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.

Comparative Study
Predicting the appropriate uncuffed endotracheal tube size for children: a radiograph-based formula versus two age-based formulas.
To determine whether a radiograph-based formula using the tracheal diameter from a chest radiograph predicted the appropriate endotracheal tube (ETT) size in children, and to compare these results with those produced using age-based formulas. ⋯ The radiograph-based formula may be useful for predicting the appropriate ETT size in children aged 3 to 6 years.

To identify the risk factors of, and develop a prediction model for, postoperative complications of patients undergoing infrarenal abdominal aortic aneurysm (IAAA) repair. ⋯ A combination of age, COPD, emergency operation, history of cardiac dysfunction and aortic occlusion time has significant impact on postoperative complications after open IAAA repair.

Comparative Study
Analgesia after Cesarean delivery: a retrospective comparison of intrathecal hydromorphone and morphine.
To compare analgesia and opioid-related side effects of intrathecal morphine and intrathecal hydromorphone after elective Cesarean delivery. ⋯ Overall, analgesia and incidence of opioid-related side effects after 0.04 mg of intrathecal hydromorphone did not differ statistically from 0.1 mg of intrathecal morphine.

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.
