    Notes: Needle performance is primarily judged by its penetration through tissue. For detailed studies of needle performance, tissue is too heterogeneous and unstable and difficult to obtain. A homogeneous, stable, and readily available polyurethane substrate has been evaluated as a suitable alternative to biological tissue for evaluation of needle penetration. The needle penetration profiles through the synthetic substrate correlated very well with those through natural tissue. In addition, the synthetic substrate was sensitive enough to easily detect a 20% increase in the force necessary to penetrate natural tissue. This polyurethane substrate offers a valid alternative to biological tissue for the testing of needle penetration performance. © 1993 John Wiley & Sons, Inc.

    Notes: The purpose of this study was to determine the influence of the surgeon's tying techique on knot security using 0 and 2-0 monofilament and multifilament nylon sutures. Using an Instron® Tensile Tester and a portable tensiometer, knot security was achieved with these sutures using four-throw square knots (1=1=1=1). After didactic and psychomotor skill training, medical students were taught to construct the four-throw square knot using either a two-hand tie or an instrument tie. Using the portable tensionmeter, their knot tying techniques were judged to be superior to those used by surgeons. The surgeon's faulty technique can easily be corrected by didactic information and psychomotor skill training. © 1993 John Wiley & Sons, Inc.

    Notes: Holes in surgical gloves are considered to be an important source of transmission of pathogens between patient and surgeon. The purpose of this study was to determine if electrosurgery could alter the integrity of latex surgical gloves. The effects of electrosurgery on 11 brands of commercially available latex surgical gloves were tested through an in vitro study that simulated the conditions in the operating room. Glove hole puncture was encountered only with coagulation current operating at the highest setting. In addition, maximal surface area contact with the hemostat to the glove surface was required to produce glove puncture. The presence of powder and glove hydration were not significant determinants of glove hole puncture. On the basis of our study, we believe that all surgical gloves tested offered the surgeon adequate protection at commonly used levels of cutting and coagulation current, as long as no breach existed prior to the donning of gloves. © 1996 John Wiley & Sons, Inc.

    Notes: There are a wide variety of powder-free gloves that can now be used by surgeons. The purpose of this study was to quantify the forces required to don these powder-free surgical gloves. The lowest donning forces for wet hands was encountered with powder-free gloves coated with a hydrogel polymer. In addition, the hydrogel coated gloves exhibited the least increase in donning forces from dry hands to wet hands. While greater forces were encountered with the other commercially available powder-free gloves than the hydrogel coated gloves, they all could be safely donned on dry hands without tearing. © 1996 John Wiley & Sons, Inc.

    Notes: Because needle bending resistance is such an important factor in the selection of surgical needles, a standard quantitative test of needle bending has been devised to study the biomechanics of deformation of needles from three different commercial manufactures. The superior resistance to deformation of needles made by one manufacturer has been related to the specific alloy, ASTM 45500 stainless steel, employed in its production. The needles produced from ASTM stainless steel 45500 have stronger tensile and yield strengths than those of the other alloys, accounting for their greater resistance to bending.

    Notes: New puncture resistant materials are being developed for health professional use as protection against disease and needle stick injuries. The needle puncture resistance of protective gloves and glove liners from DePuy DuPont Orthopaedics and of finger guards from Zimmer was evaluated using a computerized needle penetration system to determine maximal penetration forces and the penetration work required for taper point and for cutting edge needles to penetrate these membranes. The MedakTM portion of the Life LinerTM glove liner and the Spectra© portion of the FingGuardTM finger guard offered remarkable resistance against needle penetration as compared to the other glove liners and gloves tested. The cutting edge needles required considerably less penetration force and work to penetrate the FingGuardTM and Life LinerTM than that required with comparable sized taper point needles. Because these unique protective materials had a limited distribution over the hand, the surgeon's hand remained susceptible to inadvertent needle puncture. While this protection against needle penetration in the Life LinerTM and the FingGuardTM represents an exciting advance in surgery, it is important to emphasize that this development is only one consideration in the selection of surgical gloves. © 1996 John Wiley & Sons, Inc.

    Notes: There are a wide variety of latex examination gloves now available for use by health care providers. A prospective randomized trial was completed to quantify the forces required to don a sample of seven cornstarch-lubricated gloves and 13 powder-free latex examination gloves. The data collected was analyzed by a 20 × 2 general factorial ANOVA, as well as two 1-way ANOVAs using a least significance difference post hoc test. Some powder-free gloves can be easily donned with dry or wet hands without tearing with forces comparable to those encountered with powdered gloves. With the advent of these powder-free examination gloves, powdered gloves can now be abandoned, protecting health professionals and patients from the dangers of absorbable dusting powders. Despite the dangers of the absorbable dusting powders and the Food and Drug Administration's requirement for labeling examination glove boxes, some manufacturers of powdered examination gloves do not appropriately label their boxes with a warning to the health professional and patient of the presence of powder. © 1998 John Wiley & Sons, Inc.

    Notes: A mechanical performance test using an Instron® Tensile Tester demonstrated the superior handling characteristics of Surgipro suture as compared to Prolene suture that facilitated knot construction without suture breakage. For both granny and square knots, the knot run down forces for the Surgipro sutures were significantly less than those encountered for comparable knots for Prolene sutures. This propensity of the two-throw knots of Surgipro sutures to advance without breakage considerably facilitated knot construction. © 1996 John Wiley & Sons, Inc.
