From the Guidelines
Patients with small bowel obstruction (SBO) typically need IV fluids as part of their initial management. IV fluid resuscitation is essential to correct fluid and electrolyte imbalances caused by vomiting, decreased oral intake, and third-spacing of fluids into the bowel wall and lumen. According to a narrative review published in the World Journal of Emergency Surgery in 2019 1, supportive treatment must begin as soon as possible with intravenous crystalloids, anti-emetics, and bowel rest.
- The recommended IV fluids include isotonic dextrose-saline crystalloid and balanced isotonic crystalloid replacement fluids containing supplemental potassium in an equivalent volume to the patient’s losses.
- A Foley catheter should be inserted to monitor urine output, which is crucial in assessing the patient's hydration status and renal perfusion.
- Nasogastric suction can be diagnostically useful to analyze gastric contents and therapeutically important to prevent aspiration pneumonia and decompress the proximal bowel.
- Fluid requirements should be reassessed frequently using vital signs, urine output, and laboratory values to ensure optimal fluid and electrolyte balance.
- IV fluid therapy continues until the obstruction resolves and the patient can tolerate adequate oral intake, helping to maintain intravascular volume, support organ perfusion, and create optimal conditions for potential spontaneous resolution of the obstruction or preparation for surgical intervention if needed.
From the Research
Management of Small Bowel Obstruction
- The management of small bowel obstruction (SBO) typically includes intravenous fluid resuscitation, analgesia, and determining the need for operative vs. nonoperative therapy 2, 3.
- Intravenous hydration is a crucial component of medical resuscitation in SBO patients, aiming to correct fluid and electrolyte imbalances 3.
- The use of intravenous fluids helps to prevent dehydration and support the patient's overall condition, especially in cases where oral intake is not possible due to vomiting or bowel obstruction 4, 5.
Importance of Intravenous Fluids
- Intravenous fluids are essential in the initial management of SBO, as they help to stabilize the patient and prepare them for potential surgery 2, 6.
- The administration of intravenous fluids, along with other supportive measures, can help to reduce the risk of complications and improve patient outcomes 3, 5.
- The choice of intravenous fluids and the rate of administration may vary depending on the individual patient's needs and the severity of the obstruction 4, 6.
Overall Approach to SBO Management
- The management of SBO requires a multidisciplinary approach, involving emergency medicine physicians, surgeons, and other healthcare professionals 2, 5.
- A systematic and evidence-based approach to SBO management can help to improve patient outcomes and reduce the risk of complications 3, 6.
- The use of protocols and guidelines, such as those outlined in the studies, can help to standardize care and ensure that patients receive the most effective treatment for their condition 4, 5.
