Measurements of blood flow, velocity, Hb, and SO2 were performed in 196 microvascular flaps, which had been transferred into the oral cavity to reconstruct ablative defects after surgery for oral cancer. The values were calculated superficially on the skin surface and at a depth of 8 mm. The results showed that perioperative absolute values measured were not associated with an increased rate of microvascular revisions or free flap failure. Independent predictors of microvascular revisions at the first postoperative day were the development of a falling trend in superficial and deep blood flow, and velocity in comparison with baseline

values of variables measured. On day 2, all superficial and deep values of Hb, flow, and velocity were independent selleck chemical prognostic factors (P < 0.01), demonstrated as a downward trend were associated with a need for revision. The superficial and deep values of SO2 (P = 0.59 and 0.43, respectively) were not associated with ultimate free flap failure. This is the first clinical study to demonstrate that during early free flap integration to the recipient site different parameters of Selleckchem Dabrafenib perfusion and oxygenation play an important role at different points

of time. Within the first two postoperative days, changes in these parameters can help influence the decision to revise microvascular anastomoses. © 2013 Wiley Periodicals, Inc. Microsurgery 34:345–351, 2014. “
“A comparison of outcomes based on a scoring system for assessments, described by Rosén and Lundborg, after sharp complete laceration of median and/or ulnar nerves at various levels why in the

forearm was carried out. There were 66 males (90.4%) and 7 females (9.6%), with a mean age of 31 years (range: 14–62 years). The patients were categorized into three groups according to the type of nerve injury. The median nerve was injured in 25 cases (group M, 34.3%), the ulnar in 27 (group U, 36.9%), and both the nerves in 21 (group MU, 28.8%). The demographic data of the patients and the mechanism of injury were recorded. We also examined the employment status at the time of the injury and we estimated the percentage of patients who returned to their work after trauma. In all cases, a primary epineural repair was performed. Concomitant injuries were repaired in the same setting. The mean period of time between injury and surgery was 5.3 hours (range: 2–120 hours). A rehabilitation protocol and a reeducation program were followed in all cases. The mean follow-up was 3 years (range: 2–6 years), with more distal injuries having a shorter follow-up period. The total score was 2.71 in group M (range: 0.79–2.99) and 2.63 in group U (range: 0.63–3), with no significant differences observed. There was a significant difference between these two groups and group MU (total score 2.
