Filter by:The purpose of this study is to determine whether liposomal bupivacaine (long acting injectable anesthetic) provides greater post operative pain relief compared to the standard post operative pain regiment for tonsillectomy patients.
The purpose of this study is to evaluate outcomes of popliteal nerve blocks for postoperative pain control in patients undergoing ankle and hindfoot reconstruction surgeries. The following outcomes will be analyzed: length of hospital stay, level of pain control, pain medication use, complications, and patient satisfaction.
Intubation is a procedure that requires well relaxed muscles while general anesthesia is performed. In order to get adequate muscle relaxation, remifentanil, sevoflurane or both agents in combination have been reported as they can provide adequate conditions for laryngoscopy and tracheal intubation without using muscle relaxants. However, there were no previous studies to find the effective dose of sevoflurane in combination with different bolus doses of remifentanil to obtain adequate endotracheal intubation conditions without using muscle relaxants. The aim of this study is to investigate the change in the minimum sevoflurane alveolar concentration which produces an adequate endotracheal intubation condition when sevoflurane is combined with different bolus doses of remifentanil used in clinical practice.
Background: Millions of pediatric patients undergo laparoscopic surgeries every year and many of them suffer significant pain and anxiety. Patient's anxiety correlates with the severity of pain and effective postoperative analgesia is necessary for optimal recovery. Single injections ultrasound guided rectus sheath blocks provide satisfactory postoperative analgesia after pediatric laparoscopic appendectomy, however they are short lived. Searching for a blocking agent that last long enough to outlast pain and has minimal side effects is a difficult task. Using a combination of drugs yielded mixed results. Few pediatric studies showed at best a weak trend in favor of clonidine prolonging analgesia after some blocks, but anxiolytic properties of clonidine were not investigated. This study will compare rectus sheath ropivacaine blocks with ropivacaine and clonidine blocks. Methods: One hundred pediatric patients (10-17 years old) scheduled for laparoscopic appendectomy will be double blinded and randomized to the two treatment groups: the Ropivacaine Group will receive ropivacaine 0.5% (10 ml) injected bilaterally in the posterior rectus sheath, at the umbilicus location, and Ropivacaine Clonidine Group will receive ropivacaine 0.5% (10 ml) and clonidine (2mcg/kg). Post-operative analgesia will be provided with ketorolac and acetaminophen around the clock, and morphine, or/and oxycodone as needed. The primary aim is to determine if ropivacaine combined with clonidine prolongs duration of paresthesia. The secondary aims are to determine if the use of clonidine decreases anxiety level, prolongs duration of analgesia, and decreases pain severity at umbilicus laparoscopic site, reduces the need for analgesics, improves satisfaction with pain control, and is associated with complications such as oversedation, hypotension, and bradycardia. Conclusions: Every hour of excellent analgesia count and a prolongation of block duration by at least 50% is clinical relevant. The investigators hypothesize that rectus sheath injections with ropivacaine and clonidine offer improved pain management compared to ropivacaine alone.
This randomized phase IV trial studies how well the continuous infusion of ropivacaine hydrochloride works in reducing pain after surgery in patients with bladder cancer. Ropivacaine hydrochloride is an anesthetic drug used to decrease pain by numbing an area of the body without putting the patient to sleep. Continuous infusion of ropivacaine hydrochloride may reduce pain and improve the quality of life for patients after bladder surgery.
The current study investigated the effect of adding dexmedetomidine to intrathecal morphine for postoperative analgesia in cancer patients undergoing major abdominal surgery.
The aim of this research is to compare the clinical outcome of amalgam restorations placed in conjunction with three different lining protocols, each of which represents a different therapeutic concept.
In this factorial design study, 280 participants having outpatient, arthroscopic shoulder surgery will be randomized into 4 equal sized groups. All participants will receive a standardized interscalene brachial plexus block and 4mg or 8mg of dexamethasone given by the intravenous or perineural (by the nerve with the nerve block) route just prior to their surgery. The purpose of this study is to determine which dose and route of dexamethasone provides the longest duration of pain control and the fewest side effects after surgery. The investigators hypothesize that giving dexamethasone by the perineural route, and by higher doses, will result in the longer durations of pain control, without increased side effects.
Liposomal bupivacaine is a novel local anesthetic designed for prolonged pain relief. Despite its long-acting analgesic potential, liposomal bupivacaine is significantly more expensive than other local anesthetic alternatives. The primary aim of this investigation is to examine whether or not liposomal bupivacaine provides superior pain relief or clinically significant opioid-sparing effects versus a control to justify its cost.
The purpose of this study is to test whether a dose of paracetamol given before surgical incision is more effective at reducing postoperative pain and analgesic consumption in cervical spine surgery versus a dose given at the end of surgery.
