Observational StudyEfficacy of height-based formula to predict insertion depth of left-sided double lumen tube: A prospective observational study.
The insertion depth of the left-sided double-lumen tube needs careful positioning and bronchoscopic confirmation. Several formulae based on body height have been used for estimating the optimal insertion depth of a left-sided double-lumen tube. We conducted this prospective study to test the hypothesis that our earlier developed height-based formula (0.25 × body height0.916) could predict the accurate insertion depth of a left-sided double-lumen tube. ⋯ The left-sided double-lumen tube was withdrawn or advanced in 18.2% and 12.1%, respectively, to achieve the optimal insertion depth. We found that our formula provided satisfactory positioning in about 70% of patients and that in the remaining patients, the adjustments required to achieve satisfactory positioning under fibreoptic bronchoscope guidance were minimal. Nevertheless, as it is not possible to predict which patients will have a satisfactory tube position, bronchoscopic confirmation for the final positioning is still required.

Incidences and risk factors for post--dural puncture headache after neuraxial anaesthesia: A national inpatient database study in Japan.
The reported incidence of post--dural puncture headache (PDPH) after neuraxial anaesthesia varies widely, depending on patient and procedural risk factors. Most previous studies have had small sample sizes and focused on obstetric patients. This study aimed to investigate the incidence of PDPH and factors associated with PDPH in non-obstetric and obstetric patients after neuraxial anaesthesia. ⋯ Being in an academic hospital was associated with decreased incidence of PDPH in male patients receiving spinal anaesthesia and female patients receiving spinal or epidural anaesthesia, but increased incidence of PDPH in male patients receiving epidural anaesthesia. Lumbar epidural anaesthesia was associated with increased incidence of PDPH in male patients, but decreased incidence of PDPH in obstetric patients compared with thoracic epidural anaesthesia. The present study identified several potential new risk factors for PDPH, and revealed that the incidence of PDPH in non-obstetric patients after neuraxial anaesthesia was lower than in obstetric patients.

Diagnostic accuracy of viscoelastic point-of-care identification of hypofibrinogenaemia in cardiac surgical patients: A systematic review.
Hypofibrinogenaemia during cardiac surgery may increase blood loss and bleeding complications. Viscoelastic point-of-care tests provide more rapid diagnosis than laboratory measurement, allowing earlier treatment. However, their diagnostic test accuracy for hypofibrinogenaemia has never been reviewed systematically. ⋯ This review demonstrates that there have been few diagnostic test accuracy studies of viscoelastic point-of-care identification of hypofibrinogenaemia in cardiac surgical patients. The studies performed so far report false positive rates of up to 58%, but low false negative rates. Further diagnostic test accuracy studies of viscoelastic point-of-care identification of hypofibrinogenaemia are required to guide their better use during cardiac surgery.
