**Core Concept**
During laparoscopy, the pressure in the abdomen of children is carefully controlled to prevent complications such as bleeding, organ injury, and respiratory compromise. The ideal pressure is crucial to maintain a safe and effective procedure.

**Why the Correct Answer is Right**
The correct pressure is usually between 8-12 mmHg, which is lower than the pressure used in adults. This lower pressure helps to minimize the risk of complications in children, who have a smaller abdominal cavity and more delicate tissues. The pressure is also titrated to maintain a clear visual field and prevent the spread of gas to other areas of the body.

**Why Each Wrong Option is Incorrect**
**Option A:** Using a pressure above 15 mmHg can lead to increased risk of bleeding and organ injury due to the increased pressure on the blood vessels and tissues.
**Option B:** Using a pressure below 5 mmHg may not provide an adequate visual field, making it difficult for the surgeon to perform the procedure safely and effectively.
**Option C:** Using a pressure of 20 mmHg or higher is not typically used in pediatric laparoscopy, as it increases the risk of complications and may not provide additional benefits.

**Clinical Pearl / High-Yield Fact**
In pediatric laparoscopy, the pressure should be carefully titrated to maintain a safe and effective procedure, and the surgeon should be prepared to adjust the pressure as needed to prevent complications.

**Correct Answer: C. 20 mmHg or higher is not typically used in pediatric laparoscopy.**
