Abstract:
OBJECTIVE: This study examined the initial partial pressure of carbon dioxide (PCO₂) as a possible indicator of prehospital ventilation and its association with prehospital i-gel in out-of-hospital cardiac arrest (OHCA) patients. METHODS: The demographics and arrest parameters, including i-gel insertion and initial arterial blood gas analysis, of OHCA patients who visited the emergency department were analyzed retrospectively. Linear regression analysis was performed to examine the association between i-gel insertion and the initial PCO₂. RESULTS: A total of 106 patients were investigated. Fifty-six patients had prehospital i-gel insertion and 50 patients did not have a prehospital advanced airway. The initial PCO₂ was higher in the i-gel group than the no advanced airway group (105.2 mmHg [77.5–134.9] vs. 87.5 mmHg [56.8–115.3], P=0.03). Prehospital i-gel insertion was associated with a higher initial PCO₂ level (βcoefficient, 20.3; 95% confidence interval, 2.6–37.9; P=0.03). CONCLUSION: Prehospital insertion of i-gel was associated with higher initial PCO₂ values in OHCA patients compared to no advanced airway.
