Ketamine in Critically Ill Patients: Use, Perceptions, and Potential Barriers.

Objective: To evaluate practitioner use of ketamine and identify potential barriers to use in acutely and critically ill patients. To compare characteristics, beliefs, and practices of ketamine frequent users and non-users. Methods: An online survey developed by members of the Society of Critical Care Medicine (SCCM) Clinical Pharmacy and Pharmacology Section was distributed to physician, pharmacist, nurse practitioner, physician assistant and nurse members of SCCM. The online survey queried SCCM members on self-reported practices regarding ketamine use and potential barriers in acute and critically ill patients. Results: Respondents, 341 analyzed, were mostly adult physicians, practicing in the United States at academic medical centers. Clinicians were comfortable or very comfortable using ketamine to facilitate intubation (80.0%), for analgesia (77.9%), procedural sedation (79.4%), continuous ICU sedation (65.8%), dressing changes (62.4%), or for asthma exacerbation and status epilepticus (58.8% and 40.4%). Clinicians were least comfortable with ketamine use for alcohol withdrawal and opioid detoxification (24.7% and 23.2%). Most respondents reported "never" or "infrequently" using ketamine preferentially for continuous IV analgesia (55.6%) or sedation (61%). Responses were mixed across dosing ranges and duration. The most common barriers to ketamine use were adverse effects (42.6%), other practitioners not routinely using the medication (41.5%), lack of evidence (33.5%), lack of familiarity (33.1%), and hospital/institutional policy guiding the indication for use (32.3%). Conclusion: Although most critical care practitioners report feeling comfortable using ketamine, there are many inconsistencies in practice regarding dose, duration, and reasons to avoid or limit ketamine use. Further educational tools may be targeted at practitioners to improve appropriate ketamine use.

Asymptomatic Severe Aortic Stenosis and Noncardiac Surgery.

The patient with severe asymptomatic aortic stenosis presenting for elective noncardiac surgery poses a unique challenge. These patients are not traditionally offered surgical aortic valve replacement or transcatheter aortic valve replacement given their lack of symptoms; however, they are at increased risk for postsurgical complications given the severity of their aortic stenosis. The decision to proceed with elective noncardiac surgery should be based on individual and surgical risk factors. However, severity of aortic stenosis is not accounted for in current surgical risk factor assessment scoring; therefore, extensive communication with patients and surgical teams is necessary to minimize a patient's risk. A clear intraoperative plan should be designed to manage the unique hemodynamics of these patients, and a discussion should address postoperative placement.

Retrospective Evaluation of the Perioperative Management of Patients Undergoing Total Pancreatectomy With Islet Autotransplantation: Single Institution Review.

OBJECTIVE: The aim of this retrospective descriptive study was to examine associations with the perioperative management of patients undergoing total pancreatectomy with islet autotransplantation, which may impact complication rate and hospital length of stay. METHODS: We retrospectively collected data on 165 patients, and 161 patients were included in the final analysis. Data collected included preoperative, intraoperative, and postoperative patient and procedural characteristics. RESULTS: Approximately 46.6% of patients experienced 1 or more complications. The occurrence of complications was associated with postoperative day 1 hemoglobin levels, use of intraoperative goal-directed therapy, estimated intraoperative blood loss, and total amount of intraoperative insulin given. Hospital length of stay was significantly associated with number of complications, use of goal-directed therapy, procedure duration, and postoperative day 1 hemoglobin levels. CONCLUSIONS: Overall, our retrospective descriptive study adds to the emerging body of literature determining optimal perioperative management of patients undergoing total pancreatectomy with islet autotransplantation.
