Comparison Between Palpatory and Preprocedural Ultrasound Guided Techniques on Performance of Spinal Anesthesia
Comparison Between Palpatory and Preprocedural Ultrasound Guided Techniques on Performance of Spinal Anesthesia in Term Parturients Undergoing Elective Caesarian Section- A Randomized Control Trial
Pre-procedural ultrasound for Spinal & Epidural anesthesia is now being increasingly performed worldwide. Pre-procedural ultrasound assessment of the spine has been shown to facilitate the placement of epidural anesthesia in pregnant women, diagnostic lumbar punctures, performance of spinal anesthesia in non-obstetric patients and accurate identification of the interspace at which the puncture is being performed. This is especially important during spinal anesthesia, where puncture below the ending of the spinal cord is recommended for safety.
The purpose of this study is to compare the performance of spinal anesthesia between the pre-procedural ultrasound assessment of the spine and the traditional palpatory technique, in term pregnant women undergoing elective cesarean delivery. Furthermore, we aim to describe sonoanatomic features of the spine that could predict the ease of insertion of spinal anesthesia in that patient population.
We hypothesize that in term pregnant women undergoing elective cesarean delivery, pre-procedural ultrasound assessment of the spine will improve the success rate of spinal anesthesia at first attempt, compared to the traditional palpatory technique.

측정값 설명 |
기간 |
---|---|---|
Spinal needle redirections
기간: 15 minutes
|
Number of redirections needed to perform a successful spinal puncture (presence of cerebrospinal fluid).
A needle redirection is defined as any change in needle insertion trajectory that did not involve complete withdrawal of the needle from the patient's skin.
The first needle pass will not be considered a redirection.

Needle reinsertions
기간: 15 minutes
|
Number of needle reinsertions defined as complete withdrawal of the spinal needle to the patient's skin followed by a new attempt in the same interspace.
|
15 minutes
|
Need to change to another interspace.
기간: 15 minutes
|
Relocating the spinal needle to another interspace.
|
15 minutes
|
Procedure time
기간: 15 minutes
|
Time taken to perform the spinal anesthesia, measured from insertion of the introducer needle to visualization of spinal fluid.
|
15 minutes
|
Pain score
기간: 15 minutes
|
Verbal Numerical Pain Scores during the procedure (0-10, where 0 means no pain and 10 mean the worst pain imaginable).
|
15 minutes
|
Intervertebral level agreement
기간: 3 hours
|
Intervertebral level agreement between L3-L4 obtained in the postoperative ultrasound assessment and the marked intervertebral level obtained pre-procedure, either by ultrasound or palpation.
|
3 hours
|
Ultrasound Grading
기간: 3 hours
|
Ultrasound Grading: The image pattern of the intervertebral space will be categorized into three grades by three study investigators not involved in providing the spinal anesthesia: Typical Image,Atypical Image or Inconclusive Image.
