The current literature indicates that routine evaluation of preoperative anxiety, its determinants, and patient-specific concerns is universally advocated. This aligns with the increasingly acknowledged importance of prehabilitation - a comprehensive process preparing patients for surgery. A crucial component of prehabilitation is assessing patients' mental health. Recommendations for psychological evaluations in prehabilitation encompass, inter alia, determining the severity of anxiety. This work builds on a 2019 article, which presented scales for preoperative anxiety assessment: the State Trait Anxiety Inventory (STAI), the Hospital Anxiety and Depression Scale (HADS), the Amsterdam Preoperative Anxiety and Information Scale (APAIS), and the Visual Analogue Scale (VAS). This article extends the possibilities of preoperative anxiety assessment by introducing four additional methods: the Surgical Fear Questionnaire (SFQ), the Anxiety Specific to Surgery Questionnaire (ASSQ), the Surgical Anxiety Questionnaire (SAQ), and Anesthesia- and Surgery-dependent Preoperative Anxiety (ASPA). The authors provide comprehensive details on these instruments, including scoring, interpretation, availability, and usefulness both in scientific research and clinical practice. The authors also provide the data on the availability of Polish versions of the presented methods and preliminary data on the reliability of SFQ in patients awaiting cardiac surgery. This review seems relevant for professionals in multiple disciplines, including anesthesiology, surgery, clinical psychology, nursing, primary care and notably prehabilitation. It emphasizes the necessity of individualizing anxiety assessment and acknowledging patient subjectivity, which the presented methods facilitate through a thorough evaluation of specific patient concerns. The literature review also identifies concerns and future research avenues in this area. The importance of qualitative studies and those evaluating prehabilitation intervention is emphasized.

Introduction: The significant effect of deep neuromuscular block (NMB) in laparoscopic surgery is still controversial, especially in lower-pressure pneumoperitoneum. This study investigates the effect of deep neuromuscular block on intraabdominal pressure (IAP), surgical space quality, post-operative abdominal pain, and shoulder tip pain in laparoscopic gynaecological surgery.
Material and methods: This is a randomised, double-blinded control trial which randomised samples to moderate NMB (train-of-four count [TOF] of 1 or 2) or deep NMB (post-tetanic count [PTC] of 1 or 2). Surgery began with IAP 8 mmHg but was allowed to increase the pressure if the surgical condition was unfavourable. The surgical condition was rated on a 4-point scale. Post-operative abdominal pain and shoulder tip pain was assessed using a numerical rating scale for pain, with 0 defined as no pain and 10 severe pain at recovery area (time 0), 30 minutes, and 24 hours post-operation.
Results: Seventy patients completed the study. The rate of increasing IAP between the 2 groups ( P = 0.172) is not significant, but deep NMB requires less pressure - mean highest IAP of 10.31 (± 1.39) mmHg, moderate NMB 11.54 (± 1.69) mmHg. The mean surgical space condition score was significantly better in the deep NMB group at 2.4 (± 0.7) compared to moderate NMB at 3.2 (± 0.66), P < 0.005. There was a significantly lower post-operative abdominal pain score in deep NMB but no significant difference in shoulder tip pain score between the 2 groups.
Conclusions: Deep NMB enables the usage of lower IAP in laparoscopic surgery without interfering with surgical space condition, and it reduces the post-operative abdominal pain score in 24 hours compared to moderate NMB.

Background: Guidelines and consensus statements recommend the use of videola-ryngoscopes (VLs) in airway management of patients with COVID-19. However, there is a lack of knowledge about which types of videolaryngoscopes are used, differences of use between countries, and how the COVID-19 pandemic influenced their use. The primary aim of this before-and-after cross-sectional survey study was to assess the frequency of the use of videolaryngoscopy in the operation theatres in different countries. Also, the preferred characteristics of videolaryngoscopes were assessed.
Methods: With Ethics Committee approval, a questionnaire was distributed among anaes-thesiologists through the European Airway Management Society's network in 2019 before and in 2021 during the COVID-19 pandemic. Responses to the questions were analysed and presented as descriptive statistics.
Results: We reached out to 791 anaesthesiologists; 155 (19.5%) returned the first questionnaire, and 91 (11.5%) returned the second survey. Videolaryngoscopes were used in 24.1% of cases before COVID-19 and in 43.1% after the pandemic ( P < 0.001). We revealed that the availability of videolaryngoscopes increased to 100% in all centres during the pandemic. Routine use of videolaryngoscopes in all cases increased from 12.5% to 38.9%. The type of videolaryngoscope and the blade preference did not change during this period ( P = 1.000).
Conclusions: This survey reflects that the COVID-19 pandemic significantly increased the availability and use of videolaryngoscopes in operating theatres, and that more anaesthesiologists now use them routinely in all cases. The preferred type of VL or blade did not change during the pandemic.

Introduction: Recent years have seen an increasing number of elective total knee (TKA) and hip arthroplasty (THA) procedures. Since a wide variety of methods and procedures are used in perioperative management, a survey-based study was carried out to identify the patterns of practice in Polish hospitals.
Material and methods: With the help of the LimeSurvey application, questionnaires for anaesthesio-logists and orthopaedists were prepared to gain insight into the preparation of patients for TKA and THA procedures and perioperative care. Questionnaires included both single and multiple-choice questions concerning among other things type of laboratory tests, additional examinations and consultations performed on a routine basis before elective TKA and THA procedures.
Results: A total of 162 medical centres took part in the study. Questionnaire responses were obtained from 93 (57%) orthopaedics teams and 112 (69%) anaesthesiology teams. A mean (standard deviation, SD) of 7.2 (3.5) laboratory tests are routinely ordered before surgery. For example, 47% of orthopaedists and 20% of anaesthesiologists order urinalysis, while 53% of orthopaedists and 26% of anaesthesiologists order a CRP test. Seventy-nine per cent of orthopaedists refer patients for at least one specialist consultation before the procedure. Dental consultation is requested by 40%, gynaecological consultation by 27%. Patient preoperative education is provided by 85% of orthopaedists and preoperative rehabilitation is prescribed by 46% of them. A total of 56% surveyed anaesthesiologists perform pre-anaesthetic evaluation upon patients' hospital admission.
Conclusions: The study found that the number of examinations and specialist consultations conducted in Polish hospitals exceeded the scope of recommendations of scientific societies. Furthermore, the authors identified a need to standardise perioperative management in the form of Polish guidelines or recommendations, with the intention to improve patient safety and optimize health care expenses.
