Managing Postoperative Complications and Nursing Care

Identifying and Managing Complications

Complications can arise at any stage. Nurses must categorize these risks to prioritize interventions.

Respiratory Complications: Atelectasis and Hypoxia

Atelectasis—the collapse of part or all of a lung—is a significant risk due to reduced gas exchange. This can lead to hypoxia, a state of low oxygen saturation.

To prevent atelectasis and encourage airway clearance, nurses should implement:

1. Incentive Spirometry: Patients should use this device to reestablish lung function, performing approximately 10 repetitions per hour and holding each breath for 3–5 seconds.

2. Cough and Deep Breathing: These exercises should be performed every 2 hours post-surgery to prevent secretions from building up, though they must be used with caution in patients recovering from brain or eye surgery.

3. Early Ambulation: Moving the patient helps expand the lungs and prevent stasis.

Cardiovascular Complications: DVT and Pulmonary Embolism

Thromboembolism, specifically Deep Vein Thrombosis (DVT), is a major postoperative threat. If a clot breaks loose, it can travel to the lungs, causing a life-threatening Pulmonary Embolism (PE).

Nursing Tip: DVT Prevention The most effective way to prevent DVT is a combination of early ambulation and the use of mechanical prophylaxis such as Sequential Compression Devices (SCDs).

Surgical Site Complications: Infection and Dehiscence

The integrity of the incision is a primary nursing priority.

• Infection: Manifests as redness, swelling, or purulent drainage. Management includes wound cultures, antibiotics, and meticulous wound care.

• Dehiscence: This is the partial or total separation of wound edges. If suspected, the nurse must perform an immediate assessment and notify the healthcare provider, as the patient may require restitching or staples.

GI and GU Management

Postoperative patients often experience slowed motility due to anesthesia and opioid use.

• Gastrointestinal (GI): Nurses monitor for Ileus (lack of bowel motility). Interventions include abdominal assessments, maintaining NPO status with IV fluids, or using a Nasogastric (NG) tube for decompression. Bowel function is considered returned once the patient passes flatus.
• Genitourinary (GU): Oliguria (low urine output) and urinary retention are common risks. Nurses must monitor Intake and Output (I&O) closely, manage hydration via IV fluids, and may need to perform catheterization if necessary.

Postoperative Nursing Priorities

As a patient transitions from the PACU (Phase I) to a general unit (Phase II), the nurse's assessment strategy must be systematic.

The Aldrete Score

To ensure a patient is safe for discharge from the PACU, nurses use the Aldrete Score. This tool evaluates five criteria: Activity, Respiration, Circulation, Consciousness, and Oxygen Saturation.

A score of $\ge 9$ indicates the patient is safe for discharge from the PACU.

Pain Management

Pain is often referred to as the "6th vital sign". Nurses must assess for physical manifestations such as facial expressions, moaning, or changes in vital signs (increased BP, pulse, or RR).

• Pharmacological: Patients may use a Patient-Controlled Analgesia (PCA) pump, which allows them to self-administer small, safe doses of medication.

• Nonpharmacological: Complementary therapies like guided imagery, music therapy, and massage can enhance conventional medical care and promote holistic healing.

Exam Alert: Pain Assessment Always remember that undertreatment of pain can occur due to clinician fear of addiction or cultural attitudes. Continuous assessment is a nursing priority.
