Comparative StudyAnalysis of expert consultation referrals to the Korean Society of Anesthesiologists (KSA): a comparison of procedural sedation and general anesthesia.
Procedural sedation during diagnostic or therapeutic procedures is currently widely used by clinicians across a broad range of specialties. However, procedural sedation is a poorly controlled practice in many countries, often performed in potentially unsafe environments. ⋯ Our analysis of procedural sedation based on anesthesia-related adverse events compiled in the national database revealed a high severity of patient injury similar to that due to general anesthesia. Most procedural sedations were shown to be poorly controlled without adequate pre-procedural patient evaluation or intraoperative monitoring. Thus, it is essential to establish proper practical guidelines for procedural sedation and ensure strict adherence to these guidelines, especially during the NAAP.

Randomized Controlled Trial Comparative StudyDexmedetomidine versus remifentanil sedation during awake fiberoptic nasotracheal intubation: a double-blinded randomized controlled trial.
Awake fiberoptic nasotracheal intubation is usually performed in patients with an anticipated difficult airway. This study compares dexmedetomidine and remifentanil for conscious sedation during fiberoptic intubation. ⋯ Both dexmedetomidine and remifentanil were effective as sedatives in patients undergoing awake fiberoptic nasotracheal intubation. Compared with remifentanil, dexmedetomidine offered better endoscopy scores, lower recall of intubation, and greater patient satisfaction, with minor hemodynamic side effects.

ReviewThe recent progress in research on effects of anesthetics and analgesics on G protein-coupled receptors.
The exact mechanisms of action behind anesthetics and analgesics are still unclear. Much attention was focused on ion channels in the central nervous system as targets for anesthetics and analgesics in the 1980s. During the 1990s, major advances were made in our understanding of the physiology and pharmacology of G protein coupled receptor (GPCR) signaling. ⋯ There has been little work on G(s)- and G(i)-coupled receptors. In the last decade, a new assay system, using chimera G(i/o)-coupled receptor fused to Gq(i5), has been established and the effects of anesthetics and analgesics on the function of G(i)-coupled receptors is now more easily studied. This review highlights the recent progress of the studies regarding the effects of anesthetics and analgesics on GPCRs.

The effect of intravenous glucose solutions on neonatal blood glucose levels after cesarean delivery.
Intravenous solutions are often administered to the mother on the day of a cesarean delivery to minimize the effect of preoperative fasting or to stabilize the hemodynamics. Different intravenous solutions contain varying amounts of glucose, and rapid administration may lead to hypoglycemia in the neonate. We conducted a study to compare blood glucose levels of the mother and the fetus/neonate after they were rapidly given a Ringer's solution containing 0, 1, or 5 % glucose. The effect of the glucose load that these intravenous solutions impose during cesarean delivery has not been fully reported. Therefore, we compared the effect of 0 % (Group I, n = 15), 1 % (Group II, n = 15), and 5 % (Group III, n = 15) glucose acetated Ringer's solutions on maternal and umbilical blood glucose levels to determine the optimal glucose concentration. ⋯ The use of 1 % glucose acetated Ringer's solution did not induce hyperglycemia in the mother and it was able to maintain appropriate blood glucose levels in the fetus.
