## 문제

The nurse is monitoring a post-operative bariatric surgery patient for potential complications. Which nursing intervention should be the priority?

## 보기

1. Monitor anastomotic leak signs **✔ 정답**
2. Encourage early ambulation every 2 hours
3. Administer prescribed antiemetics for nausea
4. Provide small frequent meals as tolerated

**정답: 1**

## 해설

Anastomotic leak is the most life-threatening complication post-bariatric surgery, requiring immediate detection. Other interventions (ambulation, antiemetics, small meals) are important but less urgent.

Priority Nursing Intervention for Post-Operative Bariatric Surgery

The priority nursing intervention is to monitor for anastomotic leak signs. In the immediate postoperative period following bariatric surgery, the nurse must apply the Airway, Breathing, Circulation (ABC) framework alongside a focused assessment for the most life-threatening surgical complication. An anastomotic leak, which involves the escape of gastrointestinal contents from a surgical connection site, can rapidly progress to peritonitis, sepsis, and hemodynamic instability. This complication directly threatens the patient's circulation and overall physiological stability, making its early detection the highest clinical priority.

The critical nature of this assessment is underscored by evidence from enhanced recovery protocols. A systematic review and meta-analysis evaluating Enhanced Recovery After Surgery (ERAS) protocols in bariatric care identified anastomotic leak as a primary nursing-sensitive complication that these protocols aim to reduce [3]. The review highlights that while ERAS pathways promote interventions like early oral feeding, a cautious approach persists precisely because of the safety concern surrounding this very complication, particularly after complex procedures like gastric bypass [3]. The nurse's vigilant surveillance for early, often subtle, signs such as unexplained tachycardia (heart rate > 120 bpm), tachypnea, new-onset shoulder pain, increasing abdominal pain, or a change in the character of drain output is the cornerstone of preventing catastrophic deterioration.

While the other listed interventions are important components of postoperative care, they do not supersede the immediate threat of an anastomotic leak. A quality improvement study on implementing an ERAS protocol in a community hospital setting describes a structured, multimodal pathway that includes standardized postoperative monitoring to enhance recovery and promote safer outcomes [1]. This pathway integrates various elements, but the foundational safety component remains the early identification of surgical complications. Encouraging early ambulation every 2 hours is a key strategy for preventing venous thromboembolism and promoting gastrointestinal motility, and administering prescribed antiemetics is crucial for comfort and preventing retching that could stress suture lines. However, these are secondary to ensuring the patient is not developing a systemic infection from a leak. Similarly, providing small frequent meals is a later-stage nutritional intervention that is contraindicated until a leak has been definitively ruled out, as early oral feeding in the presence of a leak would exacerbate the contamination of the peritoneal cavity. The nurse's immediate, prioritized action is to perform a focused clinical assessment to detect the earliest manifestations of this potentially fatal complication.References (research sources)

## 임상 시나리오

Post-Op Bariatric Priority: Leak SurveillanceEarly detection of anastomotic leak prevents fatal sepsis
Apply the ABC framework postoperatively. An anastomotic leak threatens circulation via rapid third-spacing and sepsis, making it the priority over ambulation or diet.

Monitor for subtle early signs: unexplained tachycardia (>120 bpm), tachypnea, new-onset shoulder pain, or increasing abdominal pain. A change in mental status or oliguria may be the first indicator.

CautionDo not dismiss tachycardia as simple pain or anxiety. In the bariatric patient, sustained heart rate elevation is a sentinel sign of leak until proven otherwise, often preceding fever or peritoneal signs.

## 핵심 개념

- **Anastomotic Leak** — Escape of GI contents from a surgical connection site, leading to peritonitis, sepsis, and hemodynamic instability; a priority assessment post-bariatric surgery.
- **ERAS Protocol** — Enhanced Recovery After Surgery; multimodal, evidence-based perioperative care pathways designed to reduce complications like anastomotic leaks and improve outcomes.
