Review Meta Analysis Comparative StudySafety and Efficacy of Volatile Anesthetic Agents Compared With Standard Intravenous Midazolam/Propofol Sedation in Ventilated Critical Care Patients: A Meta-analysis and Systematic Review of Prospective Trials.
Inhalation agents are being used in place of intravenous agents to provide sedation in some intensive care units. We performed a systematic review and meta-analysis of prospective randomized controlled trials, which compared the use of volatile agents versus intravenous midazolam or propofol in critical care units. ⋯ Volatile-based sedation demonstrates a reduction in time to extubation, with no increase in short-term adverse outcomes. Marked study heterogeneity was present, and the results show marked positive publication bias. However, a reduction in extubation time was still evident after statistical correction of publication bias. Larger clinical trials are needed to further evaluate the role of these agents as sedatives for critically ill patients.

Randomized Controlled Trial Comparative StudyTransversus Abdominis Plane Block Versus Wound Infiltration for Analgesia After Cesarean Delivery: A Randomized Controlled Trial.
Transversus abdominis plane (TAP) block and local anesthetic wound infiltration provide analgesia after cesarean delivery. Studies comparing the 2 techniques are scarce, with conflicting results. This double-blind, randomized controlled trial aimed to compare bilateral ultrasound-guided TAP block with single-shot local anesthetic wound infiltration for analgesia after cesarean delivery performed under spinal anesthesia. We hypothesized that the TAP block would decrease postoperative cumulative fentanyl consumption at 24 hours. ⋯ TAP block and wound infiltration did not significantly differ regarding postoperative fentanyl consumption, pain scores, and patient satisfaction in parturients undergoing cesarean delivery under spinal anesthesia.

ReviewTherapeutic Plasma Transfusion in Bleeding Patients: A Systematic Review.
Plasma products, including fresh frozen plasma, are administered extensively in a variety of settings from massive transfusion to vitamin K antagonist reversal. Despite the widespread use of plasma as a hemostatic agent in bleeding patients, its effect in comparison with other available choices of hemostatic therapies is unclear. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PubMed Central, and databases of ongoing trials for randomized controlled trials that assessed the efficacy and/or safety of therapeutic plasma as an intervention to treat bleeding patients compared with other interventions or placebo. ⋯ Four nonrandomized studies described the effect of therapeutic plasma in bleeding patients; however, data gathered from these studies did not allow for comparison with other therapeutic interventions primarily as a result of the low number of patients and the use of different (or lack of) comparators. We identified two ongoing trials investigating the efficacy and safety of therapeutic plasma, respectively; however, no data have been released as yet. Although plasma is used extensively in the treatment of bleeding patients, evidence from randomized controlled trials comparing its effect with those of other therapeutic interventions is currently lacking.
