Randomized Controlled Trial
Utility of oxygen insufflation through working channel during fiberoptic intubation in apneic patients: a prospective randomized controlled study.
Airway management is a part of routine anesthetic procedures; however, serious complications, including hypoxia and death, are known to occur in cases of difficult airways. Therefore, alternative techniques such as fiberoptic bronchoscope-assisted intubation (FOB intubation) should be considered, although this method requires more time and offers a limited visual field than does intubation with a direct laryngoscope. Oxygen insufflation through the working channel during FOB intubation could minimize the risk of desaturation and improve the visual field. Therefore, the aim of this prospective randomized controlled study was to evaluate the utility and safety of oxygen insufflation through the working channel during FOB intubation in apneic patients. ⋯ These findings suggest that oxygen insufflation through the working channel during FOB intubation aids in extending the apneic window during the procedure.

Randomized Controlled Trial
Effects of thiamine on vasopressor requirements in patients with septic shock: a prospective randomized controlled trial.
Thiamine, an essential vitamin for aerobic metabolism and glutathione cycling, may decrease the effects of critical illnesses. The objective of this study was to determine whether intravenous thiamine administration can reduce vasopressor requirements in patients with septic shock. ⋯ Thiamine was not associated to a significant reduction in vasopressor-free days over 7-days in comparison to placebo in patients with septic shock. Administration of thiamine could be associated with a reduction in vasopressor dependency index and lactate level within 24 h. The study is limited by early stopping and low sample size.

Randomized Controlled Trial
Postoperative analgesic efficacy of ear acupuncture in patients undergoing abdominal hysterectomy: a randomized controlled trial.
Numerous studies have revealed that acupuncture can increase the somatic pain threshold. Electro-acupuncture (EA) can help pain-relieving with minimal physiologic disturbance. Various painful disorders, as well as pain following various surgeries, like cesarean section, gastrostomy, and enterectomy were managed properly with acupuncture. Therefore we studied the postoperative analgesic effect of EA in patients undergoing abdominal hysterectomy. ⋯ Electric ear acupuncture provides postoperative analgesia, reducing morphine requirement and consequently its side effects.

Observational Study
Effects of the anesthesiologist's experience on postoperative hoarseness after double-lumen endotracheal tube intubation: a single-center propensity score-matched analysis.
Postoperative hoarseness after general anesthesia is associated with patient discomfort and dissatisfaction. A recent large retrospective study showed that single-lumen endotracheal tube intubation by a trainee did not alter the incidence of postoperative pharyngeal symptoms compared with intubation by a senior anesthesiologist. However, there is limited information about the relationship between the anesthesiologist's experience and hoarseness after double-lumen endotracheal tube intubation. We tested the hypothesis that double-lumen endotracheal tube intubation performed by a trainee increases the incidence of postoperative hoarseness compared to intubation by a senior anesthesiologist. ⋯ Double-lumen endotracheal tube intubation by trainee anesthesiologists with < 2 years of experience increased the incidence of postoperative hoarseness 24 h after surgery compared to intubation by senior anesthesiologists with ≥2 years of experience.
