686 Evaluating and Modernising the Management of Nasal Trauma in Emergency ENT Clinic

Aim 1. Optimise and compare management of nasal fractures at a single UK based centre with nationally excepted standards from ENT UK and published literature. 2. To measure the non-attendance (DNA) rate in the emergency ENT clinic for patients with nasal trauma. 3. To assess the ratio of face to face (F2F) appointments to patients listed for a manipulation under anaesthesia MUA. 4. To provide additional insight into the aetiology of nasal trauma Method Retrospective analysis of clinical notes for all nasal traumas reviewed in the ENT emergency clinic at a single centre from 1st July 2019 – 1st March 2020. Parameters investigated included – demographics, days from injury, F2F:MUA, DNA rate and aetiology of injury. Implementation of a video-based clinic and local anaesthetic MUA clinic. Results At total of 255 patients and 311 appointments notes were reviewed in this period. DNA rate was found to be 28%. F2F:MUA was found to be 4:1. Patients were reviewed on average 9 days post-injury. Most common causes of trauma were assault (39%), fall (31%), sport (13%), accidental hit (10%). Conclusions The DNA rate was found to be 20% higher than the national average for outpatient clinics and a F2F:MUA of 4:1 displays a high burden of unnecessary F2F contact. A video-based and local anaesthetic nasal fractures clinic has been implemented to combat these issues which will be re-audited.

Nasal High-Frequency Oscillatory Ventilation vs. Nasal Continuous Positive Airway Pressure as Therapy for Postextubation Respiratory Failure in Infants After Congenital Heart Surgery

Objective: This study aimed to evaluate the effects of nasal high-frequency oscillatory ventilation (NHFOV) vs. nasal continuous positive airway pressure (NCPAP) on postextubation respiratory failure (PRF) in infants after congenital heart surgery (CHS).Method: Eighty infants underwent postoperative invasive mechanical ventilation for more than 12 h and planned extubation. The infants were randomized to undergo either NHFOV or NCPAP after extubation. Primary outcomes were the incidence of PRF and reintubation, the average PaCO2 level, the average oxygenation index (OI), and pulmonary recruitment in the early extubation phase. Secondary outcomes included the NCPAP/NHFOV time, length of hospital stay, treatment intolerance, signs of discomfort, pneumothorax, adverse hemodynamic effects, nasal trauma, and mortality.Results: Except for PaCO2 within 12 after extubation (39.3 ± 5.8 vs. 43.6 ± 7.3 mmHg, p = 0.05), there was no statistically significant difference for any of the primary outcome measure (PRF, reintubation within 12 h after extubation, oxygenation index within 12 h after extubation, or lung volumes on X-ray after extubation) or secondary outcome measures (duration of non-invasive ventilation, duration of hospital stay, ventilation intolerance, signs of discomfort, pneumothorax, nasal trauma, adverse hemodynamic effects, or death prior to discharge), p > 0.1 for each comparison.Conclusion: NHFOV therapy after extubation in infants after CHS was more efficient in improving CO2 cleaning than NCPAP therapy, but there was no difference in other outcomes (PRF, reintubation, oxygenation index, and pulmonary recruitment).

Results of hyperbaric oxygen treatment in an at-risk nasal flap following trauma

Hyperbaric oxygen treatment (HBOT) is widely used in otorhinolaryngology for various purposes. A 20-year-old male patient was admitted following a traumatic nasal wound which occurred several hours prior. He had a nasal glass cut from the radix to the supratip area which was primarily closed by non-absorbable suture. The following day, there was a haematoma and necrosis of the skin. The haematoma was drained under local anaesthesia. Blood supply to the nasal skin was severely compromised and only the columellar artery remaining intact, by definition designating this a difficult to heal wound with the risk of overall healing failure. Necrosis of the skin had developed within the first 24 hours. Accordingly, the patient underwent 30 HBOT sessions (two hours at 253.3 kPa) twice daily for four days and daily thereafter. Antibiotic cover and conservative wound management were also used. Complete healing was achieved without the need for additional surgical intervention. We conclude that timely use of HBOT may be a valuable adjunct to conservative wound management in a case of sharp nasal trauma.

Systematic review of high-flow nasal cannula versus continuous positive airway pressure for primary support in preterm infants

IntroductionWe conducted a meta-analysis of trials that compared efficacy and safety of high-flow nasal cannula (HFNC) with continuous positive airway pressure (CPAP) as primary respiratory support in preterm infants and a study of the impact of clinical relevant parameters.MethodsDatabases were searched for randomised controlled trials comparing HFNC with CPAP as primary respiratory support in preterm infants. Treatment failure was considered as primary outcome and adverse events as secondary outcomes. We calculated risk ratios (RRs) in intention-to-treat analysis and random-effects meta-analyses of risks were conducted.ResultsWe included 10 studies for a total of 1830 patients. Meta-analysis demonstrated an RR of treatment failure multiplied by 1.34 using HFNC compared with CPAP (RR=1.34, 95% CI 1.01 to 1.68, I2=16.2%). Secondary outcome meta-analysis showed no difference in intubation rates (RR=0.90, 95% CI 0.66 to 1.15) and a lower rate of nasal trauma using HFNC compared with CPAP (RR=0.48, 95% CI 0.31 to 0.65, I²=0.0%). Meta-regressions did not show any influence of gestational age and weight at birth, HFNC flow rate, type of CPAP generator or use of surfactant.ConclusionsDespite a higher risk of treatment failure, considering no difference in intubation rates and a lower rate of nasal trauma using HFNC compared with CPAP, we suggest that HFNC should be used as primary respiratory support in preterm infants.

Management and Complications of Nasal Septal Collections

Background: Nasal septum collections (hematoma and abscess) can lead to structural and functional abnormalities. Our objective was to assess the clinical characteristics, management and complications of nasal septal collections, and document factors associated withtheir complications. Methods: This was a retrospective study of patients managed for nasal septal collections. Socio-demographic and clinical information was recorded, and the main investigations and results noted. Follow-up and complications of septal collections were documented and the clinical factors associated with the complications explored. Results: Twenty-four patients records were studied: male: female ratio=2:1, mean age 40.1±13.1years,62.5% presented with complaints of nasal obstruction, 66.7% had antecedent nasal trauma, presentation was from 2 to 13 days,25%had co-morbid disease(s). All patients had incision and drainage of the septal collection within 1–7 h; 41.2% of the aspirated collections cultured microorganisms, 20.8% developed complications. Increased age above 45 years, co-morbidity, delayed presentation, culture-positive aspirate was all significantly associated with development of complications. Conclusion: Nasal septal collections were more common in adult males with antecedent nasal trauma; 20% developedcomplications associated with the presence of culturepositive abscesses, increased age, and duration of septal collection.

Efficacy and Safety of Heated humidified high-flow nasal cannula for Preventing Extubation Failure in Neonates: A Systematic Review and Meta-Analysis

Background: Heated humidified high-flow nasal cannula (HHHFNC) is gaining popularity as a mode of respiratory support. We updated a meta-analysis examining the efficacy and safety of HHHFNC compared with nasal continuous positive airway pressure (NCPAP) for infants. Methods: Literature searches were conducted using PubMed, Cochrane Library, OVID, Embase, Web of Science, Chinese Biomedical Literature, Weipu Journal, Wanfang, and CNKI databases up to December 2020. Only randomized controlled trials (RCTs) of HHHFNC versus NCPAP in preventing extubation failure for infants were included. Results: A total of 13 RCTs research literatures involving 2395 infants were included in the Meta-analysis. The meta-analysis showed the following results. (1) In terms of efficacy, there were no significant differences between two groups in the treatment failure rate (RR: 1.00, 95%CI: 0.73 to 1.36, P=0.99) and reintubation rate (RR: 0.86, 95%CI: 0.70 to 1.06, P=0.16). While in term of safety, HHHFNC had a significant advantage over NCPAP in reducing the incidence rates of nasal trauma (RR: 0.27, 95%CI: 0.13 to 0.56, P=0.0005) and frequent hemorrhoid (RR: 0.40, 95%CI: 0.23 to 0.70, P=0.001).(2) In terms of secondary outcome measures, there were no significant differences between two groups in hospital mortality rate and incidence rates of BPD, ROP, IVH and duration of reaching full enteral feeding(P>0.05). HHHFNC demonstrated lower incidence of NEC (RR: 0.65, 95%CI: 0.43 to 0.98, P=0.04) than NCPAP. Conclusion:this meta-analysis showed that HHHFNC appears to be similar to NCPAP in efficacy of preventing extubation failure in infants. It is associated with significantly lower odds of nasal trauma, frequent hemorrhoid and NEC.

An Unusual Case of Nasal Septal Hematoma Caused by Local Dental Anesthesia in a 15-Year-Old Girl

Introduction: Nasal septal hematoma (NSH) is a complication of nasal trauma, which its emergency treatment is drainage of hematoma. Delayed treatment may result in necrosis of the nasal cartilage and saddle nose deformity. Case Presentation: Here, we reported a 15-year-old girl presented with NSH associated with a dental local anesthetic injection, which led to nasal septum necrosis. Conclusions: Computerized tomography (CT) scanning was performed to determine the hematoma size and existence of other complications.
