Abstract

Background:

Pneumatosis intestinalis (PI), infiltration of gas into the bowel wall, has traditionally been associated with immediate operative intervention and a high mortality rate.

Methods:

We retrospectively reviewed the diagnosis and management of pneumatosis in an attempt to characterize the disease, and examined management strategies.

Results:

Ninety-seven patients had a computed tomography (CT) diagnosis of pneumatosis. The location of pneumatosis was as follows: 46% colon, 27% small bowel, 5% stomach, and 7% both small and large bowel. Fourteen patients also had portal venous gas and 6 (43%) of these patients died. Management strategy was non-operative in 52%, operative in 33%, and futile care in 15%. The overall mortality rate was 22% (16% operative, 6% non-operative, and 87% futile). Patients who died had a higher mean APACHE II score (25 vs 11, P <.001).

Conclusions:

Approximately 50% of patients with pneumatosis can be successfully managed non-operatively. The combination of PI and portal venous gas may confer a higher mortality rate.

Inflammatory Bowel Disease V: Surgical Management

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Pneumonia V: Nursing management and Prevention

Pneumonia V: Nursing management and Prevention

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.

Intestinal Obstruction II: Pathophysiology

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Pneumothorax-II

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
Clinical Manifestations:

Pneumonia IV: Management

Pneumonia IV: Management

The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
