Summary
Topical anesthetic lidocaine with epinephrine significantly reduces patient discomfort during flexible nasofibrolaryngoscopy. This combination is recommended for improved patient experience in otolaryngology procedures.
Area of Science:
- Otolaryngology
- Anesthesiology
Background:
- Flexible nasofibrolaryngoscopy is a crucial diagnostic tool in otolaryngology.
- Patient discomfort during the procedure necessitates effective topical anesthesia.
Purpose of the Study:
- To compare the efficacy of lidocaine with epinephrine, oxymetazoline, and placebo for topical anesthesia during flexible nasofibrolaryngoscopy.
- To assess patient-reported discomfort using a visual analogue scale.
Main Methods:
- Prospective, double-blind, crossover study involving 18 patients without prior nasal disease.
- Comparison of lidocaine-epinephrine, oxymetazoline, and placebo nasal sprays.
- Discomfort assessment via visual analogue scale during nasofibrolaryngoscopy.
Main Results:
- Lidocaine-epinephrine resulted in the lowest mean discomfort score (1.94), followed by oxymetazoline (3.78) and placebo (4.61).
- Lidocaine-epinephrine showed statistically significant reductions in discomfort compared to both oxymetazoline (P<0.05) and placebo (P<0.05).
Conclusions:
- Lidocaine with epinephrine is an effective topical anesthetic for reducing pain and discomfort during flexible nasofibrolaryngoscopy.
- The study recommends the use of topical nasal anesthesia, specifically lidocaine-epinephrine, for this procedure.

Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

01:20Inhalational Anesthetics: Overview
1.7K
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
2.0K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
