Trauma patient transport to hospital using helicopter emergency medical services or road ambulance in Sweden: a comparison of survival and prehospital time intervals. Scand J Trauma Resusc Emerg Med 2023; 31:101. [PMID: 38104083 PMCID: PMC10725597 DOI: 10.1186/s13049-023-01168-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 12/08/2023] [Indexed: 12/19/2023] Open
Abstract
BACKGROUND The benefits of helicopter emergency medical services (HEMS) transport of adults following major trauma have been examined with mixed results, with some studies reporting a survival benefit compared to regular emergency medical services (EMS). The benefit of HEMS in the context of the Swedish trauma system remains unclear. AIM To investigate differences in survival and prehospital time intervals for trauma patients in Sweden transported by HEMS compared to road ambulance EMS. METHODS A total of 74,032 trauma patients treated during 2012-2022 were identified through the Swedish Trauma Registry (SweTrau). The primary outcome was 30-day mortality and Glasgow Outcome Score at discharge from hospital (to home or rehab); secondary outcomes were the proportion of severely injured patients who triggered a trauma team activation (TTA) on arrival to hospital and the proportion of severely injured patients with GCS ≤ 8 who were subject to prehospital endotracheal intubation. RESULTS 4529 out of 74,032 patients were transported by HEMS during the study period. HEMS patients had significantly lower mortality compared to patients transported by EMS at 1.9% vs 4.3% (ISS 9-15), 5.4% vs 9.4% (ISS 16-24) and 31% vs 42% (ISS ≥ 25) (p < 0.001). Transport by HEMS was also associated with worse neurological outcome at discharge from hospital, as well as a higher rate of in-hospital TTA for severely injured patients and higher rate of prehospital intubation for severely injured patients with GCS ≤ 8. Prehospital time intervals were significantly longer for HEMS patients compared to EMS across all injury severity groups. CONCLUSION Trauma patients transported to hospital by HEMS had significantly lower mortality compared to those transported by EMS, despite longer prehospital time intervals and greater injury severity. However, this survival benefit may have been at the expense of a higher degree of adverse neurological outcome. Increasing the availability of HEMS to include all regions should be considered as it may be the preferrable option for transport of severely injured trauma patients in Sweden.

Eur J Pediatr 2023; 182:5057-5065. [PMID: 37656240 PMCID: PMC10640406 DOI: 10.1007/s00431-023-05178-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/15/2023] [Accepted: 08/23/2023] [Indexed: 09/02/2023]
Abstract
This study primarily aims to determine the frequency of life-threatening conditions among pediatric patients served by the DRF, a German helicopter emergency service (HEMS) provider. It also seeks to explore the necessity of invasive procedures in this population, discussing the implications for HEMS crew training and service configuration based on current literature. We analyzed the mission registry from 31 DRF helicopter bases in Germany, focusing on 7954 children aged 10 or younger over a 5-year period (2014-2018). Out of 7954 identified children (6.2% of all primary missions), 2081 (26.2%) had critical conditions. Endotracheal intubation was needed in 6.5% of cases, while alternative airway management methods were rare (n = 14). Half of the children required intravenous access, and 3.6% needed intraosseous access. Thoracostomy thoracentesis and sonography were only performed in isolated cases. Conclusions: Critically ill or injured children are infrequent in German HEMS operations. Our findings suggest that the likelihood of HEMS teams encountering such cases is remarkably low. Besides endotracheal intubation, life-saving invasive procedures are seldom necessary. Consequently, we conclude that on-the-job training and mission experience alone are insufficient for acquiring and maintaining the competencies needed to care for critically ill or injured children. What is Known: • Pediatric emergencies are relatively rare in the prehospital setting, but their incidence is higher in helicopter emergency medical services (HEMS) compared to ground-based emergency services. What is New: • On average, HEMS doctors in Germany encounter a critically ill or injured child approximately every 1.5 years in their practice, establish an IV or IO access in infants or toddlers every 2 years, and intubate an infant every 46 years. • This low frequency highlights the insufficiency of on-the-job training alone to develop and maintain pediatric skills among HEMS crews. Specific interdisciplinary training for HEMS crews is needed to ensure effective care for critically unwell pediatric patients.

Abstract
Ketamine is a racemic mixture of equal amounts of R-ketamine and S-ketamine and is well known to anesthesiologists for its unique dissociative anesthetic properties. The pharmacological properties of ketamine, namely, its sympathetic excitation, mild respiratory depression, and potent analgesia, are still highly valued in its use as an anesthetic for some patients. In particular, since its advent, S-ketamine has been widely used as an anesthetic in many countries due to its increased affinity for NMDA receptors and its enhanced anesthetic and analgesic effects. However, the anesthetic and analgesic mechanisms of S-ketamine are not fully understood. In addition to antagonizing NMDA receptors, a variety of other receptors or channels may be involved, but there are no relevant mechanistic summaries in the literature. Therefore, the purpose of this paper is to review the mechanisms of action of S-ketamine on relevant receptors and systems in the body that result in its pharmacological properties, such as anesthesia and analgesia, with the aim of providing a reference for its clinical applications and research.

Abstract
Children who sustain major injuries are at risk of receiving insufficient pain relief and sedation, which can have physical and psychological repercussions. Heightened emotional distress can increase the likelihood of developing symptoms of post-traumatic stress. Providing sufficient analgesia and sedation for children with major trauma presents specific challenges, given the potential for drug-related adverse events, particularly in non-intubated patients. The current literature suggests that a relatively low percentage of pediatric patients receive adequate analgesia in pre-hospital and emergency department settings following major trauma. There are only sparse data on the safety of the provision of analgesia and sedation in children with major trauma in the pre-hospital and ED settings. The few studies that examined sedation protocols in this context highlight the importance of physician training and competency in managing pediatric airways. There is a pressing need for prospective studies that focus upon pediatric major trauma in the pre-hospital and emergency department setting to evaluate the benefits and risks of administering analgesia and sedation to these patients. The aim of this narrative review was to offer an updated overview of analgesia and sedation management in children with major trauma in pre-hospital and ED settings.

Factors influencing on-scene time in a physician-staffed helicopter emergency medical service (HEMS): a retrospective observational study. Scand J Trauma Resusc Emerg Med 2023; 31:20. [PMID: 37060088 PMCID: PMC10105469 DOI: 10.1186/s13049-023-01085-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 04/06/2023] [Indexed: 04/16/2023] Open
Abstract
BACKGROUND For helicopter emergency service systems (HEMS), the prehospital time consists of response time, on-scene time and transport time. Little is known about the factors that influence on-scene time or about differences between adult and paediatric missions in a physician-staffed HEMS. METHODS We analysed the HEMS electronic database of Swiss Air-Rescue from 01-01-2011 to 31-12-2021 (N = 110,331). We included primary missions and excluded missions with National Advisory Committee for Aeronautics score (NACA) score 0 or 7, resulting in 68,333 missions for analysis. The primary endpoint 'on-scene time' was defined as first physical contact with the patient until take-off to the hospital. A multivariable linear regression model was computed to examine the association of diagnosis, type and number of interventions and monitoring, and patient's characteristics with the primary endpoint. RESULTS The prehospital time and on-scene time of the missions studied were, respectively, 50.6 [IQR: 41.0-62.0] minutes and 21.0 [IQR: 15.0-28.6] minutes. Helicopter hoist operations, resuscitation, airway management, critical interventions, remote location, night-time, and paediatric patients were associated with longer on-scene times. CONCLUSIONS Compared to adult patients, the adjusted on-scene time for paediatric patients was longer. Besides the strong impact of a helicopter hoist operation on on-scene time, the dominant factors contributing to on-scene time are the type and number of interventions and monitoring: improving individual interventions or performing them in parallel may offer great potential for reducing on-scene time. However, multiple clinical interventions and monitoring interact and are not single interventions. Compared to the impact of interventions, non-modifiable factors, such as NACA score, type of diagnosis and age, make only a minor contribution to overall on-scene time.

Diseases 2023; 11:diseases11010045.

Abstract
Trauma is a major cause of mortality throughout the world. Traumatic pain—acute, sudden, or chronic—is defined as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage”. Patients’ perceptions of pain assessment and management have become an important criterion and relevant outcome measure for healthcare institutions. Several studies show that 60–70% of ER patients experience pain, and more than half of them express a feeling of sorrow, which can be moderate or severe, at triage. The few studies that have analyzed how pain is assessed and managed in these departments agree that approximately 70% of patients receive no analgesia or receive it with remarkable delay. Specifically, less than half of the patients receive treatment for pain during admission and 60% of discharged patients have higher intensity pain than at admission. Trauma patients are also the ones who most commonly report low satisfaction with pain management. Associated with this lack of satisfaction, we can describe the poor use of tools for measuring and recording pain, poor communication among caregivers, inadequate training in pain assessment and management, and widespread misconceptions among nurses about the reliability of patients’ estimation of pain. The aim of this article is to review the scientific literature to explore the methodologies of pain management in trauma patients attending the emergency room and analyzing their weaknesses as a starting point to improve the approach to this, unfortunately too often, underestimated issue. A literature search was performed using the major databases to identify relevant studies in indexed scientific journals. The literature showed that the multimodal approach in trauma patients is the best approach to pain management. It is becoming increasingly crucial to manage the patient on multiple fronts. Drugs acting on different pathways can be administered together at lower doses, minimizing risks. Every emergency department must have staff trained in the assessment and immediate management of pain symptoms as this allows the reduction of mortality and morbidity and shortens hospital stays, contributing to early mobilization, reduced hospital costs, and enhanced patient satisfaction and quality of life.

Abstract
BACKGROUND Pain management in the pre-hospital setting remains a particular challenge for paramedics and emergency physicians, especially in children. This study evaluates the pre-hospital use and effect of analgesics in children with trauma or pain due to other reasons. METHODS This study is a retrospective analysis of the database of a German air rescue service and was conducted over a period of 9 years (2012-2020) to assess pain in general and whether patients with trauma pain due to other reasons received treatment with analgesics. We included all patients in the registry under the age of 16 years. Patients with a Glasgow Coma Scale of 3 at hospital admission and incomplete records were excluded. The intensity of pain was determined by the emergency physician on scene at arrival and hospital admission in a ten-point rating scale (0 = no pain). Effective pain reduction was analyzed. RESULTS Out of 227,458 cases, a total of 22,025 emergency cases involved pediatric patients aged 0-16 years. 20,405 cases were included in the study. 12,000 (58.8%) children had suffered a trauma, 8108 (39.7%) had pain due to other reasons and 297 (1.5%) had both. In total, 4,608 (38.4%) of the children with trauma were assessed having a numerical rating scale (NRS) > 4 at EMS arrival. These patients received mainly ketamine (34.5%) and the opioids fentanyl (38.7%) and piritramide (19.1%). The value on the NRS was significantly lower at admission to hospital (mean 1.9) compared with the EMS arrival (mean 6.9). In 4.9% the NRS at hospital admission was still > 4. 282 patients within the non-trauma group had a pre-hospital NRS of > 4. The pain therapy consisted of opioids (35.8%) and ketamine (2.8%). 28.4% patients in the non-trauma group received no pain medication. In 16.0% the NRS at hospital admission was still > 4. CONCLUSIONS German emergency physicians achieved a sufficient pain therapy in pediatric patients with a NRS > 4 after trauma. In case of non-trauma, the pain management by the emergency physicians is restrained and less successful. The most common analgesic medications administered were ketamine and fentanyl, followed by piritramide. TRIAL REGISTRATION The study has been retrospectively registered at DRKS (DRKS00026222).
