Randomized Controlled TrialImpact of non-invasive continuous blood pressure monitoring on maternal hypotension during cesarean delivery: a randomized-controlled study.
This study aimed to investigate the efficacy of the ClearSight™ system (Edwards Lifesciences, Irvine, CA) for reducing the incidence of hypotension compared with the traditional oscillometric blood pressure monitoring in cesarean delivery under spinal anesthesia. ⋯ The accuracy and trending ability of the ClearSight™ system for blood pressure measurement was clinically acceptable in cesarean delivery under spinal anesthesia, leading to reductions in maternal hypotension and nausea.

Randomized Controlled TrialHigh-dose intraoperative remifentanil infusion increases early postoperative analgesic consumption: a prospective, randomized, double-blind controlled study.
The purpose of this study was to determine whether intraoperative infusion of remifentanil induces acute tolerance to opioids, and compare the postoperative pain and opioid consumption by the effect site concentrations of remifentanil. ⋯ Intraoperative infusion of remifentanil with 12 ng/ml of effect site concentration in patients undergoing gastrectomy increases early postoperative fentanyl requirement. Acute opioid tolerance would be developed by higher concentration of remifentanil than dosage of common anesthetic practice.

Randomized Controlled Trial Multicenter StudyThe effect of anesthetic technique on µ-opioid receptor expression and immune cell infiltration in breast cancer.
Clinical histological studies demonstrate that the distribution of natural killer (NK) cells, other immune cells and μ-opioid receptors (MOR) within cancer tissue can predict cancer prognosis. No clinical study has evaluated whether anesthetic technique influences immune cell and MOR expression within human breast cancer. ⋯ General anesthesia with opioid analgesia increased resected tumor MOR expression compared with propofol-paravertebral anesthetic technique, but the anesthetic technique did not significantly influence the expression of immune cell markers.

Randomized Controlled Trial Comparative StudyUltrasound-guided quadratus lumborum block in pediatrics: trans-muscular versus intra-muscular approach.
Quadratus lumborum (QL) block has four approaches. However, there is difference between the four approaches regarding efficacy, safety and adverse effects. The primary objective of this study is to compare the analgesic effect between trans-muscular and intra-muscular approaches of the QL block in pediatric patients for elective lower abdominal surgery. ⋯ TQL is better than IQL in the analgesic efficacy following the pediatric lower laparotomy.
