Filter by:The erector spinae plane block is a novel regional anesthetic technique that allows for analgesia of the thorax and abdomen with a peripheral nerve block. This study is being performed to assess the effectiveness of this technique in reducing post-operative pain scores and opiate requirements in pediatric and adult patients undergoing rib cartilage grafting surgeries.
Propofol with remifentanil provides good operative conditions for pediatric cochlear implant (CI); however, large doses of remifentanil usually result in postoperative hyperalgesia and increase postoperative pain. Local anesthesia (LA) is commonly used as an adjunct to general anesthesia in children; however, otologists are usually reluctant in the use of LA as it can cause abolishment of the electrical stapedial reflex threshold (ESRT).
Ophthalmological procedures such as cataract extraction can be carried out with a peribulbar block (PBB). The advantages of this anesthetic technique include a lower incidence of coughing, unwanted movements and emesis during awakening, in addition to providing adequate postoperative analgesia. The researchers want to investigate whether the use of fentanyl citrate by peribulbar route, when administered with a local anesthetic, shortens the anesthetic latency, interfere with the degree of akinesia and if provides greater postoperative analgesia.
Intravenous regional anesthesia is a commonly used technique in the outpatient setting for short hand and upper extremity cases, such as carpal tunnel release or trigger finger release. The technique requires a tourniquet, Esmarch bandage, an intravenous line, and lidocaine. It can be performed and learned easily. The technique is safe and easy to perform, and it provides adequate anesthesia for short cases; however, there are still some cases in which adequate anesthesia is not achieved. One of the possible reasons for failure is that the local anesthetic (lidocaine) does not properly exit the veins to reach the interstitial space (where many nerves are located) to provide the nerve block. In this study, the investigators hypothesize that after application of lidocaine to the intravenous system, application of external pressure through the skin will facilitate tissue penetration and improve the block. The only research procedure being done is a re-application of the Esmarch bandage; all other procedures are Standard of Care.
To find out if dexamethasone used as adjuvant to ropivacaine, a long-lasting local anesthetic, prolongs the duration of modified pectoral nerve block in women undergoing breast surgery.
One of the most frequently performed peripheral nerve blocks (the injection of local anesthetic near nerves to block sensation/ movement to a specific part of the body) is the interscalene brachial plexus block for upper extremity surgeries. This type of block can unmask underlying respiratory issues such as shortness of breath due to a well-known and typically insignificant side effect of temporary diaphragmatic paralysis. The nerve block may be able to use saline solution to wash out the local anesthetic and potentially reverse this respiratory side effect. Specifically, the goal of this study is to determine if the injection of saline through the nerve block catheter reverses blockade of the phrenic nerve supplying the diaphragm, without affecting the ability of the nerve block to provide pain control after surgery.
The purpose of this study is to evaluate if applying a lidocaine topical solution before wounds treatment decreases the pain of the procedure in comparison with placebo solution.
The prevalence of birth canal lacerations is more than 70% of all deliveries in Canada. The repair of such lacerations is usually done using a pre-existing epidural analgesia. Once the analgesic effect of the epidural analgesia fades, the laceration may cause intolerable pain, and result in emotional stress, difficulties in ambulation and breastfeeding, and more. The research team hypothesis is that adding a locally injected analgesic, which will take effect once the epidural analgesia fades, may alleviate perineal pain, prevent such difficulties, and improve women's overall well-being and satisfaction. The proposed trial is a two-arm, single-masked, randomized trial. Women with a working epidural analgesia, and a laceration will be invited to participate. Women in the local anesthesia (LA) arm will get a LA injected to the laceration and women in the sham arm will get no injection. The differences in perineal pain between the groups will be evaluated at 6 hours after last epidural dose.
The aim of this study is to investigate whether it is possible to prolong time to first opioid with the TQL block by inserting catheters bilaterally, providing continuous analgesia, in patients undergoing elective CS. Our hypothesis is that it will be possible to significantly extend time to first opioid with the blockade by 66.6%, increasing it from a mean of 5.6 hours to a mean of 10 hours.
The purpose of the study is to evaluate the efficacy and safety of Zingo in treating pain associated with venipunture and peripheral venous cannulation.
