Spinal anesthesia is a safe alternative to general anesthesia but remains underrepresented in the ambulatory setting. Most concerns relate to low flexibility of spinal anesthesia duration and the management of urinary retention in the outpatient setting. ⋯ With the local anesthetics that have current approval for usage in spinal anesthesia, most requirements for ambulatory surgeries can be met. The reported evidence on local anesthetics without approval supports clinically established off-label use and can improve the results even further.

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.

ReviewIntrathecal opioids for the management of post-operative pain.
Intrathecal opioids are highly effective in the management of post-operative pain. The technique is simple with a very low risk of technical failure or complications, and it does not require additional training or expensive equipment such as ultrasound machines and, therefore, is widely practised around the world. The high-quality pain relief is not associated with sensory, motor or autonomic deficits. ⋯ With these dose reductions, the risks have decreased; current evidence shows that the risk of the much-feared respiratory depression with low-dose ITM (up to 150 mcg) is no greater than that with systemic opioids used in routine clinical practice. Patients receiving low-dose ITM can be nursed in regular surgical wards. The monitoring recommendations from societies such as the European Society of Regional Anaesthesia and Pain Therapy (ESRA), the American Society of Regional Anesthesia and Pain Medicine and the American Society of Anesthesiologists need to be updated so that the requirements for extended or continuous monitoring at postoperative care units (PACUs), step-down units, high-dependency units, and intensive care units can be eliminated, thereby reducing additional costs and inconvenience and making this simple, versatile and highly effective analgesia technique available to a wider patient population in resource-limited settings.

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.
