Optimal location of local anesthetic injection into the interspace between the popliteal artery and posterior capsule of the knee (iPACK) for posterior knee pain after total knee arthroplasty: an anatomical and clinical study.
This study aimed to determine the optimal location of local anesthetic injection in the interspace between the popliteal artery and posterior capsule of the knee (iPACK), using the anatomical pattern of the articular branch of tibial nerve (ABTN). We hypothesized that injection at the level of ABTN forming a popliteal plexus would mainly spread throughout the popliteal fossa without contacting the tibial or peroneal nerves. ⋯ We described a modified iPACK technique injection at the level of the ABTN forming the popliteal plexus, and it may constitute an optional anesthetic regimen to promote early ambulation following TKA.

Case ReportsSerratus anterior plane block combined with monitored anesthesia care for surgery of lateral side of breast -a case report.
In breast surgery, regional anesthesia rather than primary anesthesia has been mainly used for postoperative analgesia. Serratus anterior plane block is a new method for ultrasound-guided thoracic wall block. It is less invasive and relatively safer than conventional regional anesthetic techniques. ⋯ Serratus anterior plane block might be simple and effective technique for breast surgery when a lesion is located on lateral side.

Effects of dexamethasone and hydrocortisone on rocuronium-induced neuromuscular blockade and reversal by sugammadex in a rat.
The facilitator effects of steroids on neuromuscular transmission may cause resistance to neuromuscular blocking agents. Additionally, steroids may hinder sugammadex reversal of neuromuscular blockade, but these findings remain controversial. Therefore, we explored the effect of dexamethasone and hydrocortisone on rocuronium-induced neuromuscular blockade and their inhibitory effect on sugammadex. ⋯ Acute exposure to steroids did not resist the neuromuscular blockade caused by rocuronium. And inhibition of sugammadex reversal on rocuronium-induced neuromuscular blockade is unlikely at typical clinical doses of dexamethasone and also hydrocortisone. Conclusively, we can expect proper effects of rocuronium and sugammadex when dexamethasone or hydrocortisone is used during general anesthesia.

Comparative StudyAssessment of phase-lag entropy, a new measure of electroencephalographic signals, for propofol-induced sedation.
Phase-lag entropy (PLE) was recently described as a measurement of temporal pattern diversity in the phase relationship between two electroencephalographic signals from prefrontal and frontal montages. This study was performed to evaluate the performance of PLE for assessing the depth of sedation. ⋯ PLE is a new and reliable consciousness monitoring system for assessing the depth of sedation induced by propofol, which is comparable with the BIS.
