Safe use of lasers in the operating room-what perioperative nurses should know.

SAFETY HAZARDS are inherent in laser use, but they can be eliminated or significantly reduced with adherence to proper procedures. THIS ARTICLE reviews beam-related and nonbeam-related safety hazards, including eye injuries, fire and thermal injuries, smoke plume, and electrical hazards, as well as safety measures to avoid these hazards. EDUCATION IN LASER SCIENCE and safety is key to recognizing potential hazards and ensuring that safety parameters are followed.

Visual protective sheet can increase blink rate while playing a hand-held video game.

PURPOSE: To evaluate the effectiveness of a protective sheet in reducing eye strain caused by unnecessary light reflection on portable liquid crystal display panels while playing Game Boy (Nintendo, Kyoto, Japan). DESIGN: Nonrandomized clinical trial. METHODS: The blink rates of 24 normal volunteers were measured under relaxed conditions while viewing a portable liquid crystal display panel and playing Game Boy with and without the protective sheet of polyethylene terephthalate with antiglare coating for a total of 10 minutes each. RESULTS: The results showed a dramatic increase (from 5.6 +/- 3 to 9.1 +/- 4.9 [P <.0001]) in blinks/minute with use of the protective sheet. CONCLUSION: The protective sheet has shown the possibility of increasing the blink rate by making the screen easier to see.

Retinal detachments by squash ball accidents.

PURPOSE: To evaluate the characteristics of retinal detachments caused by squash ball accidents. METHODS: Twenty-six patients had a retinal detachment after a squash ball hit their eyes. RESULTS: Characteristics of the 26 eyes with retinal detachment were large retinal tears parallel to the corneoscleral limbus located close to the ora serrata usually in the temporal superior fundus quadrant (in 14 [54%] of the 26 eyes) and in the temporal inferior quadrant (in seven eyes [27%]); primarily intact vitreous with a traumatic avulsion of the vitreous base in approximately one half the patients; relatively slow progression of the retinal detachment; and additional damage to the choroid and retinal pigment epithelium in the posterior fundus. The patients were young and did not have severe myopia. Reattachment of the retina was achieved in 22 (85%) of the 26 patients. In 11 patients (42%), visual acuity outcome was 20/40 or better with best correction. CONCLUSIONS: Retinal detachments after squash ball accidents show different characteristics with worse prognosis than do ordinary rhegmatogenous detachments. Protective eyewear should be worn when playing squash.

Welding processes and ocular hazards and protection.

There are approximately 60 different forms of welding, but only six of these are commonly used. Shielded metal-arc or stick welding, gas metal-arc welding, and oxyacetylene welding are the most frequently used. All produce ultraviolet, visible, and infrared radiation at damaging levels. Conventional glass welding shields contain ultraviolet, visible, and infrared absorbers. Infrared absorbers, however, cause heating and secondary re-radiation. New polycarbonate lenses offer greater impact resistance, and have less tendency to welding spatter. Early abrasion-resistant and reflective coatings on plastics were ineffective. Thin layers of gold with proprietary coatings provide cool reflection and surface resistance. Thermal monitoring of welding indicated that these new shields reduce temperature rises above the ambient by 150% to 175% compared to green glass filter plates without interfering with the welder's vision.

Eye shield for patients undergoing laser treatment.

We developed a patient eye shield consisting of a sandwich of polymethylmethacrylate and tinfoil to provide corneal and retinal protection from inadvertent injury during argon, neodymium:YAG, or dye laser treatment. The shield was tested with argon, dye, neodymium:YAG and CO2 lasers. This new eye shield is safe, comfortable, and easy to clean and use.

Eye injuries due to tractor wheel explosion: report of two cases.

CASE REPORT: We describe 2 patients who sustained eye injuries when tractor wheels exploded while being inflated. Descriptions of ocular involvement from such accidents are rare in the literature. One of our patients experienced severe eye trauma requiring enucleation. In the second case, despite trauma to both eyes, 20/20 vision was recovered. COMMENTS: Injuries from exploding tires are compared to those seen in the context of air-bag deployment, and safety recommendations are discussed.

The risk of blood splash contamination during angiography.

Blood splash contamination of the conjunctivae or buccal mucosa may occur during angiography and angioplasty. Since there is a risk of contracting Hepatitis B or HIV via this route, staff should be aware of this potential source of infection. The use of protective masks and goggles or glasses should be considered. We have studied the risk of contamination by asking both the radiologist and angiography nurse to wear spectacles and disposable masks during 100 consecutive angiographic procedures. The number of splashes was counted at the end of each procedure. Blood splashes occurred in seven procedures and there was a total of 23 splashes during the study. In conclusion, we believe that there is a significant risk of conjunctival or mucosal contamination with blood during angiographic procedures and given the potential seriousness of transmission of Hepatitis B or HIV, radiologists and nursing staff must be aware of this risk.

Affect changes observed with right versus left lateral visual field stimulation in psychotherapy patients: possible physiological, psychological, and therapeutic implications.

Seventy psychotherapy patients were given two pairs of goggles each taped over to allow vision from only the left or the right lateral visual field (LVF and RVF). Sixty percent reported at least a one-point difference between visual fields on a five-point anxiety scale; 23% reported at least a two-point difference. Among 21 patients with major depression, 11 reported greater anxiety through the LVF, four reported greater anxiety through the RVF, and six reported no difference. Among 18 with posttraumatic stress disorder (PTSD), 10 reported greater anxiety from the RVF and four from the LVF, and four reported no difference. The absolute difference in anxiety ratings was significantly greater (P < .001) between the two pairs of experimental goggles than between two pairs of control goggles allowing monocular vision among 40 patients in whom the four pairs were tested. During a subsequent psychiatric interview, 40 of 49 patients who were responsive while using the experimental goggles manifested an intensification of their usual symptoms on one side and an alleviation on the other. The possible physiological, psychological, and therapeutic implications of these findings are discussed.

Types of gowns used in trauma and orthopaedic theatres.

Trauma and orthopaedic surgeons are at an increased risk of acquiring viral blood-borne infections during elective and especially trauma surgery. The British Orthopaedic Association (BOA) published guidelines in 1991 for the prevention of cross-infection between patients and staff. It was recommended that only waterproof gowns be used in orthopaedic and trauma theatres. The aim of this study was to determine the compliance with the BOA recommendations. A telephone survey of 79 hospitals in England shows that only a minority (41 per cent) of hospitals use waterproof gowns exclusively.
