Description

The accurate prediction technique of cat gestational age
Technical field
Research the present invention relates to veterinary clinic to foetal animal, more particularly, to a kind of accurate prediction side of cat gestational age Method.
Background technique
Animal doctor to gestation and divides the accurate evaluation of animal (such as cat, dog) gestational age in clinical or scientific research process The optimum management of childbirth is most important, can greatly improve the survival rate of the fetuses such as cat, dog, especially if not knowing mating day The prediction of phase, gestational age and childbirth phase are just particularly important.Pet clinic in can be used ultrasound to entire During Pregnancy into Row monitoring, has the parameter that can predict gestational age, such as biparietal diameter (BD), abdomen diameter (AD) stomach function regulating diameter etc. in canine.And In veterinary clinic, ovulation period and prediction delivery time can also be determined by measuring LH peak value and the progesterone of dog.
Currently, for speculating that the method for cat gestational age is very old on veterinary clinic, to cat cyesiognosis and assessment of gestational age skill The research majority of art there is no complete, fine cyesiognosis ultrasound map based on conventional two-dimensional ultrasound, therefore the measurement of cat gestational age It only resides within using machine preset parameter level, there are biggish errors in the estimation of final gestational age.
Specifically, five major class are broadly divided into the method for dog cat gestational age prediction at present: (1) ovulation and hormone determination；(2) The time and developmental state of ultrasonic monitoring Fetal Embryonic or organ structure appearance predict gestational age and childbirth；(3) it is tied outside fetus The ultrasonic measurement of structure or fetal structural；(4) pass through the childbirth of the variation prediction of measurement fetus blood flow parameter and heart rate；(5) it is penetrated using X Line technology assesses gestational age；For these methods for canine, the variation by monitoring LH peak value and progesterone can both determine ovulation Time, due to the animal that cat is seasonal oestrus induced ovulation, only mating could induce ovulation, and lure it is also predicted that childbirth Number of copulations needed for leading LH peak value is unknown, and follicular cell is without leuteinization before preovulatory, therefore Concentration of Progesterone is only being arranged It can just increase after ovum, also only can just decline after childbirth, so the measurement of the Concentration of Progesterone of cat can neither be used in during oestrus Monitoring ovulation, can not be when close to childbirth to determine delivery time.Although and using X-ray can be in the pregnant middle and later periods to tire Number accurate evaluation, but fetal vitality can not be assessed.
When traditional cat gestational age prediction technique predicts Bangladesh's leopard cat gestational age, since certain indexs (are ovulated and are swashed Element measurement) measurement often due to artificial origin there are biggish error, accuracy can not meet research needs, therefore using surpass Audio clinic instrument explore it is a kind of can Accurate Prediction cat gestational age, in the method for effectively assessing cat fetal vitality clinical and scientific research is come Saying all seems extremely important.
Summary of the invention
The purpose of the present invention is to provide a kind of accurate prediction technique of cat gestational age, this method is simply easily grasped, and is predicted Accuracy is higher.
To achieve the above object, the present invention can take following technical proposals:
The accurate prediction technique of cat gestational age of the present invention are as follows:
So that pregnant cat is in dorsal position first, using diasonograph for animals scanning near pregnant cat uterus fetus head, finds Ulna and radius, and the length X of ulna is measured respectively1With the length X of radius2, then press ulna regression equation Y1=18.323X1+ 26.559 with radius regression equation Y2=19.485X2+ 26.738, calculate the gestational age Y, Y=Y of the cat fetus1=Y2。
After cat fetus gestational age d > 34 days, when cat uterus pregnant using diasonograph scanning for animals, first have to find pregnant cat Cornua uteri, and two are found near fetus head by caudal to head time successively each fetus of scanning along two sides cornua uteri A strong echo light band, i.e. ulna and radius；Wherein ulna is located on the inside of radius and ulna has olecranon, and measurement point is ulna and radius The line at two epiphysis midpoints.
When actual prediction, because kind is poor, figure etc. difference causes according to ulna regression equation and radius regression equation When calculated gestational age is inconsistent, Comprehensive Assessments are carried out in combination with other prediction gestational age technologies.
The present invention has the advantages that the ulna and radius due to cat are located at cat forelimb, can be presented with the growth of gestational age flat Steady linear increase, and have extremely strong linear relationship with pregnant age, so ulna and the index of correlation of radius length variation can be used as The new method of gestational age identification is applied in practice, and ulna is located on the inside of radius and ulna has olecranon, and identification is high, it is easier to Precise measurement.
The present invention is directed to by monitoring Bangladesh leopard cat fetus ulna, radius developmental state, and then explore a kind of new Gestational age prediction technique can provide foundation for the leopard cat cyesiognosis of clinical Bangladesh.
Detailed description of the invention
Fig. 1 is cat forelimb bone schematic diagram.
Fig. 2 is cat fetus B ultrasound figure.
Specific embodiment
More detailed explanation is done to the present invention below by specific embodiment, to facilitate the reason of those skilled in the art Solution.
Shown in FIG. 1 is cat forelimb bone schematic diagram, it can be seen from the figure that ulna is located on the inside of radius and ulna has hawk Mouth.
Test object of the present invention is the pregnant cat that estimated cat gestational age is more than 34 days.
The accurate prediction technique of cat gestational age of the present invention are as follows:
So that pregnant cat is in dorsal position (and carrying out safe and reliable fixation) first, uses SIUI diasonograph Apogee for animals 1200V(linear array probe L8L38C) cornua uteri that finds pregnant cat, respectively along two sides cornua uteri by caudal to head time successively scanning Each fetus.
A selected wherein fetus (to ensure accuracy, it is desirable that every fetus will measure), B ultrasound figure is as shown in Fig. 2, visit Head finds the head of fetus along the sagittal plane of fetus first, and two parallel strong echo light bands are found near fetus head and are Ulna and radius, ulna is located on the inside of radius and there is olecranon on ulna top, is then accurately surveyed to the length of ulna and radius Amount.
After measuring the accurate size of ulna and radius, can press ulna regression equation and radius regression equation respectively into Row calculates:
Y1=18.323X1+26.559
Y2=19.485X2+26.738
Y1=Y2, accordingly, how many days the cat gestational age Y that can be predicted the pregnant cat is.
The change in size of ulna and radius that the following table 1 is measured according to being and then the cat gestational age predicted variation.
The variation of 1 ulna and radius length of table
Table 3-2-5-1 Changes in length of ulna and radius
Whens Y1 and Y2 numerical value does not wait after actual measurement calculating, it can be combined with other gestational age prediction modes, thus more acurrate Prediction gestational age.It in clinical practice, can be with the Developmental maturity knot of Foetal organ when assessing gestational age using the method for the present invention It is assessed altogether, to improve the accuracy of prediction.
