Usefulness of a stool to stabilize dental chairs for cardiopulmonary resuscitation (CPR)

Abstract

Background Cardiopulmonary resuscitation (CPR) requires immediate start of manual chest compression (MCC) and defibrillation as soon as possible. During dental surgery, CPR could be started in the dental chair considering difficulty to move the patient from the dental chair to the floor. However, all types of dental chairs are not stable for MCC. We previously developed a procedure to stabilize a dental chair by using a stool. EUROPEAN RESUSCITATION COUNCIL (ERC) guideline 2015 adopted our procedure when cardiac arrest during dental surgery. The objective of this study was to verify the efficacy of a stool as a stabilizer in different types of dental chairs. Methods Three health care providers participated in this study, and 8 kinds of dental chairs were examined. MCC were performed on a manikin that was laid on the backrest of a dental chair. A stool was placed under the backrest to stabilize the dental chair. The vertical displacement of the backrest by MCC was recorded by a camcorder and measured by millimeter. Next, the vertical displacement of the backrest by MCC were compared between with and without a stool. Results In all 8 dental chairs, the method by using a stool significantly reduced the vertical displacements of the backrest by during MCC. The reduction ratio (mean [interquartile range]) varied between nearly 27 [20] and 87 [5] %. In the largest stabilization case, the displacement was 3.5 [0.5] mm with a stool versus 26 [5.5] mm without a stool ( p < 0.001). Conclusions Our procedure to stabilize dental chairs by using a stool reduced the displacement of a backrest against MCC in all chairs. Clinical relevance Effective MCC could be performed in dental chairs by using a stool when sudden cardiac arrest occurs during dental surgery.

Comparison of different methods of more effective chest compressions during cardiopulmonary resuscitation (CPR) in the dental chair

“…The study procedure was performed according to a previously established method in which the CPR manikin (Resusci Anne® Torso Basic version 2011; Laerdal Medical AS) was positioned on the reclined dental chair with the upper end of the manikin torso aligned with the top edge of the backrest in Fig. 1 1. , 2.…”

Kreislaufstillstand unter besonderen Umständen

“…Der Zahnarztstuhl soll in eine vollständig horizontale Position gebracht werden. Ein Hocker kann unter der Rückenlehne für zusätzliche Stabilität sorgen [ 472 , 475 , 480 ]. Wenn ein verringerter venöser Rückfluss oder eine Vasodilatation zur Bewusstlosigkeit geführt hat (z.…”
