Impact of intraoperative blood salvage on monocyte subsets alteration and intracellular tumor necrosis factor-α production.

Unlabelled: Intraoperative salvaged blood is used to reduce allogeneic blood transfusion in orthopedic surgery patients. However, salvaged blood reinfusion may lead to immune reactions. Salvaged and venous blood from 20 patients undergoing hip arthroplasty was processed.

Impact of intraoperatively salvaged and washed blood on stimulated cytokine release in vitro.

Background: Intraoperative blood salvage and processing it with commercially available devices is a widespread standard procedure to reduce allogeneic blood transfusion in patients undergoing major orthopedic surgery. The aim of this study was to investigate the impact of such processed blood on the immune system by measuring pro- and anti-inflammatory cytokines.

Study Design And Methods: Salvaged blood from 20 patients undergoing hip arthroplasty was processed with a continuous autotransfusion system.

Randomized evaluation of the size 2 laryngeal tube and classical laryngeal mask airway in different head and neck positions in children under positive pressure ventilation.

Purpose: The aim of this study was to evaluate the applicability of the laryngeal tube (LT) size 2 and the classical laryngeal mask airway (LMA) size 2 in different head-neck positions under positive pressure ventilation in children by measuring leak pressures, peak pressures and the achievable tidal volumes under positive pressure ventilation.

Methods: Forty children were randomized to receive airway management by either the LT or LMA as the primary device. Leak pressures, peak pressures and tidal volumes under positive pressure ventilation were measured in the neutral, anteflection, retroversion, left-rotation and right-rotation head-neck positions.

Impact of shed blood products on stimulated cytokine release in an in vitro model of transfusion.

Background: Blood transfusion is reported to suppress the recipient's immune system. To avoid allogenic transfusion, post-operative shed blood retransfusion is a commonly used method. The aim of this study was to investigate the dose-related impact of post-operatively collected shed blood products on the stimulated cytokine release in an in vitro model of transfusion.
