Randomized Controlled TrialSurgical pleth index guided analgesia blunts the intraoperative sympathetic response to laparoscopic cholecystectomy.
Surgical noxious stimuli generate a stress response with an increased sympathetic activity, potentially affecting the perioperative outcome. Surgical Pleth Index (SPI), derived from the pulse plethysmogram, has been proposed as a tool to assess nociception-antinociception balance. The relationship between SPI and autonomic nervous system (ANS) during general anesthesia is poorly understood and it is doubtful if SPI-guided analgesia may offer advantages over the standard clinical practice. The study was designed to evaluate if SPI-guided analgesia leads to a lower sympathetic modulation compared with standard clinical practice. ⋯ SPI-guided analgesia led to a more stable sympathetic modulation but didn't seem to offer clinically relevant advantages over the standard clinical practice for laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative StudyIndirect videolaryngoscopy using Macintosh blades in patients with non-anticipated difficult airways results in significantly lower forces exerted on teeth relative to classic direct laryngoscopy; a randomized crossover trial.
Videolaryngoscopy has proven advantageous over direct laryngoscopy for a variety of outcome variables, most importantly, making laryngoscopy more successful. We tested whether three videolaryngoscopes (VLS), McGrath® series 5 (Aircraft Medical Ltd, Edinburgh, UK), C-MAC® (Karl Storz, Tuttlingen, Germany) and GlideScope® Cobalt (Verathon Medical, Bothell, WA, USA) exert reduced forces on maxillary incisors and lower teeth, and compared them with a classic Macintosh MAC 3 laryngoscope blade during laryngoscopy. ⋯ Forces exerted on maxillary incisors are lower using video-assisted Macintosh blade laryngoscopy compared to classic direct laryngoscopy. The number and magnitude of forces applied to maxillary incisors also differ substantially between different VLS.

ReviewEpidural steroid injections: update on efficacy, safety, and newer medications for injection.
The best evidence for epidural injection appears to be in the setting of radicular pain with epidural steroid and non-steroid injections more efficacious than non-epidural injections. Studies showed the efficacy of non-particulate steroid to approach the efficacy of particulate steroid and very limited comparisons demonstrated no significant difference between epidural steroid and epidural non-steroid (local anesthetic) injection. Preliminary studies evaluating epidural injection of disease modifying anti-rheumatic drugs such etanercept and tocilizumab showed conflicting results and had significant limitations. ⋯ Therefore non-particulate steroid should be used in initial transforaminal epidural injection. Future studies should look into the role of adjunct diagnostic aids, including digital subtraction angiography, in detecting intravascular injection and the ideal site of needle placement, whether it is the safe triangle or the triangle of Kambin. Finally, the role of epidural disease -modifying antirheumatic drugs in the management of back pain needs to be better elucidated.

Review Meta AnalysisStatin therapy in critically-ill patients with severe sepsis: a review and meta-analysis of randomized clinical trials.
While statins are indicated to reduce blood cholesterol levels, they also have anti-inflammatory and immunomodulatory effects. Several observational cohort studies suggested that statins may improve survival and reduce complications in patients with sepsis. Recent randomized controlled studies in critically ill patients have been conducted and published. In this paper we present a meta-analysis of these randomized trials. ⋯ An electronic article search through PubMed was performed. Only randomized controlled trials including critically ill adult patients with severe sepsis were retained. A meta-analysis was performed as detailed in text below. Overall analysis including 1818 patients total from 4 studies showed that there was no difference in 60-day mortality between statins (223/903) and placebo (233/899) [risk ratio, 0.930; 95% CI, 0.722 to 1.198]. Similarly, no difference in 28-day mortality was observed between groups (statins 191/907, placebo 199/911; risk ratio 0.953; 95% CI, 0.715 to 1.271). The results of this meta-analysis confirm that the use of statin therapy should not be recommended in the management of severe sepsis in critically ill patients. Statins should be continued with caution and only if necessary, as one study reported that the statin group had a higher rate of hepatic and renal failure.

Multicenter StudyModerate-degree acidosis is an independent determinant of postoperative bleeding in cardiac surgery.
Acidosis is a well-known factor leading to coagulopathy. It has been widely explored as a risk factor for severe bleeding in trauma patients. However, no information with respect to acidosis as a determinant of postoperative bleeding in cardiac surgery patients exists. The aim of this study was to investigate the role of acidosis and hyperlactatemia (HL) in determining postoperative bleeding and need for surgical revision in cardiac surgery patients. ⋯ Even a moderate degree of postoperative acidosis is associated with a greater postoperative bleeding and surgical revision rate in cardiac surgery patients. Correction of acidosis with bicarbonate does not lead to an improvement of the postoperative bleeding asset.
