`Tested using Claude 3.5 Sonnet` **user: Testing LLM's simple logic: 9.11 and 9.8, which is bigger?** **ai**: 9.11 is bigger than 9.8. This is because when comparing decimal numbers, we can look at them digit by digit from left to right. Both numbers start with 9, but in the tenths place (first decimal place), 1 is greater than 8, making 9.11 the larger number. [Timestamp: 2025/01/23 12:09:39] --- **user: Reviewing the note on [[Wound Healing]], what are key points a surgeon should understand?** **ai**: Based on the note, here are the 3 most critical points a surgeon should understand about wound healing: 1. Oxygen Delivery and Infection Prevention - These are the two most common causes of poor wound healing - Good oxygen delivery requires adequate cardiac output, perfusion, and RBCs - Infection can reduce oxygen tension, lower pH, and increase inflammation - Biofilms are particularly problematic as they evade typical treatment 2. Tensile Strength Timeline - Day 4-5: Initial strength develops - Week 3: 30% of final strength - Month 3: 80% of final strength - Important: Healed tissue never reaches 100% of original strength - This timeline should guide post-operative activity restrictions and suture selection 3. Technical Finesse - Achieve meticulous hemostasis while avoiding excess thermal injury - Never close inflamed tissue primarily - Use enough sutures to control tension without compromising blood supply - Minimize crush injury through gentle tissue handling - Manage edema effectively to optimize healing These points directly impact surgical decision-making and outcomes.

The deeper fat layer is: - Less dense in nature - Has blood supply from the subdermal plexus and myocutaneous perforators - Easier to thin without compromising the skin 2. The superficial fat layer (Camper's fascia) should be preserved because it: - Is more dense and durable - Has greater blood supply from the skin - Helps maintain skin quality and contour This anatomical understanding explains why the deeper fat layer is a safer target for liposuction, as it allows for fat removal while maintaining adequate blood supply to the skin and preserving the more structurally important superficial layer. [Timestamp: 2025/01/23 12:14:52] > **Cuong's comment**: The last answer intrigues me because it would also be a connection I draw reading about the anatomy. This shows promises in using an LLM ai model grounded in a surgical knowledge base to potentially draw on anatomical and pathophysiological info to offer tips on surgical techniques. HOWEVER, the answer offerred aligns only with 50% of actual surgery: > > *One must appreciate that while the superficial layer is often targeted, it is also the one most prone to liposuction-related complications, namely contour irregularities or vascular compromise to the overlying tissue. These complications can be avoided by limiting aggressive superficial liposuction and ensuring cannula ports are not directly engaged with the overlying skin.* ^[Bartow MJ, Raggio BS. Liposuction.

Also, all answers are grounded to data in this site; greater utility may be seen if I figure a way to link it to pubmed's database of articles. #experimental
