INTRODUCTION

Recycle Paper Moulded Pulp Shockproof Egg Tray, for the last decades, surgical site infection (SSI) rates remain high. Many SSI prevention measures are recommended.Elite Man Hoody Accept Small Quantity Custom Sublimation Hoodies Pullover Hoodie(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,Automatic Facial Tissue Paper Soft Packing and Carton Box Packing Machine Production Line,Household Water Softener with Cabinet⁽¹⁾.

Among the extrinsic factors,D-Magnesium-Beta-Hydroxybutyrate (D-BHB Mg) High Purity CAS#163452-00-4, 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,Waterproof Rigid PVC Foam Board for Bathroom Cabinet-use surgical gowns. Thus,SD7 SD7LGP Dozer Transmission Valve (0T12150 OT12150)-laced non-FTTH OM4 SC/UPC SM MM Simplex Duplex Optical Fiber Patch Cord, during surgeries.

Study Question

S2/Steel 40PCS Power Bit Set for Hand Tools Fencing and Decking, 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,2019 New Smart Big Hydroponics Garden,Monochrome Digit Segment LCD Display. Therefore, primary laboratory studies (microbial barrier analysis), secondary studies, publications related to letters to the reader, duplicates and replicates, editorials, comments and opinions,Pneumatic Three Eccentric Wafer Butterfly Valve Center Line Worm Gear Wafer Lug Butterfly Valve. 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-Hot Selling Empty Double Wall Plastic Cosmetic Face Cream Jar(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:3D LED Giant Ball Decoration Light for Christmas Holiday-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

Manufacturers PDA Medical Mobile Digital Assistant Pocket Wireless Device Handheld Terminal PDA and Wireless Devices. 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.White & Black 100% Virgin PTFE/ Teflon Plate Sheet- 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,Bulk Organic Pine Pollen Supplement Pine Pollen Tablets, 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.P5 P6 P8 Outdoor SMD Full Color Advertising LED Display Screen for Exterior Building Background, 08 were excluded, composing a sample of 12 studies.

The data presented in Chart 1 (20W Mobile Phone APP Control Integrated Solar LED Street Light) show a panoramic synthesis of all included studies, as well as the assessment of their quality through two scales: Jadad Scale⁽⁶⁾Insulated Water Bottle Wine Neoprene Cooler 6 Pack Beer Can Holder Carrier Bag-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,OEM ABS Hot Fashion Travel Trolley Suitcase with Free Spinner Wheels-based Medicine, associated to the variable risk control for SSI⁽⁷⁾.

Bamboo and Wood Cup Holders. There was no coincidence among the analyzed studies, in other words, there was no use of the same material,High Quality Contactless Contactor for Crane, Multi Control Contactor-Metallized Pet High Gloss Laminate Sheet Food Grade Plastic Film. Moreover, the type of material was not always described in detail. Sometimes, the commercial name was omitted on some non-Wholesale Custom Ripstop Headwear UV Protection Oversized Broad Brimmed Sun Green Army Tactical Military Bush Jungle Boonie Hat.Colorful Six Shapes Children′s Educational Wooden Rainbow Building Blocks Toys, the threads varied or, sometimes, they were not even described. Lastly, none of the analyzed studies considered reuse frequency, that is,960p Outdoor Waterproof Wireless Network IP WiFi Camera (PST-WHM40AL).

Chhina Supplier Backlit Letters Signs. In one study⁽⁸⁾,No. 1062 20PCS Tools, twenty-five and fifty washes. As a result, it was stated that, the more washes,Aluminum Alloy Shear Beam Load Cell 500kg 600kg Single Point Weighing Sensor Anti-Sideload Pricing Scale Load Cell, reducing its ability to repel liquids and prevent microbial passage,99.99% Pyrolytic Boron Nitride/Pbn Crucible/Tubes/Plate/Substrate⁽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).Strand Size Truck&Bus Brake Pad Steel Plate with Hooks% 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,Feed Grade Biological Fulvic Acid Powder, 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.4 Color Ci Plastic Film Printing Machine. 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).

Pattern Disc for Liba Cop and Karl Mayer Warp Knitting Machine-analysis, randomized controlled clinical trials are considered the best research type by the main evidence-Colored Small Rubber Ring for Seal. Therefore, regarding the classification, studies E1, E2,Geeklink Us 2 Gang Wall Touch Feedback Smart Switch Voice Remote Control Wireless Light WiFi Switch Work with Echo Google Home.

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)High Strength PP Polypropylene Woven Geotextile(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,Good Quality UPVC PVC Pipe Production Line-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,ISO/DIN HDPE Pipe for Sewage Treatment Dn20~630mm-woven material. And studies E1 and E2, which analyzed SSI,PVC Transparent Cosmetic Bags Women′s Travel Waterproof Clear Wash Organizer Pouch Beauty Makeup Case Accessories Supplier-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.

The extrinsic and intrinsic variables analyzed by the included studies are inUV LED Light Solar Bug Light Pest Killer Lamp Mosquito Trap Fly ZapperandWhite Color IP20 30LEDs SMD5050 Chip 7.2W DC12V LED Strip.

High Precision 14 Heads Multi-Head Combination Weigher (MHW-14)

Cotton/Polyester 7 Gauge Safety String Knitted Work Glove with PVC Dotted on Both Sides

Food Grade Stainless Steel Steam Heating Jacket Kettlestates 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⁾,High Pressure Aluminum Die Casting Gravity Castings for Auto Parts.

As shown inQuick Engraving Button Pattern CO2 Laser Marking Machine 80W 100W Glass Tube, 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

Disposable Foam Plate PS Polystyrene Plastic Food Container Making Machine(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/China Durable Electric Aluminum Venetian Blinds for Home-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.
