Randomized Controlled TrialA randomised trial comparing 5 mL/kg and 10 mL/kg of pentastarch as a volume preload before spinal anaesthesia for elective caesarean section.
Colloid solutions are more effective at preventing hypotension than crystalloids when used as a volume preload before caesarean delivery under spinal anaesthesia. The ideal volume to infuse has not been established. ⋯ Pentastarch, 10 mL/kg is more effective than 5 mL/kg at preventing hypotension following spinal anaesthesia for caesarean delivery.

Randomized Controlled TrialUltra-low dose combined spinal-epidural anesthesia with intrathecal bupivacaine 3.75 mg for cesarean delivery: a randomized controlled trial.
We wished to investigate the feasibility of an ultra low-dose combined spinal-epidural technique in providing surgical anesthesia for uncomplicated cesarean deliveries in a randomized, double-blind controlled trial. ⋯ We conclude that this technique results in a significantly lower incidence of maternal hypotension and has a role in high-risk parturients in whom maintenance of stable hemodynamics is imperative.

Randomized Controlled TrialIncisional and epidural analgesia after caesarean delivery: a prospective, placebo-controlled, randomised clinical study.
This study evaluated efficacy, safety and patient satisfaction with incisional analgesia with a subfascial catheter compared to epidural analgesia for pain relief following caesarean section. ⋯ Incisional local analgesia via a subfascial catheter provided satisfactory pain relief with patient satisfaction comparable to that seen with epidural analgesia. This technique may be a good alternative to the more invasive epidural technique following caesarean section as a component of multimodal pain management.

Randomized Controlled TrialPatient-controlled epidural analgesia: the role of epidural fentanyl in peripartum urinary retention.
Urinary bladder function is impaired during labor and delivery, predisposing to urinary retention. The effect of low-dose epidural opioid on bladder function remains unclear. We tested the hypothesis that adding low-dose fentanyl to epidural ropivacaine for patient-controlled labor analgesia does not promote urinary retention. ⋯ Addition of fentanyl to patient-controlled epidural analgesia did not increase the risk of urinary retention. Ultrasound measurements were effective and reliable in assessing urinary bladder volumes during labor.

Randomized Controlled TrialA randomised double-blinded controlled trial of the effect of diluent volume on the efficacy of a single dose of epidural ropivacaine for labour analgesia.
Few studies have systematically investigated the effect of diluent volume on the efficacy of epidural local anaesthetics for labour analgesia and no data are available for ropivacaine. Our aim was to compare epidural ropivacaine given in three different volumes for labour analgesia. ⋯ Under the conditions of this study, within the range of 5-20 mL, the volume and concentration were not significant factors influencing the efficacy of a single 30-mg bolus of epidural ropivacaine given for labour analgesia. This suggests that the most important factor influencing analgesic efficacy was drug mass.
