Ketamin/ksilazin anestezi hemoreolojik bakış açısından güvenlidir: bir ilk rapor 'yazarın yanıtı'

Akbudak ve ark.’nın “Ketamin/ksilazin anestezi hemoreolojik bakış açısından güvenlidir: bir ilk rapor” başlıklı araştırma makalesi ile ilgili bir “Editöre Mektup” yazılarak çalışmayla ilgili bazı eleştirilerde bulunulmuş ve çalışmanın özgün olmadığı iddia edilmiştir. Bu yazı, iddialara cevap verilmesi ve çalışmanın “ÖZGÜN” olduğunun bilimsel kurallara uyularak, gerekli literatür bilgileri sunularak net biçimde ortaya konması amacıyla kaleme alınmıştır.

Purpose: Some anesthetic drugs are known to have influence on circulation due to hemorheological effects.We aimed to investigate the possible effects of ketamin-xylazine anesthesia, which is extensively used inexperimental animal laboratories on hemorheological parameters.Materials and methods: Adult, male Wistar-Albino rats were divided into two as control (pre-anesthesia)and post-anesthesia (n=17). Ketamin-HCl/Xylazine-HCl (90 mg/kg-10 mg/kg) were injected intraperitoneally.Intracardiac heparinized blood was collected either without anesthesia (control group) or after anesthesia(post-anesthesia group) following the loss of reflexes such as righting, cornea and withdrawal. Erythrocytedeformability was determined by an ektacytometer, while WBV (at shear rates of 38, 76 and 190 s-1) and PV(at 190 s-1 shear rate) at standard (40%) and otolog hematocrit (Hct) were measured via a cone-plate rotationalviscometer.Results: Mean time taken for the disappearance of righting reflex was 4±3.6, corneal reflex 8±6.8 and forwithdrawal reflex 10±6.7 min. 90 mg/kg Ketamin-10 mg/kg Xylazine administration did not affect RBCdeformability, WBV and PV of the rats.Conclusion: These results demonstrate that, use of Ketamin/Xylazine anesthesia may be recommendedespecially when dealing with hemorheological, cardiovascular and hematological parameters.
