The concept of fetal pain is becoming increasingly relevant due to growing possibilities for invasive intrauterine treatment. There is much debate as to whether the fetus is mature enough to be able to perceive pain at all. Recent studies have suggested that the fetus is at least capable of exhibiting a stress response to intrauterine needling. Intrauterine transfusions are most commonly performed by inserting a needle either in the umbilical cord root at the placental surface, or in the intrahepatic portion of the umbilical vein of the fetus. Recently, intrauterine needling in the intrahepatic vein has been shown to result in alterations in fetal stress hormones, which has been interpreted as a reaction to pain. These changes were not observed in intrauterine needling in the umbilical cord root, or after administration of analgesics to the fetus. The investigators tested the hypothesis that remifentanil provides fetal analgesia, assessed by a reduced fetal stress response. The investigators performed a randomised controlled trial comparing fetal stress response between patients undergoing intrauterine transfusions for alloimmune fetal anemia receiving remifentanil, or placebo.

Perioperative adequate analgesia reduces neuroendocrine stress response and postoperative complications. Because opioids are the most effective parenteral drugs to control pain and stress ...
The aim of this study is to compare the accuracy of the changes in CVI in response to a standardized noxious stimulus during various targeted pseudo-steady-state concentrations of remifent...
The purpose of this study is to determine whether remifentanil use in preeclamptic patients may blunt hemodynamic response to intubation during general anesthesia for cesarean section.
Although remifentanil provides profound analgesia during operation, postoperative occurrence of hyperalgesia and tolerance after remifentanil administration could be a challenge to the pos...
High-dose remifentanil infused intraoperative ironically results in postoperative hyperalgesia. Ultra-low dose nalxone is demonstrated to prevent these opioid-induced hyperalgesia in anima...

Patient-controlled analgesia using remifentanil (remifentanil PCA) has been used as a new form of pain relief during labour since soon after its release on the market. Reduction in pain scores lasts f...
Propofol and remifentanil are commonly combined during total intravenous anesthesia. The impact of remifentanil in this relationship is poorly quantified in children. Derivation of an integrated pharm...
Remifentanil-induced hyperalgesia (RIH) is known to be associated with oxidative stress and inflammation. Betulinic acid (BA) was reported to reduce visceral pain owing to its anti-oxidative and anti-...

A genus of HALOBACTERIACEAE distinguished from other genera in the family by the presence of specific derivatives of TGD-2 polar lipids. Haloarcula are found in neutral saline environments such as salt lakes, marine salterns, and saline soils.
A family of gram-negative, moderately halophilic bacteria in the order Oceanospirillales. Members of the family have been isolated from temperate and Antarctic saline lakes, solar salt facilities, saline soils, and marine environments.
A class of traumatic stress disorders that is characterized by the significant dissociative states seen immediately after overwhelming trauma. By definition it cannot last longer than 1 month, if it persists, a diagnosis of post-traumatic stress disorder (STRESS DISORDERS, POST-TRAUMATIC) is more appropriate.
A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and lipid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi).
Stress wherein emotional factors predominate.
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
Pain is defined by the International Association for the Study of Pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”. Some illnesses can be excruci...
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
