Observational StudyRelationship of abdominal circumference and trunk length with spinal anesthesia level in the term parturient.
We hypothesized that body shape metrics influence the anatomy of spinal canal and intraabdominal pressure in three dimensions. We explored the effects of abdominal circumference, trunk length, and their combination on the level of spinal anesthesia in the term parturient in this study. ⋯ TL/AC2, which simulated the ratio of the long axis and transection area of the abdomen, was correlated with maximal spinal level, and parturients with low TL/AC2 values tended to have higher dermatomal levels during spinal anesthesia.

Review Meta AnalysisPharmacological and nonpharmacological prevention of fentanyl-induced cough: a meta-analysis.
Fentanyl-induced cough (FIC) is often observed after intravenous bolus administration of fentanyl during anesthesia induction. This meta-analysis assessed the efficacy of pharmacological and nonpharmacological interventions to reduce the incidence of FIC. We searched for randomized controlled trials comparing pharmacological or nonpharmacological interventions with controls to prevent FIC; we included 28 studies retrieved from Pub-Med, Embase, and Cochrane Library. ⋯ Lidocaine [odds ratio (OR) = 0.29, 95 % confidence interval (CI) 0.21–0.39], N-methyl-D-aspartate (NMDA) receptor antagonists (OR 0.09, 95 % CI 0.02–0.42), propofol (OR 0.07, 95 % CI 0.01–0.36), a2 agonists (OR 0.32, 95 % CI 0.21–0.48), b2 agonists (OR 0.10, 95 % CI 0.03–0.30), fentanyl priming (OR 0.33, 95 % CI 0.19–0.56), and slow injection of fentanyl (OR 0.25, 95 % CI 0.11–0.58)] were effective in decreasing the incidence of FIC, whereas atropine (OR 1.10, 95 % CI 0.58–2.11) and benzodiazepines (OR 2.04, 95 % CI 1.33–3.13) were not effective. This meta-analysis found that lidocaine, NMDA receptor antagonists, propofol, a2 agonists, b2 agonists, and priming dose of fentanyl were effective in preventing FIC, but atropine and benzodiazepines were not. Slow injection of fentanyl was effective in preventing FIC, but results depend on the speed of administration.

ReviewKidney function after the intraoperative use of 6 % tetrastarches (HES 130/0.4 and 0.42).
Concerns about the nephrotoxicity of tetrastarches have recently increased with the accumulation of new evidence, particularly in relationship to septic patients. Two meta-analyses in 2011 and early 2012 also raised concerns about nephrotoxicity in surgical patients and prompted the present review of the nephrotoxicity of tetrastarches solely in the surgical setting. ⋯ Six of the seven studies did not show any adverse renal outcomes following the intraoperative use of tetrastarch, although their data are not robust enough to confirm definitive safety. Moreover, balanced electrolyte solutions are strongly recommended as a carrier solution for tetrastarches to reduce adverse outcomes.
