A two-stage approach to positioning and identification of tracheal intubation using LED-based lightwand and acoustic models.

This paper proposes a two-stage approach to positioning and identifying tracheal intubations by computer-assisted diagnosis system. First, an innovated LED-based lightwand is developed for positioning the opening of the trachea and inserting the endotracheal tube rapidly. The proposed LED-based lightwand instrument significantly reduces the effects of temperature reaction without changing transillumination through the tissue.

Pharmacokinetics and nephrotoxicity of aristolochic acid in rabbits.

Aristolochic acids (AAs) which exist in plants of the genus Aristolochia are the toxins responsible for aristolochic acid nephropathy (AAN). To investigate the pharmacokinetics and nephrotoxicity of AAs, rabbits were used in this study. The plasma concentrations of the main components of AAs, aristolochic acid I (AA I) and aristolochic acid II (AA II), were determined by a validated high-performance liquid chromatographic method.

Effect of autologous blood donation on the central venous pressure, blood loss and blood transfusion during living donor left hepatectomy.

Aim: Autologous blood donation (ABD) is mainly used to reduce the use of banked blood. In fact, ABD can be regarded as acute blood loss. Would ABD 2-3 d before operation affect the CVP level and subsequently result in less blood loss during liver resection was to be determined.

Maintenance of normothermia at operation room temperature of 24 degrees C in adult and pediatric patients undergoing liver transplantation.

Hypothermia is common during surgery in regular operating room (OR) temperature. The effect of increasing the OR temperature to 24 degrees C coupled with simple warming measures to maintain normothermia in both pediatric and adult patients during living donor liver transplantation (LDLT) was evaluated. One hundred patients undergoing LDLT were separated into pediatric (GI) and adult (GII) groups.
