Clinical TrialQuadratus Lumborum Block: Analgesic Effects and Chronological Ropivacaine Concentrations After Laparoscopic Surgery.
The quadratus lumborum block (QLB) is an abdominal truncal block, similar to transversus abdominis plane block (TAPB). However, the characteristics of QLB with regard to its duration and safety are not well known. The primary aim of this study was to determine the block duration and the cutaneous sensory block area. Our secondary analysis included assessment of the chronological change in arterial local anesthetic concentrations after QLB. ⋯ Quadratus lumborum block resulted in a widespread and long-lasting analgesic effect after laparoscopic ovarian surgery and resulted in lower peak arterial ropivacaine concentrations as compared with those of lateral TAPB after 150 mg ropivacaine injection.

Accidental Dural Puncture Management: 10-Year Experience at an Academic Tertiary Care Center.
The use of spinal catheters for extended periods after accidental dural puncture (ADP) and administration of intrathecal saline via spinal catheters have been advocated to decrease the incidence of postdural puncture headache and the subsequent need for epidural blood patch (EBP), with mixed results observed. ⋯ Insertion of spinal catheters after ADP and administration of intrathecal normal saline via spinal catheters reduce the need for EBP compared with resiting the epidural. Administration of the standard epidural test dose intrathecally is associated with frequent and significant complications.
