General Anesthesia Versus Spinal Anesthesia in Patients of HELLP Syndrome

Spinal needle 25G with Quincke's bevel will be used. It will be induced with a total of 10 mg of 0.5% hyperbaric bupivacaine and 20 mcg fentanyl (total volume 2.4 ml) at the L3-4 interspace. The parturient will be returned to the supine position with a left lateral tilt of 15° to facilitate left uterine displacement. The upper sensory block level will be checked 5 min after the spinal injection by assessing the loss of cold sensation from alcohol swabs, to ensure that a Th6 sensory block level has been achieved.

Pre-oxygenation with oxygen 100% via a tight fitting mask rapid sequence technique. Induction is by thiopental (5 mg kg lean body weight) and succinylcholine1.5 mg kg body weight), cricoid pressure should be applied before consciousness is lost and kept in place until confirmation of tracheal intubation with capnography and the cuff of the tracheal tube is inflated. Auscultating the chest helps exclude endobronchial intubation. At this point, surgery may commence.
