Randomized Controlled Trial Comparative Study
Influence of the timing of administration of crystalloid on maternal hypotension during spinal anesthesia for cesarean delivery: preload versus coload.
Prophylactic fluid preloading before spinal anesthesia has been a routine procedure to prevent maternal hypotension during cesarean delivery. Unlike colloid, timing of infusion of crystalloid may be important because of its short stay in intravascular space. We hypothesized that crystalloid loading just after intrathecal injection compared to preload would be more effective in preventing maternal hypotension. ⋯ In case of using crystalloids for cesarean delivery, coload is more effective than preload for the prevention of maternal hypotension after spinal anesthesia.

Randomized Controlled Trial Comparative Study
Techniques for the insertion of the ProSeal laryngeal mask airway: comparison of the Foley airway stylet tool with the introducer tool in a prospective, randomized study.
Many tools have been developed to facilitate the insertion of the ProSeal laryngeal mask airway (LMA) insertion, which can be impeded by folding of its soft cuff. The aim of this study was to compare the efficiency of ProSeal LMA insertion guided by a soft, direct optical Foley Airway Stylet Tool (FAST) with the standard introducer tool (IT). ⋯ Both FAST-guided and IT-assisted techniques achieved correct ProSeal LMA positioning, but the IT technique was significantly quicker and less likely to cause a sore throat.

Gastric tube insertion under direct vision using the King Vision™ video laryngoscope: a randomized, prospective, clinical trial.
The frequency of malpositioning of gastric tubes in the trachea has been reported to be 0.3-15%, which may cause severe complications, such as pneumonia, if not detected promptly. If a gastric tube can be guided into the esophagus under direct vision with a video laryngoscope, misplacement of the gastric tube into the trachea can be avoided. We compared gastric tube insertion under direct vision using a video laryngoscope with the conventional method of blind insertion. ⋯ Gastric tube insertion using a King Vision video laryngoscope was straightforward, and was particularly useful for detecting and correcting tracheal malpositioning.

Randomized Controlled Trial
Palonosetron and aprepitant for the prevention of postoperative nausea and vomiting in patients indicated for laparoscopic gynaecologic surgery: a double-blind randomised trial.
Postoperative nausea and vomiting (PONV) is one of the most common postsurgical complications. Palonosetron, a 5-hydroxytryptamine receptor antagonist, is effective for PONV prevention. Herein, we compared palonosetron and aprepitant (a neurokinin-1 receptor antagonist) for PONV prevention in patients indicated for laparoscopic gynaecologic surgery. ⋯ Palonosetron and aprepitant were both effective for PONV prevention in the patients indicated for laparoscopic gynaecologic surgery. The drugs can be used in combination for multimodal therapy because they bind to different receptors. More research is needed to evaluate the effects of aprepitant on pain management in humans.

Liberal or restricted fluid administration: are we ready for a proposal of a restricted intraoperative approach?
Fluid management in the perioperative period has been extensively studied but, despite that, "the right amount" still remains uncertain. The purpose of this paper is to summarize the state of the art of intraoperative fluid approach today. ⋯ An intraoperative restrictive fluid approach in major surgery may be beneficial while Goal-directed Therapy should be superior to the liberal fluid strategy. Finally, we propose a rational approach currently used at our institution.
