Randomized Controlled Trial
APOLLO-2: A Randomized, Placebo and Active-Controlled Phase III Study Investigating Oliceridine (TRV130), a G Protein-Biased Ligand at the μ-Opioid Receptor, for Management of Moderate to Severe Acute Pain Following Abdominoplasty.
The clinical utility of conventional IV opioids is limited by the occurrence of opioid-related adverse events. Oliceridine is a novel G protein-biased μ-opioid receptor agonist designed to provide analgesia with an improved safety and tolerability profile. This phase III, double-blind, randomized trial (APOLLO-2 [NCT02820324]) evaluated the efficacy and safety of oliceridine for acute pain following abdominoplasty. ⋯ Oliceridine is a safe and effective IV analgesic for the relief of moderate to severe acute postoperative pain in patients undergoing abdominoplasty. Since the low-dose regimen of 0.1 mg oliceridine was superior to placebo but not as effective as the morphine regimen, safety comparisons to morphine are relevant only to the 2 equi-analgesic dose groups of 0.35 and 0.5 mg, which showed a favorable safety and tolerability profile regarding respiratory and gastrointestinal adverse effects compared to morphine. These findings support that oliceridine may provide a new treatment option for patients with moderate to severe acute pain where an IV opioid is warranted.

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.

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.

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.
