Samuel Beckett's Waiting for Godot and the Absurd Theatre

The research consists of three sections and conclusion. Section one deals with the idea of absurdity in the modern world has attracted many writers to thereby portray the bitter reality of a society being dominated by the discourse of modernism Section two focuses on Samuel Beckett's life and his works. In addition, Beckett places his characters in a dreamlike setting in his two-act tragicomedy Waiting for Godot (1948). The play has been criticized by a number of people; in 1953, Jacques Audiberin called it "a perfect work which deserves a triumph". Studies in Section Three Anticipating Godot as an Absurd Drama: The paper concludes with a list of references and a conclusion.. This study examines the meaning-seeking process, existentialist themes, and the human condition in Samuel Beckett's Waiting for Godot within the context of absurd theater. The play's repetitive dialogue and austere setting make it an ideal illustration of the absurdist belief that life is meaningless. The research looks at how the characters, Vladimir and Estragon, interact to show how their waiting for the illusive Godot symbolizes the pointlessness of life and the fight against hopelessness. The ridiculous routines and mutual dependence of the characters highlight the alienation and loneliness that come with living in the contemporary world. By situating Waiting for Godot in the context of Absurd Theatre, this research emphasizes Beckett's innovative use of language and structure, which challenges traditional narrative forms and invites audiences to confront the complexities of existence. Ultimately, the study reveals how Beckett's work serves as a poignant commentary on the human experience, encapsulating the essence of Absurdism through its exploration of time, identity, and hope.

Trauma care supported through a global telemedicine initiative during the 2023–24 military assault on the Gaza Strip, occupied Palestinian territory: a case series

Hospitals, patients, and health-care workers are legally protected by international humanitarian law and the Geneva Convention. However, since Oct 7, 2023, the health-care system in the Gaza Strip, occupied Palestinian territory, has been under unprecedented direct military attacks by Israel, with support for patients proving to be challenging for the remaining health-care workers. Peer-to-peer telemedicine holds promise for assisting surgeons in high-risk, low-resource environments, but might be of reduced utility in extremely austere settings. We present a patient case series of traumatic injuries shared in an international telemedicine group by the surgical team at Nasser Medical Complex, also known as Nasser Hospital, the largest remaining partially functioning hospital in Gaza. WhatsApp (Meta; Menlo Park, CA, USA), a widely available and user-friendly end-to-end encrypted smartphone application, was used to facilitate consultations for weapon-inflicted injuries. All the presented patient cases were shared after obtaining verbal consent from the patients and discussed through a multidisciplinary team approach. The group was developed into a community with more than 15 specialty and injury-oriented subgroups and over 1000 members who joined through non-targeted social media outreach followed by snowball recruitment. Prospective registration and formal ethics approval in Gaza was impossible because the Ministry of Health, including the local Helsinki Committee, had suspended all operations. In June, 2024, we obtained ethics approval from the local Helsinki committee in Gaza. We present 12 select patient case studies from a pool of hundreds of patients admitted to Nasser Hospital between Jan 28 and Feb 12, 2024. Four (33%) of the 12 patients were female and eight (67%) were male, with four patients (33%) being children (younger than 18 years). The age range was between 3 years and 70 years, with a median age of 25 years. Most patients presented with penetrating injuries (11 [92%] of 12), with six patients presenting with wounds secondary to fragment injury, and five patients presenting with wounds due to gunshots. One patient presented with a direct blast injury. The site of reported injuries included head and neck areas (four [33%] of 12), abdomen (four [33%] of 12), chest (three [25%] of 12), pelvis (two [17%] of 12), and limbs (one [8%] of 12). Most patients were lost to follow-up (11 [92%] of 12) and were affected by the invasion of the hospital by the Israeli Defense Forces, which subsequently rendered the hospital non-functional. One patient died following their injury. The health-care team at the now non-functioning Nasser Hospital in southern Gaza adapted their allocation and distribution of extremely low resources and relied on smartphones for specialised telemedicine outreach purposes. This enhanced the capability of the medical teams in management of mass casualties of military assaults that few are trained to work in. Nonetheless, the options available to a health-care system that is under-staffed, under-served, and under siege, are extremely constrained, regardless of such telemedicine initiatives. None.

Development and testing of a deep learning algorithm to detect lung consolidation among children with pneumonia using hand-held ultrasound.

Severe pneumonia is the leading cause of death among young children worldwide, disproportionately impacting children who lack access to advanced diagnostic imaging. Here our objectives were to develop and test the accuracy of an artificial intelligence algorithm for detecting features of pulmonary consolidation on point-of-care lung ultrasounds among hospitalized children. This was a prospective, multicenter center study conducted at academic Emergency Department and Pediatric inpatient or intensive care units between 2018-2020. Pediatric participants from 18 months to 17 years old with suspicion of lower respiratory tract infection were enrolled. Bedside lung ultrasounds were performed using a Philips handheld Lumify C5-2 transducer and standardized protocol to collect video loops from twelve lung zones, and lung features at both the video and frame levels annotated. Data from both affected and unaffected lung fields were split at the participant level into training, tuning, and holdout sets used to train, tune hyperparameters, and test an algorithm for detection of consolidation features. Data collected from adults with lower respiratory tract disease were added to enrich the training set. Algorithm performance at the video level to detect consolidation on lung ultrasound was determined using reference standard diagnosis of positive or negative pneumonia derived from clinical data. Data from 107 pediatric participants yielded 117 unique exams and contributed 604 positive and 589 negative videos for consolidation that were utilized for the algorithm development process. Overall accuracy for the model for identification and localization of consolidation was 88.5%, with sensitivity 88%, specificity 89%, positive predictive value 89%, and negative predictive value 87%. Our algorithm demonstrated high accuracy for identification of consolidation features on pediatric chest ultrasound in children with pneumonia. Automated diagnostic support on an ultraportable point-of-care device has important implications for global health, particularly in austere settings.

Designing the Prolonged Field Care Kit (PFAK) to Address the Logistical Challenges of Future Combat Casualty Care.

Prolonged Casualty Care (PCC) is a military adaptation aimed at providing pre-hospital care in austere settings when evacuation is delayed or even impossible. Current lack of standardized medical equipment and size/weight restrictions of military packs during dismounted operations hinder effective PCC. We sought to design a standardized, practical, and effective prolonged field care kit (PFAK) to enable widespread implementation of PCC. We reviewed Joint Trauma System Clinical Practice Guidelines to generate a list of potential contents of the PFAK. We obtained Institutional Review Board (IRB) exemption and then conducted stakeholder surveys of combat casualty care experts across the Joint Trauma System using a modified Delphi survey approach. We established a civil-military working group that provided in-depth qualitative feedback on the PFAK contents and provided an initial design of a long-range medical rucksack (LMR) to house it. Responses were analyzed using mean rank scores to help determine initial components of the PFAK. Tactical subject-matter experts tested and evaluated the PFAK and LMR prototype in austere conditions to refine the design. Review of the PCC Clinical Practice Guidelines generated 49 medications and 301 potential supplies as potential PFAK contents. The first Delphi survey was sent to 100 stakeholders (overall response rate of 60%). After the first survey, contents were narrowed to a list of the most essential 27 medications and 105 other components. Iterative prototypes of the PFAK and LMR were tested to determine ergonomics, portability, flexibility, and equipment compartmentalization to facilitate use in emergencies. The prototype was optimized to address the clinical, logistical, and tactical requirements of PCC across a variety of platforms and environmental conditions. Given the changing battlefield environment, efficient and effective PCC will play an increasingly important role in the management of combat trauma. The PFAK can meet this need by providing a practical and standardized resuscitation kit generated by expert military and trauma personnel consensus, carried conveniently in the LMR.

Non-therapeutic laparotomies in military trauma (2009-2014).

Combat casualties are frequently injured in austere settings where modern imaging modalities are unavailable. Exploratory laparotomies are often performed in these settings when there is suspicion for intra-abdominal injury. Prior studies of combat casualties reported non-therapeutic laparotomy (NTL) rates as high as 32%. Given improvements in combat casualty care over time, we evaluated NTLs performed during later years of the wars in Iraq and Afghanistan. Military personnel with combat-related injuries (6/1/2009-12/31/2014) who underwent exploratory laparotomy based on concern for abdominal injury (i.e. not performed for proximal vascular control or fecal diversion) and were evacuated to Landstuhl Regional Medical Center (Germany) before being transferred to participating U.S. military hospitals were assessed. An NTL was defined as a negative laparotomy without substantial intra-abdominal injuries requiring repair. Characteristics, indications for laparotomy, operative findings, and outcomes were examined. Among 244 patients who underwent laparotomies, 41 (16.8%) had NTLs and 203 (83.2%) had therapeutic laparotomies (i.e. positive findings). Patients with NTLs had more computed tomography scans concerning for injury (48.8% vs 27.1%; p = 0.006), less penetrating injury mechanisms (43.9% vs 71.9%; p < 0.001), and lower Injury Severity Scores (26 vs 33; p = 0.003) compared to patients with therapeutic laparotomies. Patients with NTLs were also less likely to be admitted to the intensive care unit (70.7 vs 89.2% for patients with therapeutic laparotomies; p = 0.007). No patients with NTLs developed abdominal surgical site infections (SSI) compared to 16.7% of patients with therapeutic laparotomies (p = 0.002). There was no significant difference in mortality between the groups (p = 0.198). Our proportion of NTLs was lower than reported from earlier years during the wars in Iraq and Afghanistan. No infectious complications from NTLs (i.e. abdominal SSIs) were identified. Nevertheless, surgeons should continue to have a low threshold for exploratory laparotomy in military patients in austere settings with concern for intra-abdominal injury.

Hypnosis in Burn Care: Efficacy, Applications, and Implications for Austere Settings

Burn injuries are among the most traumatic events a person can endure, often causing significant psychological dysfunction and severe pain. Hypnosis shows promise as a complementary intervention to manage pain and reduce the psychological distress associated with burn injury and treatment. This paper reviews the literature regarding hypnosis and potential applications of hypnosis in the management of burns. Hypnosis offers an effective, low-cost intervention that is widely applicable in the management of burns and can play a role in more acute and austere settings where resources are often limited.

Incomes to Outcomes: A Global Assessment of Disparities in Cleft and Craniofacial Treatment.

Recent investigations focused on health equity have enumerated widespread disparities in cleft and craniofacial care. This review introduces a structured framework to aggregate findings and direct future research. Systematic review was performed to identify studies assessing health disparities based on race/ethnicity, payor type, income, geography, and education in cleft and craniofacial surgery in high-income countries (HICs) and low/middle-income countries (LMICs). Case reports and systematic reviews were excluded. Meta-analysis was conducted using fixed-effect models for disparities described in three or more studies. N/A. Patients with cleft lip/palate, craniosynostosis, craniofacial syndromes, and craniofacial trauma. N/A. One hundred forty-seven articles were included (80% cleft, 20% craniofacial; 48% HIC-based). Studies in HICs predominantly described disparities (77%,) and in LMICs focused on reducing disparities (42%). Level II-IV evidence replicated delays in cleft repair, alveolar bone grafting, and cranial vault remodeling for non-White and publicly insured patients in HICs (Grades A-B). Grade B-D evidence from LMICs suggested efficacy of community-based speech therapy and remote patient navigation programs. Meta-analysis demonstrated that Black patients underwent craniosynostosis surgery 2.8 months later than White patients (P < .001) and were less likely to undergo minimally-invasive surgery (OR 0.36, P = .002). Delays in cleft and craniofacial surgical treatment are consistently identified with high-level evidence among non-White and publicly-insured families in HICs. Multiple tactics to facilitate patient access and adapt multi-disciplinary case in austere settings are reported from LMICs. Future efforts including those sharing tactics among HICs and LMICs hold promise to help mitigate barriers to care.

Irregular warfare must combine good medicine, with both good tactics and good strategies: Position paper by the French Special Operations Forces Medical Command.

Military operations are no longer limited to the application of counterterrorism and counterinsurgency strategies; they are now characterized by hybrid, irregular, and unconventional features. While some authors have indicated the need for medical support to adapt to these new modes of military operations, they have focused mainly on the tactical level of care on the battlefield. As Sun Tzu states, "Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat," further proposals are still needed on the application of both medical tactics and medical strategies in irregular warfare. Medical experts from the French Special Operations Forces (SOF) Medical Command have identified specific medical challenges that special operations face in the context of the current transformation of armed confrontations into irregular warfare. This position paper presents original tactical medical proposals for improving medical support in irregular warfare, ranging from the definition of a Primary-Alternate-Contingency-Emergency medical plan to the promotion of telemedical support. Original strategic medical proposals have highlighted the importance of recognizing medical issues in irregular warfare, including the medical actions carried out through and with local partners and the multiple approaches to countering medical threats. The SOF medical community must be closely involved with and facilitate the responses to the shift to irregular warfare. International collaboration and interoperability are more necessary than ever, as they will enable a more effective combination of good medicine with both good tactics and good strategies. These perspectives can also be extended to improve medical care in the conventional armed forces and austere civilian settings. Therapeutic/Care Management; Level V.

Managing pediatric-onset multiple sclerosis in an austere setting: A case report.

Pediatric-onset multiple sclerosis (POMS) is the most common demyelinating disease in children. Patients suffer from physical disability, cognitive impairment, and psychosocial challenges. Management requires a multidisciplinary care team. Here we present a case of an 11-year-old boy with POMS who relocated to Guam prior to initiation of a disease-modifying treatment and who experienced a flare without immediate access to an MRI or a child neurologist. Care required the combined efforts of ophthalmology, pediatrics, and emergency medicine in Guam, real-time remote guidance by child neurology, and asynchronous collaboration with cardiology and child neurology. As a result, the immediate flare was accurately diagnosed and treated with steroids, the patient was started on Fingolimod, and an emergency management plan for future flares was constructed. This case illustrates the nuances of both the acute and chronic management of multiple sclerosis in a resource-limited setting and how a combination of synchronous and asynchronous telemedicine was able to achieve a satisfactory treatment plan.

Burn Wound Care Strategies for the Battlefield and Austere Settings

Burns are commonly encountered in the battlefield environment; however, the availability of burn expertise and specialized supplies is variable. Initial burn care should remain focused on cooling the burn, preventing hypothermia, basic wound cleansing, and evacuation. Key ongoing burn wound management principles include wound debridement, accurate burn size and depth estimation, wound care, ongoing wound evaluation, and treatment of suspected Gram-negative wound infection. Operative management should be limited to urgent procedures, and definitive burn management should be performed only after evacuation to a higher level of care. Flexibility, creativity, and the ability to adapt care to the tactical environment are key to the successful management of burn injuries in battlefield and austere settings.

Leveraging Technology for Vestibular Assessment and Rehabilitation in the Operational Environment: A Scoping Review.

The vestibular system, essential for gaze and postural stability, can be damaged by threats on the battlefield. Technology can aid in vestibular assessment and rehabilitation; however, not all devices are conducive to the delivery of healthcare in an austere setting. This scoping review aimed to examine the literature for technologies that can be utilized for vestibular assessment and rehabilitation in operational environments. A comprehensive search of PubMed was performed. Articles were included if they related to central or peripheral vestibular disorders, addressed assessment or rehabilitation, leveraged technology, and were written in English. Articles were excluded if they discussed health conditions other than vestibular disorders, focused on devices or techniques not conducive to the operational environment, or were written in a language other than English. Our search strategy yielded 32 articles: 8 articles met our inclusion and exclusion criteria whereas the other 24 articles were rejected. There is untapped potential for leveraging technology for vestibular assessment and rehabilitation in the operational environment. Few studies were found in the peer-reviewed literature that described the application of technology to improve the identification of central and/or peripheral vestibular system impairments; triage of acutely injured patients; diagnosis; delivery and monitoring of rehabilitation; and determination of readiness for return to duty. This scoping review highlighted technology for vestibular assessment and rehabilitation feasible for use in an austere setting. Such technology may be leveraged for prevention; monitoring exposure to mechanisms of injury; vestibular-ocular motor evaluation; assessment, treatment, and monitoring of rehabilitation progress; and return-to-duty determination after vestibular injury. The future of vestibular assessment and rehabilitation may be shaped by austere manufacturing and 3D printing; artificial intelligence; drug delivery in combination with vestibular implantation; organ-on-chip and organoids; cell and gene therapy; and bioprinting.

Enteral Resuscitation: A Field-Expedient Treatment Strategy for Burn Shock during Wartime and in Other Austere Settings

Burn injuries are a constant threat in war. Aspects of the modern battlefield increase the risk of burn injuries and pose challenges for early treatment. The initial resuscitation of a severely burn-injured patient often exceeds the resources available in front-line medical facilities. This stems mostly from the weight and volume of the intravenous fluids required. One promising solution to this problem is enteral resuscitation with an oral rehydration solution. In addition to being logistically easier to manage, enteral resuscitation may be able to mitigate secondary injuries to the gut related to burn shock and systemic immunoinflammatory activation. This has been previously studied in burn patients, primarily using electrolyte solutions, with promising results. Modern ORS containing sodium, potassium, and glucose in ratios that maximize gut absorption may provide additional benefits as a resuscitation strategy, both in terms of plasma volume expansion and protection of the barrier and immune functions of the gut mucosa. While enteral resuscitation is promising and should be used when other options are not available, further research is needed to refine an optimal implementation strategy.

Moving toward point-of-care surgery in Ukraine: testing an ultra-portable operating room in an active war zone.

In conflict zones, providers may have to decide between delaying time-sensitive surgeries or performing operative interventions in the field, potentially subjecting patients to significant infection risks. We conducted a single-arm crossover study to assess the feasibility of using an ultraportable operating room (U-OR) for surgical procedures on a porcine cadaver abdominal traumatic injury model in an active war zone. We enrolled participants from an ASSET-type course designed to train Ukrainian surgeons before deployment to active conflict zones. They performed three standardized consecutive abdominal surgical procedures (liver, kidney, and small bowel injury repair) with and without the U-OR. Primary outcomes included surgical procedurecompletion rate, procedure time, and airborne particle count at the start of surgery. Secondary survey-based outcomes assessed surgery task load index (SURG-TLX) and perceived operative factors. Fourteen surgeons performed 76 surgical procedures (38 with the U-OR, 38 without the U-OR). The completion rate for each surgical procedure was 100% in both groups. While the procedure time for the liver injury repair did not differ significantly between the two groups, the use of the U-OR was associated with a longer time for kidney (155 vs. 56s, p = 0.002), and small bowel (220 vs. 103s, p = 0.004) injury repair. The average airborne particle count within the U-OR was substantially lower compared to outside the U-OR (6,753,852 vs. 232,282 n/m3, p < 0.001). There was no statistically significant difference in SURG-TLX for procedures performed with and without the U-OR. The use of the U-OR did not affect the procedure completion rate or SURG-TLX. However, there was a marked difference in airborne particle counts between inside and outside the U-OR during surgery. These preliminary findings indicate the potential feasibility of using a U-OR to perform abdominal damage-control surgical procedures in austere settings.

Water Decontamination Products for Wound Irrigation in Austere Environments: Benchtop Evaluation and Recommendations.

Irrigation is used to minimize infection of open wounds. Sterile saline is preferred, but potable water is becoming more widely accepted. However, the large volumes of water that are recommended are usually not available in austere environments. This study determined the long-term antimicrobial effectiveness of military purification powder compared with currently available civilian methods. The study also compared the physical characteristics and outcomes under the logistical constraints. Six commercially available water decontamination procedures were used to decontaminate five different sources of water (pond water, river water, inoculated saline, tap water, and sterile saline). Each product was evaluated based on six different parameters: bacterial culture, pH, turbidity, cost, flow rate, and size. All methods of treatment decreased the bacterial count below the limit of detection. However, they had variable effects on pH and turbidity of the five water sources. Prices ranged from $7.95 to $350, yielding 10-10,000L of water, and weighing between 18 and 500g. In austere settings, where all equipment is carried manually, no single decontamination device is available to optimize all the measured parameters. Since all products effectively reduced microbial levels, their size, cost, and production capability should be evaluated for the intended application.

Expeditionary Surgeons: Essential to Surgical Leadership in World War II and Today.

This presidential address, given during the Annual Symposium of the Excelsior Surgical Society of the American College of Surgeons, explores the origins of the expeditionary surgeon. The essential traits of such a surgeon-leader are defined using examples from history and are then used to examine the leadership of Edward D Churchill during World War II as the prototypical expeditionary surgeon. In the future, identifying key military surgical leaders as expeditionary surgeons would serve our nation's interests well in preserving our fighting force on the battlefield. Consideration should be given to formally training and designating such surgical leaders for the military and other austere settings.

Pharmacologic Considerations for Antimicrobials and Anticoagulants after Burn Injury

Derangements in pharmacokinetics and pharmacodynamics (PK/PD) of burn patients are poorly understood and lacking consistent data. This leads to an absence of consensus regarding pharmacologic management of burn patients, complicating their care. In order to effectively manage burn critical illness, knowledge of pharmacologic parameters and their changes is necessary. It is also imperative that the clinician understands how these changes will affect drug dosing. A common practice is to increase antibiotic dosing and/or frequency; however, this may not be necessary and doses should be adjusted to patient- and drug-specific parameters. Additionally, monitoring assays for antibiotic levels as well as coagulation factors can be useful for adjusting dosages to best treat the patient. This review focuses on alterations in PK/PD as well as other physiologic changes after burn injury, with special reference to care in military and austere settings.

Psychological First Aid for Wilderness Trauma: Interventions for Expedition or Search and Rescue Team Members.

When exposed to actual or threatened death or serious injury in austere settings, expedition members are at risk of acute stress reactions, as are search and rescue members involved with extricating the patient. Acute stress reactions are a normal response to significant trauma and commonly resolve on their own. If they do not, they can lead to post-traumatic stress disorder (PTSD), a set of persistent symptoms that cause significant effects on the person's life. Medication has a limited preventive role in the field for treatment of stress partly because so few are trained to administer it. Contrastingly, psychological first aid can be performed by lay team members with minimal training. Psychological first aid consists of interventions attempting to encourage feelings of safety, calm, self-efficacy, connection, and hope. These are interventions that provide guidance to not make the situation emotionally worse and might have a preventive effect on later development of PTSD. They are valuable in the field not only for the patient but also for affected team members as well as for search and rescue team members who may be indirectly affected by the trauma and experience repercussions later.

Austere Diagnosis and Reduction of Anterior Shoulder Dislocations: 10-Year Review of a Ski Patrol-Based Program with Emergency Medical Technicians

Glenohumeral dislocations present a challenging management dilemma in austere settings where patient transport time may be prolonged. Expeditious reduction is preferable, but treatment is commonly expected to take place within a hospital or comparable facility. Through a novel shoulder injury program, professional ski patrollers trained as emergency medical technicians (EMTs) have diagnosed and reduced anterior shoulder dislocations using biomechanical techniques without sedation or analgesia for over 20 y. Summary records have been maintained to track the performance and safety of this program. Five hundred forty-six records of winter sports-related shoulder injuries from 2009-10 to 2019-20 were retrospectively analyzed to determine the assessment performance and dislocation reduction efficacy of EMTs, with the intent of ascertaining whether EMT-trained practitioners can reliably and safely diagnose and reduce anterior shoulder dislocations without premedication in a remote and resource-limited setting. EMTs identified anterior shoulder dislocations with 98% sensitivity and 96% diagnostic accuracy. The overall success rate of reduction attempts was 86%, or 88% when limited to confirmed anterior dislocations. Two fracture-dislocations and 4 misdiagnoses were manipulated. No instances of iatrogenic harm were identified, and no patients who underwent successful reductions required ambulance transportation. With appropriate education and within a structured program, EMT-trained practitioners can reliably and safely diagnose and reduce anterior shoulder dislocations using biomechanical techniques without premedication in remote and resource-limited environments. Implementation of similar programs in austere settings has the potential to improve patient care. Further, using biomechanical reduction techniques may reduce reliance on procedural sedation irrespective of care setting.

Comparison of Commonly Carried Liquids Against Commercial Ultrasound Gel for Use in the Backcountry Setting.

Point-of-care ultrasound (POCUS) is utilized in austere environments because it is lightweight, durable, battery powered, and portable. In austere settings, weight and space constraints are limitations to carrying dedicated ultrasound gel. Few studies have assessed commonly carried liquids as gel alternatives. The study objective was to assess the suitability of common food and personal care products as ultrasound coupling agents compared with that of commercial gel. A noninferiority study compared 9 products to commercial gel. Each substance was independently tested on 2 subjects by 2 sonographers covering 8 standardized ultrasound windows. Clips were recorded, blinded, and independently graded by 2 ultrasound fellowship-trained physicians on the ability to make clinical decisions and technical details, including contrast, resolution, and artifact. A 20% noninferiority margin was set, which correlates to levels considered to be of reliably sufficient quality by American College of Emergency Physicians' guidelines. The substances included water, soap, shampoo, olive oil, energy gel, maple syrup, hand sanitizer, sunscreen, and lotion. A total of 300 of 318 (94%) clips met the primary endpoint of adequacy to make a clinical decision. All media, except sunscreen, were noninferior to commercial gel in the ability to make a clinical decision (α=0.05). In terms of secondary outcomes, resolution, artifact, and contrast, all substances were noninferior to commercial gel (α=0.05). The sonographers concluded that all gel alternatives' usability performed similarly to commercial gel, with the exception of energy gel. Of the 9 substances tested, 8 were noninferior to commercial gels for clinical decisions. Our study indicates that several POCUS gel substitutes are serviceable to produce clinically adequate images.
