## 문제

A nurse is caring for a client who underwent colectomy for colon cancer 3 days ago. Which nursing intervention is most important to prevent postoperative complications?

The client is recovering from esophagectomy with gastric pull-up procedure and has a nasogastric tube in place.

## 보기

1. Encourage early ambulation and deep breathing exercises
2. Monitor for signs of anastomotic leak and report immediately
3. Maintain strict intake and output documentation
4. Position the client in semi-Fowler's position and monitor respiratory status **✔ 정답**

**정답: 4**

## 해설

Positioning in semi-Fowler's position and monitoring respiratory status is critical to prevent aspiration and respiratory complications post-esophagectomy. Other interventions are important but less immediate for life-threatening risks.

Postoperative Priority Setting: Esophagectomy with Gastric Pull-Up

The question presents a client on postoperative day 3 following an esophagectomy with a gastric pull-up procedure, and a nasogastric tube is in place. When prioritizing care, the nurse must focus on the complication with the highest immediate mortality risk. According to the provided evidence, aspiration is the most significant direct postoperative threat in this population, primarily due to the profound anatomical alterations from the surgery [2].

Why Option 4 is the Priority

Positioning the client in semi-Fowler's position and monitoring respiratory status directly mitigates the risk of aspiration. The gastric pull-up procedure fundamentally disrupts the normal anti-reflux mechanisms, placing the gastric conduit in the chest under positive pressure relative to the negative-pressure thoracic cavity. This creates a high risk for silent regurgitation and aspiration of gastric contents, which can rapidly lead to aspiration pneumonia, a major cause of postoperative morbidity and mortality [2, 3]. Maintaining a semi-Fowler's position uses gravity to keep gastric contents in the conduit, while vigilant respiratory monitoring allows for early detection of aspiration signs such as tachypnea, decreased oxygen saturation, or new-onset crackles. This intervention is a continuous, preventive safety measure that takes precedence over other assessments.

Analysis of Other Options

-   Option 1: Encouraging early ambulation and deep breathing exercises is a standard postoperative intervention to prevent atelectasis and venous thromboembolism. While important for general recovery, it does not address the most lethal, surgery-specific risk of aspiration in an esophagectomy patient. A client can ambulate and still suffer a fatal aspiration event if positioning and airway protection are not prioritized.

-   Option 2: Monitoring for signs of an anastomotic leak is a critical nursing action for this client. A leak can lead to mediastinitis and sepsis. However, a leak is a less frequent acute event compared to the constant, ongoing risk of aspiration with every position change or reflux episode. The immediate, life-threatening respiratory compromise from aspiration requires a more continuous preventive strategy, making respiratory positioning the higher priority intervention.

-   Option 3: Maintaining strict intake and output documentation is essential for monitoring fluid balance and renal function, especially with a nasogastric tube in place. This is a standard component of care but is not the priority action for preventing the most immediate and severe complication. The risk of aspiration and subsequent respiratory failure is a more time-sensitive threat than the slower-developing complications of fluid imbalance.

The evidence confirms that anatomical changes from esophagectomy are the primary driver of postoperative aspiration risk [2]. Furthermore, complications like delayed gastric conduit emptying (DGCE), which occurs in a significant percentage of patients, can exacerbate this risk by increasing intraluminal pressure and the volume of retained gastric contents available for reflux and aspiration [3]. The nurse's first line of defense is a simple, high-impact intervention: proper positioning and continuous respiratory vigilance.References (research sources)

## 임상 시나리오

Post-Esophagectomy Aspiration PreventionPriority Nursing Action for Gastric Pull-Up
The highest immediate postoperative risk after esophagectomy with gastric pull-up is aspiration, not anastomotic leak. The surgery destroys the lower esophageal sphincter, placing the intrathoracic stomach under positive pressure, which promotes silent regurgitation.

Maintain the patient in a semi-Fowler's position (head of bed elevated 30-45 degrees) at all times. This uses gravity to keep gastric contents in the conduit and is a continuous preventive measure.

CautionNever place the patient flat or in Trendelenburg position. Monitor respiratory status vigilantly for early signs of aspiration: tachypnea, decreased SpO2, or new-onset crackles. Keep suction equipment at the bedside and verify NG tube patency and placement per order, but never manipulate or irrigate the NG tube without a specific surgeon's order due to risk of disrupting the fresh anastomosis.

## 핵심 개념

- **Gastric Pull-Up** — Surgical procedure where the stomach is mobilized into the thoracic cavity to replace a resected esophagus, disrupting normal anti-reflux mechanisms.
- **Semi-Fowler's Position** — Position with the head of the bed elevated 30-45 degrees, using gravity to reduce the risk of aspiration by keeping gastric contents down.
- **Anastomotic Leak** — Leakage of contents from a surgical connection site, a serious complication after esophagectomy that typically manifests around postoperative day 5-7.
- **Aspiration Pneumonia** — Lung infection caused by inhaling foreign material like gastric contents, a major cause of morbidity and mortality after esophagectomy.
