SPROTTE® - Safety Revolution in Spinal Anaesthesia

The pioneer of atraumatic spinal anaesthesia

The unique design of the Sprotte needle has made it a success. This design has revolutionised spinal anaesthesia. Pajunk is proud to have taken this step together with Prof. Sprotte.

 

Milestones of the Sprotte:

1979 - Launch

1980 - break trough in regional anaesthesia

In 1980’s - First studies confirming the concept of the Sprotte needle repeatedly. Thus increasing interest.

1990 - Scientific success of the needle - first comparative studies with Quincke & Whitacre needle. This led to the Sprotte needle with its atraumatic tip geometry becoming the new standard in anaesthesia in some parts of the world market.

 

 

However, what is so revolutionary about our Sprotte?

Atraumtic Tip Design

  • The ogive shaped tip significantly reduces the risk of PDPH³ and the rounded edges of the lateral eye minimize trauma to the dura mater. Thanks to the tip, design there is a consistent tactile feedback.

 

Lateral Eye

  • The burr-free, rounded atraumatic edges optimises the gliding properties. Additional there is a minimum chance of tissue coring and carry-over into the subarachnoid space

 

Optimal Lateral Eye Size and Placement

  • The Sprotte has an unobstructed backflow, even if the eye is partially blocked by the arachnoid membrane. This allows a quicker CSF flashback1

 

Precision-Ground Metal Stylet

  • The stylet closes the lateral eye precisely to minimise chance of tissue coring.² Further the polished, rounded tip of the stylet prevents abrasion on the inner needle tube.

Further, the Sprotte needle has also revolutionised the lumbar puncture area.

 

In comparison with the Qunicke tip needles, the Sprotte needles has an Evidence class 1, recommendation level A8,9,10,11 in the sector of lumbar puncture

The conclusion out of different studies: “It’s time to change the needle.”4,5,14 for lumbar puncture.

  • Atraumatic lumbar puncture needles are safe to use4,5,7,8,9,10,11
  • Require a minimal learning curve8
  • Provide reliable results9
  • Minimise side effects, complications, and recovery time5
  • High savings potential by minising process and treatment costs6,11
  • Increas efficiency6
