Evaluation of student-to-student local anesthesia administration at the university of barcelona: A cross-sectional study.

INTRODUCTION
To determine changes in anxiety perceived in students during their first experience injecting local anaesthetic and assess the variability in the perception in the teaching/learning experience as surgeons and patients with relation to gender.


MATERIAL AND METHODS
This cross-sectional study was carried out on students enrolled in the Anaesthesia and Resuscitation course at the University of Barcelona. A descriptive and bivariate analysis was carried out using McNemar and Fisher tests. The level of significance was set at a p-value of less than 0.05.


RESULTS
Out of 85 students, a total of 71 responses were obtained. Overall, significant anxiety changes associated with the inferior alveolar nerve block were observed, specifically, before and during (p=0.003), before and after (p<0.001), and during and after (p<0.001) the injection. The calm/relaxed category showed significant differences between before and after (p<0.001) and during and after (p<0.001) the procedure. Opinions and responses from male and females students differed statistically in relation to the injection on each other as preparation for real work situations (p<0.023), recognition of landmarks (p<0.001), determination of the insertion points (p=0.032) and the need for supervision (p=0.043).


CONCLUSIONS
This study showed that the overall, students felt more anxious before being injecting with the anaesthetic and the students learning to give the local anaesthetic to each other is an appropriate learning method. No gender-related differences were observed in the participants.
