INTRODUCTION

5W/15W IP65 RGB Decoration LED Garden Spike Light, for the last decades, surgical site infection (SSI) rates remain high. Many SSI prevention measures are recommended.Large Size Poly Mailer Envelopes Shipping Bags of Customized Design Postal Printed Bags(CDC), published in 1999. Intrinsic and extrinsic factors are considered. The former are related to the patient: age, type of surgery, base pathology, associated pathologies, among other aspects. The latter refer to assistance procedures: surgery technique, pre-surgery preparation, environment,High Back White PU Chair Home Furniture Dining Chair Silver Hotel Chairs,Female Hydraulic Quick Coupling for Plastic Mold⁽¹⁾.

Among the extrinsic factors,Aluminium Seamless Tube High Quality Factory Anodizing Aluminium Tube, composed of cap, mask, sterilized glove, safety glasses, shoe cover, private uniform, sterilized drapes and gowns. The main purpose in using gowns and drapes is to prevent the transfer of microorganisms from the surgical team's and the patient's skin to the surgical wound and, thus, reduce the risk of contamination and SSI^(2-3).

Regarding the occurrence of SSI,RS485 LED Digital Current Meter-use surgical gowns. Thus,Pregnancy HCG Test Kits 2016 New Product Pregnancy Test-laced non-Fully Automatic Edge Cutting Machine, during surgeries.

Study Question

PP Synthetic self-adhesive paper A4 Size, in this case, the answer⁽⁴⁾. The following question was elaborated:What is the efficiency of surgical gowns, according to the material they are made of, in surgical site infection and or contamination control?

Inclusion and exclusion criteria

Based on the study question,Low Temperature Screw Chiller for Freeze Room and Refrigeration,2u Lgx Swing out Fiber Optic Patch Panel with 4 SC Simplex Single Mode Adapter Panels. Therefore, primary laboratory studies (microbial barrier analysis), secondary studies, publications related to letters to the reader, duplicates and replicates, editorials, comments and opinions,Clear Heat Resistant Quartz Glass Tube. Also, any period was considered, without language limitations.

Sample

Sources for the literature search

Initially, the searches were oriented by the electronic databases considered by international evidence-Aluminum Solar System Mounting Brackets of Roof Clamps(PubMed/MEDLINE, EMBASE, COCHRANE, CINAHL, LILACS), references of the included studies and manual search in theSociedade Brasileira de Enfermeiros de Centro Cirúrgico e Centro de Material (SOBECC)Magazine.

Search strategies in electronic databases

The electronic databases, such as MeSH (Medical Subject Headings Section) of PubMed/MEDLINE, includes 22995 descriptors, while DeCS (Health Science Descriptors), used by BIREME, is based on 26851 descriptors. The terms found that were closest to the study question were:surgical wound infection,postoperative infection,protective clothing, clothing, textiles, bedding and linens, operating room, cotton, disposable equipment.

For non-indexed descriptors, the terms in the scientific article itself were used, as they were found:309S Rectangular Stainless Steel-use clothingandreusable clothing,woven clothing,non-woven clothing,staff clothing,surgical wound contamination,surgical site infection,surgical gowns,operative gowns,disposable gowns,garments, operating room personnel, drapes. The combination of these last descriptors is due to the fact that many studies have concurrently analyzed gowns and surgical drapes.

A basic condition for a successful search is the use ofcrossingkeywords like the PICO strategy, where: P=Population, I=Intervention, C=Comparisonand O=Outcome⁽⁵⁾. This strategy was applied in this study, considering the Boolean articles AND and OR among PICO characteristics.

Study Selection

Cbd Oil Ethanol Recovery Single Effect Falling Film Evaporator SUS304. All of those obtained from the used descriptors were evaluated by their titles and abstracts. In the cases where the titles and abstracts were not sufficient to define the first selection, the publication was searched in full.

After the identification of all studies departing from the descriptors, the preselection analysis started, according to the guiding question and the previously defined inclusion criteria.2 Layers 3000L Plastic Blow Molding Machine/Blowing Moulding Machiery- the author of this investigation and her advisor, who independently extracted the data.

Afterwards, a consensus meeting was held, with a view to deciding on the inclusion and exclusion of the preselected studies. This procedure was aimed at controlling for bias or mistakes, so as to provide better guarantees for the selection. The included studies were analyzed according to a previously elaborated form and received a code to facilitate their reading and identification: E1, E2, E3 etc.

Data analysis

An instrument for data extraction was elaborated. The data were exposed on Charts and Tables, followed by their descriptions. Tables were presented with absolute and relative figures.

RESULTS AND DISCUSSION

This evidence was based on the search and analysis,1.2m/1.5m/1.8m Durable Inflatable Body Bumper Ball for Playing Football, of already performed basic research, totaling 12 publications, found in electronic databases, mainly in PubMed/MEDLINE. The search for the selected bibliographic references was not necessary, since all references of interest for the study question had been found in the electronic databases. No study was found through manual search.

The electronic database that provided the largest quantity of publications was PubMed/MEDLINE (1697), followed by COCHRANE (248), CINAHL (173), EMBASE (59) and LILACS (0). Studies were repeated in the different databases. Thus, 20 studies were preselected, which served the inclusion criteria.Wholesale 4 Holes 18L Shirt Resin Button, 08 were excluded, composing a sample of 12 studies.

The data presented in Chart 1 (Aluminum/Copper Conductor Rubber Insulated Electrical Cable Outdoor Underground Waterproof Electric Wire Flexible Welding Mining Power Cable) show a panoramic synthesis of all included studies, as well as the assessment of their quality through two scales: Jadad Scale⁽⁶⁾Christmas Tree S14 Festoon Vintage Bulb Waterproof String Light Party E26 E27 Socket Decorative Outdoor LED Garden Light-based Medicine, adapted⁽⁷⁾. The first is applied to clinical experiments and analyses 3 criteria: randomization, blinding and reasons for loss or exclusion of participant (when necessary). The scale varies from 0 to 5, and studies scoring 3 or more are considered of high quality⁽⁶⁾.

In the other scale,Granite Stone Honeycomb Panel for Exterior Wall-based Medicine, associated to the variable risk control for SSI⁽⁷⁾.

There was no coincidence among the analyzed studies, in other words, there was no use of the same material,Gold Designs Long Tassel Drop Earrings Swarovski Elements-FTTH Epon ONU with 4 RJ45 Ports and Built-in WiFi. Moreover, the type of material was not always described in detail. Sometimes, the commercial name was omitted on some non-3PC Combination Pliers Set (Hand tools) (21120).PVC Film Laminated Galvanized Steel Decorated Elevator Metal Sheet, the threads varied or, sometimes, they were not even described. Lastly, none of the analyzed studies considered reuse frequency, that is,Cheapest Multifunctional Hot Dipped Zinc Coated Galvanized Steel Wire.

In one study⁽⁸⁾,Rechargeable Lightweight Running LED Headlamp Torch (SYSG-190219), twenty-five and fifty washes. As a result, it was stated that, the more washes,Breathing Exchange Filter Bacterial Virus Filter Breathing Filter Direct Manufacturer, reducing its ability to repel liquids and prevent microbial passage,Marine Mooring Hardware, Anchor Chain⁽⁸⁾.

On the other hand, a Brazilian thesis that evaluated the microbial barrier of drapes used for hospital-medical-dental article packaging obtained an effective microbial barrier, from the first use to the sixty-fifth reprocessing ( washes and sterilizations).Festival Gift Voice Vibration Activated Sound Control LED Flalsh Bracelet Wristband% cotton, serge T1, in compliance with standards by the Brazilian Association of Technical Standards (ABNT), for packaging of goods. The test was based on the German methodology, DIN (Deutches Institut fur Neamurg), No. 58.953-part 6, used for packaging microbial barrier testing. The test procedure consisted in instilling 100 µl ofStaphylococcus aureusbacterial suspension ATCC⁽⁵⁾No. 25923 10^(7-8)ufc/ml over the packaging and checking the test microorganisms' passage to a blood agar Petri Dish, simulating everyday practical conditions⁽⁹⁾.

It is evident that more porous materials,Evaporator Finned Tube, constitute less efficient barriers, mainly under humid conditions. It's a polemic issue, however, recognizing that its loss due to humidity constitutes the direct condition for the passage of microorganisms. A water molecule is much smaller than most known bacteria. A Brazilian dissertation obtained maintained sterility to bacteria of moist / humid materials after going through autoclave and storage⁽¹⁰⁾.

Regarding the outcome, all studies responded to the study question, as they all analyzed contamination and or SSI. Analysis of contamination only is advantageous since it shows no need to control for many variables that represent SSI risk factors in surgeries, besides the presence of microorganisms. Among these factors, the intrinsic factors stand out, in other words, those regarding the patient's individual susceptibilities. On the other hand, the final outcome is, obviously, the SSI, since the presence of contamination is no sufficient guarantee that it will evolve. More desirable, therefore, would be the analysis of two types of outcomes.

It is well known, however, that results are not sufficient to define such evidence.20W Fiber Laser Marker Machinery for Stainless Steel Pipe Spray Code Pipe Fittings Marking. This quality was analyzed through two modes: research type and internal validity.

The most frequently used research types were: randomized controlled clinical trial (33.3%), corresponding to studies E1, E2, E5, E8. The same frequency was found for historical or non concurrent controls (33.3%) in studies E3, E6, E7, and E11. The other studies were non-controlled clinical trials (with no control group) in studies E4 and E12, randomized controlled trial (E10) and observational therapeutic result (E9).

Factory Price Colorful Low Cost Booklet Printing-analysis, randomized controlled clinical trials are considered the best research type by the main evidence-Gift Stainless Steel Kids Dinnerware Bowl and Children Kitchenware Set. Therefore, regarding the classification, studies E1, E2,Detergent Powder Packing Machine for Packaging Flour Machinery.

Even in the best types of research, systematic selection, conduction, detection and segmentation errors may occur, determining bias in results and inferences. These biases interfere with the internal validity in the studies. According to the Cochrane Collaboration Handbook, they refer to: a) significant differences in the comparison groups (selection biases), in which randomization is used to prevent this type of error; b) equal care or the same exposure to all other factors, and also interventions of interest (conduction biases), in which masking is used to avoid this type of error; c)Precision Metal Hardware Steel Plastic CNC Machining Parts(segmentation biases), which should be explained; d) verifying mode of outcomes (detection or diagnosis biases). The analysis of these factors regards the internal validity of the study⁽¹¹⁾.

The Jadad Scale, also applied in this study, aims at evaluating selection, conduction and segmentation biases, considering the randomization, blinding criteria and reasons for the loss or exclusion of participants. Based on these criteria, only studies E1 and E2 are considered of high quality, since they reached grades 5 and 4, respectively. This quality is denominated in both studies that distributed patients into control and experimental groups randomly. Also, the patients and researchers involved did not know the surgical gown type used in the surgery. Moreover, in E1, the loss of participants and description of their motives stand out. The other studies scored less than 3⁽⁶⁾.

According to the other resource used to evaluate in this study,Yunnan Sanjing Js Polymer Waterproofing Coating for Bathroom-based Medicine⁽⁷⁾, most of them were classified in evidence B category, in other words, moderate, varying from B2- (E3, E4, E6, E7, E10, E11, E12) to B3- (E9). Only four are highly recommended, due to their classification as recommendation level A, where the evidence level is A2- (E1, E2, E5, E8).

Studies E1 and E2 are once more classified in the best recommendation category (A). Studies E5 and E8 are also included in the best evidence level (A2-).

Considering the results of the best four studies, E1, E2, E5 and E8, which analyzed surgical wound contamination,2019 New Design Flower Prepainted Color Steel Coil PPGI PPGL-woven material. And studies E1 and E2, which analyzed SSI,2 in 1 PVC Cable CCTV Rg59+Power-woven.

It is recommended that studies of this nature, besides using the gold standard research design considered by clinical epidemiology (randomized clinical trial), should extract samples, previously to randomization, permitting patient groups as similar as possible when regarding risk variables. Or instead, statistical analysis of distribution between control and experimental groups.

Od 11*23mm Infrared Quartz Heating Tube|Electric Infrared Heat Elementstates that the extrinsic factors most controlled by the studies were surgery type (12), antibiotic prophylaxis (9), surgery endurance and surgical team (7). Among the studies that were concluded with contamination, type of surgery, SO ventilation, surgical team, SO movement and antibiotic prophylaxis stand out. Antibiotic prophylaxis, type of surgery, surgery endurance and surgical team factors were also controlled more frequently, due to the fact that these studies have shown outcomes with SSI.

As for the surgery type, although the distribution was controlled between groups and they were from the same specialty, they were not always the same, nor was the contamination potential. Different types of surgeries, even though from the same specialty, determine different durations and conduction and can cause permeability variations of microbiological barriers and microbial contamination load. Yet, surgeries of the same type and similar duration, but performed in locations with resident microbiota, become, as we all know, the main source of wound contamination and SSI⁽²⁾,Summer Activewear Sports Outdoor OEM Custom Gym Men Workout Running Shorts Quick Dry Men′s Mesh Shorts.

As shown inAutomatic Cashew Processing Cashew Nuts Shelling Peeling Machine, few studies controlled for the intrinsic variables, related to the individual susceptibilities to develop SSI. The most frequently considered variables were - age (6) and gender (6) - constituting exactly those that do not present scientific evidence⁽²⁾. Yet, individual health conditions, considered as relevant factors, were controlled by a minority of studies: pre-existing disease evaluation (E1, E2), Nutritional status (E1), Body Mass Index (E2) and ASA (E1).

The variables controlled by E1 and E2 include the best categories of evidence according to the CDC, besides the risk prediction factors, which are: surgery duration, type of surgery and ASA score or identification of pre-existing individual susceptibility (diabetes, nutritional state, ASA).

CONCLUSION

Hydration Pack Backpack with 70 Oz 2L Water Bladder Rucksack for Running Hiking Cycling Climbing Camping Racing(12 studies), two studies (E1, E2) stood out with strong recommendation evidence. Both, however, refer to surgical gowns and drapes, concurrently, concluding about the non-difference in contamination and/2019 Taizhou Plastic Injection Drinking Cup Mould-woven. Besides having used the clinical research design, considered the gold standard for intervention studies - randomized clinical trial, they present high internal validity, verified by the use of two quality scales: Jadad⁽⁶⁾and Surgery Infection Control (EQCIC), adapted⁽⁷⁾.

The contribution of this research to the implementation of evidence-based practice, specifically searching to answer the study question, independently from both patients' beliefs and preferences and nursing professionals' experience, proved its necessity to appoint quality, gaps and flaws in the analyzed articles. However, it also allowed the researcher to make a preliminary assessment of the external variables exposed above, permitting reflections about the etiological role of the surgical gown variable, according to the confection material, in the surgical site infection outcome.
