Randomized Controlled TrialIs crystalloid co-loading necessary to prevent spinal hypotension during elective cesarean delivery? A randomized double-blind trial.
Hypotension is common during spinal anesthesia for cesarean delivery. Preventive strategies include fluid loading and phenylephrine. We hypothesized that if prophylactic phenylephrine infusion is used, omission of fluid loading would be non-inferior to fluid co-loading in maintaining cardiac output. We assumed that if there was a difference, the increase in cardiac output would be greater in the no-loading than in the co-loading group. ⋯ Omission of crystalloid co-loading leads to a decrease in cardiac output which has a potentially unfavorable impact on neonatal acid base status. We conclude that crystalloid co-loading may be useful in the presence of phenylephrine infusion.

Comment Randomized Controlled TrialComparative efficacy of quadratus lumborum type-II and erector spinae plane block in patients undergoing caesarean section under spinal anaesthesia: a randomised controlled trial.
Quadratus lumborum and erector spinae plane blocks have been used to provide analgesia in patients undergoing thoracic or abdominal surgeries. Our study compared the analgesic efficacy of the quadratus lumborum type-II block (QLB-II) and the erector spinae plane block (ESPB) in parturients who underwent caesarean section under spinal anaesthesia. ⋯ We concluded that patients who underwent QLB-II or ESPB reported similar analgesic efficacy, complications, and quality of recovery in the postoperative period.

Randomized Controlled TrialThe incidence of breakthrough pain associated with programmed intermittent bolus volumes for labor epidural analgesia: a randomized controlled trial.
In this randomized, blinded study, we evaluated the effects of different programmed intermittent epidural bolus (PIEB) volumes for labor analgesia on the incidence of breakthrough pain and other analgesic outcomes. ⋯ The larger PIEB volumes were preferred for epidural labor analgesia compared with a smaller volume because of improved analgesia without clinically significant increases in adverse effects.
