Randomized Controlled Trial
Effect of bilateral scalp nerve blocks on postoperative pain and discharge times in patients undergoing supratentorial craniotomy and general anesthesia: a randomized-controlled trial.
Post-craniotomy pain is a common clinical issue and its optimal management remains incompletely studied. Utilization of a regional scalp block has the potential advantage of reducing perioperative pain and opioid consumption, thereby facilitating optimal postoperative neurologic assessment. The purpose of this study was to assess the efficacy of regional scalp block on post-craniotomy pain and opioid consumption. ⋯ These data show that bilateral scalp blocks using bupivacaine with epinephrine did not reduce mean postoperative VAS score or overall opioid consumption at 24 hr nor the time-to-discharge from the postanesthesia care unit or from hospital.

Multicenter Study Observational Study
Using bioimpedance analysis to assess intensive care unit patients with sepsis in the post-resuscitation period: a prospective multicentre observational study.
Clinicians lack well-validated, non-invasive, objective tools to guide volume management in the post-resuscitative period. Bioimpedance analysis (BIA) represents a novel method for guiding fluid management. We studied the relationship of BIA vector length (VL), an indicator of volume status, to the need for mechanical ventilation in patients with sepsis. ⋯ An increase in VL over time is associated with a decrease in probability of requiring invasive mechanical ventilation. Vector length correlates with other commonly used volume assessment methods in post-resuscitation patients with sepsis.

Isotonic 0.9% sodium chloride (normal saline; NS) solution use is common, but its high chloride content has been shown to contribute to acid-base disturbances and acute kidney injury (AKI). As kidney transplant recipients are at high risk of postoperative AKI and renal replacement therapy, we aimed to evaluate the impact of perioperative NS administration on graft function after kidney transplantation. ⋯ Perioperative NS infusion volume was associated with DGF in deceased-donor kidney transplant recipients. Conversely, postoperative hyperchloremia and hyperchloremic acidosis were not associated with an increased risk of DGF, suggesting other mechanisms than a chloride effect.

Despite an increase in the proportion of women entering the field of anesthesiology, women remain underrepresented in academic and leadership positions. Speaking at national and international conferences is an important component of academic visibility and promotion. To date, the gender representation of speakers at the Canadian Anesthesiologists' Society (CAS) annual meeting has not been examined. ⋯ The representation of women speakers at the CAS annual meeting was similar to the representation of women in the anesthesiology workforce in Canada over the study period. Gender representation varied widely by subspecialty symposia, subject area, and women were absent from nearly half of all symposia at the CAS annual meetings, which are potential areas of future investigation and intervention.
