The authors, editors, and publisher have exerted every effort to ensure that drug selections and dosages set forth in this text are in accordance with current recommendations and practice at the time of publication.

Some drugs and medical devices presented in this publication have clearance from the US Food and Drug Administration for limited use in restricted research settings. It is the responsibility of the health-care provider to ascertain the clearance status of each drug or device planned for use in their clinical practice.
