pressure injury - Nursing Case Study

Pathophysiology

• Primary mechanism: Prolonged pressure over bony prominences compresses blood vessels, leading to ischemia. This reduces oxygen and nutrient supply to tissues, causing cell death and tissue necrosis.

• Secondary mechanism: Shear forces exacerbate tissue damage by distorting capillaries, further impairing blood flow. This mechanical stress disrupts cellular integrity and promotes deeper tissue injury.

• Key complication: Necrotic tissue becomes susceptible to infection, potentially leading to systemic complications such as sepsis and multi-organ failure, significantly increasing morbidity and mortality in vulnerable patients.

Section 1

As the nursing team proceeds with the initial assessment, they observe that the sacral pressure ulcer has advanced to a stage 4, characterized by full-thickness skin and tissue loss with exposed bone, tendon, or muscle. The ulcer is surrounded by erythematous tissue, and the wound bed is covered with slough and eschar, indicating the presence of necrotic tissue. The surrounding skin is warm to the touch and exhibits signs of cellulitis. A wound culture is obtained, and empirical broad-spectrum antibiotics are initiated while awaiting results. The patient’s skin turgor is poor, and she exhibits signs of dehydration, likely due to insensible fluid loss exacerbated by fever and tachypnea.

The nursing team notes that the patient is exhibiting altered mental status, oscillating between confusion and lethargy, suggesting possible septic encephalopathy. Further lab tests reveal elevated white blood cell count, with a left shift indicating a severe bacterial infection. Blood cultures are drawn to identify potential bacteremia. Additionally, the patient's renal function tests show worsening kidney function, with a significant increase in blood urea nitrogen (BUN) and creatinine levels, suggesting acute kidney injury on top of her chronic kidney disease. Lactate levels are elevated, confirming tissue hypoperfusion and hinting at the early stages of septic shock.

Given these findings, the interdisciplinary team convenes to reassess the management plan. Aggressive fluid resuscitation is prioritized to address hypotension and support perfusion, while careful monitoring of the patient's fluid status is essential due to her compromised renal function. The critical care team considers the need for vasopressor support if blood pressure fails to improve with fluids alone. Meanwhile, consultations with a wound care specialist, nephrologist, and infectious disease expert are sought to tailor the therapeutic approach, optimize wound healing, and manage the complex interplay of systemic infections and organ dysfunction. The evolving clinical picture underscores the need for vigilant monitoring and rapid response to changes in the patient’s status, as the risk of progression to multi-organ failure remains high.

Section 2

As the interdisciplinary team implements the management plan, the patient's condition undergoes a significant change. Despite aggressive fluid resuscitation, the patient's blood pressure continues to decline, with systolic readings now consistently in the 80s mmHg, necessitating the initiation of vasopressor support to maintain adequate perfusion. The patient is started on norepinephrine infusion, which stabilizes her blood pressure temporarily. However, her heart rate remains elevated at 120-130 beats per minute, and her respiratory rate is persistently high at 28 breaths per minute, indicating ongoing stress and possible respiratory compromise. The patient's oxygen saturation is borderline at 92% on a high-flow nasal cannula, prompting consideration for escalation to non-invasive ventilation.

The latest lab results reveal a concerning trend: the patient's lactate levels have risen to 5 mmol/L, indicating worsening tissue hypoperfusion. Her serum potassium has also increased to 5.8 mmol/L, raising concerns about hyperkalemia due to the combination of acute kidney injury and possible tissue breakdown from necrosis. This electrolyte imbalance poses a risk for cardiac arrhythmias, necessitating immediate intervention with calcium gluconate and insulin-glucose therapy to stabilize her cardiac function. Moreover, the wound culture results return, identifying a multi-drug resistant organism, necessitating a change in antibiotic therapy to include agents with coverage specific to the pathogen.

The nursing team remains vigilant for signs of further deterioration, recognizing the potential for progression to respiratory failure and the need for mechanical ventilation. There is a heightened focus on hourly assessments of vital signs, urine output, and mental status to detect subtle changes that may indicate worsening sepsis or multi-organ dysfunction. Continuous collaboration with the critical care team and specialists is essential to adapt the patient's treatment plan to her rapidly evolving condition. The complexity of her case underscores the critical need for multidisciplinary coordination, timely interventions, and advanced critical thinking to navigate the challenges of severe sepsis and its complications.

Section 3

As the healthcare team continues their vigilant monitoring, the patient's condition takes another turn. Despite the initiation of vasopressor support and adjustments in fluid management, her heart rate remains persistently elevated, and her respiratory rate shows no signs of improvement. The decision is made to escalate respiratory support to non-invasive ventilation, but even with this intervention, her oxygen saturation struggles to maintain above 90%. As the critical care nurse assesses her respiratory status, there is an audible wheeze upon auscultation, and her accessory muscles are visibly strained, indicating increased respiratory effort and potential impending respiratory failure.

In parallel, a repeat arterial blood gas (ABG) test reveals a concerning development: the patient's pH has dropped to 7.28, with a PaCO2 of 50 mmHg and HCO3- of 18 mEq/L, indicating a mixed respiratory and metabolic acidosis. These findings suggest worsening hypoventilation and potential acute respiratory distress syndrome (ARDS) secondary to sepsis. In response, the interdisciplinary team initiates discussions about transitioning to invasive mechanical ventilation to ensure adequate oxygenation and ventilation, prevent further respiratory muscle fatigue, and allow for more precise control over her respiratory parameters.

Simultaneously, the patient's renal function continues to decline, as evidenced by a rising creatinine level now at 3.5 mg/dL. The nursing team notes a decrease in urine output, dropping to less than 20 mL/hour, raising concerns about worsening acute kidney injury. This decline necessitates an urgent nephrology consultation to evaluate the need for renal replacement therapy, such as continuous renal replacement therapy (CRRT), to manage fluid overload and electrolyte imbalances effectively. The complexity of the patient's condition underscores the importance of ongoing, dynamic reassessment and timely intervention to address the multifaceted challenges posed by severe sepsis and its rapidly evolving complications.

Section 4

As the critical care team closely monitors the patient's condition, a new set of diagnostic results provides further insight into her deteriorating status. A follow-up chest X-ray reveals bilateral infiltrates consistent with developing acute respiratory distress syndrome (ARDS), confirming the suspicion of worsening pulmonary involvement secondary to severe sepsis. This finding, in conjunction with the patient's persistently low oxygen saturation despite non-invasive ventilation, fuels the decision to proceed with intubation and invasive mechanical ventilation. The team prepares for the procedure, ensuring all necessary equipment and medications are ready to minimize the risk of peri-intubation complications.

In parallel, the patient's hemodynamic status continues to be unstable. Her blood pressure remains low despite maximal vasopressor support, with readings consistently around 82/50 mmHg. The team decides to initiate an additional vasopressor agent to optimize her mean arterial pressure and improve perfusion to vital organs, particularly the kidneys. Despite these aggressive measures, her urine output remains critically low, and her creatinine level climbs further to 4.2 mg/dL, heightening the urgency for renal support. A nephrology consult confirms the need for continuous renal replacement therapy (CRRT) to address her acute kidney injury and manage fluid overload, as traditional diuretic therapy proves ineffective.

In the midst of these interventions, new complications arise. The patient develops a rising body temperature of 39.5°C (103.1°F), accompanied by leukocytosis, with a white blood cell count of 18,000/mm³, indicating a possible new or unresolved infectious process. Blood cultures are drawn, and broad-spectrum antibiotics are adjusted to cover a wider range of potential pathogens while awaiting culture results. The team remains vigilant, continuously reassessing and adjusting the plan of care based on the evolving clinical picture, emphasizing the need for comprehensive, multidisciplinary collaboration to navigate the complexities of her condition.

Section 5

As the critical care team continues to navigate the complexities of the patient's condition, a new complication arises. The patient's skin integrity further deteriorates, and she develops a Stage III pressure injury on her sacrum, characterized by full-thickness skin loss and visible adipose tissue. This development underscores the importance of meticulous pressure injury prevention and management in critically ill patients, particularly those with compromised mobility and perfusion. The wound care team is promptly consulted to assess the extent of the injury and to develop a comprehensive wound management plan. They determine that negative pressure wound therapy (NPWT) may be beneficial in promoting healing and reducing bacterial burden, but the patient's hemodynamic instability presents a significant challenge to implementing this intervention without exacerbating her condition.

In parallel, the patient's laboratory results reveal a concerning trend in her metabolic profile. Her lactic acid level has risen to 5.8 mmol/L, indicating worsening tissue hypoperfusion and an increased metabolic demand that her body struggles to meet. The elevated lactate level, combined with persistent hypotension and oliguria, signals the progression to septic shock and necessitates an urgent reassessment of her therapeutic regimen. The team deliberates the potential to increase fluid resuscitation efforts cautiously, balancing the risk of fluid overload given her ARDS and renal impairment. Continuous hemodynamic monitoring and point-of-care ultrasound are utilized to guide fluid management more precisely, while ongoing vasopressor titration aims to stabilize her cardiovascular status.

Amid these challenges, the multidisciplinary team remains vigilant, recognizing the need for refined clinical reasoning and judgment in managing this complex case. They prioritize frequent reassessment of the patient's evolving status, engaging in regular huddles to ensure that all aspects of her care are aligned with the latest clinical insights. As they await additional culture results and evaluate the effectiveness of the current antibiotic regimen, the team remains poised to adjust their strategy, emphasizing the importance of adaptive, patient-centered care in the face of severe sepsis and its cascading complications.
