Nonoperating room regional anesthesia opportunities and challenges: a minireview

Regional anesthesia has an important role to play outside the operating room since a large number of cases are being performed as office based procedures. The main use of regional anesthesia in nonoperating room settings is to provide pain free patient for smooth and seamless conduction of the procedure thereby increasing the overall turnover of number of office-based procedures. The use of nonoperating room regional anesthesia can be also specified in terms of performing a nerve block, administering local anesthetic via spray, creams and patch, and LA nebulization for topicalization of airway mucosa. The major concern related to LA in remote locations include unfamiliar environment along with nonavailability of adequate equipments and chances of LA systemic toxicity.
