Methemoglobinemia Induced By Topical Anesthesia During Fiberoptic Endotracheal Intubation, Matthew C. Miller, Michael T. Gaslin, Kathleen Herb, David Rosen

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Poster presentation at 2005 American Academy Of Otolaryngology Head and Neck Surgery Annual Meeting, Los Angeles, CA September 25-28, 2005.

Introduction: Although local anesthetics are usually well tolerated, otolaryngologists need to be aware of the sometimes serious adverse events they can cause. The benzocaine containing sprays Hurricaine and Cetacaine are occasionally associated with the onset of life-threatening methemoglobinemia. The specific treatment for this condition is methylene blue.

Methods and Measures: We describe a case report of a 48 year old female who developed a methemoglobin level of 41% after receiving topical benzocaine to her oropharynx. We discuss the case in …

Unilateral Olfactory Thresholds In A Chemosensory Clinic Population, Beverly Cowart, Edmund Pribitkin, David Rosen, Christopher Klock, Timothy Laflam

Poster presentation at 26th Annual Meeting of the Association of Chemoreception Sciences in Sarasota Florida, April 21-25, 2004.

INTRODUCTION

Because there is the possibility of unilateral loss of olfactory function or differential degrees of olfactory dysfunction in the two nostrils, unilateral tests of olfactory threshold sensitivity are routinely included in many chemosensory clinical test batteries to supplement bilateral tests (e.g., Cain et al., 1988; Hummel et al., 1997). Surprisingly, however, the results of unilateral testing in patients with chemosensory complaints have not been extensively reported. Thus, it is unclear how useful these additional measures are in characterizing individual patients.
