The population of older adults is rapidly growing. With the continued advancement of medical and surgical interventions, the average age of this population will continue to increase. Nearly one-third of surgical procedures are performed in older adults. ⋯ Anesthesia providers can play a key role in creating perioperative geriatric pathways. The perioperative care of a geriatric patient is associated with unique and anesthetic risks. Perioperative care must be tailored to individual patients to reduce perioperative complications in this important, vulnerable population.

ReviewA survey of postoperative pain treatments and unmet needs.
More than 300 million patients undergo surgery worldwide each year. Pain associated with these procedures is associated with short- and long-term negative sequelae for patients, healthcare providers, and healthcare systems. The following chapter is a review of the reality of postoperative pain management in everyday clinical routine based on survey- and registry-derived data with a focus on care in adults. ⋯ Pain assessment is not effectively implemented in many hospitals and should consider cultural differences. Few data exist on the situation of pain management in low- and middle-income countries, indicating lack of resources and available medication in many of these areas. Certain types of surgery as well as demographic and clinical factors are associated with increased risk of severe postoperative pain.

Case ReportsKetoacidosis in Euglycemic Patients With Type 2 Diabetes After Abdominal Surgery.
Diabetic ketoacidosis is defined as hyperglycemia >250 mg/dL with metabolic acidosis of arterial pH <7.3, serum bicarbonate <18 mEq/L with positive urine and serum ketones and an anion gap >10. Euglycemic ketoacidosis has been reported in patients with type 2 diabetes and in patients with type 1 diabetes. ⋯ Both patients developed altered mental status, metabolic acidosis with a bicarbonate level as low as 14 mEq/L, and an anion gap > 18, without hyperglycemia. Both patients had β-hydroxybutyrate levels > 5 mmol/L.

Randomized Controlled TrialNeurocognitive performance under combined regimens of ketamine-dexmedetomidine and ketamine-fentanyl in healthy adults: A randomised trial.
Analgesic doses of ketamine affects neurocognition; however, deficits under co-administration regimens are unknown. This study evaluated the effects of ketamine, alone and in combination with dexmedetomidine or fentanyl on neurocognition. Using a randomised, within-subjects gender stratified design, 39 participants (mean age = 28.4, SD ± 5.8) received a ketamine bolus of 0.3 mg/kg followed by 0.15 mg/kg/h infusion of ketamine (3 h duration). ⋯ Ketamine, norketamine and dexmedetomidine concentrations were modestly associated with reduced psychomotor speed and accuracy (all p < .05), and an inverse relationship was found between blood concentrations of ketamine, norketamine and dexmedetomidine and performance on memory tasks. Co-administration of ketamine with dexmedetomidine but not with fentanyl exerts synergistic effects on psychomotor performance and memory without executive dysfunction. Assessment of these effects in clinical groups is warranted.
