Takashi Hitosugi, Takeshi Mitsuyasu, Takeshi Yokoyama, Cleft-lip-plate patient with tracheobronchomalacia: A case report and review of the literature in Japan, JPRAS Open. Volume 26, December 2020, Pages 60-68, https://doi.org/10.1016/j.jpra.2020.09.003, 2020.09, The study describes a case of cleft-lip-plate (CL/P) in a 7-month-old Japanese female with TBM and Tetralogy of Fallot syndrome. Before undergoing cleft-lip surgery, her TBM was not fully elucidated by preoperative examinations, and the operation was completed uneventfully. After the surgery, however, she started showing severe respiratory distress and developed hypoxia and bradycardia in the operating room. CPR was performed successfully, but a bronchoscopy revealed a severely collapsed airway, and the pathological condition was diagnosed as TBM occurred postoperatively. Eight months later, she died of sudden respiratory failure similar to that of the postoperative event caused by TBM. A literature review was conducted on the complications of CL/P from 1990 to 2017 in Japan.
Conclusions
It was hypothesized that CL/P with congenital heart disease (CHD) and TBM with CHD may crossover in relatively high rates. Currently, there are very few solutions available to treat severe airway obstruction related to TBM. This highlights the need for preoperative diagnosis of TBM as an important step in overcoming severe airway complications.

SN Comprehensive Clinical Medicine 2019;1:650–654., SN Comprehensive Clinical Medicine 2019;1:650–654., 2019.09, Pediatric leukemia is a common cause of disease-related fatality in children aged 1 to 10 years. This disease is usually treated with a combination of chemotherapy, radiation therapy, and bone marrow transplantation. With advancements in cancer treatment, approximately 70–80% of pediatric cancer patients have been cured with these aggressive combination therapies. However, oral and dental infection, mucositis, and necrosis of tissues can occur during the cancer treatment, which may lead to morbidity and an inferior quality of life for pediatric patients with leukemia. Early detection and radical treatment reduce the risk of oral infection and its associated systemic complications. Moreover, dental treatment such as extraction or preventive treatment of teeth should be considered before the start of the cancer treatment. However, it is difficult to provide dental treatment to pediatric patients with leukemia in usual settings due to their uncooperative behavior and/or the presence of psychiatric disorders. Therefore, general anesthesia during dental treatment is often recommended for these patients. In this paper, we reviewed the anesthetic management and perioperative complications in pediatric patients with leukemia receiving general anesthesia.. |

This disease is characterized by sudden attacks of angioedema. When edema occurs in the pharynx or larynx, it can lead to serious airway compromise, including death. Physical and/or psychological stress can trigger an attack. Dental treatment, including tooth extraction, is also a recognized trigger. We report a case of a 20-year-old male with HAE who required impacted third molar extractions. C1-INH concentrate was administered 1 hour before surgery, which was completed under deep intravenous sedation. This report describes the anesthetic management of a patient with HAE and reviews treatment options and concerns.. |

It must not only provide sufficient anesthesia, but also maintain spontaneous breathing. We introduce a method to achieve this using a small dose of fentanyl and midazolam in combination with topical anesthesia. The cases of 2 patients (1 male, 1 female) who underwent oral maxillofacial surgery are reported. They received 50 µg of fentanyl 2-3 times (total 2.2-2.3 µg/kg) at intervals of approximately 2 min. Oxygen was administered via a mask at 6 L/min, and 0.5 mg of midazolam was administered 1-4 times (total 0.02-0.05 mg/kg) at intervals of approximately 2 min. A tracheal tube was inserted through the nasal cavity after topical anesthesia was applied to the epiglottis, vocal cords, and into the trachea through the fiberscope channel. All patients were successfully intubated. This is a useful and safe method for awake fiberoptic nasotracheal intubation.. |

Although its mechanism has not been clearly reported, risk factors might be positioning and prolonged operative time during oral surgeries. In addition, perioperative stressful conditions might influence the biological clock of the hair cycle. This report presents 2 cases of postoperative alopecia after oral surgery. Prevention of alopecia with type of headrest, change in head positioning, and avoidance of continuous compression is important.. |

Nasotracheal intubation for a patient with Apert syndrome can be a challenge because of abnormal facial anatomy. We experienced the anesthetic management of a patient with Apert syndrome who underwent partial resection of mandible and cleft palate repair with nasotracheal intubation. Nasotracheal intubation using a gastric tube and extubation using an airway exchange catheter proved useful in this case of airway compromise.. |
