Proceedings of resources for optimal care of acute care and emergency surgery consensus summit Donegal Ireland.

BACKGROUND: Opportunities to improve emergency surgery outcomes exist through guided better practice and reduced variability. Few attempts have been made to define optimal care in emergency surgery, and few clinically derived key performance indicators (KPIs) have been published. A summit was therefore convened to look at resources for optimal care of emergency surgery. The aim of the Donegal Summit was to set a platform in place to develop guidelines and KPIs in emergency surgery. METHODS: The project had multidisciplinary global involvement in producing consensus statements regarding emergency surgery care in key areas, and to assess feasibility of producing KPIs that could be used to monitor process and outcome of care in the future. RESULTS: Forty-four key opinion leaders in emergency surgery, across 7 disciplines from 17 countries, composed evidence-based position papers on 14 key areas of emergency surgery and 112 KPIs in 20 acute conditions or emergency systems. CONCLUSIONS: The summit was successful in achieving position papers and KPIs in emergency surgery. While position papers were limited by non-graded evidence and non-validated KPIs, the process set a foundation for the future advancement of emergency surgery.

Validation of the VBLaST peg transfer task: a first step toward an alternate training standard.

BACKGROUND: The FLS trainer lacks objective and automated assessments of laparoscopic performance and requires a large supply of relatively expensive consumables. Virtual reality simulation has a great potential as a training and assessment tool of laparoscopic skills and can overcome some limitations of the FLS trainer. This study was carried out to assess the value of our Virtual Basic Laparoscopic Surgical Trainer (VBLaST(©)) in the peg transfer task compared to the FLS trainer and its ability to differentiate performance between novice, intermediate, and expert groups. METHODS: Thirty subjects were divided into three groups: novices (PGY1-2, n = 10), intermediates (PGY3-4, n = 10), and experts (PGY5, surgical fellows and attendings, n = 10). All subjects performed ten trials of the peg transfer task on each simulator. Assessment of laparoscopic performance was based on FLS scoring while a questionnaire was used for subjective evaluation. RESULTS: The performance scores in the two simulators were correlated, though subjects performed significantly better in the FLS trainer. Experts performed better than novices only on the FLS trainer while no significant differences were observed between the other groups. Moreover, a significant learning effect was found on both trainers, with a greater improvement of performance on the VBLaST(©). Finally, 82.6% of the subjects preferred the FLS over the VBLaST(©) for surgical training which could be attributed to the novelty of the VR technology and existing deficiencies of the user interface for the VBLaST(©). CONCLUSION: This study demonstrated that the VBLaST(©) reproduced faithfully some aspects of the FLS peg transfer task (such as color, size, and shape of the peg board, etc.) while other aspects require additional development. Future improvement of the user interface and haptic feedback will enhance the value of the system as an alternative to the FLS as the standard training tool for laparoscopic surgery skills.

Fifty-four emergent cricothyroidotomies: are surgeons reluctant teachers?

BACKGROUND: Emergent cricothyroidotomy remains an uncommon, but life-saving, core procedural training requirement for emergency medicine (EM) physician training. We hypothesized that, although most cricothyroidotomies occur in the emergency department (ED), they are rarely performed by EM physicians. METHODS: We conducted a retrospective analysis of all emergent cricothyroidotomies performed at two large level one trauma centers over 10 years. Operators and assistants for all procedures were identified, as well as mechanism of injury and patient demographics were examined. RESULTS: Fifty-four cricothyroidotomies were performed. Patients were: mean age of 50, 80% male and 90% blunt trauma. The most common primary operator was a surgeon (n = 47, 87%), followed by an Emergency Medical Services (EMS) provider (n = 6, 11%) and a EM physician (n = 1, 2%). In all cases, except those performed by EMS, the operator or assistant was an attending surgeon. All EMS procedures resulted in serious complications compared to in-hospital procedures (p < 0.0001). CONCLUSIONS: 1. Pre-hospital cricothyroidotomy results in serious complications. 2. Despite the ubiquitous presence of emergency medicine physicians in the ED, all crico-thyroidotomies were performed by a surgeon, which may represent a serious emergency medicine training deficiency.

Increased platelet:RBC ratios are associated with improved survival after massive transfusion.

BACKGROUND: Several recent military and civilian trauma studies demonstrate that improved outcomes are associated with early and increased use of plasma-based resuscitation strategies. However, outcomes associated with platelet transfusions are poorly characterized. We hypothesized that increased platelet:red blood cells (RBC) ratios would decrease hemorrhagic death and improve survival after massive transfusion (MT). METHODS: A transfusion database of patients transported from the scene to 22 Level I Trauma Centers over 12 months in 2005 to 2006 was reviewed. MT was defined as receiving ≥ 10 RBC units within 24 hours of admission. To mitigate survival bias, 25 patients who died within 60 minutes of arrival were excluded from analysis. Six random donor platelet units were considered equal to a single apheresis platelet unit. Admission and outcome data associated with the low (>1:20), medium (1:2), and high (1:1) platelet:RBC ratios were examined. These groups were based on the median value of the tertiles for the ratio of platelets:RBC units. RESULTS: Two thousand three hundred twelve patients received at least one unit of blood and 643 received an MT. Admission vital signs, INR, temperature, pH, Glasgow Coma Scale, Injury Severity Score, and age were similar between platelet ratio groups. The average admission platelet counts were lower in the patients who received the high platelet:RBC ratio versus the low ratio (192 vs. 216, p = 0.03). Patients who received MT were severely injured, with a mean (± standard deviation) Injury Severity Score of 33 ± 16 and received 22 ± 15 RBCs and 11 ± 14 platelets within 24 hours of injury. Increased platelet ratios were associated with improved survival at 24 hours and 30 days (p < 0.001 for both). Truncal hemorrhage as a cause of death was decreased (low: 67%, medium: 60%, high: 47%, p = 0.04). Multiple organ failure mortality was increased (low: 7%, medium: 16%, high: 27%, p = 0.003), but overall 30-day survival was improved (low: 52%, medium: 57%, high: 70%) in the high ratio group (medium vs. high: p = 0.008; low vs. high: p = 0.007). CONCLUSION: Similar to recently published military data, transfusion of platelet:RBC ratios of 1:1 was associated with improved early and late survival, decreased hemorrhagic death and a concomitant increase in multiple organ failure-related mortality. Based on this large retrospective study, increased and early use of platelets may be justified, pending the results of prospective randomized transfusion data.

Orofacial trauma and mouth-protector wear among high school varsity basketball players.

This investigation surveyed the prevalence and types of orofacial injuries among 1020 Florida high school basketball players during one season; it also examined the prevalence and types of mouth protectors used and their influence on sustained injuries. The results demonstrated a relatively high prevalence of players (31 percent) reporting orofacial trauma suffered during the organized playing of basketball. Most players reporting orofacial trauma indicated they received multiple injuries during the season. Only a small percentage (4.2 percent) of the basketball players surveyed reported use of mouth protectors and this use was exclusively voluntary. Those players not wearing mouth protectors reported an approximately seven-fold increase in orofacial injuries; most involved trauma to the soft tissue. Many objections were cited to the use of mouth protectors by the players, which must be overcome if compliance with future mandatory wear is recommended. Results of this survey suggest that further investigation into orofacial injuries among basketball players should be pursued.
