[Judgement on students' exercise for resuscitation using a manikin for CPCR exercise (1st report)].

Abstract

We performed the training for resuscitation using dental students and used a manikin for CPCR Exercise before and after the training to investigate the result obtained. The results were as follows. 1. Although cases in which too much or too little ventilation in amount was judged showed no significant changes before and after the training, those judged too much in ventilation amounted to approx. 1/5 and those judged too little were approx. 1/2 of the total subjects. This suggests that it is preferable to instruct the students to maintain sufficient ventilation when allowing them to exercise artificial breathing of CPCR. But the instruction is somewhat difficult to take because inhibition of gastric distention should be taken into account. 2. Although no changes were shown before and after the training by cases judged too deep in the depth of thoracic oppression, the number of those cases amounted to approx. 4/5 of the total subjects. Cases judged too shallow in depth of thoracic oppression, on the other hand, were significantly decreased from approx. 4/5 before training to approx. 2/3 after training, suggesting that improvement of the shallow oppression initially made is easy rather than to improve the oppression unduly deepened. Accordingly, it appears effective for students to avoid undue oppression when they are trained. 3. Thoracic oppression at a correct position was increased significantly to approx. 1/5 of the total cases, although most of the subjects were in error to choose a correct position for thoracic oppression before training.(ABSTRACT TRUNCATED AT 250 WORDS)
