Comparative Study
Performance of three new-generation pulse oximeters during motion and low perfusion in volunteers.
To evaluate pulse oximeter performance during motion and induced low perfusion in volunteers. ⋯ The Masimo Radical had higher SpO(2) sensitivity and specificity than the Nellcor N-600 and Datex-Ohmeda TruSat during conditions of motion and induced low perfusion in this volunteer study.

Conditions leading to iron overload range from rare hereditary disorders to more common medical conditions associated with chronic blood transfusions. Iron overload has deleterious effects on various vital organs (eg, liver, heart, and endocrine glands). Serum ferritin (in conjunction with transferrin saturation) is the most widely used test to evaluate iron burden and to screen for iron overload. The management plan should be adjusted to account for iron overload and potential consequences of liver, heart, and other organ involvement.

1) To develop an in vitro system to simulate the kinetics of ionized calcium in mixed venous blood during rapid transfusion of fresh frozen plasma (FFP) and 2) to use the in vitro data to estimate the effect of the transfusion rate relative to cardiac output (CO) on ionized calcium. ⋯ An instantaneous 50% reduction in ionized calcium occurs in vitro at a proportion equivalent to a transfusion rate of FFP representing 7% of CO.

Clinical Trial
The optimal dose of remifentanil for acceptable intubating conditions during propofol induction without neuromuscular blockade.
To determine the optimal remifentanil dose required to provide acceptable intubating conditions following induction of anesthesia with propofol without using neuromuscular blockade. ⋯ The optimal bolus dose of remifentanil for acceptable intubating conditions was 2.40 μg/kg (95% confidence interval, 1.90-9.0 μg/kg) in 95% of patients during induction of anesthesia with propofol 2.0 mg/kg without neuromuscular blocking agents.

To evaluate the analgesic efficacy of transversus abdominis plane (TAP) blocks in patients undergoing ileostomy reversal. ⋯ TAP blocks are an effective means of reducing perioperative pain in patients undergoing ileostomy reversal.
