OBJECTIVE To describe the ultrasound-guided technique to the transversus abdominis plane (TAP) block in the dog and evaluate the spread of a local anesthetic/methylene blue solution. STUDY DESIGN Prospective experimental trial. ANIMALS Ten adult Beagle cadavers weighing 11.1 ± 1.1 kg (mean ± SD). METHODS Transversus abdominis plane (TAP) blocks were(More)
This study aimed to examine the impact of preoperative lumbar plexus blockade on perioperative analgesia and opioid consumption following hip arthroscopy. The records of patients (n = 236) who underwent hip arthroscopy between July 27, 2004 and November 15, 2009 were reviewed (118 patients with preoperative lumbar plexus block and 118 procedure matched(More)
OBJECTIVE To determine if the volume of injected local anesthetic solution affects cranial to caudal spread when performing ultrasound-guided transversus abdominis plane (TAP) blocks in dogs. STUDY DESIGN Prospective experimental study. ANIMALS Adult Beagle cadavers (n = 20) METHODS Bilateral TAP blocks using ultrasound guidance was performed in 20(More)
The aim of this study was to compare perioperative analgesia provided by single-injection adductor canal block (ACB) to continuous femoral nerve catheter (FNC) when used in a multimodal pain protocol for total knee arthroplasty (TKA). A retrospective cohort study compared outcome data for 148 patients receiving a single-injection ACB to 149 patients(More)
Propofol injection pain, despite various strategies, remains common and troublesome. This study aimed to test the hypothesis that pretreatment with the combination of intravenous lidocaine and magnesium would have an additive effect on reducing propofol injection pain. After institutional review board (IRB) approval and informed consent, we performed a(More)
An expanding body of literature exists which describes the airway challenges and management options for lingual tonsillar hypertrophy (LTH). The use of retrograde intubation to secure a patient's airway in the setting of LTH has been previously unreported and should be considered early in the event of a cannot intubate, cannot ventilate scenario. A(More)
BACKGROUND AND OBJECTIVES Obese patients can pose a unique perioperative anesthetic challenge, making regional anesthetic techniques an intriguing means of providing analgesia for this population. Ultrasound guidance has been touted recently as being beneficial for this population in which surface landmarks can become obscured. In this study, the effect of(More)
BACKGROUND Recent manuscripts have described the use of ultrasound imaging to evaluate airway structures. Ultrasound training tools are necessary for practitioners to become proficient at obtaining and interpreting images. Few training tools exist and those that do can often times be expensive and rendered useless with repeated needle passes. METHODS We(More)
This study characterizes the performance and success rate for fiberoptic-guided tracheal tube placement through the air-Q® Intubating Laryngeal Airway (air-Q). Using a manikin, anesthesia trainees and staff anesthesiologists, experienced in fiberoptic-guided intubation, performed five consecutive fiberoptic-guided tracheal tube placements via the air-Q.(More)
The transversus abdominis plane (TAP) block is an innovative regional anesthetic technique using local anesthetic that is gaining popularity in the analgesic management of human patients undergoing abdominal surgery. Needle placement in the TAP block is within the facial plane between the internal oblique and transversus abdominis muscles and involves the(More)
