Perioperative Phase 1
1. Preoperative Nursing Care & Informed Consent Standards
The preoperative phase extends from the initial decision for surgical intervention until the client is physically transferred to the operating room suite. Preoperative nursing prioritizes baseline physiological assessment, risk factor identification, client education, and legal consent validation.
Informed Consent Legal Responsibilities
Informed consent protects client autonomy and ensures legal authorization for invasive procedures.
- Provider's Role: The surgeon is legally obligated to explain the procedure, surgical necessity, risks, benefits, potential complications, and reasonable therapeutic alternatives.
- Nurse's Role: The nurse witnesses the signature, confirming that the client is competent, voluntary, authentic, and alert.
- Rule of Clarification: If the client expresses misunderstanding, doubt, or lack of knowledge regarding the surgical procedure, the nurse must not attempt to explain the operation; the nurse must contact the surgeon to return and explain the procedure before the client signs or receives pre-anesthetic sedatives.
Preoperative Assessment Checklist
Systematic screening eliminates intraoperative anesthetic and surgical hazards.
- NPO Status: Minimum 6 to 8 hours for solid food and 2 hours for clear liquids to prevent pulmonary aspiration during general anesthesia induction.
- Allergy Screening: Assess for Latex Allergy cross-reactivity (associated with allergies to bananas, kiwis, avocados, chestnuts, and papayas).
- Medication Review: Identify anticoagulants (hold aspirin/warfarin 5–7 days pre-op), NSAIDs, antihypertensives, and antidiabetics (hold Metformin 48 hrs if contrast used; adjust morning insulin per protocol).
- Pre-op Teaching: Teach incentive spirometry, diaphragmatic breathing, controlled coughing (with wound splinting), and early ambulation *before* surgery.
Perioperative Phase 2
2. Intraoperative Safety & The WHO Surgical "Time-Out"
The intraoperative phase begins when the client enters the surgical suite and terminates upon transfer to the Post-Anesthesia Care Unit (PACU). Intraoperative nursing emphasizes strict aseptic technique, safe client positioning, electrical/thermal grounding, instrument counting, and error prevention protocols.
WHO Surgical Safety Checklist & Universal "Time-Out" Protocol
To eliminate wrong-site, wrong-procedure, and wrong-person surgical sentinel events, a mandatory pause occurs immediately before the surgical incision is made.
- Active Participants: Entire surgical team (circulating nurse, scrub nurse/tech, surgeon, and anesthesia provider).
- Mandatory Verification Elements:
- Correct client identity confirmed using two identifiers.
- Correct surgical procedure verbally verified.
- Correct surgical site and anatomical side confirmed (site marked by operating surgeon pre-op).
- Correct client positioning verified.
- Availability of necessary implants, special equipment, and radiologic images.
- Confirmation of prophylactic antibiotic administration (within 60 minutes prior to incision).
Anesthetic Intraoperative Emergency
3. Malignant Hyperthermia (MH): Pathophysiology & Crisis Protocol
Malignant Hyperthermia (MH) is a rare, life-threatening autosomal dominant pharmacogenetic disorder of skeletal muscle calcium regulation. It is triggered by volatile halogenated inhaled anesthetics (e.g., Isoflurane, Sevoflurane, Desflurane) and depolarizing neuromuscular blockers (e.g., Succinylcholine).
Clinical Manifestations
- Earliest & Most Sensitive Sign: Unexplained rapid surge in End-Tidal Carbon Dioxide ($\text{EtCO}_2$) combined with hypercapnia and severe sinus tachycardia.
- Musculoskeletal: Masseter muscle rigidity (jaw spasm) and generalized muscle rigidity ("board-like" body).
- Metabolic: Severe mixed respiratory and metabolic acidosis, hyperkalemia, and myoglobinuria (dark brown urine secondary to rhabdomyolysis).
- Late Sign: Extreme, rapid elevation in body temperature (rising $1\text{--}2^\circ\text{C}$ every 5 minutes, potentially reaching $> 105^\circ\text{F}$ [$40.5^\circ\text{C}$]).
Emergency Crisis Protocol
- 1. Immediately Stop Anesthesia: Discontinue volatile anesthetic agents and succinylcholine. Notify the surgeon to halt surgery.
- 2. Hyperventilate: Administer $100\%$ high-flow oxygen using a clean, non-rebreather circuit or charcoal filters.
- 3. Administer Antidote: Give IV Dantrolene Sodium rapidly ($2.5\text{ mg/kg}$ IV push). Dantrolene acts directly on skeletal muscle by inhibiting calcium release from the sarcoplasmic reticulum.
- 4. Active Core Cooling: Administer iced IV 0.9% Normal Saline, perform gastric lavage with cold saline, and apply cooling blankets/ice packs to groin, axillae, and neck. Stop cooling when body temp reaches $38^\circ\text{C}$ ($100.4^\circ\text{F}$) to avoid hypothermia.
- 5. Manage Complications: Treat hyperkalemia (IV insulin and dextrose) and acidosis (IV sodium bicarbonate).
Perioperative Phase 3
4. Postoperative PACU Recovery & Atelectasis Prevention
The postoperative phase begins with admission to the PACU and continues through wound healing and complete recovery.
1. PACU Airway & Hemodynamic Assessment Priority
• Airway (Patent Airway): Unconscious or semi-conscious post-op clients are at high risk for tongue obstruction. Position client in the side-lying (lateral recumbent) recovery position until airway reflexes return.
• Breathing & Circulation: Assess respiratory rate, depth, and oxygen saturation. Monitor vital signs every 15 minutes. Report a blood pressure change of $\ge 25\%$ or systolic $\text{BP} < 90\text{ mmHg}$ (indicative of hypovolemic shock/hemorrhage).
• Urinary Output: Verify urine output is $\ge 30\text{ mL/hr}$.
2. Prevention of Postoperative Pulmonary Complications
Atelectasis (Alveolar Collapse): The most common cause of early postoperative fever ($24\text{--}48\text{ hours}$ post-op). Characterized by fine crackles and diminished breath sounds at lung bases.
Prevention & Care: Instruct client on Incentive Spirometry ($10\text{ times/hr}$ while awake), diaphragmatic deep breathing, controlled coughing while splinting surgical incisions with a pillow, and early post-op ambulation.
Surgical Wound Complications
5. Surgical Wound Dehiscence vs. Wound Evisceration
Surgical wound disruption typically occurs 6 to 8 days postoperatively, especially in clients with risk factors such as obesity, diabetes, malnutrition, chronic coughing, or abdominal distension.
| Complication |
Pathological Definition |
Immediate Priority Nursing Interventions |
| Wound Dehiscence |
Partial or total separation of outer surgical incision layers without organ protrusion. Client often reports a "popping" or "giving way" sensation accompanied by serosanguineous drainage. |
Place client in low Fowler's position with knees flexed. Apply sterile saline-moistened dressings over incision. Notify surgeon. Instruct client to avoid coughing or straining. |
| Wound Evisceration |
Protrusion of internal visceral organs (e.g., bowel loops) through a completely disrupted surgical wound incision. Medical Surgical Emergency! |
- Call for immediate assistance and notify surgeon/OR.
- Place client in low Fowler's position with knees flexed to relieve abdominal wall tension.
- Cover exposed organs with sterile non-adherent dressings saturated with warm 0.9% Normal Saline.
- NEVER attempt to re-insert exposed organs.
- Monitor vital signs for hypovolemic shock; keep client NPO for emergency surgery.

NCLEX / ATI Board Style Question
Clinical Practice Drill
Domain: Intraoperative Safety / Malignant Hyperthermia
Question: During an abdominal surgical procedure under general anesthesia, the circulating nurse observes an abrupt rise in the client's end-tidal carbon dioxide ($\text{EtCO}_2$) level, severe sinus tachycardia, and masseter muscle rigidity. Which of the following medications should the nurse prepare to administer immediately?
A) IV Atropine Sulfate
Option A
B) IV Dantrolene Sodium
Correct Answer ✓
C) IV Succinylcholine
Option C
D) IV Naloxone
Option D
Clinical Rationale:
Correct Answer: B (IV Dantrolene Sodium). The client is exhibiting classic early manifestations of Malignant Hyperthermia (MH)—an unexpected surge in $\text{EtCO}_2$, sinus tachycardia, and masseter muscle rigidity. IV Dantrolene Sodium is the specific skeletal muscle relaxant antidote that acts directly on Ryanodine receptors to inhibit calcium release from the sarcoplasmic reticulum, halting the hypermetabolic crisis.
Distractor Analysis: Atropine (Option A) would worsen tachycardia. Succinylcholine (Option C) is a triggering agent for MH and is strictly contraindicated. Naloxone (Option D) reverses opioids, not MH.
Frequently Asked Questions
High-Intent Perioperative Queries
What should the nurse do if the client expresses confusion about surgery after signing the consent form?
The nurse must hold pre-anesthetic medications and immediately notify the operating surgeon. The surgeon is legally required to return and explain the surgical procedure to the client until clear understanding is achieved.
Why is a client placed in low Fowler's position with knees flexed during a surgical evisceration?
Positioning the client in low Fowler's ($15\text{--}30^\circ$) with knees bent relaxes the abdominal muscle wall, reducing intra-abdominal pressure and tension on the disrupted surgical incision line, which minimizes further organ protrusion.
