An interventional study of Conventional Sitting Position and Imran Technique in Spinal Anesthesia, Lumbar Puncture and Patient Positioning, sponsored by Wah Medical college , POF hospital. Completed at 1 site in Pakistan. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-06-04.

This quasi-experimental prospective clinical trial was conducted to compare the conventional sitting position with the Imran Technique, a novel ergonomic patient-positioning method, for spinal anesthesia and lumbar puncture. A total of 200 adult participants requiring spinal anesthesia for surgical procedures or diagnostic lumbar puncture were allocated into two groups. The study aimed to evaluate procedural success, procedural efficiency, patient comfort, operator ergonomics, and procedure-related complications associated with the two positioning techniques.
This quasi-experimental prospective clinical trial was designed to compare the conventional sitting position and the Imran Technique during spinal anesthesia and lumbar puncture procedures. Adult participants aged 18 to 65 years who required spinal anesthesia for surgical procedures or diagnostic lumbar puncture were enrolled and allocated into two groups.
Participants in the control group underwent the procedure using the conventional sitting position, while participants in the intervention group underwent the procedure using the Imran Technique. The primary outcome measure was first-attempt procedural success. Secondary outcome measures included total procedural time, positioning-to-needle insertion time, number of needle attempts, needle redirections, intervertebral space changes, overall procedural success, need for operator assistance, patient comfort, ability to maintain position, operator strain, accessibility of the intervertebral space, and procedure-related complications.
The study was conducted at the Intensive Care Unit of the Department of Anaesthesiology, POF Hospital, Wah Cantt, Pakistan, following Institutional Review Board approval and written informed consent procedures.
Wah Medical college , POF hospital is the lead sponsor of 4 studies on the registry; 2 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Participants underwent spinal anesthesia or lumbar puncture using the conventional sitting position according to standard institutional practice.
Procedure: Conventional Sitting Position
Participants underwent spinal anesthesia or lumbar puncture using the Imran Technique, a novel ergonomic positioning method designed to improve lumbar flexion, operator ergonomics, and procedural access.
Procedure: Imran Technique
Standard sitting patient positioning used for spinal anesthesia and lumbar puncture procedures.
A novel ergonomic patient positioning technique for spinal anesthesia and lumbar puncture involving lateral operator positioning and assisted lumbar flexion to improve procedural access and success.
First Attempt Procedural Success
Successful spinal anesthesia or lumbar puncture achieved with a single skin puncture on the first attempt.
Time frame: During the procedure (up to 30 minutes)
Total Procedural Time
Total time required from patient positioning to successful completion of spinal anesthesia or lumbar puncture.
Time frame: During the procedure (up to 30 minutes)
Number of Needle Attempts
Total number of skin puncture attempts required to successfully complete the procedure.
Time frame: During the procedure
Needle Redirections
Number of needle redirections required during spinal anesthesia or lumbar puncture.
Time frame: During the procedure
Intervertebral Space Changes
Number of intervertebral space changes required to successfully complete the procedure.
Time frame: During the procedure
Overall Procedural Success
Successful completion of spinal anesthesia or lumbar puncture regardless of the number of attempts required.
Time frame: During the procedure (up to 30 minutes)
Patient Comfort Assessed Using a 0-10 Numeric Rating Scale (NRS)
Participant comfort during positioning and spinal anesthesia/lumbar puncture was assessed using a 0-10 Numeric Rating Scale, where lower scores indicate greater comfort.
Time frame: During the procedure
Ability to Maintain Position Assessed Using an Investigator-Defined 3-Category Scale
Participant ability to maintain the assigned procedural position was assessed using an investigator-defined 3-category scale: Easy, Moderate, or Difficult.
Time frame: During the procedure
Operator Strain Assessed Using an Investigator-Defined 4-Category Ergonomic Scale
Operator physical strain during the procedure was assessed using an investigator-defined 4-category scale: None, Mild, Moderate, or Severe.
Time frame: During the procedure
Accessibility of Intervertebral Space Assessed Using an Investigator-Defined 3-Category Operator Rating Scale
Accessibility of the intervertebral space was assessed by the operator using an investigator-defined 3-category scale: Easy, Acceptable, or Difficult.
Time frame: During the procedure
Procedure-Related Complications
Occurrence of procedure-related events including paresthesia, bloody tap, hypotension, bradycardia, or procedural failure.
Time frame: uring the procedure and immediately after procedure (up to 1 hour)
Plan to share: Yes — Individual participant data that underlie the results reported in the published article, after de-identification.
