Randomized Controlled Trial
Morphine and Hydromorphone Effects, Side Effects and Variability - a Crossover Study in Human Volunteers.
Balancing between opioid analgesia and respiratory depression continues to challenge clinicians in perioperative, emergency department, and other acute care settings. Morphine and hydromorphone are postoperative analgesic standards. Nevertheless, their comparative effects and side effects, timing, and respective variabilities remain poorly understood. This study tested the hypothesis that IV morphine and hydromorphone differ in onset, magnitude, duration, and variability of analgesic and ventilatory effects. ⋯ For morphine compared to hydromorphone, analgesia and analgesia relative to respiratory depression were less, onset of miosis and respiratory depression was later, and duration of respiratory depression was longer. For each opioid, timing of the various clinical effects was not coincident. Results may enable more rational opioid selection, and suggest hydromorphone may have a better clinical profile.

Paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs) and opiates/opioids, administered parenterally via intravenous or intramuscular route, are widely used to provide analgesia for patients with moderate to severe pain. This systematic review and meta-analysis evaluated the level of analgesia provided by intravenous paracetamol (IVP) alone compared with NSAIDs (intravenous or intramuscular), or opioids (intravenous) alone in adults attending the ED with acute pain. ⋯ CRD42021240099.

Common street drug names for the anesthesiologist and pain physician.
People who use or sell drugs develop their own in-group terms and language, much like any other group of people with a common experience. Slang terms are derived from a wide variety of sources. These might include the physical appearance and/or type of drug, the place where it originates, the effect it has on users, or how it is packaged for sale. To assist and educate the clinical practitioner who may deal with this nomenclature, we have compiled a list of some of the most common street names and some explanations (when known) of their origins.

Observational Study
Intraoperative hydromorphone decreases postoperative pain: an instrumental variable analysis.
Intraoperative administration of short-acting opioids might lead to increased postoperative pain and opioid requirements. There are few data describing the effects of intermediate-duration opioids such as hydromorphone on these outcomes. We have previously shown that a switch from a 2 mg to a 1 mg vial of hydromorphone was associated with decreased intraoperative dose administration. As presentation dose affected intraoperative hydromorphone administration and was unrelated to other policy changes, it could serve as an instrumental variable, assuming significant secular trends were not present during the study period. ⋯ This study suggests that intraoperative administration of intermediate-duration opioids does not cause the same effects as short-acting opioids with respect to postoperative pain. Instrumental variables can be used to estimate causal effects using observation data when unmeasured confounding is present.

Patients undergoing intracranial surgery experience significant perioperative pain and are typically treated with short-acting opioids. Methadone, with its prolonged half-life and multimodal central nervous system effects, presents a promising option for managing postcraniotomy pain. Despite its proven efficacy in other types of surgeries, the use of methadone in patients undergoing craniotomy has not yet been explored. ⋯ The single intraoperative dose of methadone is well tolerated by adult patients undergoing various types of intracranial surgeries, with minimal side effects, including elderly patients aged 65 years or older.
