Perioperative Anaesthetic Management of a Large Paraganglioma Compressing Abdominal Aorta and Inferior Vena Cava: A Case Report

Paragangliomas (PGs) are rare neuroendocrine tumors that originate in the autonomic nervous system. Functionally, they are highly vascular and may be parasympathetic or sympathetic. Parasympathetic tumors are usually asymptomatic and inactive, located mostly in the skull base in the distribution of IX and X cranial nerves. In contrast, sympathetic tumors are highly active (secretes norepinephrine) and symptomatic and mainly located in the abdomen and pelvic regions. Surgical removal of these tumors is curative and key to favorable outcomes. Some of these tumors have malignant potential as well. Meticulous preoperative preparation is needed but many patients may still land up in hypertensive crises intraoperatively which should be managed promptly and cautiously by the anesthesia team to reduce morbidity and mortality during surgery. Here, we describe the successful anesthetic management of a patient diagnosed with large aortocaval PG abutting the aorta and compressing the inferior vena cava and bilateral renal veins.

Comparative analysis of combined spinal–epidural anesthesia and general anesthesia in percutaneous nephrolithotomy: a prospective study on surgical team and operating room personnel satisfaction

ObjectiveWe aimed to investigate the efficacy and complications of combined spinalepidural anesthesia and general anesthesia in percutaneous stone surgery prospectively.Materials and methodsThe study prospectively included patients who underwent percutaneous nephrolithotomy with general anesthesia (Group.1) or combined spinal–epidural anesthesia (Group.2) at the Department of Urology, Training and Research Hospital, Karabuk University. between December 2018 and December 2019. The effect of the anesthesia technique on the comfort and satisfaction of the operating room personnel, surgeon and anesthesia team were prospectively evaluated and recorded.ResultsDuring the postoperative period, the spinal anesthesia group had a significantly lower visual analog score than the general anesthesia group. No patient in either group required narcotic analgesics during the postoperative period. In terms of overall satisfaction scores, the surgeon performing the surgical procedure had a significantly higher satisfaction score in the general anesthesia group than in the CSEA group. The score was considered good in the general anesthesia group and moderate in the CSEA group. Personnel satisfaction was higher in the patient group that underwent CSEA. In the general anesthesia group, the score was considered to be average. In the CSEA group, the satisfaction score was considered good, with a statistically significant difference (p < 0.05). The anesthesia team’s satisfaction score was moderate, with no significant difference between the CSEA and general anesthesia groups (p > 0.05).ConclusionPCNL under CSEA can be performed safely in certain individuals. Different anesthetic techniques may have varied levels of satisfaction among the surgical team.

What Is the Incidence of Anesthesia-Related Adverse Events in Oral and Maxillofacial Surgery Offices? A Review of 61,237 Sedation Cases From a Large Private Practice Consortium

BackgroundThe safety of the anesthesia team model performed in oral and maxillofacial surgery (OMS) offices has been criticized by professional and mainstream media. PurposeThis study aims to assess the incidence of adverse anesthetic events (AE) associated with the OMS anesthesia team model and identify risk factors associated with AEs. Study design, setting, sampleThis was a retrospective cohort study utilizing a patient database from Paradigm Oral Health®, Lincoln, Nebraska, a managed service organization (MSO). Subjects included were 14 and older, undergoing open-airway intravenous anesthesia for ambulatory OMS procedures using the OMS anesthesia team model at multiple private practices in the MSO network between June 30th, 2010, and September 30th, 2022. Exclusion criteria included patients younger than 14 or patients with incomplete medical records. Predictor variablePrimary predictor variables were age, sex, American Society of Anesthesiologists physical status classification system (ASA) score, type of surgical procedure performed, and the types of medications administered during sedation. Main outcome variableThe presence of an AE. The definition of an AE was modeled on the World Society of Intravenous Anesthesia (SIVA) definition. All AEs were identified through surrogate markers which were identified through chart review. One example of an AE is ventricular fibrillation, which necessitates application of medications, here the medication is the surrogate marker. CovariatesNone. AnalysesThe data were analyzed using t-tests and χ2 tests. P values ≤.05 were considered statistically significant. ResultsIncluded in the study were 61,237 sedation cases (53.87% female and 46.13% male), for 56,076 unique patients ranging from 14 to 98 years of age (mean 33.26 ± 18.35). An AE incidence of 3 per 100,000 per year (25 total events) was observed. Neither age, sex, ASA score, nor type of surgical procedure exhibited statistically significant associations with AEs. A statistically significant association was found between AEs and fentanyl (P = 0.0008). Conclusions and RelevanceThis investigation shows a smaller incidence of AEs than previous studies of the OMS anesthesia team model.

The Growing Trend of Degenerative Spine Surgery Under Spinal Anesthesia in the Elderly: Empowering Patient Safety: A Series of 83 Cases

Objective: Awake spine surgery has improved patient outcomes in common orthopaedic procedures. Integrating it into spine surgery is of interest to surgeons since it may reduce the difficulties and complications associated with general anaesthesia. The demand for safe spine surgery is rising due to healthcare improvements and increasing ageing population. This study aimed to assess the safety and feasibility of spine surgery under spinal anesthesia for elderly patients aged 65 and older.Methods: In a retrospective review, 83 lower lumbar spine surgeries performed under spinal anesthesia by a single surgeon at a single hospital from 2015 to 2019 were examined. All procedure-related data was collected prospectively for analysis. This study explored demographic characteristics, surgical features, perioperative concerns, and anesthesia-related obstacles in spine surgery under spinal anaesthesia.Results: This study included 83 patients aged 65 years and older. Following follow-up, visual analogue scale and Oswestry Disability Index scores considerably improved (p&lt;0.05). Patients in the American Society of Anesthesiologists physical characteristics classification grade II had the highest count. The most common level was L4–5. About 7.2% of patients needed multiple spinal procedures. The average induction time was 20.2±9.6 minutes. The average intraoperative operation lasted 84.0±17.20 minutes. The shifting-out process took 7.95±2.10 minutes to start. The mean intraoperative arterial blood pressure was 70.7±10.8 mmHg, and the mean heart rate was 69.0±7.2 beats per minute. The average postoperative analgesia initiation time was 79.9±7.7 minutes. The average postoperative stay was 3.02±0.83 days. In 10.8% of individuals, cerebrospinal fluid was found. 1.2% of patients experienced postoperative hypotension, 12% experienced nausea and vomiting. Infection occurred in 2.4% of patients, and 14.5% experienced post-operative urinary retention.Conclusion: This case series shows that older patients can undergo lumbar fusion, decompression surgeries under spinal anesthesia with a skilled anaesthesia team. Additionally, spinal anaesthesia substantially minimised dangers and concerns related with general aanaesthesia.

Anesthetic Considerations for Patients with Hereditary Neuropathy with Liability to Pressure Palsies: A Narrative Review.

Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal dominant demyelinating neuropathy characterized by an increased susceptibility to peripheral nerve injury from trauma, compression, or shear forces. Patients with this condition are unique, necessitating distinct considerations for anesthesia and surgical teams. This review describes the etiology, prevalence, clinical presentation, and management of HNPP and presents contemporary evidence and recommendations for optimal care for HNPP patients in the perioperative period. While the incidence of HNPP is reported at 7-16:100,000, this figure may be an underestimation due to underdiagnosis, further complicating medicolegal issues. With the subtle nature of symptoms associated with HNPP, patients with this condition may remain unrecognized during the perioperative period, posing significant risks. Several aspects of caring for this population, including anesthetic choices, intraoperative positioning, and monitoring strategy, may deviate from standard practices. As such, a tailored approach to caring for this unique population, coupled with meticulous preoperative planning, is crucial and requires a multidisciplinary approach.

Anesthesia start time documentation accuracy where peripheral nerve block is the primary anesthetic.

When used as the primary anesthetic, nerve blocks are not billed as separate procedures. In this scenario, the anesthesia start (AStart) time should include the block procedural time. We measured how often AStart time was documented before the nerve block was placed in the preoperative area, and compared cases where a block team performed the nerve block and cases where the intraoperative anesthesia attending supervised the nerve block. We hypothesized that the involvement of a regional anesthesia team would lead to more accurate documentation of AStart. We also estimated the lost revenue due to inaccurate start time documentation. The study population were patients undergoing surgery with a peripheral nerve block as the primary anesthetic. For this analysis, AStart occurring less than 10 min before the in-operating room time was defined as potentially inaccurate. Lost potential revenue was estimated by taking the difference between the documented time of local anesthetic administration and the documented AStart time. A total of 745 cases were analyzed. Overall, 439 cases (58%) cases were identified as having potentially inaccurate start times. There were higher rates of inaccurate AStart documentation by the block team (316/482, 65.5%) compared with blocks supervised by the in-room anesthesia attendings (123/263, 46.7%, p<0.001). Overall, the estimated loss in billable revenue during the study period was a total of $70 265. The performance of primary regional anesthesia procedure by a block team increased the incidence of inaccurate documentation and uncaptured potential revenue. There is need for education about accurate nerve block documentation for anesthesiologists, especially when separate teams are used.

Assessing the Anaesthetic Time on Operation Theatre Utilisation and Case Cancellation

The time to perform an anaesthesia-related procedure at induction and emergence is often overlooked as part of the operation theatre (OT) utilisation time. This prospective observational study aimed to assess the estimation done by the surgeons and anaesthetists on anaesthesia times and the overall OT utilisation in our centre. This prospective observational study included elective cases from 13 surgical disciplines. The trainees, specialists and consultants from surgical and anaesthesia teams estimated the anaesthesia times separately before the surgical procedures. The actual anaesthesia, surgical, total procedural and turnover durations taken to complete the cases were documented. Operation theatre utilisations of those various surgical disciplines involved in the study were also analysed. We analysed 128 elective cases. The average mean time spent for anaesthesia procedures was 28.4 ± 14.1 min, with the mean induction time was 16.0 ± 9.8 min and the mean emergence time was 12.5 ± 8.6 min. Both anaesthetists and surgeons overestimated the anaesthetic times, but anaesthetists estimated closer to the actual anaesthetic times (r = 0.64 vs r = 0.49, respectively). There was no significant difference in the estimated anaesthetic times between different experience levels. All the surgical disciplines had average OT utilisation exceeding 90%, indicating overutilisation. A total of 12 cases (7.1%) were cancelled. Most cases were cancelled due to exceeded allocated block OT times (7 cases) or unavailability of ICU beds (2 cases). We concluded that OTs exceeding the given OT time is the most frequent reason for cancelling elective surgical cases on the day of surgery.

Perioperative Antibiotic Prophylaxis.

Postoperative surgical site infections (SSI) account for almost 25% of all nosocomial infections in Germany and are a source of increased morbidity and mortality. This review is based on pertinent publications retrieved by a selective search in PubMed and on national and international guidelines. The individual risk factors for SSI must be assessed before any surgical procedure. A body-mass index above 30 kg/m2 is associated with an unadjusted risk ratio of 1.35 [1.28; 1.41] for SSI, which rises to 3.29 [2.99; 3.62] if the patient is also immunosuppressed. The risk of SSI is also significantly higher with certain types of procedure. Perioperative antibiotic prophylaxis (PAP) is clearly indicated for operations that carry a high risk of SSI (e.g., colorectal surgery) and for those that involve the implantation of alloplastic material (e.g., hip endoprostheses). PAP can usually be administered with basic antibiotics such as cefazoline. The basic principles of PAP are that it should be given by the anesthesia team in the interval from 60 minutes preoperatively up to shortly before the incision, and that its administration should only be for a short period of time, usually as a single shot. Continuing PAP onward into the postoperative period leads to increased toxicity, bacterial superinfections, and antibiotic resistance. The evidence shows that perioperative antibiotic prophylaxis is a component of a bundle of measures that can help prevent SSI. Strict indications and adherence to the basic principles of PAP are essential for therapeutic success.

Enhancing Drug Management, Cost Savings, and Staff Satisfaction in Anesthesiology: A Quality Improvement Project in a Chinese Tertiary Hospital.

In alignment with China's national directive for improved drug management in anesthesiology, the Affiliated Hospital of Qingdao University initiated a quality improvement project, aiming to tackle the prevailing challenges of inefficiencies in drug administration, escalating drug costs, and the notable communication gap between pharmacists and anesthesiologists. We employed a Plan-Do-Study-Act methodology to establish a pharmacy team and execute a multidimensional pharmaceutical intervention. The interventions included the formulation of standard procedures, guidelines and regulations, assistance from an information system (including automatic dispensing cabinets and prospective prescription review system), communication feedback (via WeChat groups), and education for anesthesiology staff. The intervention spanned from April to September 2023, focusing on optimizing medication management, achieving cost savings, and enhancing the satisfaction of anesthesia team members, with an additional observation from October to December 2023. Following the interventions, improvements were observed in drug management practices. These enhancements included increased compliance with accounting procedures, more rigorous registration of controlled substances, and more effective disposal of liquid residues. There was no adverse events related to high-alert medications or look-alike drug usage errors. The introduction of automatic dispensing cabinets and a prospective prescription review system markedly improved work efficiency. The utilization of a WeChat group facilitated effective communication about unreasonable prescriptions and drug-related issues. Among the 29,061 patients who underwent surgery both before and after the interventions, significant reductions were observed both in the drug proportion and the per capita drug costs (P = 0.03, P = 0.014, respectively). The per capita drug cost decreased by 20.82%, from ¥723.43 to ¥572.78, consistently remaining below ¥600 throughout the 9-month observation period. The per capita cost of monitoring drugs including dezocine, butorphanol, haemocoagulase agkistrodon, penehyclidine, and ulinastatin experienced a significant reduction (P < 0.05). Additionally, in the satisfaction questionnaires returned, a remarkable 94.44% of anesthesiology staff expressed high satisfaction with the comprehensive pharmaceutical interventions. The quality improvement project has yielded remarkable positive outcomes, serving as a model worthy of reference and replication in similar healthcare settings.

Prevention of hypotension after induction of general anesthesia using point-of-care ultrasound to guide fluid management: a randomized controlled trial.

Hypotension after induction of general anesthesia (GAIH) is common and is associated with postoperative complications including increased mortality. Collapsibility of the inferior vena cava (IVC) has good performance in predicting GAIH; however, there is limited evidence whether a preoperative fluid bolus in patients with a collapsible IVC can prevent this drop in blood pressure. We conducted a single-centre randomized controlled trial with adult patients scheduled to undergo elective noncardiac surgery under general anesthesia (GA). Patients underwent a preoperative point-of-care ultrasound scan (POCUS) to identify those with a collapsible IVC (IVC collapsibility index ≥ 43%). Individuals with a collapsible IVC were randomized to receive a preoperative 500mL fluid bolus or routine care (control group). Surgical and anesthesia teams were blinded to the results of the scan and group allocation. Hypotension after induction of GA was defined as the use of vasopressors/inotropes or a decrease in mean arterial pressure < 65mm Hg or > 25% from baseline within 20min of induction of GA. Forty patients (20 in each group) were included. The rate of hypotension after induction of GA was significantly reduced in those receiving preoperative fluids (9/20, 45% vs 17/20, 85%; relative risk, 0.53; 95% confidence interval, 0.32 to 0.89; P = 0.02). The mean (standard deviation) time to complete POCUS was 4 (2) min, and the duration of fluid bolus administration was 14 (5) min. Neither surgical delays nor adverse events occurred as a result of the study intervention. A preoperative fluid bolus in patients with a collapsible IVC reduced the incidence of GAIH without associated adverse effects. ClinicalTrials.gov (NCT05424510); first submitted 15 June 2022.

Characteristics of anesthetic and surgical tactics in treatment of a patient with a giant thyroid mass in a cancer center (clinical case)

This paper describes an example of radical surgical treatment of a patient with a giant retrosternal goiter complicated by compression of the organs of the neck and mediastinum. Considering all the risks and possible complications, we should take into account the fact that enlarged thyroid (T) body with retrosternal location can cause displacement and stenosis of the trachea and esophagus, and dislocation of large vessels and nerves of the mediastinum. This anatomical specificity is an imminent threat to successful treatment, and it also carries a certain risk of asphyxia and sudden death of the patient. In this clinical case, radical surgical treatment in this patient included sequential mobilization in two pleural cavities, and then the total removal of T through the traditional surgical access. The anesthetic complexity to support the surgical intervention involved both difficult intubation due to tracheal stenosis, and also the required separate ventilation of the lungs to visualize anatomical structures and mobilize a multinodular formation in two pleural cavities. Standard methods of artificial lung ventilation could be ineffective and even dangerous in this case due to the location and size of the tumor. We focused our attention on high-frequency ventilation (HFV), the best method of respiratory support during surgeries for tracheal and bronchial pathologies. The main task of the anesthetic team in this clinical case was to prevent the development of hypercapnia and hypoxia during intubation of the stenotic tracheal segment, and then adequate ventilation of the lungs with reduced area of proper gas exchange due to bilateral surgical pneumothorax. Thus, the full treatment was carried out due to the only safe method of compensating lung ventilation with anesthesia by HFV. The applied HFV method creates an adequate gas exchange in the lungs due to the small ventilation volume and high frequency of respiratory cycles per minute. HFV both prevented the development of threatening complications during intubation of the stenotic tracheal area and ensured an adequate gas exchange during successive thoracoscopic stages of thyroid tumor mobilization.

Frequency of Complications Related to Prone Position During General Anesthesia

Background: The prone position is widely used in spine and spinal cord surgeries and in reconstructive back surgery. If the patients are not placed in this position correctly and safely, or if they are not carefully displaced from a supine to a prone position, they may suffer many irreversible injuries This study aimed to determine the incidence of prone position complications during general anesthesia and surgery and related factors in the operating rooms of Mazandaran University of Medical Sciences hospitals in Iran. Methods: A total of 121 patients who were subjected to surgery in a prone position were examined in terms of complications related to this position. The variables of this study were age, gender, weight, type and duration of surgery, co-morbidity, patient’s body mass index (BMI), eye injury, airway swelling, runny nose, patient’s state of consciousness, neck stiffness, and lower jaw movement restriction. The other variables included skin bruising, redness and burning of the skin, presence of pain, sore throat and cough, hoarse voice, nausea, damage to the ear, peripheral nerves, and genital tract of men, which were recorded in the data collection sheet after obtaining information. The data were analyzed by SPSS 22 software. Results: Overall, 62% of patients were women, and the average age of patients was 45.23 years. In addition, 19.4% of patients had a BMI&gt;30. Lumbar fusion surgery was the most common surgery in the prone position (43.8%). Surgery time had a direct and significant relationship with the prevalence of complications in patients (P=0.00). The most frequent post-surgical complication in the prone position was throat problems (hoarseness, sore throat, throat swelling, and cough) with 71 patients (58.7%), followed by eye complications in the prone position with 67 patients (55.4%). Conclusion: The prone position is one of the most sensitive body positions for brain, spine, and kidney surgeries. The results of this study also showed a high prevalence of immediate complications after surgery, most of which were on the head and face of patients. Considering the sensitivity of this area and its care, taking preventive measures by the anesthesia team can guarantee the patient’s health.

Abstract 83: Early Notification Using a Novel Three-Tiered Code Stroke System Reduces Neurointerventional Team Activation Times

Background: Although Code Stroke group page systems are essential to accelerate endovascular therapy (EVT), their design and implementation has not been well-studied. We assessed a novel 3-tiered system crafted to facilitate prompt, stepped activation. Methods: An escalating 3-tiered system was designed to provide salient services with both an a) alert-be ready page, and a b) go-go-go page while minimizing false alarms. Group page levels are: 1) pre-arrival notification of possible stroke by EMS to Neurology; 2) notification of possible large vessel occlusion (LVO) by Neurology (based on cortical signs) to Neurointerventional+/Anesthesia; and 3) post-imaging notification of confirmed LVO and angiosuite decision to all services. System performance was assessed over a 1 year period September 2022 to August 2023. Results: Among 798 Code Strokes, 75 (9.4%) patients received EVT, including 45 who were EMS-arriving. Among the 45 LVO strokes treated with EVT, 26 (58%) had an early notification (EN) Level 2 page pre-imaging and 19 (42%) only a late notification (LN) Level 2 page post-imaging. Patients in the EN vs LN group were nominally older (84 vs 74), more often female (61.5% vs 47.3%), and more severely affected (NIHSS 16 vs 13). Time metrics are presented in Table 1 and Figure 1. The EN group had a near 40 minute decrease in door-to-puncture (DTP) and 50 minute decrease in door-to-reperfusion (DTR) times. Conclusion: All levels of a 3-tier (pre-arrival, pre-imaging, and post-imaging) Code Stroke group page system were activated frequently in EVT patients and pre-imaging early notification of neurointerventional and anesthesia teams was associated with markedly reduced DTP and DTR times.

The Role of TAP/RS Block in Minor Gynecologic Laparoscopic Surgery: A Randomized Clinical Trial

Objectives: The aim of the study was to compare, in patients undergoing minor gynecological laparoscopic procedures, the effects of ultrasound (US)-guided transversus abdominis plane (TAP) + rectus sheath (RS) block versus no TAP/RS block in terms of post-surgical pain control using the numeric pain rating scale (NRS) and the degree of patient satisfaction, according to the main goals of Early Recovery After Surgery (ERAS) programs. The primary outcome is to value the postoperative abdominal pain using NRS in both groups. Secondary outcomes are to evaluate blood values, presence of postoperative nausea and vomiting (PONV), postoperative ileus, level of patient expected satisfaction, time of discharge, length of stay (LOS), and the amounts of additional analgesics required. Design: In this prospective randomized controlled trial, patients were randomly assigned to loco-regional anesthesia (LRA) group, who received TAP and RS block under US guidance, or no loco-regional anesthesia (N-LRA) group. Enrolled patients were randomized 1:1 to either receive bilateral TAP/RS block with ropivacaine or sham treatment (patches were applied on the abdominal wall of the patients under general anesthesia). Participants: All patients aged between 18 and 75 years, with ASA (American Society of Anesthesiologists) physical status 1-2, undergoing laparoscopic minor gynecological surgery, were enrolled. Setting: The study was conducted to the University of Campus Bio-Medico Hospital of Rome. Methods: Half an hour before surgery, all patients received gabapentin 300 mg per os. Once the patient underwent general anesthesia, US-guided bilateral TAP/RS block was performed by the anesthesiology team, while the uterine manipulator was positioned by a gynecology resident (not involved in the study). In the operative room, all patients received the same standardized anesthetic regimen. Postoperative abdominal pain was assessed at rest, after palpation, during movement, and after a cough by evaluating the patient at 6, 12, 18, 24, 36, 48, and 72 h after surgery, using the NRS from 0 to 10 in both groups. The amount of drug used for analgesia in the first 48 h after surgery was recorded. Moreover, hemoglobin, white blood cells, and c-reactive protein levels were recorded at 24, 48, and 72 h. The presence of PONV and the postoperative ileus was recorded throughout convalescence. The expected level of patient satisfaction at discharge and finally the LOS were assessed. Limitations: The major weakness of this study is that 60 mL of 0.5% ropivacaine was administered to each patient, without considering weight differences, yet contemporary literature rarely suggests volume/dose titration in fascial blocks. Results: A total of 104 women, undergoing gynecological minor laparoscopic surgery, were enrolled and assigned to LRA group (53 pts) and N-LRA group (51 pts). Postoperative pain was significantly reduced in patients who received TAP/RS block. A reduction in the intake of non-steroidal anti-inflammatory drugs after surgery was registered in LRA group (p < 0.01). Moreover, a significant reduction of LOS (45.97 ± 9.87 vs. 65.08 ± 17.32 h; p < 0.01) and PONV was observed in the LRA group, as well as a better level of patient satisfaction at discharge (9.43 ± 0.94 vs. 8.26 ± 1.19; p < 0.01), compared to the N-LRA group. Conclusions: US-guided TAP and RS block significantly reduces postoperative pain after minor gynecologic laparoscopic surgery and improves patients’ post-operative recovery.

Improving compliance with personal protective equipment among anaesthetists through behaviour-changing interventions during the coronavirus disease 2019(COVID-19) pandemic.

Since 2020, the coronavirus disease 2019 (COVID-19) pandemic has seen many changes in our daily infection prevention behaviours so as to reduce healthcare-associated transmission of COVID-19 in patients and healthcare workers. In the early phases of the COVID-19 pandemic of 2020, there was much emphasis on compliant personal protective equipment utilization in the operating theatres (OTs) for COVID-19-positive patients. However, during this period, there was a lack of international validated protocols on the appropriate handling and subsequent storage of personal protective equipment in the context of aerosol-generating procedures in OTs for asymptomatic antigen rapid test (ART)-negative patients. Given the potential for transmission even with a negative ART due to the incubation period, our team developed a checklist of eye protection (e.g. goggles/face shield) and N95 mask handling and storage in non-isolation OTs for these patients. We sought to improve the compliance of best practices from 20% to 80% amongst junior anaesthetists in Singapore General Hospital so as to prevent infection transmission and cross-contamination in the OT through education and behaviour-changing interventions. This quality improvement project took place over 19 weeks from June to October 2020 by our team of anaesthetists and nurse clinicians in the non-isolation OT setting. To analyse the problem, we performed a root cause analysis to understand attitudes and beliefs driving their behaviour. The top 80% of cited root causes for non-compliance then guided prioritization of resources for subsequent behaviour-changing interventions. Using the comprehensive infection control checklist, we conducted several plan-do-study-act cycles while implementing this new checklist amongst junior anaesthetists. A total of 227 assessments of junior anaesthetists were made in the care of asymptomatic ART-negative patients. Compliance with correctly handling goggles post-intubation started out as 33.3% in Week 1, which improved to 78.5% by Week 19. Compliance with goggle storage and face shield disposal started out at 13.6% in Week 1 and increased to 78.6% by Week 19. We attributed this improvement to education and behaviour-changing interventions. This quality improvement project focusing on improving compliance with personal protective equipment utilization during the COVID-19 pandemic in the management of asymptomatic ART-negative patients in non-isolation OTs demonstrated the importance of interventions of education, persuasion, modelling, and training in effecting and sustaining organizational behaviour change in physicians and other healthcare personnel.

Eliminating Hands-Off Handoffs: Improvement in Perioperative Handoff Communication With a Multidisciplinary Tool Initiative.

Handoffs between the operating room (OR) and post-anesthesia care unit (PACU) require a high volume and quality of information to be transferred. This study aimed to improve perioperative communication with a handoff tool. Perioperative staff at a quaternary care center was surveyed regarding perception of handoff quality, and OR to PACU handoffs were observed for structured criteria. A 25-item tool was implemented, and handoffs were similarly observed. Staff was then again surveyed. A multidisciplinary team led this initiative as a collaboration. After implementation, nursing reported improved perception of time spent (2.63-3.68, p = .02) and amount of information discussed (2.85-3.73, p = .05). Anesthesia also reported improved personal communication (3.69-4.43, p = .004), effectiveness of handoffs (3.43-3.82, p = .02), and amount of information discussed (4.26-4.76, p = .05). After implementation, observed patient information discussed during handoffs increased for both surgical and anesthesia team members. The frequency of complete and near-complete handoffs increased (40%-74%, p < .001). A structured handoff tool increased the amount of essential information reported during handoffs between the OR and PACU and increased team members' perception of handoffs.

Dental treatment provided to special needs children under general anesthesia in a tertiary care hospital – A cross sectional retrospective study

Dental general anesthesia (DGA) can be a preferred approach for treating children with special health needs (CSHCN). It has many benefits, most importantly, the support of the anesthesia team to control the medical status and treat the patient safely. The aim of this study was to evaluate the dental treatment provided to (CSHCN) under (DGA) in a tertiary-care hospital. Moreover, to compare the dental procedures between different medical conditions. This retrospective study involves a sample of 730 children aged between (1–16 years) with complex medical conditions treated under DGA between January 2009 until April 2022. The results show that 4.93 % of these patients had DGA twice. For those children who had DGA only once, the most frequent medical conditions were neuro-developmental disorders (31.8 %), pediatric oncology (17.4 %), and behavioral disorders (autism, ADHD, etc.) (15.1 %). The average age was 6.9 years; almost half were preschool children (4–6 years old, 48.41 %) followed by younger school children (7–9 years old, 28.82 %). The most common dental procedures done were extractions followed by restorative procedures. The use of fissure sealant was significantly higher in neuro-developmental and behavioral disabilities patients than other medical conditions.

Assessment of Anaesthesia Teams' Non-Technical Skills in Clinical Practice before and after Simulation-Based Team Training: A Quasiexperimental Study.

In situ simulation-based team training of non-technical skills is considered an important initiative for preventing adverse events caused by poor teamwork among healthcare personnel. This study aimed to assess the non-technical skills of anaesthesia personnel before and after in situ simulation-based team training in a clinical setting. The study was conducted from October 2020 to June 2021 using a quasiexperimental before and after design based on video-recorded observations and ratings of anaesthesia teams' non-technical skills during anaesthesia induction in the operating room before and shortly after in situ simulation-based team training. Anaesthesia personnel were divided into 20 teams and video recorded during anaesthesia induction. The Anaesthetists' Non-technical Skills (ANTS) system was used to score the teams' non-technical skills. A paired-sample t-test was used to assess the impact of the intervention on the anaesthesia teams' scores on the various ANTS categories. Interrater agreement between the two ANTS raters was assessed using weighted kappa. At the category level, the overall scores had a statistically significant increase in performance after simulation-based team training (3.48 vs. 3.71; p < 0.001). Furthermore, scores of five of the 15 elements were significantly different. Interrater agreement revealed moderate agreement between the two raters (weighted kappa = 0.51, p value <0.001). The anaesthesia teams' increased non-technical skills after simulation-based team training may indicate the transfer of knowledge from training to clinical practice. The moderate agreement between the raters could be attributed to the subjective nature of the evaluation procedure. The ANTS was originally used as an individual assessment tool; however, this study has demonstrated its potential as a team assessment tool.

Patient knowledge in anaesthesia: Psychometric development of the RAKQ-The Rotterdam anaesthesia Knowledge questionnaire.

The transition from in-person to digital preoperative patient education requires effective methods for evaluating patients' understanding of the perioperative process, risks, and instructions to ensure informed consent. A knowledge questionnaire covering different anaesthesia techniques and instructions could fulfil this need. We constructed a set of items covering common anaesthesia techniques requiring informed consent and developed the Rotterdam Anaesthesia Knowledge Questionnaire (RAKQ) using a structured approach and Item Response Theory. A team of anaesthetists and educational experts developed the initial set of 60 multiple-choice items, ensuring content and face validity. Next, based on exploratory factor analysis, we identified seven domains: General Anaesthesia-I (regarding what to expect), General Anaesthesia-II (regarding the risks), Spinal Anaesthesia, Epidural Anaesthesia, Regional Anaesthesia, Procedural sedation and analgesia, and Generic Items. This itemset was filled out by 577 patients in the Erasmus MC, Rotterdam, and Albert Schweitzer Hospital, Dordrecht, the Netherlands. Based on factor loadings (≥0.25) and considering clinical relevance this initial item set was reduced to 50 items, distributed over the seven domains. Each domain was processed to produce a separate questionnaire. Through an iterative process of item selection to ensure that the questionnaires met the criteria for Item Response Theory modelling, 40 items remained in the definitive set of seven questionnaires. Finally, we developed an Item Response Theory model for each questionnaire and evaluated its reliability. 1-PL and 2-PL models were chosen based on best model fit. No item misfit (S-χ2, p<0.001 = misfit) was detected in the final models. The newly developed RAKQ allows practitioners to assess their patients' knowledge before consultation to better address knowledge gaps during consultation. Moreover, they can decide whether the level of knowledge is sufficient to obtain digital informed consent without face-to-face education. Researchers can use the RAKQ to compare new methods of patient education with traditional methods.

Laparoscopic cholecystectomy in Situs inversus totalis: a case report

Background: Situs inversus totalis (SIT) is a rare congenital condition characterized by the mirror-image reversal of the thoracic and abdominal organs. SIT presents significant challenges during surgical procedures that require anatomical familiarity and dexterity, such as laparoscopic cholecystectomy. Case Presentation: A 73-year-old woman with SIT presented with a 2-day history of left-sided hypochondrial colicky abdominal pain aggravated by food intake and associated with nausea. Physical examination revealed a positive Murphy&amp;apos;s sign in the left hypochondrium. Laboratory tests showed leukocytosis and elevated liver enzymes. Imaging (See Figures 1-4) confirmed acute cholecystitis with the gallbladder in the left upper quadrant. The patient was scheduled for laparoscopic cholecystectomy. Preoperative planning involved detailed imaging and coordination with the anesthesiology team. The surgical technique was adapted for SIT, including specific patient positioning and a mirror-image approach. The gallbladder was successfully removed, with careful dissection of the cystic duct and artery. Postoperative management included non-steroidal anti-inflammatory drugs, opioids, and monitoring. The patient&amp;apos;s recovery was uneventful, and she was discharged on the third postoperative day with follow-up instructions. The care plan included pain management, regular monitoring, early mobilization, diet progression, and scheduled outpatient visits. Conclusion: Laparoscopic cholecystectomy in patients with SIT requires careful preoperative planning, skilled surgical techniques, and effective team communication. Despite these challenges, successful outcomes are possible with meticulous attention to detail and adaptation to the reversed anatomy.
