Clinical TrialA Cadaveric Study of Ultrasound-Guided Maxillary Nerve Block Via the Pterygopalatine Fossa: A Novel Technique Using the Lateral Pterygoid Plate Approach.
This study aimed to describe and assess the accuracy and feasibility of a novel technique for ultrasound-guided maxillary nerve block using the lateral pterygoid plate (LPP) approach via the pterygopalatine fossa (PPF) in a soft cadaveric model. ⋯ This cadaveric study suggests that ultrasound-guided maxillary nerve block using the LPP approach via the PPF has a high degree of accuracy and feasibility. Further studies are required to confirm its efficacy and safety for clinical application.

Case ReportsMajor Laparoscopic Intraperitoneal Surgery Performed With Combined Bilateral Subcostal Transversus Abdominal Plane Block and Celiac Plexus Block, Intravenous Sedation Without Tracheal Intubation: A Feasibility Study of 3 Cases.
Major abdominal surgery usually requires general anesthesia with tracheal intubation and may be supplemented with neuraxial anesthesia to provide intraoperative and postoperative pain relief. Attempts at using only neuraxial anesthesia for major abdominal surgery have often been shown to be poorly effective. This report demonstrates that laparoscopic colonic surgical procedures can be performed with ultrasound-guided blocks (bilateral transversus abdominal plane block and celiac plexus block) and intravenous sedation, while avoiding general or neuraxial anesthesia. ⋯ To date, celiac plexus block has been used almost exclusively to relieve pancreatic cancer pain. This is the first report in which it is shown that major intra-abdominal surgery can be performed almost exclusively with regional anesthesia while avoiding adverse effects and problems associated with either general or neuraxial anesthesia. In addition, prolonged postoperative pain relief facilitated early recovery.

Randomized Controlled Trial Multicenter StudyPectoral I Block Does Not Improve Postoperative Analgesia After Breast Cancer Surgery: A Randomized, Double-Blind, Dual-Centered Controlled Trial.
General anesthesia for breast surgery may be supplemented by using a regional anesthetic technique. We evaluated the efficacy of the first pectoral nerve block (Pecs I) in treating postoperative pain after breast cancer surgery. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT01670448.

Randomized Controlled TrialPostoperative Analgesic Effect of Ultrasound-Guided Intermediate Cervical Plexus Block on Unipolar Sternocleidomastoid Release With Myectomy in Pediatric Patients With Congenital Muscular Torticollis: A Prospective, Randomized Controlled Trial.
Unipolar sternocleidomastoid release with myectomy (USRM) for correction of congenital muscular torticollis in pediatric patients produces moderate to severe postoperative pain. The objective of this trial was to examine the effect of ultrasound-guided intermediate cervical plexus block on postoperative pain after USRM. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT02651311.

Randomized Controlled Trial Comparative StudyPerineural Low-Dose Dexamethasone Prolongs Interscalene Block Analgesia With Bupivacaine Compared With Systemic Dexamethasone: A Randomized Trial.
Perineural dexamethasone and intravenous (IV) dexamethasone have been shown to prolong peripheral nerve block duration. The effects of perineural and IV dexamethasone have only been compared at doses of 4 mg or greater. This triple-blind, randomized trial examined the effect of 1 mg IV versus perineural dexamethasone on interscalene block (ISB) analgesia duration. ⋯ This study was registered at Clinicaltrials.gov, identifier NCT02506660.
