E P I D U R A L    A N E S T H E S I A - Epidural Sprotte^®Needle aka Special Sprotte^®

Avoid Wet Dura Punctures Finally a needle designed to avoid accidental “wet” dura punctures encountered during epidural anaesthesia. This epidural SPROTTE® needle (aka Special Sprotte®) is an evolution of the standard Spinal SPROTTE® needle used routinely worldwide to prevent CSF loss during spinal anaesthesia.

Reduce Risk of Catheter Damage With an Atraumatic needle

The Epidural SPROTTE^® needle incorporates a smooth catheter channel complete with rounded ramp to deflect the catheter effectively. In addition to deflecting the catheter laterally, the “rounded ramp” design is such that the catheter may be advanced or withdrawn (for re-positioning of needle) without fear of damaging the epidural catheter. In addition, the catheter channel allows for smooth insertion of a standard SPROTTE^® spinal needle for the combined Spinal/Epidural technique.

Needle Features Introducing the New Epidural Sprotte®, featuring: a—atraumatic point plus shortened effective working length of needle– features designed to avoid accidental wet dura punctures. b—rounded ramp for effective deflection of catheter c—plastic coated catheter channel for smooth insertion of catheter or Standard Sprotte® spinal needle (for the combined Spinal/Epidural technique)

Special Sprotte vs Tuohy

Illustrated at right: 16G Tuohy Needle vs. the new 19.5G Epidural Sprotte. Note that in both distal tip length and size of lateral opening, the 19.5G Epidural Sprotte compares closely to that of a 16G Tuohy needle and thus offers the clinician a familiar accomodation to the anatomical structure of the epidural space while offering a markedly less intrusive needle diameter into the patient.
