Due to its anatomical complexity, a tracheal bronchus has important clinical implications for one-lung ventilation (OLV). We present a case of successful OLV in a patient with a high a type I (i.e., high take-off) tracheal bronchus. This anomaly presented unusual fibreoptic bronchoscopic (FOB) views that were difficult to discern from the normal carinal bifurcation. ⋯ Careful preoperative assessment of tracheobronchial anatomy is imperative in order to choose an appropriate method of OLV and prevent potential complications. In a type I tracheal bronchus with a narrowed distal trachea, a bronchial blocker may have advantages over the conventional DLT in achieving OLV.

Lumbar plexus (LP) block is a common and useful regional anesthesia technique. Surface landmarks used to identify the LP in patients with healthy spines have been previously described, with the distance from the spinous process (SP) to the skin overlying the LP being approximately two-thirds the distance from the SP to the posterior superior iliac spine (PSIS) (SP-LP:SP-PSIS ratio). In scoliotic patients, rotation of the central neuraxis may make these surface landmarks unreliable, possibly leading to an increased block failure rate and an increased incidence of complications. The objective of the present study was to describe these surface landmarks of the LP in patients with scoliosis. ⋯ In patients with scoliotic disease of the spine, there is wide variability in the bony surface landmarks. The location of the LP is generally more medial than expected when compared with both modified and traditional landmarks. A review of the imaging studies and the pre-procedural ultrasound assessment of the anatomy should be considered prior to needle puncture.

Randomized Controlled Trial Multicenter Study
Intraoperative awareness risk, anesthetic sensitivity, and anesthetic management for patients with natural red hair: a matched cohort study.
Red-haired patients show no greater risk of intraoperative awareness than other phenotypes.

Multicenter Study Comparative Study
Combined general and neuraxial anesthesia versus general anesthesia: a population-based cohort study.
To determine whether combining spinal or epidural anesthesia with general anesthesia (combined anesthesia) reduces major medical complications of elective surgery compared with general anesthesia alone. ⋯ The addition of spinal or epidural anesthesia to general anesthesia was not associated with a reduced risk of major medical complications among 21 different elective procedures when compared with general anesthesia alone.
