• COMPLICATIONS
  • 1 This tremendous increase can be linked to the perception that regional anesthesia is associated with numerous advantages and with very few severe complications. (asahq.org)
  • Thus, we created a hotline service (SOS Regional Anesthesia Service) that had three main goals: (1) to provide online clinical help for the practitioner facing a severe complication, (2) to obtain immediately relevant clinical information for every complication reported, and (3) to estimate the incidence of complications from a prospective declaration of all regional techniques performed by practitioners who had subscribed to the service. (asahq.org)

  • nitrous oxide
  • Anesthesia machines may differ in appearance, size and degree of sophistication but generally speaking, they consist of sections for: ventilation space for monitoring equipment accessories storage space worktop It is imperative that essential medical pipeline gas supply, e.g. oxygen], nitrous oxide and air, are secured firmly to the machine, and readily available without any obstructions, defects or pressure leaks. (wikipedia.org)

(wikipedia.org)
  • All of the volatile agents can be used alone or in combination with other medications to maintain anesthesia (nitrous oxide is not potent enough to be used as a sole agent). (wikipedia.org)
  • doses
  • In preparing for a medical procedure, the health care provider giving anesthesia chooses and determines the doses of one or more drugs to achieve the types and degree of anesthesia characteristics appropriate for the type of procedure and the particular patient. (wikipedia.org)
  • Emergence
  • e.g., desflurane) give the anesthesia provider greater rapidity in titrating the depth of anesthesia, and permit a more rapid emergence from the anesthetic state upon discontinuing their administration. (wikipedia.org)
  • In fact, newer volatile agents (e.g., sevoflurane, desflurane) have been popular not due to their potency (minimum alveolar concentration), but due to their versatility for a faster emergence from anesthesia, thanks to their lower blood-gas partition coefficient. (wikipedia.org)
  • lumbar
  • Three minutes of spinal mobilization was delivered to 6 restrained rats at approximately 2 Hertz (Hz) with the experimenter's finger over the lumbar (L5) spinous process beginning 10 minutes after intraplantar hindpaw injection of a mixture of endogenous inflammatory mediators. (hindawi.com)
  • Twenty-four hours later, saddle anesthesia and lumbar pain persisted and, after 48 hours, the patient presented urinary incontinence. (scielo.br)

  • 1995
  • With the formal integration of a team of anesthesia pain specialists into the interdisciplinary Pain and Symptom Management Program at M.D. Anderson, the number of interventions for pain that had failed to respond to systemic therapy increased dramatically, from about 40 in 1993 to more than 300 in 1995. (cancernetwork.com)

  • Pain models that incorporate simulated spinal manipulative therapy treatments are needed for these studies. (hindawi.com)
  • Results from both spinal manipulation and spinal mobilization studies in asymptomatic and symptomatic individuals demonstrate short-term pain relief both remote and local to the anatomical treatment site following a single treatment [ 5 - 16 ]. (hindawi.com)
  • Essential to achieving these goals is basic science research that uses simulated spinal manipulative therapy techniques with experimental pain models. (hindawi.com)
  • While this peripheral inflammatory pain model allowed for a demonstration of an immediate remote antinociceptive effect following spinal mobilization, investigating the effect's duration requires a model with longer-lasting nociception. (hindawi.com)
