Ruminants can be safely anesthetized in a field setting. The higher level of analgesia provided by anesthesia eliminates the need for local anesthetic blockade, which can prove useful when a procedure is expected to produce a substantial level of pain or local anesthetic blockade is not feasible. Certain aspects of anesthesia place the patient at greater risk than chemical restraint techniques....

background: the basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. in addition, the stethoscope is not applicable for continues monitoring, and it is u...

Pain management after total knee arthroplasty (TKA) remains among the most important challenges for patients with TKA. Intra-articular local anesthetic has been shown to reduce postoperative pain following TKA. However, studies report conflicting results. This meta-analysis evaluated the efficacy and safety of single-dose intra-articular local anesthetics for pain control after TKA. Databases (...

BACKGROUND Prilocaine-lidocaine emulsion (EMLA) has been used successfully as a local anesthetic in patients undergoing superficial procedures. OBJECTIVE The purpose of this study was to investigate the analgesic effect of the patch as a local anesthetic for children undergoing a skin biopsy procedure. The effect on both the pain at the injection site and the pain of the biopsy was investigat...

BACKGROUND The estimated prevalence of lumbar radiculopathy has been described as 9.8 per 1,000 cases of low back pain. There are various surgical and nonsurgical modalities for treating lumbar disc herniation or radicular pain, including epidural injections. Epidural injection administration routes include transforaminal, interlaminar, and caudal approaches. The transforaminal approach require...

Infiltration of a local anesthetic agent (e.g., lidocaine) in the vicinity of the facial nerve can transiently paralyze the temporal branch of the facial nerve and cause ipsilateral brow ptosis. This typically occurs during surgery to remove skin cancers on the temple. The buccal nerve typically is not prone to transient or permanent damage because it lies deep to the buccal fat pad. A case of ...

OBJECTIVES Local anesthetic infiltration is also a process of a painful process itself. INJEX™ technology, known as "Needle-free" drug delivery system, was designed for reducing the pain associated with cutaneous procedures. We conducted a prospective, randomized trial to evaluate the application of lidocaine with INJEX™ system and 27-gauge needle. METHODS A total of 60 consecutive patients w...

BACKGROUND There have been few studies on the effect of an elevated concentration of lidocaine hydrochloride in the surgical removal of an impacted lower third molar. This study aimed to examine the efficacy of 4% lidocaine along with 1:100,000 epinephrine compared to 2% lidocaine along with 1:100,000 epinephrine as inferior alveolar nerve block for the removal of an impacted lower third molar....

We present a standardized method for using four-dimensional ultrasound (4D US) guidance for peripheral nerve blocks. 4D US allows for needle tracking in multiple planes simultaneously and accurate measurement of the local anesthetic volume surrounding the nerve following injection. Additionally, the morphology and proximity of local anesthetic spread around the target nerve is clearly seen with...
