“…Nevertheless, we expect cancellations due to weather to decrease as our flight crews become more familiar and confident with our topography and regional weather patterns. The increasing implementation of technology such as GPS approach systems and weather webcam systems may increase efficacy [ 26 ].…”

BackgroundPhysician-staffed helicopter emergency services (HEMS) can provide benefit through the delivery of specialist competence and equipment to the prehospital scene and through expedient transport of critically ill patients to specialist care. This paper describes the integration of such a system in a rural Swedish county.MethodsThis is a retrospective database study recording the outcomes of every emergency call centre dispatch request as well as the clinical and operational data from all completed missions during this service’s first year in operation.ResultsDuring the study period, HEMS completed 478 missions out of which 405 (84,7%) were primary missions to prehospital settings and 73 (15,3%) were inter-hospital critical care transfers. A majority (55,3%) of primary missions occurred in the regions furthest from our hospitals, in municipalities housing only 15,6% of the county’s population. The NACA (IQR) score on primary and secondary missions was 4 (2) and 5 (1), respectively.ConclusionsThis study describes the successful integration of a physician-based air ambulance service in a Scandinavian rural region. Municipalities distant from our hospitals benefitted as they now have access to early specialist intervention and expedient transport to critical hospital care. Our hospitals and most populated areas benefitted from HEMS secondary mission capability as they gained a dedicated ICU transport service that could provide specialist intensive care during rapid inter-hospital transfer.

“…The helicopter on stand-by at our institution can dispatch within 5 min after a request and reach a 110-km remote distance within 30 min as previously reported (10,11). Doctors and nurses board each ight to administer prehospital medicine and determine the facility to which the patient should be transported.…”

“…As the system improved survival after major trauma (16) and increased the indication for thrombolytic therapy in cerebral infarction (17), the application of prehospital medicine beginning early after injury and rapid transport notably contributed to the early reduction of cervical spine dislocations and neurological recovery in the present study. Helicopter transport has been reported to have an impact on rapid admission for distances greater than 16 km (18); moreover, it reduces regional differences in medical care (8), such as in rural Japan, where limited hospitals can be consolidated (10,11,19).…”

Background Several clinical and basic studies have shown that an association exists between achieving decompression of the spinal cord within a few hours and neurological recovery, even in patients with complete paralysis due to cervical spine dislocation. This study aimed to clarify the impact of helicopter emergency medical services(HEMS)and craniocervical traction using a halo ring on rapid reduction of lower cervical spine dislocation in rural Japan. Methods The success rate of and factors inhibiting closed reduction, time from injury to reduction and functional prognosis of lower cervical spine dislocations treated between July 2012 and January 2020 were retrospectively analysed. Results Fourteen patients were transported by HEMS (group H), seven were by ambulances (group A) and two were by themselves. Although the average travelled distance and injury severity score were significantly higher in group H (64.5 km, 28.0) than in group A (24.7 km, 18.6), there was no significant difference in the average time to admission or the time to start craniocervical traction after admission between group H (159.4 min, 52.2 min) and group A (163.6 min, 53.2 min). The urgent traction could be administered for 20 patients. The success rate of closed reduction was 95%, and neurological deterioration following traction was not observed in any cases. The average traction time and weight for reduction were 30.3 min and 16.3 kg, respectively. Patients’ body size and fracture-dislocation types did not significantly affect the traction time or weight. The rate of reduction within 4 h after injury was higher in group H (79%) than in group A (33%). Herniated discs were found at dislocation levels in five patients by magnetic resonance imaging scans performed after closed reduction, and all cases of inner fixation were treated via the posterior approach an average of 5.7 days after admission. After these treatment, three of nine AIS A patients recovered the ability to walk, and all the three patients underwent successful closed reduction within 4 h after injury. Conclusion HEMS and highly successful closed reduction considerably contributed to the early reduction of cervical spine dislocation and can potentially improve complete paralysis.
