Filter by:The pectoralis block, including pecs I and II block, is a novel technique first described in 2011 as an alternative to paravertebral blockade for analgesia following breast surgery. The research goal is to determine the efficacy of the pectoralis block compared to placebo in improving quality of recovery following mastectomy.
The purpose of this study is to investigate and describe the anatomical differences in distribution of the blocked area following a perineural LFCN (Lateral Femoris Cutaneous Nerve) block with either 8 ml or 16 ml of Ropivacaine, in relation to incision lines used in THA (Total Hip Arthroplasty). Furthermore, we examine any loss of motor function in Musculus Quadriceps due to posible involvement of the Femoral Nerve. This trial will be conducted in healthy volunteers, as a blinded, randomized, paired trial.
The TTP block is a novel regional anesthetic technique that shows promise in providing analgesia for anterior chest wall incisions and median sternotomy. The investigators hope to show that by providing the TTP block, there will be reduced early postoperative pain, reduced sedation and shallow breathing, reduced time on breathing machine, leading to an increase in patient comfort and satisfaction. The investigators also hope the decreased need for pain medication and reduced time on the breathing machine will translate into decreased nursing workload.
The purpose of this study is to determine which technique for catheter placement in continuous femoral nerve block (FNB) is most successful - guidance with (1) ultrasound or (2) nerve stimulation and ultrasound. Sensory and motor assessment scores will be obtained post-FNB. Patient controlled analgesia and opiate consumption is also recorded along with pain scores for the first 48 hour post-FNB.
Post-operative analgesia efficacy using ultrasound-guided transmuscular quadratus lumborum block versus ultrasound-guided quadratus lumborum type II block
This is a randomized, double-blinded pilot study to determine whether patients undergoing ambulatory total knee arthroplasty (TKA) using a subvastus approach benefit from the addition of a continuous adductor canal nerve block (cACB) catheter along with an existing multimodal approach to postoperative analgesia. Outcomes include the 15-item Quality of Recovery Scale (QoR-15) (Miles 2016), pain scores, opioid consumption, opioid-free days, functional outcome as measured by the Time Up and Go (TUG) test, patient satisfaction, patient's rating of catheter effectiveness, and complications.
Open inguinal herniorrhaphy is a common outpatient surgical procedure. Post-operative pain can be a significant hindrance to discharge from the post anesthesia care unit. Pain can be treated with opioid therapy, but the literature supports that these agents are known to create or exacerbate adverse effects and complications, including post-operative nausea and vomiting, hypoxia, and urinary retention. In contrast, analgesia provided by regional anesthesia results in a decreased risk of the aforementioned complications.1 Because of this, various regional anesthetic techniques have been developed to provide analgesia following open herniorrhaphy. One technique is a combined ilioinguinal and iliohypogastric nerve block (IINB), which has been shown to decrease the initial pain after inguinal herniorrhaphy.2 The quadratus lumborum block (QLB) is a newer regional anesthetic technique that we think could be as effective as IINB at providing pain control following open herniorrhaphy. Additionally, because local anesthetic injected during a QLB has the potential to spread cranially into the thoracic paravertebral space following its lumbar deposition it could lead to alleviation of both somatic and visceral pain.3 This might therefore improve the quality and or duration of analgesia as compared to the IINB. To the best of the author's knowledge there has been no investigation comparing the efficacy, with regards to post-operative pain management, between IINB and QLB.
The purpose of this study is to determine if there is a difference in patient outcomes with general anesthesia versus spinal anesthesia when given in addition to popliteal and adductor canal nerve blocks for foot and ankle surgery. Popliteal and adductor canal nerve blocks are injections of local anesthetic agents near nerves in the back and front of the knee going to the foot and ankle that provide numbness during and after surgery. These peripheral nerve blocks offer good pain control and reduce the need for opioids (opioids are pain medications such as morphine, Dilaudid, and oxycodone). General anesthesia involves the flow of oxygen and anesthesia gas through a tube which, along with additional intravenous medications, causes unconsciousness and unawareness of sensations during surgery. Spinal anesthesia involves an injection of local anesthetic in the lower back, which causes numbness below the waist. In addition to spinal anesthesia, a sedative is typically given intravenously to cause relaxation and sleepiness throughout surgery. General, spinal, and nerve block anesthesia are all routinely used for surgery at the Hospital for Special Surgery. General or spinal anesthesia is typically used in addition to peripheral nerve blocks during foot and ankle surgery to 1) allow the surgeons to use a thigh tourniquet to reduce bleeding, 2) provide anesthesia earlier, and 3) prevent unwanted movement. However, it is unclear whether general or spinal anesthesia provides better patient outcomes when given with peripheral nerve blocks. Some reports show that on its own, spinal anesthesia has advantages over general anesthesia in terms of side effects such as nausea and pain. However, these advantages may also be gained from combining peripheral nerve blocks with general anesthesia. Spinal anesthesia can be associated with headache and backache, although headache and backache can also happen after operations performed with general anesthesia. A previous study at the Hospital for Special Surgery showed low rates of nausea among patients who received nerve blocks with spinal anesthesia, and no nausea among patients who received a nerve block with general anesthesia. Therefore, the primary aim of this study is to determine if, as a treatment, either general or spinal anesthesia has advantages over the other treatment in terms of readiness for discharge, side effects, pain and patient satisfaction in an ambulatory foot and ankle population.
The purpose of this study is to investigate and describe the anatomical distribution of the sensory outcome following LFCN block (LFCN = lateral femoral cutaneous nerve) in relation to the incisional lines after Total Hip Arthroplasty (THA). Furthermore, is the aim to examine whether there is a motorial outcome corresponding to the Femoral nerve. The trial will be conducted in healthy volunteers in a blinded, randomized paired study.
Patients presenting with subacute, less than 6 months of evolution, adhesive capsulitis are randomly attributed to the control or study group. Both groups receive a series of 3 suprascapular nerve blocks under ultrasound guidance with either 5ml saline or 5ml ropivacaine 2mg/ml ( ref) at 1 week interval. Testing consists of glenohumeral range of motion (ROM) (anterior elevation, lateral elevation, external and internal rotation) measured by goniometer, Constant score and visual analog scale (VAS) pain score. Evaluations are done immediately before and one hour after every suprascapular block and at 4 weeks after the third suprascapular block. All suprascapular nerve blocks are performed by one physician and the evaluations are done by a occupational therapist or MD experienced in glenohumeral function evaluations. All practitioners are blinded to the assigned group. All patients continue their pre-study treatment of physiotherapy and per os pain medication. Patients keep a record of analgesics and NSAID use during the trial. Drop-out rate is measured.
