Bispectral Index Changes Following Boluses of Commonly Used Intravenous Medications During Volatile Anesthesia Identified From Retrospective Data.
Although patients are commonly monitored for depth of anesthesia, it is unclear to what extent administration of intravenous anesthetic medications may affect calculated bispectral (BIS) index values under general anesthesia. ⋯ Modest, but persistent changes in BIS index occurred following doses of ketamine (increase) and midazolam (decrease) during periods of stable volatile anesthetic administration.

Observational StudyMelanin-Concentrating Hormone Is Associated With Delayed Neurocognitive Recovery in Older Adult Patients With Preoperative Sleep Disorders Undergoing Spinal Anesthesia.
Aging and preoperative sleep disorders are the main risk factors affecting postoperative cognitive outcomes. However, the pathogenesis of delayed neurocognitive recovery after surgery remains ambiguous, and there is still a lack of potential biomarkers for delayed neurocognitive recovery in older adult patients with preoperative sleep disorders. Our study aimed to explore the relationship between melanin-concentrating hormone (MCH) and delayed neurocognitive recovery early after surgery in older adult patients with preoperative sleep disorders. ⋯ In older adult patients with preoperative sleep disorders, MCH is associated with the occurrence of delayed neurocognitive recovery after surgery. Preoperative testing of CSF MCH or plasma MCH may increase the likelihood of identifying the high-risk population for delayed neurocognitive recovery in older adult patients with preoperative sleep disorders.

Anesthesiology Resident Knowledge of Transfusion Medicine: Results From the Anesthesiology Transfusion Education Study.
Transfusion of blood products is a common practice in anesthesiology. Inadequate transfusion medicine knowledge may lead to inappropriate transfusion practices and patient risk. Using a validated assessment tool modified for anesthesiology, we conducted a survey of anesthesiology residents in the United States to assess transfusion medicine knowledge. ⋯ This examination highlights gaps in transfusion medicine knowledge within US anesthesiology residents. Targeted education may improve knowledge in this area and patient care.

The First Etherization in England: New Research Regarding the Identity of the First Patient, Miss Lonsdale.
On December 19, 1846, at the London home of Francis Boott, dentist James Robinson administered the vapor of diethyl ether to a young female patient named Miss Lonsdale. This was the earliest known attempt in England to provide painless operating conditions for a dental extraction, and it was successful. Many authors have since written much about Boott and Robinson, but scarcely anything is known about Miss Lonsdale. ⋯ Both subsequently emigrated to the United States where they were well-known stage performers. Accordingly, we suggest that both are highly probable candidates for that etherized patient, with the younger sister Adeline then more publicly recognizable. However, no records were found that directly associated any of the Miss Lonsdale candidates with that first dental anesthetic in England.
