Evaluation of resuscitation with angiography, percutaneous techniques and operative repair (RAPTOR): hybrid suite introduction and initial use at a level I urban trauma centre.

The aim of this study was to describe the utilization of the RAPTOR suite (hybrid theatre) for trauma patients. Ideally, this is used to achieve haemorrhage control in time-critical patients that may require damage control surgery (DCS) and/or interventional radiological (IR) procedures concurrently. A single-centre, retrospective study identifying all trauma patients that were treated at the level I trauma centre during 2011-2016 was performed. Patients that underwent treatment in the RAPTOR suite were described. Subgroup analyses were performed for trauma patients that underwent interventions within 60min and patients who underwent a combination of DCS + angioembolization in the RAPTOR suite or in other locations (OR, radiology). Since its introduction in 2011, 1% of all procedures performed in the RAPTOR suite were trauma related. From 2011 until 2016, 43 trauma patients underwent treatment in the RAPTOR suite. The majority of patients (81%) suffered blunt injury. Most patients were male (70%), with a mean age of 43years. The mean ISS was 38. In 56% (n = 24) the MTP was activated and in 40% (n = 17) a CT scan was performed prior to treatment. Damage control surgery alone, angioembolization alone and a combination of DCS and angioembolization were performed in 37% (n = 16), 23% (n = 10) and 40% (n = 17) of patients, respectively. Median time to the hybrid suite, procedure time and total time were 56min (15-704), 160min (42-404), and 251min (93-788), respectively. In the first 5years following introduction of a hybrid theatre in an urban level I trauma centre, only 1% of patients using the resource has injury-related pathology. Earlier identification of patients requiring this facility may improve timely access and management for this select group of patients needing urgent control of bleeding.

Effects of Early Altitude Exposure on the Open Abdomen After Laparotomy in Trauma.

While damage control surgery and resuscitation techniques have revolutionized the care of injured service members who sustain severe traumatic hemorrhage, the physiologic and inflammatory consequences of hemostatic resuscitation and staged abdominal surgery in the face of early aeromedical evacuation (AE) have not been investigated. We hypothesized that post-injury AE with an open abdomen would have significant physiologic and inflammatory consequences compared to AE with a closed abdomen. Evaluation of resuscitation and staged abdominal closure was performed using a murine model of hemorrhagic shock with laparotomy. Mice underwent controlled hemorrhage to a systolic blood pressure of 25 mmHg and received either no resuscitation, blood product resuscitation, or Hextend resuscitation to a systolic blood pressure of either 50 mmHg (partial resuscitation) or 80 mmHg (complete resuscitation). Laparotomies were either closed prior to AE (closed abdomens) or left open during AE (open abdomens) and subsequently closed. AE was simulated with a 1-hour exposure to a hypobaric hypoxic environment at 8,000 feet altitude. Mice were euthanized at 0, 4, or 24 hours following AE. Serum was collected and analyzed for physiologic variables and inflammatory cytokine levels. Samples of lung and small intestine were collected for tissue cytokine and myeloperoxidase analysis as indicators of intestinal inflammation. Survival curves were also performed. Unresuscitated mice sustained an 85% mortality rate from hemorrhage and laparotomy, limiting the assessment of the effect of simulated AE in these subgroups. Overall survival was similar among all resuscitated groups regardless of the presence of hypobaric hypoxia, type of resuscitation, or abdominal closure status. Simulated AE had no observed effects on acid/base imbalance or the inflammatory response as compared to ground level controls. All mice experienced both metabolic acidosis and an acute inflammatory response after hemorrhage and injury, represented by an initial increase in serum interleukin (IL)-6 levels. Furthermore, mice with open abdomens had an elevated inflammatory response with increased levels of serum IL-10, serum tumor necrosis factor alpha, intestinal IL-6, intestinal IL-10, and pulmonary myeloperoxidase. These results demonstrate the complex interaction of AE and temporary or definitive abdominal closure after post-injury laparotomy. Contrary to our hypothesis, we found that AE in those animals with open abdomens is relatively safe with no difference in mortality compared to those with closed abdomens. However, given the physiologic and inflammatory changes observed in animals with open abdomens, further evaluation is necessary prior to definitive recommendations regarding the safety or downstream effects of exposure to AE prior to definitive abdominal closure.

Helping Babies Breathe (HBB) training: What happens to knowledge and skills over time?

BackgroundThe first minutes after birth are critical to reducing neonatal mortality. Helping Babies Breathe (HBB) is a simulation-based neonatal resuscitation program for low resource settings. We studied the impact of initial HBB training followed by refresher training on the knowledge and skills of the birth attendants in facilities.MethodsWe conducted HBB trainings in 71 facilities in the NICHD Global Network research sites (Nagpur and Belgaum, India and Eldoret, Kenya), with a 6:1 ratio of facility trainees to Master Trainers (MT). Because of staff turnover, some birth attendants (BA) were trained as they joined the delivery room staff, after the initial training was completed (catch-up initial training). We compared pass rates for skills and knowledge pre- and post- initial HBB training and following refresher training among active BAs. An Objective Structured Clinical Examination (OSCE) B tested resuscitation skill retention by comparing post-initial training performance with pre-refresher training performance. We identified factors associated with loss of skills in pre-refresher training performance using multivariable logistic regression analysis. Daily bag and mask ventilation practice, equipment checks and supportive supervision were stressed as part of training.ResultsOne hundred five MT (1.6 MT per facility) conducted initial and refresher HBB trainings for 835 BAs; 76% had no prior resuscitation training. Initial training improved knowledge and skills: the pass percentage for knowledge tests improved from 74 to 99% (p < 0.001). Only 5% could ventilate a newborn mannequin correctly before initial training but 97% passed the post-initial ventilation training test (p < 0.0001) and 99% passed the OSCE B resuscitation evaluation. During pre-refresher training evaluation, a mean of 6.7 (SD 2.49) months after the initial training, 99% passed the knowledge test, but the successful completion rate fell to 81% for the OSCE B resuscitation skills test. Characteristics associated with deterioration of resuscitation skills were BAs from tertiary care facilities, no prior resuscitation training, and the timing of training (initial vs. catch-up training).ConclusionsHBB training significantly improved neonatal resuscitation knowledge and skills. However, skills declined more than knowledge over time. Ongoing skills practice and monitoring, more frequent retesting, and refresher trainings are needed to maintain neonatal resuscitation skills.Trial registrationClinicalTrials.gov Identifier: NCT01681017; 04 September 2012, retrospectively registered.Electronic supplementary materialThe online version of this article (doi:10.1186/s12884-016-1141-3) contains supplementary material, which is available to authorized users.

The Evaluation of Resuscitation and Critical Care Equipment: A Quality Assurance Service for the User

Several thousand distinct medical devices exist and for each one the user usually has a choice from among a number of manufacturers. The process whereby a clinician or hospital purchasing agent makes a selection from a number of competing brands may be based on anything from, on the one extreme, little more than an emotional attraction to a particular brand name to, at the other end of the spectrum, a fully enlightened choice after an inhouse evaluation together with extensive additional information. This paper will describe, with concrete examples drawn from the ensemble of equipment used in the fields of resuscitation and critical care, how Emergency Care Research Institute evaluates such devices, investigates hazards associated with these instruments, and communicates this information to users.

Evaluation of resuscitation from cardiopulmonary arrest by paramedics

A series of 100 consecutive victims of cardiopulmonary arrest were evaluated for treatment in the field by paramedic teams and for the patients' subsequent course. Analysis of the data correlated success rates with specific factors, including response, treatment and transportation times, proximity to the emergency center, establishment of an intravenous line and administration of drugs, pulmonary aspiration of gastric contents, cardiopulmonary resuscitation by a bystander, cardiopulmonary arrest in the presence of the team, and other factors. Successful resuscitation was accomplished in 24% of cases, and 7% of the victims ultimately returned to their previous lifestyles. Therapeutic maneuvers which prolonged time at the scene worsened prognosis. These results were compared to recent reports from other institutions with specific reference to differences in technique regarding success rates. Although the basic policy of "rush the patient to the hospital" of past years has shifted to one of evaluation, emergency treatment and stabilization at the scene before transportation, the data suggest that specific guidelines consistent with the urgency of the situation are necessary to maximize the patient salvage rate.
