A portable tensiometer for assessing knot-tying technique.

The purpose of this study was to determine the influence of orthopedic surgeons' tying techniques on knot security using 2-0 and 4-0 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 tensiometer, their knot-tying techniques were judged to be superior to those used by orthopedic surgeons. The orthopedic surgeon's faculty technique can easily be corrected by didactic information and psychomotor skill training.

Influence of surgeon's tying technique on knot security.

The purpose of this study was to determine the influence of the surgeon's tying technique 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 tensiometer, 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.

A portable tensiometer for assessing surgeon's knot tying technique.

The purpose of this study was to determine the influence of surgeon's tying technique on knot security using O and 2-O monofilament and multifilament nylon sutures. By use of 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. By use of the portable tensiometer, their knot tying techniques were judged to be superior to those used by a cohort of obstetricians and gynecologists. The surgeon's faulty technique can easily be corrected by didactic information and psychomotor skill training.

Technical considerations in manual and instrument tying techniques.

The purpose of this study was to relate the two-hand (manual) and instrument tie techniques with the ultimate security of granny and square knots constructed in multifilament and monofilament nylon sutures. Instrument-tie technique constructed secure granny and square knots, which failed by breakage rather than slippage. Similarly, two-hand (manual) tie techniques constructed square knots, which achieved knot security, failing only by breakage. In contrast, knot security was not reliably achieved with granny knots constructed by the two-hand (manual) tie techniques, with the knots frequently failing by slippage.

Influence of emergency physician's tying technique on knot security.

The purpose of this study was to determine the influence of emergency physician's tying technique on knot security using 2-0 and 4-0 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 tensiometer, their knot tying techniques were judged to be superior to those used by emergency physicians. The emergency physician's faulty technique can easily be corrected by didactic information and psychomotor skill training.

Aquatic access for the disabled.

Innovations in rehabilitation engineering can now provide aquatic access for the disabled. In the regional burn center, the Bodi-Gard cart shower system (Hospital Therapy Products, Inc., Wood Dale, Ill.) uses three flexible hoses to provide precise hydrotherapy and debridement. Its main mixing valve controls temperature and pressure and is easily disinfected by an in-line chamber. This shower system is complemented by the foldable Bodi-Gard mobile seat shower system (Hospital Therapy Products, Inc.). This system, which is covered by a disposable liner, surrounds the patient with eight water jets that empty into any floor drain. The Bather 2001 (Silcraft Corp., Traverse City, Mich.) is a fiberglass hydrotherapy bathtub with a unique Aqua-Seal door (Silcraft Corp.) that can be raised to provide patient access. Its unique closed-loop disinfection system prevents contamination of its internal components. The Nolan Tublift (Aquatic Access, Louisville, Ky.) is a lightweight, removable lift that uses water power to gently raise and lower its seat. It can be manually swiveled to allow access from a wheelchair. Transfer benches span the tub wall to provide access to the shower and bathtub. Although they are a less expensive alternative to the Tublift, they allow water to spill outside the tub, which may create a slippery bathroom floor. The Nolan Poolift (Guardian Products, Arleta, Calif.) is a water-powered pool lift, which automatically rotates as it descends. It is capable of lifting up to 135 kg with a home water pressure of 55 psi. In contrast, the water-powered Aquatic Access Poolift is a less expensive pool lift, which rotates manually with assistance.(ABSTRACT TRUNCATED AT 250 WORDS)
