“…This is in line with reports describing that the capacity for implicit (sequential) learning decreases beyond the age of 45 yr. 27 Although females showed better overall performance with procedural learning tasks, their rate of learning was equivalent to males. 28 Our results are in concert with these findings (Fig. 3b).…”

Background: Cannot intubate-cannot ventilate situations in healthy children are uncommon but are often associated with poor outcome. Several airway management algorithms suggest emergency tracheal access. Little agreement exists on how to perform emergency front of the neck access (eFONA) in children <8 yr. We studied the learning curves of clinicians performing simulated paediatric eFONA. Methods: After watching an instructional video, 50 physicians, from five medical specialties, performed 10 emergency tracheotomies on rabbit cadavers. We analysed their learning curves relative to performance time and concurring injuries. Results: With an overall success rate of 94%, performance time decreased from 107 s (standard deviation [SD], 45) to 55 s (SD 17) over 10 attempts. The learning curve was steep between the first and the fourth attempts with an 11% decrease in performance time (95% confidence interval [CI], 9e13%; P<0.001) per attempt and then flattened to a 4% (95% CI, 3e5%; P<0.001) decrease per attempt between the fourth and the tenth attempt. Age, years of clinical experience, and sex showed a significant effect on the learning curve, whereas medical specialty and adult eFONA experience did not. The 58% (95% CI, 44e72%) probability for severe injury during the first attempt decreased to 14% (95% CI, 8e20%) at the second attempt. Men were more likely to cause minor injuries than women (P<0.001). Conclusions: Irrespective of medical specialty, paediatric clinicians acquired the eFONA technique within four attempts and were on average able to establish an airway in <1 min when performing emergency tracheotomy on a paediatric airway simulator. Clinical trial registration: NCT03576352.

“…Therefore, a possible approach to study the influence of the length of the learning course may be to spread the learning over several sessions. Furthermore, other aspects worth studying are gender effects, recently reported to play a critical role in ISL of male and female veterans who had sustained TBI (Waltzman et al, 2017). Finally, long-term effects of TBI and the influence of targeted interventions on ISL, are additional relevant questions to be investigated, since their outcome may be highly important in terms of being implemented in clinical settings and/or daily routines of individuals post TBI.…”

Objective: We investigated the effect of traumatic brain injury (TBI) on implicit sequence learning (ISL) and its relation with demographic, clinical, and working memory (WM) capacity using an eye-tracked variant of the standard serial reaction time (RT; SRT) task. Besides RT, this ocular SRT (O-SRT) task enables generation of correct anticipations (CA) and stucks, reflecting other critical aspects of ISL. Method: ISL was tested in 26 individuals with TBI and 28 healthy controls using the O-SRT task. Mixed analyses of variance were conducted to analyze RT and CA in three phases: learning, interference, and recovery from interference. The average number of stucks was compared with an independent-samples t test. Finally, Pearson correlation analyses of ISL with demographic, clinical, and WM capacity measures were performed. Results: Based on RT, ISL was impaired in the TBI group. However, CA demonstrated improved learning, but with deficits in the interference and recovery from interference phases. Stucks were more frequent in the TBI group, which affected RT and CA measures. Neither demographic nor clinical factors were associated with ISL. Verbal, but not spatial, WM capacity was impaired in the TBI group, and spatial WM capacity positively correlated with ISL in controls only. Conclusion: We suggest that the high TBI group stuck rate can be attributed to lack of initiative and/or conservative response bias associated with TBI, and view it as a main cause leading to deficits in ISL. Unlike controls, the TBI group could not muster their relatively preserved spatial WM capacity to support their ISL performance.
