Which gas is used to alleviate anxiety in patients and can help relax skeletal muscles?

Nitrous oxide is a gas commonly used in dental and medical settings for its anxiolytic and muscle-relaxing properties. When administered, it can produce a state of mild sedation and euphoria, making patients feel relaxed and reducing their anxiety levels. This is particularly beneficial during dental procedures, where anxiety can hinder the patient’s ability to cooperate. Additionally, nitrous oxide helps in the reduction of skeletal muscle tension, further contributing to a more comfortable experience for patients who may be apprehensive about treatment.

In contrast, acetaminophen primarily serves as a pain reliever and does not possess anxiolytic or muscle-relaxing properties. Nonsteroidal anti-inflammatory drugs (NSAIDs) are also used for pain relief and inflammation, but they do not directly address anxiety or muscle relaxation. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose and is unrelated to anxiety or muscle relaxation. Thus, nitrous oxide stands out as the appropriate choice for alleviating anxiety and relaxing skeletal muscles.
