ReviewContinuous spinal technique in surgery and obstetrics.
Continuous Spinal Anaesthesia (CSA) technique has all the advantages of single-shot spinal anaesthesia with the added benefit of prolonging the duration of anaesthesia. CSA has been used as a primary method of anaesthesia as an alternative to general anaesthesia in high-risk and elderly patients for various elective and emergency surgical procedures involving the abdomen, lower limbs, and vascular surgeries. ⋯ This article includes a description of CSA technique compared to other contemporary central neuraxial blocks. It also discusses the perioperative applications of CSA for different surgical and obstetrics procedures, advantages, disadvantages, complications, problems, and pointers on how to perform the technique safely.

ReviewManagement of adverse effects of intrathecal opioids in acute pain.
Intrathecal opioids have been used for several decades in different clinical settings. They are easy to administer and provide many benefits in clinical practice, such as better quality of spinal anaesthesia, prolonged postoperative analgesia, decreased postoperative analgesic requirements and early mobilisation. ⋯ In contrast, intrathecal hydrophilic opioids may have potentially serious adverse effects, the most feared of which is respiratory depression. In this review, we will focus on the contemporary evidence regarding intrathecal hydrophilic opioids and present their adverse effects and how to manage them.

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.
