Comparative Study
[Analgesic alternatives for the control of postoperatory pain in radical mastectomy].
The purpose of preventive analgesia based on regional blocks with local anesthetics is to avoid sharp and hard-to-control pain in the anterior side of thorax and axilla secondary to radical mastectomy. ⋯ Preventive analgesia by direct transoperational block on nerves turned out to be an effective alternative with low level of systemic morbidity, which must be considered to prevent moderate and severe pain syndromes that are difficult to control in thoracic oncological surgery.

This paper reports the testing of a lightweight wearable stereoscopic display during neuroendoscopies and endoscope assisted neurosurgeries. The viewers tested were a binocular (for the surgeon) and a monocular system (for the instrumenting nurse), whose optics are specially designed for wearable, portable applications and comprise a color corrected refractive magnifying system.

Complex regional pain syndrome (CRPS) is a disorder or group of disorders that develop as a consequence of previous trauma with or without evident nerve injury. The syndrome is characterized by presence of spontaneous pain, hyperalgesia and allodynia, sensitive changes, blood flow changes, sweating, and trophic changes. The disease is characterized by symptoms of acute inflammatory states as well as by chronic neuropathic changes. ⋯ Creation of diagnostic criteria has been difficult due to the plentiful symptoms of CRSP. Sympathetic blockade with phentolamine is the most commonly approved examination to diagnose sympathetic maintained pain. Several strategies have been used for treatment of CRPS, but with none of these has sufficient evidence of treatment effectiveness been afforded.

To evaluate hepatic resections in patient with benign and malignant lesions during the years 1997 to 2002 at the Autonomous University Hospital Service of Maracaibo, Venezuela. ⋯ The technique of resection with intraparenchymatous identification of pedicles makes it the most successful technique for hepatic resections.

Randomized Controlled Trial Comparative Study Clinical Trial
[Pulmonary mechanics, oxygenation index, and alveolar ventilation in patients with two controlled ventilatory modes. A comparative crossover study].
To compare in a crossover study pulmonary mechanics, oxigenation index (PaO(2)/FiO(2)), and partial pressure of CO(2) in arterial blood (PaCO(2)) in patients with mechanical ventilation in two controlled ventilatory modes. ⋯ Peak inspiratory pressure (PIP) was higher in VC than in PC (31.5 vs 26 cm H(2)O), which resulted in a significant increase in transpulmonary pressure amplitude difference (DP) (25 vs 19 cm H(2)O). Mean airway pressure (MAP) and OI were lower in VC than in PC (11.5 vs 12 cm H(2)O, and 198.5 vs 215, respectively). Dynamic compliance (DynC) was lower in VC than in PC (20 vs 26 ml/cm H(2)O), p < 0.05 for all values. At constant ventilator settings in the same patient, PC and not VC ventilation decreases PIP (which results in smaller transpulmonary pressure amplitude difference), increases MAP, and DynC and improves the oxygenation index.
