7.4 Pre-operative, Post-operative & Postmortem Care

Pre-operative, Post-operative & Postmortem Care

The surgical continuum demands meticulous clinical coordination across three distinct phases: the pre-operative phase (preparation and risk mitigation prior to surgery), the intra-operative phase (surgical intervention in the operating room), and the post-operative phase (recovery and prevention of systemic complications). Patient Care Technicians play a vital role during pre-op preparation and post-op floor recovery, where attentive monitoring directly prevents surgical site infections (SSIs), respiratory failure, and venous thromboembolism.

Similarly, when a patient reaches the end of life, providing dignified, respectful, and legally compliant postmortem care represents one of the most profound duties in patient care. Mastering the clinical protocols of perioperative maintenance and postmortem preservation ensures optimal patient safety and maintains legal compliance.

1. Pre-operative Preparation & Safety Protocols

Thorough pre-operative preparation mitigates anesthesia risks, reduces the surgical bioburden, and establishes baseline physiologic parameters.

Verification of NPO Status

• Definition: Nil per os (NPO) translates to "nothing by mouth." Elective surgical patients are placed on NPO status according to the anesthesia order. Many orders still read "NPO after midnight," but American Society of Anesthesiologists (ASA) fasting guidance for healthy patients allows clear liquids until 2 hours before elective anesthesia and requires 6 hours after a light meal and 8 hours after fried or fatty food; always follow the specific order.
• Physiological Rationale: General anesthesia abolishes the patient's protective laryngeal reflexes (gag and cough reflexes) while relaxing the lower esophageal sphincter. If food or liquid remains in the stomach, the patient risks regurgitating acidic gastric contents into the pharynx and aspirating them into the tracheobronchial tree. Pulmonary aspiration under anesthesia causes chemical pneumonitis (Mendelson's syndrome), severe bronchospasm, hypoxemia, acute respiratory distress syndrome (ARDS), and high mortality.
• PCT Responsibilities:
  • Remove all water pitchers, drinking glasses, food trays, and snack bowls from the patient's bedside table and room.
  • Place a prominent "NPO - Nothing by Mouth" sign over the bed.
  • Directly question the patient and family regarding any oral intake: "Have you had anything to eat, drink, chew, or sip since midnight—including water, coffee, chewing gum, hard candy, or ice chips?"
  • Immediate Reporting: If the patient consumed ANY solid or liquid, report this immediately to the registered nurse and surgical team. Surgery may need to be postponed or cancelled to permit gastric emptying.

Surgical Skin Preparation & Hair Removal

• Antiseptic Cleansing: Patients are instructed to shower or receive bed baths using Chlorhexidine Gluconate (CHG) antiseptic wash or pre-packaged 2% CHG cloth wipes the evening before and morning of surgery. CHG binds to the stratum corneum, providing sustained antimicrobial action that reduces cutaneous flora (Staphylococcus aureus).
• The Absolute Razor Prohibition: Shaving the surgical site with a safety razor is STRICTLY PROHIBITED. Razors scrape the skin and cause microscopic epidermal cuts, nicks, and abrasions. Within hours, cutaneous bacteria colonize these micro-abrasions, dramatically increasing the incidence of Surgical Site Infections (SSIs).
• Approved Method: If hair removal is specifically ordered by the surgeon, it must be performed immediately prior to surgery using electric surgical clippers with single-use disposable clipping heads, or chemical depilatory creams. Clipping cuts hair close to the skin surface without violating epidermal integrity.

Pre-operative Checklist Execution

• Dentures and Partials: Must be removed prior to transport to the OR. Loose dental prostheses can be dislodged during endotracheal intubation, causing airway obstruction or dental fracture. Place dentures in a labeled denture cup filled with cool water and secure them per facility policy.
• Foreign Objects: Remove all eyeglasses, contact lenses, hearing aids, wigs, hairpins, and hairpieces. (Hairpins conduct electrical current during surgical electrocautery, causing scalp burns).
• Jewelry and Piercings: All rings, watches, bracelets, necklaces, and body piercings must be removed. Metal conducts electrosurgical grounding currents, risking severe contact burns. Additionally, intraoperative fluid shifts cause tissue edema; rings left on fingers can cause digital ischemia and necrosis. If a plain wedding band cannot be removed, it must be taped securely to the finger with adhesive tape per hospital policy.
• Nail Polish and Cosmetics: Nail polish (especially dark shades) and artificial acrylic nails must be removed from at least one or two fingers. They impede pulse oximeter light transmission and prevent direct visual assessment of capillary refill and nail bed perfusion.
• Pre-Sedative Voiding: Have the patient void completely immediately prior to the administration of pre-operative sedative medications (such as midazolam or opioids). Pre-op sedatives cause drowsiness, muscle weakness, and ataxia, creating an extreme fall hazard if the patient attempts to ambulate afterward. Furthermore, emptying the bladder reduces the risk of accidental surgical bladder puncture during lower abdominal or pelvic procedures.
• Valuables and Belongings: Inventory all clothing, luggage, money, and jewelry on a hospital personal property form. Co-sign the inventory with the patient or family, and lock valuables in the hospital safe.

2. Post-operative Monitoring & Initial Floor Care

When a patient arrives on the surgical floor from the Post-Anesthesia Care Unit (PACU), the technician must assist the nurse with an immediate, structured intake assessment.

PACU Handoff & Airway Assessment

• Airway & Breathing: Verify airway patency first. Observe rate, depth, and effort of respirations. Stridor or snoring respirations indicate upper airway obstruction by the tongue or laryngeal edema; notify the nurse immediately.
• Post-Op Vital Signs Protocol: Anesthesia drugs, blood loss, and fluid shifts create hemodynamic instability. Post-operative vital signs must be recorded according to a strict schedule:
  • Every 15 minutes for the 1st hour (4 sets).
  • Every 30 minutes for the 2nd hour (2 sets).
  • Every 1 hour for the next 4 hours.
  • Every 4 hours thereafter (or per institutional surgical protocol).
  • Alerts: Report systolic BP < 90 mmHg, heart rate > 100 or < 60 bpm, respiratory rate < 10 or > 20 breaths/min, temperature > 100.4°F (38.0°C), or SpO2 < 92% immediately.

Surgical Dressing Protocols (The Primary Dressing Rule)

• The Golden Rule: The Patient Care Technician (and floor nurse) must NEVER remove or change the primary surgical dressing applied in the operating room. The initial surgical dressing is removed exclusively by the attending surgeon, usually 24 to 48 hours post-op, to inspect the pristine incision.
• Managing Drainage: Inspect the surgical dressing during every vital signs encounter.
  • If drainage or blood is observed on the exterior of the dressing, use a surgical pen or marker to trace the exact outline/perimeter of the drainage stain directly on the bandage.
  • Record the date and exact military time adjacent to the line.
  • If the dressing becomes saturated (blood soaking through), do not remove it. Reinforce the dressing by placing sterile gauze pads directly over the existing dressing and taping them securely.
  • Notify the registered nurse immediately so the nurse can evaluate for active surgical hemorrhage.

3. Prevention of Postoperative Complications

Postoperative immobility, pain, and anesthesia-induced respiratory depression place surgical patients at immense risk for pulmonary and vascular complications.

Pulmonary Complications: Atelectasis & Hypostatic Pneumonia

Under general anesthesia, diaphragmatic movement is depressed, and normal surfactant production decreases. Postoperative incision pain causes patients to breathe shallowly. Consequently, the small alveoli in the dependent lung bases collapse—a condition known as atelectasis.

• If atelectasis persists, trapped bronchial secretions pool in the collapsed alveoli, fostering rapid bacterial growth and progressing to hypostatic pneumonia.
• Incentive Spirometry (IS): The single most effective mechanical intervention to reverse atelectasis.
  • Technique: Assist the patient into a high Fowler's or semi-Fowler's position. Instruct the patient to exhale normally, place the mouthpiece tightly between the lips to create a complete seal, and inhale SLOWLY and DEEPLY through the mouth (as if sucking through a straw).
  • The slow inhalation lifts the flow indicator/piston toward the target volume marker.
  • Instruct the patient to hold their breath for 3 to 5 seconds at peak inhalation before removing the mouthpiece and exhaling gently.
  • Instruct the patient to perform this maneuver 10 times every waking hour.
• Controlled Diaphragmatic Deep Breathing and Coughing: Follow incentive spirometry with 2 to 3 deep diaphragmatic breaths and a forceful cough to clear mobilized secretions.
• Incision Splinting: Coughing exerts intense intra-abdominal and intrathoracic pressure, causing agonizing incision pain and risking wound dehiscence (surgical wound separation). Teach the patient to splint the incision by pressing a firm pillow or folded blanket firmly against the surgical incision while coughing or turning. Splinting supports suture lines and dramatically alleviates pain.

Cardiovascular Complications: Venous Thromboembolism (DVT / PE)

Surgical anesthesia causes systemic vasodilation, while postoperative bed rest causes venous stasis in the lower extremities (part of Virchow's Triad). Blood pools in the deep calf veins, forming a Deep Vein Thrombosis (DVT). If a thrombus dislodges, it travels through the vena cava into the pulmonary arterial bed, causing a catastrophic Pulmonary Embolism (PE).

• Sequential Compression Devices (SCDs): Inflatable plastic or fabric sleeves wrapped around the patient's calves (or calves and thighs) connected to an electric pneumatic compressor pump. The pump sequentially inflates and deflates air bladders from ankle to knee (typically at 35–45 mmHg), mimicking the pumping action of calf muscles during walking, accelerating venous blood return, and preventing stasis. SCDs must be worn continuously whenever the patient is in bed or sitting in a chair; remove only during ambulation or hygiene.
• Anti-Embolism Stockings (TED Hose): Elastic, graduated compression stockings that exert firm pressure at the ankle (roughly 18 mmHg) that gradually decreases up the leg.
  • Fitting: Must be measured precisely using a tape measure around calf/thigh circumference and leg length. Stockings that are too small exert a tourniquet effect that impedes arterial flow; stockings that are too loose offer zero compression.
  • Maintenance: Ensure stockings are completely smooth with no wrinkles, folds, or rolled tops (wrinkles concentrate pressure, causing localized skin necrosis). Remove at least once per shift (every 8 to 12 hours) for skin inspection and hygiene, then reapply.
• Arteriovenous Impulse (AVI) Foot Pumps: Foot-cover devices that rapidly compress the plantar venous plexus to push blood upward; apply per order, keep them on while in bed, check the skin under the cover, and report pain or redness.
• Early Ambulation: The most physiological and effective prophylactic intervention. Assist the patient out of bed as soon as ordered by the surgical team.

4. Postmortem Care: Dignity, Technique & Legal Protocols

Postmortem care encompasses the physical and psychosocial care delivered to a deceased patient's body and family immediately following death.

Legal Prerequisite: Medical Pronouncement

• The Absolute Rule: Postmortem care must NEVER begin until death has been officially confirmed and formally pronounced by a licensed physician or registered nurse in accordance with state laws and hospital policy. The exact time of death and the examining clinician's documentation must be recorded in the medical chart.

Infection Control & Cultural Reverence

• Infection Control: Maintain Standard Precautions during all postmortem procedures. Microorganisms do not die when the patient dies; wear examination gloves, a protective gown, and eye protection if fluid splash is possible.
• Dignity and Cultural Customs: Treat the body with profound respect and gentle handling at all times. Before beginning, determine whether the patient's family, culture, or religion requires specific rituals (e.g., Orthodox Judaism requires that the body not be left alone and handled only by designated Jewish burial societies; Islamic tradition requires that the body be positioned facing Mecca and washed by individuals of the same gender; Roman Catholic families may request a priest to pray with them (the Anointing of the Sick is ideally given before death)).

Step-by-Step Body Preparation Protocol

1. Positioning (The 30-Degree Rule): Place the body in a normal anatomical supine position with the head of the bed elevated 30 degrees immediately.
   • Rationale: Elevating the head prevents venous blood from pooling gravitationally in the head, face, and neck. Blood pooling causes permanent, dark reddish-blue discoloration (livor mortis / postmortem hypostasis) and facial congestion, which is deeply distressing to viewing family members.
2. Closing the Eyes: Close the patient's eyelids gently by pulling down on the eyelashes. If the eyes do not stay closed, place a moist cotton ball over the closed lids for a few minutes to hold them in place.
3. Managing Dentures and the Mouth: If the patient wore dentures, insert them into the mouth immediately before rigor mortis (stiffening of skeletal muscles, occurring 2 to 4 hours postmortem) sets in, unless facility policy dictates otherwise. Dentures preserve normal anatomical facial contours. Close the mouth gently; if necessary, place a small, rolled washcloth beneath the chin to keep the jaw closed.
4. Hygiene and Cleanliness: Bathe any areas of the body soiled with blood, emesis, urine, or feces. Comb and neatly arrange the patient's hair. Replace soiled bed linens with fresh, clean linens.
5. Dressings and Drainage: Replace soiled surgical dressings with clean, dry gauze dressings secured neatly with paper tape. Place an absorbent incontinence pad beneath the buttocks to capture any fluid or stool leakage caused by postmortem relaxation of internal and external sphincters.
6. Family Viewing Environment: Straighten the arms alongside the body with palms down. Cover the body up to the chest/shoulders with a clean top sheet, leaving the head, face, and hands exposed. Remove all clutter, medical trash, and biohazard bins from the room. Dim the lighting and provide comfortable seating for grieving family members.

5. Medical Examiner & Autopsy Cases: Strict Preservation Mandate

When a patient's death falls under the legal jurisdiction of the Medical Examiner (ME) or Coroner, clinical protocols change dramatically.

Criteria for Medical Examiner / Autopsy Cases

State laws commonly require reporting a death to the coroner or medical examiner in circumstances like these (the exact criteria vary by state). The medical examiner or coroner then decides whether to accept the case and whether to perform an autopsy:

• Death occurring within 24 hours of hospital admission.
• Death occurring during or immediately following a surgical procedure or anesthesia.
• Unexpected, unexplained, sudden, or violent deaths (trauma, motor vehicle collisions, falls).
• Suspected homicides, suicides, drug overdoses, poisonings, or workplace fatalities.
• Incarcerated individuals or deaths in psychiatric custody.
• Deaths in which the attending physician cannot certify a natural cause. (A hospital autopsy requested by the physician or family is a separate, consent-based process.)

The Mandatory Preservation Rule

• Strict Directives:
  • DO NOT REMOVE peripheral IV catheters, central venous access lines, arterial lines, or PICC lines.
  • DO NOT REMOVE endotracheal tubes, tracheostomy tubes, or oral airways.
  • DO NOT REMOVE indwelling Foley catheters, rectal tubes, or nasogastric (NG) tubes.
  • DO NOT REMOVE chest tubes, Jackson-Pratt drains, or surgical drains.
  • DO NOT CUT any tubes or lines. Cutting lines destroys physical evidence regarding tube depth and anatomical placement.
  • Action: Clamp or cap open tubes to prevent leakage, coil the lines neatly, and tape them securely to the patient's body.
• Legal Rationale: Removing, altering, or cutting invasive lines destroys critical forensic and legal evidence regarding proper anatomical tube placement, medical interventions, and potential contributory causes of death.

6. Identification Tags & Belongings Inventory

Accurate postmortem identification ensures proper chain of custody between the hospital, morgue, and funeral home.

The Standard Three-Tag Protocol

Most healthcare facilities mandate attaching three identical identification tags:

1. Tag 1 (The Body): Attached directly to the patient's great right toe (or right wrist if the toe is unavailable).
2. Tag 2 (The Shroud): Attached to the exterior zipper pull or outside surface of the shroud or zippered body bag.
3. Tag 3 (The Personal Belongings): Attached to the patient's personal property / belongings bag.

Wristband Rule: The patient's original hospital identification wristband must NEVER be removed; it must remain intact on the patient's wrist throughout morgue transfer.

Personal Belongings & Valuables Inventory

• Carefully collect all personal clothing, eyeglasses, jewelry, electronics, and valuables.
• Document every single item on a hospital personal belongings inventory sheet using objective, descriptive terminology:
  • Document "yellow metal band with clear white stones" rather than "gold diamond ring."
  • Document "silver-colored watch" rather than "silver Rolex."
• Have the inventory co-signed by another clinical staff member as a witness, or co-signed by the family member receiving the belongings.

7. Clinical Scenarios & Practice Traps

Bedside Scenario: The Saturated Laparotomy Dressing

A technician is obtaining routine vital signs on a patient who returned from an exploratory laparotomy three hours ago. The technician notices that the primary abdominal surgical dressing is completely saturated with bright red blood across a 6-centimeter circle.

• Clinical Trap: Peeling off the dressing to see if the staples are holding, or irrigating the wound.
• Pathology: The primary surgical dressing applied in the OR protects pristine suture lines and stabilizes the initial fibrin clot. Removing the dressing tears away clotting factors, triggers massive hemorrhage, and introduces hospital pathogens.
• Correct Action: Do not remove the dressing. Immediately outline the border of the blood with a surgical marker, note the date and time, place sterile gauze pads directly over the dressing to reinforce it, and notify the registered nurse immediately to evaluate for surgical hemorrhage.

Bedside Scenario: Removing Lines on an ME Case

A 42-year-old trauma patient dies in the intensive care unit 12 hours after admission following a fall from scaffolding. The physician informs the staff that the coroner has accepted the case for a mandatory forensic autopsy. The technician prepares to bathe the body and begins pulling out the endotracheal tube and peripheral IVs.

• Clinical Trap: Removing invasive lines and tubes before transfer to the morgue.
• Pathology: In a forensic death, the position of endotracheal tubes, IV catheters, and drains represents physical legal evidence. Pulling lines alters the anatomical crime/injury scene and violates state medical examiner statutes, subjecting the worker and facility to legal sanctions.
• Correct Action: Leave all tubes, IVs, catheters, and drains completely intact. Do not cut or pull anything. Coil and clamp tubes securely to prevent fluid leakage, wash non-invasive body surfaces, attach the toe tag and shroud tag, and transfer the body to the morgue.
