Zaffer A Qasim, Robert A Sikorski
Resuscitative endovascular balloon occlusion of the aorta is a new procedure for adjunctive management of critically injured patients with noncompressible torso or pelvic hemorrhage who are in refractory hemorrhagic shock, ie, bleeding to death. The anesthesiologist plays a critical role in management of these patients, from initial evaluation in the trauma bay to definitive care in the operating room and the critical care unit. A comprehensive understanding of the effects of resuscitative endovascular balloon occlusion of the aorta is essential to making it an effective component of hemostatic resuscitation...

Our objectives in reviewing the initial experience of a hereditary hemorrhagic telangiectasia center of excellence (HHT COE) were to better understand the interventions being performed in the comprehensive care of these patients and to present the early data as a reference for other tertiary centers considering starting an HHT COE. We conducted a retrospective review of consecutive patients referred to our newly developed HHT COE for evaluation and treatment between May 2010 and June 2013. Clinical presentation, otolaryngologic treatments, and other operative interventions were analyzed...

We conducted a retrospective case review to determine if the presence of an Accreditation Council for Graduate Medical Education (ACGME) fellowship-trained pediatric anesthesiologist improves efficiency during pediatric tonsillectomies and adenotonsillectomies in hospitals that do not have dedicated pediatric operating rooms and, if so, to determine which specific anesthesia practices might account for such a difference. We reviewed the charts of all patients aged 12 years and younger who had undergone a tonsillectomy or adenotonsillectomy from Jan...

BACKGROUND: Non-technical skills (NTS) are being increasingly recognised as vital for safe surgical practice. Numerous NTS rating systems have been developed to support effective training and assessment. Yet despite the additional challenges posed by robotic surgery, no NTS rating systems have been developed for this unique surgical environment. This study reports the development and validation of the first NTS behavioural rating system for robotic surgery. METHODS: A comprehensive index of all relevant NTS behaviours in robotic surgery was developed through observation of robotic theatre and interviews with robotic surgeons...

BACKGROUND AND PURPOSE: The reliability of post-implant dosimetry in the OR depends on the geometrical variability of implant and anatomy after the procedure. The purpose was to gain detailed information on seed displacement patterns in different sectors of the prostate. MATERIALS AND METHODS: Of 33 patients with stranded seed implants the seed geometry and the dose distribution were compared between the situation in the OR just after the procedure, based on ultrasound images, and the situation after 1month, based on registered CT and MR images...

C-N-S-tri doped TiO2 anatase phase was synthesized using a facile, effective and novel sonochemical method at low frequency (20kHz) and at room temperature. Titanium butoxide as the titanium precursor and thiourea as the dopant source were used in the synthesis of the photo-catalyst. The effects of important parameters such as thiourea/Ti molar ratio, ultrasound intensity, sonication time and temperature were studied on the synthesis of tri-doped TiO2. The XPS results confirmed the presence of N, S, and C in the photo-catalyst...

Irreducible ankle fractures are a relatively rare phenomenon. We present a case of a pronation abduction-type ankle fracture that was irreducible in the emergency room despite sedation. The patient was taken to the operating room, where the posterior tibialis tendon and retinaculum, deltoid ligament, and anteromedial capsule were found to be trapped within the joint. After removal of the tissue, alignment was restored. The patient did well clinically and was advanced to full weightbearing at 6 weeks. This is, to the best of our knowledge, the first report of entrapment of all 4 anatomic structures, preventing closed reduction...

Soils contaminated with mercury (Hg) have proved expensive and logistically difficult to remediate. Research continues into finding suitable environmentally-friendly and efficient ways of achieving this end. Bioremediation is an option, which employs the strategies microorganisms have evolved to deal with Hg. One microbial strategy involves uptake and intracellular volatilisation of mercuric ions, which passively diffuse from the cell and back into the atmosphere. In this work, Pseudomonas veronii cells grown to stationary phase were immobilised in a xanthan gum-based biopolymer via encapsulation...

INTRODUCTION: While several patient and operative variables have been shown to be associated with an increased risk of postoperative wound events, the association between surgical hat type worn by surgeons and postoperative wound events remains controversial. The purpose of this study is to investigate the association between type of surgical hat worn by surgeons and the incidence of postoperative wound events following ventral hernia repair using the Americas Hernia Society Quality Collaborative database...

An open challenge for single-molecule electronics is to find stable contacts at room temperature with a well-defined conductance. Common coinage metal electrodes pose fabrication and operational problems due to the high mobility of the surface atoms. We demonstrate how molecules covalently grafted onto mechanically robust graphite/graphene substrates overcome these limitations. To this aim, we explore the effect of the anchoring group chemistry on the charge transport properties of graphite-molecule contacts by means of the scanning tunneling microscopy break-junction technique and ab initio simulations...

Intrinsic signal optical imaging (ISOI) within the first decade of its use in humans showed its capacity as a precise functional mapping tool. It is a powerful tool that can be used intraoperatively to help a surgeon to directly identify functional areas of the cerebral cortex. Its use is limited to the intraoperative setting as it requires a craniotomy and durotomy for direct visualization of the brain. It has been applied in humans to study language, somatosensory and visual cortices, cortical hemodynamics, epileptiform activity, and lesion delineation...

BACKGROUND AND OBJECTIVES: Optical imaging to guide cancer resections is rapidly transitioning into the operating room. However, the sensitivity of this technique to detect subclinical disease is yet characterized. The purpose of this study was to determine the minimum range of cancer cells that can be detected by antibody-based fluorescence imaging. METHODS: 2LMP (breast), COLO-205 (colon), MiaPaca-2 (pancreas), and SCC-1 (head and neck) cells incubated in vitro with cetuximab-IRDye800CW (dose range 8...

OBJECTIVES: There is no standardized approach to assess and manage perioperative neurologic deficit (PND) in patients undergoing spinal surgery. This survey aimed to evaluate the awareness and usage of clinical practice guidelines (CPGs) as well as investigate how surgeons performing spine surgeries feel about and manage PND, and how they perceive the value of developing CPGs for the management of PND. METHODS: An invitation to participate was sent to the AOSpine International community...

OBJECTIVE: The summer surgery program (SSP) was founded in 2012 as an educational program for students at the critical juncture between high school and college to engender interest in medicine, science, and innovation. This program has a distinct emphasis on innovation and problem solving based on real-life operative challenges identified by students during surgical observation in the operating room. The effect of the SSP regarding postsecondary education and career goals was evaluated by participants using a follow-up questionnaire...

STUDY OBJECTIVE: Medical residents working overnight call shifts experience sleep deprivation and circadian clock disruption. This leads to deficits in sensorimotor function and increases in workplace accidents. Using quick tablet-based tasks, we investigate whether measureable executive function differences exist following a single overnight call versus routine shift, and whether factors like stress, rest and caffeine affect these measures. DESIGN: A prospective, observational, longitudinal, comparison study was conducted...
