HD results

The other question is who did the examination, was it always the same person, did it differ what was his qualification etc.

Hello Ina

I will try to anser as best as I can

This is some more info translated by google

"F.C.I. since 2007 has regulated that all dogs undergoing
X-ray monitoring of HD status is sedated (Hansson, 2007). In Sweden has been a requirement since earlier that the dogs be "medicated before investigation so that they are sufficiently relaxed at X-ray time "(SKK,
2004)."

"Author. Hjorth, Tove -08 Sederingsrutinens impact on the outcome of hip x-ray. Dept. of Clinical Sciences, SLU. Thesis (Swedish University of Agricultural Sciences, Faculty of Veterinary Medicine and Animal Science, Veterinary Program) "

Purpose
The purpose of this study was to obtain an indication of whether the choice of sedation affect the results of X-ray examination, and if the results will vary even between repeated exposures during the same sedation.

Materials and methods
Six, according to the owners clinically healthy dogs of the breed Golden Retrievers, between one and three years old (654-1430 days) were used in the study. The dogs were privately owned and gathered through contacts with breeders in Uppsala and Stockholm area.
All the dogs had detected HD status. Three of the dogs had a grade C in one or both hips. Three of the dogs had grade A or B. Which sedation dogs x-ray in at the registration completed the study were no
into account and these images are neither included in the study. Four of the dogs were males and two were females of which one was castrated. Two of the dogs with approved hip joints were half-siblings but the other was not closely related.
The dogs x-rayed twice at Image Diagnostic Clinic at University animal hospital in Uppsala (Sweden). At all times the dogs were positioned on a table of the same X-ray technicians, and the same person held the hind legs. Mechanical fixation of the hind legs were not used. If necessary for the dog would lie still was the dog's owner in the head end. For the first time x-rayed the dogs first wake up and three shots approved for readings were taken. After each image was moved dog around the table of who held the hind legs and then the next image back position by X-ray technician. After three images taken from awake dog manners were dog withmedetomidine and butorphanol (Domitor ® and Torbugesic ®) at a dose of 12 0.1 ml per 10 kg of each preparation, administered intramuscularly. When sufficient power sedation achieved was a further three images as described earlier. Dogs raised then with atipamezole (Anti Since ®) 0.1 ml per 10 kg. Six to fourteen days later traditions were dogs with acepromazine (Plegicil ®) 0.2 ml per 10 kg intramuscularly and when adequate sedation level achieved was three shots. The dogs were positioned again on the images. The three exposures taken during the same sedation will henceforth be called "X-opportunity".
The identity of the images, a total of 54 pieces, were removed before the reading and grading under F.C.I. The reading was at one time and the pictures in random order, one of SKK's official readers of high-definition X-ray. Each hip joint was assessed separately, and any comments on image quality was noted.
The results of X-ray surveys were translated into a numerical scale from 1 to 5, where A = 1 and E = 5, before a "mixed model" analysis of ordinal data (SAS procedure Glimmix) was conducted. We looked first at the choice of sedation in general had effect on earnings and the various sedation effect in relation to each other.
It also examined the effect of sedation differs between right and left
hip. The threshold for statistical significance was set at p = 0.05.

Results
Evidence from X-ray moment The number of pictures that were taken in order to get three assessment photos only varied at each X-ray time between three and nine. When the dogs were awake were on average 6.8
images / dog and this was X-ray technician in the two cases remain in the examination room to the pictures could be taken. Under sedation with medetomidine and butorphanol took an average of 4.0 frames per dog and acepromazinsedering at 4.8 frames per dog. A dog was not possible to x-ray either awake or under acepromazinsedering when the not lay still long enough for a picture could be taken, although X-ray technician
remained at the table when the picture was taken. The dog did well to X-ray sedated with medetomidine and butorphanol. The dog was excluded from the study and a reserve dog was introduced. Of the study's conclusion, the dogs were seen two dogs relaxed when they were fully
wake up in the investigation. Other dogs were more or less stressful. The number X-ray exposures at the moment without sedation did not differ between the dogs that was relaxed on the table and stretching himself. There was no difference in picture quality the images captured in awake and sedated dogs. The time needed for X-ray examinations was at least twice as long on osederade dogs and one longer acepromazinsederade dogs compared with dogs sedated with medetomidine and butorphanol.
Sederingsrutinens impact on earnings The results of X-ray examination can be seen in Table 1. Sedation is really have an effect on survey results. Right and left hip is affected in the same degree of sedation routine. When the dogs are sedated with a combination of medetomidine and butorphanol, they appear to be classified with a higher character than when they 13
sedated with acepromazine or osederade. The differences are significant (p = 0.04)."
