## 문제

A nurse is caring for a client receiving peritoneal dialysis. Which assessment finding would be the most concerning and require immediate intervention?

## 보기

1. Cloudy dialysate return with abdominal pain and fever
2. Bright red blood in the dialysate return fluid **✔ 정답**
3. Decreased urine output over the past 24 hours
4. Mild cramping during dialysate infusion

**정답: 2**

## 해설

Bright red blood in dialysate return indicates active intra-abdominal bleeding, a medical emergency requiring immediate cessation of dialysis and intervention to prevent hemorrhage and shock. Cloudy dialysate suggests peritonitis, which is serious but less immediately life-threatening than active bleeding.

Clinical Reasoning Analysis

The most concerning assessment finding requiring immediate intervention is bright red blood in the dialysate return fluid. While all options represent deviations from normal, the priority setting follows the hemodynamic stability and life-threatening bleeding risk. Bright red blood indicates active, rapid hemorrhage, which can quickly lead to hypovolemic shock, making this a higher priority than infection (option 1) in the acute moment of assessment.

Pathophysiology and Clinical Significance of Hemoperitoneum

In a patient receiving peritoneal dialysis (PD), the presence of bright red blood in the dialysate signifies active intra-abdominal bleeding, a condition known as hemoperitoneum. Unlike the faintly pink-tinged effluent that can be common, especially in menstruating women or after catheter placement, frank red blood points to a vascular injury or a ruptured viscus. The immediate danger is rapid blood loss into the peritoneal cavity, which is a large potential space capable of holding a significant volume of blood, leading to hypovolemia and hemodynamic instability.

The urgency is underscored by the fact that patients with end-stage renal disease (ESRD) are at a fundamentally higher risk for catastrophic events. One precipitating factor for hemoperitoneum, as highlighted in the literature, is cardiopulmonary resuscitation (CPR). The need for CPR in hospitalized ESRD patients is almost 20 times higher than in the general population [3]. The mechanical force of chest compressions can cause rare intra-abdominal complications, including splenic or hepatic lacerations, leading to hemoperitoneum in PD patients [3]. This connection reinforces why a finding of active bleeding must be treated as a potential surgical emergency until proven otherwise.

Analysis of the Other Options

- **Cloudy dialysate return with abdominal pain and fever**

This presentation is the classic triad for peritonitis, a serious infectious complication of PD. While it requires prompt intervention, including sending dialysate for cell count and culture and initiating empiric antibiotics, it does not typically cause rapid hemodynamic collapse in the same immediate timeframe as an active hemorrhage. Recent advances in care protocols have significantly improved the prevention and management of such infectious complications . The priority is to first rule out or manage a life-threatening bleed.

- **Decreased urine output over the past 24 hours**

This finding indicates a worsening of residual renal function, which is an expected and gradual progression in a patient with stage 5 chronic kidney disease on dialysis . It is a chronic management issue, not an acute, life-threatening emergency requiring immediate intervention.

- **Mild cramping during dialysate infusion**

This is a common non-infectious complication of PD, often related to the infusion of cool dialysate, rapid inflow rates, or catheter tip irritation. It is managed by ensuring the dialysate is warmed to body temperature and slowing the infusion rate. It does not pose an immediate threat to the patient's life.

Nursing Priority and Immediate Actions

The nurse's immediate focus upon seeing bright red blood in the dialysate must be a rapid assessment of the patient's hemodynamic status. This includes monitoring vital signs for hypotension and tachycardia, assessing for signs of shock (pallor, cool clammy skin, altered mental status), and checking a complete blood count if ordered. The nurse should immediately notify the healthcare provider, as the patient may require emergent fluid resuscitation, blood products, and a surgical evaluation to identify and control the bleeding source. The mechanical complications of PD, such as catheter malposition and dysfunction, are significant challenges to long-term therapy , but a life-threatening noninfectious event like a massive hemoperitoneum takes absolute priority, especially in vulnerable populations like infants where such events can escalate rapidly .References (research sources)

## 임상 시나리오

Recognizing Hemoperitoneum in Peritoneal DialysisImmediate Action for Active Intra-Abdominal Hemorrhage
The most critical finding in a patient on peritoneal dialysis is bright red blood in the dialysate, indicating active hemoperitoneum. This signifies rapid blood loss into the peritoneal cavity, which can quickly lead to hypovolemic shock.

Prioritize this over peritonitis (cloudy fluid, pain, fever) in the acute moment. While peritonitis is a serious infection, active hemorrhage poses an immediate threat to hemodynamic stability. Patients with ESRD are at higher risk for catastrophic events like hemorrhage.

CautionDo not dismiss bright red blood as a minor issue. The peritoneal cavity can hold a large volume of blood. Immediately assess vital signs for signs of shock, clamp the catheter, and notify the provider for urgent surgical evaluation.

## 핵심 개념

- **Hemoperitoneum** — Accumulation of blood in the peritoneal cavity, presenting as bright red effluent in PD patients and indicating active intra-abdominal bleeding.
- **Peritonitis** — Inflammation of the peritoneum, a common PD complication typically presenting with cloudy dialysate, abdominal pain, and fever.
- **Hypovolemic Shock** — A life-threatening condition caused by rapid fluid or blood loss, leading to inadequate tissue perfusion and hemodynamic instability.
