Cross-legged Versus Traditional Sitting Position for the Success of Epidural Analgesia During Labor (IP3)
Impact of a Cross-legged Versus Traditional Sitting Position for the Success of an Epidural Analgesia Catheter Placement During Labor
The success of an epidural analgesia catheter placement depends on the parturient position. A poor posture can increase the number of punctures, patient discomfort, and risk of complications. An adequate position reverses lumbar lordosis, facilitating the access to the intervertebral space. In most cases, insertion of the epidural analgesia catheter is performed in sitting position or in lateral decubitus, the choice being generally guided by the preference of the anesthetist.
According to anesthetists' experience in the obstetrical anesthesia unit at Necker-Enfants Malades hospital, a cross-legged sitting position is comfortable for parturients, restricts interfering movements during the procedure, and provides adequate widening of interspinous spaces. This position results in knees and hips flexion, tilting the pelvis backward and opening the interspinous spaces, while limiting muscular strain to maintain the position. However, literature on this matter is scarce.
The aim of this study is to prove the superiority of the cross-legged position for successful placement of the epidural analgesia catheter at the first puncture without needle reorientation compared to a traditional sitting position on the edge of the bed.

Detailed Description
Labour pain is one of the most intense pain known. To relieve this pain, epidural analgesia is both the most effective and the safest technique. An epidural analgesia catheter also allows for anesthesia in the event of the need for instrumental extraction or emergency caesarean section; it is thus recommended by learned societies.
The 2016 national perinatal survey conducted by the National Institute of Health and Medical Research (INSERM) and the Directorate of Research, Studies, Evaluation and Statistics (DREES) in France revealed that more than 80% of women had chosen to benefit from an epidural analgesia during labour. The first puncture failure rate ranges from 3% to almost 40% depending on the study. Identified factors for difficult epidural analgesia catheter placement were: non-palpable spinous processes, obesity, spine deformity, inability for the patient to maintain an adequate position and poor experience of the operator.
The success of an epidural analgesia catheter placement depends on the parturient position. A poor posture can increase the number of punctures, patient discomfort, and risk of complications. An adequate position reverses lumbar lordosis, facilitating the access to the intervertebral space. Different positions have been described: the lateral decubitus, the traditional sitting position, and its variants such as the squatting position, the "hamstring stretch" position, the "pendant position" (with a bilateral axillary support) and more recently the cross-legged position. In most cases, insertion of the epidural analgesia catheter is performed in sitting position or in lateral decubitus, the choice being generally guided by the preference of the anesthetist.
According to anesthetists' experience in the obstetrical anesthesia unit at Necker-Enfants Malades hospital, a cross-legged sitting position is comfortable for parturients, restricts interfering movements during the procedure, and provides adequate widening of interspinous spaces. This position results in knees and hips flexion, tilting the pelvis backward and opening the interspinous spaces, while limiting muscular strain to maintain the position. However, literature on this matter is scarce.
The aim of this study is to prove the superiority of the cross-legged position for successful placement of the epidural analgesia catheter at the first puncture without needle reorientation compared to a traditional sitting position on the edge of the bed.

Intervention / Treatment |
---|---|
Active Comparator: Traditional sitting position
Expecting women are positioned in a traditional sitting position for epidural analgesia catheter placement during labour.
|
Labouring women admitted to the delivery room of Necker Enfants Malades hospital, requesting an epidural analgesia for labour, and willing to participate in our study will be randomized in the Traditional Sitting Position (TSP) group on odd days or in the Cross-legged Sitting Position (CSP) group on even days. Patients in the TSP group seat on the edge of the bed, their feet laid on a support set next to the bed. Patients in the CSP group also seat on the edge the bed, but in a so-called "tailor" position, their knees bent, their hips flexed and in abduction, their feet under each contralateral thigh. The epidural catheter will be placed according to standard local practice in either of the groups.
