Filter by:Because of the insufficiency of cadaveric organs and increasing need for organs, the interest in living donor liver transplantation have been greatly increased. The relative reduction of the remaining liver after the operation in Living Liver Donors makes it difficult and compelling to choose a very effective and very safe method in the management of postoperative analgesia. Opioids are the main agents used in the postoperative analgesia of Live Liver Donors. Opioids have serious side effects such as respiratory depression, apnea, circulatory collapse, coma, and death. Both short-term and long-term administration of opioids cause acute opioid-induced hyperalgesia. Ketamine, an NMDA receptor antagonist, has been hypothesized to counter opioid tolerance and NMDA receptor-mediated central sensitization. Various studies and systematic reviews have shown that low-dose ketamine has an opioid-sparing effect in all surgical patients. Although low-dose ketamine has been shown to be beneficial overall in relieving pain, it is unclear whether it has an identified benefit in hepatectomy cases. The aim of this clinical trial was to evaluate the effect of low-dose ketamine administration on postoperative analgesia in living donor liver donors undergoing right hepatectomy procedure.
Shoulder surgery is the second orthopedic operation cause post operative pain Interscalene block is the standard block for shoulder surgery but it cause phrenic nerve block and diaphragmatic hemipareses Iso block is the block used to block the brachial plexuses cord and suprascapular nerve And paracoracoid subscapularis block supra scapular nerve in supra scapular fosa and axillary nerve as it curves around humeral head
Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) occur in 11-51% of patients after surgery, and its prevalence increases with age. The occurrence of delirium is associated with increased morbidity and mortality, prolonged hospital stay, worse functional recovery. Orthopedic procedures and specifically joint replacements have been considered as a major risk for development of chronic postsurgical pain (CPSP). Approximately 13-44% of patients will develop CPSP after knee or hip arthOpioid abuseroplasty. CPSP may cause the discomfort, distress, disability and opioid abuse. Mounting evidence has revealed that inflammation triggered by surgical trauma plays a key role in POD, POCD and CPSP. Recent studies found that vagus nerve stimulation showed the suppression of inflammation. In this study, the effect of perioperative transauricular vagus nerve stimulation on the prognosis of patients undergoing arthroplasty will be investigated, providing potential solutions for the prevention and treatment of postoperative cognitive dysfunction, postoperative delirium and chronic postsurgical pain.
Total knee replacement is one of the most painful orthopedic surgical procedures. Patients who undergo total knee replacement are usually older and have limited cardiac and pulmonary reserves. The increased sensitivity of elderly patients to drugs makes it necessary to choose postoperative analgesia agents and methods that have minimal side effects. Intrathecal injection of morphine to provide postoperative analgesia during the initial 24-h after the operation is a widely used technique, however, opioid therapy is limited because of the side effects (hypotension, pruritus, nausea, urinary retention, respiratory depression) and intolerance. Alpha-2 adrenergic agonists (clonidine and dexmedetomidine) have pharmacologic characteristics (sedation, hypnosis, anxiolysis, sympatholytic, and analgesia) that make them suitable as adjuvants to multimodal analgesia. Their anti-nociceptive effect is attributed to the stimulation of a2- adrenoceptors located in the central nervous system. The rationale for combining analgesics that produce similar therapeutic effects or synergistic interactions is to accentuate the analgesic efficacy and decrease the side effects by permitting dose reduction of each agent. Human studies on the antinociceptive effects of co-administrated intrathecal morphine (ITM) and dexmedetomidine in postoperative pain are still few. On the other hand, Abdel-Ghaffar et al., results do not support improved analgesia with the combination of intrathecal morphine and dexmedetomidine, despite the absence of significant adverse effects. We hypothesized that the addition of dexmedetomidine to ITM would improve the quality of perioperative pain control and decrease the side effects of postoperative systemic opioid use.
comparing between three different volumes; 15, 20 & 25 ml of 0.25% bupivacaine to determine the best volume of Infiltration Between Popliteal Artery and Capsule of Knee (IPACK) block following adductor canal block (ACB) with the best analgesia and least complications after total knee arthroplasty (TKA)
Through this quantitative, multivariate factorial experimental research of the Parallel Randomized Clinical Trial type, the investigators will try to analyze the effectiveness in reducing levels of anxiety, stress and pain through pre-anesthetic assessment and pain neuroscience education in patients undergoing elective total abdominal hysterectomy.
Dexamethasone will be used as an adjunct to local anesthetics (bupivacaine) to prolong the duration of laparoscopically-placed transversus-abdominis plane blocks in elective colorectal resection.
Various newer techniques have been proposed to enhance analgesia in upper abdominal region. The subcostal transverse abdominis plane (SCTAP) block is the deposition of local anesthetic in the transverse abdominis plane inferior and parallel to the costal margin. There is a growing consensus that the SCTAP block provides better analgesia for upper abdominal incisions than the traditional transverse abdominis plane block. The External oblique intercostal plane (EOIP) block is a novel technique reported by Hamilton et al. performed EOPB by administering LA superior or deep of the external oblique muscle from the sixth intercostal space leading to the blockage of thoracoabdominal nerves at T6-T10. It has several attractive aspects such as easy sono-anatomy ribs one strip of muscle so easy to demonstrate even in obese patients, there is a bony backstop, easy expandable fascial plane that can accommodate a catheter and it is shallow block with no big vessels nearby.
Numerous studies in recent years have shown that the use of opioid-free analgesia can reduce opioid use and length of stay in the recovery room, as published in the journals Anesthesia & Analgesia1. Compared with traditional opioid analgesic anesthesia, opioid-free analgesic anesthesia can be used to reduce postoperative respiratory complications, postoperative nausea and vomiting, and postoperative opioid needs. During surgery, opioid analgesics may have immunosuppressive effects, but different anesthesia/analgesia methods will change the individual's stress response, affect the human body's cellular immunity, and may even lead to changes in angiogenesis growth factors associated with cancer recurrence, so it is likely to affect the prognosis of cancer patients. In addition, Dexmedetomidine, a highly selective alpha-2 adrenergic receptor agonist, can replace opioids for pain relief during surgery, providing superior analgesia and reducing opioid use while reducing the need for general anesthetics amount, thus avoiding suppression of immune system function. A study in the Journal of Anaesthesiology Clinical Pharmacology pointed out that Dexmedetomidine can be used to replace opioid analgesics in surgical anesthesia, and there was no difference in the use of rescue opioid analgesics during and after surgery5. Several clinical studies have shown that opioid-free anesthesia is significantly associated with a lower incidence of respiratory complications and postoperative nausea and vomiting. Therefore, general anesthesia combined with Dexmedetomidine can be regarded as an opioid-free anesthesia strategy.
Laparoscopic surgery is commonly used procedure in diagnostic and treatment including Hysterectomy. Post laparoscopic shoulder pain is common side effect mostly occur after surgery. Postoperative Trendelenburg position might decrease pain by reducing the mechanical pressure of CO2 on the diaphragm. Maintaining the patient in Trendelenburg for 6 hours postoperatively will decrease postoperative shoulder pain.
