Ultrasound-Guided Transmuscular Quadratus Lumbar Block Reduces Opioid Consumption after Laparoscopic Partial Nephrectomy.

Objectives Transmuscular quadratus lumborum block (TQLB) may provide postoperative analgesia in patients undergoing intraperitoneal surgeries. The purpose of this study was to examine the potential efficacy of TQLB among patients undergoing retroperitoneal procedures, such as the laparoscopic partial nephrectomy (LPN). Methods This prospective, randomized, controlled study was conducted from August 2017 to November 2018 at Peking Union Medical College Hospital (Beijing, China).

Ultrasound-guided Selective Cervical Nerve Root Block Plus Superficial Cervical Plexus Block for Minimally Invasive Parathyroidectomy.

Objective To explore the efficacy and safety of ultrasound-guided cervical root block (CRB) in patients undergoing minimally invasive parathyroidectomy (MIP).Methods We enrolled 35 patients with hyperparathyroidism undergoing MIP in Peking Union Medical College Hospital.C4-7 nerve roots were identified in ultrasound imaging by the shape of the transverse process.

Low-dose Simvastatin Increases Skeletal Muscle Sensitivity to Caffeine and Halothane.

Objective To determine whether the myotoxic side effects of statin simvastatin affect skeletal muscle's sensitivity to caffeine and halothane.Methods Primary cultured neonate rat skeletal myotubes were treated with 0.01-5.

Ultrasound-guided Transversus Abdominis Plane Block Improves Postoperative Analgesia and Early Recovery in Patients Undergoing Retroperitoneoscopic Urologic Surgeries: A Randomized Controlled Double-blinded Trial.

Objective To evaluate the effects of ultrasound-guided transversus abdominis plane (TAP) block on postoperative analgesia and early recovery in patients undergoing retroperitoneoscopic urologic surgeries. Methods This was a randomized, controlled, double-blinded trial. Eligible patients scheduled for retroperitoneoscopic urologic surgeries were randomly assigned to two groups.

Influence of Sex on Remifentanil's Cough-prevention Effect during Anesthetic Emergence.

Objective: To investigate the influence of sex on the cough-preventing effect of target-controlled infusion(TCI)of remifentanil during anesthetic emergence.

Methods: A total of 25 female(group F)and 25 male(group M)patients undergoing thyroidectomy were recruited in the current study. Anesthesia was maintained with sevoflurane and remifentanil TCI.

Clinical features and diagnosis for Chinese cases with malignant hyperthermia: a case cluster from 2005 to 2007.

Background: Malignant hyperthermia (MH), manifesting as MH crisis during and/or after general anesthesia, is a potentially fatal disorder in response to volatile anesthetics and depolarizing muscle relaxants. Though typical features of MH episode can provide clues for clinical diagnosis, MH susceptibility is confirmed by in vitro caffeine-halothane contracture test (CHCT) in western countries. It is traditionally thought that MH has less incidence and fewer typical characteristics in Chinese population than their western counterparts because of the different genetic background.
