Wolf-Hirschhorn syndrome is a rare hereditary disease that results from a 4p chromosome deletion. Patients with this syndrome are characterized by craniofacial dysgenesis, seizures, growth delay, intellectual disability, and congenital heart disease. Although several cases have been reported, very little information is available on anesthetic management for patients with Wolf-Hirschhorn syndrome. We encountered a case requiring anesthetic management for a 2-year-old girl with Wolf-Hirschhorn syndrome. The selection of an appropriately sized tracheal tube and maintaining intraoperatively stable hemodynamics might be critical problems for anesthetic management. In patients with short stature, the tracheal tube size may differ from what may be predicted based on age. The appropriate size ( internal diameter ) of tracheal tubes for children has been investigated. Congenital heart disease is frequently associated with Wolf-Hirschhorn syndrome. Depending on the degree and type of heart disease, careful monitoring of hemodynamics is important.

Damage to the endotracheal tube (ETT) during oral and maxillofacial surgeries is a rare but serious intraoperative complication. Herein, we present a case of a partially damaged ETT that was repaired using Dermabond surgical adhesive (Ethicon, Sommerville, NJ, USA) during a Lefort osteotomy. Dermabond surgical adhesive can be a simple and viable tool to repair partially transected ETTs where ETT exchange carries a high risk of airway loss. Our case adds to one of the several techniques for managing damaged ETT in an intraoperative setting.

Background: Endotracheal intubation during anesthesia induction may increase airway resistance ($R_{aw}$) and decrease dynamic lung compliance ($C_{dyn}$). We hypothesized that prophylactic treatment with a transdermal ${\beta}2$-agonist tulobuterol patch (TP) would help to reduce the risk of bronchospasm after placement of the endotracheal tube. Methods: Eighty-two American Society of Anesthesiologists (ASA) category I or II adult patients showing obstructive patterns were divided randomly into a control and a TP group (n = 41 each). The night before surgery, a 2-mg TP was applied to patients in the TP group. Standard monitors were recorded, and target controlled infusion (TCI) with propofol and remifentanil was used for anesthesia induction and maintenance. Simultaneously, end-tidal carbon dioxide, $R_{aw}$, and $C_{dyn}$ were determined at 5, 10, and 15 min intervals after endotracheal intubation. Results: There was no significant difference in demographic data between the two groups. The TP group was associated with a lower $R_{aw}$ and a higher $C_{dyn}$, as compared to the control group. $R_{aw}$ was significantly lower at 10 min (P < 0.05) and 15 min (P < 0.01), and $C_{dyn}$ was significantly higher at 5 min (P < 0.05) and 15 min (P < 0.01) in the TP group. A trend towards a lower $R_{aw}$ was observed showing a statistically significant difference 5 min after endotracheal intubation (P < 0.01) in each group. Conclusions: Prophylactic treatment with TP showed a bronchodilatory effect through suppressing an increase in $R_{aw}$ and a decrease in $C_{dyn}$ after anesthesia induction without severe adverse effects.

Purpose: Since its implementation, flexible fiberoptic bronchoscopy (FBS) has played an important role in the diagnosis and treatment of tracheobronchial tree and pulmonary disease. Although FBS is often performed by endoscopists, it has also been performed by surgeons, albeit rarely. This study investigated FBS from the surgeon's perspective. Methods: This retrospective study included patients who underwent FBS performed by a single thoracic surgeon between March 2017 and December 2021. Accordingly, the epidemiology, purpose, results, and complications of FBS were analyzed. Results: A total of 47 patients received FBS, whereas 13 patients underwent repeat FBS. Their mean age was 60.7 years. The main organs injured involved the chest (n=22), brain (n=9), abdominal organ (n=7), cervical spine (n=4), extremities (n=4), and face (n=1). The average Injury Severity Score was 22.5. Indications for FBS included atelectasis or haziness on chest x-ray (n=34), pneumonia (n=17), difficult ventilator management (n=7), percutaneous dilatory tracheostomy (n=3), blood aspiration (n=2), foreign body removal (n=2), and intubation due to a difficult airway (n=1). The findings of FBS were mucous plugs (n=36), blood and blood clots (n=16), percutaneous dilatory tracheostomy (n=3), foreign bodies (n=2), granulation tissue at the tracheostomy site (n=2), tracheostomy tube malposition (n=1), bronchus spasm (n=1), difficult airway intubation (n=1), and negative findings (n=5). None of the patients developed complications. Conclusions: FBS is an important modality in the trauma field that allows for the possibility of diagnosis and therapy. With sufficient practice, surgeons may safely perform FBS at the bedside with relative ease.

Purpose: The purpose of this study was to identify the effects of the heated-humidified breathing circuit applied on the body temperature, shivering, and thermal comfort of general anesthesia patients. Methods: The participants were patients who received general anesthesia at University Hospital K located in City B, with 25 patients in the experimental group and 25 patients in the control group. The period of this study was from Mar 19 to Apr 26, 2019. The experimental equipment included a heated-humidified breathing circuit, which connects the intubation tube with the anesthesia machine for mechanical ventilation after airway intubation in general anesthesia patients. Results: The body temperature, shivering, and thermal comfort after surgery were significantly different between the two groups (p<.001). However, the body temperature during surgery was slightly different between the experimental group and the control group. Conclusion: A heated-humidified breathing circuit may be actively used in a warming method to prevent the hypothermia of general anesthesia patients.

Although many factors associated with difficult intubation have been known, predictors of difficult mask ventilation are not well known. We experienced a case of nearly complete airway obstruction following usual anesthetic induction which needed various emergency treatments. The patient had a preoperative diagnosis of contact granuloma of right posterior vocal cord and bilateral vocal cord palsy but later was found out as invasive laryngeal cancer. Upon the surgical field of view, both vocal cords were showing significantly thickened and fixated appearance and was considered as in the critical narrowing state with the potential of complete obstruction. Using $C-MAC^{(R)}$ video laryngoscope we were able to see the narrowed vocal cord and choose proper size of endo-tracheal tube. Consequently, intubation was successfully done and operation was conducted. From this case, we have lessons that physicians should examine the patient's airway more carefully in case of laryngeal mass and prepare emergency measures.

Despite improvement in respiratory care, including use of low pressure and high volume cuffed tubes, tracheal stenosis remains a serious complication after a long-term tracheal intubation and tracheostomy. In such patients, tracheal resection and primary anastomosis is still considered ideal therapeutic modality. Between 1989 and 1997, we performed tracheal resections with end-to-end anastomosis on 14 patients with no operative mortality and some morbidity. Tracheal stenosis was caused by tracheostomy in nine patients, by endotracheal intubation in three patients and by thyroid carcinoma in two patients. The length of stenosis was various from 2cm to 4.5cm. All patient underwent segmental tracheal resection and primary anastomosis(14 patients) and additional procedures were cricoid cartilage reconstruction(2 patients), suprahyoid laryngeal release(3patients), carinal release technique(2 patients) and arytenoidectomy(2 patients). We have nine complications: granulona at anastomosis site in four patients, vocal cord palsy in two patients and restenosis, pneumonia, skin necrosis in each of those patients. The granuloma was removed by bronchoscopic forceps(4 patients). Vocal cord palsy was treated by arytenoidectorny(2 patients), restenosis by T-tube insertion, pneumonia by antibiotics and skin necrosis was treated by skin graft. We reviews our expenence of clinical features of tracheal stenosis and surgical treatment by tracheal one-to-end anastomosis with additional procedures to avoid postoperative complications for sucessful results.

Acquired tracheal dilatation is a state of abnormal tracheal dilatation developing from various causes. Tracheomalacia and tracheal dilatation can develop in respiratory distress patients with prolonged endotracheal intubation with assisted positive-pressure ventilation due to positive airway pressure and high cuff pressure. The authors have recently experienced one case of respiratory failure, cardiac arrest, and whole body emphysema after tracheostomy and portex tube insertion were performed to patient with the endotracheal intubation with assisted positive-pressure ventilation for two weeks in the septic shock resulted from colon perforation, who developed tracheal dilatation. We summarize diagnostic and therapeutic strategies of acquired tracheal dilatation for the prevention of emergency status and the management for that patients.
