True or False: N2O should not be used with bowel obstructions but is acceptable with ulcers.

Nitrous oxide (N2O) is a gas commonly used for its analgesic and anesthetic properties, but its use is contraindicated in certain medical conditions. In the case of bowel obstructions, the presence of N2O poses significant risks because it can diffuse into the bowel, leading to increased intestinal gas and potentially exacerbating the obstruction. This could result in increased distension, pain, or perforation of the bowel, which is why its use is strictly avoided in such scenarios.

When considering the use of N2O with ulcers, it is crucial to note that ulcers, particularly peptic ulcers, are generally not directly impacted by the use of N2O. N2O does not interact negatively with ulceration in the way it does with bowel obstructions. Thus, using N2O in patients with ulcers is typically deemed safe as long as there are no other contraindications present.

Therefore, the statement that N2O should not be used with bowel obstructions but is acceptable with ulcers is accurate, confirming that the answer is true.
