The optimal volume of 0.2% ropivacaine required for an ultrasound-guided stellate ganglion block.
This study was performed to find the optimal volume of local anesthetics needed for a successful ultrasound-guided stellate ganglion block (SGB) to treat head and neck pathology. ⋯ This data suggests that the optimal volume of 0.2% ropivacaine for ultrasound-guided SGB to treat the head and neck pathology in daily practice is 4 ml.

Remifentanil-induced pronociceptive effect and its prevention with pregabalin.
Experimental and clinical studies have suggested that remifentanil probably causes acute tolerance or postinfusion hyperalgesia. This study was designed to confirm whether remifentanil given during propofol anesthesia induced postoperative pain sensitization, and we wanted to investigate whether pregabalin could prevent this pronociceptive effect. ⋯ The results of this study show that remifentanil added to propofol anesthesia causes pain sensitization in the immediate postoperative period. Pretreatment with pregabalin prevents this pronociceptive effect and so this may be useful for the management of acute postoperative pain when remifentanil and propofol are used as anesthetics.

Epidural anesthesia for cesarean section in a patient with Marfan syndrome and dural ectasia -A case report-.
Pregnancy is considered a period of high risk for cardiovascular complications in patients with Marfan syndrome. Therefore the choice of anesthetic technique for delivery should be focused on minimizing hemodynamic fluctuations, and preferably provide adequate post-operative pain control. ⋯ However, dural ectasia is present in 63-92% of patients with Marfan syndrome, and the increased amount of cerebrospinal fluid volume is thought to be one of main reasons for spinal anesthesia failure. We report herein the peri-operative management of a patient with Marfan syndrome and dural ectasia for cesarean section using epidural anesthesia.

Comparison of volume-controlled and pressure-controlled ventilation using a laryngeal mask airway during gynecological laparoscopy.
Several publications have reported the successful, safe use of Laryngeal Mask Airway (LMA)-Classic devices in patients undergoing laparoscopic surgery. However, there have been no studies that have examined the application of volume-controlled ventilation (VCV) or pressure-controlled ventilation (PCV) using a LMA during gynecological laparoscopy. The aim of this study is to compare how the VCV and PCV modes and using a LMA affect the pulmonary mechanics, the gas exchange and the cardiovascular responses in patients who are undergoing gynecological laparoscopy. ⋯ Our results demonstrate that PCV may be an effective method of ventilation during gynecological laparoscopy, and it ensures oxygenation while minimizing the increases of the peak airway pressure after CO(2) insufflation.
