- Brief Summary
This study aims to test the effectiveness of uSINE-PAMS technology for lumbar puncture compared to traditional landmark-based technique. uSINE is a machine-learning software designed to aid the operators in ultrasound-guided lumbar puncture while PAMS is a two-part hardware to translate data from ultrasound to accurate needle insertion and angulation.
- Detailed Description
Lumbar puncture (LP) is a routine invasive procedure performed for the diagnosis and treatment of central nervous system disorders. The traditional landmark-based method is associated with a high failure rate of up to 50%, leading to complications including back pain and epidural hematoma, diagnostic delay, and increased healthcare costs. The success rate has been improved with ultrasound guided LP but the use of ultrasound-guided LP has not been widespread due to inadequate training in ultrasound use and the inability to translate information derived from ultrasonography to the LP procedure. uSINE-PAMS was designed to address these challenges: uSINE is a machine-learning software to aid the operators in ultrasound-guided LP; PAMS is a two-part hardware to translate data from ultrasound to accurate needle insertion and angulation.
This study consists of a pilot phase to test the usability of uSINE-PAMs and allow for improvement in technology and clinical workflow for uSINE-PAMS. In the pilot phase, experienced NNI clinicians who have participated in a previous healthy volunteer study and have been trained to use uSINE will be the operators performing the uSINE-PAMS-guided lumbar puncture. During and upon completion of the study, challenges in the use of uSINE and PAMS to conduct LP as well as in the implementation of uSINE-PAMS in the clinical workflow will be determined and addressed prior to the main study, open-label single-arm phase 2 clinical trial. Ten patients will be recruited in this pilot phase.
Following the pilot phase, an open-label single-arm phase 2 clinical trial to test the effectiveness of uSINE-PAMS-guided LP against historical data of 55% from traditional landmark-based method. 50 patients who are planned for LP will be recruited to undergo LP using the uSINE-PAMS-guided technique. The overall hypothesis is that uSINE-PAMS-guided LP will achieve at least 20% improvement in first pass success rate of obtaining cerebrospinal fluid compared to historical data of 55% from traditional landmark-based technique, therefore leading to reduction in complication rates.

Group Intervention Description uSINE-PAMS-guided Intervention Arm (uSINE-PAMS-technique) Patients will undergo LP using uSINE-PAMS-guided technique
- Primary Outcome Measures
Name Time Method First pass success rate of obtaining CSF using uSINE-PAMS-guided technique against the traditional landmark-based method of 55%.technique against the traditional landmark-based method of 55%. During procedure First pass is defined as the first LP attempt without withdrawing the LP needle out of the skin.
- Secondary Outcome Measures
Name Time Method Number of needle redirections using uSINE-PAMS-guided technique. During procedure Needle redirection is defined as the number of times the LP needle was repositioned to obtain the CSF without withdrawing out of the skin.
Pain score from LP using uSINE-PAMS-guided technique. Immediately after procedure Pain score will be assessed using the Universal Pain Assessment Tool which has a scale of 0-10, with 0 being no pain and 10 being Worst Pain Possible.
Rate of traumatic LP using uSINE-PAMS-guided technique. 1 hour after procedure Traumatic LP is defined as needle-induced blood (\>5 red blood cells/ul) in the cerebrospinal fluid; Cases where red blood cells are expected in the cerebrospinal fluid will be excluded from this analysis.
Rate of back pain that develops within 24 hours of the LP using uSINE-PAMS-guided technique. Approximately 24 hours after procedure Pain score will be assessed using the Universal Pain Assessment Tool which has a scale of 0-10, with 0 being no pain and 10 being Worst Pain Possible.
