Rescue Analgesic Use

Rescue analgesic use is the administration of an additional, as-needed pain medication when a patient experiences breakthrough pain despite a baseline analgesic regimen. The rescue dose provides short-term relief by supplementing ongoing treatment, with its effects depending on the drug’s mechanism, such as reduced prostaglandin-mediated inflammation with nonsteroidal anti-inflammatory drugs or altered pain signaling with opioids. In medicine, clinicians use rescue therapy to preserve comfort during acute flares, procedures, or recovery while monitoring pain intensity, timing, treatment response, adverse effects, and total medication exposure. Careful assessment helps guide regimen adjustments and reduce risks such as oversedation, toxicity, or inadequate pain control.

Capsulorhexis is an important step in phacoemulsification surgery. A surgeon creates a continous curvilinear tear on the anterior lens capsule by controlling the tearing vector forces. A peripherally extended tear is a serious complication. This video demonstrates a novel technique of rescuing capsular radial tear out using a cystotome.

Source: Martinez, E., et al. Intracranial Pharmacotherapy and Pain Assays in Rodents. J. Vis. Exp. (2019).This video demonstrates the intracranial administration of an analgesic drug in an anesthetized rat with a pre-implanted guide cannula in the prefrontal cortex. An additional analgesic drug is co-administered intraperitoneally. Following recovery, the rat’s thermal pain response is assessed using Hargreave’s apparatus, where paw withdrawal latency is measured to evaluate the analgesic...

Assessment of Morphine-induced Hyperalgesia and Analgesic Tolerance in Mice Using Thermal and Mechanical Nociceptive Modalities

2014

We describe a protocol to examine the development of opioid-induced hyperalgesia and tolerance in mice. Based on the measurement of thermal and mechanical nociceptive responses of naïve and morphine-treated animals, it allows to quantify the increase in pain sensitivity (hyperalgesia) and decrease in analgesia (tolerance) associated with chronic opiate administration.

Opioid Analgesics: Synthetic and Semisynthetic Opioids

0 Views •

2024

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
