NCT ID: NCT03310047 Completed - Clinical trials for Anesthesia, Regional

Intra-individual Reproducibility in Nerve Block Duration

Start date: October 30, 2017
Phase: Phase 1
Study type: Interventional

An interventional randomized controlled crossover trial, to illuminate if durations in nerve block durations are predictable within the same subject.

NCT ID: NCT03040167 Completed - Pain, Postoperative Clinical Trials

The Pectoral Block for Breast Augmentation Surgery

BPCAM
Start date: October 1, 2017
Phase: Phase 4
Study type: Interventional

The pectoral block is a recently developed regional anesthetic technique that can be used for the treatment of postoperative pain after breast surgery. Injection of local anesthetic between the major and the minor pectoral muscles is defined as the pectoral (PEC) 1 block. This block has not been well characterized in terms of its blocking effects on motor and sensitive nerves (medial and lateral pectoral nerves and intercostal nerves). This clinical trial is divided into two sections: a volunteer study and a patient study. For the volunteer study, the aim is to assess the sensory territory affected by injection of local anesthetics through a PEC 1 block and to assess motor function in terms of strength of adduction of the affected limb using a dynamometer. In a prospective, randomized, controlled and double blind study, the aim is to assess the postoperative pain relieving properties of the PEC 1 block in patients undergoing bilateral breast augmentation surgery.

NCT ID: NCT03038425 Completed - Clinical trials for Arthroplasty, Replacement, Knee

Does Continuous Adductor Canal Nerve Block Improve the Quality of Recovery for Outpatient Total Knee Arthroplasty Patients?

Start date: May 2, 2017
Phase: N/A
Study type: Interventional

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.

Adductor Canal Block (ACB) Before and After Primary Total Knee Arthroplasty (TKA)

Start date: October 2016
Phase: Phase 4
Study type: Interventional

Total knee arthroplasty (TKA) is associated with severe postoperative pain. Multimodal analgesia, including peripheral nerve block, is recommended for post-operative pain relief 1. Perineural analgesia offers the advantage of extended pain relief up to 24 hours after surgery2. This is a prospective, randomized control trial designed to compare the analgesic efficacy of the adductor canal block (ACB) performed immediately before or immediately after primary total knee arthroplasty (TKA). The primary objective of this study is to measure pain score associated with knee motion following TKA among patients receiving ACB as part of their analgesic regimen for TKA. Secondary end points include assessment of postoperative ambulation, range of motion, pain at rest, opioid consumption, and patient satisfaction between the two analgesic approaches. The investigators hypothesize that ACB before the surgery will reduce a patient's postoperative pain and improve patient satisfaction. All consecutive patients undergoing primary TKA will be recruited for enrollment in the study. Patients will be for randomized preoperatively to receive either preemptive ABC (PreACB) or postoperative ABC (PostACB). Patients randomized to the PreACB group will receive the block prior to incision. Patients randomized to the PostACB group will receive the block at the end of the surgery. Both techniques are in accordance to the standard of care at our institute. All patients will have the ACB done by a regional anesthesiologist in the regional anesthesia unit, or in the operating room. Patient medical history will be obtained and blocks will be placed per usual protocol. Operative and anesthetic details, including medications given, will be recorded. Pain scores and pain medications given in the PACU will be recorded. Supplementary analgesics will be provided per institutional PACU protocol. Study data will be recorded for up to 72 hours or until patient discharge. A follow-up will occur in 4- 6 weeks at the orthopedic follow-up appointment to evaluate the patient's late pain scores and overall satisfaction. Data will be analyzed both at the conclusion of the study and at several intervals prior to completion of the study.

NCT ID: NCT02879916 Completed - Clinical trials for Anesthesia, Regional

Comparison of an Interscalene Nerve Block With or Without Stellate Ganglion Block for Shoulder Surgery

Start date: October 2011
Phase: Phase 4
Study type: Interventional

This study describes the difference of analgesic effect of levobupivacaine 0.5% administered through an interscalene nerve block with or without a stellate ganglion block. The length of the analgesic effect is our primary outcome parameter. Half of the recruited patients will receive a stellate ganglion block and half of the patients won't.
