**Core Concept**
Laparoscopy involves insufflating the abdominal cavity with carbon dioxide to create a working space for surgical procedures. In pediatric patients, the optimal intra-abdominal pressure for laparoscopy is crucial to prevent complications while ensuring adequate visualization.

**Why the Correct Answer is Right**
The recommended intra-abdominal pressure for laparoscopy in children ranges between 8-12 mm Hg. This lower pressure is essential to avoid potential complications such as decreased venous return, increased intra-cardiac pressure, and respiratory compromise. In pediatric patients, higher pressures may lead to these adverse effects due to their smaller body size and relatively underdeveloped cardiovascular system. The optimal pressure range helps maintain a balance between providing a sufficient working space and minimizing the risk of complications.

**Why Each Wrong Option is Incorrect**
**Option A:** 2-6 mm Hg is too low to provide an adequate working space for laparoscopic procedures.
**Option C:** 14 - 18 mm Hg is higher than the recommended range and may lead to increased risk of complications in pediatric patients.
**Option D:** 20 - 24 mm Hg is excessively high and may cause significant hemodynamic instability, respiratory distress, and other complications in children.

**Clinical Pearl / High-Yield Fact**
When performing laparoscopy in pediatric patients, it's essential to remember that lower intra-abdominal pressures are generally recommended to minimize the risk of complications. A safe starting point is to use the lowest effective pressure, and titrate as needed to ensure adequate visualization and working space.

✓ Correct Answer: B. 8-12 mm Hg
