Does perioperative opioid infusion increase postoperative opioid requirement?

Autor: Sevim Karataş, Fevzi Yilmaz Gogus, Zeynep Eti, Kemal Tolga Saracoglu

Publikováno v: Ağrı - The Journal of The Turkish Society of Algology. 27:47-53

Objectives Opioids are the cornerstone therapy for the optimal pain management. Perioperative opioid infusion is accused of causing acute opioid tolerance, especially as the postoperative opioid requirement increases in time to provide efficient anal

Role of polydimethylsiloxane in properties of ternary materials based on polyimides containing zeolite Y

Autor: Sevim Karataş, Nilhan Kayaman-Apohan, Merve Biçen, Atilla Güngör

Publikováno v: Chemical Papers. 70

Mixed matrix materials, containing poly(dimethylsiloxane), phosphine oxide-based polyimide, and zeolite Y were prepared by means of blending hybridisation. The thermal stability of the materials and the hydrophobic properties were enhanced. The decre
