Experimental production of arachnoiditis with glove powder contamination during myelography
Abstract:
Adhesive spinal arachnoiditis is a rare condition of several causes, including complications of myelography. An experiment was conducted to study the effects of surgical glove powder contamination in the cerebrospinal fluid. The subarachnoid space of 45 rabbits was injected with either a suspension of powder from sterile surgical gloves, Pantopaque (iophendylate), or a combination of the two agents. Mild to severe arachnoiditis was produced in 10 of 17 animals injected with the combination of powder and Pantopaque. Only two of 16 rabbits injected with glove powder and one of nine with Pantopaque had more than minimal changes of arachnoiditis. Three rabbits (two injected with glove powder alone and one with both agents) died of meningitis within 1 week of injection. The combination of glove powder and Pantopaque is synergistic in producing arachnoiditis. These results emphasize the importance of meticulous technique in myelography.
Insights
Surgical glove powder combined with Pantopaque significantly worsens adhesive spinal arachnoiditis in rabbits. Meticulous myelography techniques are crucial to prevent this severe complication.
Area of Science:
- Neurosurgery
- Neuropathology
- Radiology
Background:
- Adhesive spinal arachnoiditis is a rare neurological condition.
- Myelography, a diagnostic imaging procedure, can lead to complications like arachnoiditis.
- Surgical glove powder has been implicated as a potential contaminant.
Purpose of the Study:
- To investigate the effects of surgical glove powder contamination in cerebrospinal fluid.
- To determine the synergistic effects of glove powder and Pantopaque on arachnoiditis development.
Main Methods:
- The study involved 45 rabbits with injections into the subarachnoid space.
- Agents used included sterile surgical glove powder, Pantopaque (iophendylate), and a combination of both.
- Animals were monitored for the development of arachnoiditis and meningitis.
Main Results:
- A combination of glove powder and Pantopaque induced mild to severe arachnoiditis in 10 of 17 rabbits.
- Glove powder alone or Pantopaque alone resulted in minimal arachnoiditis in most animals.
- Three rabbits died of meningitis within one week of injection.
Conclusions:
- The combination of surgical glove powder and Pantopaque exhibits a synergistic effect in producing adhesive spinal arachnoiditis.
- These findings highlight the critical importance of employing meticulous techniques during myelography to minimize contamination risks.
