Abstract
From the mid-18th century, several different stimulations were used to attempt to resuscitate apparently dead people. These include sound, smell, and light stimulation to the ear, nose and eyes, rubbing the body surface and spirit given to the oral cavity. The most notable stimulation was use of electricity, which was initiated by better understanding of its power by Benjamin Franklin and Luigi A. Galvani. Charles Kite developed the first electrical machine to stimulate the heart, and by 1800, it was found that the most effective site for applying electricity was over the heart.

Abstract
In the mid-18th century, a growing number of peo- ple started to attempt resuscitation of "apparently dead" people as a result of drowning or other causes. In this article, I describe the background for this movement (which was likely to be related to a fear of being buried alive and of being dissected alive). I also describe a historical development of rescue methods of drowned people.

Abstract
A variety of agents may have a beneficial effect in reducing injury-induced intestinal edema of fluid, but studies confirming the efficacy and mechanisms of these agents in secondary intra-abdominal hypertension (IAH) are lacking. This study was to compare the effectiveness of melatonin, 7.5% hypertonic saline (HS), and hydroxyethyl starch 130/0.4 (HES) on the resuscitation of secondary IAH in a rat model. Female SD rats were divided into: sham group, shock group, lactated Ringer solution (LR) group, melatonin group, HS group, and HES group. Except for the sham group, all rats underwent a combination of inducing portal hypertension, hemorrhaging to a MAP of 40 mmHg for 2 hr, and using an abdominal restraint device. The collected blood was reinfused and the rats were treated with LR (30ml/h), melatonin (50 mg/kg) + LR, HS (6 ml/kg) + LR, and HES (30 ml/kg) + LR, respectively. The shock group received no fluids. LR was continuously infused for 6hr. The intestinal permeability, immunofluorescence of tight junction proteins, transmission electron microscopy, level of inflammatory mediators (TNF-a, IL-1β, IL-6) and of biochemical markers of oxidative stress (malondialdehyde, myeloperoxidase activity, and glutathione peroxidase) were assessed. Expressions of the protein kinase B (Akt) and of tight junction proteins were detected by Western blot. Compared with LR, HS, and HES, melatonin was associated with less inflammatory and oxidative injury, less intestinal permeability and injury, and lower incidence of secondary IAH in this model. The salutary effect of melatonin in this model was associated with the upregulation of intestinal Akt phosphorylation.

Abstract
BACKGROUND Interventions to improve neonatal resuscitation are considered a priority for reducing neonatal mortality. In addition to training programs for health caregivers, the availability of adequate equipment in all delivery settings is crucial. In this study, we assessed the availability of equipment for neonatal resuscitation in a large sample of delivery rooms in Vietnam, exploring regional differences. METHODS In 2012, a structured questionnaire on 2011 neonatal resuscitation practice was sent to the heads of 187 health facilities, representing the three levels of hospital-based maternity services in eight administrative regions in Vietnam, allowing national and regional estimates to be calculated. RESULTS Overall the response rate was an 85.7 % (160/187 hospitals). There was a limited availability of equipment considered as "essential" in the surveyed centres: stethoscopes (68.0 %; 95 % CI: 60.3-75.7), clock (50.3 %; 42.0-58.7), clothes (29.5 %; (22.0-36.9), head covering (12.3 %; 7.2-17.4). The percentage of centres equipped with polyethylene bags (2.2 %; 0.0-4.6), pulse oximeter (9.4 %; 5.2-13.6) and room air source (1.9 %; 0.1-3.6) was very low. CONCLUSION Adequate equipment for neonatal resuscitation was not available in a considerable proportion of hospitals in Vietnam. This problem was more relevant in some regions. The assessment strategy used in this study could be useful for organizing the procurement and distribution of supplies and equipment in other low and/or middle resource settings.

Abstract
Aim To compare the influence of devices for manual ventilation and individual experience on the applied respiratory mechanics and sustained lung inflation. Methods A total of 114 instructors and non-instructors from the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics participated in this study. Participants ventilated an intubated manikin. To evaluate respiratory mechanics and sustained lung inflation parameters, a direct comparison was made between the self-inflating bag and the T-shaped resuscitator (T-piece), followed by an analysis of the effectiveness of the equipment according to the participants’ education and training. Results A difference between equipment types was observed for the tidal volume, with a median (interquartile range) of 28.5 mL (12.6) for the self-inflating bag and 20.1 mL (8.4) for the T-piece in the instructor group and 31.6 mL (14) for the self-inflating bag and 22.3 mL (8.8) for the T-piece in the non-instructor group. Higher inspiratory time values were observed with the T-piece in both groups of professionals, with no significant difference between them. The operator’s ability to maintain the target pressure over the 10 seconds of sustained lung inflation was evaluated using the area under the pressure-time curve and was 1.7-fold higher with the use of the T-piece. Inspiratory pressure and mean airway pressure applied during sustained lung inflation were greater with the self-inflating bag, as evaluated between the beginning and the end of the procedure. Conclusion The T-piece resulted in lower tidal volume and higher inspiratory time values, irrespective of the operator’s experience, and increased the ease of performing the sustained lung inflation maneuver, as demonstrated by the maintenance of target pressure for the desired period and a higher mean airway pressure than that obtained using the self-inflating bag.

Abstract
UNLABELLED Limited accessibility to resuscitation equipment and non-standardized instrument layout in trolleys would cause difficulty for the team members to access appropriate emergency equipment for delivering prompt resuscitation service in Tung Wah Eastern Hospital (TWEH). Improvement initiatives were implemented in September 2012 after endorsement by the resuscitation subcommittee: (i) standardization and installation of resuscitation equipment including resuscitation trolleys, emergency drug kits, automatic emergency defibrillators, designated response team (DRT) kit; (ii) guidelines revision involves the workflow, staff deployment, and designated areas for resuscitation during different service hours and (iii) staff training by workshop and video. Periodic resuscitation drill was held to monitor staff performance after training and the debriefing provided a chance for discussion and feedback from frontline staff. The compliance audit result for this exercise and the staff performance in the drills were improved, showing that the initiatives were successful.

Abstract
BACKGROUND In-water resuscitation (IWR) is recommended in the 2010 guidelines of the European Resuscitation Council. As IWR represents a physical challenge to the rescuer, a novel Rescue Tube device with an integrated "Oxylator" resuscitator might facilitate IWR. The aim of the present study was the assessment of IWR using the novel Rescue Tube device. METHODS Tidal and minute volumes were recorded using a modified Laerdal Resusci Anne mannequin. Furthermore, rescue time, water aspiration, submersions, and physical exertion were assessed. In this randomized cross-over trial, 17 lifeguards performed four rescue maneuvers over a 100-m distance in open water in random order: no ventilation (NV), mouth-to-mouth ventilation (MMV), Oxylator-aided mask ventilation (OMV), and Oxylator-aided laryngeal tube ventilation (OLTV). RESULTS OLTV resulted in effective ventilation over the entire rescue distance with the highest mean minute volumes (NV 0, MMV 2.9, OMV 4.1, OLTV 7.6 L · min(-1)). NV was the fastest rescue maneuver while IWR prolonged the rescue maneuver independently of the method of ventilation (mean total rescue time: NV 217, MMV 280, OMV 292, OLTV 290 s). Aspiration of substantial amounts of water occurred only during MMV (mean NV 20, MMV 215, OMV 15, OLTV 6 ml). NV and OLTV were rated as moderately challenging by the lifeguards, whereas MMV and OMV were rated as substantially demanding on a 0-10 visual analog scale (NV 5.3, MMV 7.8, OMV 7.6, OLTV 5.9). DISCUSSION The device might facilitate IWR by providing effective ventilation with minimal aspiration and by reducing physical effort. Another advantage is the possibility of delivering 100% oxygen.

Abstract
BACKGROUND Intraosseous access (IO) is a rapid and safe alternative when peripheral venous access is difficult. Our aim was to summarize the first three years experience with the use of a semi-automatic IO device (EZ-IO(®)) in German Helicopter Emergency Medical Service (HEMS). METHODS Included were all patients during study period (January 2009-December 2011) requiring an IO access performed by HEMS team. Outcome variables were IO rate, IO insertion success rates, site of IO access, type of EZ-IO(®) needle set used, strategy of vascular access, procedure related problems and operator's satisfaction. RESULTS IO rate was 0.3% (348/120.923). Overall success rate was 99.6% with a first attempt success rate of 85.9%; there was only one failure (0.4%). There were three insertion sites: proximal tibia (87.2%), distal tibia (7.5%) and proximal humerus (5.3%). Within total study group IO was predominantly the second-line strategy (39% vs. 61%, p<0.001), but in children<7 years, in trauma cases and in cardiac arrest IO was more often first-line strategy (64% vs. 28%, p<0.001; 48% vs. 34%, p<0.032; 50% vs. 29%, p<0.002 respectively). Patients with IO access were significantly younger (41.7±28.7 vs. 56.5±24.4 years; p<0.001), more often male (63.2% vs. 57.7%; p=0.037), included more trauma cases (37.3% vs. 30.0%; p=0.003) and more often patients with a NACA-Score≥5 rating (77.0% vs. 18.6%; p<0.001). Patients who required IO access generally presented with more severely compromised vital signs associated with the need for more invasive resuscitation actions such as intubation, chest drains, CPR and defibrillation. In 93% EZ-IO(®) needle set handling was rated "good". Problems were reported in 1.6% (needle dislocation 0.8%, needle bending 0.4% and parafusion 0.4%). CONCLUSIONS The IO route was generally used in the most critically ill of patients. Our relatively low rate of usage would indicate that this would be compatible with the recommendations of established guidelines. The EZ-IO(®) intraosseous device proved feasible with a high success rate in adult and pediatric emergency patients in HEMS.

Abstract
OBJECTIVE In neonatal resuscitation, the use of a sustained inflation (SI) may facilitate lung aeration. Previous studies comparing different resuscitation devices have shown that one model of self-inflating bag (SIB) could not deliver an SI. We aimed to compare the delivery of an SI using four SIBs with that of a T-piece. STUDY DESIGN In intubated preterm lambs, we compared four models of SIB fitted with a positive end expiratory pressure (PEEP) valve to a T-piece using a gas flow of 8 L/min. Four operators aimed to deliver three SIs of 20 cm H₂O for 30 s. The study was repeated with the PEEP valve removed and again with no flow. We measured duration of SI, average inflation pressure (IP) and analysed the shape of the pressure curves. RESULTS 204 combinations were analysed. Mean (SD) duration of SI was Ambu 6(2)s, Laerdal 14(8)s, Parker Healthcare 5(1)s, Mayo Healthcare 33(2)s and T-piece 33(1)s. Mean (SD) average IP was Ambu 17(3)cm H₂O, Laerdal 17(3)cm H₂O, Parker Healthcare 12(5)cm H₂O, Mayo Healthcare 21(2)cm H₂O and T-piece 20(0)cm H₂O. Duration of SI and average IP was significantly different between SIBs (all p<0.001). The findings were substantially unchanged when PEEP valve and flow were removed (all p>0.05). Only the Mayo system delivered SIs with duration and average IP not significantly different from the T-piece (p>0.05). CONCLUSIONS The performance of the four SIBs tested varied considerably. Some are able to deliver an SI even in the absence of gas flow. This may be useful in a resource-limited setting with no gas supply.

Abstract
BACKGROUND Undamaged medical gloves protect medical personnel from contact with physiological fluids of the patient. Thus they protect the assistance provider from hand skin contamination with potentially infectious biological materials. The aim of the study was to evaluate the occurrence of pierce, perforations or damage of medical gloves during cannulation of blood vessels. MATERIALS AND METHODS In the prospective randomized study 303 pairs of gloves, used during cannulation of blood vessels under simulated resuscitation, were analyzed. Gloves were tested by the water leak test. RESULTS The water test revealed 44 cases of damage to the gloves used during cannulation of blood vessels. Significant differences were noted in the frequency of damage to both the outer and single pairs of gloves and the inner pair of gloves. CONCLUSIONS The study showed that the use of double gloves provides a higher level of security for a paramedic than the use of a single pair of gloves, however, double gloves reduce the manual dexterity of a paramedic. A large number of damages to gloves are not noticed by medical personnel during surgery.

Abstract
INTRODUCTION In an operational military environment, circulatory access can prove difficult for a variety of reasons including profound hypovolaemia, and limited first responder experience. With many injuries that cause catastrophic haemorrhage, such as traumatic limb amputations, circulatory access is needed as quickly as possible. Since 2006, the Defence Medical Services have been using the EZ-IO and FAST1 devices as a means of obtaining circulatory access. METHODS A prospective observational study was conducted between March and July 2011 at the Emergency Department, Camp Bastion, Afghanistan. All patients with an intraosseous device had data recorded that included if the device successfully flushed (functionality) and if any problems were encountered. RESULTS 117 patients presented with a total of 195 devices: 149 were EZ-IO (76%) and 46 were FAST1 (24%). Functionality was recorded for 111 (57%), with 17 failing to function, yielding an overall success rate of 84.7%. Device failure was observed to be more prevalent in the humerus; inability to flush the device was the leading cause, followed by mechanical failure. There were 2 complications, device breaking on removal being the reason for both. CONCLUSIONS The devices in the study were tested for a period of time following insertion (median 32 minutes), and still the success rates mirror those found in the literature. Observed differences between sites were not found to be significant with confidence intervals overlapping. Further work is proposed to investigate the long-term complications of intraosseous devices.

Abstract
We examined configuring a radio frequency identification (RFID) equipment for the best object use detection in a trauma bay. Unlike prior work on RFID, we 1) optimized the accuracy of object use detection rather than just object detection; and 2) quantitatively assessed antenna placement while addressing issues specific to tag placement likely to occur in a trauma bay. Our design started with an analysis of the environment requirements and constraints. We designed several antenna setups with different number of components (RFID tags or antennas) and their orientations. Setups were evaluated under scenarios simulating a dynamic medical setting. We used three metrics with increasing complexity and bias: read rate, received signal strength indication distribution distance, and target application performance. Our experiments showed that antennas above the regions with high object density are most suitable for detecting object use. We explored tagging strategies for challenging objects so that sufficient readout rates are obtained for computing evaluation metrics. Among the metrics, distribution distance was correlated with target application performance, and also less biased and simpler to calculate, which made it an excellent metric for context-aware applications. We present experimental results obtained in the real trauma bay to validate our findings.

Abstract
INTRODUCTION In-water resuscitation has recently been proposed in the European resuscitation guidelines. Initiation of mechanical ventilation underwater might be considered when an immediate ascent to the surface is impossible or dangerous. The present study evaluated the feasibility of such ventilation underwater. METHODS A resuscitation manikin was ventilated using an Interspiro® MK II full-face mask or with an Oxylator® ventilator via a facemask or a laryngeal tube, or with mouth-to-tube inflation. Tidal volumes achieved by the individual methods of ventilation were assessed. The ventilation tests were performed during dives in the wet compartment of a recompression chamber and in a lake. Ventilation was tested at 40, 30, 20, 12, 9 and 6 metres' depth. RESULTS Ventilation was impossible with the cuffed mask and only sufficient after laryngeal intubation for a small number of breaths. Laryngeal tube ventilation was associated with the aspiration of large amounts of water and the Oxylator failed during the ascent. Efficient ventilation with the MK II full-face mask was also possible only for a short period. An absolutely horizontal position of the manikin was required for successful ventilation, which is likely to be difficult to achieve in open water. Leakage at the sealing lip of the full-face mask and the cuff of the laryngeal tube led to intrusion of water and resulted in subsequent complete failure of ventilation. CONCLUSIONS The efficacy of underwater ventilation seems to be poor with any of the techniques trialed. Water aspiration frequently makes ventilation impossible and might foster emphysema aquosum-like air trapping and, therefore, increase the risk of pulmonary barotrauma during ascent. Because the limitations of underwater ventilation are substantial even under ideal conditions, it cannot be recommended presently for real diving conditions.

Walker ST, Brett SJ, McKay A, Aggarwal R, Vincent C. The "Resus:Station": the use of clinical simulations in a randomised crossover study to evaluate a novel resuscitation trolley. Resuscitation 2012; 83:1374-80.

Abstract
BACKGROUND AND AIM Inadequately designed equipment has been implicated in poor efficiency and critical incidents associated with resuscitation. A novel resuscitation trolley (Resus:Station) was designed and evaluated for impact on team efficiency, user opinion, and teamwork, compared with the standard trolley, in simulated cardiac arrest scenarios. METHODS Fifteen experienced cardiac arrest teams were recruited (45 participants). Teams performed recorded resuscitation simulations using new and conventional trolleys, with order of use randomised. After each simulation, efficiency ("time to drugs", un-locatable equipment, unnecessary drawer opening) and team performance (OSCAR) were assessed from the video recordings and participants were asked to complete questionnaires scoring various aspects of the trolley on a Likert scale. RESULTS Time to locate the drugs was significantly faster (p=0.001) when using the Resus:Station (mean 5.19s (SD 3.34)) than when using the standard trolley (26.81s (SD16.05)). There were no reports of missing equipment when using the Resus:Station. However, during four of the fifteen study sessions using the standard trolley participants were unable to find equipment, with an average of 6.75 unnecessary drawer openings per simulation. User feedback results clearly indicated a highly significant preference for the newly designed Resus:Station for all aspects. Teams performed equally well for all dimensions of team performance using both trolleys, despite it being their first exposure to the Resus:Station. CONCLUSION We conclude that in this simulated environment, the new design of trolley is safe to use, and has the potential to improve efficiency at a resuscitation attempt.

Abstract
OBJECTIVE To reduce airway injury secondary to high suction pressures, the American Academy of Pediatrics Neonatal Resuscitation Program (NPR) recommends that suction pressures be less than 100 mm Hg. This study was conducted to determine if suction bulbs conform to these recommendations. STUDY DESIGN In this prospective in vitro study, 25 personnel involved in neonatal resuscitation squeezed a new bulb three times for each of six commercially available bulbs using their delivery suite technique. A calibrated, pneumatic transducer measured the pressure of each squeeze. RESULTS Only one bulb met the NRP guidelines with none of the participants exceeding 100mm Hg (p<0.001). CONCLUSIONS Only one bulb met the NRP guidelines of generating pressures less than 100 mm Hg. This bulb's large size (3 oz) may preclude its use in premature infants. Individuals involved in resuscitating newborns need to be aware of the pressures generated to avoid injuring the delicate oral airway.
