New colostomy placement - Nursing Case Study

Pathophysiology

• Primary mechanism: A colostomy involves surgically diverting the colon to an opening in the abdominal wall to bypass a diseased or obstructed part of the bowel, often due to conditions like cancer, diverticulitis, or trauma. This reroutes fecal flow to an external pouch, reducing pressure and inflammation in the affected bowel segment.

• Secondary mechanism: By creating a stoma, the procedure alleviates bowel obstruction, reduces infection risk, and allows healing of damaged bowel sections. This diversion is essential for preventing complications like bowel perforation and peritonitis, supporting effective recovery.

• Key complication: Skin irritation around the stoma site is common due to exposure to digestive enzymes, necessitating diligent stoma care and monitoring for infection or necrosis to ensure patient comfort and prevent further complications.

Section 1

As the healthcare team conducts an initial assessment of the patient, they note several key findings that warrant further investigation. The swelling and redness around the stoma are more pronounced, with the peristomal skin appearing excoriated and moist, suggesting possible leakage of intestinal effluent. The stoma itself is edematous, and there is a noticeable purulent discharge, indicating a potential infection. Her elevated temperature and tachycardia further support the suspicion of an infectious process. Additionally, the patient reports increased abdominal pain that worsens with movement, contributing to her overall discomfort and distress.

Laboratory results reveal elevated white blood cell count and C-reactive protein levels, which are consistent with an inflammatory or infectious process. Blood cultures are pending, but the clinical picture raises concern for cellulitis or an abscess formation around the stoma site. The patient's blood glucose levels are also elevated, likely exacerbated by the stress of infection, necessitating more frequent monitoring and potential adjustment of her insulin regimen. Given her medical history of Type 2 Diabetes and hypertension, these complications present a complex challenge that requires careful management to prevent further deterioration.

The healthcare team collaborates to devise a comprehensive care plan, focusing on aggressive antibiotic therapy, diligent wound care, and close monitoring of the stoma and surrounding skin. They initiate broad-spectrum antibiotics empirically while awaiting culture results and consult the wound care specialist to optimize stoma management. The patient is educated about signs of worsening infection and the importance of adhering to the prescribed treatment regimen. This phase in her care journey emphasizes the need for timely intervention and meticulous attention to detail to mitigate the risk of further complications and support her recovery.

Section 2

As the patient's care progresses, the healthcare team closely monitors her response to the initiated interventions, particularly the broad-spectrum antibiotics and wound care measures. Within 48 hours, there are noticeable changes in her clinical status. The patient's temperature has decreased slightly, now hovering around 38.0°C (100.4°F), indicating a partial response to the antibiotics. However, her heart rate remains elevated at 110 beats per minute, and she continues to report significant abdominal discomfort, especially around the stoma site. The peristomal skin appears less moist, but redness and swelling persist, suggesting that while the infection is being addressed, inflammation remains a concern.

Laboratory results reveal a slight decrease in the white blood cell count to 15,000/mm³ from an initial 18,000/mm³, alongside a marginal decline in C-reactive protein levels. These improvements suggest a partial response to the treatment, yet the persistence of symptoms necessitates further investigation. The pending blood cultures return positive for Methicillin-resistant Staphylococcus aureus (MRSA), prompting a revision of the antibiotic regimen to include vancomycin, tailored to target this specific pathogen. The wound care specialist recommends continuing the current regimen while introducing an antimicrobial dressing to aid in reducing the local bacterial load.

Despite these adjustments, the patient reports new-onset nausea and decreased appetite, complicating her nutritional intake and potentially impacting her recovery. Her blood glucose levels remain unstable, with readings fluctuating between 180-250 mg/dL, necessitating further insulin adjustments and dietary consultations. These developments underscore the complexity of her condition, requiring ongoing interdisciplinary collaboration to refine her care plan. The healthcare team remains vigilant, aware that managing the delicate balance of infection control, diabetes management, and patient comfort is crucial in preventing further complications and fostering recovery.

Section 3

As the healthcare team continues to manage the patient's care, they notice a concerning change in her status. Over the next 24 hours, her heart rate stabilizes somewhat, decreasing to 100 beats per minute, but her blood pressure begins to trend downward, with readings of 90/60 mmHg. This hypotensive episode raises the suspicion of worsening sepsis, potentially exacerbated by her new MRSA diagnosis. Additionally, the patient begins to experience increased abdominal distension and tenderness upon palpation, particularly around the stoma site, suggesting possible complications such as bowel obstruction or a developing abscess.

New diagnostic results from an abdominal CT scan reveal fluid collection around the stoma site, consistent with an abscess formation, which may be contributing to her abdominal pain and distension. This finding necessitates immediate intervention, and the surgical team is consulted to evaluate the need for drainage. Alongside this, her kidney function tests indicate a rise in creatinine levels to 1.8 mg/dL from a baseline of 1.2 mg/dL, raising a concern for acute kidney injury, possibly secondary to both the infection and hypotension.

The healthcare team refines the patient’s management plan, including the initiation of intravenous fluids to address her hypotension and potential dehydration. The interdisciplinary team, including infectious disease specialists and nephrologists, collaborates to balance her fluid status with the risk of fluid overload, given her renal impairment. The patient’s nutritional status is also revisited, with adjustments in her dietary plan to accommodate her decreased appetite and ensure adequate caloric intake, crucial for her recovery. These developments highlight the need for ongoing monitoring and adaptation of her care plan to address the evolving complications and support her path to recovery.

Section 4

As the medical team implements the revised management plan, they closely monitor the patient's response to the interventions. Over the next 12 hours, the patient receives a carefully titrated regimen of intravenous fluids aimed at stabilizing her blood pressure while minimizing the risk of fluid overload. The patient's blood pressure begins to show signs of improvement, with readings stabilizing around 100/65 mmHg. However, her heart rate remains slightly elevated at 98 beats per minute, indicating that her body is still under stress. Continuous monitoring of her renal function shows that her creatinine levels have plateaued at 1.8 mg/dL, suggesting that while the acute kidney injury has not worsened, it is still a concern that requires careful management.

On reassessment, the abdominal distension and tenderness around the stoma persist, although there is no significant increase in these symptoms. The surgical team, after evaluating the CT scan and clinical findings, decides to proceed with percutaneous drainage of the abscess. The procedure is carefully coordinated with the infectious disease team to ensure that antibiotic coverage is optimized for MRSA, balancing broad-spectrum coverage with kidney-friendly options to avoid further renal compromise. Post-procedure, the patient reports a slight reduction in abdominal discomfort, though she still requires careful analgesic management to control her pain without impacting her renal function adversely.

The interdisciplinary team continues to work together, emphasizing the importance of nutrition in the patient's recovery. A dietitian is consulted to devise a meal plan that accommodates the patient's reduced appetite, focusing on nutrient-dense, easy-to-digest options that will support her caloric needs without exacerbating her gastrointestinal symptoms. With these measures in place, the team remains vigilant, recognizing that the patient's condition, while showing some improvement, is still precarious. This ongoing coordination and adaptation of care underscore the importance of a dynamic, patient-centered approach as the patient progresses through this critical phase of her recovery.

Section 5

As the patient continues her recovery, the medical team remains vigilant in their monitoring and assessment. Over the next 24 hours, there is a notable change in her clinical status. The patient begins to exhibit mild fever with a temperature of 38.3°C (100.9°F), accompanied by a mild increase in her heart rate to 104 beats per minute. Her blood pressure remains stable at 102/68 mmHg, but there is a slight decrease in her urine output, raising concerns about her renal function. The previously drained abscess site appears to be healing, with reduced tenderness, but there is increased erythema and warmth around the stoma, suggesting a potential local infection.

In response to these changes, the team orders a repeat set of laboratory tests. The results indicate a slight elevation in white blood cell count to 13,500/mm³, with an increased neutrophil percentage, suggesting an inflammatory or infectious process. C-reactive protein (CRP) levels also show a mild increase, reinforcing the suspicion of an ongoing inflammatory response. Blood cultures are drawn to rule out any systemic infection, and the wound site is cultured to identify any pathogens present. The team revises the antibiotic regimen to ensure comprehensive coverage while maintaining kidney-friendly options, and they emphasize the importance of maintaining fluid balance to support renal function.

These developments prompt the interdisciplinary team to reassess their management plan, focusing on the potential for localized infection and the risk of sepsis. They prioritize optimizing the patient's immune response and ensuring adequate nutritional support to bolster her reserves. As they await further diagnostic results, the team remains committed to close monitoring, ready to adjust the treatment plan as needed. The patient's journey through this complex recovery phase highlights the necessity of a coordinated, responsive approach to care, with an emphasis on anticipating and addressing complications as they arise.
