Abstract
PurposeTonsillectomy under general anesthesia may be viewed preferentially to local anesthesia, due to mitigation of potential airway compromise secondary to intraoperative hemorrhage, patient discomfort and anxiety. However, this is offset by risk of increased trauma (via the endotracheal tube and gag), adverse medication reactions and cost. Here we evaluated the case for use of local anesthesia in tonsillectomy using the BiZact™ (Medtronic) device by comparing surgical outcomes and cost factors across patients where either local or general anesthesia was employed. Materials and methodsRetrospective cohort study of 59 BiZact™ tonsillectomy patients (38 under local anesthetic, and 21 under general anesthetic) from a single surgeon at Tauranga Hospital (public) and Grace Hospital (private) in New Zealand; March 2018 to June 2021. ResultsNeither patient group had any primary postoperative hemorrhage and there was comparable incidence of secondary hemorrhage (one case in each cohort). Local anesthetic tonsillectomy was well tolerated with only 2 patients requiring conversion to general anesthetic secondary to anxiety. Local anesthetic proved to be cost-effective, with a halving of hospital length of stay and significant associated overall cost saving, and did not add significantly to operating or total theatre time. Local anesthetic tonsillectomies where perioperative sedation was not required were associated with additional reductions in recovery and overall hospital stay, and cost. ConclusionsLocal anesthetic BiZact™ tonsillectomy is evidently safe and cost-effective.
