ABSTRACT

El estudio de gases en sangre involucra pruebas relacionadas con el equilibrio ácido-base y estado de oxigenación (pH, pO2, SO2, pCO2, HCO3 -). Además, en los equipos multiparamétricos se realizan otras determinaciones (mediciones relacionadas) como: Na+, K+, Cl-, Ca2+, glucosa y lactato. El objetivo de este trabajo fue comparar los resultados de medición de dos tipos de recipientes (tipo 2: jeringa preparada en el laboratorio con heparinato de Na+ líquido diluido y tipo 3: microtubo con heparinato de Li líquido) contra el recipiente recomendado por el CLSI en su guía 46-A2 (tipo 1: jeringa con heparinato de Li liofilizado balanceado con zinc). El análisis se hizo desde un punto de vista estadístico y clínico para establecer la posibilidad de usar indistintamente estos tres tipos de recipientes. Se analizaron un total de 254 muestras. Para evaluar la aceptación clínica de los resultados se tomó como estándar de calidad la variabilidad biológica. No se encontraron diferencias clínicamente significativas en los analitos del recipiente tipo 2 respecto del tipo 1, excepto para Ca2+. Se rechazaron desde el punto de vista clínico varios analitos del recipiente tipo 3. En conclusión, el uso del recipiente tipo 3 fue inapropiado. Sin embargo, el recipiente tipo 2 sería apto para el análisis de este tipo de muestras.


Blood gas analysis involves tests related to the acid-base balance and oxygenation state (pH, pO2, SO2, pCO2, HCO3 -). In multiparametric equipment, some ion and metabolite (related measurements) are performed: Na+, K+, Cl-, Ca²+, glucose and lactate. The objective of this study was to compare two types of containers (type 2: syringe prepared in the laboratory with diluted liquid sodium heparinate and type 3: microtube with liquid lithium heparinate) against the container recommended by CLSI in its guide 46-A2 (type 1: syringe with lyophilized lithium heparinate balanced with inc). The analysis was made from a statistical and clinical point of view to establish the possibility of indiscriminately using these three types of containers. A total of 254 samples were analyzed. To establish the clinical acceptance of the results, the biological variability quality standard was used. No clinically significant differences were found in the analytes of the type 2 container compared to type 1, except for Ca+. Several analytes of the type 3 container were rejected from the clinical point of view. In conclusion, the use of the type 3 container is inappropriate; however, the type 2 container would be suitable for the analysis of this type of samples.

ABSTRACT

Until now, automatic contrast agent injector syringes licensed for consecutive one-time use have been employed with a number of patients. In 2016, regulation of automatic injector syringes ensured their single use, and reuse was strictly limited by law. However, this regulation creates the social problems of rising medical costs and resource waste. Many doctors are not significantly concerned about infection from contrast agent injection because the needle and connection lines on the patient side are set up for single use, the connections between syringes and contrast agents are reusable, and there are no reports of excessive infection. However, infection can nevertheless occur with injection of contrast agents. We should therefore implement the correct and safe use of contrast agents and take precautions against infection. To prevent infection due to contrast agents, syringes and connection lines for injection of such agents should be used once per patient, or multi-use licensed products should be used. In the latter case, reverse flow prevention filters must be used on the patient's side.

ABSTRACT

La presente comunicación tiene como objetivo informar sobre la cantidad de material que se pierde junto con las puntas dispensadoras descartables durante el uso de materiales endodónticos contenidos en jeringas y comprobar si esa cantidad es significativa en comparación con el contenido total original (15 g). Se procedió a pesar en una balanza de precisión 12 puntas dispensadoras descartables vacías, pertenecientes a dos materiales de uso endodóntico: 2Seal EasyMix (VDW) y Activa BioActive-Base/Liner (PulpDent Corp.). La sumatoria del peso (masa) en las 12 puntas pertenecientes a cada uno de los materiales ensayados fue considerada como peso total de las puntas vacías. Posteriormente, las puntas se llenaron completamente con los materiales, se almacenaron durante 48 horas para permitir el fraguado y finalmente se las pesó nuevamente. La diferencia entre el peso de las 12 puntas vacías y llenas fue considerada como la cantidad de material remanente que se descarta con ellas. La diferencia entre los totales de masa contenida en las puntas llenas de cada material y el contenido original de las jeringas representó la proporción de material que se descarta sin haber sido utilizado. Cuando el porcentaje de material descartado fue menor o igual al 20%, el resultado se consideró aceptable. Se observó que la proporción de ambos materiales fue mayor al 20% (2Seal EasyMix=44,36%; Activa BioActive-Base/Liner=36,87%). Se concluyó que el empleo de materiales endodónticos contenidos en jeringas dispensadoras produce la pérdida de una importante proporción de material durante los procedimientos operatorios (AU)


In order to inform about the amount of material that is lost along with the disposable dispensing tips during the use of endodontic materials contained in deliver syringes and check if that amount is significant compared to the total original content (15 g) of them. 12 empty disposable dispensing tips belonging to two endodontic materials: 2Seal EasyMix (VDW) and ActivaBioactive Base/liner (PulpDent Corp.), were weighed on a precision scale. The sum of the weight (mass) of each of the 12 tips belonging to each of the materials tested was considered as the total weight of the empty tips. Subsequently, the tips were completely filled with the materials, stored for 48 hours to allow them to set and finally weighed again. The difference between the weight of the 12 empty and full tips was considered as the amount of material remaining within them that is discarded. The difference between the total mass contained in 12 filled tips of each material and the original syringe content represented the proportion of material discarded without being used. It was considered that if the % of discarded material was ≤20% this would be considered acceptable. It was observed that the proportion of both materials was >20% (2Seal EasyMix = 44.36%; ActivaBioactive Base/liner = 36.87%). The use of endodontic materials contained in dispensing syringes causes the loss of a significant proportion of material during the operative procedures (AU)

ABSTRACT

BACKGROUND: Inaccuracies associated with target-controlled infusion (TCI) delivery systems are attributable to both software and hardware issues, as well as pharmacokinetic variability. However, little is known about the inaccuracy of the syringe pump operating in TCI mode. This study aimed to evaluate the accuracy of the TCI pump based on international standards.METHODS: A test apparatus for accuracy evaluation of a syringe pump (PION TCI®, Bionet Co. Ltd.) was designed to apply the gravimetric method. Pump accuracy was evaluated in terms of deviation defined by the following equation: infusion rate deviation (%) = (Rate(mea) − Rate(est)) / Rate(est) × 100, where Rate(mea) is the infusion rate (ml/h) as measured by the gravimetric system, and Rate(est) is the infusion rate (ml/h) as estimated by the pump. An infusion rate representing TCI mode was determined from previous clinical trial data which evaluated the predictive performance of the pharmacokinetic model. The PION TCI pump used in that clinical trial was used to evaluate accuracy of the syringe pump. The distribution of infusion rates obtained from the clinical trial was calculated, and the median value of the distribution was determined as the representative value.RESULTS: The representative infusion rate representing TCI mode was 31 ml/h, at which the infusion rate deviation was 4.5 ± 1.6%.CONCLUSIONS: The inaccuracy of the syringe pump contributing to TCI system inaccuracy is insignificant.

ABSTRACT

PURPOSE: Fine-needle aspiration biopsy (FNAB) can be used to diagnose thyroid cancer and other tumors. Although FNAB without negative pressure (FNAB−P) reduces the risk of blood contamination, FNAB with negative pressure (FNAB+P) increases the sensitivity of the biopsy results. Therefore, we performed a randomized study of FNAB with or without negative pressure to identify the better diagnostic method. METHODS: Between March 2016 and February 2017, 172 consecutive patients were enrolled to investigate >0.5 cm nodules with indeterminate or suspicious malignant features. Patients were randomly assigned to the FNAB+P group (a 50 mL syringe was used to provide negative pressure) or to the FNAB−P group (passive collection of blood in the needle's hub). The 2 methods' diagnostic adequacy and quality were evaluated using an objective scoring system. The study's protocol was registered with the World Health Organization Clinical Research Information Service (http://cris.nih.go.kr/cris, KCT0001857). RESULTS: The patients were randomly assigned to the FNAB+P group (n = 86) or the FNAB−P group (n = 86). There were no significant intergroup differences in nodule position, size, age, consistency, calcification, BRAF mutation, or pathology. Evaluation of diagnostic adequacy parameters revealed no significant differences in background blood/clot (P = 0.728), amount of cellular material (P = 0.052), degree of cellular degeneration (P = 0.622), degree of cellular trauma (P = 0.979), or retention of appropriate architecture (P = 0.487). Furthermore, there was no significant intergroup difference in the diagnostic quality (P = 0.634). CONCLUSION: This prospective randomized study failed to detect significant differences in the diagnostic adequacy and quality of FNAB with or without negative pressure. Therefore, the examiner may select whichever FNAB method they prefer.

ABSTRACT

PURPOSE: The aims of this study were to evaluate the dentist's awareness and the actual status of infection control of noncritical dental instruments. MATERIALS AND METHODS: 40 dental clinics in Daejeon, South Chungcheong, North Chungcheong and North Jeolla provinces were surveyed. The questionnaire was delivered to the dentists belonging to those clinics, and the awareness and the practice of infection control were examined. The microbial contamination on the surface of five noncritical instruments (impression gun, light curing unit, 3-way syringe, shade guide, and dental floss dispenser) used by them was measured with an ATP luminometer. Correlation analysis between the awareness and the actual state of infection control was conducted. RESULTS: Awareness and frequency of infection control was highest in the 3-way syringe. Surface disinfection using disinfectant was most frequent in all instruments. 3-way syringes and shade guides were less contaminated than impression guns, light curing units, and dental floss dispensers. CONCLUSION: 3-way syringes had a significant correlation between user awareness of infection control and surface contamination, and the higher awareness, the lower the contamination measurement was shown.

ABSTRACT

Barium sulfate is commonly used to prepare contrast media for videofluorograpy. The flow characteristics of thickened liquids formulated for oropharyngeal imaging are known to be greatly affected by the addition of barium. In this study, thickened barium liquids were prepared by mixing a commercial xanthan gum (XG)-based thickener (Visco-up®) at different concentrations (0.1%–3.0%) with barium powder (Baritop HD®), and differences in the viscosity between thickened non-barium and thickened barium liquids were investigated. In addition, the thickness levels of thickened barium liquids, which are based on the National Dysphagia Diet (NDD) and International Dysphagia Diet Standardization Initiative (IDDSI) guidelines, were classified by measuring the viscosity (NDD) and gravity flow through a syringe (IDDSI) with 0.1%–3.0% thickener concentrations. The apparent viscosity (η(a),₅₀) values of thickened barium liquids were much higher than those of thickened non-barium liquids, indicating that the addition of barium to the XG-based thickener resulted in further thickening. Standard recipes for preparing thickened barium liquids with desirable thickness levels were also established, showing the different thickener concentrations corresponding to the different NDD and IDDSI levels.

ABSTRACT

STUDY DESIGN: Retrospective cohort study. PURPOSE: To investigate the correlation between the syrinx morphology and neuropathic pain caused by syringomyelia associated with Chiari I malformation. OVERVIEW OF LITERATURE: Neuropathic pain caused by syringomyelia is refractory and markedly impairs the patient. METHODS: We examined 24 patients with neuropathic pain caused by syringomyelia associated with Chiari I malformation. We statistically analyzed the illness duration and age at surgery between patients with and without neuropathic pain. Additionally, we classified the morphology of the syringes into deviated (D), enlarged (E), central (C), and bulkhead (B) types using T2-weighted axial imaging. Moreover, we investigated the correlation between syrinx morphology and neuropathic pain. A Mann–Whitney U-test was performed to compare between the presence or absence of neuropathic pain and the presence or absence of type D syringes. RESULTS: The median age at surgery was 27.5 years, and the median illness duration was 24 months. Among the 24 patients, 11 had preoperative neuropathic pain, one of which was free of neuropathic pain during the final follow-up period. Among patients with neuropathic pain, the syringes’ preoperative morphology was type D in nine patients and types E and C in one patient each. No patient exhibited type B morphology. Among patients without neuropathic pain, the preoperative morphology of the syringes was type D in three patients, type E in seven patients, and types C and B in two patients each. For types D and E, a correlation between neuropathic pain and syrinx morphology was observed. Moreover, type D was associated with significant neuropathic pain in both preoperative and postoperative states. CONCLUSIONS: This study showed a correlation between the morphological features of the syringes and the occurrence of neuropathic pain in patients with syringomyelia associated with Chiari I malformation.

ABSTRACT

PURPOSE: The most common risk factor for fecal incontinence (FI) is obstetric injury. FI affects 1.4%–18% of adults. Most patients are unaware when they are young, when symptoms appear suddenly and worsen with aging. Autologous fat graft is widely used in cosmetic surgical field and may substitute for injectable bulky agents in treating FI. Authors have done fat graft for past several years. This article reports the effectiveness of the fat graft in treating FI and discusses satisfaction with the procedure. METHODS: Fat was harvested from both lateral thighs using 10-mL Luer-loc syringe. Pure fat was extracted from harvests and mixed with fat, oil, and tumescent through refinement. Fats were injected into upper border of posterior ano-rectal ring, submucosa of anal canal and intersphincteric space. Thirty-five patients with FI were treated with this method from July 2016 to February 2017 in Busan Hangun Hospital. They were 13 male (mean age, 60.8 years) and 22 female patients (mean age, 63.3 years). The Wexner score was checked before procedure. We evaluated outcome in outpatients by asking the patients. For 19 patients we checked the Wexner score after procedure. RESULTS: Symptom improved in 29 (82.9%), and not improved in 6 (17.1%). In 2 of 6 patients, they felt better than before procedure, although not satisfied. No improvement in 4. Mean Wexner score was 9.7 before procedure. There were no serious complications such as inflammation or fat embolism. CONCLUSION: Autologous fat graft can be an effective alternative treatment for FI. It is safe and easy to perform, and cost effective.

ABSTRACT

PURPOSE: Complete removal of air bubbles from balloons for neurovascular angioplasty is cumbersome. We compared the preparation difficulty, air removal efficiency, and air collection pattern of six different balloon catheter preparation methods to propose a better preparation method for both initial and second balloon uses, especially for small-profile angioplasty balloon catheters. MATERIALS AND METHODS: A total of 18 neurovascular angioplasty balloon catheters with nominal diameters of 2 mm were prepared to test six different preparation methods: the instruction for use method (method A), simplified method using a syringe (method B) and four newly devised preparation methods using inflating devices (methods C–F). Serial radiographs were obtained while the balloons were gradually inflated. We measured the time for each preparation and the bubble number, analyzed their distribution in the balloon, and calculated the contrast filling ratio (contrast filling area/total balloon area) for initial and second ballooning. The whole process was repeated three times. RESULTS: The preparation time varied widely (11.5 seconds [method D] to 73.3 seconds [method A]). On initial inflation, the contrast filling ratio at 8 atm was the highest (100%) with methods A and F. On second inflation, the ratio was again highest with method A (99.5%), followed by method F (99.2%). Initial ballooning tended to show a uniform pattern of single bubble in the distal segment of the balloon; in contrast, second ballooning showed varying patterns in which the bubbles were multiple and randomly distributed. CONCLUSION: None of the six methods were able to completely exclude air bubbles from the balloon catheters including the second ballooning; however, the method of repeating aspiration with high-volume inflating device (method F) could be a practical option considering the simplicity and efficiency of preparation.

ABSTRACT

Abstract The objectives of this double-blind randomized clinical trial were to compare (a) the clinical times and (b) the occurrence and severity of postoperative sensitivity, of posterior restoration that used a universal adhesive, in a self-etch or selective enamel-etching technique, along with incremental or bulk-fill composites (presented in syringes or capsules). A total of 295 posterior restorations were placed according to the following groups: SETB - self-etch/bulk-fill in syringe; SETC - self-etch/bulk-fill in capsules; SETI - self-etch/incremental; SEEB - selective enamel-etching/bulk-fill in syringe; SEEC - selective enamel-etching/bulk-fill in capsules; and SEEI - selective enamel-etching/incremental. Clinical time was assessed by a reason (s/mm3) between the total volume of resin inserted and the total time required to perform the restorations. Postoperative sensitivity was evaluated using two scales (Numeric Rating Scale and Visual Analogue Scale). Mean clinical time results, analyzed by Wald's Chi-square, showed significant statistical differences among all groups (p<0.001), indicating that the restorative strategy affected the time required for the restoration. A generalized estimating equation model statistical analysis, performed to compare postoperative sensitivity, showed that neither the restorative technique, the adhesive strategy nor the presentation mode of the bulk-fill composite affected the overall risk of postoperative sensitivity (4.06 [2.22-6.81]). The use of bulk-fill composite, presented in capsules or syringes, is less time consuming and does not increase the risk or intensity of postoperative sensitivity relative to the traditional incremental technique.

ABSTRACT

BACKGROUND: Previous studies have shown that sequential intrathecal injection of fentanyl and hyperbaric bupivacaine for cesarean section (CS) anesthesia provides a superior anesthetic effect than use of bupivacaine alone, and prolongs postoperative analgesia. Herein, we investigated whether rapid intrathecal injection of fentanyl followed by slow injection of hyperbaric bupivacaine affects the duration of postoperative analgesia, the effectiveness of anesthesia, and hemodynamic status. METHODS: Fifty-six parturients with American Society of Anesthesiologists physical status I or II, aged 18–40 years, and scheduled to undergo elective CS were randomly assigned to 2 groups of 28 patients each. The normal sequential group received sequential intrathecal injections of fentanyl and hyperbaric bupivacaine at the same rate, each with a 5 ml syringe. The rapid sequential group received a rapid intrathecal injection of fentanyl with an insulin syringe, followed by a slow injection of hyperbaric bupivacaine with a 5 ml syringe. The onset of sensory block, the timing of the first rescue analgesia, the doses of rescue analgesics, the degree of postoperative pain, the onset and duration of motor block, the incidence and duration of hypotension, and spinal anesthesia-related complications were recorded. RESULTS: While both approaches had comparable spinal anesthesia-related complications, incidence and duration of hypotension, and doses of ephedrine, the rapid sequential group exhibited a more rapid onset of sensory block, a higher sensory level, and more prolonged postoperative analgesia. CONCLUSIONS: Rapid sequential injection of fentanyl and hyperbaric bupivacaine produced superior anesthesia and more prolonged postoperative analgesia than sequential injections of both at the same rate.

ABSTRACT

BACKGROUND AND OBJECTIVES: To determine the efficacy of filling the external auditory meatus with 1% clotrimazole at a single visit for the treatment of otomycosis. SUBJECTS AND METHODS: This prospective study included 40 patients who were referred to our clinic with complaints of ear itching, pain, and fullness, and were diagnosed with unilateral otomycosis. After cleaning the mycotic hyphae from the external auditory meatus, the ear canal was filled with 1% clotrimazole, using an intravenous catheter and syringe. The patients received follow-up examinations on post-treatment days 7, 15, and 45. RESULTS: The follow-up otomicroscopic examinations revealed that 95% of the ear canals were entirely clean and that all symptoms had resolved. The post-treatment scores of pain, aural fullness and itching were significantly lower than the pre-treatment scores (p < 0.01). CONCLUSIONS: Filling the external auditory meatus with 1% clotrimazole at a single visit is an easy, efficient, and cost-effective treatment for otomycosis. Additionally, high patient compliance makes this treatment superior to long-term topical therapy.

ABSTRACT

Objective of this study was to compare the color stability, mechanical and chemical properties of three different types of temporary crown resins. Commercially available powder-liquid (Group PL), light-cured (Group LC) and auto-mix syringe (Group AM) types' temporary crown resins were used as experimental groups for each of the evaluation. All the test groups were evaluated after 1 day and 7 days of immersion in various staining solutions. The colors of all groups before and after storage in the staining solutions were measured by a spectrophotometer based on CIE Lab system, and the color differences (ΔE(*)) thereby calculated. Micro hardness test was performed before water storage and aging after 7 days at 37 ℃. In addition, flexural strength, water sorption and solubility tests were performed according to international standard, ISO 10477. All experimental groups showed significant color change in staining solutions when compared to those stored in the control solution (distilled water) (p PL > LC (p<0.05). Water sorption and solubility increased in the following order: AM < PL < LC (p<0.05). The results of this study would provide useful information when choosing temporary crown resin types in various clinical situations.

ABSTRACT

BACKGROUND: Carrying epinephrine can save lives in patients with anaphylaxis. The feature of epinephrine in prefilled syringe that commonly prescribed in Thailand may influence the willingness to carry. However, the rates of carrying prefilled syringe epinephrine are unknown in children with history of food-induced anaphylaxis. OBJECTIVE: To determine the rate of epinephrine carrying in children with history of food-induced anaphylaxis and factors influencing the decision to use the devices. METHODS: A cross-sectional study was conducted by performing the structured interview in the parent(s) who were the main caregiver of the children with history of food-induced anaphylaxis. RESULTS: The parents of 99 children (male, 50.5%) were interviewed. The median age of the child was 11 years old (range, 9 months to 18 years). Rate of carrying epinephrine was 84.7% (always 57.6%, some occasions 27.2%). The most common reason for not carrying was the thoughts that the children could avoid the food allergens. The first-aid facility at school was available in 48.3%. Rate of carrying epinephrine tended to be lesser in children attend the schools without first aid facility (p = 0.053). Forty-one patients had relapsing episodes, 34 (82.9%) had epinephrine carried, and 20 (58.8%) injected the epinephrine. The most common reason for not using epinephrine despite carrying was that they were afraid of getting injection (28.5%). CONCLUSION: Most children with history of food-induced anaphylaxis carried epinephrine, but only half used it at the episodes. Interventions to promote epinephrine-carrying and injection training are needed in our setting.

ABSTRACT

PURPOSE: The aim was to describe our preliminary experience performing testicular fine-needle aspiration (TEFNA) with a larger needle in infertile patients with obstructive azoospermia, and to provide a systematic literature review of the different testicular sperm aspiration techniques, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement recommendations. MATERIALS AND METHODS: We prospectively collected data between March 2017 and June 2018. All men underwent bilateral TEFNA under analgo-sedation, using a larger disposable 18-gauge butterfly needle with 60 mL Luer-Lock syringe attached to it. RESULTS: Thirty consecutive patients were enrolled. Median operative time was 16 minutes (interquartile range [IQR]: 12–30 minutes). No intraoperative complications occurred. Two/thirty patients (6.7%) reported postoperative adverse events: 1 patient had prolonged orchialgia, 1 patient presented scrotal hematoma. Successful sperm retrieval was found in 28/30 cases (93.3%). Median sperm concentration was 0.05 ×106/mL (IQR: 0.001–0.1 ×106/mL). Median total sperm motility was 10% (IQR: 0%–15%). In 20/30 men (66.7%) sperm retrieved was used for fresh intracytoplasmic sperm injection cycle, in 8/30 (26.7%) sperm cryopreservation was necessary, because on the day of sperm retrieval the female resulted not responder to ovarian stimulation. In this cases mean number of 3 (IQR: 1–4) bio system straws was cryopreserved. CONCLUSIONS: TEFNA with 18-gauge needle proved to be a feasible, safe and effective treatment, even if future prospective studies will be addressed to clarify what type of azoospermia benefits from this procedure, and if a larger needle permits to improve Assisted Reproductive Technologies (ART) outcomes.

ABSTRACT

OBJECTIVES: An automatic needle destroyer (ANDY) was developed to prevent needlestick injuries, and usability tests were conducted in several hospitals. The addition of extra features to the ANDY is in progress, such as data collection and automatic identification of used syringes. Thus, this report describes how the ANDY can be used to track the data of used syringes. METHODS: The motor torque required for barrel separation differs according to syringe diameters. By monitoring the electric current which is consumed for the motor torque, the type of syringe can be identified. Twelve prototypes were produced, and five usability tests were conducted in hospitals. RESULTS: After use, a syringe is inserted into the proposed device, and the needle portion is then cut and separated from the syringe body (barrel) and discarded. The needles are collected in a sharps container for hygienic disposal, and the barrel is dropped into a general medical waste container. CONCLUSIONS: The ANDY can be used to track the syringe used for each patient. The barcode can be read while the syringe rotates in the main body of the ANDY with a built-in omnidirectional scanner. Collection of information during syringe disposal can facilitate stock management. This system could also be extended to other types of consumable medical devices, although it would still be a challenge to differentiate each medical device.
