Perioperative management of lithium in the patient undergoing pituitary surgery: a case report.

Lithium is a psychotropic drug used primarily in the treatment of bipolar disorder. It is renally excreted and characteristically causes nephrogenic diabetes insipidus as an adverse drug reaction. Lithium also requires serum level monitoring as there is a narrow therapeutic window and untreated toxicity can result in neurological sequelae including drowsiness, coma, seizures, and ultimately death. We present the case of a 65-year old man admitted for pituitary surgery complicated by post-operative difficult fluid management and subsequent lithium toxicity. We highlight this rare situation and the need to be vigilant in the peri-operative period with any patients on lithium who undergo pituitary surgery.

Intra-operative use of biological products-Are we aware of their derivatives?

INTRODUCTION: Global medical advances within healthcare have subsequently led to the widespread introduction of biological products such as grafts, haemostats, and sealants. Although these products have been used for many decades, this subject is frequently not discussed during the consent process and remains an area of contention. METHODS: A nationwide confidential online survey was distributed to UK-based junior registrars (ST3-5), senior registrars (ST6-8), post-CCT fellows, specialist associates/staff grade doctors and consultants working in general/vascular surgery, neurosurgery, otolaryngology, oral and maxillofacial surgery and plastic surgery. RESULTS: Data were collected from a total of 308 survey respondents. Biological derivatives were correctly identified in surgical products by only 25% of survey respondents, only 19% stated that they regularly consent for use of these products. Our results demonstrate that most participants in this study do not routinely consent (81%) to the intra-operative use of biological materials. An overwhelming 74% of participants agreed that further education on the intra-operative use of biological materials would be valuable. DISCUSSION: This study highlights deficiencies in knowledge that results in potential compromise of the consenting process for surgical procedures. A solution to this would be for clinicians to increase their awareness via educational platforms and to incorporate an additional statement on the consent form which addresses the potential intraoperative use of biological products and what their derivatives may be. CONCLUSION: Modernising the current consent process to reflect the development and use of surgical biological products will help to ensure improved patient satisfaction, fewer future legal implications as well as a better surgeon-patient relationship.

Personal protective equipment guidance during a global pandemic: A statistical analysis of National perceived confidence, knowledge and educational deficits amongst UK-based doctors.

INTRODUCTION: On the 11th of March 2020, the World Health Organisation (WHO) declared a global pandemic following the upsurge of the novel coronavirus disease 2019 (COVID-19). Unprecedented global demand for personal protective equipment (PPE) resulted in restricted availability, as well as evolving guidance on use, the latter of which was complicated by conflicting guidance provided by numerous healthcare bodies. AIM: To assess perceived confidence and knowledge of PPE guidance as published by Public Health England (PHE) amongst doctors of varying specialties and grades. METHOD: A nationwide 11-point survey comprising of multiple-choice questions (MCQs) and a 5-point Likert scale assessing perceived confidence was disseminated to UK-based doctors using multiple platforms. Statistical analysis using one-way analysis of variance (ANOVA), Tukey's honest significant difference (Tukey HSD) and Pearson's chi-squared test was undertaken to assess for statistical significance. RESULTS: Data collated from 697 respondents revealed that average perceived confidence was low across all specialties and grades. Notably, 59% (n = 411) felt they had received insufficient education regarding up-to-date guidance, with 81% (n = 565) advocating further training. Anaesthetics and ophthalmology were highest and lowest scoring specialties in knowledge-based MCQs, achieving scores of 59% and 31%, respectively. Statistical analysis revealed significant differences between specialty, but not grade. CONCLUSION: Ensuring uniformity in published guidance, coupled with education may aid knowledge and subsequent confidence regarding the appropriate use of PPE. The absence of a unified consensus and sustained training not only poses significant ramifications for patient and healthcare professional (HCP) safety, but also risks further depletion of already sparse resources. Because of the novelty of COVID-19, appropriate PPE is continually evolving leaving an absence in formal training and education. This paper reveals insight into confidence and knowledge of PPE amongst doctors of various specialities/grades during a global pandemic, highlighting key deficits in education and training.

Endoscopic transsphenoidal surgery reconstruction using the fibrin sealant patch Tachosil®.

INTRODUCTION: The incidence of CSF leak following endoscopic transsphenoidal surgery remains the most important measure in the success of any repair. The nasoseptal flap (NSF) has played a pivotal role in reconstructing defects. However, morbidity associated with the NSF includes bleeding, septal injury, altered smell and crusting. Tachosil® is an absorbable fibrin sealant patch that promotes haemostasis and wound healing. The purpose of this study was to evaluate the effectiveness of Tachosil® to repair intraoperative defects during an endoscopic transsphenoidal approach. MATERIALS AND METHODS: All patients who underwent an endoscopic transsphenoidal approach with the use of Tachosil® at the Queen Elizabeth Hospital Birmingham, between January 2013 and June 2020 were retrospectively analysed. Tachosil® was used as an overlay patch over of the bony defect, in a multi-layered repair depending on the defect and grade of CSF leak. The primary outcome measure was post-operative CSF leak. RESULTS: A total of 52 primary procedures where Tachosil® was used as the overlay were analysed. There were 23 (44.2%) intraoperative CSF leaks. The overall post-operative CSF leak rate was 7.8% (n = 4), with all cases having had a Tachosil® overlay reconstruction with no NSF. A formal NSF was harvested in only five cases alongside the Tachosil® patch, where a grade 2 or more leak was identified at the time of the primary procedure, none of which developed a post-operative leak. No patient had any post-operative adverse outcomes that were attributed to Tachosil®. CONCLUSIONS: We believe this to be the largest case series evaluating the endoscopic use of Tachosil® in skull base reconstruction. Our data show that in endoscopic transsphenoidal approach, Tachosil® may be used safely in a multi-layered approach as an effective alternative to the NSF in low flow CSF leak cases, or alongside a NSF in higher flow leaks.

Emergency management of neck stoma patients during the coronavirus pandemic: a national nurse survey.

BACKGROUND: Neck stoma patient care involves significant clinical complexity. Inadequate staff training, equipment provision and infrastructure have all been highlighted as causes for avoidable patient harm. AIMS: To establish the perception of knowledge and confidence levels relating to the emergency management of neck stomas among UK nurses during the COVID-19 pandemic. METHOD: A nationwide prospective electronic survey of both primary and secondary care nurses via the Royal College of Nursing and social media. FINDINGS: 402 responses were collated: 81 primary care and 321 secondary care; the majority (n=130) were band 5. Forty-nine per cent could differentiate between a laryngectomy and a tracheostomy; ENT nurses scored highest (1.56; range 0-2) on knowledge. Fifty-seven per cent could oxygenate a tracheostomy stoma correctly and 54% could oxygenate a laryngectomy stoma correctly. Sixty-five per cent cited inadequate neck stoma training and 91% felt inclusion of neck stoma training was essential within the nursing curriculum. CONCLUSION: Clinical deficiencies of management identified by nurses can be attributed to a lack of confidence secondary to reduced clinical exposure and education.

Personal protective equipment: knowledge of the guidance.

BACKGROUND: On 11 March 2020, the World Health Organization (WHO) declared a global pandemic in the wake of the coronavirus disease 2019 (COVID-19) outbreak. The unpredictable nature of transmission of COVID-19 requires a meticulous understanding of guidance on personal protective equipment (PPE) as published by WHO and Public Health England (PHE). AIM: To assess perceived confidence and knowledge of PHE guidance relating to PPE by nursing staff. METHODS: A nationwide survey was disseminated between May and June 2020 through social media platforms as well as internal mail via regulatory bodies and individual hospital trusts. RESULTS: Data were collated from 339 nurses. Perceived confidence as measured on a Likert scale was a mode score of 3/5, with the average score for knowledge-based questions being 5/10. Of the respondents, 47% cited insufficient training on PPE guidance, and 84% advocated further training. Conclusions: Unifying published PPE guidance and ensuring consistency in training can improve awareness, confidence, and knowledge among nursing staff.

Nurse-led epistaxis management within the emergency department.

BACKGROUND: the incidence of epistaxis has increased secondary to increased life expectancy and morbidities. This study sought to assess the knowledge, practice and opinion relating to adequacy of training of advanced nurse practitioners (ANPs) and staff nurses (SNs) in the emergency department. METHODS: a national survey was distributed over an 8-week period; this included a 3-point scoring system based on the National Institute for Health and Care Excellence Clinical Knowledge Summaries guidance on epistaxis management to assess overall performance. RESULTS: analysis included 109 ANPs and 101 SNs; 12% of ANPs achieved the maximum score, 40% scored 2, 25% scored 1, and 23% scored 0, while 14% of SNs achieved the maximum score, 24% scored 2, 29% scored 1, and 32% scored 0. Overall 88% of respondents advocated further training. CONCLUSION: significant deficits in knowledge regarding epistaxis management were highlighted. Further training could help to empower patients in basic first aid measures, subsequently reducing admissions rates.

Neck stoma patients: is vital information displayed at the bedside?

Tracheostomies are common procedures in head and neck and critical care practice, with 50% of airway-related deaths attributable to complications such as occlusion or displacement. The National Tracheostomy Safety Project (NTSP) published guidance regarding emergency management of neck stoma patients. A prospective multicentre regional audit of all neck stoma inpatients (ward and intensive care unit (ICU) settings) was conducted. Bed spaces were assessed for tracheostomy care bundles and essential stoma information, as recommended by the NTSP guidelines. The results demonstrate inadequate ward compliance across all three trusts, with ICU compliance greater in comparison to a ward environment. Of note, crucial information regarding the nature of stoma and whom to contact in the event of an emergency, was not displayed in the majority of cases. A greater awareness of the NTSP guidance and implementation of vital information is a necessity across all disciplines in order to reduce stoma complication-related morbidity and mortality.

Carolyn's window approach for spontaneous frontal sinus meningoencephalocele.

Spontaneous meningoencephaloceles (MECs) are sparsely documented in the literature. Those occurring in the frontal sinus are an exceedingly rare entity. MECs are commonly associated with cerebrospinal fluid (CSF) rhinorrhoea. CSF rhinorrhoea is frequently misdiagnosed, causing delays in diagnosis and management. The subsequently increased risk of bacterial meningitis can be life-threatening to patients. We report the case of a woman in her late 70s with a spontaneous frontal sinus MEC, presenting with a 6-month history of CSF rhinorrhoea. The patient was successfully treated using the novel Carolyn's window approach endoscopically; 9-month follow-up revealed no skull-base breach. Our case emphasises the importance of considering MEC as a differential diagnosis for clear rhinorrhoea and demonstrates successful repair through a novel surgical approach.

Endonasal endoscopic management of spontaneous cerebrospinal fluid rhinorrhoea: The Birmingham UK experience.

BACKGROUND: Spontaneous cerebrospinal fluid (CSF) leaks (SCSFL) occur in the absence of trauma, surgery, or underlying intracranial pathology. They represent a significant healthcare burden on patients with complications such as meningitis. We present our experience of SCSFL repair via the endonasal endoscopic approach. METHODS: All patients who underwent CSF fistula repair at a tertiary UK hospital, between 1st January 2012 to 31st December 2019, were identified and had their case notes analyzed retrospectively. RESULTS: There were 33 patients included consisting of 27 (81.8%) females, with age range from 31 to 81 years (mean 55.2). Mean body mass index (BMI) was 35.2 kg/m2 , with 32 (97.0%) patients overweight (BMI >25). All patients presented with intermittent watery rhinorrhoea and had a positive biochemical analysis. Computed tomography (CT) and/or magnetic resonance imaging (MRI) identified leak sites in 29 patients (87.9%). The most common intraoperative defect site was the cribriform plate (42.4%). A variety of closing techniques were used including onlay grafts (72.7%), tissue glue (87.9%), nasoseptal flaps (63.6%), mucosal free grafts (21.2%), fat grafts (21.2%), and additional support materials (87.9%). Nasal packing was used in all patients. The average length of stay was 1.6 days. Postoperative complications occurred in two patients (6.1%) (meningitis, epistaxis). Overall, there was a successful primary repair in 32 (97.0%) patients with most cases employing a multilayered reconstruction method (78.8%). CONCLUSION: Our results demonstrate excellent success rates with the endoscopic endonasal approach to SCSFL. This adds to the literature by demonstrating a detailed analysis of the experience in SCSFL management in one of the largest UK centres.

The Effectiveness of a Specific Foundation Year 1 Induction Programme in Improving Confidence for Newly Qualified Doctors in the UK.

Background: Despite the completion of 5 or 6 years of undergraduate study, the transition to a newly qualified foundation year 1 doctor (FY1) in the UK has been recognised as challenging. We created a specific FY1 Induction Programme and aimed to evaluate its effectiveness on perceived confidence and preparedness for newly qualified doctors by assessing their responses to surveys before and after the delivery of the course. Methods: Pre- and post-course surveys were administered at the start and end of the course, respectively. All questions were subjective and used a 5-point Likert scale (1, not at all confident, to 5, definitely confident) to assess perceived confidence in a range of questions before and after the course. Results: A total of 35 participants completed the pre-course survey and 41 completed the post-course survey. For all questions, there was a statistically significant increase in confidence ratings. All 41 participants completing the post-course questionnaire responded 'yes' to feeling more confident to be an FY1 after completing the programme compared to before (100%). Conclusions: Our study, along with previously published work, has shown a repeatable positive effect with implementation of transition courses for newly qualified doctors. Future research in this area could focus on more large-scale standardised learning events incorporated by different trusts prior to commencement as an FY1, to see if the positive effects found in our study are translatable across other regions.

Reconstruction and Cerebrospinal Fluid Leaks in Endoscopic Endonasal Approach for the Management of Clival Chordomas-A Systematic Review.

The success of the endoscopic endonasal approach (EEA) to surgically manage clival chordomas (CC) relies on robust repair methods to reduce complications, such as cerebrospinal fluid (CSF) leaks. Our study aims to evaluate the existing literature to assess reconstructive techniques utilised and post-operative CSF leak rates in this cohort. A systematic review and analysis was performed of all published data related to CC patients managed with an EEA. A total of 24 articles were included, representing 363 patients and 396 procedures. A variety of reconstruction methods were used with 95.9% of studies using an intracranial repair graft, 70.8% using a nasoseptal flap (NSF), 62.5% using glue/haemostat, 58.3% using nasal packs and 75.0% employing multi-layered reconstruction. Post-operative CSF leak rate was 10.1%. The leak rate was less in subgroups where a NSF was used (9.4%) although this was not statistically significant (p = 0.273). There were no differences in leak rates when glue/haemostat (p = 0.139) or nasal packs (p = 0.550) were used. Our review is the most up-to-date synthesis of the existing literature surrounding the EEA to CCs assessing reconstruction and post-operative CSF leaks. It demonstrates most authors employ a multi-layered reconstruction method. The lack of statistical significance observed for CSF leaks in subgroups is likely due to a variety of cofounding surgeon and patient factors. Higher quality prospective randomised multi-centric studies, with reporting of specific repair techniques will enable future systematic reviews to provide a more accurate consensus regarding optimal methods of reconstruction in this field.

The efficacy and safety of intrathecal fluorescein in endoscopic cerebrospinal fluid leak repair -a systematic review.

BACKGROUND: Effective management of cerebrospinal fluid (CSF) leaks can reduce significant associated morbidity. Intrathecal fluorescein (IF) may be a valuable intra-operative adjunct to localise leak sites. Recent reports have demonstrated low doses of IF to be safe, however, no internationally accepted dose of IF has been agreed. OBJECTIVE: To assess the efficacy and safety of IF used in the endoscopic management of anterior skull base CSF fistulae. METHODS: A systematic review and descriptive analysis were performed of all published data in accordance to PRISMA guidelines. RESULTS: There were 18 included articles giving a total of 335 procedures where IF was used. Doses of IF ranged from 10mg - 150mg. IF positively identified the site of CSF fistula in 88.7% of cases (n = 297). There was a total of 25 reported peri-operative complications in all included studies (7.5%) with 5.1% (n = 17) potentially related to IF use. Of these, the complication rate was 3.9% at low IF doses (<50mg) and 80.0% at higher doses (≥50mg). CONCLUSION: Our review demonstrates that IF is effective at localising CSF fistulae with most significant complications being related to doses ≥50mg. We therefore propose that there is a potential for the licensing of IF in this field. Doses <50mg have consistently been shown to be safe while still maintaining effective localisation rates. Based on the most common doses used in this group, we recommend utilisation of a dosing below 50mg, with the most frequent range being between 10-30mg.

The Effect of COVID on Nasal Fracture Management in ENT Emergency Clinics.

Study design: Retrospective cohort study. Objective: Management of nasal fractures is usually in ENT emergency clinics, with our center aiming to assess patients within 10-days. During 2020, there have been numerous lockdowns and social distancing measures implemented in the UK as a result of the coronavirus pandemic (COVID). This study aimed to assess the effect of COVID on nasal fracture management in ENT emergency clinics in terms of number of patients seen, time to follow up and their management strategies. Methods: All patients with suspected or confirmed nasal bone fractures presenting to the emergency department (ED) between January 1, 2019 and December 31, 2020 at our major trauma center were analyzed in 2 groups depending on the year they were seen (2019 vs. 2020). Results: There was a total of 104 patients analyzed, with 51.4% decrease in the number of patients seen in 2020 versus 2019. The mean days to follow up in 2019 was 8.09 days and 7.65 days in 2020 (P = .37). There was no statistically significant difference in the number of patients seen within the 10-day target between years (2019 = 65.7% vs. 2020 = 76.5%, P = .35). The majority of patients were managed with manipulation under anesthesia (MUA) in 2019 (n = 32, 45.7%) vs. discharge from clinic in 2020 (n = 21, 61.8%). Conclusions: Our study shows a drastic reduction in the number of patients seen in ENT emergency clinic from 2019 to 2020. This is in-keeping with other studies that have shown a reduction in ED attendances, trauma admissions and admissions across other specialties all around the world.

Prevalence of Patients Who Return to Theatre Post-Adenoidectomy: A Review of Hospital Episode Statistics Data (2012-2019).

Introduction Risk of surgical intervention for post-adenoidectomy haemorrhage can be assessed with the analysis of the Hospital Episode Statistics (HES) data. Materials and methods HES data for England from 2012 to 2019 were analysed comparing the coded number of adenoidectomy procedures to the number of surgical arrests of post-adenoidectomy haemorrhage in adolescents/adults and children. Results Between April 2012 and April 2019, of 47,597 procedures, 52 (0.11%) patients required surgical arrest of post-adenoidectomy haemorrhage. In adults (n = 5,379), 11 patients returned to theatre for control of post-operative bleeding, whereas 41 children (n = 42,218) required this intervention. The total number of adenoidectomies was 3.7 times higher in children; however, adults were statistically two times more likely to require further surgical intervention for arrest of post-adenoidectomy haemorrhage (two-tailed p-value = 0.0031). Conclusion Children are more likely to return to theatre for surgical arrest of post-adenoidectomy haemorrhage, with p-values indicating the difference between the incidence of adults and children returning to theatre to be very statistically significant.

A Safe Approach to Percutaneous Tracheostomy for COVID-19 Patients in Intensive Care.

The novel coronavirus disease 2019 (COVID-19) has placed a burden on critical care facilities worldwide. Patients who remain critically unwell with COVID-19 require prolonged periods of ventilation, and the burden of both the resources during a pandemic and the slow respiratory wean must be managed. Percutaneous tracheostomies are commonplace in long-term intensive care patients, yet little is known about their role in COVID-19, particularly how operator safety is maintained during the procedure. Here, we describe an approach designed to minimize cross-infection of the operators undertaking percutaneous tracheostomies within this subset of patients. Focus should be on non-technical skills, prolonged periods of pre-oxygenation, and minimal ventilation during the procedure to minimize the risk of aerosolization generated from an open breathing system. Our modified technique demonstrates successful early experiences with no operators testing positive for COVID-19 or developing symptoms following any performed procedure.

The Effectiveness and Safety of Intrathecal Fluorescein in the Management of Cerebrospinal Fluid Leaks.

BACKGROUND: Cerebrospinal fluid (CSF) leaks can be associated with significant morbidity such as meningitis. Surgical management has proven effective, with endoscopic approaches having become the gold standard due to success rates >90%. Inability to localise the leak site prior to surgery is associated with surgical failure. The use of intrathecal fluorescein (IF) to localise CSF fistulae sites was first demonstrated in 1960. Despite this, its use in this context is unlicensed. OBJECTIVE: Evaluate the safety and efficacy of IF use in the management of CSF leak repairs in our centre. METHODS: All patients who underwent endoscopic repair of CSF fistula by a single surgeon where IF was used between January 2010 - September 2019 at a single-centre (tertiary skull base referral unit in the United Kingdom) were retrospectively analysed. Primary outcome measures were localisation of CSF fistula with IF (efficacy) and peri-operative complications likely to be attributable to IF (safety). RESULTS: There were 55 patients included (60 procedures) with a positive localisation rate of 90.0% with IF. The overall peri-operative complication rate was 8.3% (n = 5). It is likely that none were related to IF use. However, three complications may be linked giving a complication rate potentially related to IF of 5.0%. There were no peri-operative mortalities. CONCLUSION: Many studies have demonstrated IF to be safe at low doses (<50mg) with a high sensitivity, specificity and positive predicative value. Our results demonstrate that the use of IF in our centre is safe and effective at identifying CSF fistulae. While we have reported some complications in our cohort, these were unlikely to be directly attributable IF use. We have described no serious complications such as seizures, limb weakness or death. We believe this study adds to the growing body of evidence that IF use in the management CSF fistula repairs is safe and effective.

The evolution of sinus surgery in England in the last decade - An observational study.

BACKGROUND AND OBJECTIVE: Sinus surgery has seen significant changes over the years with advancements in instruments, endoscopes and imaging. This study aimed to use Hospital Episode Statistics (HES) data to review the total number of sinus related procedures performed in both adults and children across England and identify whether there were any trends across the study period. We predicted an increase in endoscopic sinus procedures with a decline in open approaches to the paranasal sinuses. METHODS: Data from HES was extracted for the years 2010-2019. The operative (OPCS-4) codes relevant to all sinus procedures between E12.1 and E17.9 were analysed. After examination of overall sinus related procedures, further subgroup analysis was performed with regards to open or endoscopic techniques. RESULTS: The total number of sinus procedures performed between 2010 and 2019 was 89,495. There was an increase in endoscopic surgeries by 21.1% and a decrease of open surgeries 35.3% during this time. There was an overall increase in maxillary, frontal and sphenoid sinus procedures, with a decrease in ethmoid sinus and lateral rhinotomy operations. There was an increase in the proportion of endoscopic cases overall by 5.7% and for all sinuses individually. CONCLUSION: Overall, we see an increase in sinus surgery over the last 9 years from 2010 to 2019. These findings are in keeping with our initial hypotheses. Although our data set is limited by coding, and lack of patient factors, it represents most, if not all, of the data in England over a large study period. It is therefore useful to add to previous studies when demonstrating the increasing popularity of endoscopic sinus surgery over open procedures.
