Abstract Background The Covid-19 pandemic has affected all aspects of healthcare globally. Theatre utilisation assumes a substantial proportion of hospital resources, creating a streamlined pathway increases efficiency and productivity. With concerns regarding aerosol generating procedures, viral transmission to health care workers in theatre and patient pathways through the hospitals the covid-19 pandemic has added another dimension to the theatre pathway. The aim of this study was to quantify the impact of Covid-19 on the “knife to skin” (KTS) time and compare it to previous historical data (HD).   Methods Retrospective analysis of real time theatre data was analysed for the first 12 months of the pandemic from 11th March 2020 to 11th March 2021. To try and minimise variability between different specialities and operations we picked one operation to study: Laparoscopic cholecystectomy (LC). Historical data was also gathered from the same time frame over the last 5 years (2015-2020) for comparison. Data collected included emergency or elective, time sent for patient, anaesthetic start time, knife to skin time and duration of operation. Comparison of means were analysed by One-way ANOVA tests and Student’s T-Test. Results 399 laparoscopic cholecystectomies were performed during the first year of the pandemic. KTS time was calculated as operation start time minus time sent for patient.  Average time during the pandemic for emergency LC KTS was 56 minutes and 35 minutes for elective LC. Comparison of these times to HD revealed no statistical difference (Emergency LC 56 mins vs 58 mins p > 0.05, Elective LC 35 mins vs 35 mins p > 0.05). The anaesthetic time for emergency LC during the pandemic vs HD was 10 mins vs 14 mins (p < 0.05), no statistical difference was found in the elective group, 16mins vs 14mins (p > 0.05) Conclusions The Covid-19 pandemic has had no detectable effect on Knife to skin time as compared to our previous historical data. It seems the extra Covid 19 precautions involving PPE, pathways etc. have not affected theatre efficiency or utilisation. In fact, there was very little variance in KTS time over the six years studied (2015-2021) with very consistent levels for both elective and emergency procedures. The shorter anaesthetic time for emergency LC during the pandemic needs to be further investigated but one hypothesis is the unconscious or conscious decision to decrease the amount of preoxygenation to minimise aerosolisation.

Abstract Introduction General anaesthetic has traditionally been felt to be more appropriate than spinal anaesthesia for patients undergoing ureteroscopy as it is difficult to achieve a suitably high block. During the COVID-19 pandemic, our centre moved elective operating to an alternative day-case surgical environment where the anaesthetic team performed predominantly spinal anaesthesia and were therefore very experienced with this modality. In view of concerns of COVID-19 transmission by aerosolisation during the intubation and extubation phases of general anaesthetic, spinal anaesthesia as an alternative first line modality was trialled with the option of converting to general anaesthesia if surgery could not be achieved safely and comfortably for the patient. Method During a three-month period, unless contraindicated, spinal anaesthesia was used as the first line anaesthetic for ureteroscopy cases. A retrospective study of outcomes was then undertaken. Results 44 patients were treated with a conversion rate to general anaesthetic of 9% (n = 4). There was a complication rate of 20% (n = 9); 4 partial procedures, 4 readmissions with symptomatic residual fragments or sepsis and 1 patient required post-operative overnight stay due to anaesthetic. Spinal anaesthetic time averaged 25minutes. Conclusions The global COVID-19 pandemic has led to change in practice and we have demonstrated that spinal anaesthesia is a valuable alternative to general anaesthetic in the majority of ureteroscopy cases. When undertaken by an experienced anaesthetic team, using this method does not significantly add to procedure time.

Aims The aim of this study is to determine the effects of the UK lockdown during the COVID-19 pandemic on the orthopaedic admissions, operations, training opportunities, and theatre efficiency in a large district general hospital. Methods The number of patients referred to the orthopaedic team between 1 April 2020 and 30 April 2020 were collected. Other data collected included patient demographics, number of admissions, number and type of operations performed, and seniority of primary surgeon. Theatre time was collected consisting of anaesthetic time, surgical time, time to leave theatre, and turnaround time. Data were compared to the same period in 2019. Results There was a significant increase in median age of admitted patients during lockdown (70.5 (interquartile range (IQR) 46.25 to 84) vs 57 (IQR 27 to 79.75); p = 0.017) with a 26% decrease in referrals from 303 to 224 patients and 37% decrease in admissions from 177 to 112 patients, with a significantly higher proportion of hip fracture admissions (33% (n = 37) vs 19% (n = 34); p = 0.011). Paediatric admissions decreased by 72% from 32 to nine patients making up 8% of admissions during lockdown compared to 18.1% the preceding year (p = 0.002) with 66.7% reduction in paediatric operations, from 18 to 6. There was a significant increase in median turnaround time (13 minutes (IQR 12 to 33) vs 60 minutes (IQR 41 to 71); p < 0.001) although there was no significant difference in the anaesthetic time or surgical time. There was a 38% (61 vs 38) decrease in trainee-led operations. Discussion The lockdown resulted in large decreases in referrals and admissions. Despite this, hip fracture admissions were unaffected and should remain a priority for trauma service planning in future lockdowns. As plans to resume normal elective and trauma services begin, hospitals should focus on minimising theatre turnaround time to maximize theatre efficiency while prioritizing training opportunities. Clinical relevance Lockdown has resulted in decreases in the trauma burden although hip fractures remain unaffected requiring priority Theatre turnaround times and training opportunities are affected and should be optimised prior to the resumption of normal services.

Background. Retroperitoneal tumours propagate intrathoracic caval tumour thrombi (ICTT) of which we consider two subgroups: ICTT-III (extracardiac) and ICTT-IV (intracardiac). Methods. Case series review. Results. 29 series with 784 patients, 453 with extracardiac and 331 with intracardiac ICTT. Average age was 59 years. 98% of the tumours were RCC, 1% adrenal and Wilms’ tumours, and 1% transitional cell carcinomas. The prevalent incision was rooftop with or without sternotomy. Mortality was 10% (5% for ICTT-III, 15% for ICTT-IV). Morbidity was 56% (36% for ICTT-III, 64% for ICTT-IV) and reoperation for bleeding was the commonest complication (14%). Mean Blood loss was 2.6 litres for ICTT-III and 3.7 litres for ICTT-IV. Mean blood product use was 2.4 litres for ICTT-III and 3.5 litres for ICTT-IV. Operative and anaesthetic times exceeded 5 hours. Hospital stay averaged 13 days. Variations in perioperative care included preoperative embolisation, perioperative transoesophageal echo, surgical incisions, and extracorporeal circulation. Brief Summary. Surgery for ICTT has high transfusion, operating/anaesthetic time, and in-hospital stay requirements, and intracardiac ICTT also attract higher risk. Preoperative tumour embolisation is controversial. The cardiothoracic team offers proactive optimisation of blood loss and preemptive management of intracardiac thrombus impaction: we should always be involved in the management the ICTT.
