Case ReportsAlternation of one-lung and two-lung ventilations with the same single-lumen endobronchial tube during thoracoscopic surgery--a case report.
One-lung ventilation is sometimes necessary for procedures performed through thoracotomy. Single lumen endobronchial tube has been used purposefully for one lung ventilation since 1931. However, there are no reports on intra-operative alternation of one-lung and two-lung ventilations through the same single lumen endobronchial tube as it can only provide unilateral lung ventilation. We present a case in whom a tube exchanger was used to readjust tube position so as to provide alternation of one-lung and two-lung ventilations in a thoracoscopic procedure.

Case ReportsPatient-controlled epidural analgesia for postherpetic neuralgia in an HIV-infected patient as a therapeutic ambulatory modality.
A 43-year-old HIV-positive male was referred to our pain clinic one month after his fourth attack of herpes zoster infection. He complained of intermittent intolerable sharp and lancinating pain accompanied by numbness over the inner aspect of the left upper extremity, left anterior chest wall and the back. Physical examination revealed allodynia over the left T1 and T2 dermatomes without any obvious skin lesion. ⋯ Epidural PCA was discontinued after 28 days. He did not complain of pain thereafter but reported a slight numb sensation still over the lesion site for a period of time. In conclusion, postherpetic neuralgia in an HIV-infected man was successfully treated with ambulatory therapeutic modality of epidural PCA for 28 days.

Preoperative evaluation and postoperative prediction of hemostatic function with thromboelastography in patients undergoing redo cardiac surgery.
Patients who receive cardiac procedures, in particular "redo" ones, often suffer complications from massive bleeding, largely due to bypass-induced coagulopathies. Cardiopulmonary bypass (CPB) may cause damage of the blood components, both in terms of quality and quantity. In order to investigate the qualitative changes of blood constituents with special regard to coagulation resulting from the complex insult of previous cardiac surgery, thromboelastography (TEG) was used to analyze the whole clotting process. ⋯ We concluded that thromboelastography failed to predict postoperative hemorrhage in "redo" cardiac patients and the graphic recordings derived could not be treated as a guide of transfusion therapy. We thought that inferior preoperative hemostatic status and severer coagulopathy might be responsible for the differences between "redo" and primary cardiac patients.

Randomized Controlled Trial Comparative Study Clinical TrialIntradermal injection of tramadol has local anesthetic effect: a comparison with lidocaine.
We observed that intravenous retention of tramadol with a pneumatic tourniquet on the arm inflated to 70 mmHg for one minute could effectively reduce the subsequent propofol injection pain. Tramadol is a central-acting analgesic. The local analgesic effect of tramadol on reducing propofol injection pain is not well known. ⋯ We concluded that intradermal injection of tramadol or lidocaine can produce local anesthetic effect.
