The most important acute neurological diseases seen at neurosurgery departments are traumatic brain injuries (TBI) and subarachnoid hemorrhages (SAH). In both diseases the pathophysiological sequela are complex and have not been fully understood up to now, and rodent models using rats and mice are most suitable for the investigation of the pathophysiological details. In both models, surgery is performed under anesthesia, followed by assessment of their functional outcome and behavioral testing before brain tissue analysis after euthanasia...

Postoperative analgesia in rodent sepsis models has been considerably neglected in the past. However, intentions to model clinical practice, increasing awareness of animal ethics, efforts to apply the 3Rs (replacement, reduction, refinement), and stricter legislation argue for a change in this respect. In this review, we describe different concepts of analgesia in rodent models of sepsis focusing on opioid agonists as well as non-opioid analgesics. Advantages and pitfalls in study design and side-effects are discussed...

INTRODUCTION: Open chest surgery (thoracotomy) is considered the most painful of surgical procedures. Forceful wound retraction, costochondral dislocation, posterior costovertebral ligament disruption, intercostal nerve trauma and wound movement during respiration combine to produce an acute, severe postoperative pain insult and persistent chronic pain many months after surgery is common. Three recent systematic reviews conclude that unilateral continuous paravertebral blockade (PVB) provides analgesia at least equivalent to thoracic epidural blockade (TEB) in the postoperative period, has a lower failure rate, and symptom relief that lasted months...

OBJECTIVE: We evaluated the analgesic feasibility of paralaminar in-plane (PL) approach for ultrasound-guided thoracic paravertebral block (USG-TPVB). As the needle trajectory was expected to be closely affected by the distance from the skin to the lamina-transverse process junction (LTPJ), we examined the correlativity between them on computed tomography (CT) or ultrasonography. METHODS: Thirty-two patients undergoing thoracotomy were recruited. We measured the distances between the skin and LTPJ using preoperative CT (S-L) and procedural ultrasonography (US-L)...

BACKGROUND: Although hand-assisted laparoscopic surgery (HALS) offers patients smaller surgical incisions, they still experience pain. Currently, there is no consensus on the optimal analgesic package for patients undergoing HALS. The aim of this prospective, randomized, double-blinded, placebo-controlled clinical trial was to evaluate the effect of transversus abdominis plane (TAP) block on postoperative pain control (pain score and analgesic use) and other outcomes in colon cancer patients undergoing hand-assisted laparoscopic left hemicolectomy...

PURPOSE: Intracerebral hemorrhage (IH) and cephalalgia are common consequences of traumatic brain injury. One of the primary obstacles for patient recovery is the paucity of treatments to support an appropriate analgesic protocol. The present study aimed to assess pain and motor behaviors following different doses of fentanyl on a rat model of IH. METHODS: Twenty-one male Sprague Dawley rats underwent a stereotaxic surgery to produce a collagenase-induced IH in the right caudoputamen nucleus...

Glioblastoma (GBM) is one of the most lethal brain cancers worldwide, and there is an urgent need for development of novel therapeutic approaches. Parecoxib is a well-known cyclooxygenase-2 (COX-2) inhibitor, had already been developed for postoperative analgesia with high efficience and low adverse reaction. Recent study suggested that parecoxib potently enhances immunotherapeutic efficacy of GBM, but its effects on GBM growth, migration and invasion had never been studied before. In the present study, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and, BrdU (5-Bromo-2-deoxyUridine) incorporation assays were used to evaluate the cell proliferation of GBM cells...

Opioids are increasingly used in alleviating pain, including cancer-related pain and postoperative pain. Unfortunately, the development of tolerance, the resistance of neuropathic pain on opioid analgesia or other undesirable effects may limit their utility. In order to reduce opioid doses, and thereby to avoid the risk of side effects and sudden deaths due to overdosing, attempts have been made to introduce co-analgesics. Due to an increasing amount of data concerning a potential enhance of opioid analgesia by the physiological antagonist of N-methyl-d-aspartate receptors, magnesium ions (Mg(2+)), a concomitant use of such a combination seems to be interesting from a clinical point of view...

BACKGROUND: The minimal effective analgesic concentration of opioids required for satisfactory analgesia may differ significantly among the patients. Genetic factors may contribute to the variable response to opioids by affecting their pharmacokinetics or pharmacodynamics. METHODS: Ninety nine patients undergoing abdominal surgery with colorectal anastomosis because of colorectal carcinoma were enrolled in the present study. C34535T was genotyped in all subjects and the patients were divided into three groups according to their genotype: CC-wild type homozygous, CT-mutant heterozygous and TT-mutant homozygous...
