Point-of-care ultrasound imaging is increasingly used by anesthesiologists to facilitate rapid clinical diagnosis and treatment in the perioperative period. With its growing popularity, inevitably, unfamiliar structures will be observed. ⋯ We address the clinical, ethical, and legal implications of incidental findings in anesthesiology. We offer recommendations and an algorithmic approach to these occurrences.

Ketamine is an important component of multimodal treatment and a commonly used anesthetic drug. However, its analgesic effects have not been fully assessed intraoperatively because of difficulties in measuring this effect. ⋯ With increasing doses of ketamine, the pupillary light reflex and the pupillary dilation response decreased. This could be caused by N-methyl-D-aspartate receptor antagonism in the pupillary reflexes pathway or by the analgesic effects of ketamine.

We report the unexpected transesophageal echocardiography (TEE) finding of a left atrial (LA) thrombus near the end of cardiopulmonary bypass and after deployment of an AtriClip (Atricure, Inc, Westchester, OH) in an 84-year-old man with atrial fibrillation and aortic stenosis undergoing aortic valve replacement and LA appendage ligation. TEE examination before cardiopulmonary bypass and deployment of the AtriClip had not shown a thrombus in the LA appendage. The heart was rearrested and thrombus was successfully removed through a left atriotomy. This case emphasizes the importance of careful TEE examination for dislodged thrombi after surgical manipulation of the LA appendage.

Case Reports
Laryngeal Mask Airway Embedded With Pharyngeal Suction Catheters for Rhinoplasty: A Case Report.
A flexible laryngeal mask airway device (LMAD) embedded with 2 pharyngeal suction catheters was used for a young female patient who underwent a revision rhinoplasty, septoplasty, and chin implant. The modified LMAD was constructed by attaching 2 suction catheters onto the back of the mask; it functioned well without signs of malfunction or complications, with a total of 71 mL of blood evacuated from the pharyngeal area during the five and a half hour surgery. The patient emerged from anesthesia without coughing or straining, and reported no sore throat or nausea/vomiting in the recovery room.
