Videolaryngoscopy vs. direct laryngoscopy use by experienced anaesthetists in patients with known difficult airways: a systematic review and meta-analysis.

Experienced anaesthetists can be confronted with difficult or failed tracheal intubations. We performed a systematic review and meta-analysis to ascertain if the literature indicated if videolaryngoscopy conferred an advantage when used by experienced anaesthetists managing patients with a known difficult airway. We searched PubMed, MEDLINE, Embase and the Cochrane central register of controlled trials up to 1 January 2017. Outcome parameters extracted from studies were: first-attempt success of tracheal intubation; time to successful intubation; number of intubation attempts; Cormack and Lehane grade; use of airway adjuncts (e.g. stylet, gum elastic bougie); and complications (e.g. mucosal and dental trauma). Nine studies, including 1329 patients, fulfilled the inclusion criteria. First-attempt success was greater for all videolaryngoscopes (OR 0.34 (95%CI 0.18-0.66); p = 0.001). Use of videolaryngoscopy was associated with a significantly better view of the glottis (Cormack and Lehane grades 1 and 2 vs. 3-4, OR 0.04 (95%CI 0.01-0.15); p < 0.00001). Mucosal trauma occurred less with the use of videolaryngoscopy (OR 0.16 (95%CI 0.04-0.75); p = 0.02). Videolaryngoscopy has added value for the experienced anaesthetist, improving first-time success, the view of the glottis and reducing mucosal trauma.

European Society of Gastrointestinal Endoscopy, European Society of Gastroenterology and Endoscopy Nurses and Associates, and the European Society of Anaesthesiology Guideline: Non-anesthesiologist administration of propofol for GI endoscopy.

Propofol sedation by non-anesthesiologists is an upcoming sedation regimen in several countries throughout Europe. Numerous studies have shown the efficacy and safety of this sedation regimen in gastrointestinal endoscopy. Nevertheless, this issue remains highly controversial. The aim of this evidence- and consensus-based set of guideline is to provide non-anesthesiologists with a comprehensive framework for propofol sedation during digestive endoscopy. This guideline results from a collaborative effort from representatives of the European Society of Gastrointestinal Endoscopy (ESGE), the European Society of Gastroenterology and Endoscopy Nurses and Associates (ESGENA) and the European Society of Anaesthesiology (ESA). These three societies have endorsed the present guideline.

Personality dimensions and their relationship with job satisfaction amongst Dutch nurse anaesthetists.

AIM: This study investigates the relationship between personality dimensions and job satisfaction. BACKGROUND: The shortage of nurses, and those voluntarily leaving their jobs, continues to be a problem affecting the delivery of healthcare all over the world, including anaesthesia. If it is found that nurse anaesthetists with certain personality types have high levels of job satisfaction, the information may be helpful for the retention of nurse anaesthetists. METHODS: A questionnaire was distributed amongst Dutch nurse anaesthetists. Factor and multiple regression analyses were performed to reveal personality dimensions and their impact on job satisfaction. RESULTS: Nine hundred and twenty-three questionnaires were completed and analysed (46% response rate). Two personality dimensions -'easy going' and 'orderly'- explained 3.5% of the variance in job satisfaction. CONCLUSION: Personality dimensions as measured with the Myers-Briggs Type Indicator (MBTI) are only minimally relevant in predicting job satisfaction amongst Dutch nurse anaesthetists. IMPLICATIONS FOR NURSING MANAGEMENT: Before using personality traits as a selection tool for retaining employees, it is important to understand the relationship of particular personalities to job satisfaction; it is also important to know which combination of personality traits is likely to create a highly cohesive work group.

Exogenous application of platelet-leukocyte gel during open subacromial decompression contributes to improved patient outcome. A prospective randomized double-blind study.

BACKGROUND: Platelet-leukocyte gel (PLG) is being used during various surgical procedures in an attempt to enhance the healing process. We studied the effects of PLG on postoperative recovery of patients undergoing open subacromial decompression (OSD). METHODS: PLG was produced from platelet-leukocyte-rich plasma (P-LRP), prepared from a unit of whole blood. Forty patients were included in the study. Self-assessed evaluations, using the American Shoulder and Elbow Surgeons scoring system of activities of daily living (ADL), joint instability, pain levels, pain medications, and clinical evaluations for range of motion were conducted. RESULTS: Platelet and leukocyte counts were significantly increased in the P-LRP compared to baseline counts. Treated patients demonstrated decreased visual analog scales for pain and used significantly less pain medication, had an improved range of motion during passive forward elevation, external rotation, external rotation with arm at 90 degrees abduction, internal rotation, and cross body adduction compared to control patients (p < 0.001). No differences in the instability score were observed between the groups. Furthermore, treated patients performed more ADL (p < 0.05). CONCLUSION: In the PLG-treated group, recovery was faster and patients returned earlier to daily activities and also took less pain medication than control subjects.

Reviewing the structural features of autologous platelet-leukocyte gel and suggestions for use in surgery.

The therapeutic use of autologously prepared platelet-leukocyte gel (PLG) is a relatively new technology which might stimulate and accelerate soft-tissue and bone healing. The effectiveness of this procedure lies in the exogenous delivery of a wide range of platelet growth factors, intentionally released from autologously prepared PLG. The rationale to employ this technique is to mimic physiological wound healing and reparative tissue processes. Despite an increase in clinical PLG applications, the structures and kinetics of this biological material have not been completely examined. Electron microscopic imaging was performed to evaluate platelet-leukocyte gel structures. Furthermore, directions for PLG application are presented, based on results from published articles in various surgical disciplines. In conclusion, PLG can be useful in a wide range of clinical applications to enhance healing following surgical procedures, since exogenous applied PLG releases instantly platelet growth factors, in the presence of leukocytic cells.

Moderate-to-deep sedation technique, using propofol and ketamine, allowing synchronised breathing for magnetic resonance high-intensity focused ultrasound (MR-HIFU) treatment for uterine fibroids: a pilot study.

BACKGROUND: Magnetic resonance high-intensity focused ultrasound (MR-HIFU) treatment for uterine fibroids is rapidly gaining popularity as a treatment modality. This procedure is generally uncomfortable, painful, and requires minimal or absence of movement and an MR-HIFU synchronised breathing pattern of the patient. Procedural sedation and analgesia protocols have become the standard practice in interventional radiology departments worldwide. The aim of this study was to explore if a sedation regimen with low-dose propofol and ketamine performed by trained non-medical sedation practitioners could result in relief of discomfort for the patient and in adequate working conditions for MR-HIFU treatment for uterine fibroids. METHODS: In this study, conducted from August 2013 until November 2014, 20 patients were subjected to MR-HIFU treatment of uterine fibroids. Patients were deeply sedated using intravenous propofol and esketamine according to a standardised hospital protocol to allow synchronisation of the breathing pattern to the MR-HIFU. The quality of sedation for MR-HIFU and complications were recorded and analysed. The side effects of the sedation technique, the propofol and esketamine consumption rate, the duration of recovery, and patient satisfaction after 24 h were examined. RESULTS: A total of 20 female patients (mean age 42.4 [range 32-53] years) were enrolled. Mean propofol/esketamine dose was 1309 mg/39.5 mg (range 692-1970 mg/ 23.6-87.9 mg). Mean procedure time was 269 min (range 140-295 min). Application of the sedation protocol resulted in a regular breathing pattern, which could be synchronised with the MR-HIFU procedures without delay. The required treatment was completed in all cases. There were no major adverse events. Hypoxemia (oxygen desaturation <92%) and hallucinations were not observed. CONCLUSIONS: The use of a specific combination of IV propofol and esketamine for procedural sedation and analgesia reduced the discomfort and pain during MR-guided HIFU treatments of uterine fibroids. The resulting regular breathing pattern allowed for easy synchronisation of the MR-HIFU procedure. Based on our results, esketamine and propofol sedation performed by trained non-medical sedation practitioners is feasible and safe, has a low risk of major adverse events, and has a short recovery time, avoiding a session of general anaesthesia.

[Nitrous oxide not unsafe but used less often]. / Lachgas niet onveilig, maar wel steeds minder nodig.

In the Netherlands and elsewhere there is ongoing debate about the potential of nitrous oxide (used as a medical gas for more than 150 years), to cause spontaneous abortion, malignancies and renal and hepatic disease in health-care workers. Although nitrous oxide has been shown to have teratogenic properties in rodents, there is no evidence for such an effect in humans. The number of indications for the application of nitrous oxide in the Netherlands are diminishing. Therefore it is proposed to use nitrous oxide on strict indication only, and to strictly adhere to policies to reduce exposure to the drug for health-care workers.

[Tracheal rupture as a cause of unanticipated perioperative mortality]. / Trachearuptuur als oorzaak van onverwacht peroperatief overlijden.

Here we report two cases in which healthy young patients died during surgery because ventilation was impossible by a clinical picture of massive subcutaneous emphysema. The probable diagnosis was tracheal rupture. This diagnosis was not confirmed during coroner's autopsy, but there had been no systematic search for a puncture in the trachea or the main bronchial tubes. Immediate recognition of this situation, and implementation of ventilation of one lung by pushing a narrower endobronchial tube beyond the tracheal rupture, is potentially life-saving.

Adherence to safety guidelines on paediatric procedural sedation: the results of a nationwide survey under general paediatricians in The Netherlands.

OBJECTIVES: Following two fatal accidents during paediatric procedural sedation (PS), the authors investigated the level of adherence to established safety standards on PS in a nationwide cohort of fully trained general paediatricians, entrusted with PS. STUDY DESIGN AND METHODS: Sample survey Safety guidelines on PS were split into four domains ("Presedation Assessment", "Monitoring during PS", "Recovery after PS" and "Facilities and Competences for Emergencies and Rescue"). Each domain was operationalised into sub-domains and items. Items were presented within a questionnaire list as procedural points of attention on which respondents could give their personal adherence score. Percentages of full adherence were calculated. Non-adherence was defined as gradual deviation from full adherence. After factor and reliability analysis, observed scores were summed up to scales, and results were transformed to a 0-10 report mark (RM). An RM of ≥9 is considered as a satisfactory level of adherence while an RM <6 is considered as unacceptably low. RESULTS: Full adherence was rare. For most (sub) domains, only a minority of respondents achieved a satisfactory level of adherence. Large numbers of respondents had scores below 6. CONCLUSIONS: Potentially unsafe PS practices are common under Dutch general paediatricians, despite the availability of guidelines. The design of guidelines should include a goal-directed plan for implementation including training, initiatives for continuous quality assurance and improvement and repeated measurements of adherence to guidelines.

Core curriculum in emergency medicine integrated in the specialty of anaesthesiology.

Anaesthesiologists, for their knowledge, skills and expertise, have been playing a key role in the development of emergency medicine. In many countries, anaesthesiologists are today fully involved in teaching and practicing emergency medicine, and have leading roles in emergency departments. Proper education and effective interdisciplinary medical cooperation is essential for quality assurance in emergency medicine. This paper, produced by a working party of the European Board of Anaesthesiology of the European Union of Medical Specialists (EUMS/UEMS), gives directions for a core curriculum in emergency medicine integrated in the specialty of anaesthesiology.

Charter on continuing medical education/continuing professional development approved by the UEMS Specialist Section and European Board of Anaesthesiology.

The mission of the Section and Board of Anaesthesiology of the European Union of Medical Specialists (EUMS/UEMS) is to harmonize training and medical practice in all European countries to continuously improve the quality of care. The need for continuous medical education in the field of anaesthesiology has long been recognized. However, specialty-based competencies are not the only requirements for successful medical practice. The need to acquire medical, managerial, ethical, social and personal communication skills on top of specialty-based competencies has developed into the principle of continuous professional development, which embraces both objectives. The Section and Board of Anaesthesiology of the EUMS/UEMS has approved a proposal of its Standing Committee on Continuous Medical Education/Continuous Professional Development to adopt the following charter on the subject.

Guidelines for safety and quality in anaesthesia practice in the European Union.

Anaesthesia is a medical specialty that is particularly concerned with the safety of the patient who is undergoing a surgical procedure. This is a prerequisite in order to provide quality of care, which is based on good clinical practice, on a sound organization, on an agreement on best practice and on adequate communication with other healthcare workers involved. Providing a safe environment for those working in healthcare is at least as important as other factors serving that objective. A working party on Safety and Quality in Anaesthesiological Practice in the Section and Board of Anaesthesiology of the European Union of Medical Specialists (EUMS/UEMS) has prepared guidelines that were amended and approved recently.

Guidelines for sedation and/or analgesia by non-anaesthesiology doctors.

The still ever increasing demand for sedation and/or analgesia for diagnostic and therapeutic procedures puts high pressure on anaesthesia care providers all over Europe. Since the capacity to provide that service by anaesthetists is limited in most European countries, guidelines for non-anaesthetist doctors who want to sedate patients on a high-quality level and especially in a safe way are mandatory. This paper, produced by a working party of the European Board of Anaesthesiology of the European Union of Medical Specialists (EUMS/UEMS), gives direction to those practitioners who feel responsibilities in this area of medicine. Close cooperation with anaesthesiologists seems mandatory to achieve and sustain a high-quality standard for our patients undergoing medical or surgical procedures under sedation.

Guidelines for anaesthesiologist specialist training in pain medicine.

The Section and Board of Anaesthesiology of the European Union of Medical Specialists aims (EUMS/UEMS) at harmonization of training of anaesthesiologists and at improvement of patient care throughout Europe. Pain medicine is considered to be an area of expertise in anaesthesiology although exclusivity is not claimed. The Section and Board has approved both a core syllabus for pain medicine to be part of the specialist training in anaesthesiology and an additional qualification in pain medicine following the completion of a 5 yr basic specialty training in anaesthesiology. These proposals were prepared by the Working Party on Pain Medicine of the Section and Board. It considers a multidisciplinary approach to pain to contribute to quality in care and has taken the initiative to set up a Multidisciplinary Joint Committee on Pain Medicine within the EUMS/UEMS, for which these guidelines define the area of expertise of anaesthesiology.

How to inform a morbidly obese patient on the specific risk to develop postoperative pulmonary complications using evidence-based methodology.

BACKGROUND AND OBJECTIVE: Patients have the right to be informed about the expected benefits and risks of medical and surgical procedures. Ideally this information should be scientifically based and presented to the patient in time. In morbidly obese patient undergoing general anaesthesia, postoperative pulmonary complications are an important cause of postoperative morbidity and mortality. A 46-yr-old female with a body mass index of 89.8 kg m(-2) was scheduled to undergo radical abdominal surgery for cervix carcinoma. In order to inform her accurately on the risk of developing postoperative pulmonary complications, we undertook to answer the following question: What is the risk to develop postoperative pulmonary complications in a morbidly obese patient about to undergo abdominal surgery under general anaesthesia? METHODS: A Medline search was conducted from 1966 to 2004 with respect to postoperative pulmonary complications in abdominal surgery of morbidly obese patients. Altogether, 213 articles were found, of which seven were selected. Additionally, seven cross-references and or related articles were used. RESULTS: For obese patients who undergo abdominal surgery under general anaesthesia, the likelihood to develop atelectasis is 10.4 +/- 4.8% (P < 0.001) with a correlation coefficient of 0.28-0.34 (P < 0.05). The likelihood to develop atelectasis and pneumonia taken together is 29.3% with an adjusted odds ratio of 2.82 (95% confidence interval 1.66-4.78; P = 0.0001). CONCLUSION: Considering the positive correlation coefficient and the high body mass index of this patient she has a risk of at least 29.3% to develop pneumonia and/or atelectasis, which should affect the anaesthetic strategy in this patient.

Platelet gel and fibrin sealant reduce allogeneic blood transfusions in total knee arthroplasty.

BACKGROUND: Total knee arthroplasty (TKA) is often associated with a considerable amount of post-operative blood loss, necessitating the transfusion of allogeneic blood, which can add to the complications. Optimization of strategies to reduce the need for blood transfusion is desired. This study was designed to evaluate the efficacy of autologous platelet gel and fibrin sealant in unilateral TKA. METHODS: Consecutive patients were operated on and assigned to the study and control groups. Study group patients (n = 85) were operated on according to our standard TKA protocol, with the application of autologous platelet gel and fibrin sealant on the wound tissues at the end of surgery. Eighty patients were operated on according to the same protocol, but without the use of platelet gel and fibrin sealant, and served as the control group. All blood transfusions, occurrence of wound leakage, wound healing disturbances and incidences of post-operative infections were recorded. RESULTS: Patients in the treatment group had a significantly higher post-operative haemoglobin level (11.3 vs. 8.9 g/dl, respectively) and a decreased need for allogeneic blood products (0.17 vs. 0.52 units, respectively) than those in the control group (P < 0.001). The incidences of wound leakage and wound healing disturbance were significantly less (P < 0.001) in patients managed with platelet gel and fibrin sealant. Four patients in the control group, who received blood products, developed wound infection. The hospital stay was decreased by 1.4 +/- 1.5 days for patients in the treatment group (P < 0.001). CONCLUSION: Peri-operatively applied platelet gel and fibrin sealant may reduce the incidence of allogeneic blood transfusions and complications associated with TKA.
