Comparative StudySubarachnoid catheter placement after wet tap for analgesia in labor: influence on the risk of headache in obstetric patients.
The incidence of postdural puncture headache (PDPH) after epidural wet tap for obstetric patients may be as high as 75%. We have studied how subsequent placement of a subarachnoid catheter immediately after confirmation of a wet tap, and leaving the catheter in place for 24 hours affects the incidence of PDPH. ⋯ Subarachnoid catheter placement after wet tap in obstetric patients reduces the PDPH rate and does so to a greater extent if left in place for 24 hours after delivery.

Influence of lumbar flexion on the position of the intercrestal line.
This study was performed to ascertain whether the position of the intercrestal line changes as a result of flexion of the lumbar spine. ⋯ When compared with the neutral position, the position of the intercrestal line usually does not change with full flexion of the lumbar spine, and even in cases in which change occurs, it does not move beyond the next level.

Case ReportsPleural effusion and chest pain after continuous interscalene brachial plexus block.
We describe a unique case of a patient who experienced atelectasis of the lower lobe of the left lung and pleural effusion manifested by chest pain after continuous interscalene brachial plexus block for postoperative analgesia. ⋯ If chest pain presents after interscalene brachial plexus block, early postoperative chest x-ray is recommended to rule out pneumothorax, atelectasis, and/or pleural effusion secondary to ipsilateral phrenic block.

Randomized Controlled Trial Comparative Study Clinical TrialA preoperative retrobulbar block in patients undergoing scleral buckling reduces pain, endogenous stress response, and improves vigilance.
This study aims to test postoperative analgesia by using retrobulbar block in patients with retinal detachment surgery. ⋯ Because the analgesic effect of the retrobulbar block was considerably longer than pharmacologically expected, the combined retrobulbar and general anesthesia "protects" against postoperative pain and is recommended for patients undergoing scleral buckling.
