Comparison of Blood Culture Parameters between 2 and 10 mL Aerobic Bottles from Patients with Sepsis

open access: yesAnnals of Clinical Microbiology, 2021
Background: Blood volume is the most important parameter for an optimal blood culture; however, the effect of blood volume on blood culture is not clearly understood from patients with sepsis. Methods: Blood cultures were obtained from 1,049 patients (≥

Educational Intervention to Improve Blood Culture Indicators in a Secondary-Care Hospital

open access: yesAnnals of Clinical Microbiology, 2021
배경: 혈액배양은 패혈증을 진단하는데 필수적인 검사이다. 혈액배양 시 충분한 양의 혈액 채취가 중요하며, 질 향상을 위해서는 주기적으로 채혈량 모니터링과 피드백이 필요하다.방법: 2차 의료기관에서 혈액배양 시 고려해야 할 점에 대해서 채혈전담자를 대상으로 교육을 시행하였다.

Postural Hyperventilation as a Cause of Postural Tachycardia Syndrome: Increased Systemic Vascular Resistance and Decreased Cardiac Output When Upright in All Postural Tachycardia Syndrome Variants

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Postural tachycardia syndrome (POTS) is a heterogeneous condition. We stratified patients previously evaluated for POTS on the basis of supine resting cardiac output (CO) or with the complaint of platypnea or “shortness of breath” during ...
