Randomized Controlled Trial Comparative Study
Effect of tranexamic acid on reducing postoperative blood loss in combined hypotensive epidural anesthesia and general anesthesia for total hip replacement.
To determine whether the use of tranexamic acid in the setting of hypotension induced by hypotensive epidural anesthesia (HEA) has any additional beneficial effects in reducing perioperative blood loss and transfusion requirements in total hip replacement. ⋯ Administration of tranexamic acid combined with hypotensive epidural anesthesia reduced postoperative and total accumulative blood loss and transfusion requirements more than did hypotensive epidural anesthesia alone.

Case Reports
Difficulty in placement of a left-sided double-lumen tube due to aberrant tracheobronchial anatomy.
A rare case of a tracheal bronchus coexisting with a left-shifted carina and an acute angle of left main bronchus is presented. A 66 year old man with a history of colon cancer was scheduled for right thoracoscopic pericardial window due to recurrent pericardial effusion. After induction of anesthesia, the trachea was intubated using a 39-French, left-sided double lumen tube (DLT); the DLT was positioned with fiberoptic bronchoscopic guidance. ⋯ While repositioning the DLT, we found an aberrant tracheal bronchus. Although multiple attempts were made to adjust the DLT so as to achieve lung isolation, we could not place the DLT in the appropriate position due to abnormal and distorted anatomy. Lung isolation was unsuccessful; both lungs were carefully ventilated with small tidal volumes.

Training to be an historian of anesthesia: options at universities in the United States.
To determine whether a lack of training opportunities explains the finding that few anesthesia historians have obtained formal training in history. ⋯ Graduate training in history of anesthesia is currently unavailable, and specific opportunities in history of medicine are quite limited. Individuals wishing to obtain formal training in history of anesthesia need to enroll in a history of science or history of medicine program, and choose a research topic in history of anesthesia.

Randomized Controlled Trial
Effects of the menstrual cycle on injection pain due to rocuronium.
To investigate the effect of the menstrual cycle on rocuronium injection pain. ⋯ Menstrual cycle phases affect the severity of rocuronium injection pain. Women exhibit greater pain sensitivity from rocuronium injection in the luteal phase than the follicular phase.
