Randomized Controlled TrialContinuous quadratus lumborum block and femoral nerve block for total hip arthroplasty: a randomized study.
Continuous femoral nerve block (FNB) has been effectively used after total hip arthroplasty (THA). Recently the anterior approach to quadratus lumborum block (QLB) has been shown to produce postoperative pain relief after THA. Continuous QLB would benefit from a catheter insertion site that is farther away from the surgical site compared with continuous FNB. In this randomized controlled study, we compared analgesic effects of the two techniques in patients undergoing THA. ⋯ Analgesic effects of continuous QLB were inferior to those of continuous FNB in patients undergoing THA under the current study condition.

Effects of intravenous injection of indocyanine green on the oxygen reserve index (ORi™).
The oxygen reserve index (ORi™) is a parameter used for the noninvasive evaluation of arterial partial pressure of oxygen (PaO2), specifically in the 100-200 mmHg range. We aimed to report on the impact of indocyanine green (ICG) on the ORi™. ⋯ It is important to consider the initial rapid increase and subsequent slow decrease in ORi™ when using ICG during surgery.

Potency estimation of sugammadex for the reversal of moderate rocuronium-induced neuromuscular block: a non-randomized dose-response study.
There is no report investigating the precise potency of sugammadex for antagonizing various intensities of rocuronium-induced neuromuscular block. The aim of this study was to evaluate the ED95 of reversibility of sugammadex and reveal the safety factor of 2 mg/kg of sugammadex for moderate rocuronium-induced neuromuscular block. ⋯ The ED95 of sugammadex for the recovery of T1 was significantly greater than that for the TOF ratio. However, a sugammadex dose of 2 mg/kg is equivalent to about 1.5 times the ED95 of sugammadex for reversal of moderate rocuronium-induced block, indicating its safety margin.

Correction to: Stiripentol alleviates neuropathic pain in L5 spinal nerve-transected mice.
In the original publication of the article, the value "40-μm thickness" was incorrect in the legend of Figure 4. The correct value is 10-μm thickness.

Incidence of postoperative shivering decreased with the use of acetaminophen: a propensity score matching analysis.
The incidence of postoperative shivering is known to be inversely associated with core body temperature. However, previous studies have pointed out that the threshold of shivering could be affected by peripheral temperature or anesthetic agents. These reports pointed specific drugs, though, anesthesia techniques have since advanced considerably. This study aimed to investigate factors associated with postoperative shivering in the context of the current body warming practice. ⋯ This study indicated that the development of shivering in patients receiving the anesthetic technique currently used in our hospital was associated with use of acetaminophen or volatile agents, and patient age.
