Guidelines on human factors in critical situations 2023.

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.

Training novice in ultrasound-guided venipuncture: A randomized controlled trial comparing out-of-plane needle-guided versus free-hand ultrasound techniques on a simulator.

BACKGROUND: Peripheral intravenous access is a common medical procedure, however, it can be difficult to perform in some patients. Success rates have proved greater with ultrasound guidance. Peripheral intravenous access using ultrasound requires specific training, especially for new ultrasound users. To overcome these difficulties, guidance devices on ultrasound probes are able to control the angle of penetration into tissues. We hypothesized that, and particularly for new ultrasound users, the use of a needle guide (NG) paired with the out-of-plane approach would facilitate puncture of a simulation model of vessel more effectively than similar free hand (FH) techniques. METHODS: A prospective controlled randomized study was conducted of new ultrasound users using a guide wire introducer needle on gelatine phantom. After a 30-min lecture, one group performed the FH technique and the other group performed the NG technique both in an out-of-plane approach. The main criterion was the number of attempts before success of catheterization of this model of vessel. RESULTS: Thirty-four nurse anesthetist students participated in the study. The number of attempts before success using the NG technique was significantly lower: 3.7 (±0.9) in the NG group versus 6.7 (±3.3) in the FH group (p = 0.01). In the NG group, 100% of the participants achieved success after the sixth attempt. In the FH group, only 81.25% (n = 13/16) reached success. CONCLUSION: NG technique has been proved to have a steeper learning curve compared with the FH technique. A study on a learning curve in clinical practice is needed to confirm these results.
