Usefulness of a stool to stabilize dental chairs for external chest compression

Abstract Background: Cardiopulmonary resuscitation (CPR) requires immediate start of external chest compression (ECC) and cardioversion 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 ECC. We previously developed a procedure to stabilize a dental chair by using a stool. 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. ECC 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 ECC were compared between with and without a stool, and recorded by a camcorder. Results: In all 8 dental chairs, the method by using a stool significantly (p < 0.001) reduced the vertical displacements of the backrest by ECC. The reduction ratio varies varied between nearly 39 and 85%, and the overall mean was 62 ± 11%although it was different by chairs. Conclusions: Our procedure to stabilize dental chairs by using a stool reduced the displacement of a backrest against ECC in all chairs. Clinical relevance: Effective ECC could be performed in dental chairs by using a stool when sudden cardiac arrest occurs during dental surgery.

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).

Erc Guidelines

Background; BLS algorithms for health care providers or experience personnel recommended by AHA, European Resuscitation Council (ERC), and Japanese Resuscitation Council (JPN) differ with respect to the sequence of assessment and procedures. The differences may affect accuracy to diagnose cardiac arrest and quickness to start chest compression. We compared BLS algorithms recommended by these organizations with respect to accuracy of respiratory/circulatory assessment, and quickness to start chest compression using a computed manikin model. Methods; Thirty three subjects (16 physicians and 17 medical students) were enrolled. The Sim-Man (Laerdal) was used to develop 2 scenarios (no pulse/no breathing, with pulse 60/min and breathing 10/min). The three algorithms and 2 scenarios were randomly assigned to the subject, and the accuracy to diagnose cardiac arrest and the time from confirmation of loss of consciousness to starting chest compression were evaluated. Results; The rates of incorrect assessment of respiratory/circulatory status were AHA;9.8% (13 out of 132), ERC;9.1%(12 out of 132) and JPN;6.8%(9 out of 132)(n.s. among algorithms). When the results were analyzed with respect to clinical experiences of the subjects, i.e. physicians vs. medical students, significant differences were found between the groups: AHA;17.2% (11 out of 64), ERC;15.6% (10 out of 64), JPN;12.5% (8 out of 64) in students, whereas AHA;2.9% (2 out of 68), ERC;2.9% (2 out of 68), JPN;1.5% (1 out of 68) in physicians* (* p<0.05 vs. students). The time to starting chest compression were AHA;27.8±5.1 sec, ERC;18.6±3.2** sec, JPN;23.7±4.2 sec (**p<0.05 vs. AHA and JPN), and no significant differences were found between physicians and students. Conclusions; No differences were found in accuracy of respiratory and circulatory assessment among the algorithms, although it may be influenced by clinical experiences of evaluators. The BLS algorithm starting CPR from chest compression such as ERC guidelines may reduce the time of no-flow status in cardiac arrest.

Abstract During cardiopulmonary resuscitation (CPR), almost commercially dental chairs lack sufficient stability to perform effective manual chest compression (MCC). In our previous study, our technique that stabilizing stool can significantly reduce vertical displacement in a dental chair’s backrest. This study demonstrates that the efficacy of different methods for stabilizing 3 types of dental chair with a flat or a severely curved backrest exterior for effective MCC. Vertical displacement of the dental chair’s backrest was recorded. The data was captured with three different stool positions (no stool, under MCC, under shoulders). Reduction ratios were calculated to evaluate the effectiveness of the stool positions. In all types of dental chair, the technique significantly reduced the vertical displacements of the backrest. The reduction ratio varied nearly 40% under the area for MCC and 65% under the shoulder with a severely curved backrest exterior. With a flat shape of dental chair, these ratios were around 90% versus without a stool. The technique is a firm support and reduce the displacement of any type of dental chair’s backrest for effective MCC.

Life Threatening

Abstract Background: Out-of-hospital cardiac arrest (OHCA) is a life-threatening condition with an overall survival rate that generally does not exceed 10%. Several factors play essential roles in increasing survival among patients experiencing cardiac arrest outside the hospital. Previous studies have reported that implementing a dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) program increases bystander CPR, quality of chest compressions, and patient survival. This study aimed to assess the effectiveness of a DA-CPR program developed by the Thailand National Institute for Emergency Medicine (NIEMS). Methods: This was an experimental study using a manikin model. The participants comprised both health care providers and non-health care providers aged 18 to 60 years. They were randomly assigned to either the DA-CPR group or the uninstructed CPR (U-CPR) group and performed chest compressions on a manikin model for two minutes. The sequentially numbered, opaque, sealed envelope method was used for randomization in blocks of four with a ratio of 1:1. Results: There were 100 participants in this study (49 in the DA-CPR group and 51 in the U-CPR group). Time to initiate chest compressions was statistically significantly longer in the DA-CPR group than in the U-CPR group (85.82 [SD = 32.54] seconds versus 23.94 [SD = 16.70] seconds; P <.001). However, the CPR instruction did not translate into better performance or quality of chest compressions for the overall sample or for health care or non-health care providers. Conclusion: Those in the CPR-trained group applied chest compressions (initiated CPR) more quickly than those who initiated CPR based upon dispatch-based CPR instructions.

Scientific Statement

Abstract Background The COVID-19 pandemic poses a major burden to the healthcare system in Egypt, and in the face of a highly infective disease which can prove fatal, healthcare systems need to change their management protocols to meet these new challenges. Main body This scientific statement, developed by the cardiology department at Cairo University, emphasized 6 different aspects that are intended to guide healthcare providers during cardiopulmonary resuscitation (CPR) in the era of the COVID-19 pandemic. It highlighted the importance of dealing with all cardiac arrest victims, during the pandemic, as potential COVID-19 cases, and the use of appropriate personal protective equipment (PPE) by health care providers during the procedure. It also stated that the CPR procedure should be done in a separate room with the door closed and that the number of providers present during the procedure should be limited to only those who are essential for patient resuscitation. It also stressed that family members and accompanying personnel of patients with possible COVID-19 should not be in the vicinity of CPR site. The statement also pointed out that CPR procedure should be done in the standard manner with precautions to minimize spread of infection to the staff and accompanying people. Early intubation was prioritized, and the use of rapid sequence intubation with appropriate PPE was recommended. For delivery of CPR for the prone ventilated patient, delivery of chest compressions by pressing the patient’s back, while a team prepares to turn the patient supine, was recommended. During intra-hospital transport, it was emphasized that the receiving intensive care unit (ICU) should be notified about the possibility of the patient being COVID-19 positive, so that appropriate infection control precautions are taken. Conclusion Cardiopulmonary resuscitation of cardiac arrest patients in the COVID-19 era poses a significant challenge, and all health care providers should deal with any cardiac arrest victim presenting to the emergency department as potential COVID-19 suspects and should use the appropriate PPE.
