RESUMO

Long duration spaceflights to the Moon or Mars are at risk for emergency medical events. Managing a hypoxemic distress and performing an advanced airway procedure such as oro-tracheal intubation may be complicated under weightlessness due to ergonomic constraints. An emergency free-floating intubation would be dangerous because of high failure rates due to stabilization issues that prohibits its implementation in a space environment. Nevertheless, we hypothesized that two configurations could lead to a high first-pass success score for intubation performed by a free-floating operator. In a non-randomized, controlled, cross-over simulation study during a parabolic flight campaign, we evaluated and compared the intubation performance of free-floating trained operators, using either a conventional direct laryngoscope in an ice-pick position or an indirect laryngoscopy with a video-laryngoscope in a classic position at the head of a high-fidelity simulation manikin, in weightlessness and in normogravity. Neither of the two tested conditions reached the minimal terrestrial ILCOR recommendations (95% first-pass success) and therefore could not be recommended for general implementation under weightlessness conditions. Free-floating video laryngoscopy at the head of the manikin had a significant better success score than conventional direct laryngoscopy in an ice-pick position. Our results, combined with the preexisting literature, emphasis the difficulties of performing oro-tracheal intubation, even for experts using modern airway devices, under postural instability in weightlessness. ClinicalTrials registration number NCT05303948.

RESUMO

The recent health crisis has increased the workload and the stress levels of healthcare professionals around the world. Such stressful working environments are conducive to an increased incidence of medical errors. Implementing education and training specifically focused on human and organizational factors can promote teamwork and decrease the risk of error. Such techniques have been extensively deployed, most notably in commercial aviation. Numerous tools have been developed to reduce the risk of error associated with routine tasks, forgetting a task and handling alarm situations during commercial flights. Many of these tools can be transferred to the healthcare sector. After a brief recap about the importance of the working environment, this narrative review aims to highlight several specific tools used in commercial aviation that can be readily transferred to the operating theatre.

RESUMO

OBJECTIVE: To provide guidelines to define the place of human factors in the management of critical situations in anaesthesia and critical care. DESIGN: A committee of nineteen experts from the SFAR and GFHS learned societies was set up. A policy of declaration of links of interest was applied and respected throughout the guideline-producing process. Likewise, the committee did not benefit from any funding from a company marketing a health product (drug or medical device). The committee followed the GRADE® method (Grading of Recommendations Assessment, Development and Evaluation) to assess the quality of the evidence on which the recommendations were based. METHODS: We aimed to formulate recommendations according to the GRADE® methodology for four different fields: 1/ communication, 2/ organisation, 3/ working environment and 4/ training. Each question was formulated according to the PICO format (Patients, Intervention, Comparison, Outcome). The literature review and recommendations were formulated according to the GRADE® methodology. RESULTS: The experts' synthesis work and application of the GRADE® method resulted in 21 recommendations. Since the GRADE® method could not be applied in its entirety to all the questions, the guidelines used the SFAR "Recommendations for Professional Practice" A means of secured communication (RPP) format and the recommendations were formulated as expert opinions. CONCLUSION: Based on strong agreement between experts, we were able to produce 21 recommendations to guide human factors in critical situations.

RESUMO

BACKGROUND: Miscommunication is a leading cause of preventable incidents in healthcare. A number of checklists have been created in an attempt to improve patient outcomes with only a small impact. However, the 2009 WHO Surgical Safety Checklist demonstrated benefits in terms of reduced morbidity and mortality. Our aim was to determine whether use of a Postanaesthesia Team Handover (PATH) checklist would reduce hypoxaemic events in the postanaesthesia care unit (PACU). METHODS: This single-centre, prospective, pre-/post-implementation study was conducted between February 2019 and July 2020 in the PACU of Versailles Private Hospital, Paris, France. Pre-PATH implementation data were collected for 294 consecutive adult patients (≥18 yr old) admitted to the PACU and post-PATH implementation data were collected for 293 consecutive patients. The primary outcome was the rate of hypoxaemic events post-surgery during PACU stay. RESULTS: The rates of hypoxaemic events were 4.1% (11/267 [95% confidence interval {CI}: 2.3-7.2%]) before the PATH checklist was introduced and 0.8% (2/266 [95% CI: 0.2-2.7%]) after. Patients in the PATH group were 5.6 times (odds ratio [OR] [95% CI: 1.3-33.6], P=0.041) less likely to have a hypoxaemic event than those in the control group. The handover process in the PATH checklist group also had significantly less interruptions (38.6% control vs 20.7% PATH; OR=2.5 [95% CI: 1.7-3.7]; P<0.0001). CONCLUSIONS: Implementation of the PATH checklist in adult patients post-surgery was associated with a reduction in the rate of hypoxaemic events in the PACU. These findings support standardisation of the handover process with checklists following anaesthesia and surgery. CLINICAL TRIAL REGISTRATION: NCT03972423.

RESUMO

BACKGROUND: Mental health and well-being is a significant problem for medical students in training. In this study, we aim to estimate the prevalence of anxiety and depressive symptoms, burnout and psychosocial distress in French anaesthesia and intensive care residents. METHODS: A national online observational study used validated questionnaires (Hospital Anxiety and Depression Scale (HADS), Copenhagen Burnout Inventory (CBI), Perceived Stress Scale (PSS) and work-related questions (work-hours per week, night shift per month, safety rest after night shift, average time to start and end work, break time and time for lunch) to assess mental health and well-being of French residents in anaesthesia and intensive care. RESULTS: We obtained 519 answers (22.5% of 2302 students), 55% of respondents working in anaesthesia, 41% in intensive care at the time of study. Residents describe certain symptomatology in anxiety (19.8%) and depressive symptoms (7.8%). PSS identifies a perceived high stress (score > 27) for 55.7% of the subjects. The CBI questionnaire identifies 205 (38.9%) residents undergoing burnout, 80.7% working more than 48 h per week and 39.1% more than 60 h. The duration of work per week (> 50 h), gender (female) and on-going training in intensive care are independent risk factors of psychological suffering. Lifestyle and level of training are not statistically identified risk factors. CONCLUSION: This first online survey of French anaesthesia and intensive care residents reveals a significant frequency of anxiety and depressive symptoms, burnout and a link to potential targets of improvement in work conditions mainly related to the number of work hours per week.

RESUMO

BACKGROUND: The risk of severe medical and surgical events during long-duration spaceflight is significant. In space, many environmental and psychological factors may make tracheal intubation more difficult than on Earth. We hypothesised that, in microgravity, tracheal intubation may be facilitated by the use of a videolaryngoscope compared with direct laryngoscopy. METHODS: In a non-randomised, controlled, cross-over simulation study, we compared intubation performance of novice operators and experts, using either a direct laryngoscope or a videolaryngoscope, in weightlessness and in normogravity. The primary outcome was the success rate of tracheal intubation. Time to intubation and the confidence score into the success of tube placement were also recorded. RESULTS: When novices attempted to intubate the trachea in microgravity, the success rate of tracheal intubation using a videolaryngoscope was significantly higher (20/25 [80%]; 95% confidence interval [CI], 64.3-95.7 vs eight/20 [40%]; 95% CI, 18.5-61.5; P=0.006), and intubation time was shorter, compared with using a direct laryngoscope. In normogravity, the success rate of tracheal intubation by experts was significantly higher than that by novices (16/20 [80%]; 95% CI, 62.5-97.5 vs seven/25 [28%]; 95% CI, 10.4-45.6; P=0.001), but in microgravity, there was no significant difference between the experts and novices (19/20 [95%]; 95% CI, 85.4-100 vs 20/25 [80%]; 95% CI, 64.3-95.7; P=0.113). Higher confidence scores were achieved with videolaryngoscopy compared with direct laryngoscopy by both experts and novices in both microgravity and normogravity. CONCLUSIONS: Videolaryngoscopy was associated with higher intubation success rate and speed, and higher confidence for correct tube placement by novice operators in microgravity, and as such may represent the best technique for advanced airway management during long-duration spaceflight.
