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. As such, the practice of obstetric anaesthesia has evolved to minimize such risks. 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.
