This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Sutures and Anastomoses, Subject name: Surgery
Which of the following is most ideal when sealing a vessel? 
Select and explain. 
A. Continuous low-voltage waveforms, B. Continuous high-voltage waveforms, C. Intermittent low-voltage waveforms, D. Intermittent high-voltage waveforms
A: Continuous low-voltage waveforms
Answer: A: Continuous low-voltage waveforms 
Explanation: Use of a continuous low-voltage waveform is the most effective means of sealing a blood vessel. Continuous low- voltage wavelengths apply a consistent amount of energy, which causes dessication and protein denaturation without vaporization. Incomparison high voltage waveform will generate more heat leading to to increased thermal spread thus may lead to collateral tissue damage
