BACKGROUND: Surgical site infection (SSI) rates vary from 1% to 5% in the month following surgery. Due to the large number of surgical procedures conducted annually, the costs of these SSIs can be considerable in financial and social terms. Many interventions are used with the aim of reducing the risk of SSI in people undergoing surgery. These interventions can be broadly delivered at three stages: preoperatively, intraoperatively and postoperatively. The intraoperative interventions are largely focused on decontamination of skin using soap and antiseptics; the use of barriers to prevent movement of micro-organisms into incisions; and optimising the patient's own bodily functions to promote best recovery...

Volatile anaesthetic agents are a potential occupational health hazard to theatre and recovery staff. Operating theatres and anaesthetic rooms are required to be equipped with scavenging systems, but recovery units often are not. We compared exhaled, spectrophotometric sevoflurane and desflurane concentrations 15 cm from the mouth ('patient breathing zone') and 91 cm laterally to the patient ('nurse work zone') in 120 patients after tracheal extubation who were consecutively allocated to either ISO-Gard mask oxygen/scavenging or standard oxygen mask, 0 min, 10 min and 20 min after arrival in the theatre recovery unit...

OBJECTIVE: Mortality rates from birth asphyxia in low-income countries remain high. Face mask ventilation (FMV) performed by midwives is the usual method of resuscitating neonates in such settings but may not always be effective. The i-gel is a cuffless laryngeal mask airway (LMA) that could enhance neonatal resuscitation performance. We aimed to compare LMA and face mask (FM) during neonatal resuscitation in a low-resource setting. SETTING: Mulago National Referral Hospital, Kampala, Uganda...

Air cleanliness in operating theatres (OTs) is an important factor for preserving the health of both the patient and the medical staff. Particle contamination in OTs depends mainly on the surgery process, ventilation principle, personnel clothing systems and working routines. In many open surgical operations, electrosurgical tools (ESTs) are used for tissue cauterization. ESTs generate a significant airborne contamination, as surgical smoke. Surgical smoke is a work environment quality problem. Ordinary surgical masks and OT ventilation systems are inadequate to control this problem...

STUDY OBJECTIVE: The study objective is to determine whether extraglottic airway devices (EADs) with or without mask aperture bars (MABs) result in similar anatomical positions in patients undergoing surgery. DESIGN: Prospective, randomized, crossover comparison of four extraglottic airway devices. SETTING: Operating theatre at a large teaching hospital. PATIENTS: Eighty consenting patients scheduled to undergo surgery with general anesthesia...

The optimal end-tidal sevoflurane concentration for successful ProSealTM (Teleflex, Morrisville, NC, USA) laryngeal mask airway (PLMA) versus ClassicTM (Teleflex, Morrisville, NC, USA) laryngeal mask airway (CLMA) insertion in unpremedicated anaesthetised adults is unknown. We determined end-tidal sevoflurane concentrations for successful insertion in fifty percent of anaesthetised adults. This randomised, prospective, double-blind study was conducted in the operating theatre of a government tertiary care hospital...

BACKGROUND: Since their emergence from the operating theatre over a decade ago, supra-glottic airways (SGA) have become increasingly common in the management of out-of-hospital cardiac arrest (OOHCA) with laryngeal masks (LM) the most common SGA. The proliferation of LMs in the prehospital setting has occurred despite lower than expected rates of successful insertion being reported. METHODS: We conducted a single-centre, prospective parallel-group, 'open label' randomised controlled trial in subjects with OOHCA (aged greater than or equal to 12 years of age; weighing greater than or equal to 30 kg) were allocated to either the i-gel supraglottic airway (IG-SGA) or the Portex Soft Seal Laryngeal Mask (PSS-LM) within a large Australian ambulance service...

BACKGROUND: The optimal end-tidal sevoflurane and desflurane concentration for successful ProSeal laryngeal mask airway (PLMA) removal in unpremedicated anaesthetised adults has not been determined. OBJECTIVES: We determined end-tidal sevoflurane and desflurane concentration in 50% of anaesthetised adults (EC50: concentration at which there is 50% chance of patients showing 'no movement' response) for smooth PLMA removal. DESIGN: Randomised controlled double blind study...

BACKGROUND: Sterile water injections have been used as an effective intervention for the management of back pain during labour. The objective of the current research is to determine if sterile water injections, as an intervention for back pain in labour, will reduce the intrapartum caesarean section rate. METHODS/DESIGN: HASH(0x4f6e408) DESIGN: A double blind randomised placebo controlled trialSetting: Maternity hospitals in AustraliaParticipants: 1866 women in labour, ≥18 years of age who have a singleton pregnancy with a fetus in a cephalic presentation at term (between 37 + 0 and 41 + 6 weeks gestation), who assess their back pain as equal to or greater than seven on a visual analogue scale when requesting analgesia and able to provide informed consent...

Extraglottic airway devices (EGA) are not only used in routine anaesthesia practice, they also have a distinct value for in-hospital and out-of-hospital difficult airway management. In the environment of the intensive care unit (ICU) EGA are not used on a regular basis. However, expertise and knowledge regarding EGA coming from the operating theatre or the out-of-hospital setting may also be of value for the ICU setting. This review presents the potential indications for EGA on the ICU for the management of difficult airway situations as well as during percutaneous tracheotomy...

Diathermy is used in most theatres for every case but how many people think about the contents of diathermy plume or surgical smoke? Surgical smoke is an unpleasant smell that leaves many considering whether surgical masks reduce the risk of inhaling its contents. This article suggests that practitioners should be more aware of its contents and take action to lessen the risk to themselves and their colleagues.

Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus...

BACKGROUND: Observing surgical procedures is a beneficial educational experience for medical students during their surgical placements. Anecdotal evidence suggests that operating theatre related syncope may have detrimental effects on students' views of this. Our study examines the frequency and causes of such syncope, together with effects on career intentions, and practical steps to avoid its occurrence. METHODS: All penultimate and final year students at a large UK medical school were surveyed using the University IT system supplemented by personal approach...

Three-dimensional capture of the surface of soft tissue is a desirable support for documentation and therapy planning in plastic and reconstructive surgery concerning the complex anatomy of the face, particularly cleft lip and palate (CLP). Different scanning systems are used for capturing facial surfaces. These systems are mostly based on a static linear measuring arrangement. Established systems work on the basis of coded white light or linear laser triangulation and digital stereophotogrammetric approaches...

OBJECTIVES: To measure the extent of dilution of helium-oxygen (heliox) by room air when given via high concentration reservoir mask to spontaneously breathing subjects. Substantial dilution of heliox by room air under these circumstances might alter its physical properties sufficiently to negate any potential clinical benefit in obstructive respiratory failure. DESIGN: Healthy volunteers breathing different concentrations of helium in oxygen via two different masks in a randomised crossover design...

AIM OF THE STUDY: While several techniques are used for the management of difficult intubation (DI) in planned conditions in the operating theatre, they are not always suitable or usable in pre-hospital emergencies. We decided to assess the intubating laryngeal mask airway (ILMA) after failure of tracheal intubation (TI) under direct laryngoscopy. MATERIAL AND METHODS: After emergency physicians of the mobile intensive care unit were trained (theory and training on manikin) in using the ILMA (Fastrach), prospective data were collected after each use from March 2002 to December 2005...
