Transfusion has no effect on recurrence in hepatitis C after liver transplantation.
The literature suggests that blood product transfusions have a negative impact on the survival of liver transplant patients. We investigated the impact of intraoperative blood product usage on the survival of liver transplantation patients being transplanted for hepatitis C-related end-stage liver disease. In addition, we analyzed a potentially more sensitive metric, namely disease recurrence and fibrosis progression, obtained from follow-up liver biopsies. ⋯ This study was not able to confirm an effect on the survival of HCV-infected liver transplant patients related to intraoperative transfusion of RBCs or platelets. In addition, these transfusions had no effect on HCV recurrence or fibrosis progression. This is not to condone a liberal transfusion practice, but rather to reassure that when clinically indicated, transfusion does not have a significant impact on patient survival or disease recurrence in HCV-infected liver transplant patients.

The effect of a simple checklist on frequent pre-induction deficiencies.
A substantial proportion of anaesthesia-related adverse events are preventable by identification and correction of errors in planning, communication, fatigue, stress, and equipment. The aim of this study was to develop and implement a pre-induction checklist in order to identify and solve problems before induction of anaesthesia. ⋯ It is possible to develop, introduce, and use a pre-induction checklist even in a hectic and stressful clinical environment. The checklist identified and reduced a surprisingly large number of missing items required in a standard induction protocol.

Non-invasive monitoring of blood haemoglobin for analysis of fluid volume kinetics.
A commercially available pulse oximeter that reports blood haemoglobin (Hb) concentration is evaluated. This study considers whether this device can provide serial Hb data that would be sufficiently reliable for volume kinetic analysis of infusion fluids. ⋯ Non-invasive measurement of the Hb concentration during volume loading could not provide useful kinetic data for individuals.

Pulmonary haemodynamics and right ventricular function during cemented hemiarthroplasty for femoral neck fracture.
Bone cement implantation syndrome (BCIS) is characterised by hypoxia, hypotension and loss of consciousness occurring early after bone cementation. The haemodynamic perturbations during BCIS have not been extensively studied, particularly not in patients with femoral neck fracture. We evaluated the effects of cemented hemiarthroplasty, in these patients, on pulmonary haemodynamics, right ventricular performance, intrapulmonary shunting and physiological dead space. ⋯ Cemented hemiarthroplasty in patients with femoral neck fracture causes a pronounced pulmonary vasoconstriction and an impairment of RV function accompanied by pulmonary ventilation/perfusion abnormalities.

Inappropriate withdrawal or continuation of medication in the perioperative period is associated with an increased risk for adverse events. To reduce this risk, it is important that patients take their regular medication as prescribed. We evaluated this treatment objective by studying the frequency and reasons for errors related to medication discontinuity in the perioperative period. ⋯ Medication errors occur frequently in the perioperative period, even in the era of an electronic medication file. Errors in prescription, administration and intake of medication are not easily solved because no single health care professional is responsible for adequate intake of medication in surgical patients. The anaesthesiologist should take on a more prominent role in regulating perioperative medication intake in surgical patients.
