Vasopressin ameliorates hypotension induced by beach chair positioning in a dose-dependent manner in patients undergoing arthroscopic shoulder surgery under general anesthesia.
The beach chair position (BCP) is associated with hypotension that may lead to cerebral ischemia. Arginine vasopressin (AVP), a potent vasoconstrictor, has been shown to prevent hypotension in BCP. It also improves cerebral oxygenation in different animal models. The present study examined the effect of escalating doses of AVP on systemic hemodynamics and cerebral oxygenation during surgery in BCP under general anesthesia. ⋯ AVP ameliorates hypotension associated with BCP in a dose-dependent manner in patients undergoing shoulder surgery under general anesthesia. However, AVP may have negative effects on SctO2 before and after BCP and on SjvO2 before BCP.

The effect of combination treatment using palonosetron and dexamethasone for the prevention of postoperative nausea and vomiting versus dexamethasone alone in women receiving intravenous patient-controlled analgesia.
The purpose of this study was to evaluate the effect of palonosetron combined with dexamethasone for the prevention of PONV compared to dexamethasone alone in women who received intravenous patient-controlled analgesia (IV-PCA) using fentanyl. ⋯ Palonosetron combined with dexamethasone was more effective in preventing PONV compared to dexamethasone alone in women receiving IV-PCA using fentanyl.

The optimal anesthetic depth for interventional neuroradiology: comparisons between light anesthesia and deep anesthesia.
This study was designed to determine the optimal anesthetic depth for the maintenance and recovery in interventional neuroradiology. ⋯ BIS values between 50 and 59 for interventional neuroradiology were associated with a more rapid recovery and favorable hemodynamic response, but also with more patient movement. We suggest that maintaining BIS values between 40 and 49 is preferable for the prevention of patient movement during anesthesia for interventional neuroradiology.

Comparison of the rate of successful endotracheal intubation between the "sniffing" and "ramped" positions in patients with an expected difficult intubation: a prospective randomized study.
Optimal head and neck positioning and clinical experience are important factors for successful endotracheal intubation in patients with a difficult airway. This study aimed to investigate the rate of successful endotracheal intubation between the sniffing and ramped positions in patients with an expected difficult intubation. ⋯ Ramped position and clinical experience can be important factors for laryngeal view and success rate of endotracheal intubation in patients with an expected difficult intubation.

Epidural anesthesia for pilonidal sinus surgery: ropivacaine versus levobupivacaine.
Epidural anesthesia is one of the best options for lower abdominal and lower limb surgery. However, there have been insufficient reports regarding the use of epidural anesthesia for pilonidal sinus surgery. The present study was performed to compare the clinical profiles of epidural block performed with 0.75% levobupivacaine and 0.75% ropivacaine in this procedure. ⋯ In patients undergoing pilonidal sinus surgery, both levobupivacaine and ropivacaine produce rapid and excellent epidural block without leading to motor block or significant side effects. Although not statistically significant, the onset time of anesthesia was shorter and the duration of effect was longer with ropivacaine than with levobupivacaine in this study.
