burns - Nursing Case Study

Pathophysiology

• Primary mechanism: Thermal injury causes protein denaturation and cellular membrane disruption, leading to cell death and tissue necrosis. This initiates an inflammatory response, releasing cytokines and vasoactive mediators, resulting in increased vascular permeability and edema.

• Secondary mechanism: Systemic inflammatory response syndrome (SIRS) occurs due to the extensive release of inflammatory mediators, leading to widespread endothelial damage and capillary leak. This can result in hypovolemia, hypoperfusion, and potential shock, aggravating organ dysfunction.

• Key complication: Burn-induced immunosuppression from systemic inflammation increases susceptibility to infections, while prolonged hypoperfusion and shock can precipitate multi-organ failure, severe sepsis, and potentially lethal outcomes.

Section 1

New Diagnostic Results:

Following the initial stabilization efforts in the emergency department, the patient undergoes a series of diagnostic tests to assess the extent of systemic involvement and guide further treatment. Blood work reveals a significant leukocytosis with a white blood cell count of 18,000/mm³, indicating an acute inflammatory response. Serum lactate levels are elevated at 4.5 mmol/L, suggesting tissue hypoperfusion and possible early septic shock. Renal function tests show a concerning rise in creatinine to 2.2 mg/dL, indicating acute kidney injury likely due to hypovolemia and reduced perfusion. Liver function tests reveal elevated transaminases, with AST at 150 U/L and ALT at 180 U/L, hinting at hepatic stress possibly from the systemic inflammatory response or hypoxic injury.

Further imaging, including a chest X-ray, shows bilateral pulmonary infiltrates, raising the suspicion of acute respiratory distress syndrome (ARDS) secondary to systemic inflammatory response syndrome (SIRS). An arterial blood gas analysis reveals a pH of 7.28, PaCO2 of 55 mmHg, and PaO2 of 60 mmHg on 100% oxygen, indicating respiratory acidosis with severe hypoxemia, necessitating urgent consideration for advanced respiratory support, potentially mechanical ventilation. Electrolyte panels show hyponatremia at 128 mmol/L and hyperkalemia at 5.8 mmol/L, adding complexity to the fluid resuscitation strategy.

These diagnostic findings underscore the severity of the patient's condition, highlighting the need for a multidisciplinary approach to manage the burn shock, prevent progression to multi-organ dysfunction, and address potential infectious complications. The team must engage in critical thinking to balance fluid resuscitation with the risk of exacerbating the pulmonary condition, optimize oxygen delivery to prevent further tissue damage, and initiate broad-spectrum antibiotics pending culture results to mitigate the risk of sepsis.

Section 2

Change in Patient Status:

As the critical care team continues to monitor the patient, there is a notable change in status. Over the next 12 hours, the patient's hemodynamic stability deteriorates despite aggressive fluid resuscitation. Blood pressure begins to fall, with readings dropping to 85/50 mmHg, and heart rate increases to 130 beats per minute, indicating worsening shock. The patient exhibits altered mental status, becoming increasingly disoriented and agitated, likely due to inadequate cerebral perfusion and worsening hypoxemia. Urine output significantly decreases to less than 0.3 mL/kg/hr, reinforcing concerns about acute kidney injury progression.

In addition to hemodynamic instability, the patient's respiratory function declines further. Despite supplemental oxygen, oxygen saturation levels drop to 88%, indicating refractory hypoxemia. Auscultation of the lungs reveals diminished breath sounds and crackles throughout, consistent with worsening pulmonary edema and ARDS. Repeat arterial blood gas analysis shows a pH of 7.25, PaCO2 of 60 mmHg, and PaO2 of 55 mmHg, further confirming respiratory failure. The decision is made to initiate mechanical ventilation to improve oxygenation and support respiratory function.

The patient's metabolic status also shows signs of deterioration. Repeat electrolyte panels reveal persistent hyponatremia at 126 mmol/L and worsening hyperkalemia at 6.2 mmol/L, complicating the fluid and electrolyte management plan. Lactate levels remain elevated at 5.0 mmol/L, indicating ongoing tissue hypoperfusion and metabolic acidosis. These developments demand urgent reassessment of the current treatment strategy, with a focus on optimizing hemodynamic support, refining ventilatory management, and addressing the underlying causes of the metabolic derangements. The team must closely collaborate to adjust interventions dynamically, ensuring that the multifaceted needs of the patient are met promptly.

Section 3

New Complications:

As the critical care team continues to manage the patient's deteriorating condition, a new complication arises, further complicating the clinical picture. The patient begins to develop signs of disseminated intravascular coagulation (DIC), a serious condition often triggered by the extensive inflammatory response and tissue damage associated with severe burns. Laboratory results show a marked decrease in platelet count to 50,000/μL, prolonged prothrombin time (PT) at 18 seconds, and an elevated D-dimer level, indicative of widespread clotting activity and subsequent bleeding risk. Clinically, the patient exhibits new-onset petechiae and ecchymoses, particularly in areas of pressure, highlighting the increased bleeding tendency.

The emergence of DIC necessitates a careful reevaluation of the patient's treatment plan. The team must balance the need for anticoagulation to manage microthrombi formation with the risk of exacerbating bleeding. This complication further challenges the current hemodynamic support strategies, as the patient's blood pressure remains low despite vasopressor therapy, now compounded by potential blood loss. Additionally, the ongoing metabolic acidosis and electrolyte imbalances require precise adjustments in fluid and electrolyte therapy, with close monitoring to prevent worsening cardiac and renal function.

In response to DIC, the team initiates a targeted approach, including the administration of fresh frozen plasma and cryoprecipitate to replace clotting factors, along with careful titration of vasopressors to maintain adequate perfusion. The patient's ventilatory support is adjusted to compensate for the increased metabolic demand and to optimize oxygen delivery. This complex interplay of interventions underscores the need for vigilant monitoring and rapid, informed decision-making to stabilize the patient and prevent further complications. As the team works to manage these new challenges, they continue to anticipate potential complications, maintaining a proactive approach to the ever-evolving clinical landscape.

Section 4

As the team continues to address the newly diagnosed disseminated intravascular coagulation (DIC), they closely monitor the patient's response to the initiated interventions. Over the next 24 hours, the patient exhibits a mixed response to the treatment. Vital signs reveal persistent hypotension with blood pressure readings averaging 85/50 mmHg despite titration of vasopressors, indicating inadequate perfusion. Heart rate remains tachycardic at 125 beats per minute, suggesting ongoing cardiovascular strain. The patient's respiratory rate is elevated at 30 breaths per minute, and arterial blood gas analysis shows a pH of 7.29, PaCO2 of 55 mmHg, and HCO3- of 18 mmol/L, confirming persistent metabolic acidosis with a compensatory respiratory response.

Laboratory results indicate partial improvement in coagulation parameters, with platelet count rising slightly to 70,000/μL and PT decreasing to 16 seconds. However, fibrinogen levels remain low, prompting the continuation of cryoprecipitate replacement. The patient still demonstrates significant bleeding risk, as evidenced by continued oozing from intravenous sites and worsening ecchymoses in dependent areas. Renal function tests show a concerning trend, with creatinine levels rising to 2.1 mg/dL, indicating potential acute kidney injury, likely secondary to hypoperfusion and metabolic derangements.

Amid these developments, the clinical team is faced with the challenge of optimizing fluid management to support both renal perfusion and hemodynamic stability without exacerbating the risk of fluid overload. They must also reconsider the balance of anticoagulation therapy, carefully weighing the risk of thrombotic versus hemorrhagic complications. Furthermore, the team discusses the potential need for renal replacement therapy if renal function continues to decline. This complex interplay of factors requires advanced critical thinking and clinical judgment to prioritize interventions that will stabilize the patient while anticipating and preventing further complications. The team remains vigilant, prepared for rapid adjustments in the therapeutic plan as the patient's condition evolves.

Section 5

New Complications:

Over the next 12 hours, the patient's condition takes a turn with the emergence of new complications, further taxing the already strained medical team. The patient begins to exhibit signs of acute respiratory distress syndrome (ARDS), marked by increasing oxygen requirements and worsening hypoxemia. Oxygen saturation levels plummet to 85% on a non-rebreather mask, necessitating urgent escalation to mechanical ventilation. A chest X-ray reveals bilateral infiltrates consistent with pulmonary edema, raising concerns of fluid overload despite careful monitoring of fluid balance. This complication complicates the delicate equilibrium the team is attempting to maintain between fluid resuscitation for renal perfusion and the risk of pulmonary complications.

Simultaneously, the patient's neurological status deteriorates, with episodes of confusion and disorientation noted during assessments. The Glasgow Coma Scale (GCS) score drops from 14 to 10, prompting an urgent CT scan of the head to rule out intracranial hemorrhage or other acute neurological events. The imaging reveals no acute intracranial pathology, suggesting that the altered mental status might be secondary to metabolic derangement, hypoxia, or potential sepsis. These developments necessitate a reevaluation of the current therapeutic approach, highlighting the need for a multidisciplinary strategy involving critical care, nephrology, and hematology specialists to address these evolving challenges. The team prepares for the possibility of initiating renal replacement therapy and considers adjusting ventilatory support strategies to improve oxygenation while minimizing further lung injury.
