ReviewHow neuraxial labor analgesia differs by approach: dural puncture epidural as a novel option.
Neuraxial analgesia techniques are not limited to just standard epidural and CSE blocks. A novel approach called dural puncture epidural (DPE) which is a modification of CSE in terms of practice has gained popularity after its description and use in the obstetric population. The aim of this review is to address the practice of DPE technique as a novel option by reviewing its benefits as well as side and/or adverse effects and to understand how neuraxial labor analgesia differs by approach based on the information available in the current literature DISCUSSION: Despite controversies and concerns, more rapid onset of analgesia, early bilateral sacral analgesia, lower incidence of asymmetric block and fewer maternal and fetal side effects are provided with DPE when compared to epidural. ⋯ DPE offers a favorable risk-benefit ratio for management of neuraxial analgesia as a novel option.

ReviewSpinal myoclonus following neuraxial anesthesia: a literature review.
Spinal myoclonus (SM) is a rare neurologic movement disorder following neuraxial anesthesia (NA). SM following NA (SM-NA) has insufficient clinical information and its pathogenesis remains to be elucidated. The aim of this review article was to summarize the past cases and consider SM-NA pathophysiology. ⋯ In the LA elimination process, the large concentration differences in intrathecal LA may induce the partially functioning spinal neurons, resulting in myoclonus generation. The morphological features of the lumbar spine in women can predispose to a higher LA concentration difference. SM-NA is an unpredictable and rare neural complication following NA and should be confirmed by basic experiments and large-scale researches.

Randomized Controlled Trial Comparative StudyPeak airway pressure is lower during pressure-controlled than during manual facemask ventilation for induction of anesthesia in pediatric patients-a randomized, clinical crossover trial.
Facemask ventilation during the induction of general anesthesia in paediatric patients remains a challenge as it may result in hypoxic conditions and gastric insufflation with subsequent regurgitation and aspiration. So far, it is unclear if pressure-controlled or manual facemask ventilation is preferable in children. We hypothesized that pressure-controlled ventilation in apnoeic children results in lower peak airway pressure and flow rates compared to manual ventilation at comparable respiratory rates and tidal volumes. ⋯ Pressure-controlled facemask ventilation during induction of anesthesia in pediatric patients results in lower airway pressure, and lower flow rates compared to manual ventilation, at comparable tidal and minute volumes.

The influence of morbid obesity on difficult intubation and difficult mask ventilation.
To determine the influence of morbid obesity on the incidence of difficult mask ventilation and difficult intubation. ⋯ Morbidly obese patients do not have a higher incidence of difficult intubation compared to non-morbidly obese patients. However, they have a significantly higher incidence of difficult mask ventilation. Other factors that are predictive of both difficult mask ventilation and difficult intubation include age > 46 years, male sex, and Mallampati 3-4.

What is the predictor of the intraoperative body temperature in abdominal surgery?
Inadvertent hypothermia is a relatively common intraoperative complication. Few studies have investigated predictors of body temperature change or the effect of the blanket type used with a forced-air warming device during the intraoperative period. We investigated the predictive factors of intraoperative body temperature change in scheduled abdominal surgery. ⋯ The blanket type of the forced-air warmer, age, sex, laparoscopic surgery, and BMI are predictors of intraoperative core temperature change.
