Extracorporeal shock wave lithotripsy (ESWL) for urinary tract stones using Dornier MFL 5000, performed by the technician.

As the only lithotripsy centre at a University Hospital in the most crowded city of Turkey, we have a big number of patients with urinary stones. Between April 1990 and August 1993, 2680 sessions of treatment were done to 1257 renal units. Our study reveals that the results obtained by the performance of an experienced technician are just as reliable as those obtained by an experienced urologist.

Surgical residents and ultrasound technician accuracy and cost-effectiveness of ultrasound in trauma.

The purpose of this study is 2-fold: 1) to assess the accuracy of the Focused Abdominal Sonogram for Trauma (FAST) as an important evaluative tool for the trauma victim as compared with other objective testing resources (i.e., computerized axial tomography scan); and 2) to analyze the cost-effectiveness of FAST as performed by surgical residents as compared with ultrasound (US) technicians. FAST was performed on 650 trauma victims over a period of 12 months. Testing was completed in a trauma room of the emergency department by an US technician or a trauma surgical resident as determined by the availability of the US technician. Hypotensive patients required two FASTs to be completed for comparison of results. Persistent difficulty interpreting the FAST required the addition of a computerized axial tomography scan to help clarify the results. Statistical analysis was performed using chi2 and analysis of variance. False positive, false negative, and true positive, true negative, along with the accuracy of FAST were calculated as compared with other diagnostic testing. The finding indicated that FAST was both specific (99 per cent) and sensitive (68 per cent) in the sample used. Of the 650 patients receiving FAST, true negative was 95 per cent, true positive was 3 per cent as compared with false negative at 1 per cent, and false positive at 0.5 per cent. US technicians performed 81 per cent of the FASTs with an accuracy of 92 per cent. In comparison, surgical residents had a 92 per cent rate of accuracy in the remaining 19 per cent of the population. The mean accuracy of both was 94 per cent. Furthermore, FAST as performed by resident incurred a single fee of $88 for radiological readings as compared with $274 for an US technician fee plus the radiological reading fee of $88. FAST as performed by surgical residents is more cost-effective than FAST as performed by an US technician.

An outbreak of post-operative sepsis due to a staphyloccoccal disperser.

A staphylococcal disperser employed as a theatre technician appeared to have been the source of 11 cases of wound sepsis over a period of about 3 years. He was primarily a nasal carrier and after attempts to eradicate Staphylococcus aureus from his nose failed, his skin dispersal was controlled by daily washing with 4% chlorhexidine detergent ('Hibiscrub') and he was allowed to resume his theatre duties under careful bacteriological surveillance. Over the following 2 years 173 dispersal tests showed a mean dispersal of 1 . 7 c.f.u. per 2800 l air compared with a mean of 152 c.f.u. per 2800 l air in the mouth immediately preceding treatment and 55 c.f.u. per 2800 l in the period after cessation of treatment. One case of wound sepsis was attributed to the technician during the 2 years in which he received skin disinfection treatment.

Maintaining the surgical research facility: the role of the surgical technician.

Building a well-equipped surgical facility is only half the battle. By ensuring that these facilities and their equipment are kept clean and well maintained, and that clear and thorough documentation is kept, research staff can protect both the quality of their work and the well-being of their animal patients.

Attitudes and practices of New Zealand anaesthetists with regard to emergency drugs.

A postal survey of anaesthetists practising in New Zealand assessed practices with regard to the preparation of pre-drawn syringes of emergency drugs in theatre, and attitudes towards the drawing up of drugs by non-medically qualified assistants. Opinion and practice varied widely; a quarter of respondents routinely draw up such drugs and a third either never or very infrequently do so. The drugs most commonly drawn up in this way were suxamethonium, atropine, syntocinon, ephedrine and metaraminol. Providing anaesthesia single-handed, anaesthesia involving paediatric, obstetric or vascular cases, the use of major regional techniques and laryngeal mask anaesthesia were reported as factors which prompted a number of respondents to draw up one or more of these drugs. The majority (68.5%) had received no teaching on the issue and nearly all (83.5%) reported that there was no institutional policy in their workplace(s). "Syringe swap" or "wrong drug" errors related to such pre-drawn drugs were reported by 26.5%, while delay in drawing up a drug in an emergency was reported by 37%. Nearly all (98%) respondents believed that it was acceptable for an anaesthetic technician (or similar assistant) to draw up drugs in an emergency but only 14% approved of assistants drawing up drugs routinely. We conclude that there is no uniformity of opinion amongst New Zealand anaesthetists about which if any drugs should be pre-drawn for possible emergency use, and that few would endorse the drawing up of drugs by non-medically qualified assistants, except in emergency, or under other clearly delineated circumstances.

Prevalence of immunoglobulin G to Helicobacter pylori among endoscopy nurses/technicians.

The purpose of this study was to compare the prevalence of Helicobacter pylori (HP) seropositivity among gastroenterology nurses and technicians with that of the general population. Nurses attending the 1996 Indiana Society of Gastroenterology Nurses and Associates Spring and Fall Education Courses were asked to complete a checklist regarding employment, current symptoms, and use of universal precautions, and to have 3 ml blood drawn. These 138 blood specimens as well as 112 serum samples from generally age- and sex-matched blood donors (representing the general population) underwent qualitative HP antibody testing. Results showed that the prevalence of seropositivity for immunoglobulin G (IgG) antibody for HP among the gastroenterology nurses and technicians was 19 of 138 (13.8%), which was less than that of the blood donor control group, whose seropositivity was 20 of 112 (17.9%). However, this difference failed to reach statistical significance. Seropositivity tended to increase with age, but there was no association between clinical symptomatology and seropositivity. Likewise, there was no difference in seropositivity between nurses assisting with endoscopic procedures for more than 10 years and those assisting for less than 10 years. Although the differences were not significant, these findings refute those of an earlier study in which the researchers found 122 gastroendoscopists and endoscopy nurses significantly more likely to be positive for HP antibodies. Therefore, the findings reported here provide important information.

[Nursing auxiliaries and technicians and hospital infection control in surgical centers: myths and truths].

This analytical and descriptive study is aimed at detecting concepts that translate myths and truths on hospital infection among nursing auxiliaries and technicians at the surgical centers of three hospitals. The data collection instrument consisted of 28 affirmative statements (15 true and 13 false) encompassing factors related to the patient, the surgical team, the environment, and procedures. The statements contain a three-point scale (I agree, I am in doubt, I disagree). We received 72% of adequate answers and 28% of non-adequate, which indicates that perioperative nursing professionals have satisfactory knowledge of hospital infection control. In the items use of safety footwear, rings and other objects, hair as a pathogen, hand scrubbing, use of humid gown and surgical area, infected surgery and cleaning routine, occupational diseases, hospital infection, surgical site infection and surgery time we were able to detect myths and rituals about infection control, which are mainly related to the culture of those who practice them, thus perpetuating resistance to change.

[Cost analysis of intraoperative neurophysiological monitoring (IOM)].

INTRODUCTION: A number of studies demonstrate that a significant reduction of postoperative neurological deficits can be achieved by applying intraoperative neurophysiological monitoring (IOM) methods. A cost analysis of IOM is imperative considering the strained financial situation in the public health services. MATERIAL AND METHODS: The calculation model presented here comprises two cost components: material and personnel. The material costs comprise consumer goods and depreciation of capital goods. The computation base was 200 IOM cases per year. Consumer goods were calculated for each IOM procedure respectively. The following constellation served as a basis for calculating personnel costs: (a) a medical technician (salary level BAT Vc) for one hour per case; (b) a resident (BAT IIa) for the entire duration of the measurement, and (c) a senior resident (BAT Ia) only for supervision. RESULTS: An IOM device consisting of an 8-channel preamplifier, an electrical and acoustic stimulator and special software costs 66,467 euros on the average. With an annual depreciation of 20%, the costs are 13,293 euros per year. This amounts to 66.46 euros per case for the capital goods. For reusable materials a sum of 0.75 euro; per case was calculated. Disposable materials were calculate for each procedure respectively. Total costs of 228.02 euro; per case were,s a sum of 0.75 euros per case was calculated. Disposable materials were calculate for each procedure respectively. Total costs of 228.02 euros per case were, calculated for surgery on the peripheral nervous system. They amount to 196.40 euros per case for spinal interventions and to 347.63 euros per case for more complex spinal operations. Operations in the cerebellopontine angle and brain stem cost 376.63 euros and 397.33 euros per case respectively. IOM costs amount to 328.03 euros per case for surgical management of an intracranial aneurysm and to 537.15 euros per case for functional interventions. Expenses run up to 833.63 euros per case for operations near the motor cortex and to 117.65 euros per case for intraoperative speech monitoring. DISCUSSION: Costs for inpatient medical rehabilitation have increased considerably in recent years. In view of the financial situation, it is necessary to reduce postoperative morbidity and the costs it involves. IOM leads to a reduction of morbidity. The costs for IOM calculated here justify its routine application in view of the legal and socioeconomic consequences of surgery-related neurological deficits.

Radiation hazard to operating room personnel during operative cholangiography.

During operative cholangiography, the surgeon and other operating room personnel are exposed to scattered radiation and its potential hazards. It was determined that a surgeon standing at the side of the patient during cholangiographic filming would receive 3.2 mR per film. Exposure would be only 0.5 mR per film if the surgeon stepped back 75 cm (2.5 ft) from the patient. This simple measure would reduce the monthly exposure of a surgeon who performs four cholangiograms per week from approximately 205 to 32 mR. The use of the new electronic video-disc recording systems and lead aprons can substantially reduce the amount of radiation exposure related to fluoroscopy. The prudent surgeon, recalling that no level of radiation may be totally safe, should use techniques that provide maximal protection for himself and all operating room personnel during performance of operative cholangiography.

DNA single-strand breaks in peripheral lymphocytes of clinical personnel with occupational exposure to volatile inhalational anesthetics.

The rates of DNA single-strand breaks in peripheral lymphocytes of 41 persons administering anesthesia daily and 44 control persons were determined by nucleoid sedimentation. There is a significantly higher rate of DNA single-strand breaks in nonsmoking anesthesia persons than in nonsmoking control persons (P < 0.01). Smoking anesthesia persons and smoking control persons presented increased rates of DNA single-strand breaks. Nonsmoking nurse anesthetists showed an insignificantly higher rate of damage than nonsmoking anesthesiologists. DNA single-strand breaks indicate damage before the start of DNA repair. Therefore, detected DNA single-strand breaks may be reversible. As not every DNA repair is perfect, increased rates of DNA single-strand breaks may possibly lead to irreversible DNA damage.
