Effectiveness of vasectomy using cautery
BACKGROUND Little evidence supports the use of any one vas occlusion method. Data from a number of studies now suggest that there are differences in effectiveness among different occlusion methods. The main objectives of this study were to estimate the effectiveness of vasectomy by cautery and to describe the trends in sperm counts after cautery vasectomy. Other objectives were to estimate time...
متن کاملNonslip Breast Retractors with Cautery Tip Cleaners
Fig. 1. Epstein breast retractor (ASSI, with permission from Accurate Surgical & Scientific Instruments Co. [1]). Fig. 2. Composition of cautery tip cleaners (Xodus). retraction of slippery muscle tissue by stainless steel retractors can be a hindrance during surgery. To overcome this situation, breast retractors with toothed ends are made and sold (Fig. 1) [1, 2]. However, they are not produce...
متن کاملNeuroprotection due to irrigation during bipolar cautery.
OBJECTIVE To test whether irrigation during bipolar cautery confers thermoprotection from neuronal injury. DESIGN A rat animal model (15 rats for each treatment group) was used to test the thermoprotective effects of irrigation during bipolar cautery. In this model, the sciatic nerve was exposed, and a 1-second stimulus was applied using bipolar cautery forceps at 40 or 20 W placed directly o...
متن کاملAn oscillatory current in sheep cardiac Purkinje fibers.
The inward current ("oscillatory current") which may be present after the end of a depolarizing clamp was studied in sheep cardiac Purkinje fibers by means of a voltage-clamp method. The following results were obtained. In order to appear, the oscillatory current (Ios) requires a previous depolarization to approximately or equal to -20 mV or beyond and a repolarization to approximately or equal...
متن کاملFrom biomechanics to sport psychology: the current oscillatory approach
Brain oscillations are, perhaps paradoxically, crucial for movement stability and high performance. Much of what is known about brain oscillations and their relation to movement, sensation and cognition has been established during the last three decades through an explosion of research ranging from in vitro (Draguhn et al., 1998; Fisahn et al., 1998) to in vivo (Cheron et al., 2015) and computi...
