Spondyloepiphyseal dysplasia congenita (SEDC) is a type of short-limbed dwarfism characterized by platyspondylia, delayed metaphyseal ossification, and irregularly shaped bones. Anesthetic issues in patients with SEDC have reportedly included airway stenosis caused by laryngotracheal hypoplasia, ventilation difficulty due to facial hypoplasia, and intubation difficulty attributed to microgenia. Furthermore, atlantoaxial instability can lead to cervical dislocation due to excessive or violent manipulation of the head and neck.

We encountered a case in which anisocoria in the left and right eyes was noticed after induction of general anesthesia, and the surgery was canceled. The patient was a 53-year-old woman with a history of hypertension.

However, the efficacy of low-dose fentanyl (FEN) in combination with DEX and MZ sedation remains unclear. Therefore, we implemented a prospective randomised controlled trial to investigate the intra- and postoperative analgesic effects, intraoperative respiratory and circulatory dynamics, and frequency of intra- and postoperative adverse events of continuous low-dose fentanyl administration with DEX and MZ sedation.

- Rocuronium bromide (RB) can cause vascular pain, and this study aimed to explore whether diluting it affects both the pain experienced by patients and the time it takes for muscle relaxation to begin.
- In the study, 39 patients were split into three groups receiving different concentrations of RB: full strength (10 mg/ml), two-fold diluted (5 mg/ml), and three-fold diluted (3.3 mg/ml), with muscle relaxation onset and pain levels measured after administration.
- Results showed no significant differences in pain levels across the groups, but the three-fold diluted group experienced a significantly slower onset of muscle relaxation compared to the full-strength group, suggesting that RB does not need to be diluted if a large vein is used
Article Synopsis
- The study evaluated the effectiveness of the McGrath MAC video laryngoscope for routine nasotracheal intubation by comparing it to the Airway scope and Macintosh laryngoscope in a group of 60 adult patients undergoing elective oral surgery.
- Results showed that the McGrath MAC had a significantly shorter intubation time (26.8 seconds) compared to the other two devices, which averaged over 36 seconds.
- The McGrath MAC also provided better visualization during intubation, as indicated by improved Cormack Lehane grading, suggesting it is a more efficient option for nasotracheal intubation.
Modified electroconvulsive therapy (m-ECT) is a treatment for mental disease such as depressive disorder. Although a muscle relaxant is used during current application, strong occlusion occurs due to the proximity of the electrode to the temporal and masseter muscles. Although a feedback mechanism to avoid excessive occlusion occurs unconsciously, the mechanism does not work under general anesthesia.

The primary palate-related effects of sevoflurane on developing A/J strain mouse embryos (embryos) were studied using a whole-embryo culture (WEC) system. This system could separate the direct effects of sevoflurane from those that are maternally mediated.
