Review Multicenter Study
Complications related to less-invasive haemodynamic monitoring.
The aim of this study was to evaluate the type and incidence of complications during insertion, maintenance, and withdrawal of central arterial catheters used for transpulmonary thermodilution haemodynamic monitoring (PiCCO™). ⋯ In this series of patients, central arterial catheters used for PiCCO™ monitoring were demonstrated to be a safe alternative for advanced haemodynamic monitoring.

As ropivacaine and its metabolites are excreted by the kidneys, we studied their disposition in subjects with renal dysfunction. ⋯ The pharmacokinetics of ropivacaine is not affected by renal failure. Although the renal clearance of PPX correlates with CL(CR), non-renal elimination seems to compensate for reduced renal clearance in most patients. PPX may accumulate in plasma during long-term postoperative infusions, in particular in patients with co-existing low non-renal elimination. Systemic toxicity is still unlikely because PPX is markedly less toxic than ropivacaine.

Surgical repair of hip fractures is associated with high postoperative mortality. The identification of high-risk patients might be of value in aiding clinical management decisions and resource allocation. The Nottingham Hip Fracture Score (NHFS) is a scoring system validated for the prediction of 30 day mortality after hip fracture surgery. It is made up of seven independent predictors of mortality that have been incorporated into a risk score: age (66-85 and ≥86 yr); sex (male); number of co-morbidities (≥2), admission mini-mental test score (≤6 out of 10), admission haemoglobin concentration (≤10 g dl(-1)), living in an institution; and the presence of malignancy. We investigated whether the NHFS was a predictor of 1 yr mortality in patients undergoing surgical repair of fractured neck of femur. ⋯ NHFS can be used to stratify the risk of 1 yr mortality after hip fracture surgery.
