Filter by:Recently, more distal approach to femoral nerve branches (saphenous) in the adductor canal in the medial compartment of the thigh have shown to provide comparable anesthesia and analgesia without quadriceps muscle weakness than traditional femoral nerve blocks (FNB) after total knee arthroplasty (TKA). Adductor canal block (ACB) has the unique advantage of providing localized analgesia to the peripatellar and intra-articular aspects of the knee joint without reducing the patient's ability to perform a straight leg raise. However, it does not adequately address the incisional pain component on the anterior surface of the knee innervated by anterior femoral cutaneous nerve. This pain may be improved by addition of the anterior femoral block (AFB). Additionally, the ACB does not provide analgesia to the posterior aspect of the knee, which is commonly moderate to severe after surgery. This pain may be decreased by addition of the genicular block, also known as the iPACK block (interspace between the popliteal artery and the capsule of the knee). There is no study that has evaluated the potentially analgesic benefits of the AFB or the iPACK block combined with ACB after TKA. Therefore, the investigators designed this randomized, prospective, and double-blinded study to assess our hypothesis that the addition of the AFB and/or iPACK block to the ACB will improve analgesic effects, decrease pain scores, deceased opioid requirement, and as well as facilitate early recovery and improve patient satisfaction with pain management in patient after TKA.
In this prospective trial, Stage 1-3 patients having mastectomies or isolated lumpectomy with axillary node dissection will be randomly assigned to general anesthesia with opioids combined with a Pecs II block or to general anesthesia with opioids combined with a placebo Pecs II block. Participants will be followed postoperatively during their entire hospital stay to determine the effectiveness of Pecs II block and opioids versus placebo Pecs II block and opioids as postoperative pain treatment.
Adductor canal block is commonly offered to provide pain relief following knee surgery with the hope that they cause less leg weakness than traditionally performed femoral nerve block. Infrequently, adductor canal blocks also result in leg weakness thereby potentially limiting the advantages of the technique. Investigators want to find out the effective dose for a 30% response (volume of local anesthetic which would result in clinically significant weakness of the leg)
The primary objective of this study is to evaluate the safety of N1539 in subjects with acute moderate to severe pain following unilateral bunionectomy.
The investigators believe sufficient spread to all nerves within the adductor canal—and thereby sufficient analgesia—can only be obtained by bolus injections and not by continuous infusions via a catheter. The aim of the study is to investigate whether an adductor canal block performed as repeated intermittent boluses provides superior pain relief to continuous infusion. The investigators hypothesize that adductor canal block performed as intermittent boluses via a catheter will reduce morphine consumption and pain as well as enhance ambulation and muscle strength compared with continuous infusion.
Postoperative pain can pose significant challenges in the postoperative recovery of patients undergoing major colorectal surgery. Traditionally, opioids have played an important role in treating postoperative pain. It is well established that opioids are highly effective in relieving pain; however opioids are associated with numerous side effects that include nausea, vomiting, constipation, ileus, bladder dysfunction, respiratory depression, pruritus, drowsiness, sedation, and allergic reaction. These opioid side effects, which range in severity, can significantly interfere with discharge home following colorectal surgery. Significant interest exists in the use of local anesthetic based regional anesthesia techniques as a means to extend the analgesic window for patients undergoing colorectal surgery. Specifically, the use of the transversus abdominis plane (TAP) block as an adjunct in postoperative pain control has been widely reported in the anesthesia and colorectal surgery literature. Historically, the block was performed in a blind fashion with relative success and presently the block is typically performed either with ultrasound guidance or laparoscopic visualization. While TAP block has shown to be effective in post-operative pain control, the techniques used to place the block have not formally been compared. The investigators are purposing a prospective, patient-blinded, randomized study of patients undergoing major colorectal surgery to compare TAP block under ultrasound guidance versus laparoscopic visualization versus no TAP block. The investigators hypothesize that laparoscopic-guided TAP block is non-inferior to ultrasound-guided TAP block with respect to perioperative pain control and either technique is superior to no TAP. In addition the investigators will measure procedural time, any adverse events related to the block, overall postoperative analgesic requirement, analgesic duration, postoperative pain scores, length of postoperative hospital stay, incidence of postoperative ileus, and overall patient satisfaction between the three groups.
Evaluation of the efficacy of preemptive versus postoperative administration of etoricoxib in total knee arthroplasty (TKA).
Pain assessment in infants and toddlers is quite challenging since children in these populations are nonverbal or preverbal and cannot describe the presence and severity of pain that they perceive. Over the last decade, advances in the field have included the development of behavioral scoring systems for the assessment of acute pain . However, although they have been validated, these commonly used methods of pain assessment are largely subjective and rely on a highly trained observer. An objective continuous measure of pain would be an important addition to standard behavioral painscores which require nurses to monitor the child's behavioral responses.
This study is researching managing postsurgical pain by injecting both short-acting local anesthetics and EXPAREL® at the time of surgery and reviewing if it could reduce or eliminate the need for postsurgical opioids and improve clinical outcomes following the FAST dental implant surgery procedure. This approach is being compared to the current standard of care.
