[Anesthetic requirements measured by bilateral bispectral analysis and femoral blockade in total knee arthroplasty].

Background And Objectives: A continuous peripheral nerve blockade has proved benefits on reducing postoperative morphine consumption; the combination of a femoral blockade and general anesthesia on reducing intraoperative anesthetic requirements has not been studied. The objective of this study was to determine the relevance of timing in the performance of femoral block to intraoperative anesthetic requirements during general anesthesia for total knee arthroplasty.

Methods: A single-center, prospective cohort study on patients scheduled for total knee arthroplasty, were sequentially allocated to receive 20mL of 2% mepivacaine throughout a femoral catheter, prior to anesthesia induction (Preoperative) or when skin closure started (Postoperative).

The bilateral bispectral and the composite variability indexes during anesthesia for unilateral surgical procedure.

Background: The composite variability index (CVI), derived from the bispectral analysis (BIS), has been designed to detect nociception; however, there is no evidence that bilateral BIS and CVI show intrapatient reproducibility or variability.

Methods: We conducted an observational study in patients who underwent for total knee arthroplasty. A BIS Bilateral Sensor was applied and continuously recorded at different points of the anesthesia procedure.

Hypocapnia and hyperoxia induction using a hyperventilation protocol in electroconvulsive therapy.

Introduction: Hyperventilation in electroconvulsive therapy sessions has been associated with seizure threshold, seizure characteristics, and cognitive effects. There is no consensus on the optimal procedure of applying hyperventilation manoeuvres during electroconvulsive therapy.

Material And Methods: Prospective evaluation of the effects of systematic use of hyperventilation manoeuvres with facial mask and capnography (protocolized hyperventilation [pHV]), on ventilation parameters and on seizures.

High-dose intravenous treatment in iron deficiency anaemia in inflammatory bowel disease: early efficacy and impact on quality of life.

Background: Anaemia and iron deficiency are very common in inflammatory bowel disease. Clinical trials have shown intravenous iron to be effective and well tolerated. However, published experience in clinical practice with specific evaluation of the effect on quality of life is limited.

Ultrasound-guided saphenous nerve block is an effective technique for perioperative analgesia in ambulatory arthroscopic surgery of the internal knee compartment.

Objectives: Arthroscopic knee surgery is a minimally invasive technique with moderate pain during the first 24h. Our main objective was to evaluate the efficacy of ultrasound guided saphenous nerve block as a method of pain control intraoperatively and postoperatively for this surgery.

Material And Methods: A prospective and observational study.

Urodynamics prior to renal transplantation--its impact on treatment decision and final results.

Objective: To evaluate the role of urodynamics prior to renal transplantation in a selected group of patients.

Material And Methods: This retrospective study included 44 consecutive patients (20 males, 24 females; age range 7-57 years; mean age 27.14 +/- 15.
