People often recommend chewing gum during ascent/descent in aircraft because chewing gum increases the rate of salivation, and swallowing the excess saliva opens the Eustachian tubes. In a clinical setting, the Valsalva maneuver is commonly done against a closed glottis or an external pressure measuring device, thus eliminating or minimizing ...
Inferior alveolar nerve block or IANB - The nerve is approached from the opposite side of the mouth over the contralateral premolars. After piercing the mandibular tissue on the medial border of the mandibular ramus within the pterygomandibular space and then contacting medial surface of the alveolar bone as well as being lateral to the ...
Shisa are wards, believed to protect from some evils. People place pairs of shisa on their rooftops or flanking the gates to their houses, with the left shisa traditionally having a closed mouth, the right one an open mouth. [1] The open mouth shisa traditionally wards off evil spirits, and the closed mouth shisa keeps good spirits in.
A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent (open and unobstructed) airway. Tracheal tubes are frequently used for airway management in the settings of general anesthesia, critical care, mechanical ventilation, and emergency medicine. Many different types of ...
Local anesthetic injections are given in specific areas of the mouth, rather than the whole body. Although several different medications are available, the most commonly used local anesthetic to prevent pain in the area around a tooth is lidocaine (also called xylocaine or lignocaine). Lidocaine's half-life in the body is about 1.5–2 hours. [2]
Hypersalivation can contribute to drooling if there is an inability to keep the mouth closed or difficulty in swallowing (dysphagia) the excess saliva, which can lead to excessive spitting. Hypersalivation also often precedes emesis (vomiting), where it accompanies nausea (a feeling of needing to vomit).
In most cases, the chest tube related pain goes away after the chest tube is removed, however, chronic pain related to chest tube induced scarring of the intercostal space is not uncommon. [citation needed] Subcutaneous emphysema indicates backpressure created by undrained air, often caused by a clogged chest tube or insufficient negative pressure.
A silastic tube or stent may be employed along with probing to maintain tear duct patency. [6] A systematic review comparing immediate probing with deferred probing found that in children with unilateral nasolacrimal duct obstruction, immediate probing resulted in a higher success rate of treatment compared to deferred probing.
