burns, Thermal - Nursing Case Study

Pathophysiology

• Primary mechanism: Thermal burns cause direct tissue damage through the transfer of heat, leading to protein denaturation and cell membrane disruption, resulting in immediate cell death and coagulative necrosis.

• Secondary mechanism: The inflammatory response is triggered by the release of cytokines and other mediators from damaged cells, causing increased vascular permeability, edema, and further tissue injury as neutrophils and other immune cells infiltrate the burn site.

• Key complication: Systemic inflammatory response syndrome (SIRS) can occur in severe burns, leading to widespread vasodilation and capillary leak, potentially resulting in hypovolemic shock and multi-organ dysfunction if not promptly managed.

Section 1

As the medical team continues to monitor the patient, a change in his status becomes evident. Despite initial stabilization efforts, the patient begins to exhibit signs of worsening systemic inflammatory response. His temperature rises to 102.5°F, and his heart rate increases to 120 bpm. The blood pressure remains elevated at 160/95 mmHg, and his respiratory rate has climbed to 26 breaths per minute. The patient reports increased pain and discomfort, with the blisters on his arms and chest appearing more pronounced and beginning to rupture, exuding clear fluid.

The increase in vital signs, particularly the tachycardia and tachypnea, signals a potential complication arising from the burn injuries. Given his medical history of hypertension and Type 2 Diabetes, there is a growing concern about the risk of infection and delayed wound healing. A full blood panel is ordered, revealing a white blood cell count of 15,000/mm³, indicating a developing infection. Additionally, there is evidence of mild metabolic acidosis, with a blood pH of 7.33 and bicarbonate level of 20 mEq/L, suggesting that the patient is beginning to experience metabolic stress.

Recognizing the signs of potential sepsis, the healthcare team initiates broad-spectrum antibiotics, considering the patient's allergy to penicillin, and increases fluid resuscitation to address the risk of hypovolemic shock. The patient is also started on insulin therapy to manage elevated blood glucose levels due to stress hyperglycemia, common in burn patients and exacerbated by his diabetes. These interventions are critical as the team works to prevent progression to sepsis or organ dysfunction, underscoring the need for vigilant monitoring and timely treatment adjustments in the patient's ongoing care.

Section 2

As the healthcare team responds to the initial interventions, a change in the patient's status becomes apparent, prompting close re-evaluation. Over the next 24 hours, the patient’s temperature remains elevated, peaking at 103°F, and his heart rate continues to hover around 118 bpm. Despite increased fluid resuscitation, the patient shows signs of early acute kidney injury, evidenced by a rising serum creatinine level of 1.8 mg/dL from a baseline of 1.0 mg/dL, and decreased urine output to 20 mL per hour. This development raises concerns about the adequacy of renal perfusion and the risk of further complications from systemic inflammatory response syndrome (SIRS).

Clinically, the patient appears lethargic, with a persistent mild confusion that was not initially present. The areas of burn injury are now showing signs of cellulitis, with redness and warmth extending beyond the original wound margins. In light of these findings, the medical team considers the potential for worsening infection and sepsis progression, despite ongoing antibiotic therapy. The patient's blood glucose levels remain elevated, requiring frequent insulin adjustments, while his oxygen saturation has decreased to 92% on room air, prompting the need for supplemental oxygen. This change in status necessitates reevaluation of the treatment plan, focusing on optimizing antibiotic coverage and ensuring adequate organ support.

To address these evolving challenges, the team decides to escalate care by consulting with a nephrologist for potential renal support strategies and a wound care specialist to reassess the burn management approach. They also plan to broaden the spectrum of antibiotics after obtaining new wound cultures, given the apparent spread of infection and potential for resistant organisms. The clinical reasoning behind these steps reflects a proactive approach to stabilize the patient and prevent further deterioration, anticipating the next phase of care with a focus on mitigating systemic effects and supporting recovery.

Section 3

As the healthcare team closely monitors the patient's condition, new diagnostic results reveal significant changes in the patient's status. Blood cultures obtained previously now indicate the presence of methicillin-resistant Staphylococcus aureus (MRSA), confirming the suspicion of a resistant organism contributing to the cellulitis and systemic infection. This finding prompts the adjustment of antibiotic therapy to include vancomycin, tailored to target the MRSA infection effectively. Given the patient's declining oxygen saturation and signs of respiratory compromise, an arterial blood gas analysis is performed, revealing a mild respiratory acidosis with a pH of 7.32 and a partial pressure of carbon dioxide (PaCO2) of 48 mmHg, indicating an evolving respiratory issue likely secondary to the systemic inflammatory response.

The change in the patient's status necessitates a reassessment of his respiratory support needs. Supplemental oxygen is increased, and the team initiates continuous pulse oximetry to closely monitor oxygen saturation trends. Additionally, increased vigilance in glucose management is required, as the patient's blood glucose levels continue to fluctuate significantly. The nephrology consultation leads to the implementation of continuous renal replacement therapy (CRRT) to address the acute kidney injury and support renal function, as the patient's urine output remains critically low despite aggressive fluid resuscitation efforts.

These unfolding complications require the healthcare team to engage in complex clinical reasoning, balancing aggressive treatment of the infection with supportive care for organ systems under stress. The coordinated multidisciplinary approach aims to stabilize the patient by addressing both the source of infection and its systemic impacts, setting the stage for the next phase of management focused on recovery and prevention of further deterioration. As the team prepares for these interventions, they remain vigilant for any additional complications that may arise, maintaining a proactive stance in the patient's care continuum.

Section 4

The healthcare team diligently monitors the patient's response to the adjusted treatment plan, particularly focusing on the respiratory and renal interventions. Over the next 24 hours, the patient's response to vancomycin is carefully assessed through serial blood cultures and inflammatory markers. While the initial cultures show a slight decrease in bacterial load, indicating a positive response to the antibiotic regimen, the patient's clinical status presents mixed signals. His oxygen saturation remains variable despite increased supplemental oxygen, fluctuating between 88% and 92%, which prompts consideration of non-invasive ventilation support to mitigate further respiratory decline.

Meanwhile, the implementation of continuous renal replacement therapy (CRRT) begins to stabilize the patient's renal function. His serum creatinine level shows a modest improvement, decreasing from 3.1 mg/dL to 2.8 mg/dL, suggesting some renal recovery. However, the patient continues to exhibit signs of systemic stress, as evidenced by a persistently elevated heart rate of 110-120 beats per minute and a low-grade fever hovering around 38.5°C. The patient’s blood glucose levels remain erratic, with readings swinging between 70 mg/dL and 180 mg/dL, necessitating close monitoring and regular insulin adjustments to maintain euglycemia.

Despite these interventions, new complications arise as the patient develops signs of early delirium, characterized by confusion and fluctuating levels of consciousness. This development highlights the need for a comprehensive neurological evaluation and raises concerns about possible hypoxic brain injury or metabolic encephalopathy. The team swiftly initiates a delirium protocol, which includes optimizing the patient’s sleep-wake cycle, minimizing sedation, and ensuring adequate pain control. As the patient's journey continues, the healthcare team remains steadfast in their multidisciplinary approach, ready to adapt the treatment plan to address these evolving challenges and prevent further complications.

Section 5

The healthcare team decides to delve deeper into the patient's fluctuating oxygen saturation and increased heart rate, suspecting a potential underlying pulmonary complication. A chest X-ray and subsequent CT scan reveal the development of bilateral infiltrates, suggestive of acute respiratory distress syndrome (ARDS). This finding explains the variable oxygen saturation and prompts an immediate shift in the respiratory management strategy. The team initiates non-invasive ventilation with bilevel positive airway pressure (BiPAP) to improve oxygenation and alleviate respiratory distress. Additionally, they fine-tune the patient's fluid balance to prevent fluid overload, which could exacerbate the pulmonary condition.

Simultaneously, a neurological assessment is conducted to address the patient's early signs of delirium. A CT scan of the brain shows no acute intracranial abnormalities, ruling out major structural damage. However, the patient's Glasgow Coma Scale (GCS) score remains slightly depressed at 13, indicating the need for further supportive care to manage the delirium. The team decides to continue the delirium protocol, emphasizing environmental modifications such as reorienting the patient frequently, providing cognitive stimulation, and ensuring minimal disruption during nighttime hours to promote rest.

Laboratory results reveal a persistent mild leukocytosis, with a white blood cell count of 12,000/mm³, and continued elevation in inflammatory markers such as C-reactive protein (CRP) at 15 mg/dL. These findings suggest ongoing inflammation, possibly related to the burn injury or a secondary infectious process. The healthcare team considers expanding the antibiotic coverage to include broader-spectrum agents while awaiting further culture results. They also plan to introduce anti-inflammatory interventions, such as low-dose steroids, to help modulate the systemic inflammatory response. As the team navigates these new complications, they remain vigilant, focusing on preventing further deterioration and optimizing the patient's recovery trajectory.
