Adequate surgical view during various types of nasal procedures is essential for surgical operations to be performed in a safe, efficient, and successful manner. Minimizing bleeding during surgery is an important way of increasing visualization that is commonly achieved by using a vasoconstrictive agent to control intraoperative hemorrhage. Many otolaryngologists choose to employ topical cocaine to minimize bleeding during surgery owing to its vasoconstrictive properties, while simultaneously benefitting from its dual local anesthetic effects. The relative benefit of topical cocaine for otolaryngologic procedures when compared to other topical analgesics and vasoconstrictors remains a topic of discussion due to the multiple potential cardiac and central nervous system side effects associated with cocaine administration. Furthermore, there is not a scientifically backed maximal safe dose published; instead, most of the guidelines for intranasal cocaine use are based on untested clinical practice. Despite this, the short latency, adequate duration of action, and inherent vasoconstrictive and decongestive capabilities make cocaine a valuable anesthetic agent for use in clinical procedures. As the relative benefit of using topical cocaine compared to the use of other vasoconstrictors and analgesics for nasal procedures remains undetermined in the current literature, this leaves the need for a comprehensive review of research that explores the risks and benefits of using topical cocaine in nasal procedures based on clinical trials that compare intranasal cocaine with various other analgesics and vasoconstrictors.
