Submerged vascular anastomosis. A technique for vascular suturing in experimental microsurgery.

Purpose: To evaluate the impact of submersion of the microsurgical anastomosis suture area using saline (0.9% NaCl) in an experimental laboratory during the training of medical students and resident physicians.

Methods: Wistar rats (n = 10) were selected to have the two femoral arteries sectioned and anastomosed end-to-end under optical magnification.

Does washing medical devices before and after use decrease bacterial contamination?: An in vitro study.

Surface treatment of medical devices may be a way of avoiding the need for replacement of these devices and the comorbidities associated with infection. The aim of this study was to evaluate whether pre- and postcontamination washing of 2 prostheses with different textures can decrease bacterial contamination.The following microorganisms were evaluated: Staphylococcus aureus, Staphylococcus epidermidis, Proteus mirabilis and Enterococcus faecalis.

Animal model of rapid crystalloid infusion in rats.

Purpose: To describe an animal model of rapid intravenous infusion with different volumes of crystalloid and discuss the clinical findings.

Methods: Fifty six male Wistar rats were used, divided randomly in seven groups (n = 8). The rats of groups 1 to 6 received lactated Ringer's solution intravenously, in the rate of 25 ml/min, with different volumes proportional to blood volume (BV).

Intermaxillary fixation as co-adjuvant treatment for morbid obesity.

Background: The effective long-term treatments for morbid obesity is bariatric surgery. However, the associated surgical and anesthetic risks led the authors to evaluate intermaxillary fixation, a less aggressive procedure, as a preoperative treatment in selected patients with morbid obesity.

Methods: 22 patients (5 male, 17 female, ages 16-53 years, with BMI 44.
