Open-chest versus closed-chest cardiopulmonary resuscitation in blunt trauma: analysis of a nationwide trauma registry

چکیده
BACKGROUND Although open-chest cardiopulmonary resuscitation (OCCPR) is often considered as the last salvage maneuver in critically injured patients, evidence on the effectiveness of OCCPR has been based only on the descriptive studies of limited numbers of cases or expert opinions. This study aimed to compare the effectiveness of OCCPR with that of closed-chest cardiopulmonary resuscitation (CCCPR) in an emergency department (ED). METHODS A nationwide registry-based, retrospective cohort study was conducted. Patients with blunt trauma, undergoing cardiopulmonary resuscitation (CPR) in an ED between 2004 and 2015 were identified and divided into OCCPR and CCCPR groups. Their outcomes (survival to hospital discharge and survival over 24 hours following ED arrival) were compared with propensity score matching analysis and instrumental variable analysis. RESULTS A total of 6510 patients (OCCPR, 2192; CCCPR, 4318) were analyzed. The in-hospital and 24-hour survival rates in OCCPR patients were 1.8% (40/2192) and 5.6% (123/2192), and those in CCCPR patients were 3.6% (156/4318) and 9.6% (416/4318), respectively. In the propensity score-matched subjects, OCCPR patients (n = 1804) had significantly lower odds of survival to hospital discharge (odds ratio (95% CI)) = 0.41 (0.25-0.68)) and of survival over 24 hours following ED arrival (OR (95% CI) = 0.59 (0.45-0.79)) than CCCPR patients (n = 1804). Subgroup analysis revealed that OCCPR was associated with a poorer outcome compared to CCCPR in patients with severe pelvis and lower extremity injury. CONCLUSIONS In this large cohort, OCCPR was associated with reduced in-hospital and 24-hour survival rates in patients with blunt trauma. Further comparisons between OCCPR and CCCPR using additional information, such as time course details in pre-hospital and ED settings, anatomical details regarding region of injury, and neurological outcomes, are necessary.

Comparative Effectiveness of Emergency Resuscitative Thoracotomy versus Closed Chest Compressions among Patients with Critical Blunt Trauma: A Nationwide Cohort Study in Japan.
BACKGROUND Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency departm...
متن کاملLimited evidence to recommend against open chest cardiopulmonary resuscitation in blunt trauma
Main Text We congratulate Endo and co-authors on their retrospective registry-based analysis comparing closed-chest cardiopulmonary resuscitation (CCCPR) and open-chest cardiopulmonary resuscitation (OCCPR) in cardiac arrest patients following blunt trauma [1] and would like to share the following comments. OCCPR is generally deemed futile in blunt trauma patients whenever cardiopulmonary resus...

Background and Objective: Open-chest cardiopulmonary resuscitation (OCCCPR) may be the only method of increasing the survival rate as well as the cardiorespiratory circulation of blunt chest or abdominal trauma patients undergoing cardiac arrest, however, it has always been a difficult challenge for medical staff to carry out on-sight OCCPR because it requires high level of expertise. Unfortuna...
متن کاملConservative management of flail chest after cardiopulmonary resuscitation by continuous negative extrathoracic pressure.
Flail chest after blunt trauma usually requires good pain control and positive pressure support. Continuous negative extrathoracic pressure (CNEP) causes a splinting effect around the anterior chest wall and upper abdomen which increases functional residual capacity and improves lung mechanics. We report an 82-year-old woman with flail chest after cardiopulmonary resuscitation. She underwent me...

Background: Chest X-rays (CXRs) are traditionally performed to determine intra-thoracic injuries in all blunt chest trauma patients in Shahid Bahonar hospital in Kerman. As there are some disadvantages upon CXR and radiation exposure, therefore, this study aimed to evaluate the role of CXR in the diagnosis of intra-thoracic injuries caused by any blunt chest trauma. Me...
