Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To investigate if sitting in flexed cross legged position for neuraxial techniques in term pregnant patients widens the size of the ultrasound acoustic window as measured by the visualized posterior longitudinal ligament length, during lumbar spine ultrasonography using longitudinal paramedian view, in comparison to the standard sitting flexed position.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective observational study involving a total of 30 healthy term gestation pregnant patients with singleton fetuses.Patients will be randomly allocated to sit crossed leg or in standard position first. Using ultrasonography, the acoustic window for lumbar spinal anesthesia at L3-4 will be evaluated in both traditional sitting and crossed leg positions. Ultrasonography will be performed sequentially to measure the best visualized length of posterior longitudinal ligament,ligamentum flavum and interlaminar distance in the paramedian view.The scanned image will be saved to be remeasured by a third observer. Patients will be asked to score their comfort level while sitting in both positions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Crossed leg position

Patients in this group will be randomly allocated to sit in crossed leg position first.Ultrasonography will be performed in this position to measure the best visualized length of posterior longitudinal ligament, ligamentum flavum and interlaminar distance at L3-4 lumbar level as by Operator 1 . These measurements will be recorded by Operator 2 using intrinsic caliper software.Operator 1 will not be told the measurements.

Ultrasonography

Intervention Type DEVICE

Length of Posterior Longitudianl Ligament, Ligamentum Flavum and Interlaminar distance visible in paramedian longitudinal view during lumbar spine ultrasonography in cross legged position will be compared to standard sitting position.

Standard Sitting position

Patients in this group will be randomly allocated to sit in standard position first.Ultrasonography will be performed in this position to measure the best visualized length of posterior longitudinal ligament, ligamentum flavum and interlaminar distance at L3-4 lumbar level as by Operator 1 . These measurements will be recorded by Operator 2 using intrinsic caliper software.Operator 1 will not be told the measurements.

Ultrasonography

Intervention Type DEVICE

Length of Posterior Longitudianl Ligament, Ligamentum Flavum and Interlaminar distance visible in paramedian longitudinal view during lumbar spine ultrasonography in cross legged position will be compared to standard sitting position.
