The most common form of patient-controlled analgesia is self-administration of oral over-the-counter or prescription painkillers. For example, if a headache does not resolve with a small dose of an oral analgesic, more may be taken. As pain is a combination of tissue damage and emotional state, being in control means reducing the emotional ...
Procedural sedation and analgesia (PSA) is a technique in which a sedating/dissociative medication is given, usually along with an analgesic medication, in order to perform non-surgical procedures on a patient. The overall goal is to induce a decreased level of consciousness while maintaining the patient's ability to breathe on their own.
Simply switching the patient from 40 mg of morphine to 10 mg of levorphanol would be dangerous due to dose accumulation, and hence frequency of administration should also be taken into account. There are other concerns about equianalgesic charts. Many charts derive their data from studies conducted on opioid-naive patients.
Fentanyl is sometimes sold on the black market in the form of transdermal fentanyl patches such as Duragesic, diverted from legitimate medical supplies. The gel from inside the patches is sometimes ingested or injected. [166] Another form of fentanyl that has appeared on the streets is the Actiq lollipop formulation.
Midazolam is the only water-soluble benzodiazepine available. Another maker is Roxane Laboratories; the product in an oral solution, midazolam HCl Syrup, 2 mg/mL clear, in a red to purplish-red syrup, cherry in flavor. It becomes soluble when the injectable solution is buffered to a pH of 2.9–3.7. Midazolam is also available in liquid form. [16]
The patient presses a button to activate a syringe device and receive a preset dose or "bolus" of the drug, usually a strong opioid such as morphine, fentanyl, or oxycodone (e.g., one milligram of morphine). The PCA device then "locks out" for a preset period to allow the drug to take effect, and also prevent the patient from overdosing.
Patient and doctor describing state of consciousness similar to "twilight anesthesia" Twilight anesthesia is an anesthetic technique where a mild dose of sedation is applied to induce anxiolysis (anxiety relief), hypnosis, and anterograde amnesia (inability to form new memories). The patient is not unconscious, but sedated.
Sedation scales are used in medical situations in conjunction with a medical history in assessing the applicable degree of sedation in patients in order to avoid under-sedation (the patient risks experiencing pain or distress) and over-sedation (the patient risks side effects such as suppression of breathing, which might lead to death).
