Estimation of catheter insertion depth during ultrasound-guided subclavian venous catheterization.
Several methods have been used to predict the optimal depth of central venous catheter (CVC) tip position when using the anatomical landmark technique. In the present study, we devised a simple formula to predict CVC depth using ultrasound images and chest X-ray (CXR) in patients undergoing ultrasound-guided subclavian venous catheterization. ⋯ The appropriate length of a CVC inserted through the subclavian vein can be estimated by a formula using ultrasound images and CXR.

Sarpogrelate hydrochloride, a serotonin 5HT2A receptor antagonist, ameliorates the development of chronic hypoxic pulmonary hypertension in rats.
The purpose of the present study was to determine if sarpogrelate hydrochloride (SPG), a serotonin 5HT2A receptor antagonist, prevented the development of chronic hypoxia-induced pulmonary hypertension (PH) and hypertensive pulmonary vascular remodeling. ⋯ The administration of SPG ameliorated the development of chronic hypoxic PH and hypertensive pulmonary vascular changes.

Influence of clinical experience of the Macintosh laryngoscope on performance with the Pentax-AWS Airway Scope(®), a rigid video-laryngoscope, by paramedics in Japan.
We sought to establish the clinical utility of the Pentax-AWS Airway Scope(®) (AWS) when used by paramedics to intubate the trachea, and to evaluate whether their performance was influenced by previous clinical experience with the Macintosh laryngoscope (ML). ⋯ We found that paramedics could achieve a high tracheal intubation success rate using the AWS independent of previous airway management experience. Better intubation performance with the AWS was observed in paramedics without clinical experience with the ML.

Case ReportsDrug fever caused by propofol in the intensive care unit.
Few studies have reported that fever is caused by intravenous sedative drugs even though these agents are widely used. We present a case of propofol-induced drug fever. A 57-year-old woman underwent hepatic segmentectomy. ⋯ On day 5 after surgery, propofol infusion was discontinued and the patient was extubated. Her temperature of 37.7 °C at the discontinuation of propofol infusion, and rapidly decreased to 36.1 °C in the following 3 h. Propofol-induced drug fever must be considered in cases of fever of unknown origin when patients receive propofol and appear inappropriately well for the degree of fever that they have.
