The human error: delayed diagnosis of intravascular loss of guidewires for central venous catheterization.

We report three recent cases in which there was intravascular loss of the entire guide wire. In one case, this loss was discovered more than three months after the patient's procedure. In another case, the loss was detected one month later, and in the third case, four days was the interval of the loss.

Anaphylactoid reactions after cisatracurium administration in six patients.

We report six cases of anaphylactoid reaction after the administration of the muscle relaxant cisatracurium. They include two first-time documented anaphylactoid reactions after a precurarising dose. These incidents challenge existing views of a substantially reduced anaphylactoid potential of cisatracurium relative to other muscle relaxants.

Pseudocholinesterase-activity reduction during cardiopulmonary bypass: the role of dilutional processes and pharmacological agents.

Unlabelled: 1. Pseudocholinesterase (ChE) activity is a determinant of the elimination kinetics of several drugs used in anesthesia. The time course of ChE activity was investigated in 16 patients undergoing cardiosurgery for a cardiopulmonary bypass (CPB) in normothermia or hypothermia.

Lactated Ringer's solution versus hydroxyethyl starch for volume replacement in autologous blood donors with cardiovascular disease: a controlled, randomized trial.

Background And Objectives: The study was designed to evaluate whether volume replacement following blood donation can prevent arterial hypotension in autologous blood donors with cardiovascular disease.

Materials And Methods: One hundred nineteen autologous blood donors with known cardiovascular disease were randomly allocated to receive, following withdrawal of 500 ml of blood, either no infusion (control group) or a 25 ml/min intravenous infusion of either 1,500 ml of lactated Ringer's solution (LRS) or 500 ml of 6% hydroxyethyl starch (HES). Starting before phlebotomy, arterial blood pressure was measured oscillometrically every 5 min until 90 min after donation.
