Randomized Controlled Trial Comparative Study Clinical Trial
Pulse oximeter performance during desaturation and resaturation: a comparison of seven models.
To compare pulse oximeter performance during induced hypoxemia. ⋯ Most models of oximeters tested performed well when hemoglobin oxygen saturation was high, but all were inaccurate when SaO2 was approximately 75%. During induced hypoxemia, there were significant differences in the response times of oximeters tested, with no model demonstrably superior to others in all measures of performance.

Thrombelastography (TEG), which evaluates the elastic properties of whole blood and provides a global assessment of hemostatic function, is useful in managing peripartum coagulopathy. A case of severe bleeding after vaginal delivery, in which TEG was used successfully to manage hemostatic defects, is presented.

Priming with rocuronium accelerates the onset of neuromuscular blockade.
To investigate the effects of priming rocuronium on the time course of neuromuscular blockade. ⋯ Priming rocuronium decreased the onset times and thus, the intubating times without increasing the clinical duration of action or recovery index.

Postoperative analgesia with parenteral opioids: does continuous delivery utilizing a transdermal opioid preparation affect analgesic efficacy or patient safety?
To compare, in patients who underwent major orthopedic surgical procedures, the efficacy of intravenous (IV) patient-controlled analgesia (PCA) with morphine combined with continuous administration of two doses of fentanyl or placebo via transdermal therapeutic system with fentanyl (TTSF) patches. ⋯ There is no significant advantage to the routine use of continuous transdermal opioid delivery in patients receiving IV PCA after major orthopedic surgery.

Comparison of general anesthesia with and without lumbar epidural for total hip arthroplasty: effects of epidural block on hip arthroplasty.
To determine whether lumbar epidural anesthesia, when combined with general anesthesia, decreases perioperative blood loss, the incidence of postoperative deep vein thrombosis (DVT), cardiac dysrhythmias, and ischemia in patients undergoing total hip arthroplasty (THA). ⋯ Combined regional-general anesthesia decreases intraoperative blood loss in THA, and thereby offers an advantage over general anesthesia alone.
