“…Ultrasonography also cannot be used in scenarios where there is subcutaneous air, as anatomical structures distal to the air are not visualized easily using ultrasonography. [13][14][15][16] Additionally, an ultrasonography machine is not always immediately available in an emergency scenario, and the ''boot-up'' time may be unacceptably slow. Other steps required for the use of ultrasonography (e.g., gel application, probe selection, image configuration) further delay the cricothyrotomy.…”

“…Airway ultrasound can visualize and assess the tongue, oropharynx, hypopharynx, epiglottis, larynx, vocal cords, cricothyroid membrane, cricoid cartilage, trachea, and cervical esophagus [4,35,36]. The posterior pharynx, posterior commissure, and posterior wall of the trachea cannot be visualized due to artifacts that are created by the intraluminal air column [35].…”

“…Ultrasonography has been used successfully to guide the choice of the appropriate size of endotracheal tube [4,47], tracheostomy tube [4,36], and even double-lumen tube [48,49]. Ultrasound is successfully improving the performance of airway related nerve blocks [36], including superior laryngeal nerve, deep cervical plexus, alveolar nerve, and superficial trigeminal nerve.…”

“…Ultrasound is successfully improving the performance of airway related nerve blocks [36], including superior laryngeal nerve, deep cervical plexus, alveolar nerve, and superficial trigeminal nerve. Kaur et al [50] recently published their preliminary results in ultrasound-guided superior laryngeal nerve block for upper airway anesthesia, using a hockey stickshaped 8 to 15 MHz transducer and concluded that it is a feasible approach.…”

Ultrasound is a safe, portable, relatively inexpensive, and easily accessible imaging modality, making it a useful diagnostic and monitoring tool in medicine. Anesthesiologists encounter a variety of emergent situations and may benefit from the application of such a rapid and accurate diagnostic tool in their routine practice. This paper reviews current and potential applications of ultrasound in anesthesiology in order to encourage anesthesiologists to learn and use this useful tool as an adjunct to physical examination. Ultrasound-guided peripheral nerve blockade and vascular access represent the most popular ultrasound applications in anesthesiology. Ultrasound has recently started to substitute for CT scans and fluoroscopy in many pain treatment procedures. Although the application of airway ultrasound is still limited, it has a promising future. Lung ultrasound is a well-established field in point-of-care medicine, and it could have a great impact if utilized in our ORs, as it may help in rapid and accurate diagnosis in many emergent situations. Optic nerve sheath diameter (ONSD) measurement and transcranial color coded duplex (TCCD) are relatively new neuroimaging modalities, which assess intracranial pressure and cerebral blood flow. Gastric ultrasound can be used for assessment of gastric content and diagnosis of full stomach. Focused transthoracic (TTE) and transesophageal (TEE) echocardiography facilitate the assessment of left and right ventricular function, cardiac valve abnormalities, and volume status as well as guiding cardiac resuscitation. Thus, there are multiple potential areas where ultrasound can play a significant role in guiding otherwise blind and invasive interventions, diagnosing critical conditions, and assessing for possible anatomic variations that may lead to plan modification. We suggest that ultrasound training should be part of any anesthesiology training program curriculum.

“…5 Locating the midline and correct level through careful palpation and/or ultrasound guidance and maintaining the stability of structures during puncture remain crucial components of successful needle placement for both transtracheal techniques. Competence in one technique should be directly transferable to the other; therefore, we anticipate that experience learned from transtracheal injection for airway topicalization may improve success with needle cricothyroidotomy.…”
