RESUMO
Background: Workplace wellbeing programs can be beneficial but range widely in approach. A group coaching model offers numerous benefits. Objective: To evaluate feasibility of group coaching for employees during COVID-19. Methods: Employees (n = 29) at a university and university hospital underwent a 12-week group coaching program. Measurements of feasibility -- including enrollment, attendance at sessions goal attainment and satisfaction -- and exploratory outcomes including perceived physical and mental health and stress were administered at beginning, middle, and end of the program, plus 2 follow-ups. Results: Twenty-six of the 29 program enrollees (96% women; 65% university employees) opted to complete surveys at 1 or more time points, and 9 individuals completed surveys at all 5 time points. Median attendance was 9 sessions. Participants opted to focus on movement, nutrition and mind/body goals and all participants reported making progress toward their goal during the program. Exploratory wellness outcomes showed meaningful improvements in perceived physical and mental health and reduced stress during the program, with return to near baseline 12 weeks after program completion. Perceptions of workplace wellness culture varied by employer. Conclusion: Despite pandemic-related disruptions to life, work, and health, online group coaching is feasible and acceptable to participants. The program should be replicated to evaluate whether the improvements in exploratory wellness outcomes observed during the program are statistically significant. The apparent return to baseline levels by 24 weeks suggests that post-program maintenance support may be helpful.
RESUMO
CONTEXT: Malignant hyperthermia may follow exposure to trace quantities of inhalational anaesthetics. In susceptible patients, the complete avoidance of these triggers is advised when possible; however, failing this, it is essential to washout or purge the anaesthesia machine of residual inhalational anaesthetics. OBJECTIVE: This study examined the washout profile of sevoflurane from the Drager Fabius CE and the Drager Zeus machines. DESIGN: The washout profile of sevoflurane was measured from the Fabius CE and Zeus anaesthesia machines following a standard period of exposure. The disposable tubing, CO2 absorber and other components of each machine were then replaced to examine their impact on the retention of sevoflurane. The effect of autoclaving the ventilator diaphragm and non-disposable ventilator tube or substituting for a new diaphragm and ventilation tube were examined in later parts of this study. SETTING: University teaching hospital. MAIN OUTCOME MEASURE: Time taken to reach 5 parts per million of sevoflurane when machines underwent standard washout with fresh gas flush. RESULTS: The concentration of sevoflurane reached 5 parts per million in the Fabius CE machines after an mean (SD) of 140 min (46) at a fresh gas flow (FGF) of 10 l min(-1). The time taken for sevoflurane to reach 5 parts per million was significantly reduced when the ventilator diaphragm and non-disposable tube were replaced with either new or autoclaved components [14 or 22 min, respectively (P = 0.017, P = 0.031)]. The concentration of sevoflurane reached 5 parts per million in the Zeus machines after an mean (SD) of 85 min (6) at a fresh gas flow of 10 l min(-1). When the fresh gas flow was increased to 18 l min(-1) (the maximum allowable), the time to reach 5 parts per million was reduced to 16 min. CONCLUSION: When preparing the Fabius CE for the malignant hyperthermia susceptible patient, remove the vaporiser, replace the disposable tubing, the reservoir bag and the CO2 absorber. Replace the ventilator diaphragm and non-disposable ventilator tube with new or autoclaved components and flush the machine at 10 l min(-1) for at least 36 min. When preparing the Zeus, remove the vaporiser, replace the disposable tubing, the reservoir bag and CO2 absorber and flush at a fresh gas flow of 10 l min(-1) for at least 90 min. In both the Fabius and Zeus, continue at a fresh gas flow of 10 l min(-1) for the duration of the operation.
