Tissue blood flow reductions induced by remifentanil in rabbits and the effect of naloxone and phentolamine on these changes.
The purpose of this study was to investigate the effects of naloxone and phentolamine on the blood flow changes in rabbit oral tissue induced by remifentanil during sevoflurane anesthesia. ⋯ Remifentanil deceased oral tissue blood flow and systemic hemodynamic variables. Naloxone and phentolamine produced a recovery of oral tissue blood flow with and without systemic hemodynamic recovery, respectively.

Venous anastomoses using microvascular coupler in free flap head and neck reconstruction.
This study is a retrospective review of the experience using the venous coupler for head and neck reconstruction over a 3-year period at the University of Maryland Medical Center, Department of Oral and Maxillofacial Surgery. ⋯ The microvascular coupler is reliable for venous anastomosis in free flap head and neck reconstruction; dual-vein anastomoses appear to have better results than single-vein anastomoses. Flow coupler has a promising utility in monitoring buried flaps and flaps that are difficult to observe. The microvascular coupler deserves to be more commonly used in free flap head and neck reconstruction.
