UNASSIGNED: Numerous pedagogical practices ought to be contemplated for the acquisition of practical aptitudes imperative to postgraduate operating room nursing education. The employment of digital technologies has emerged as a strategic focus in higher education and learning paths exhibit potential as a digital approach in nursing education.
UNASSIGNED: This study aimed to investigate the experiences of postgraduate OR nursing students who underwent a blended learning approach, which combines digital learning paths with skills training, and to explore how this approach prepares students to attain specific learning outcomes during their internship period.
UNASSIGNED: This qualitative study employed a descriptive, exploratory design and utilized focus group interviews facilitated by an interview guide to gather qualitative data. A purposive sampling strategy was employed, and the collected data were analyzed using a systematic text condensation approach.
UNASSIGNED: The analysis of the data revealed two main categories and five subgroups. The first category, \"Blended learning serves as adequate preparation for internship,\" includes subgroups that highlight the advantages of diverse learning activities that aid in the development of a strong foundation in practical skills. The positive influence of peer collaboration fosters improved learning through social interaction, while the organization of the curriculum has a significant impact on students\' learning experiences. The second category, \"The importance of skills training and behaving in an operating theater context,\" consists of subgroups that emphasize the necessity of progressing from basic technical skills training to simulation pedagogy to ensure appropriate behavior in the operating room. Small group sizes, close monitoring, and assessment by educators contribute to effective learning.
UNASSIGNED: The integration of digital learning paths with skills training fosters a problem-solving approach and encourages active and collaborative learning. Skills training in small groups, timely feedback, and coordination among subject managers to handle the students\' workload can create an optimal learning environment.

UNASSIGNED: When applying lung-protective ventilation, fluid responsiveness cannot be predicted by pulse pressure variation (PPV) or stroke volume variation (SVV). Functional hemodynamic testing may help address this limitation. This study examined whether changes in dynamic indices such as PPV and SVV, induced by tidal volume challenge (TVC), can reliably predict fluid responsiveness in patients undergoing renal transplantation who receive lung-protective ventilation.
UNASSIGNED: This nonrandomized interventional study included renal transplant recipients with end-stage renal disease. Patients received ventilation with a 6 mL/kg tidal volume (TV), and the FloTrac system was attached for continuous hemodynamic monitoring. Participants were classified as responders or nonresponders based on whether fluid challenge increased the stroke volume index by more than 10%.
UNASSIGNED: The analysis included 36 patients, of whom 19 (52.8%) were responders and 17 (47.2%) were nonresponders. Among responders, the mean ΔPPV6-8 (calculated as PPV at a TV of 8 mL/kg predicted body weight [PBW] minus that at 6 mL/kg PBW) was 3.32±0.75 and ΔSVV6-8 was 2.58±0.77, compared to 0.82±0.53 and 0.70±0.92 for nonresponders, respectively. ΔPPV6-8 exhibited an area under the curve (AUC) of 0.97 (95% confidence interval [CI], 0.93-1.00; P≤0.001), with an optimal cutoff value of 1.5, sensitivity of 94.7%, and specificity of 94.1%. ΔSVV6-8 displayed an AUC of 0.93 (95% CI, 0.84-1.00; P≤0.001) at the same cutoff value of 1.5, with a sensitivity of 94.7% and a specificity of 76.5%.
UNASSIGNED: TVC-induced changes in PPV and SVV are predictive of fluid responsiveness in renal transplant recipients who receive intraoperative lung-protective ventilation.

This study focuses on understanding the influence of cognitive biases in the intra-operative decision-making process within cardiac surgery teams, recognizing the complexity and high-stakes nature of such environments. We aimed to investigate the perceived prevalence and impact of cognitive biases among cardiac surgery teams, and how these biases may affect intraoperative decisions and patient safety and outcomes. A mixed-methods approach was utilized, combining quantitative ratings across 32 different cognitive biases (0 to 100 visual analogue scale), regarding their \"likelihood of occurring\" and \"potential for patient harm\" during the intraoperative phase of cardiac surgery. Based on these ratings, we collected qualitative insights on the most-rated cognitive biases from semi-structured interviews with surgeons, anaesthesiologists, and perfusionists who work in a cardiac operating room. A total of 16 participants, including cardiac surgery researchers and clinicians, took part in the study. We found a significant presence of cognitive biases, particularly confirmation bias and overconfidence, which influenced decision-making processes and had the potential for patient harm. Of 32 cognitive biases, 6 were rated above the 75th percentile for both criteria (potential for patient harm, likelihood of occurring). Our preliminary findings provide a first step toward a deeper understanding of the complex cognitive mechanisms that underlie clinical reasoning and decision-making in the operating room. Future studies should further explore this topic, especially the relationship between the occurrence of intraoperative cognitive biases and postoperative surgical outcomes. Additionally, the impact of metacognition strategies (e.g. debiasing training) on reducing the impact of cognitive bias and improving intraoperative performance should also be investigated.

The introduction of new technologies in current digestive surgical practice is progressively reshaping the operating room, defining the fourth surgical revolution. The implementation of black boxes and control towers aims at streamlining workflow and reducing surgical error by early identification and analysis, while augmented reality and artificial intelligence augment surgeons\' perceptual and technical skills by superimposing three-dimensional models to real-time surgical images. Moreover, the operating room architecture is transitioning toward an integrated digital environment to improve efficiency and, ultimately, patients\' outcomes. This narrative review describes the most recent evidence regarding the role of these technologies in transforming the current digestive surgical practice, underlining their potential benefits and drawbacks in terms of efficiency and patients\' outcomes, as an attempt to foresee the digestive surgical practice of tomorrow.

UNASSIGNED: The damage that may be caused to the operating table and patients under general anaesthesia when a large earthquake occurs is unclear. We aimed to evaluate the movement and damage to operating tables and patients under general anaesthesia during an earthquake.
UNASSIGNED: An operating table with a manikin resembling a patient on it was placed on a shaking table, and seismic waves were input into the shaking table. The effects of seismic waves were evaluated by altering surgical positions (supine and head-down positions), operating tables, flooring material, seismic waves, and output. We observed the movement of the operating table and measured the acceleration of the operating table and manikin head.
UNASSIGNED: Under 90% output of long-period seismic waves, the operating table with the supine manikin was overturned. Under experimental conditions that did not cause rocking, shaking such as tilting of the operating table caused stronger acceleration in the manikin\'s head than in the operating table. There was no clear relationship between operating table rocking and maximum acceleration as a result of programmed seismic waves. In long-period earthquakes, rocking and overturning occurred >60 s after the onset of shaking, whereas in direct earthquakes, rocking occurred within 10 s.
UNASSIGNED: An earthquake could cause strong acceleration of the patient\'s head under general anaesthesia, and operating tables may overturn or shake violently. Regarding patient safety, further measures to prevent overturning should be considered.

BACKGROUND: Clinical care pathways help guide and provide structure to clinicians and providers to improve healthcare delivery and quality. The Quality Improvement and Patient Safety Committee (QIPS) of the American Society for Metabolic and Bariatric Surgery (ASMBS) has previously published care pathways for the performance of laparoscopic sleeve gastrectomy (LSG) and pre-operative care of patients undergoing Roux-en-Y gastric bypass (RYGB).
OBJECTIVE: This current RYGB care pathway was created to address intraoperative care, defined as care occurring on the day of surgery from the preoperative holding area, through the operating room, and into the postanesthesia care unit (PACU).
METHODS: PubMed queries were performed from January 2001 to December 2019 and reviewed according to Level of Evidence regarding specific key questions developed by the committee.
RESULTS: Evidence-based recommendations are made for care of patients undergoing RYGB including the pre-operative holding area, intra-operative management and performance of RYGB, and concurrent procedures.
CONCLUSIONS: This document may provide guidance based on recent evidence to bariatric surgeons and providers for the intra-operative care for minimally invasive RYGB.

OBJECTIVE: This study explores student nurse anesthetists\' (SNAs) learning in the operating room during the coronavirus 2019 pandemic.
METHODS: An explorative design with semistructured interviews was used.
METHODS: Thirteen former SNAs and 12 clinical supervisors (8 of whom were included in the final analysis) were recruited from 6 counties in Sweden. Participants were purposively recruited. Inclusion criterion for former SNAs was having completed the nurse anesthesia program in the fall of 2020 to spring 2022; and for nurse anesthetists, those who have experience in supervising SNAs. The interviews were analyzed with thematic analysis.
RESULTS: The analysis identified one theme and five subthemes. The theme was that student learning was in focus despite an ongoing pandemic. Every learning situation contributed, and learning was triggered by the challenges. Both the SNAs and the supervisors exhibited resilience by accepting the situation and striving to do their absolute best in a nonoptimal learning environment. Over time, learning and supervision returned to normal.
CONCLUSIONS: During the pandemic, learning was ongoing despite stress, fear, and other challenging factors. Students\' learning appears to have been prioritized. The study highlights that nurse anesthetists and SNAs were resilient, resourceful, and able to find new ways to keep learning going.

UNASSIGNED: The conventional round suture needle poses a significant risk of needle stick injuries among surgical physicians, identified as a global occupational hazard by the World Health Organization, increasing hospital costs and exposure to bloodborne pathogens. While novel blunt suture needles have shown promise in reducing these risks, their adoption is limited domestically, prompting a study to compare their efficacy against traditional sharp needles in reducing needle stick injuries among surgical physicians.
UNASSIGNED: To investigate suture needle stick injuries among surgical doctors during operations and assess the application effectiveness of a novel blunt suture needle.
UNASSIGNED: A total of 106 surgical department physicians from March 2021 to February 2023 participated in the study. After completing a questionnaire survey on suture needle injuries during surgery, the participants were divided into two groups. Over a 6-month intervention period, the control group used regular round needles while the study group utilized novel blunt suture needles. Subsequently, suture needle injury incidence rates and economic hygiene benefits were compared between the two groups.
UNASSIGNED: The suture needle injury questionnaire survey showed that over the past 6 months, among 106 surgical department physicians, 20 needle stick injuries occurred, yielding an incidence rate of 18.87%. The highest incidence (65.00%) was during suturing incisions longer than 10 cm, primarily when visibility was poor (70.00%). Surgeons linked most injuries (60.00%) to prolonged surgical duration causing fatigue. Although 85.00% detected injuries within 1 minute, only 40.00% were reported, often due to perceived reporting complexity. Following intervention, the study group had significantly fewer injuries per surgery and lower occupational exposure costs compared to the control group (p< 0.05).
UNASSIGNED: Surgical department physicians commonly sustain suture needle injuries while suturing incisions of 5-10 cm length under poor visibility, exacerbated by prolonged surgical duration. Despite detecting most injuries within 1 minute, only 40% are reported. The implementation of novel blunt suture needles significantly decreases injury rates, resulting in reduced occupational exposure costs and favorable safety and economic hygiene outcomes.

UNASSIGNED: The study aimed to fill the knowledge gap about how operating room (OR) design could reduce orthopedic surgery duration and contribute to surgical care safety and efficiency.
UNASSIGNED: Long surgery duration may lead to delays and cancellations of surgeries, deteriorated patient experiences, postoperative complications, and waste of healthcare resources. The OR physical environment may contribute to the reduction of surgery duration by minimizing workflow disruptions and personnel movements during surgeries.
UNASSIGNED: Unobtrusive observations were conducted of 70 unilateral total knee or hip replacement surgeries in two differently designed ORs at a community hospital in the United States. A set of computer-based forms adapted from recent research was used to measure the surgery duration, environment-related disruptions, and ambulatory movements involving circulators. Potential confounding factors like surgery type were controlled in statistical analyses.
UNASSIGNED: Significantly shorter surgery durations were recorded in the larger OR with more clearances on both sides of the operating table, a wider door located on the sidewall, more cabinets, and more clearance between the circulator workstation and the sterile field (p =.019). The better-designed OR was also associated with less frequent disruptions and fewer movements per case (p < .001). Significant correlations existed between surgery duration, the number of disruptions, and the number of movements (rs = .576-.700, ps < .001).
UNASSIGNED: The study demonstrated the important role of OR physical environment in supporting the safe and efficient delivery of surgical care, which should be further enhanced through research and design innovations.

BACKGROUND: Head and neck oncologic resections with microvascular reconstruction are lengthy and complex procedures with inefficiencies in the operating room (OR) associated with increased complications and higher costs. Multidisciplinary care has become increasingly used to provide improved care for complex patients; however, the potential role of this has not yet been studied in head and neck microvascular free flap procedures.
METHODS: Patients between 2016 and 2022 treated before and after implementation of the conference were included. Primary outcome was total procedure time (TPT). Demographics, operative details, and postoperative complications were also collected.
RESULTS: 233 patients were included in the preconference group and 330 in the post-conference group. Preconference mean (SD) age was 61.6 (12) years versus 62.9 (12) years in the post-conference group. The post-conference group was associated with shorter mean (SD) TPT (629 [117] vs. 719 [134] minutes), less mean (SD) estimated blood loss (ESD) (230 [201] mL vs. 306 [211] mL), fewer prolonged lCU stays (>1 day), and fewer returns to the operating room (RTOR). The post-conference group was associated with TPT ≤9 h (p < 0.001) on multivariate analysis. Factors associated with TPT greater than 9 h include history of head and neck radiation (p = 0.003), bony reconstruction (p = 0.05), stage IVa (p = 0.009), and stage IVb cancer (p < 0.001).
CONCLUSIONS: Implementation of the multidisciplinary conference in head and neck surgery was associated with reduced TPT and reduced OR return. Our study suggests preoperative planning conferences may improve surgical efficiency and outcomes in head and neck oncologic resections with microvascular free flap reconstruction.
