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).

A Survey of Surgical Patient's Perception about Anesthesiologist in a Large Scale Comprehensive Hospital in China.

Objectives This study aim to evaluate patient's perception about anesthesiologists' job roles and investigate their expectations for anesthesia care.Methods We designed a self-administered questionnaire for this cross-sectional survey study and delivered questionnaire forms to adult in-patients who were scheduled for elective surgery before pre-operative anesthetic visit the day before surgery. We collected information of respondents' demographic data, education background, health literacy and previous experience of anesthesia, perception of anesthesiologist's job, the expectation on anesthesia care.

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.

Influence of Anesthetic Brochure on Patient's Information Gain, Preoperative Anxiety, Trust, and Satisfaction.

Objective To assess the impacts of anesthetic brochure on anesthetic information gain, preoperative anxiety, trust to anesthesiologists, and satisfaction to the preanesthesia visit for patients undergoing general anesthesia. Methods Totally 134 patients scheduled for elective thyroid surgery under general anesthesia in Peking Union Medical College Hospital were assigned to two groups using the random number table method, among whom 68 patients received brochure before preoperative visit (brochure group) and 66 patients did not (control group). Questionnaires with items for evaluating patient's information gain, preoperative anxiety and trust were completed after preanesthetic visit.

2:1 multiplexing function in a simple molecular system.

1-[(Anthracen-9-yl)methylene] thiosemicarbazide shows weak fluorescence due to a photo-induced electron transfer (PET) process from the thiosemicarbazide moiety to the excited anthracene. The anthracene emission can be recovered via protonation of the amine as the protonated aminomethylene as an electron-withdrawing group that suppresses the PET process. Similarly, chelation between the ligand and the metal ions can also suppress the PET process and results in a fluorescence enhancement (CHEF).
