Uncalibrated continuous cardiac output measurement in liver transplant patients: LiDCOrapid™ system versus pulmonary artery catheter.

Objective: The aim of the study was to assess the level of agreement between continuous cardiac output estimated by uncalibrated pulse-power analysis (PulseCOLiR) and intermittent (ICO) and continuous cardiac output (CCO) obtained using a pulmonary artery catheter (PAC).

Design: Prospective cohort study.

Setting: University hospital intensive care unit.

Effects of catecholamines on microcirculation during general inhalation anesthesia.

Objective: The aim of this study was to investigate the effects of clinical dosages of norepinephrine and dobutamine on sublingual microcirculation during general anesthesia with sevoflurane in minor surgical procedures.

Design: This prospective study was performed on patients scheduled for breast cancer surgery.

Setting: Tertiary care university hospital.

The dos and do knots of central venous catheterization.

Central venous catheterization plays an important role in patients with end-stage renal disease undergoing hemodialysis. Placement of a right subclavian hemodialysis catheter was complicated by looping and entrapment of the guidewire. Computed tomographic and three-dimensional scans were essential in locating and determining that the guidewire was outside the vessel.

Prognostic power of pre- and postoperative B-type natriuretic peptide levels in patients undergoing abdominal aortic surgery.

Objectives: The first aim of the present study was to evaluate the pre- and postoperative B-type natriuretic peptide (BNP) levels in patients undergoing surgery for repair of an infrarenal abdominal aortic aneurysm (AAA) and analyze their power as a predictor of in-hospital cardiac events. The second aim was to evaluate the association among pre- and postoperative BNP levels, postoperative patient complications, and length of hospital stay.

Design: Prospective observational study.
