diverticulitis - Nursing Case Study

Pathophysiology

• Primary mechanism: Diverticulitis primarily occurs when diverticula, small pouches in the intestinal wall, become inflamed or infected due to fecal matter obstruction. This obstruction leads to increased intraluminal pressure, compromising blood supply and triggering inflammation.

• Secondary mechanism: Bacterial overgrowth and invasion of the diverticular wall occur as the stagnant fecal material offers a breeding ground for bacteria. This results in further inflammation and can lead to microperforation of the diverticular wall.

• Key complication: If untreated, diverticulitis can progress to complications such as abscess formation, perforation, or peritonitis, which are significant risks for systemic infection and require prompt medical intervention.

Section 1

New Diagnostic Results:

Following the initial assessment, the healthcare team ordered a complete blood count (CBC), a comprehensive metabolic panel (CMP), and a CT scan of the abdomen to further evaluate the patient's condition. The CBC revealed leukocytosis with a white blood cell count of 15,000/µL, indicating an active inflammatory process likely due to the diverticulitis. The CMP showed mild hyponatremia with a sodium level of 134 mmol/L and an elevated C-reactive protein (CRP) level, both suggestive of an ongoing acute inflammatory response. The CT scan of the abdomen confirmed the presence of diverticulitis with evidence of localized thickening of the sigmoid colon and pericolic fat stranding, suggestive of inflammation. Notably, the scan also identified a 3 cm pericolic abscess adjacent to the inflamed diverticular area.

These findings necessitate a shift in the management plan to address the abscess, which poses a risk for further complications such as rupture or generalized peritonitis. The presence of an abscess indicates that the infection has progressed beyond uncomplicated diverticulitis, requiring more aggressive intervention. This information supports the consideration of percutaneous drainage of the abscess under radiological guidance or surgical consultation if drainage is not feasible or if the patient's condition deteriorates. Additionally, the patient will require broad-spectrum intravenous antibiotics to cover both anaerobic and aerobic organisms, given her allergy to penicillin. The healthcare team must monitor her vital signs closely, especially looking for signs of sepsis such as worsening tachycardia, hypotension, or increased respiratory rate, as well as reassess her pain and abdominal tenderness to evaluate the effectiveness of the treatment and detect any signs of further complications.

Section 2

Change in Patient Status:

Despite the initiation of broad-spectrum intravenous antibiotics and supportive care, the patient's condition has shown signs of deterioration over the past 24 hours. Her vital signs now reveal a low-grade fever of 100.8°F (38.2°C), tachycardia with a heart rate of 110 beats per minute, and a blood pressure reading that has dropped to 98/60 mmHg, indicating a possible hemodynamic instability. Her respiratory rate has increased to 22 breaths per minute, and she reports worsening abdominal pain, rated at 8 out of 10, with increased tenderness on palpation, especially in the left lower quadrant. Additionally, the patient has developed mild confusion and difficulty concentrating, raising concerns about potential early sepsis or electrolyte imbalance, particularly considering her prior hyponatremia.

Given these developments, the healthcare team is prompted to reassess the current management plan. The patient's confusion and altered vital signs necessitate a review of her fluid and electrolyte status, as well as a reassessment of the adequacy of antibiotic coverage. Repeat laboratory tests, including a complete blood count and a comprehensive metabolic panel, are ordered to evaluate for any further drop in sodium levels or other electrolyte disturbances. Blood cultures are also obtained to identify any bacteremia that may be contributing to her clinical decline. The team considers the possibility of escalating the level of care, including the potential need for ICU monitoring, should the patient's condition continue to worsen. Additionally, urgent consultation with the surgical team is requested to evaluate the feasibility of percutaneous abscess drainage or surgical intervention, given the increased risk of sepsis due to the unresolved abscess. The patient's status underscores the importance of vigilant monitoring and timely intervention to prevent further complications.

Section 3

New Diagnostic Results:

The repeat laboratory tests reveal several critical changes that provide insight into the patient's deteriorating condition. The complete blood count shows a white blood cell count of 17,000/mm³, indicating a worsening leukocytosis, which is suggestive of an ongoing infectious process. The comprehensive metabolic panel highlights a further drop in serum sodium levels to 128 mmol/L, confirming worsening hyponatremia. Additionally, the serum lactate level is elevated at 3.5 mmol/L, supporting the clinical suspicion of early sepsis. Blood cultures remain pending, but the elevated lactate and leukocytosis heighten the concern for systemic infection.

Abdominal imaging, including a CT scan, indicates an increase in the size of the previously identified diverticular abscess. The scan also reveals evidence of microperforation, which has likely contributed to the patient's escalating symptoms and systemic response. This imaging result aligns with her increased abdominal pain and tenderness, particularly in the left lower quadrant.

Given these findings, the healthcare team determines an urgent need to adjust the management plan. The priority is to address the potential source of infection by consulting with the surgical team to discuss options for abscess drainage or surgical intervention. The patient's fluid status is also reassessed, and a cautious approach to correcting the hyponatremia is initiated, mindful of the risks of rapid correction. The broad-spectrum antibiotics are reviewed and optimized, pending culture results, to ensure sufficient coverage. The patient's overall condition prompts the team to escalate her level of care to the ICU for closer monitoring of her hemodynamic status and to manage the risk of sepsis progression. These interventions are critical to stabilize the patient and prevent further complications.

Section 4

As the patient is transferred to the Intensive Care Unit (ICU), the healthcare team conducts a thorough initial assessment to evaluate her current status and prioritize interventions. Her vital signs reveal a heart rate of 112 beats per minute, respiratory rate of 24 breaths per minute, blood pressure of 92/58 mmHg, and an oxygen saturation of 93% on room air. The elevated heart rate and respiratory rate, combined with hypotension, suggest a compensatory response to the reduced perfusion associated with sepsis. Upon physical examination, she is diaphoretic and exhibits increased abdominal distension with pronounced guarding and rebound tenderness in the left lower quadrant, consistent with worsening inflammation and possible peritonitis.

In light of the new critical findings, the medical team initiates an aggressive fluid resuscitation protocol using isotonic saline to address her hypotensive state and support organ perfusion. Continuous monitoring of her fluid balance and electrolyte levels is emphasized, particularly given her pre-existing hyponatremia. The decision is made to adjust her antibiotic regimen to include medications with enhanced anaerobic and aerobic bacterial coverage, while awaiting further blood culture results to tailor therapy more precisely. The surgical team is promptly consulted to evaluate the potential need for percutaneous drainage of the abscess or exploratory laparotomy, considering the risk of further septic deterioration due to the microperforation.

Despite these interventions, the patient's condition remains tenuous, and she begins to exhibit signs of altered mental status, such as confusion and disorientation, raising concerns about possible septic encephalopathy. Continuous monitoring of her neurological status and vital signs becomes a priority, with plans for repeat imaging and reassessment of her abdominal status as her clinical picture evolves. These developments underscore the critical need for interdisciplinary collaboration and prompt decision-making to manage her complex condition effectively.

Section 5

As the medical team closely monitors the patient's response to the initial interventions, a repeat CT scan of the abdomen and pelvis is performed to reassess the extent of her diverticulitis and evaluate for any new developments. The imaging reveals an increase in the size of the previously identified abscess, now measuring 5 cm in diameter, with evidence of a contained microperforation. The findings suggest a worsening of her condition and necessitate immediate reevaluation of her management plan. Additionally, the blood cultures return positive for Escherichia coli, confirming the presence of a Gram-negative bacterial infection, which guides further refinement of her antibiotic regimen.

Despite ongoing fluid resuscitation, the patient's blood pressure remains borderline, hovering around 94/60 mmHg, and her heart rate continues to be elevated at 110 beats per minute, indicating persistent hemodynamic instability. Her laboratory results show a rising white blood cell count of 18,000/µL, alongside an elevated lactate level of 3.5 mmol/L, both suggestive of ongoing systemic infection and inadequate tissue perfusion. Her electrolytes reveal persistent hyponatremia, with a sodium level of 130 mEq/L, necessitating careful management to avoid exacerbating her neurological symptoms.

In light of these developments, the surgical team is consulted once again, and the decision is made to proceed with percutaneous drainage of the abscess, aiming to control the source of infection and mitigate further septic complications. The collaborative approach ensures that all potential avenues are explored to stabilize the patient. Throughout this process, the healthcare team remains vigilant in monitoring her response to these interventions, ready to adapt the treatment plan as necessary, based on her evolving clinical status and any new complications that may arise.
