Randomized Controlled Trial Comparative StudyDexmedetomidine: an alternative for epidural anesthesia in tension-free vaginal-tape surgery.
Anesthetic management of tension-free vaginal-tape (TVT) procedures is sometimes difficult to deal with, especially when surgeons request a cough test. Dexmedetomidine has unique sedative and analgesic properties while having minimal respiratory effects, making it suitable for perioperative use in monitored anesthesia care. We aimed to compare dexmedetomidine and epidural anesthesia in TVT patients. ⋯ Dexmedetomidine can be an alternative to epidural anesthesia in TVT procedure requiring cough test.

Randomized Controlled Trial Comparative StudyAntiemetic prophylaxis in thyroid surgery: a randomized, double-blind comparison of three 5-HT3 agents.
The aim of this double-blind randomized study was to compare the antiemetic efficacy of three 5-hydroxytryptamine type 3 antagonists in terms of the incidence and intensity of postoperative nausea and vomiting (PONV) in a homogenous group of female patients undergoing thyroidectomy. ⋯ Among the female patients of this study undergoing thyroid surgery, granisetron 3 mg provided the best prophylaxis from PONV. Ondansetron 4 mg was equally effective, but its action lasted only 6 h, whereas tropisetron 5 mg was found ineffective.

Case ReportsPostoperative respiratory failure caused by acute exacerbation of idiopathic interstitial pneumonia.
We herein report a case of postoperative respiratory failure caused by acute exacerbation of undiagnosed interstitial pneumonia (IP). A 76-year-old woman underwent two subsequent operations, cholecystectomy and resection of lipoma in the neck, under general anesthesia at an interval of 12 days. Although the postoperative course of the first operation was uneventful, the patient abruptly developed respiratory failure on the 4th postoperative day (POD) of the second operation. ⋯ Thus, we concluded that idiopathic IP had gradually advanced preoperatively, and acute exacerbation was triggered by perioperative stress. The present case warned us that acute exacerbation of IP could occur in a patient with mild symptoms. Therefore, preoperative proper diagnosis is thought to be important as acute exacerbation of IP is a highly morbid clinical event.

Randomized Controlled TrialCharacteristics of unilateral spinal anesthesia at different speeds of intrathecal injection.
Unilateral spinal anesthesia is performed to provide restriction of sympathetic and motor block. The purpose of this study is to compare the effect of different speeds of intrathecal injection on unilateral spinal anesthesia. ⋯ The result of the study show that the extra-slow injection of hyperbaric bupivacaine provided strictly unilateral sensorial and sympathetic block in 93.9 and 87.9% of the patients, respectively, and that a slow injection of low doses of hyperbaric 0.5% bupivacaine 1 ml was sufficient to provide unilateral spinal anesthesia.
