Background: YouTube™ ("YouTube") is often used as an educational tool to instruct anesthesia providers on regional anesthesia nerve blocks. However, there is no current objective standard to assess the educational quality of these user-uploaded videos. A new approach was used to objectively validate these videos by comparing them to high quality educational sources for the seven most commonly used nerve blocks. Objective: We sought to evaluate the educational quality of user-uploaded videos when compared to the highest quality anesthesia society websites (NYSORA, ACEP, USRA). Methods: After reviewing the instructional material available for the seven most frequently conducted nerve blocks on high-quality reference websites, we documented the educational characteristics present including such things as indications, volume, anatomy, etc. Next we reviewed the five most popular videos on YouTube for each block (by views) and documented the presence or absence of these educational characteristics. Results: Eighteen educational characteristics were documented in the "high-quality" anesthesia society reference material. Correlation was sought between this material and YouTube videos. Although there were varying degrees of correlation between the high quality sources and the videos, rarely did YouTube videos contain as high a percentage of these educational characteristics as the well-established sources. Some videos contained very few of these important educational characteristics. Conclusion: Although YouTube has been used an educational tool, we recommend that only high quality sources be used to teach or illustrate regional anesthesia nerve blocks.

Unlike the traditional Laplace transform, the Sumudu transform of a function, when approximated as a power series, may be readily inverted using factorial-based coefficient diminution. This technique offers straightforward computational advantages for approximate range-limited numerical solutions of certain ordinary, mixed, and partial linear differential and integro-differential equations. Furthermore, discrete convolution (the Cauchy product), may also be utilized to assist in this approximate inversion method of the Sumudu transform. Illustrative examples are provided which elucidate both the applicability and limitations of this method.

Objective We sought to evaluate the educational quality of user-uploaded videos when compared to the highest quality anesthesia society websites (NYSORA, ACEP, USRA) Methods We first catalogued the characteristics of the instructional material on three of the highest quality anesthesia society websites (NYSORA, ACEP, USRA) into 18 different items. Next, we surveyed the five most popular anesthesia block videos on YouTube for each of the seven peripheral nerve blocks in question. The presence or absence of each category was recorded. Results Although there were varying degrees of correlation between the high quality sources and the videos, rarely did YouTube videos contain as high a percentage of these educational characteristics as the well-established sources. Some videos contained very few of these important educational characteristics. Conclusion Although YouTube has been used an educational tool, we recommend that only high quality sources be used to teach or illustrate regional anesthesia nerve blocks.
