed count. Once on the table, secure the patient so they cannot fall, and protect lines and tubes. Falls from the table are a recognized complication, so nobody lets go until the patient is secured.

Keeping the patient on the table.

TSC 355 Preventing Falls

Falls are prevented by secure positioning, safety straps and careful handling. Poor securing or an unstable patient can lead to a fall, so the strap goes on as soon as the patient is on the table. Never leave an unsecured patient on the table, even for a moment.

Seven entries on the principles of positioning and the positions surgery uses most.

Access and protection together.

TSC 356 Principles of Positioning

Positioning gives the surgeon access while protecting the body. It is a team effort, planned for the procedure, anatomy and conditions. The position exposes the site and keeps the body aligned. Bony prominences are padded and pressure spread. Nerves are protected from stretch and compression. Breathing and circulation stay free, and anesthesia can reach the airway. In long cases, position and padding are rechecked and documented. An anesthetized patient cannot report pain, so more than one person checks.

On the back.

TSC 357 Supine

In supine, the patient lies on their back with arms tucked or on armboards. It is the most common position, used for many abdominal, chest and cardiac procedures. Armboards are adjusted for height and angle so circulation is not compromised.

Face down.

TSC 358 Prone

In prone, the patient lies face down, often with chest and pelvic supports. It is used for spinal surgery and the back of the head. The face, eyes and chest need careful padding and checks, because pressure there can injure.

On one side.

TSC 359 Lateral and Kidney

In the lateral position, the patient lies on one side, operative side up or down as the surgery needs. It serves some hip, kidney and chest procedures; kidney position is a modified lateral with the table split. Supports prevent rolling, and the lower arm and leg are padded.

Legs in stirrups.

TSC 360 Lithotomy

In lithotomy, the patient lies on their back with legs raised in stirrups attached to the end of the table. It is used for gynecologic and urologic procedures. Stirrups are adjusted to give this patient the right elevation and spread, and padded to protect the legs.

Tilting the table.

TSC 361 Trendelenburg and Reverse

Trendelenburg tilts the supine patient head down; reverse Trendelenburg tilts the head up. The first improves the view in pelvic and lower abdominal surgery; the second serves upper abdominal and some neurosurgical procedures. Tilting shifts the patient's weight, so they are secured against sliding.

Head raised.

TSC 362 Fowler's and Sitting

In Fowler's position, the patient lies on their back with the head of the table raised, for some cranial, eye and neck procedures. A sitting position, leaning forward, is used to place epidural anesthesia. In every position, the anesthesia provider watches vital signs closely.

Six entries on positioning injuries, and on children, older adults, pregnancy and obesity.

Five positioning complications.

TSC 363 Pressure Points and Padding

Pressure injuries form where prolonged pressure falls on bony areas such as heels and elbows, and padding and repositioning prevent them. Nerve injuries come from compression or stretching, prevented by padding and avoiding extreme positions. Compartment syndrome, when pressure cuts off a muscle's blood flow, is prevented by limb alignment. Eye injuries are prevented by eye protection, and muscle and joint strain by careful handling. Long procedures raise every risk, so skin and padding are checked when possible, and concerns told to the team at once.

Nerves at risk.

TSC 364 Nerve Injuries From Position

Nerves can be injured by compression or stretching, causing numbness, weakness or even paralysis. Common sites include the arms, legs and head, so arms are not overextended on armboards and limbs are padded where nerves lie near the surface. These injuries may not show until the patient wakes, so prevention is the only protection.

Children are different.

TSC 365 Pediatric Patients

Infants and young children differ from adults physically and emotionally. They clear medications more slowly, so medications are dosed by weight. They lose heat easily, so temperature is watched and warming used. Their airways are smaller and more pliable. They may be frightened, and a child's report of awareness during anesthesia is taken seriously. Parents or guardians consent and are kept informed. Everything is sized for the child, and the scrub person checks that pediatric sizes are on the field before the case.

Older adults.

TSC 366 Older Adults

Older adults are more vulnerable because of age-related changes and multiple conditions. The textbooks note reduced heart and lung reserve, slower drug metabolism, more medications, fragile skin, temperature sensitivity, and a higher risk of delirium after surgery. Gentle handling, careful padding and warming matter even more.

Two patients.

TSC 367 Pregnant Patients

Surgery during pregnancy involves two patients, the pregnant patient and the fetus. Pregnancy changes the heart, lungs and digestion, anesthesia can affect the fetus, and regional anesthesia is often preferred. A pregnancy test is often part of testing for patients who could be pregnant, because it changes the plan.

Planning for size.

TSC 368 Patients With Obesity

Patients with obesity need special planning for positioning, transfer and anesthesia. Moving them takes significant force, so powered lifts, lateral transfer devices and extra staff are used, and some anesthesia risks may rise. Tables, armboards and positioning devices must be rated for the patient's size.

Six entries on communication, warmth, latex and skin, then two worked examples. The opening idea is paid off at the first.

Understanding is safety.

TSC 369 Guardians, Interpreters and Communication Needs

Some patients need a guardian, an interpreter or other support to understand and take part in their care. Patients with cognitive or developmental impairment need a guardian present, who may give consent. Patients whose preferred language differs need a professional interpreter, and the textbook warns never to assume a language from appearance or name. Sensory or cognitive deficits may need simpler instructions and more time, and families are often important partners. A patient who did not understand may not report a symptom or a risk, so these needs are met before the room.

Keeping the core warm.

TSC 370 Hypothermia Prevention

Hypothermia, a core temperature below about thirty-six degrees Celsius, can harm patients and slow healing. Causes include a cold room, open cavities, anesthesia and cool fluids; prevention uses insulation and active warming, with warmed fluids. It can disturb heart rhythm and raise infection risk, so warming starts early.

A room without latex.

TSC 371 Latex-Safe Rooms

Patients with latex allergy need a room and supplies free of latex. Many departments keep a latex-free cart, and many have removed latex products altogether to protect patients with undiagnosed allergies. A latex allergy noted at the time out changes what the scrub person may open.

Skin, before and after.

TSC 372 Skin Before and After

The skin is assessed before positioning and again at the end, and changes are documented. The team looks for redness, pressure marks and discoloration, especially over bony areas and under devices. A mark found at the end is reported to the recovery nurse so it can be followed.

Turning a patient prone.

TSC 373 Positioning a Prone Spine Case

A worked example, constructed for this course, pays off the opening idea. An adult is identified, anesthetized on the stretcher, and the breathing tube secured. Five people turn the patient onto chest and hip supports on one count, with anesthesia controlling the head and airway. The face rests on a padded headrest with no pressure on the eyes; the chest and hips sit on the supports so the abdomen hangs free; the arms rest bent on padded boards; knees and toes are padded. From the back table, the scrub person sees a breast compressed under a chest support, and the team adjusts it. Two hours in, anesthesia rechecks the face and eyes. Anyone who sees a problem says so.

A frightened child.

TSC 374 A Child and a Parent at the Door

A worked example, constructed for this course, follows a four-year-old having tonsils removed. The parent, the legal guardian, has consented, and the nurse confirms the child's identity with the parent and the band, using a professional interpreter for the parent's preferred language. The room is warmed in advance, with a warming device on the table. Marisol, the scrub person, has set out pediatric instruments and suction, and confirms the medications are labelled with their strengths, because children are dosed by weight. Anesthesia has a child-sized airway ready. The child falls asleep with the parent nearby, as policy allows. Preparation done before the child arrived let the team focus on the child.

Look at what you can now do. You can explain why safety starts before the room, how identity is confirmed again and again, why patients fast, and how to transfer and secure a patient. You can apply the principles of positioning and describe supine, prone, lateral, lithotomy, the Trendelenburg tilts and Fowler's. You can prevent pressure and nerve injuries, and plan for children, older adults, pregnant patients and patients with obesity. And you can meet communication needs, prevent hypothermia and latex reactions, and check the skin before and after. Unit Sixteen turns to the safety equipment and the surgical time out.
