Photoplethysmography and Heart Rate Variability for the Diagnosis of Preeclampsia.
The goal of this study was to determine a set of timing, shape, and statistical features available through noninvasive monitoring of maternal electrocardiogram and photoplethysmography that identifies preeclamptic patients. ⋯ Vascular parameters, as assessed noninvasively by photoplethysmography and heart rate variability, may have a role in screening women suspected of having preeclampsia, particularly in areas with limited resources.

Observational StudyPerioperative Steroid Use for Tonsillectomy and Its Association With Reoperation for Posttonsillectomy Hemorrhage: A Retrospective Cohort Study.
Steroids reduce postoperative complications after tonsillectomy such as nausea and vomiting, pain, and delayed recovery. However, steroids may also increase the risk of severe posttonsillectomy bleeding requiring reoperation. ⋯ Steroid use on the day of tonsillectomy was not associated with an increased risk of reoperation for bleeding. Although the wide range of CIs for the ORs could not eliminate the possibility of increased risk, especially in children, the incremental risks of reoperation for steroid use were within an acceptable range for both adults and children. Our results support the safety of perioperative steroid use for tonsillectomy, considering the magnitude of risk of reoperation because of bleeding.

Clinical TrialAxillary Temperature, as Recorded by the iThermonitor WT701, Well Represents Core Temperature in Adults Having Noncardiac Surgery.
Core temperature can be accurately measured from the esophagus or nasopharynx during general anesthesia, but neither site is suitable for neuraxial anesthesia. We therefore determined the precision and accuracy of a novel wireless axillary thermometer, the iThermonitor, to determine its suitability for use during neuraxial anesthesia and in other patients who are not intubated. ⋯ Axillary temperature, as recorded by the iThermonitor WT701, well represents core temperature in adults having noncardiac surgery and thus appears suitable for clinical use.

Macintosh Blade Videolaryngoscopy Combined With Rigid Bonfils Intubation Endoscope Offers a Suitable Alternative for Patients With Difficult Airways.
In the armamentarium of an anesthesiologist, videolaryngoscopy is a valuable addition to secure the airway. However, when the videolaryngoscope (VLS) offers no solution, few options remain. Earlier, we presented an intubation technique combining Macintosh blade VLS and Bonfils intubation endoscope (BIE) for a patient with a history of very difficult intubation. In the present study, we evaluated this technique to establish whether it is a valuable alternative. ⋯ The combined use of a VLS with Macintosh blade and BIE gives the anesthesiologist a valuable alternative intubation option in patients with extremely difficult airways.
