New and simple tools for easier obstetrics in cows – a tribute to
New and simple tools for easier obstetrics in cows – a tribute to female vets EBF Marseille 2013 Dr. Franz Schlederer vet.lichtegg@speed.at 4770 Andorf, Austria Dr. Schlederer`s obstetrics for cows and mares Dr. Schlederer`s eyehook for calves and foals Dr. Schlederer`s calf snare for calves and foals VET Lichtegg – Dr. Franz Schlederer EFB 2013 Torsio uteri VET Lichtegg – Dr. Franz Schlederer EFB 2013 Types of torsio uteri • Around 90% le>side torsio • Rightside torsio is rare. • Front-‐end und back-‐end calf posiDons . • RotaDon of the uterus mostly from 180°-‐270°, 90° • RotaDon is o>en not recognized by the farmers. VET Lichtegg – Dr. Franz Schlederer EFB 2013 Methods of uterus retorsion • Manually • With Instruments -‐ Caemmerer´s torsion fork/detorsion bar -‐ Kalchschmidt‘s calving hook -‐ GYN-‐sDck (new methode!) • Indirectly -‐ barmethod (video) • SecDo with retorsion VET Lichtegg – Dr. Franz Schlederer EFB 2013 Manual retorsion, standing cow VET Lichtegg – Dr. Franz Schlederer EFB 2013 Bar Method VET Lichtegg – Dr. Franz Schlederer Video EFB 2013 GYNsEck® by Dr. Schlederer THE „BIRTH“ of the IDEA: ….twisted uterus „in back-‐end posiDon“….. „I wasn´t strong enough to do a manual retorsion……no help to do the „bar-‐method“….. I had to improvise“ VET Lichtegg – Dr. Franz Schlederer EFB 2013 The real clue: A CombinaEon tool • GYN-‐sDck unites exisDng systems like torsio fork -‐ Caemmerer and Kühn´s obstetrical crutch in one tool. • BUT it is much more than this: • elasEc material aspect – came up as an accidental result of my cooperaDon with the school of technology in my home town which is specialised in plasDc materials. VET Lichtegg – Dr. Franz Schlederer EFB 2013 GYN-‐sEck® by Dr. Schlederer VET Lichtegg – Dr. Franz Schlederer EFB 2013 GYN-‐sEck® lenght of stick allows comfortable working and monitoring – 1 m VET Lichtegg – Dr. Franz Schlederer EFB 2013 OperaEonal procedure GYN-‐sEck ® VET Lichtegg – Dr. Franz Schlederer EFB 2013 Advantages of GYN-‐sEck® • Shorter duraEon of obstetric intervenDons • Gentle handling: the cow is likely to keep standing (only liIle abdominal press) • Easy Controlling of retorsion • Tissue -‐ safer than exisDng tools (plasDc, design, legs are fixed) • ReposiDon of a torsio uteri in a lying cow is possible with the GynsDck VET Lichtegg – Dr. Franz Schlederer EFB 2013 Further advantages • Fixed birth ropes on the legs (compared to tradiKonal systems where the cuLs oLen glide from the fork and can damage Kssues) • A>er the rotaDon the fixed ropes can be used immediately for pulling out the calf. No need for changing ropes (less exhausKng for vet and animal). VET Lichtegg – Dr. Franz Schlederer EFB 2013 The cow is lying dead calf, torsio fricEon movement VET Lichtegg – Dr. Franz Schlederer EFB 2013 Old system – Caemmerer´s Fork exhausEng handling…and many risks… VET Lichtegg – Dr. Franz Schlederer EFB 2013 „Torsional moment“ • When we start rotaDng the material takes up energy of the human force which is exposed immediately when the calf gets turning. (the sDck gives a „kick“) -‐> easier and effort-‐saving turning. • Physical force on the calf-‐extremiDes is reduced significantly. Another advantage is that the material of the ropes is elasDc (compared to chains). VET Lichtegg – Dr. Franz Schlederer EFB 2013 ReposiEon of PosiEonal Anomalies • Lower and anterior posiDon (in front-‐end or back-‐end) • Breech presentaDon: Kühn´s obstetrical crutch à bujocks pushed cranial and so the extremiDes can be changed to caudal more easily. • Pushing back the fetus by using the neck chest sling (so called „ski jumper posiDon“) • CorrecDon of the posiDon of the calf´s legs by using the new sling VET Lichtegg – Dr. Franz Schlederer EFB 2013 „Ski Jumper“ PosiEon VET Lichtegg – Dr. Franz Schlederer One rope system EFB 2013 Summary of applicaEons • Torsio uteri dexter et sinister • ReposiDon of posiDonal anomalies • PosiDoning the calf for secDo (bejer posiDoning for an easier surgery) • Hydrops aszites and „gas-‐calf“ (dead, emphysematous) VET Lichtegg – Dr. Franz Schlederer EFB 2013 Dr. Schlederer`s eyehook for calves and foals Smooth to the calf´s orbita, safer and easier to handle VET Lichtegg – Dr. Franz Schlederer EFB 2013 Obstetrics Prof. Benesch, Vienna 1947 „....In addition by pulling of the head the compression of the muscles and skin of the neck can be avoided.“ VET Lichtegg – Dr. Franz Schlederer EFB 2013 EYE-‐hook „the ergonomic design“ VET Lichtegg – Dr. Franz Schlederer EFB 2013 EYE-‐hook – elasEc fixaEon Two ways of applying the rope The ergonomic design of the hook leads to a good holding in the orbita VET Lichtegg – Dr. Franz Schlederer EFB 2013 VET Lichtegg – Dr. Franz Schlederer EFB 2013 Dr. Schlederer`s calf snare for calves and foals modified American calf snare VET Lichtegg – Dr. Franz Schlederer EFB 2013 CorrecEon of posiEon anomalies VET Lichtegg – Dr. Franz Schlederer EFB 2013 „Like a tennis racket“ „Fishing in the dark“ VET Lichtegg – Dr. Franz Schlederer EFB 2013 ApplicaEon during SecEo caesarea – to li` the calf‘s legs with the uterus through the open abdominal wall VET Lichtegg – Dr. Franz Schlederer EFB 2013 Headhunter ( procedure secEo caecare) VET Lichtegg – Dr. Franz Schlederer EFB 2013 Austrian young vets like my new obstetric tools and they gain more Self-confidence Thank you for your attention …and good luck in obstetrics… www. gynstick.com VET Lichtegg – Dr. Franz Schlederer EFB 2013 Merci beaucoup!
