Tracheal intubation is an important clinical skill for medical students and junior residents (novice intubators). They are usually trained to use a direct laryngoscope (DL) with straight-to-cuff styletted tracheal tubes first. Only later are they exposed to the bougie as an airway adjunct and videolaryngoscope (VL) with either a standard blade or a hyperangulated blade. The purpose of this study was to investigate the performance of novice intubators in using DL with 3 common stylets. ⋯ The performances of novice intubators with 3 different stylets were similar. The success rates for DL with either hyperangulated VL stylet or bougie were not inferior compared with the straight-to-cuff stylet on manikin airway training model. If we properly trained novice intubators to use corresponding maneuvers, they can learn to use the 3 stylets early in their airway learning course.

Observational Study
Retrospective observational study of the effects of residual neuromuscular blockade and sugammadex on motor-evoked potential monitoring during spine surgery in Japan.
Given neuromuscular blockade (NMB) can affect the amplitude and detection success rate of motor-evoked potentials (MEP), sugammadex may be administered intraoperatively. We evaluated the factors affecting the degree of residual NMB (i.e., the train-of-four [TOF] ratio) and the relationship between TOF ratio and MEP detection success rate in Japanese patients undergoing spine surgery. This single-center retrospective observational study included adults who underwent spine surgery under propofol/remifentanil anesthesia, received rocuronium for intubation, and underwent myogenic MEP monitoring after transcranial stimulation. ⋯ The time from intubation to the start of MEP monitoring after NMB recovery was significantly shorter in patients administered sugammadex versus patients without sugammadex (P < .0001). The MEP detection success rate was higher in patients with a TOF ratio of ≥0.75. Sugammadex shortened the time from intubation to the start of MEP monitoring after NMB recovery.

Observational Study
Risk of obstetric and neonatal morbidity in gestational diabetes in a single institution: A retrospective, observational study.
Gestational diabetes mellitus (GDM) is defined as a carbohydrate intolerance with onset or first recognition occurring during pregnancy and GDM could be risk factor for various maternal fetal complications. This study aimed to investigate risks of maternal and neonatal outcomes according to GDM and normal glucose tolerance. This retrospective, observational study included singleton pregnant women who had received a 50-g oral glucose challenge test in 2nd trimester of gestation and gave birth at National Health Insurance Service Ilsan Hospital. ⋯ Multivariate analysis, however, showed that GDM was not independent risk factor for LGA, NICU admission, and intubation rate. Compared with the non-GDM group, GDM was associated with an increased likelihood of preterm birth <37 weeks, however, did not increase cesarean delivery, postpartum hemorrhage, LGA, and NICU admission rate. This study showed that the majority of women with GDM delivered with similar maternal and neonatal outcomes in non-GDM women.
