Review Meta Analysis
What is the place of clonidine in anesthesia? Systematic review and meta-analyses of randomized controlled trials.
Clonidine improves post-operative analgesia, reduces nausea & vomiting, improves hemodynamic stability, does not prolong wakening, and does not improve cardiac outcomes.

Randomized Controlled Trial Comparative Study
Randomized trial of a novel double lumen nasopharyngeal catheter versus traditional nasal cannula during total intravenous anesthesia for gastrointestinal procedures.
Patients undergoing general anesthesia routinely experience episodes of hypoxemia. There are multiple causes of procedural oxygen desaturation including upper airway obstruction and central hypoventilation. We hypothesize that oxygen supplementation via nasopharyngeal catheter (NPC) will decrease the number of episodes of hypoxemia as compared to traditional NC oxygen supplementation in patients undergoing general anesthesia provided by an anesthesia provider for gastrointestinal endoscopy procedures. ⋯ Oxygen supplementation via a nasopharyngeal catheter during intravenous general anesthesia resulted in significantly fewer episodes of hypoxemia and number of airway assist maneuvers. Future studies are needed to assess the utility of NPC in other clinical environments where supplemental oxygen is required in the setting of potential airway obstruction.

Review Meta Analysis Comparative Study
Commonly-used versus less commonly-used methods in the loss of resistance technique for identification of the epidural space: A systematic review and meta-analysis of randomized controlled trials.
To summarize the efficacy of less-commonly used modern methods (e.g. epidrum, lidocaine, acoustic device, Macintosh balloon) compared to more commonly-used methods (i.e. air, saline, both) in the loss of resistance technique for identification of the epidural space. ⋯ Moderate-quality evidence shows that less commonly-used modern methods such as epidrum, lidocaine and acoustic devices, are more efficacious compared to more commonly-used methods (i.e. air, saline, both) in terms of the loss of resistance technique for identification of the epidural space. These findings should be explored further in the context of the clinical practice among anaesthesiologists.

Clinical Trial
The impact of anesthesia on hemodynamic and volume changes in operative hysteroscopy: a bioimpedance randomized study.
Operative hysteroscopy is accompanied by the use of distention medium. Its absorption can lead to volume overload and hemodynamic disturbances that can lead to serious complications. We investigated the impact of the type of anesthesia on decreasing these complications with the use of noninvasive thoracic bioimpedance. ⋯ Spinal anesthesia is associated with less glycine absorption, less thoracic fluid load, better control of hemodynamics, and better patient satisfaction in operative hysteroscopy.
