The PiCCO physiological monitor (Pulsion Medical Systems, Munich, Germany) was used for hemodynamic diagnosis and monitoring of 4 patients: a polytraumatized female patient with septic shock and ventilator-associated pneumonia; a man with congestive heart failure and cor pulmonale who developed acute heart failure while recovering from anterior resection of the rectum; a man with severe head injury and acute respiratory distress syndrome; and a polytraumatized male patient with a myocardial contusion. All were in a life-threatening situation, either immediately as in the case of the patient with myocardial contusion or eventually as in the patient with septic shock. ⋯ New less invasive monitoring systems designed to record parameters similar to those detected by the Swan-Ganz catheter but with fewer complications and risks have become available. One example, the PiCCO monitor, combines arterial thermodilution with analysis of the pulse waveform, providing a series of hemodynamic parameters useful for managing the critically ill patient.

[Effects of sevoflurane on mid-latency auditory evoked potentials and the 95% spectral frequency limit].
To investigate the effects of sevoflurane on mid-latency auditory evoked potentials (MLAEP) and compare them to changes in the encephalographic 95% spectral edge frequency (SEF95). ⋯ Our results indicate that the effect of sevoflurane on the MLEAP of Na, Pa and Nb is similar to that of other anesthetic gases. Even though the amplitude of the Na, Pa and Nb waves decreased in a dose-dependent way, SEF95 correlated more strongly with sevoflurane concentration.

Randomized Controlled Trial Comparative Study Clinical Trial[Sciatic nerve block with 1% mepivacaine for foot surgery: posterior versus lateral approach to the popliteal fossa].
To compare the efficacy and feasibility of the sciatic nerve block performed using either a posterior or a lateral approach to the popliteal fossa, taking into consideration patient comfort during puncture and postoperative analgesia. ⋯ The lateral approach to the block of the sciatic nerve in the popliteal fossa provides analgesia comparable to that obtained with the posterior approach, with a faster onset and longer postoperative duration.

To study the efficacy and complications of a parascalene block over a period of 10 years of experience. ⋯ The parascalene block is a simple, safe, and effective technique. The probability of serious complications is lower than with most known supraclavicular techniques, mainly because the puncture is perpendicular to the horizontal plane. A neurostimulator or aponeurotic click technique is used and the nerve trunks can be found between 1,5 and 2 cm deep when the plexus is located in reference to the transverse processes.
