Detection of Cerebrospinal Fluid Leaks Using the Endoscopic Fluorescein Test in the Postoperative Period following Pituitary and Ventral Skull Base Surgery.

Objective Diagnosis of cerebrospinal fluid (CSF) leaks is sometimes challenging in the postoperative period following pituitary and ventral skull base surgery. Intrathecal fluorescein (ITF) may be useful in this setting. Design Retrospective chart review. Setting Tertiary care center. Methods and Participants All patients who underwent pituitary and ventral skull base surgery performed by a single rhinologist between January 2017 and March 2020 were included. There were 103 patients identified. Eighteen patients received 20 ITF injections due to clinical suspicion for CSF leak during the postoperative period without florid CSF rhinorrhea on clinical exam. Computed tomography scans with new or increasing intracranial air and intraoperative findings were used to confirm CSF leaks. Clinical courses were reviewed for at least 6 months after initial concern for leak as the final determinate of CSF leak. Main Outcome Measures Specificity and safety of ITF. Results Eleven (61%) ITF patients were female and 7 (39%) were male. Average patient age was 52.50 ± 11.89. There were six patients with confirmed postoperative CSF leaks, 3 of whom had evaluations with ITF. ITF use resulted in 2 true positives, 1 false negative, 17 true negatives, and 0 false positives. ITF sensitivity was 67%, specificity was 100%, and positive and negative predictive values were 100 and 94.4%, respectively. There were no adverse effects from ITF use. Conclusions Existing modalities for detecting postoperative CSF leaks suffer from suboptimal sensitivity and specificity, delayed result reporting, or limited availability. ITF represents a specific and safe test with potential utility in the postoperative setting.

Cochlear Implantation Under Local Anesthesia With Conscious Sedation in the Elderly: First 100 Cases.

OBJECTIVE: To report the outcomes on a large series of elderly patients who underwent cochlear implantation (CI) surgery under local anesthesia with conscious sedation (LA-CS). METHODS: Retrospective chart review on 100 consecutive elderly patients (> 65 years) who underwent CI with LA-CS at a tertiary care center between August 2013 and January 2020. An age-matched control group of 50 patients who underwent CI with general anesthesia (GA) are used for comparison. Outcomes measured included time in the operating room, time in the postanesthesia care unit (PACU), and rate of adverse events. RESULTS: Cochlear implant surgery under LA-CS was successfully performed in 99 (99%) patients. One patient requiring conversion to GA intraoperatively. No patients in the LA-CS group experienced cardiopulmonary adverse events; however, three patients (6%) in the GA group experienced minor events including atrial fibrillation and/or demand ischemia. Overnight observation in the hospital due to postoperative medical concerns or prolonged wake-up from anesthesia was required in one patient (1%) from the LA-CS cohort and 12 patients (24%) from the GA cohort. Perioperative adverse events exclusive to the LA-CS group included severe intraoperative vertigo (8%), temporary facial nerve paresis (3%), and wound infection (1%). The average amount of time spent in the operating room was 37 minutes less for procedures performed under LA-CS compared to GA (P < .05). The average amount of time in recovery was similar for both groups (P > .05). CONCLUSION: Cochlear implant surgery under LA-CS offers many benefits and is a safe, feasible, and cost-effective alternative to GA when performed by experienced CI surgeons.

Early Outcomes From Early Tracheostomy for Patients With COVID-19.

Importance: Decision-making in the timing of tracheostomy in patients with coronavirus disease 2019 (COVID-19) has centered on the intersection of long-standing debates on the benefits of early vs late tracheostomy, assumptions about timelines of infectivity of the novel coronavirus, and concern over risk to surgeons performing tracheostomy. Multiple consensus guidelines recommend avoiding or delaying tracheostomy, without evidence to indicate anticipated improvement in outcomes as a result. Objective: To assess outcomes from early tracheostomy in the airway management of patients with COVID-19 requiring mechanical ventilation. Design, Setting, and Participants: A retrospective medical record review was completed of 148 patients with reverse transcriptase-polymerase chain reaction-confirmed COVID-19 requiring mechanical ventilation at a single tertiary-care medical center in New York City from March 1 to May 7, 2020. Interventions: Open or percutaneous tracheostomy. Main Outcomes and Measures: The primary outcomes were time from symptom onset to (1) endotracheal intubation, (2) tracheostomy; time from endotracheal intubation to tracheostomy; time from tracheostomy to (1) tracheostomy tube downsizing, (2) decannulation; total time on mechanical ventilation; and total length of stay. Results: Participants included 148 patients, 120 men and 28 women, with an overall mean (SD) age of 58.1 (15.8) years. Mean (SD; median) time from symptom onset to intubation was 10.57 (6.58; 9) days; from symptom onset to tracheostomy, 22.76 (8.84; 21) days; and from endotracheal intubation to tracheostomy, 12.23 (6.82; 12) days. The mean (SD; median) time to discontinuation of mechanical ventilation was 33.49 (18.82; 27) days; from tracheostomy to first downsize, 23.02 (13.76; 19) days; and from tracheostomy to decannulation, 30.16 (16.00; 26) days. The mean (SD; median) length of stay for all patients was 51.29 (23.66; 45) days. Timing of tracheostomy was significantly associated with length of stay: median length of stay was 40 days in those who underwent early tracheostomy (within 10 days of endotracheal intubation) and 49 days in those who underwent late tracheostomy (median difference, -8; 95% CI, -15 to -1). In a competing risks model with death as the competing risk, the late tracheostomy group was 16% less likely to discontinue mechanical ventilation (hazard ratio, 0.84; 95% CI, 0.55 to 1.28). Conclusions and Relevance: This cohort study from the first 2 months of the pandemic in New York City provides an opportunity to reconsider guidelines for tracheostomy for patients with COVID-19. Findings demonstrated noninferiority of early tracheostomy and challenges recommendations to categorically delay or avoid tracheostomy in this patient population. When aligned with emerging evidence about the timeline of infectivity of the novel coronavirus, this approach may optimize outcomes from tracheostomy while keeping clinicians safe.
