Background: Schwannoma is a benign tumor originating from the peripheral nerve sheath. The clinical symptoms of tracheal schwannoma depend on the location of the tumor, and the most common clinical symptoms are cough and hemoptysis. The most effective treatment for benign tumors is complete resection of the primary lesion at an early stage. Our experience has demonstrated that primary tracheal schwannoma can be safely excised with a high-frequency electric knife in a minimally invasive manner.
Case Summary: We report a 61-year-old asymptomatic woman who underwent chest computed tomography (CT), which accidentally found an intraluminal tracheal mass without enlarged lymph nodes. Then, the patient underwent bronchoscopy, which found that the tracheal mass originated from the left wall of the upper trachea, was less than 1.5 cm in size, immovable, smooth and 4 cm away from the vocal cord, resulting in partial upper respiratory tract obstruction. Treatment was performed using an endoscopic resection for en bloc removal of the tracheal mass. The diagnosis was primary tracheal schwannoma. A follow-up was performed after endoscopic surgery, and bronchoscopy and thoracic CT were used to monitor whether there was a recurrence. At present, there is no evidence of recurrence, and the patient had a good quality of life. Endoscopic resection may be effective and safe in the treatment of primary tracheal schwannoma.
Conclusion: Primary tracheal schwannoma is a very rare benign tumor. In this case, we cured it by complete endoscopic resection.

The Role of Patient-Controlled Epidural Analgesia in the Short-Term Outcomes of Laparoscopic-Assisted Gastrectomy in Elderly Gastric Cancer Patients.

Introduction: Patient-controlled intravenous analgesia (PCIA) and patient-controlled epidural analgesia (PCEA) constitute two major advances in pain management after major abdominal surgery. However, the role of PCIA or PCEA has not been particularly studied in elderly patients with gastric cancer. The aim of this study is to make a comparison between PCIA and PCEA in terms of their performance on short-term outcomes in elderly patients undergoing laparoscopic-assisted gastrectomy.

Introduction: Patients with cerebral hemorrhage often require a tracheal intubation to protect the airway and maintain oxygenation. Due to the use of analgesic and sedative drugs during endotracheal intubation and the opening of the glottis may easily cause aspiration pneumonia. Ceftriaxone is a semi-synthetic third-generation cephalosporin with strong antimicrobial activity against most gram-positive and gram-negative bacteria.

Background: Airway management is a critical component of the care of patients experiencing cardiac arrest, but data from randomized trials on the use of video vs direct laryngoscopy for intubation in the setting of cardiac arrest are limited. Current AHA guidelines recommend placement of an endotracheal tube either during CPR or shortly after return of spontaneous circulation but do not provide guidance around intubation methods, including the choice of laryngoscope.
Research Question: Does use of video laryngoscopy improve the incidence of successful intubation on the first attempt, compared to use of direct laryngoscopy, among adults undergoing tracheal intubation after experiencing cardiac arrest?
Study Design And Methods: This secondary analysis of the Direct versus Video Laryngoscope (DEVICE) trial compared video laryngoscopy versus direct laryngoscopy in the subgroup of patients who were intubated following cardiac arrest.
Noradrenergic suppression to reduce electroencephalographic arousal after intubation: a randomised, placebo-controlled trial.

Department of Anaesthetics, Royal Prince Alfred Hospital, Sydney, NSW, Australia.
Background: Intraoperative awareness, without explicit recall, occurs after induction of anaesthesia in approximately 10% of persons under 40 yr of age. Most anaesthetic agents minimally suppress the noradrenergic system. We hypothesised that addition of dexmedetomidine, which suppresses noradrenergic activity, may reduce encephalographic (EEG) arousal in response to tracheal intubation; such an effect would lay the foundation for future studies of dexmedetomidine in reducing intraoperative awareness.
