Filter by:PCA morphine have been a common method in providing excellent analgesia for post-operative period. However, the usage of morphine is not without any side effects such as nausea, vomiting, respiratory depression, and over sedation. Many adjunct have been used in combination with morphine to observe the opioid sparing effects at the same time providing good analgesia. Dexmedetomidine is a potent and selective alpha-2 receptor agonist with sedative, anxiolytic, sympatholytic, and analgesic effects. As dexmedetomidine and morphine act via different mechanism, this combination produces synergistic analgesic effects. The objective of our study was to observe the effectiveness in pain relief between two low concentration of dexmedetomidine (2 mcg/ml versus 1 mcg/ml) as an adjunct to PCA morphine 1 mg/ml.
the effectiveness of ultrasound guided erector spinae plane block in patients undergoing thoracic spine sugery
- Abdominal hysterectomy is an open surgical procedure associated with considerable post-operative pain. Narcotics are often required during patient recovery but can result in adverse side effects. Transversus abdominis plane block(TAP block) is a regional anesthetic technique that is found to be effective as post-operative analgesia after total abdominal hysterectomy. Recently, erector spinae plane block(ESP)block is found to be safe, and simple regional anesthetic technique that decrease total opioid consumption in patient undergoing breast, or abdominal surgery. - The aim is to compare the efficacy of bilateral erector spinae plane block, and bilateral transversus abdominis plane block on postoperative analgesia in patients after abdominal hysterectomy under general anesthesia, and their need for opioid. Hypothesis - Null hypothesis (H0): No difference between the analgesic effects of bilateral erector spinae plane block, and bilateral transversus abdominis plane block in patients after abdominal hysterectomy under general anesthesia. - Alternative hypothesis (H1): There are difference between the analgesic effects of bilateral erector spinae plane block, and bilateral transversus abdominis plane block in patients after abdominal hysterectomy under general anesthesia.
The transversus abdominis plane (TAP) block is a regional anesthesia technique where local anesthetic is injected into the neurovascular plane between the transversus abdominis and internal oblique muscles. The TAP block has been shown to provide postoperative analgesia following abdominal surgery.There are many methods to administer local anesthetic into the transversus abdominus plane to provide post-operative analgesia. The more prevalent method is for an anesthesia provider to inject local anesthetic into the plane using ultrasound guidance, before surgery or after the conclusion of surgery. Alternatively, a surgeon can administer the local anesthetic during the operation without additional time or expense using direct laparoscopic visualization. We propose to compare the two methods for non-inferiority, in the context of an established enhanced recovery after surgery (ERAS) program. Non-inferiority being established by no demonstrable difference in post-operative narcotic requirements and equivalent average pain scores.
Sternotomy, the reference approach for heart surgery, may induce profound and intense post-operative pain. One method of analgesia used is patient-controlled intravenous morphine. The analgesic efficacy of continuous wound infiltration at the sternum following heart surgery has been demonstrated. The analgesic catheter placed near the sternotomy wound reduces the consumption of morphine. The aim of this study is to determine whether a bolus of tramadol associated with the continuous administration of levobupivacaine via the wound catheter could potentiate the local anaesthetic effects, thus leading to a decreased consumption of postoperative intravenous morphine, and a decrease in morphine-related side effects.
Paracetamol,a classical analgesic agent,constitutes an essential component of multi-modal analgesia. This medication is generally safe, well tolerated and effective within recommended daily dose.The purpose of the study is to evaluate the efficacy and safety of Paracetamol Injection as adjuvant to morphine-based post-operative analgesia, as well as to explore the reasonable dosage of paracetamol among Chinese population under above-mentioned circumstance.
Comparison of efficacy in management of pain in abdominal surgery between epidural versus wound infusion catheter {catheter placed within the incision site}
Aim of this study is to compare benefits and disadvantages in using continuous infusion of morphine or fentanyl for post operative analgesia.
Following foot and ankle surgery, ultrasound-guided sciatic nerve block (SNB) at the popliteal fossa decreases post-operative pain and opioid consumption. At the popliteal fossa, the sciatic nerve bifurcates to form the Common Peroneal Nerve (CPN) and Tibial Nerve (TN). Studies have shown that when both branches are blocked separately distal to the bifurcation site, block onset time is reduced by 30%. Through clinical observation, the investigators found that onset time is further shortened when ultrasound-guided SNB is performed at the site of bifurcation. This is because the local anesthetic spreads interneurally. The purpose of this study is to compare the block onset time of an ultrasound-guided sciatic nerve block at the site of nerve bifurcation with the blockade of each terminal nerve separately (TN and CPN) distal to sciatic nerve bifurcation.
Patients experience significant postoperative pain following shoulder surgery, Single shot interscalene block is used in ambulatory shoulder surgery for its advantages that include significant reduction in acute pain and analgesic requirements, prolonged time to first analgesic request, decreased incidence of nausea, as well as earlier hospital discharge.The process of nerve block requires several needle passes, with each of them being at risk of causing nerve injury either by direct trauma or intraneural injection even with the use of the ultrasound. These facts raised concerns and several authors stated that maybe the anesthesiologists should be more careful, keep a safe distance from the nerve, and inject the local anesthetics into fascial planes containing the nerve and not attempt to place the needle in close proximity to the nerve. This study is designed to determine the maximal effective distance away from the nerve for the injection to be effective.
