Abstract:

Modern operating rooms are increasingly turning to contamination control by ventilating technology for the infectious control. The objective of this study is to present the strategic approach on performance improvement of the ventilating system for a hospital operating room under limit budget. A physical partition curtain has been proposed and conducted around the high efficiency particulate air (HEPA) filter of an operating room to validate the improvement of air distribution and contamination control. Numerical simulation of a full-scale operating room has been carried out at a district hosp

Abstract:

Forced ventilation is applied in clean rooms, specifically operating rooms, to ensure the health of both the patient and the medical staff. Ventilation reduces the risk of patient contamination, and its parameters are legally prescribed. In addition to preventing contamination, the ventilation system also ensures the creation of a comfortable environment for personnel who spend a large amount of working time in the operating room. This research focuses on the appropriate design of the air flow rate from the distribution element to the operating room. The PMV and PPD indexes were used to evalua

Abstract:

AbstractHealthcare associated infections in surgical procedures have long been the focus of scientific research. In Germany, more than 225,000 patients suffer from such infections each year [1]. However, the reduction of the microbiological contamination is not only limited by cleaning and disinfecting measures. The choice of the ventilation system in the operating room or the type of the clothing of the personnel during the operation is also an important factor contributing to patient safety and infection control. Currently there are different approaches for assessing the hygienic situation i

The COVID-19 pandemic has forced many countries to pose an emergency to contain the contamination and prevent the further spread of the infection. In this context, many societies and research papers were published to optimize guidelines and protocols for patients undergoing surgery and subsequent intubation. Accordingly, infection control is a critical approach to reduce the rate of contamination and risk of catching infections for suspected and confirmed COVID-19 patients. As a result, various guidelines were discussed in the current literature review, including guidelines to the patient, hea

Introduction: The operating room is a sterile and organized environment. Operating room contamination is one of the most life-threatening sources of nosocomial infections for patients, especially in transplant surgery, cardiac surgery, cystoscopy, and transurethral resection of prostate and bladder tumors. The air around the operating room environment can be contaminated or carry various microorganisms. Insufficiently sterilized operating rooms will likely increase operating room infections and lead to poorer prognostic outcomes for postoperative patients. This study aims to determine bacteria

Abstract:

One of the most important functions of air conditioning systems in operating rooms is to protect occupants against pathogenic agents transported by air. This protection is done by simultaneously controlling the air distribution, temperature, humidity, filtration and infiltration from other areas etc. Due to their low price, simple installation, operation and maintenance, window/wall air conditioning system have largely been used in operating rooms in Brazil, even if these types of equipment only recirculate the air inside the room without appropriate filtration and renovation with outdoor air.

Abstract:

Objective.To evaluate the performance of a new mobile air-treatment unit that uses nonthermal-plasma reactors for lowering the airborne bioburden in critical hospital environments and reducing the risk of nosocomial infection due to opportunistic airborne pathogens, such asAspergillus fumigatus.Methods.Tests were conducted in 2 different high-risk hospital areas: an operating room under simulated conditions and rooms hosting patients in a pediatric hematology ward. Operating room testing provided performance evaluations of removal rates for airborne contamination (ie, particles larger than 0.5

Abstract:

Background: The contaminated healthcare environment, including operating rooms (ORs), can serve as an important role in transmission of healthcare-associated pathogens. Studies are very limited regarding the level of contamination of ORs during the surgery of a patient on contact precautions and the risk to the next surgery patient after standard room cleaning and disinfection. Objective: Here, we investigated the microbial burden on the OR environment when patients on contact precautions receive surgery, and we assessed the impact of cleaning and disinfection on the contamination of OR enviro

Abstract:

Inadequate staff behaviors in an operating room (OR) may lead to environmental contamination and increase the risk of surgical site infection. In order to assess this statement objectively, we have developed an approach to analyze OR staff behaviors using a motion tracking system. The present article introduces a solution for the assessment of individual displacements in the OR by: (1) detecting human presence and quantifying movements using a motion capture (MOCAP) system and (2) observing doors’ movements by means of a wireless network of inertial sensors fixed on the doors and synchronized

AbstractObjective: To study the effect of a portable HEPA-filtered air exhaust system (Stackhouse Freedom Surgical Helmet System) on airborne microbial contamination in a modern conventional operating room.Design and Setting: Microbial air sampling was done with a two-stage Anderson sampler at the wound site during 46 total joint replacements. All operations were performed by the same surgeon in the same operating room at a large community hospital.Results: In 18 cases done without air exhaust hoods, the number of bacterial and fungal colony-forming units (CFU) ranged from 0.6 to 11.7 (mean, 3

Abstract:

Mycobacterium chimaera infections have mainly been associated with the heater-cooler unit (HCU) and, ultimately, linked to contaminated aerosols in the operation room. The contamination status of HCUs seems to be influenced by the maintenance, therefore, according to the manufacturer’s recommendations, peracetic acid (Puristeril) was introduced to increase HCU cleaning and disinfection protocol maintenance. Aerosol dispersion from Puristeril during maintenance can cause adverse effects to nearby workers. We aim to describe our technique to reduce the impact of Puristeril on operating room staf

Abstract:

Indoor air quality in hospital operating rooms is of great concern for the prevention of surgical site infections (SSI). A wide range of relevant medical and engineering literature has shown that the reduction in air contamination can be achieved by introducing a more efficient set of controls of HVAC systems and exploiting alarms and monitoring systems that allow having a clear report of the internal air status level. In this paper, an operating room air quality monitoring system based on a fuzzy decision support system has been proposed in order to help hospital staff responsible to guarante
