Registered outcomes22

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryTime to Regression of Motor Blockuntil complete regression of motor block (up to 4 hours)
Time to regression of motor block is the time between maximal blockade (score 1, as evaluated by the Modified Bromage scale), and no blockade (score 6). Degree of motor blockade is assessed before and 10, 15, 20 minutes after spinal anesthesia, then every 15 minutes until the end of surgery, and thereafter, every 30 minutes until complete regression of motor block
SecondaryTime to Successful Anesthesia (Successful Sensory Block)From spinal injection of the local anesthetic to bilateral T4 level (average 20 minutes)Time between spinal injection and reached bilateral T4 sensory level.
SecondaryNumber of Participants Per Maximal Level of Sensory Block Attained After Spinal Anesthesiauntil complete release of sensory block (T12-S1) (average 4 hours)
Level of Sensory block is assessed as loss of sensation to cold, and represents the dermatomal level under which anesthesia is effective. It is measured every 2 minutes after spinal anesthesia during 15 minutes, then every 5 minutes until the end of surgery, thereafter, once 30 minutes until total regression of sensory block (T12-S1). A dermatome is the area of skin that is supplied by a single spinal nerve - Dermatome levels : C5-C8 for Cervical levels and T1-T4 for Thoracic levels. To perform cesarean section loss of cold sensation at a dermatome of at least T4 has to be obtained. The results are expressed as the number of patients reaching each dermatomal level from T4 and above (see below) as maximal sensory level, this is a usual outcome used to evaluate the quality of anesthesia.
SecondaryTime to Resolution of Sensory Blockuntil complete release of sensory block (T12-S1) (average 4 hours)
Evaluation at every 2 minutes after spinal anesthesia during 15 minutes, then every 5 minutes until the end of surgery, and thereafter, every 30 minutes until total regression of sensory block (T12-S1).
SecondaryTime to Motor Block OnsetFrom spinal injection of the local anesthetic to bilateral T4 level and during surgery (average 1 hour)
Time of installation of the motor block (time between spinal injection and maximum motor block of 1, as evaluated by the Modified Bromage scale). Degree of motor blockade is assessed before and 10, 15, 20 minutes after spinal anesthesia
SecondaryNumber of Patients With Hypotension and Use of Vasopressorsup to 2 hours after surgery
Arterial blood pressure will be measured at every 1 minute during the first 15 minutes, then at every 2.5 minutes until the end of surgery, and at every 20 minutes in the Post Anesthesia Care Unit (PACU). A low blood pressure (hypotension) is defined as a systolic blood pressure lower than 20% or more than the basal blood pressure (Systolic blood pressure before spinal anesthesia)
SecondaryNumber of Participants With Urinary Retentionup to 4 hours after surgeryAll parturients will be questioned and examined for urinary retention (yes or no)
SecondaryTime to First Walkup to 24h after surgeryTime for the patients to be able to walk in their room then in the hallway without any assistance for the first time.
SecondaryMaternal Satisfaction Assessed by Visual Analogic Scale (VASS)up to 24 hours after surgery
All patients will be asked to rate their satisfaction about anesthetic technique during surgery and in the arrival in the Post Anesthesia Care Unit (PACU). Satisfaction evaluated by Visual analog scale (0 cm= very unsatisfied and 10cm = very satisfied)
SecondaryMaternal Rehabilitation Assessed by Visual Analogic Scale (VASR)up to 72 hours after surgeryMaternal rehabilitation is evaluated at postoperative Day1, postoperative Day 2 and postoperative Day 3. Evaluation by Visual analog scale (0 cm= very poor and 10cm = excellent)
