Randomized Controlled Trial Clinical TrialBispectral index monitoring in sevoflurane and remifentanil anesthesia. Analysis of drugs management and immediate recovery.
Recent studies have suggested that electroencephalogram bispectral index (BIS) monitoring can improve recovery after anaesthesia and save money by shortening patients postoperative stay. The aim of the study is to evaluate the management of drugs and to measure immediate recovery after anaesthesia with or without BIS monitoring. ⋯ BIS monitoring decrease both sevoflurane and remifentanil consumption, when compared to anaesthesia without BIS, with an immediate recovery after sevoflurane and remifentanil anaesthesia.

[The PiCCO system with brachial-axillary artery access in hemodynamic monitoring during surgery of abdominal aortic aneurysm].
The haemodynamic monitor PiCCO System, based on transpulmonary arterial thermodilution, has been used with a brachial-axillary access instead of the femoral arterial access during abdominal aortic aneurysm surgical repair. Accuracy and limitations of pulse contour continuous cardiac output (PCCO) were evaluated on the basis of arterial thermodilution cardiac output. The patterns of cardiac index, preload, afterload and cardiac function parameters were also studied in the different phases of the surgical procedure. ⋯ PiCCO System with brachial-axillary arterial access was suitable for haemodynamic monitoring of the abdominal aortic aneurysm surgical repair procedures. PCCO must be recalibrated with arterial thermodilution after aortic cross-clamping and unclamping to avoid an over-estimation and an under-estimation respectively. During aortic cross-clamping GEDV and ITBVI indicated a decreased preload. Other haemodynamic variables were less valuable but EVLWI showed an interesting steady increase during the whole procedure.

The aim of this work is to evaluate the efficacy of a new perioperative approach to improve the outcome and to reduce hospitalisation after abdominal aortic surgery. ⋯ Total intra-venous anaesthesia associated with a thoracic epidural anaesthesia, connected with early rehabilitation may improve the outcome and reduce the length of stay in patients submitted to abdominal aortic surgery.

Randomized Controlled Trial Clinical TrialImproving postoperative analgesia after axillary brachial plexus anesthesia with 0.75% ropivacaine. A double-blind evaluation of adding clonidine.
The aim of this prospective, randomized, double-blind study was to evaluate the effects of adding 1 microg/kg clonidine to 20 ml of ropivacaine 0.75% for axillary brachial plexus anesthesia. ⋯ Adding 1 microg/kg clonidine to 20 ml of ropivacaine 0.75% for axillary brachial plexus anesthesia provided a 3 h delay in first analgesic request postoperatively, without clinically relevant effects on the degree of sedation and cardiovascular homeostasis.
