A Comparison of Five Adhesive Tapes for Securing Endotracheal Tube in a Manikin

Background: Adhesive tape is the common method for endotracheal tube (ETT) secured to prevent tube displacement and unplanned extubation in an anesthesia setting. However, it is unclear which tape is superior for ETT fixation among the various tapes used in clinical practice. This study examines the force required to move 2 cm ETT and extubate ETT from an intubation manikin with five different adhesive tapes. Methods: We orally intubated an adult intubation manikin with an inner-diameter 7.5 mm ETT, inflated the cuff to 20 cm H2O. Then we secured ETT with five different adhesive tapes (Transpore tapeTM, Urgosyval tape®, TransporeTM White tape, Multipore tape, DuraporeTM tape) in a conventional fixation method. A digital force gauge was connected to the ETT and pulled in a direction erected to the oral cavity. We measured the force required to move 2 cm ETT and extubate ETT (defined as 5 cm ETT displacement) from the manikin. Data were analyzed with one-way analysis of variance, with P < 0.05. Results: DuraporeTM tape had the largest average force of 2 cm displacement (58.9 ± 5.7N) (P < 0.05). The extubation force of DuraporeTM tape (59.7 ± 4.9N) was larger than Urgosyval® tape (40.4 ± 2.9N) (P < 0.05), TransporeTM tape (48.7 ± 5.1N) (P < 0.05), Transpore WhiteTM tape (48.7 ± 5.1N) (P < 0.05). Conclusion: DuraporeTM tape was superior to the other four tapes (TransporeTM tape, Urgosyval® tape, TransporeTM white tape, Multipore tape) in holding the ETT in place in the manikin.

Pre-placement of adhesive tape around wound sites can prevent air leakage in negative pressure wound therapy procedures

The introduction of negative pressure wound therapy has revolutionized the management of complicated wounds.However,the maintenance of an effective negative pressure environment is difficult in some instances,such as wounds in close proximity to an intestinal stoma or wounds surrounded by external fixations.We found that adhesive tape adheres more easily to itself than to wet skin or uneven surfaces.Therefore,we placed adhesive tape around surgical wounds prior to covering them with foam and sealing them with more tape.As a result of the strong adhesive force between pieces of tape,this method could provide a better environmental seal,even in situations where space is limited.Pre-placed adhesive tape around the wound site prior to foam placement could provide sufficient adhesion to maintain a continuous negative pressure environment during treatment.

Development and first evaluation of an attractant impregnated adhesive tape against blood-sucking flies

Stable flies are one of the most important arthropod pests of livestock that reduce cattle weight gain and milk production leading to annual economic losses in excess of$2 billion to the US cattle industry.The host-seeking behavior is primarily mediated by associated odors from stable fly larval development environments and host animals.The present paper reports the development and evaluation of attractant-impregnated adhesive tapes to reduce stable fly attacks on cattle.Laboratory bioassays showed that only m-cresol impregnated adhesive tapes caught significantly more stable flies(16±1)than the control tape without attractant added(7±1),with a 77%fly recapture rate.Attractant-impregnated adhesive tapes deployed in cattle feedlots showed significant impacts in reducing fly population,with a total of one million stable flies captured over a period of three weeks(mean catches from 57596 to 102088 stable flies per trap per week).It further relieved cattle stress with a significant reduction of biting fly avoidance behavior,(6±0.4 cows observed with tail wagging in control vs.3±0.4 from the trap-deployed).The efficacy of the developed tapes lasted up to 1-week longevity,although 70%of m-cresol was released starting from the second day.The m-cresol impregnated adhesive tape provided an 80%reduction in cattle stress due to stable fly attack.This is the first report of a technology developed by integrating an attractant compound into an adhesive material on a plastic film with demonstrated effectiveness in trapping biting flies that attack livestock animals.

Gecko-Like Dry Adhesive Surfaces and Their Applications: A Review

Gecko has the ability to climb flexibly on various natural surfaces because of its fine layered adhesion system of foot,which has motivated researchers to carry out a lot of researches on it.Significant progresses have been made in the gecko-like dry adhesive surfaces in the past 2 decades,such as the mechanical measurement of adhesive characteristics,the theoretical modeling of adhesive mechanism and the production of synthetic dry adhesive surfaces.Relevant application researches have been carried out as well.This paper focuses on the investigations made in recent years on the gecko-like dry adhesive surfaces,so as to lay the foundation for further research breakthroughs.First,the adhesion system of gecko’s foot and its excellent adhesive characteristics are reviewed,and the adhesive models describing the gecko adhesion are summarily reviewed according to the diff erent contact modes.Then,some gecko-like dry adhesive surfaces with outstanding adhesive characteristics are presented.Next,some application researches based on the gecko-like dry adhesive surfaces are introduced.Finally,the full text is summarized and the problems to be solved on the gecko-like dry adhesive surfaces are prospected.
