Evaluating Patient-Centered Outcomes in Clinical Trials of Procedural Sedation, Part 2 Safety: Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research Recommendations.
The Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research, established by the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks, a public-private partnership with the US Food and Drug Administration, convened a second meeting of sedation experts from a variety of clinical specialties and research backgrounds to develop recommendations for procedural sedation research. The previous meeting addressed efficacy and patient- and/or family-centered outcomes. This meeting addressed issues of safety, which was defined as "the avoidance of physical or psychological harm." A literature review identified 133 articles addressing safety measures in procedural sedation clinical trials. ⋯ The meeting identified methodological problems associated with measuring infrequent adverse events. With a consensus discussion, a set of core and supplemental measures were recommended to code for safety in future procedural clinical trials. When adopted, these measures should improve the integration of safety data across studies and facilitate comparisons in systematic reviews and meta-analyses.

Observational StudyIntravenous Acetaminophen Does Not Reduce Inpatient Opioid Prescription or Opioid-Related Adverse Events Among Patients Undergoing Spine Surgery.
Having entered the US market relatively recently, the perioperative role of intravenous acetaminophen (ivAPAP) remains to be established for several surgeries. Using national data, we therefore assessed current utilization and whether it reduces inpatient opioid prescription and opioid-related side effects in a procedure with relatively high opioid utilization. ⋯ We could not show that perioperative ivAPAP reduces inpatient opioid prescription with subsequent reduced odds for adverse outcomes. It remains to be determined if and under what circumstances ivAPAP has a meaningful clinical role in everyday practice.

Postoperative Hypotension and Surgical Site Infections After Colorectal Surgery: A Retrospective Cohort Study.
Hypotension compromises local tissue perfusion, thereby reducing tissue oxygenation. Hypotension might thus be expected to promote infection. Hypotension on surgical wards, while usually less severe than intraoperative hypotension, is common and often prolonged. In this retrospective cohort study, we tested the hypotheses that there is an association between surgical site infections and low postoperative time-weighted average mean arterial pressure and/or postoperative minimum mean arterial pressure. ⋯ Postoperative time-weighted mean arterial pressure was not associated with surgical site infection, but lowest postoperative mean arterial pressure was. Whether the relationship is causal remains to be determined.

Incidence and Epidemiology of Perioperative Transfusion-Related Pulmonary Complications in Pediatric Noncardiac Surgical Patients: A Single-Center, 5-Year Experience.
Transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO) are the leading causes of transfusion-related fatalities. While these transfusion-related pulmonary complications (TRPCs) have been well detailed in adults, their burden in pediatric subsets remains poorly defined. We sought to delineate the incidence and epidemiology of pediatric TRPCs after intraoperative blood product transfusion. ⋯ TRPCs occurred in 3.6% of transfused pediatric surgical patients, with the majority of cases attributable to TACO, congruent with adult literature. The frequency of TRPCs was comparable between genders and across surgical procedures and transfusion volumes. The observed trend toward increased TRPCs in younger children warrants further consideration in future investigations. Red blood cell administration was the associated component for the majority of TRPCs, although platelets demonstrated the highest risk per component transfused. Mitigation of perioperative risk associated with TRPCs in pediatric patients is reliant on further multiinstitutional studies powered to examine patterns and predictors of this highly morbid entity.

Recommendations for the Nomenclature of Cognitive Change Associated With Anaesthesia and Surgery-2018.
Cognitive change affecting patients after anaesthesia and surgery has been recognised for more than 100 yr. Research into cognitive change after anaesthesia and surgery accelerated in the 1980s when multiple studies utilised detailed neuropsychological testing for assessment of cognitive change after cardiac surgery. This body of work consistently documented decline in cognitive function in elderly patients after anaesthesia and surgery, and cognitive changes have been identified up to 7.5 yr afterwards. ⋯ For clinical purposes, it is recommended to use the DSM-5 nomenclature. The working group recommends that 'perioperative neurocognitive disorders' be used as an overarching term for cognitive impairment identified in the preoperative or postoperative period. This includes cognitive decline diagnosed before operation (described as neurocognitive disorder); any form of acute event (postoperative delirium) and cognitive decline diagnosed up to 30 days after the procedure (delayed neurocognitive recovery) and up to 12 months (postoperative neurocognitive disorder).
