Review Meta AnalysisInduction opioids for caesarean section under general anaesthesia: a systematic review and meta-analysis of randomised controlled trials.
Remifentanil and alfentanil effectively reduce the pressor response to intubation for general anaesthesia cesarean section, without depressing neonatal Apgar scores.

Need for additional anesthesia after single injection spinal analgesia for labor: a retrospective cohort study.
There is little information about the use and efficacy of single injection spinal blocks for labor analgesia; specifically, how frequently subsequent analgesia or anesthesia is needed. This study determined how frequently an additional anesthetic intervention was needed in women who received single injection spinal analgesia. ⋯ This retrospective review provides evidence that single injection spinal anesthesia may be used for multiparous women with spontaneous labor and more advanced cervical dilation.

Randomized Controlled Trial Comparative StudyA triple-blinded randomized trial comparing spinal morphine with posterior quadratus lumborum block after cesarean section.
What did they do?
Tamura and team randomised 176 elective CS patients to spinal anaesthesia with or without morphine, in addition to placebo or ultrasound-guided quadratus lumborum block (QLB).
And they found
Only intrathecal morphine significantly improved analgesia, not QLB whether performed with or without spinal morphine. Thus QLB probably does not improve analgesia further beyond current best practices.
Not so fast...
While this modest-sized RCT concluded that QLB did not improve pain after caesarean section, the conclusion is i) somewhat inconsistent with earlier studies that did show benefit, and ii) the adjuvant analgesic regime1 used may not be applicable to practice outside Japan.
summary
-
The researchers administered the remaining 90 mcg fentanyl IV, along with droperidol 1.25 mg and acetaminophen/paracetamol 15mg/kg after baby delivery. An NSAID (diclofenac 50mg) was only provided when breakthrough pain was requested. ↩

ReviewPost-caesarean delivery analgesia in resource-limited settings: a narrative review.
Post-caesarean pain is an important and often neglected outcome. It causes suffering, affects breastfeeding and is associated with postpartum depression and the development of chronic pain syndromes. Pain control is often difficult even in resource-rich environments; it is likely far worse in resource-limited settings, where emphasis is on reducing the high maternal mortality rate. ⋯ Solutions using affordable and accessible medications as part of a multimodal analgesic strategy are possible, supplemented by education and training programmes. More research is required, both to establish current practice and to test methods for improving maternal pain control. While government involvement is necessary to improve infrastructure and resources in individual countries, other solutions should also be sought, empowering local institutions and harnessing individual cultural characteristics.

Observational StudyLabor epidural analgesia onset time and subsequent analgesic requirements: a prospective observational single-center cohort study.
We investigated the correlation between lumbar epidural analgesia onset time and pain intensity at 60 and 120 min after initiation. ⋯ There was a correlation between the onset time of lumbar epidural analgesia during labor and the pain score 60 min later but this had disappeared by 120 min.
