Review Meta Analysis
Perception of auditory stimuli during general anesthesia and its effects on patient outcomes: a systematic review and meta-analysis.
Interest in implicit memory formation and unconscious auditory stimulus perception during general anesthesia has resurfaced as perioperative music has been reported to produce beneficial effects. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating explicit and implicit memory formation during general anesthesia and its effects on postoperative patient outcomes and recovery. ⋯ The results of this systematic review and meta-analysis show that intraoperative auditory stimuli can be perceived and processed during clinically adequate, general anesthesia irrespective of surgical procedure severity, leading to implicit memory formation without explicit awareness. Intraoperative music can exert significant beneficial effects on postoperative pain and opioid requirements. Whether the employed intraoperative anesthesia regimen is of influence is not yet clear.

Intravascular fluids are a necessary and universal component of cardiac surgical patient care. Both crystalloids and colloids are used to maintain or restore circulating plasma volume and ensure adequate organ perfusion. In Canada, human albumin solution (5% or 25% concentration) is a colloid commonly used for this purpose. In this narrative review, we discuss albumin supply in Canada, explore the perceived advantages of albumin, and describe the clinical literature supporting and refuting albumin use over other fluids in the adult cardiac surgical population. ⋯ In cardiac surgical patients, albumin is widely utilized despite a lack of high- quality evidence supporting its efficacy or safety. A well-designed randomized controlled trial is needed to clarify the role of albumin in cardiac surgical patients.

The Apfel simplified risk score, developed in 1999, is the most widely used tool for risk stratification of postoperative nausea and vomiting (PONV). It includes four risk factors: female sex, non-smoking status, history of PONV or motion sickness, and use of postoperative opioids. Nevertheless, there is considerable heterogeneity in the definition and application of these risk factors in PONV research. Our aim was to determine how these risk factors are implemented in studies employing the Apfel score. ⋯ Significant variation exists in how the Apfel risk factors are defined and applied in PONV research, particularly with respect to postoperative opioid use. More guidance in the application of this tool may optimize risk estimation and PONV prophylaxis, and potentially improve research quality.

Review
[The impact of unilateral diaphragmatic paralysis on sleep-disordered breathing: a scoping review].
Unilateral diaphragm paralysis (UDP) may potentially worsen sleep-disordered breathing (SDB). Unilateral diaphragm paralysis has been associated with proximal brachial plexus blockade, such as interscalene and supraclavicular block. The impact of UDP in patients with SDB is not known in this context. The objectives of this scoping review were to explore the associations between UDP and worsening SDB severity, oxygenation, and pulmonary function. ⋯ We observed an association between UDP and increasing SDB severity, particularly during REM sleep and while sleeping in the supine position. Although we identified weaknesses in study design and lack of perioperative data, anesthesiologists should be aware of this association when considering proximal brachial plexus blockade in patients with SDB.
