Methemoglobinemia is a potential negative side effect associated with the use of benzocaine for topical anesthesia. A healthy patient admitted for an outpatient orthopedic procedure developed the clinical symptomatology of methemoglobinemia after topicalization of the airway with benzocaine. The patient subsequently responded to appropriate treatment and was fit for discharge the same day. Methemoglobinemia should be suspected in cases where decreased pulse oximeter readings develop in patients… Expand
Methemoglobinemia after fiberoptic intubation in a patient with an unstable cervical fracture: a case report.
TLDR
Surgeons and anesthesiologists who manage multiple-injury patients with an unstable compressive-flexion injury of the cervical spine undergoing fiberoptic intubation should be aware of methemoglobinemia, a rare but potentially fatal complication related to topical airway anesthetics. Expand
Topical Anesthesia-Induced Methemoglobinemia in Bariatric Surgery Patients
TLDR
Two severely obese patients who developed methemoglobinemia following the use of topical or local anesthetic were presented and successfully treated with methylene blue IV and 100% O2 supplementation. Expand
Methemoglobinemia Secondary to Topical Benzocaine Use in a Lung Transplant Patient
TLDR
Application of the Naranjo probability scale established a highly probable relationship between topical benzocaine spray and methemoglobinemia and associated respiratory compromise, which should be administered with caution and careful monitoring in patients with preexisting disorders that compromise oxygen delivery.

The effect of clove and benzocaine versus placebo as topical anesthetics.
TLDR
Clove gel might possess a potential to replace benzocaine as a topical agent before needle insertion when applied to maxillary canine buccal mucosa of 73 adult volunteers. Expand
Methemoglobinemia in critically ill burned patients.
TLDR
This research presents a meta-anatomy of the central giant cell of the immune system, the “central giant” of the nervous system, which has been studied in unprecedented detail in detail in the context of burns. Expand

Benzocaine-induced methemoglobinemia.
TLDR
Four cases of methemoglobinemia induced by topical benzocaine use are described and pathophysiology, early diagnosis, and therapy for this reversible yet potentially fatal condition are reviewed. Expand
Methemoglobinemia Caused by Topical Benzocaine
TLDR
The use of topical benzocaine spray in a 77‐year‐old woman during endoscopic retrograde cholangiopancreatogram produced marked cyanosis and mrthemoglobin levels consistent with methemoglobinemia. Expand

TLDR
Treatment with methylene blue can be complicated by the presence of underlying enzyme deficiencies, including glucose-6-phosphate dehydrogenase deficiency and other dyshemoglobins may be confused with MHb. Expand
