Summary
Nitrous oxide (N2O) inhalation did not significantly reduce discomfort during nasal local anesthesia. Further research is needed to determine if longer N2O inhalation times benefit nasal surgery pain management.
Area of Science:
- Anesthesiology
- Otolaryngology
Background:
- Nitrous oxide (N2O) is known to reduce discomfort in various medical procedures.
- Assessing its efficacy in conjunction with local anesthesia for nasal operations is important for patient comfort.
Purpose of the Study:
- To evaluate the effectiveness of nitrous oxide (N2O) inhalation prior to local anesthesia administration in outpatient nasal surgery.
- To determine if N2O provides a clinical benefit in reducing patient discomfort during nasal procedures.
Main Methods:
- A prospective, randomized, single-blinded, placebo-controlled study involving 90 patients.
- Patients were divided into three groups: N2O/O2 inhalation, room air inhalation, or local anesthesia only.
- Pain and discomfort were assessed using a visual analog scale.
Main Results:
- Nitrous oxide (N2O) inhalation was well-tolerated and easy to administer.
- No significant additional benefit was observed in reducing pain or discomfort when N2O was used before local nasal anesthesia.
Conclusions:
- In this study, nitrous oxide (N2O) did not demonstrate a clinical benefit for discomfort during local anesthesia for nasal operations.
- Additional studies with extended inhalation durations are recommended to fully understand N2O's role in nasal surgery anesthesia.

01:20Inhalational Anesthetics: Overview
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...
01:23Local Anesthetics: Common Agents and Their Applications
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...

01:30Local Anesthetics: Chemistry and Structure-Activity Relationship
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...
01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
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...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:29Administering Oxygen by Nasal Cannula
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
