Project description:BackgroundDuring the COVID-19 pandemic, several questions have arisen about which endoscopic procedures (EPs) must be performed and which ones can be postponed. The aim of this study was to conduct a nationwide survey regarding the appropriate timing of EPs during the COVID-19 pandemic.MethodsThis prospective study was performed through a nationwide electronic survey. The survey consisted of 15 questions divided into three sections. The first evaluated the agreement for EPs classified as "time sensitive" and "not time sensitive". Two other sections assessed "high-priority" and "low-priority" scenarios. Agreement was considered when > 75% of respondents answered a question in the same direction.ResultsThe response rate was 27.2% (214/784). Among the respondents, agreement for the need to perform EP in < 72 h was only reached for variceal bleeding (93.4%). Dysphagia with alarm symptoms was the scenario in which the highest percentage of physicians (95.9%) agreed that an EP needed to be performed within a month. Less than 30% of endoscopists would perform an EP within the first 72 h for patients with mild cholangitis, non-variceal upper gastrointestinal bleeding without hemodynamic instability, or severe anaemia without overt bleeding. In time-sensitive clinical scenarios suggestive of benign disease, none of the scenarios reached agreement in any sense. Among the time-sensitive clinical scenarios suggestive of malignancy, > 90% of the surveyed respondents considered that EP could not be postponed for > 8 weeks.ConclusionsThere was no consensus among endoscopists about the timing of EPs in patients with pathologies considered time sensitive or in those with high-priority pathologies. Agreement was only reached in five (17%) of the evaluated clinical scenarios.

Project description:Background and study aims Unbiased communication is crucial for excellent teamwork in high-quality endoscopy. Personal protective equipment (PPE) (FFP-masks and face-shields) worn by endoscopists that are ubiquitous in the current COVID-19 pandemic strikingly impair communication. Digital enhancement approaches to maintain team communication, especially during complex endoscopic procedures, are urgently warranted. Materials and methods A prospective, two-armed interventional study was performed at an endoscopy unit at a tertiary center in Germany. Two hundred and three endoscopic procedures with PPE se according to pandemic risk level were randomly assigned (1:1) to a group performed by an endoscopy team equipped with digital enhanced cordless telecommunication (DECT) or one without digital-enhanced communication. The primary outcome was the team-reported number of communication-associated events (CAEs) defined as misunderstandings that impaired workflow during endoscopic examination. Secondary outcomes included perceived voice and headphone quality and overall comfort with DECT during endoscopic work. Results The use of DECT was associated with a significant reduction in communication-associated events in endoscopic procedures and overall, was perceived positively. Conclusions Digital enhancement of communication is a promising and easy-to- establish tool for improving team communication quality in endoscopy.

Project description:ObjectiveThe COVID-19 pandemic has precipitated widespread shortages of filtering facepiece respirators (FFRs) and the creation and sharing of proposed substitutes (novel designs, repurposed materials) with limited testing against regulatory standards. We aimed to categorically test the efficacy and fit of potential N95 respirator substitutes using protocols that can be replicated in university laboratories.SettingAcademic medical centre with occupational health-supervised fit testing along with laboratory studies.ParticipantsSeven adult volunteers who passed quantitative fit testing for small-sized (n=2) and regular-sized (n=5) commercial N95 respirators.MethodsFive open-source potential N95 respirator substitutes were evaluated and compared with commercial National Institute for Occupational Safety and Health (NIOSH)-approved N95 respirators as controls. Fit testing using the 7-minute standardised Occupational Safety and Health Administration fit test was performed. In addition, protocols that can be performed in university laboratories for materials testing (filtration efficiency, air resistance and fluid resistance) were developed to evaluate alternate filtration materials.ResultsAmong five open-source, improvised substitutes evaluated in this study, only one (which included a commercial elastomeric mask and commercial HEPA filter) passed a standard quantitative fit test. The four alternative materials evaluated for filtration efficiency (67%-89%) failed to meet the 95% threshold at a face velocity (7.6 cm/s) equivalent to that of a NIOSH particle filtration test for the control N95 FFR. In addition, for all but one material, the small surface area of two 3D-printed substitutes resulted in air resistance that was above the maximum in the NIOSH standard.ConclusionsTesting protocols such as those described here are essential to evaluate proposed improvised respiratory protection substitutes, and our testing platform could be replicated by teams with similar cross-disciplinary research capacity. Healthcare professionals should be cautious of claims associated with improvised respirators when suggested as FFR substitutes.

Project description:Current SARS-CoV-2 coronavirus pandemic is challenging medical and surgical activities. Specifically, within neurosurgery, endoscopic endonasal approaches pose a high risk of contagion for healthcare personnel involved in it. Initially, the recommendation was to avoid such surgeries. However, the pandemic has dragged on and new solutions must be proposed to continue carrying out these approaches safely. Given the lack of established protocols, we propose the following one, which concisely establishes the measures to be taken in both urgent and scheduled surgery. In addition, a new protection-aspiration device (Maskpirator) is described.

Project description:ObjectiveIntroducing a new, simple and inexpensive portable equipment for lifeguards, consisting of a pre-assembled full-size plastic blanket with a mask and HEPA filter, which could offer significant time-saving advantages to reduce COVID-19 risk transmission in the first few minutes of CPR after water rescue, avoiding the negative impact of delayed ventilation.MethodA pilot study was carried out to determine the feasibility of the pre-assembled kit of face-mask and HEPA filter adapted on a pre-set plastic-blanket. The first step consisted of washing hands, putting on safety glasses and gloves as the first personal protection equipment (PPE) and then covering the victim with an assembled plastic blanket. The second step consisted of 10 min of cardiopulmonary resuscitation (CPR) with PPE and plastic blanket, following the technical recommendations for ventilation during COVID-19.ResultsTen rescuers took part in the pilot study. The average time to wear PPE and place the pre-assembly kit on the victim was 82 s [IC 58-105]. After 10 min the quality of the resuscitation (QCPR) was 91% [87-94]. Quality chest compressions (CC) were 22% better than ventilations (V). Most of the rescuers (60%) thought that placing the plastic blanket on the victim on the beach was somewhat simple or very simple.ConclusionsResuscitation techniques in COVID-19 era at the beach have added complexities for the correct use of PPE. Plastic blanket plus basic ventilations equipment resource could be a new alternative to be considered for lifeguards to keep ventilation on use while reducing risk transmission.

Project description:ObjectiveTo create an aerosol containment mask (ACM) that contains aerosols during common otolaryngologic endoscopic procedures while protecting patients from environmental aerosols.Study designBench testing.SettingMannequin testing.MethodsThe mask was designed in SolidWorks and 3-dimensional printed. Mannequins were fitted with a nebulizer to generate aerosols. Commercial particle counters were used to measure mask performance.ResultsThe ACM has 2 ports on either side for instruments and endoscopes, a port for a filter, and a port that can evacuate aerosols contained within the mask via a standard suction pump. The mask contained aerosols on a mannequin with and without facial hair when the suction was set to 18.5 L/min. Other types of masks demonstrated substantial aerosol leakage under similar conditions. In a subsequent experiment, the ACM contained aerosols generated by a nebulizer up to the saturation of the particle detector without measurable leakage with or without suction.ConclusionThe ACM will accommodate rigid and flexible endoscopes plus instruments and prevent leakage of patient-generated aerosols, thus avoiding contamination of the room and protecting health care workers from airborne contagions.Level of evidence2.

Project description:BackgroundDuring the COVID-19 pandemic, disruption of surgical hands-on training has hampered the skills acquisition by budding neurosurgeons. Online and virtual classrooms have not been able to substitute the hands-on experience and learning via direct interaction with senior colleagues. To overcome these challenges, we organized a hybrid workshop where simulation-based learning modules, and direct and virtual interaction with surgeons during live surgeries or didactic lectures were utilized to help delegates in understanding the nuances of neurosurgery.MethodsA 3-day hybrid workshop was held in March 2021, which was attended by 133 delegates. A structured questionnaire was utilized to record their feedback.ResultsAn overwhelming majority of the respondents (94.1%, n = 64) found hybrid conferences to be better than an online conference. Most of the respondents (88.3%, n = 60) rated the utility of direct face-to-face interaction to be more satisfying as compared with online interaction with faculty during a webinar. Again, many the respondents (86.8%, n = 59) believed that similar hybrid events will be the new normal given the current situation of COVID-19 pandemic. A large majority (88.2%, n = 60) of the respondents reported that they will prefer a hybrid event over an online conference.ConclusionsIn this era of the COVID-19 pandemic, "hybrid" microneurosurgery workshops offer unique opportunities to enhance surgical skills acquisition by hands-on simulation-based learning and observing live surgical demonstrations, apart from 2-way interactions with experts under one roof. This may be a stepping stone for what lies ahead in the future of neurosurgical training.
