Randomized Controlled TrialComparison of Antinociceptive Properties Between Sevoflurane and Desflurane Using Pupillary Dilation Reflex Under Equivalent Minimum Alveolar Concentration: A Randomized Controlled Trial.
The pupillary dilation reflex (PDR), the change in pupil size after a nociceptive stimulus, has been used to assess antinociception during anesthesia. The aim of this study was to compare the antinociceptive properties of sevoflurane and desflurane by measuring the PDR amplitude. ⋯ The amount of change in the PDR amplitude, MAP, and HR after SNT was not different between sevoflurane and desflurane anesthesia. This result might suggest that sevoflurane and desflurane may not have different antinociceptive properties at equivalent MAC.

Relationship Between Glottic View and Intubation Force During Macintosh and Airtraq Laryngoscopy and Intubation.
Because intubation-mediated cervical spine and spinal cord injury are likely determined by intubation force magnitude, understanding the determinants of intubation force magnitude is clinically relevant. With direct (Macintosh) laryngoscopy, when glottic view is less favorable, anesthesiologists apply greater force. We hypothesized that, when compared with direct (Macintosh) laryngoscopy, intubation force with an optical indirect laryngoscope (Airtraq) would be less dependent on glottic visualization. ⋯ Previously, we reported that intubation force with the Airtraq was less in magnitude compared with the Macintosh. Our current study adds that intubation force also is less dependent on glottic view with Airtraq compared with the Macintosh.

The provision of health services has been transforming from a largely top-down, paternalistic model into a construct in which patients play a substantive role in decision making over their care. Two articles in this month's issue of Anesthesia & Analgesia and an accompanying editorial address the growing momentum behind transparency in health care. Firstly, Quinonez et al consider the increasing expectation of family presence during surgical procedures and resuscitation of loved ones. ⋯ In conjunction with the increased desire for physical presence of loved ones during clinical procedures, so too is there a demand for complete access to all medical records, including even the arcane hieroglyphics of an anesthesia record as detailed by Ramaswamy et al. As federal law now mandates such access, questions naturally arise as to their utility and medicolegal implications. The reader is strongly encouraged to review the concepts elaborated in these articles for in depth appreciation of their considerations.
