Background: The size and depth of the double-lumen tube (DLT) are important for one-lung ventilation (OLV). In patients of a short stature, it is difficult to perform OLV successfully. We designed this study to evaluate the dimensions and margin of safety of the left main bronchi in patients of a short stature for appropriate OLV. Methods: Chest computed tomography (CT) scans of 241 patients (22 male, 219 female) of a short stature (height below 155 cm) were analyzed retrospectively. The diameters of the trachea (DT), the right and left main bronchi (DR and DL), and the lengths of the right and left main bronchi (LR and LL) were measured at the coronal section of the chest CT scans using a picture archiving communication system program. Results: There were no significant correlations between the heights and lengths of the right and left main bronchi. In addition, the ages and weights of the patients showed no significant correlations with the airway dimensions. The lengths of the bronchial lumen of the left-sided Mallinckrodt DLT show variations of 3 to 5.5 mm with tubes of identical sizes. The margin of safety is 13.8 ± 4.1 mm assuming that appropriately sized DLTs are inserted. Conclusions: For successful and safe OLV in patients of a short stature, anesthesiologists should consider the length of the main bronchus and the actual length of the bronchial lumen of the DLT.

Herpes zoster is caused by the reactivation of the varicella-zoster virus, and it typically presents as single dermatomal rash and vesicles. It can cause postherpetic neuralgia as a common complication. In immunocompromised patients, the lesions can be cutaneous, disseminated into two non-contiguous dermatomes, and this entity is referred to as herpes zoster duplex unilateralis or bilateralis. We present a case of postherpetic neuralgia after herpes zoster duplex bilateralis in a 60-year-old immunocompromised man. He had a past history of acute lymphocytic leukemia and was treated with allogeneic peripheral blood stem cell transplantation 1 year before herpes zoster reactivation. His postherpetic neuralgia pain was difficult to treat and it was refractory to conservative medication and neuraxial block.
The oropharyngeal bleeding after esophageal stethoscope insertion -A case report-

The daily insertion of endotracheal tubes, laryngeal mask airways, oral/nasal airways, gastric tubes, transesophageal echocardiogram probes, esophageal dilators and emergency airways all involve the risk of airway structure damage. In the closed claims analysis of the American Society of Anesthesiologists, 6% of all claims con- cerned airway injury. Among the airway injury claims, the most common cause was difficult intubation. Among many other causes, esophageal stethoscope is a relatively noninvasive monitor that provides extremely useful information. Relatively not many side effects that hardly is ratable. Some of that was from tracheal insertion, bronchial insertion resulting in hypoxia, hoarseness due to post cricoids inflammation, misguided surgical dissection of esophagus. Also oropharyngeal bleeding and subsequent anemia probably are possible and rarely pharyngeal/esophageal perfora- tions are also possible because of this device. Careful and gentle procedure is necessary when inserting esophageal stethoscope and observations for injury and bleeding are needed after insertion.

Background: Postoperative sore throat (POST) is a complication that undermines patient satisfaction and increases discomfort in the postoperative period. The present study examined the effects of dexamethasone gargle and endotracheal tube cuff soaking on the incidence and severity of POST. Methods: Ninety patients undergoing laparoscopic cholecystectomy were randomly allocated into three groups: 0.9% normal saline gargling and tube soaking (group C), 0.05% dexamethasone solution gargling and 0.9% normal saline tube soaking (group G), 0.9% normal saline gargling and 0.05% dexamethasone tube soaking (group S). The incidence and severity of POST were then assessed and recorded at 24 hours after surgery. Results: The total incidence of POST was significantly different among the groups (P < 0.05), and group S exhibited a significantly lower incidence of POST than group C (P < 0.0167). In addition, the POST intensity of group G and group S was less severe than those of group C (Both P < 0.0167). Conclusions: Among patients undergoing laparoscopic cholecystectomy, those who gargled with 0.05% dexamethasone solution exhibited lower severity of POST than the control group, and those whose endotracheal tube cuff was soaked in the dexamethasone solution before intubation exhibited significantly lower incidence and severity of POST than the control group.
