Identifying Patients Experiencing Opioid-Induced Respiratory Depression During Recovery From Anesthesia: The Application of Electronic Monitoring Devices.
Postsurgical patients experiencing opioid-related adverse drug events have 55% longer hospital stays, 47% higher costs associated with their care, 36% increased risk of 30-day readmission, and 3.4 times higher risk of inpatient mortality compared to those with no opioid-related adverse drug events. Most of the adverse events are preventable. ⋯ Electronic monitoring devices are currently used as a tool to assess respiratory status using thresholds to distinguish when respiratory depression has occurred. This study introduces a potential paradigm shift from a reactive approach to a proactive approach that would identify a patient at high risk for OIRD. Capnography and MV were found to be effective tools in detecting respiratory compromise in the PACU.

Randomized Controlled Trial Multicenter Study Comparative Study
Satisfactory analgesia with minimal emesis in day surgeries: a randomised controlled trial of morphine versus hydromorphone.
Opioids remain the mainstay therapy for post-surgical pain. Although both morphine and hydromorphone are potent analgesics, it has been suggested that hydromorphone is clinically better. Our primary objective was to compare morphine with hydromorphone for achieving satisfactory analgesia with minimal emesis (SAME). ⋯ NCT02223377.

Analgesic design and evaluation have been driven by the desire to create high-affinity high-selectivity mu (μ)-opioid peptide (MOP) receptor agonists. Such ligands are the mainstay of current clinical practice, and include morphine and fentanyl. Advances in this sphere have come from designing pharmacokinetic advantage, as in rapid metabolism for remifentanil. ⋯ Recent development has been to move towards low-selectivity multifunctional 'mixed ligands', such as cebranopadol, or ligand mixtures, such as Targinact®. Moreover, the observation that β-arrestin coupling underlies the side-effect profile for MOP ligands (from knockout animal studies) led to the discovery of biased (to G-protein and away from β-arrestin intracellular signalling) MOP ligands, such as oliceridine. There is sufficient excitement in the opioid field to suggest that opioid analgesics without significant side-effects may be on the horizon, and the 'opioid Holy Grail' might be in reach.

The drug-induced, reversible coma of anaesthesia requires three clinical outcomes: unconsciousness, immobility, and the control of autonomic nervous system (ANS) responses to surgical stimulation. Producing the anaesthetised state with a single anaesthetic agent, such as an inhaled vapour or propofol, is challenging, primarily because suppressing ANS responses requires very high anaesthetic concentrations, resulting in haemodynamic depression and prolonged recovery. The antinociceptive effects of opioids (i.e. minimum alveolar concentration reduction) are thus central to the well-entrenched 'balanced anaesthesia' concept. ⋯ But there is a paucity of data on how intraoperative opioid usage patterns may be contributing to persistent opioid use after surgery. There are cogent reasons to moderate perioperative opioid use, including intraoperative opioids, but whether these changes in practice integral to the multimodal general anaesthesia concept will improve anaesthesia outcomes, including persistent opioid use after surgery, is unknown. Studies investigating these issues are an important research priority.
