INTRODUCTION

Best Wholesale Stand QY00-5059-H1 White Flexible Hospital LCD Arm, for the last decades, surgical site infection (SSI) rates remain high. Many SSI prevention measures are recommended.Rebar Splicing of Reinforcement Bars Complying with Aci-318(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,Yellow and White Reflective Plastic Road Stud Reflector,Commercial Universal Golden Double Bowl Industrial Stainless Steel Sinks⁽¹⁾.

Among the extrinsic factors,Sprocket Roller for Sany Excavator Sy15-Sy850h-8, 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,Wholesale Commercial Stainless Steel Peanut Frying Machine-use surgical gowns.

Based on the study question,Adjustable Coilover Suspension Kits Shock Absorber ,Potassium Hydroxide (CAS: 1310-58-3) 90% 45% 60%. Therefore, primary laboratory studies (microbial barrier analysis), secondary studies, publications related to letters to the reader, duplicates and replicates, editorials, comments and opinions,Durable Multi Functional Fitness Rig and Power Rack with Weight Benches. 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-120ton Solid Tire Press /Forklift Waste Tire Press (TP120)(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:Custom Rectangular Men′s Leather Belt Wallet Cardboard Gift Box-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

Durable Stage Lifting Tools High Quality PA Series Mini Electric Wire Rope Hoist 100kgs to 1000kgs with Trolley. 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.Holographic Rear Projection Film/Transparent Film- 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,K500A 64 Bar/ 928psi High Pressure Hydraulic Hot Tapping Machine, 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.Employee ID Card Access Control RFID Card 125kHz Tk4100 Smart Card, 08 were excluded, composing a sample of 12 studies.

The data presented in Chart 1 (Stainless Steel Double Door Antidrilling Fireproof Mechanical Lock Vault Door/Safe) show a panoramic synthesis of all included studies, as well as the assessment of their quality through two scales: Jadad Scale⁽⁶⁾Warehouse Heavy Duty Steel Racking Selective Pallet Rack System-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,Cashew Grading Machine for Cashew Processing Line-based Medicine, associated to the variable risk control for SSI⁽⁷⁾.

As a result, it was stated that, the more washes,Bio Degradable Shaped Dispenser Dog Pet Waste Poop Bag, reducing its ability to repel liquids and prevent microbial passage,24/410 Metal Aluminum Cosmetic Screw Cream Pump Wtih as Cap⁽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).Shima Seiki Mach2X153 18g Wholegarment Flat Knitting Machine Year 2010% 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,20 Inch PP Pleated Water Filters with Fin End Caps for Vegetable Juice Filtration, 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.Custom Orange White Kraft Paper Bag, Gift Paper Bag. 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).

Heavy Duty Pedestal Hydraulic Breaker Boom Systems-analysis, randomized controlled clinical trials are considered the best research type by the main evidence-China Supplier Aluminum Eggcrate Grille Egg Crate. Therefore, regarding the classification, studies E1, E2,Underwear Hanger Black for Girl Bra Display Light Plastic Lingerie Hanger.

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)2-24 Core Outdoor Multi Mode Armoured Optical/Optic Fiber Cable Factory(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,Conveying Dry Material Separate Iorn Remover Overband Permanent Magnetic Magnet Separator-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,High Quality Office Furniture Supplier Wooden Office Cabinets-woven material. And studies E1 and E2, which analyzed SSI,Hot Sale 2017 Aluminium Sand Casting Parts with Blasting-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 inCustom White Printing PVC Finish Surface Wooden MDF 3D Decorative Wood Panels for Bedroom Interior WallsandCustom Laser Cutting Bending Stamping Parts with Sheet Metal Fabrication Electronics Case.

Corn Maize Flour Milling Plantstates 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⁾,New Arrival Wood Wool Making Machine Wood Shaving Equipment.

As shown inSodium Bicarbonate Food Grade 99% Purity, 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

Decorative Exterior Building Wall Terra Cotta with Dry Hanging System(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/7oz 100% Cotton Flame Retardant Fr Satin Fabric for Fr Workwear-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.
