Abstract：Objective To investigate the effect of gastric volume on the recovery of spontaneous circulation(ROSC)during cardiopulmonary resuscitation in patients with out of hospital cardiac arrest(OHCA).Methods The clinical data of 106 OHCA patients admitted to the Resuscitation Room of the Department of Emergency Medicine,Eastern Theater General Hospital of the Chinese People's Liberation Army from July 2021 to January 2023 were retrospectively analyzed.Patients were divided into a gastric distension group(28 cases)and a non gastric distension group(78 cases)based on the median percentage of gastric contents(including gas)in the negative pressure suction tray of the gastric tube after arrival at the hospital(defined as gastric distension if ≥ 75％).Baseline clinical data,ROSC and 30 d survival were compared between the two groups.The relationship between related clinical factors and ROSC,and the relationship between gastric volume and related clinical factors were analyzed.Results There was no significant difference in age,gender distribution,pre-hospital emergency care and pre-hospital time between the two groups(all P＞0.05).There was no significant difference in ROSC rate and 30 d survival rate between gastric distension group and nongastric distension group[28.6％(8/28)vs 25.6％(20/78),7.1％(5/28)vs 3.8％(3/78)](P=0.441,0.993).Multivariate Logistic regression analysis showed that cardiopulmonary resuscitation,airway management and epinephrine management were independent risk factors for death events in OHCA patients(all P＜0.05).Gastric volume was not associated with ROSC outcome(P=0.280).Conclusion Excessive gastric contents do not affect ROSC during cardiopulmonary resuscitation.
