Article Abstract
A 48-year-old woman, diagnosed as colon cancer with metastases in the liver, lung, bone and left rectus abdominis, developed refractory left abdominal pain in spite of escalating administration of opioids and nerve block therapy, and intrathecal analgesia was applied. The tip of the catheter was intrathecally placed at the level of the T8 vertebra and pain relief was obtained with a daily dose of bupivacaine 36 mg producing segmental analgesia of the area between the 7th and 10th thoracic segments and preserving sensory and motor functions of the lower limbs. Face scale scores decreased from 5/6 to almost 0 after induction of the intrathecal analgesia. Side effects related to systemic opioids, such as nausea, vomiting and sleepiness, significantly improved and she was able to walk to the toilet. It is suggested that when the site of pain is limited to the truncus, intrathecal analgesia only with local anesthetics can be applied without affecting functions of the lower limbs.

Objectives: After cesarean, optimal analgesia is important for early mobilization, mitigating thromboembolic risks, and mother-infant communication. Our study aims to compare the postoperative analgesic effects of intrathecal morphine (ITM) and Erector Spinae Plane Block (ESPB) in elective cesarean section under spinal anesthesia.
Methods: 82 patients were randomized into ESPB and ITM groups.

Dysregulation of GABAergic inhibition is associated with pathological pain. Consequently, enhancement of GABAergic transmission represents a potential analgesic strategy. However, therapeutic potential of current GABA agonists and modulators is limited by unwanted side effects.

Pain associated with cancer is often the first symptom reported with major repercussions on patient's quality of life. Mechanical compression, release of algogenic substances by the tumor or the complications of oncologic treatment represent the major causes. Nociceptive and neuropathic pain are both induced by different mediators that give rise to a neuroinflammation creating a peripheral and central sensitization responsible of chronic pain.

Despite advances in procedural techniques and equipment, postdural puncture headache (PDPH) remains a serious complication of labour epidural analgesia after accidental dural puncture (ADP). Often considered a temporary inconvenience, PDPH can be debilitating in the short term. It can also be associated with chronic manifestations and serious complications.

Opioids are potent analgesics in clinical pain management but exert variable analgesia in different pain types. Opioid-induced constipation is a common side effect of opioid therapy, and whether opioids induce different gastrointestinal motility inhibitions in different pain types is unknown. In this study, we evaluated the antinociceptive effects and inhibition of upper gastrointestinal transit and colonic bead expulsion of morphine, DAMGO, and Deltorphin in mouse CFA chronic inflammatory pain, SNI chronic neuropathic pain, and carrageenan chronic inflammatory pain models.
