Intravenous acetaminophen injection (paracetamol) is marketed in Europe for the management of acute pain. A repeated-dose, randomized, double-blind, placebo-controlled, three-parallel group study was performed to evaluate analgesic efficacy and safety intravenous as compared with its prodrug (propacetamol) placebo. Propacetamol has been available many European countries more than 20 yr.After orthopedic surgery, patients reporting moderate severe pain received either 1 g acetaminophen, 2...

Background: The ability of hemoglobin based oxygen carrier-201 (HBOC-201) to safely reduce and/or eliminate perioperative transfusion was studied in orthopedic surgery patients. Methods: A randomized, single-blind, packed red blood cell (PRBC)-controlled, parallel-group multicenter study conducted. Six hundred eighty-eight patients were randomized treatment with HBOC-201 (H, n = 350) or PRBC (R, 338) at the first decision. Primary endpoints avoidance and blinded assessment [Mann-Whitney...

Hemoglobin-based oxygen carriers (HBOCs) have a long history of development, yet none are currently licensed for use in the US. Early HBOC studies were interested toxicity infused hemoglobin, followed by Amberson and colleagues from University Maryland.1 As early as 1934, purified bovine hemoglobin it into cats. In 1949, he described human anemic parturients with hemorrhage after childbirth.2 Development continued when US Army manufactured tetrameric cross-linked (α-α hemoglobin), which...

Abstract Background and Methods: From the time that Sinatra et al. ( Anesthesiology . 2005; 102 :822) was published to FDA apaproval of intravenous (IV) acetaminophen, an expanded analysis original raw study data became necessary for regulatory submission. The following analyses were conducted: (1) sum pain intensity differences over 24 hours (SPID24) using currently accepted imputation methods account both missing effects rescue; (2) efficacy results after first 6 hours; (3) gender,...

Despite advances in pharmacologic options for the management of surgical pain, there appears to have been little or no overall improvement over last two decades level pain experienced by patients. The importance adequate and effective management, however, is clear, because inadequate control 1) has a wide range undesirable physiologic immunologic effects; 2) associated with poor outcomes; 3) increased probability readmission; 4) adversely affects cost care as well patient satisfaction. There...

Inadequate control of postoperative pain after orthopedic procedures may trigger complications that increase morbidity. Multimodal analgesia is used to manage effectively surgical and reduce the need for rescue analgesia. Intravenous (IV) acetaminophen (OFIRMEV; Cadence Pharmaceuticals, Inc.), an analgesic has been studied in multimodal management acute major procedures, combines safety seen with oral rectal formulations a preferred route administration. Two double-blind, randomized,...

Perflurocarbon-based oxygen carriers (PBOC) represent a major category of artificial therapeutics. Since their initial report potential oxygen-carrying capability half century ago, some PBOC products have been developed for the purpose Unfortunately, majority these discontinued due to side effects, such as Flusol-DA-20, Oxygent, and Oxycyte. is unique its inorganic nature relatively smaller molecules, making it possible production in massive quantity.

Clinical features: Sickle cell patients may develop a multitude of antibodies and experience life-threatening events with transfusion such as hyperhemolysis syndrome or delayed hemolytic reaction. Further not be possible in cases. Therapeutic Challenge: When conventional blood products are available for yet the patient requires additional oxygen-carrying support, artificial oxygen carriers required. However, there no FDA-approved available. Solution: Emergency investigational new drug...
