ReviewNeuraxial drug delivery in pain management: An overview of past, present, and future.
Activation of neuraxial nociceptive linkages leads to a high level of encoding of the message that is transmitted to the brain and that can initiate a pain state with its attendant emotive covariates. As we review here, the encoding of this message is subject to a profound regulation by pharmacological targeting of dorsal root ganglion and dorsal horn systems. ⋯ Further developments are called for in delivery devices to enhance local distribution and to minimize concentration gradients, as frequently occurs with the poorly mixed intrathecal space. The field has advanced remarkably since the mid-1970s, but these advances must always address the issues of safety and tolerability of neuraxial therapy.

This article provides a comprehensive review of the technique, drugs of choice, and potential side effects and complications associated with the drugs used and the single-shot spinal anaesthesia (SSS) technique for caesarean delivery. Although neuraxial analgesia and anaesthesia are generally considered safe, all interventions come with potential adverse effects. ⋯ This review highlights the safety and efficacy of SSS for caesarean delivery while also discussing potential complications such as hypotension, postdural puncture headache, and nerve injury. In addition, drug selection and dosages are examined as well, emphasizing the importance of individualized treatment plans and close monitoring for optimal outcomes.

ReviewCurrent indications for spinal anesthesia-a narrative review.
Spinal anesthesia is a commonly performed regional anesthesia technique by most anesthesiologists worldwide. This technique is learned early during training and is relatively easy to master. ⋯ This review attempts to highlight the current indications of this technique. Understanding the finer aspects and knowledge gaps will help postgraduates and practicing anesthesiologists in designing patient-specific techniques and interventions.

Postdural puncture headache (PDPH) may develop after an unintended (accidental) dural puncture, after deliberate dural puncture for spinal anaesthesia or during diagnostic dural punctures performed by other medical specialties. PDPH may sometimes be predictable (patient characteristics, inexperienced operator or co-morbidities), is almost never immediately evident during the procedure, and sometimes presents late, after discharge. ⋯ Failure of EBP after the first attempt is not uncommon, and major complications may occur but are rare. In the current review of the literature, we discuss the pathophysiology, diagnosis, prevention and management of PDPH following accidental or intended dural puncture, and present possible therapeutic options for the future.

ReviewSpinal anaesthesia in children: A narrative review.
Spinal anaesthesia is an established and frequently used anaesthetic technique in adults. However, this versatile regional anaesthetic technique is less frequently used in paediatric anaesthesia even though it can be used for minor (e.g. inguinal hernia repair) and major (e.g. cardiac surgery) surgical procedures. The aim of this narrative review was to summarize the current literature with regard to technical aspects, surgical context, choice of drugs, potential complications, as well as the effects of the neuroendocrine surgical stress response and potential long-term effects of anaesthesia during infancy. In summary, spinal anaesthesia represents a valid alternative in the paediatric anaesthesia setting also.
