Preoperative versus postoperative ultrasound-guided rectus sheath block for improving pain, sleep quality and cytokine levels in patients with open midline incisions undergoing transabdominal gynecological surgery: a randomized-controlled trial.

Background: Nerve block is usually performed before surgery because it inhibits reflection of the skin incision and reduces the amount of intraoperative anesthetic used. We hypothesized that performing rectus sheath block (RSB) after surgery would result in a longer duration of the analgesic effects and have a subtle influence on sleep time after surgery but that it would not decrease the perioperative cytokine levels of patients undergoing gynecological surgery.

Methods: A randomized, double-blinded, controlled trial was conducted from October 2015 to June 2016.

Effects of ultrasound-guided stellate-ganglion block on sleep and regional cerebral oxygen saturation in patients undergoing breast cancer surgery: a randomized, controlled, double-blinded trial.

Numerous factors could contribute to sleep disturbances in women with breast cancer. We hypothesized that stellate ganglion block (SGB) during surgery would preserve sleep after surgery and increase intraoperative regional cerebral oxygen saturation (rSO) on the blocked side in patients undergoing breast cancer surgery. A randomized, double-blinded, controlled trial was conducted at the First Hospital of China Medical University from January 2016 to September 2016.

Changes in the first postoperative night bispectral index of patients after thyroidectomy with different types of primary anesthetic management: a randomized controlled trial.

Despite major advances in anesthesia management and developments in anesthetic agents, postoperative sleep disturbances remain dissatisfactory for many patients. We hypothesized that propofol might have a subtle influence on sleep after thyroidectomy compared to sevoflurane. A randomized, single-blinded, controlled trial was conducted at the First Hospital of China Medical University from October 2014 to October 2015.

Changes in First Postoperative Night Bispectral Index After Daytime Sedation Induced by Dexmedetomidine or Midazolam Under Regional Anesthesia: A Randomized Controlled Trial.

Background And Objectives: Supplementation of spinal anesthesia with various sedatives is a standard protocol to alleviate patient anxiety associated with the surgical procedure. We hypothesized that, compared with dexmedetomidine, midazolam might have a subtle influence on sleep quality after surgery following elective transurethral prostatic resection (TURP) in elderly male patients.

Methods: A randomized, double-blind, controlled trial was conducted at the First Hospital of China Medical University from July 2014 to January 2015.

Preoperative versus postoperative ultrasound-guided rectus sheath block for improving pain, sleep quality and cytokine levels of patients with open midline incisions undergoing transabdominal gynaecological operation: study protocol for a randomised controlled trial.

Background: Rectus sheath block (RSB) is used for postoperative pain relief in patients undergoing abdominal surgery with midline incision. Preoperative RSB has been shown to be effective, but it has not been compared with postoperative RSB. The aim of the present study is to evaluate postoperative pain, sleep quality and changes in the cytokine levels of patients undergoing gynaecological surgery with RSB performed preoperatively versus postoperatively.

Effects of CO2 Pneumoperitoneum on the Cognitive Function of Patients Undergoing Gynecologic Laparoscopy.

Aim: To evaluate the effects of CO2 pneumoperitoneum during gynecologic laparoscopy on patients' postoperative cognitive function.

Methods: This prospective clinical study included 225 adult female patients with American Society of Anesthesiologists physical status I or II. Patients underwent conventional open surgery (group I, n = 115) or gynecologic laparoscopy using abdominal insufflation with CO2 to an intra-abdominal pressure of 15 mm Hg (group II, n = 110).

[Effect of electroacupuncture on the cognitive function and plasma antibodies against beta-amyloid protein in aged rats with ketamine anesthesia].

Objective: To study the effects of electroacupuncture (EA) on the changes of behavior after ketamine anesthesia, and changes of serum antibodies against beta-amyloid (Abeta) and Abeta protein in the hippocampus of aged rats, thus exploring the effects of EA on the cognitive dysfunction.

Methods: Thirty 14-month old SD rats were randomly divided into 3 groups, i. e.

Ketamine reduces inducible superoxide generation in human neutrophils in vitro by modulating the p38 mitogen-activated protein kinase (MAPK)-mediated pathway.

Many cellular stresses and inflammatory stimuli can activate p38 mitogen-activated protein kinase (MAPK), a serine/threonine kinase in the MAPK family. The different stimuli act via different receptors or signalling pathways to induce phosphorylation of the cytosolic protein p47(phox), one subunit of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. Formyl-methionyl-leucyl-phenylalanine (fMLP) has been shown to induce the p38 MAPK phosphorylation during the respiratory burst in human neutrophils.
