INTRODUCTION: Modifications of the temporomandibular joint position after mandible osteotomy are reluctantly accepted in orthognathic surgery. To tackle this problem, we developed a new navigation system using miniaturized electromagnetic sensors. Our imageless navigation approach is therefore optimized to avoid complications of previously proposed optical approaches such as the interference with established surgical procedures and the line of sight problem. MATERIAL AND METHODS: High oblique sagittal split osteotomies were performed on 6 plastic skull mandibles in a laboratory under conditions comparable to the operating theatre...

AIMS: To develop financial models which offset additional costs associated with femtosecond laser (FL)-assisted cataract surgery (FLACS) against improvements in productivity and to determine important factors relating to its implementation into the National Health Service (NHS). METHODS: FL platforms are expensive, in initial purchase and running costs. The additional costs associated with FL technology might be offset by an increase in surgical efficiency. Using a 'hub and spoke' model to provide high-volume cataract surgery, we designed a financial model, comparing FLACS against conventional phacoemulsification surgery (CPS)...

There is a real risk of electrical accidents in the operating theatre, with the growing number of electrical, electronic and flammable liquids used. Electrocautery remains the most commonly used device for its electrosurgical effect of coagulation or tissue section. When it is defective or misplaced on a small area of the skin, it can cause a typically deep, slow healing skin burn. It adds an unexpected iatrogenic morbidity to the initial condition, with devastating consequences for the patient, the surgeon and sometimes the hospital...

BACKGROUND: Subcutaneous emphysema is defined as presence of air or gas in subcutaneous tissue layer. It may be localized or generalized due to various aetiological factors. Although SE and pneumomediastinum are self-limiting conditions, life-threatening complications may develop. Escape of air into both pleural cavity causing bilateral pneumothorax and tension pneumothorax can be termed as malignant emphysema. PURPOSE: To report a case of malignant generalized subcutaneous emphysema in early postoperative phase following palatoplasty...

The development of low profile gamma-ray detectors has encouraged the production of small field of view (SFOV) hand-held imaging devices for use at the patient bedside and in operating theatres. Early development of these SFOV cameras was focussed on a single modality-gamma ray imaging. Recently, a hybrid system-gamma plus optical imaging-has been developed. This combination of optical and gamma cameras enables high spatial resolution multi-modal imaging, giving a superimposed scintigraphic and optical image...

BACKGROUND: Cancellations of planned elective surgical operations increase financial cost to the patient and the hospital. OBJECTIVES: To determine the rate and reasons for cancellations, estimate the cost incurred by such cancellations and recommend possible solutions. METHODS: We did a prospective descriptive study of cancellations of elective general surgical operations over the 1-year period January - December 2014 in the main theatre at Pietersburg (PTB) Hospital, Limpopo Province, South Africa...

OBJECTIVES: To assess the outcomes of performing percutaneous nephrolithotomy (PCNL) in a modified supine position, more feasible for surgeons, anaesthetists, and operating theatre staff, as well as for the patient himself, and evaluating it in comparison to the standard prone position. PATIENT AND METHODS: A retrospective, case-control study was conducted between January 2011 and December 2015. In all, 197 patient's records were reviewed. The initial 101 patients were operated upon in prone position...

A woman aged 67 years attended the emergency department with acute abdominal and back pain of 1-day duration with associated vomiting. The patient had multiorgan failure. Resuscitation was started with intravenous fluids and vasopressors. An abdominal CT scan was completed which confirmed the diagnosis of acute gastric volvulus. The patient was successfully resuscitated from a cardiorespiratory arrest during transfer to the operating theatre. The patient subsequently underwent a total gastrectomy with stapling of the oesophageal and duodenal stumps...

It was when a patient with a type A aortic dissection refused surgical treatment that our eyes were opened to the importance of shared decision-making (SDM). As these patients are usually transferred to the operating theatre without any opportunity for discussion about the indication for surgery, our department of cardiothoracic surgery rapidly became keen on applying the principles of SDM to all our patient contacts - as did other departments in our hospital. However, when I became a patient myself and was invited by my physicians to take part in the decision-making process about my treatment, I was surprised to find that I felt very reluctant to do so and preferred to be not involved at all...

OBJECTIVE/BACKGROUND: Post-endarterectomy hypertension (PEH) is a well recognised, but poorly understood, phenomenon after carotid endarterectomy (CEA) that is associated with post-operative intracranial haemorrhage, hyperperfusion syndrome, and cardiac complications. The aim of the current study was to identify pre-operative clinical, imaging, and physiological parameters associated with PEH. METHODS: In total, 106 CEA patients undergoing CEA under general anaesthesia underwent pre-operative evaluation of 24 hour ambulatory arterial blood pressure (BP), baroreceptor sensitivity, cerebral autoregulation, and transcranial Doppler measurement of cerebral blood flow velocity (CBFv) and pulsatility index...

INTRODUCTION: Robotic-assisted laparoscopic hysterectomy (RALH) has become a widely used approach for women with endometrial cancer and has replaced laparotomy. It has been questioned if the increased costs are justified by superior surgical outcomes. The aim of the present study was to examine the frequency, types and severity of post-operative complications after total abdominal hysterectomy (TAH) and RALH using the Clavien-Dindo classification of surgical outcomes. METHODS: A non-randomised, controlled before and after study of 360 women was conducted; 202 underwent RALH and 158 TAH (historical controls)...

BACKGROUND: Centenarians are the fastest rising age group in Ireland. Hip fractures most commonly affect older adults and are associated with significant morbidity and mortality, as well as the financial cost of healthcare resources. Despite this, very little is known regarding hip fractures in centenarians. The aim of this study was to investigate our experience with hip fractures in this group and to record the cost of treating these fractures to identify both the social and economic impact these injuries impose on the health system...

BACKGROUND: Total laparoscopic hysterectomy (TLH) is established as a safe method of hysterectomy, with a satisfactory patient experience. However, most published data derive from high-volume centres with experienced teams. It is not clear whether these data translate to smaller centres? AIMS: To evaluate the implementation of a minimally invasive option for hysterectomy at a regional public hospital in New Zealand. MATERIALS AND METHODS: Prospective audit of 120 cases of TLH over three years...

PURPOSE: The purpose of this study is to record the 30-day and inpatient morbidity and mortality in paediatric patients in a tertiary neuroscience centre over a 2-year period. The intentions were to establish the frequency of significant adverse events, review the current published rates of morbidity in paediatric neurosurgical patients and propose three clinical indicators for future comparison.

BACKGROUND: Extended control of staff exposure in interventional radiology has been legally required over the last few years. This is determined by a number of factors, including the type of procedure, technical conditions and methodology. In orthopedic procedures fluoroscopy is used to control surgical reconstructions. An influence of particular factors on the registered values of doses received by the members of medical team performing osteosynthesis for limb fractures is presented in this paper...

The NHS Institute for Innovation and Improvement has determined that a £7 million saving can be achieved per trust by improving theatre efficiency. The aim of this quality improvement project was to improve orthopaedic theatre turnaround without compromising the patient safety. We process mapped all the stages from application of dressing to knife to skin on the next patient in order to identify potential areas for improvement. Several suggestions arose which were tested in multiple PDSA cycles in a single theatre...
