BACKGROUND: The outcomes of patients with cardiac arrest induced by non-traumatic hemorrhagic cardiac tamponade are poor. PURPOSE: We retrospectively investigated the significance of medical intervention with pericardiocentesis and/or pericardiotomy for non-traumatic hemorrhagic cardiac tamponade. METHODS: From January 2013 to April 2021, we retrospectively reviewed the medical charts of all patients with cardiac arrest in a prehospital setting or emergency room due to cardiac tamponade confirmed by an ultrasound examination with or without an invasive procedure (pericardiocentesis and/or pericardiotomy) and computed tomography findings, including those obtained at autopsy imaging. The subjects were divided into two groups: the Intervention (+) group, which included subjects who underwent pericardiocentesis or pericardiotomy, and the Intervention (-) group, which included subjects who did not undergo pericardiocentesis or pericardiotomy. Variables were then compared between the two groups. RESULTS: There were 68 patients with non-traumatic cardiac tamponade. All three survival cases had witnessed collapse, and the initial rhythm was pulseless electrical activity (PEA).There were no statistically significant differences in the sex, age, means of transportation, bystander chest compression, electric shock, or adrenalineor FDP levels between the two groups.However, the number with witnessed collapse, PEA, rupture of the heart;the ratio of obtaining return of spontaneous circulation; and the survival ratio were significantly greater in the Intervention (+) group than in the Intervention (-) group. CONCLUSION: Based on the results of preliminary study, we hypothesized that invasive medical intervention for patients with cardiac arrest induced by non-traumatic hemorrhagic cardiac tamponade might be useful for obtaining return of spontaneous circulation and a survival outcome, especially for patients with witnessed collapse with PEA as the initial rhythm.

OBJECTIVE: To determine whether anaphylactic patients treated by the doctor helicopter (DH) staff and transported from the scene obtained a favorable outcome by analyzing changes in vital signs and clinical manifestation before and after treatment during flight. METHODS: We retrospectively investigated all of the patients with anaphylaxis who were transported by the DH between March 2004 and February 2017. RESULTS: A total of 68 cases were enrolled in the present study. The average age was 48 years old, and most were men. The most frequent cause of anaphylaxis was a beesting or wasp sting followed by a food allergy. Adrenaline injections were executed at the scene for 48 cases. The condition of 64 (94%) subjects improved or totally subsided (n = 25, 37%) after arriving at the hospital. The Glasgow Coma Scale, peripheral capillary oxygen saturation, and systolic blood pressure after transportation to a hospital were higher than before transportation. All subjects who were treated by the DH staff obtained a survival outcome without sequelae. CONCLUSION: The vital signs and clinical conditions of the patients who were treated by the DH staff when they were in an anaphylactic state at the scene showed improvement when they arrived at the hospital.

OBJECTIVE: The purpose of this study was to investigate the safety of evacuating patients using a physician-staffed helicopter (Dr. Heli). METHODS: We retrospectively investigated all of the patients with acute coronary syndrome (ACS) who were transported by a Dr. Heli between April 2004 and March 2016. The scene group included subjects evacuated from the scene by the Dr. Heli. The interhospital group included subjects transported to a nearby medical facility by a ground ambulance and then transported to our hospital by a Dr. Heli. RESULTS: The scene and interhospital groups included 170 subjects and 592 subjects, respectively. There were no significant differences between the 2 groups with regard to sex and survival ratios. However, the patients in the scene group were significantly younger than those in the interhospital group. The ratio of prehospital cardiopulmonary arrest in the scene group was significantly higher than in the interhospital group. After excluding subjects who were over 80 years of age, there were no significant differences between the 2 groups with regard to age. However, the same tendencies remained. CONCLUSION: This result indirectly suggests the safety of using the Dr. Heli to evacuate ACS patients from the scene.
