CSE for Labour Analgesia: A Comparison of Two Intrathecal Regimens (SSS)
Combined Spinal Epidural Analgesia in Labour: A Comparison of Two Intrathecal Regimens of Single Shot Spinal
Analgesia in labour is not readily available in many parts of Sub-Saharan Africa. The overall cost of Epidural services in terms of human personnel and financial implication makes this inaccessible to many women in labour. Thus, a cheaper, less technically demanding and easier option that can produce as much satisfaction for the parturient and would allow her participate in the second stage of labour by being able to bare down is being studied.
The Single Shot Spinal (SSS) would provide pain relief in these women however its draw back is its time limitation as the option of a top up is not available.
Two regimen of drug options would be considered using opioids. These would be compared to see how well they are able to provide analgesia in women who hitherto have had vaginal birth. Their onset, duration of action and possible side effects would be compared.
NULL HYPOTHESIS: Single Shot Spinal with Bupivacaine Fentanyl (BF) cannot provide a statistically significant difference in labour analgesia in comparison with Bupivacaine Fentanyl Morphine (BFM) ALTERNATE HYPOTHESIS: Single Shot Spinal with BF can provide a statistically significant difference in labour in comparison with BFM

Gedetailleerde beschrijving
A double blinded randomized study comparing 2 intrathecal mixtures for labour analgesia.
94 multiparous parturients in active labour who have given informed consent would be recruited into the study. They would be randomly allocated into 2 groups using simple random sampling. An Assistant would know the code and prepare the intrathecal solutions.
Baseline vitals would be taken and patient's pain score noted. Due protocol would be followed and a combined spinal epidural sited but with the epidural not activated until the effect of the spinal wears off.
Routine monitoring would be done and various parameters and indices noted. Where the effect of the spinal lasts the duration of labour thus no need to activate the epidural, this would also be noted.
Data would be analysed using Statistical Package of Social Sciences (SPSS) version 20.

Primaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Time to First painless contraction (TFC)
Tijdsspanne: time zero to first painless contraction estimated 15 minutes
|
This is the onset of action of the drugs.
The time duration from the initiation of the block at time zero to the point where there is significant drop in the Numerical Rating Scale (NRS) to 2 or less
|
time zero to first painless contraction estimated 15 minutes
|
|
Time to First Request for Analgesia (TFA)
Tijdsspanne: Time zero till NRS > 6 estimated 180 minutes
|
This is the duration of action of the block.
Time from initiation of the block to time the pain score is up to 6 or more.
It is expected that after onset of the block (TFC) the pain would first become negligible or absent and after a period of time, it would gradually increase as the drug wears off.
If the pain becomes moderate at a NRS of 6 or the patient requests for analgesia, the time would be noted and the epidural would be activated.
