Randomized Controlled TrialRetrolaminar block: analgesic efficacy and safety evaluation.
Retrolaminar block (RLB) is a thoracic truncal block that can produce analgesia for the thoracic and abdominal wall. However, the characteristics of RLB are not well known. The aim of this study was to determine analgesic efficacy by measuring postoperative consume of patient-controlled analgesia (PCA), additional nonsteroidal antiinflammatory drug (NSAID) rescue, and opioid rescue. Our secondary analysis included assessment of the chronological change in arterial levobupivacaine concentrations after the block. ⋯ Continuous RLB was not inferior to PVB except for the first 24 h, and was satisfactory after mastectomy. RLB showed safe, low peak arterial levobupivacaine concentrations.

Randomized Controlled TrialEffect of lung-protective ventilation-induced respiratory acidosis on the duration of neuromuscular blockade by rocuronium.
The purpose of this study was to elucidate whether lung-protective ventilation-induced respiratory acidosis increased the duration of neuromuscular blockade by rocuronium. ⋯ Lung-protective ventilation-induced respiratory acidosis increased the duration of neuromuscular blockade by rocuronium.

Randomized Controlled TrialThe effects of intravenous anesthetics on QT interval during anesthetic induction with sevoflurane.
Sevoflurane is known to prolong the QT interval. This study aimed to determine the effect of the interaction between intravenous anesthetics and sevoflurane on the QT interval. ⋯ We concluded that an injection of propofol could counteract QTc interval prolongation associated with sevoflurane anesthesia induction.

Randomized Controlled TrialA randomized, double-blind trial evaluating the efficacy of palonosetron with total intravenous anesthesia using propofol and remifentanil for the prevention of postoperative nausea and vomiting after gynecologic surgery.
Palonosetron has potent and long-acting antiemetic effects for postoperative nausea and vomiting (PONV). The aim of this study was to prospectively evaluate the efficacy of palonosetron when used with total intravenous anesthesia (TIVA) using propofol and remifentanil for the prevention of PONV in patients undergoing laparoscopic gynecologic surgery. ⋯ Combining palonosetron with TIVA can be considered as a good method to prevent PONV, not only during the short postoperative period but also especially during the 6-24-h period after anesthesia.

Randomized Controlled Trial Comparative StudyA comparative analysis of the effects of sevoflurane and propofol on cerebral oxygenation during steep Trendelenburg position and pneumoperitoneum for robotic-assisted laparoscopic prostatectomy.
Steep Trendelenburg position and pneumoperitoneum during robotic-assisted laparoscopic prostatectomy (RALP) increase intracranial pressure (ICP) and may alter cerebral blood flow (CBF) and oxygenation. Volatile anesthetics and propofol have different effects on ICP, CBF, and cerebral metabolic rate and may have different impact on cerebral oxygenation during RALP. In this study, we measured jugular venous bulb oxygenation (SjO2) and regional oxygen saturation (SctO2) in patients undergoing RALP to evaluate cerebral oxygenation and compared the effects of sevoflurane and propofol. We also verified whether SctO2 may be an alternative to SjO2. ⋯ Sevoflurane maintains higher SjO2 levels than propofol during RALP. SctO2 does not accurately reflect SjO2.
