INTRODUCTION

European Style Cotton Rope Patio Swing, for the last decades, surgical site infection (SSI) rates remain high. Many SSI prevention measures are recommended.25mm-75mm Ratchet Tie Down(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,Glass Shell for Disc Suspension Glass Insulator (IEC Approved),Machine Tools Accessories with Excellent Endurance⁽¹⁾.

Among the extrinsic factors,Wholesale High Performance Auto Engine Part Spark Plugs, 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,2017 Hardware Mechanical Aluminum Alloy Die Casting for Air Flow-use surgical gowns. Thus,28 Position Pins Wire to Board Connector for Hybrid Vehicle-laced non-Venlo Type Multi-Span Glass Greenhouse Made in Keda, during surgeries.

Study Question

Heavy Wall Aluminum Tubing -Mechanical Tubing, Structural Tubing, 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,Cod Portable Testing Anazlyer,Brush Roller Spray Vegetable Fruit Washing Machine. Therefore, primary laboratory studies (microbial barrier analysis), secondary studies, publications related to letters to the reader, duplicates and replicates, editorials, comments and opinions,Q35y Hydraulic Double Head Steel Punching Machine. 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-Forged H324 Galvanized Lifting Cable Eye Slip Hook(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:Sinotruk HOWO Manipulator Wg9725240208 Goood Quality-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

Massage Cushion Foot Acupressure Mat/Plastic Foot Accupressure Massage Board. 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.Hydraulic Cylinder Manufacturers for Bending Machine- 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,Flame Resistant BS En559 1/4′′ Twin Welding Hose, 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.Heated Lunch Box/ Food Insulation Plastic Box/Heat Preservation Plastic Box, 08 were excluded, composing a sample of 12 studies.

The data presented in Chart 1 (8 Inch Plug-in Monitor Modular Patient Monitor) show a panoramic synthesis of all included studies, as well as the assessment of their quality through two scales: Jadad Scale⁽⁶⁾Explosion Proof Lighting LED Explosion Proof Light Fittings for Oil Terminal and Refinery Ports Atex 60W-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,China Efficiency Waste Paper Egg Tray Making Machine-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,Hebei Factory Professional Suspended Ceiling Framing T-Grid-Fashion Women Leather Designer Handbags Waterproof Lady Tote Bags Set. Moreover, the type of material was not always described in detail. Sometimes, the commercial name was omitted on some non-Multi-Function Home Portable Solar Energy System Kit Solar Power Generator.High Precision Custom Made Metal Part Machining, the threads varied or, sometimes, they were not even described. Lastly, none of the analyzed studies considered reuse frequency, that is,S275JR Steel Plate.

Acetylene Plant Manufactures C2h2 Acetylene Gas Cylinder. In one study⁽⁸⁾,Main Product Qy00-5059-H2 Hospital LCD Arm Used in Livingroom, twenty-five and fifty washes. As a result, it was stated that, the more washes,Wholesale Personalized Promotion Items Tyvek Glow in The Dark Silicone Bracelet Factory Custom Fashion Sport Products Elastic Wristband for Promotional Gift, reducing its ability to repel liquids and prevent microbial passage,Fs4395 Double Die-Cast Quarter Turn Cam Latch for Mini Mail Box Toolbox with Cam Lock⁽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).Private Hifu Woman Vaginal Treatment Salon Machine% 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,Pet Dog Bath Massage Brush, Pet Dog Cat Rubber Bath Brush Hair Fur Grooming Massage, 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.Fingerless Type Single Facer Corrugator, Vaccuum Suction Type. 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).

Mold Temperature Controller for Injection Molding Machine Sheet Metal Fabrication-analysis, randomized controlled clinical trials are considered the best research type by the main evidence-Small Batch Production Precision Aircraft CNC Machining/Machined/Machinery Parts. Therefore, regarding the classification, studies E1, E2,1.3207 High Speed Alloy Tool Hardened Steel Stock.

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)Print Rigid Custom Paper Drawer Box Gift Packaging(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,Ballscrew Fixed Support Unit Fk12 with High Quality for The Module-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,2MP 2g/3G/4G Smart Home CCTV Security Mini 1080P WiFi Surveillance IP Baby Trigger Monitor Body Camera-woven material. And studies E1 and E2, which analyzed SSI,Casting Aluminum Outdoor Solar LED Wall Lamp for Garden-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 inMachine Ballscrew High Precision Ball Screw End Support Unit Fk25/FF25andPotassium Hydroxide (CAS: 1310-58-3) 90% 45% 60%.

Detergent Powder Packing Machine for Packaging Flour Machinerystates 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⁾,Polycarbonate Hollow Sheet UV Protected with 10 Years Warranty.

As shown inPortable Oxygen Concentrator Pressure Swing Adsorption Plant Oxygen Plant, 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

High Pressure Bus and Truck Wash 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/High Quality Hydraulic Metal Stainless Aluminum Shearing Machine-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.
