Analgesic efficacy of different volumes in erector spinae plane block in patients undergoing single level lumbar spine fixation: a non-inferiority randomized trial.

Background: Using a lower volume (LVs) of local anaesthetic (LA) reduces the risk of toxicity, side effects, and cost. Our study assessed whether the lower LA volumes (10 or 15 ml) have the same analgesic efficacy as 20 ml of erector spinae plane block (ESPB) in single-level lumbar spine fixation.

Methods: Our non-inferiority, randomised, double-blind trial recruited sixty cases scheduled for single-level lumbar spine fixation.

Efficacy of translamina terminalis ventriculostomy tube in prevention of chronic hydrocephalus after aneurysmal subarachnoid hemorrhage.

Background: Chronic shunt-dependent hydrocephalus is still a common complication after aneurysmal SAH (aSAH) and is associated with increased morbidity. Pathology of chronic shunt-dependent hydrocephalus after aSAH is complex and multifactorial which makes its prevention challenging. We thought to evaluate whether external ventricular drainage (EVD) through fenestrated lamina terminalis would decrease the rate of chronic shunt-dependent hydrocephalus after aSAH.
