I particularly like the "cited by" feature, which provides links to other papers that have cited the original (at least the ones in Scholar's database). This type of citation analysis is an innovative variation of PubMed's invaluable "related articles" feature.
Sample Searches. Got to http://scholar.google.com and enter:
Ex. 1. Heddle transfusion
Ex. 2. predictive value transfusion
Ex. 3. root cause analysis transfusion
