Why is morphine often withheld initially in suspected strangulated obstruction with perforation?

• A. It can mask signs of peritonitis or perforation
• B. It delays imaging studies
• C. It increases intestinal motility
• D. It increases risk of dehydration

Answer: (A)

Pain signals are a crucial clue to peritoneal irritation from strangulation and possible perforation. Morphine can blunt abdominal pain and reduce reflex signs such as guarding and rebound, making it harder to detect peritonitis early. In a suspected strangulated obstruction with perforation, timely recognition and surgical intervention are essential, and masking signs with opioid analgesia can delay this. By withholding morphine initially, clinicians can rely on objective findings and imaging to guide urgent management. If analgesia is needed later, it should be given with careful reassessment, rather than before the initial evaluation.
